NEW SEISMIC TIME DOMAIN FILTER SYSTEM ANNOUNC ED BY HTL New instrument ation for linear or non-linear filtering of noise from broad band energy has been developed by Houston Technical Laboratori es, Instrument ation subsidiary of Texas Instrument s Incorporate d.

This

Time Domain System, named the magneFILT ER, is particularl y useful in seismic exploration where the separation of desired signals from noise background is of vital importance . The magneFILT ER is a specialized analog computer using the cross correlation technique.

The trace to be filtered is compared at

each instant of time against a filter transient which has been computed from the amplitude and phase conditions desired of a particular filter. The sum of the products of samples from both trace and the transient at any instant of time becomes a running correlation between the two. The magneFILT ER is expected to have greatest utility as a research and design tool, wherever the separation of low frequency signals from noise is important.

With the magneFILT ER, a wide variety of filters

may be simulated, obviating actual constructio n of the filters. (more)

page 2 magneFILTER

Several methods of filter i ng are commonly used to facilitate separation of signals for visual interpretation of seismograms .

These

include instrumental filtering by electr i cal networks, arrays of seis mometers , compositing of seismometer outputs with various relative time delays, etc. - -all of which may be classified as general filtering operations .

With the magneFILTER ~ it is possible to simulate any of

the general filters, plus a wide vai:iety of other linear or non-linear filters which may be useful in experimental investigations.

_9r, with

filter phase and amplitude characteristic s somewhat individually adjustable, any critical data can be repeatedly examined for optimum filtering as an aid to final interpretation . Physically, the magneFILTER is a single-channel unit to be used with a multi-trace magneDISC by utilizing programmed seq_uential trace-by-trace playback. A reco;rding head, 18 reproducing heads, and an erasing magnet are evenly spaced around the periphery of a 10-inch diameter drum coated with red magnetic oxide .

In typical operation,

the filter operator length is 45 milliseconds , with head spacing or sampling points at 2 . 5 millisecond intervals . Associated electronics include a recording head modulator, individual demodulators for each pick.up head, individual potentiometers , and a summing amplifier . Thi s description. applies to the typical magneFILTER .

Such features as dr,um diameter,

drum speed, finite head spac ing, and oth er specifications may be altered to fit individual requirements . (mor e )

page 3 magneFILTER

In addition to its very flexible filtering applications, the magne­ FILTER has other seismic data processing uses .

It may be used to introduce

time corrections in raw magnetic-reco rded data , and for compositing seismometer group outputs with variable relative delay to emphasiz.e signals with particular angles of incidence . The magneFILTER , another Seismation system, is an important component in the completely integrated automatic data reduction and analysis systems being developed by Houston Technical Laboratories .

TEXAS INSTRUMENTS OPENS NEW HOUSTON TECHNICAL LABORATORIES PLANT

HOUSTON, Oct. 28 - -(Special)- - Houston Technical Laboratories, Instrumentation subsidiary of Texas Instruments Incorporated, formally dedicated its new plant with Open House ceremonies this week.

Activities included the

regular monthly meeting of the Texas Instruments board of directors at the new plant Thursday, and an Open House for employees and families, customers and guests Friday. Houston Technical Laboratories develops and manufactures a wide range of geophysical and industrial instruments.

It is a leading producer of the

equipment used in the worldwide geophysical exploration for petroleum by Geophysical Service Inc. --the Texas Instruments Exploration subsidiary--and others. The HTL new main plant has 40,000 sq ft of space on the first floor for

offices, laboratories, and manufacturm.g. There is a 40,000 sq ft area under the plant for storage and parking.

The plant and outside parking area are

situated on a five-acre tract at 3609 Buffalo Speedway in Houston. The HTL plant is larger than the entire TI company plant of just ten years ago!

Total Texas Instruments office and manufacturing space is now over 400, 000

sq ft--a tenfold growth--and the $40 million-plus sales volume predicted for this year represents a fifteen-fold growth in ten years! (more)

page 2 HTL One of the plant's many unique construction features is a 28 x 30 ft skylighted tropical garden- -symbolic of the company's worldwide operations - adjacent to the lobby and visible from all areas inside the plant.

Separated by

a glass wall from the garden is an 180 x 120 ft unobstructed manufacturing area offering great flexibility in the arrangement of equipment manufacturing lines. The building is covered by light gray Georgia marble, features large glass areas, harmonious color schemes throughout, and is completely air conditioned both for the comfort of its several hundred occupants and as an aid in the highly precise manufacturing operations.

Ford, Colley, Tamminga

were the architects and the Braselton Construction Company of Corpus Christi was the building contractor. 'GEOPHYSICAL RIBBON-CUTTER' USED An HT L Blaster - -ordinarily used to set off the explosive in seismic exploration--was used to light a fuse suspended across the building entrance in the "ribbon-cutting" ceremony.

The company co-founders, Eugene McDermott,

chairman of the board of Texas Instruments, and Dr. J.C. Karcher, now president of the Concho Petroleum Co., assisted by Cecil Green, chairman of the board of GSI, all pressed switches in unison to activate the "geophysical ribbon-cutter .." Principal speaker at the dedication was J.E. Jonsson, president of the parent firm, Texas Instruments.

He stated that the TI policy of ''concentration

on the future is an important r.eason why the company is one of the fastest growing firms in the nation" and that the HT L building itself is "an expression of our confidence in the future. " (more)

page 3 HTL The HT L Open House took place in the 26th year of the company, which employs over 4000 persons, is publicly owned, and is also an important factor in the fields of commercial and military electronics.

Mr. Jonsson explained that

this amazing growth "has come about through a logical extension of our original and basic geophysical exploration and instrumentation interest.'' The company got its start as the fir st independent geophysical exploration service specializing in the reflection seismic method.

Through subsidiary

Geophysical Service Inc. it is still the leading geophysical exploration contractor, and through subsidiary Houston Technical Laboratories is a leading producer of geophysical exploration equipment. HTL PRESIDENT WELCOMES COMPETITORS Robert W. Olson, president of HT L, in his dedication acceptance speech stated that "we will try to make our equipment as outstanding in the today's verdant technical climate as was the equipment of 26 years ago in the then existent technical desert. "

Mr. Olson welcomed visiting employee families, customers, and

especially competitors, "who, second only to our traditions , are spurs to the excellence which we wish to attain. '' Principal instruments produced by Houston Technical Laboratories are the Worden gravity meter (of which more are sold than all other types combined}, reflection and refraction seismic systems, and photographic, magnetic, and ink-writing recorders. HT L manufactures all the commercial recording instruments in the Texas Instruments family of companies. ·

Houston.

One of the Southwest's fastest growing firms manufacturing electronic

equipment, officially opened its new plant in Houston, Texas, Friday, October 26,

1956, with a great cloud of smoke set off by an impulse from one of the company 1 s products, an electric dynamite blaster. Houston Technical Laboratories, instrumentation subsidiary of Texas Instruments Incorporated, world's largest manufacturer of transistors and a leader in the de­ velopment of semi-conductor materials, was officially presented its new building by J. E. Jonsson, President of TI. The HTL building, one of the first precast, prestressed concrete buildings in Houston, houses the research and manufacturing facilities of one of the world's largest producers of seismic exploration equipment.

The Worden Gravity Meter,

the most widely used portable gravity meter and the r e c t i / r i t e r, the only true wave form inscribing galvanometer recorder, are also manufactured in the completely air-conditioned plant. 40, 000 square feet of floor space have been arranged within the building for flexible use in the expansion of the company.

Inside walls are constructed of plate

glass and plywood backed by sound damping material. can be easily moved as the need arises.

Departmental partition walls

Included in the basic design are provisions

for compatible additions of space almost equal in size to the present building. Houston Technical Laboratories was organized in 1946 by Sam Worden for the construction and distribution of the quartz element Worden Gravity Meter.

The

Page 2

gravity meter developed by Sam Worden combines the features both of light weight and internal compensati on for temperatur e variation without special heating or cooling units.

In 1953, Texas fustrument s Incorporate d, a publicly owned company, located in Dallas, bought HTL from Mr. Worden and transferred the manufactur ing of the TI seismic equipment to Houston from Dallas. Texas Instrument s is an outgrowth of Geophysica l .Service Inc., the company formed in 1930 by Dr. Karcher and Mr. McDermot t in connection with their develop­ ment of seismic equipment and exploration methods.

Always retaining its lead in

the seismic exploration field, GSI still has more operating crews than any other independen t exploration company in the world. The new plant building was officially turned over to Robert W. Olson, President of HTL, by J. E. Jonsson, President of the parent firm, Texas Instrument s.

Mr.

Jonsson stated that the TI policy of "concentra tion on the future is an impo.rtant 1 reason why the company is one of the fastest growing firms in the nation' , and that

the HTL building itself is "an expression of our confidence in the future".

TEXAS INSTRUMENTS INSTALLS 2-1/2 TON 'ELECTRONIC BRAIN'

DALLAS, December 2 - -(Special)- -Texas Instruments Incorporated, Dallas based electronics and geophysics firm, has completed the installation of a new electronic computer, Mr. C. J. Thomsen, Control and Finance division vice president, announced today.

The high speed device contains some 3000

semiconductor diodes, 2000 vacuum tubes, and weighs 5300 pounds. Its high computational speeds will spare Texas Instruments scientists the drudgery of prolonged routine mathematics and allow them to concentrate on creative research.

TI plans to use the devic~ for research computations

in geophysics , solid state physics, electromagnetic radiation, optical com­ ponents, navigation, and sound propagation.

It will be particularly helpful

to TI research in "Seismation, " the processing and reduction of geophysical data by automatic electronic means. Dr. J. A. F. Gerrard, TI Director of geophysical research, is respon­ sible for research programming of the machine and Stan Amstutz, data processing supervisor, is in charge of its actual operation .

It has been installed

in an air -conditioned sound-proofed room along with other computational machines in the Data Processing section at the TI main plant, 6000 Lemmon avenue. Called the IBM 650 Magnetic Drum Data Processing Machine, it i s already being used in advanced problems of r e::3~ arch and complex procedures (more)

page 2 electronic brain

of accounting.

It will add or subtract I 0-digit numbers at a rate of about

200 per second, will multiply two IO-digit numbers 60 times per second, and will divide 19-digit numbers by IO-digit divisors 50 times per second. In addition to high computation speeds, the machine features a "memory" which will store up to 20, 000 bits of information on a magnetized drum whirling at 208 revolutions per second.

Desired information is "remem-

bered" in less than three-thousandths of a second.

Dr. Gerrard stated that

the computer will be able to perform in minutes problems that ordinarily take days to complete. In addition, other business uses are the calculations necessary for payroll, personnel statistics, sales analyses, and billings for the 4300-employee, $44, 000, 000 firm. In the time remaining, it will work on advanced problems of research and engineering that are vital in the continued success of a highly technical company like Texas Instruments.

TI is a leading producer of commercial

electronics components--such as transistors and diodes, resistors, and transformers used in these "electronic brains" - -and military electronic apparatus.

Through subsidiaries Geophysical Service Inc. and Houston

Technical Laboratories, TI is also a leading factor in geophysical exploration and instrumentation.

TEXAS INSTRUMENTS PRESIDENT SPEAKS BEFORE N. Y. SECURITY ANALYSTS DALLAS, December 13--(Special)--Mr. J . E. Jonsson, president of Texas Instruments Incorporated, today was the featured speaker at the regular meeting of the New York Society of Security Analysts.

He explained how the electronics and geophysics firm

had increased its sales volume twenty-fold since 1946. Mr. Jonsson stated that "Contrary to common concept, our increased earning power may be attributed almost entirely to internal development and probably will so continue. " Purchases since late in 1953 involving Houston Technical Laboratories, Wm. I. Mann Co. ~ Burlington Instrument Company, and Radell Corporation--together with the convertible preferred stock is sue - -represent a total dilution of less than 10% of stockholders equity while earnings have risen 75% from 1954 to 1956. For the future, Mr. Jonsson forecast 1957 sales in the neighborhood of 60-65 million dollars, a sales rise comparable to 1956 1 s 50% increase.

He predicted definite increases

in: Texas Instruments geophysical exploration and instrumentation activities aided by rising petroleum demand, sales of transistors and other semiconductor products of which TI is a leading manufacturer, and sales of military electronics systems aided greatly by the trend to transistorization.

Mr. Jonsson stated that he believed Texas Instruments

to be "the world's largest manufacturer of transistors, measured either in numbers or dollar volume. " He forecast transistor markets of $34 million in 1956, $150 million in 1961 , and $225 million in 1965. Texas Instruments designs and produces complete airborne electronics apparatus ~n addition to transistors and other electronic components.

"We think it not unlikely

that every dollar of business developed for transistorization should yield 10 dollars worth of apparatus business within a three to five year period, 11 Mr . Jonsson said. ' -30-
