2. .Approval of Proposed Membership 

The ChfUrman welf'lomed Lt. Col. Thew J. Ice, representing the Armed Servioea 

Eleotro-Standards Agenoy, to the Panel. 

The Panel noted the approval, by the Bteer:a.ng Conuni ttee, of the nominations tor iil8iilbership on the Subpanela.

$ • Master Plan f'or Components 

J. H. Koenig, Chairman of the Ad Hoo Group appointed to stud¥ a plan for 

the adoption of a oommon code and pattern tor use in the Master Plan tor 

Components, dl.Bcusaed the details of the problem. Emplo~ent of various 

types ot codes by the Subpanels for their speoifl.c needs resulted in 

oomplioat1ona for unification of ooding necessary for a possible single 

Master Plan Chart. Dr. Koenig sugfested that the scheme adopted by the 

Subpanel on Eleotro-Meohanical Dev oes be pursued by other Subpanels in 

the modif ioation of their present Charts in an attempt to attain a common 

basis. s. Glassman, Chairman of the Subpanel on Electro-Mechanical Devices, was requested to forward copies of his Chart to all Subpanel Chairmen. In the mearztime, the Churman of the Panel requested the Ad Boo 

Group to oontinue their review an:l consider additional suggestions .trom 

members of the Panel. 

4e' Program Guida.nee Report 

The Chairman !Xflained the procedure for the asse:inbly ot material in the 

Program Guidance Report. Se"9'eral Subpanel Ohai.rmen proposed modifications and ad.di tions to the Report which were approved. The Panel agreed 

that this report was a logical presentation of the valid and essential 

rpquirements in the departments and that these problems could be overcome ~y additional fund.a. The Panel telt tha.t the current program does not 

have a suf'fl.oient amount of ~damental 1nve,tigation in proportion to the 

n.atoP-gapn developments. The Chairman requeate«i all Subpanel Chairmen 

to review their program with this idea in mind. 

The Panel requested the Secretary to diBBeminate that portion of the report 

which delJ.J1eates gaps in the components program to other Panels in the 

Committee aa.4 tb.e Board. Thia action will stimulate other aotiv1ties in 

tbe RDB to reV'J.&W their needs tor electronic components and forward their 

requirements to the Panel. 

The Program Guidance Report was unallimously afproved as amended. 

2 
• 6e Revision of Summary Charts 

The Secretary distributed EL 71/3 whl.oh is a memo for Panel and Subpanel 

Chairmen on the proposed form for the New Summary Charts. E. A. Speakman, Executive Director, stated that the form propoaed ma.y be modified 

by the Panel to define speoific items more expressively. A. W. Rogers 

suggested that the "magnJ.tude" (paragraph 2.s of EL 71/3) be divided into 

two oolumnaJ one for past obligations and the other for future obligations. 

This suggestion will be oonsidered by the Secretariat in the formulation 

of the IBM preparation of the Summary Chaz-ts. The Chairman requested all 

Subpanel Chairmen to submit to the Seoretary by l February 1950 the modified •ummary charts with the most recent information. 

s. Production of Ductile Bismuth Wire 

J • Maraten in.formed the Panel of the feeling, thus ta.r, that no potential 

use can be found for duotile bismuth wire in the field of the Subpanel 

on Resistors. Its coefficient of magneto-resistance is claimed to be 

approximately 7% per kilogru and it is felt that this is too small to be 

ot any great value. Background information has been forwarded to the 

Subpanel on Coils, Inductors and Transformers tor further investigation. 

The Air Force representative plotted a series of curves on the determination of resistance variation as a functioii of' magnet10 inten.lili ty a.t constant Foom temperature and resistance variation as a function of' tempera.-

ture. One copy of' these charts are available in the of'f'J.ce of the 

Seoretariat. 

7 • Assigpment of Component Cogm.zance 

The Chairmen discussed the results of' his oonversa.tion with two Panel 

Chairmen in the Committee on Equipment and Materials w1 th regard to the 

responsibility for ooordinat1on of' apeoific areas in the field of componente 

The Panel agreed with the Chairman to tranai'er to the Panel on Electrical 

Equipment the responsibility for rotating machinery, such as prime power equipmen~~ on the basis of delegation in lieu of setting up for greater 

aotivityw1th1n the Panel on Components. It was fointed out that the 

Panel on Components would still retain the initiative for preparing gemral 

requirements for proJects in this area. The tran-f'er ot oogn1zanoe for 

vibrator pack converters and hook-up and magnet w1~e was deferred at this 

tlll:S due to the peculiar need w1th:i.n the .f'l.eld of components. 

The Chairman further discussed the division of responsibility between the 

Subpanel on Dielectric Materials and the Panel on Organic and Fibrous 

Materials• It was J?Ointed out that the Panel on Organic and Fibrous 

Materials haa an alinoat exclusive interest in the physical. properties of' 

plastics and other organic and tibroqs materials for end applications 1l1 

auoh items as paraahutes, olothizig, tents, power equipment, eto. Further

discussion between the two ChaJ.rm.en is necessary in order to arrive at 

an appropriate line of demarcation between the two aotivities to preclude ' 

any duplication. 

8. Elaboration of lfun.itions Board Circular No. 39 to Provide Further Informat•on Concerning Jtrategio and Critical Materials 

The Chairman designated H. w. Lord to collate the informatJ.on submitted by 

all Subpanel Cha~rmen into a Panel report due in the office of the 

SeoretarJ.at by 15 February 1950. This report will be ava1lable for approvt 

by the Panel at the next meeting and subsequently consolidated into the 

Committee report. 

9. Other Business 

9el The Secretary advised all Subpanel Chairmen to prepare a record of any 

agreement concerning the assignment ot a proJect or proJects to a 

department during the Subpanel meeting. The Com.ittee on Electronics 

has re~uested a per1od1c list of such assignments. Attached as 

LET 40/2.2 11 an example of the type of in.t'ormat:i.on required. 

9.2 The Secretary informed the Panel of a request by the Joint Electronics 

Committee :i.n the Illlun1t1ons Board tor 1ndicat1on of the service which 

has been assigned pr1mary responsibility for the research and develop~ 

ment of a list or component items. The Panel noted that th:i.s list 

ot proJeots was not concerned w:i. th research and development since 

they were assigned JAN and ASESA. project members. The Secretary was 

requested to reply to the M'un:Ltions Board. 

9.3 The Secretary was 1natruoted to forward a problem. conaernedw1th 

cocrd.J.nat1on between the Panel on Components and the Panel on Test 

Equipment. tor research and development on cavities (considered as 

both a component ani frequency meter). to the Subpanel on Frequenoy 

Control Devices for implementation. 

9.4 The Secretary read a portion of the minutes of the Panel on Electron 

Tubes. held 14-oct'ober 1949. w1th regard to a recommendation for trans 

ferr1ng responsibility of ballast tubes to the Panel on Co.mpcnents. 

Thia item was deferred until the next meeting and J. Marsten will discuss th:i.s problem at that time. 

9.5 Due to the :i.nactivity of the Subpanel on Magnetic Materials in the 

Comm:i.ttee on Basic Phys1cal Sciences 1 an Ad Hoo Group on Magnet1c 

Materials was established in the Panel on Components under the 

Chairmanship ot L. c. Hicks. Service members were requested to. 

submit nOllll.nationa to Dr. 1h.cks. It was suggested that the or1ginal
