To provide the new engineering so-phistication required, he forecast that there will be continuing education courses in the newest technologies for many 40-year-old engineers.

Panel discussion planned for IEEE Reliability Symposium

Highlighting the 11th National Sym-posium on Reliability and Quality Con-trol, to be held January 12-14 in Miami Beach, Fla., will be a special panel dis-cussion, arranged to explore the rela-tionships, problems, and procedures incident to satisfying contractual relia-bility requirements by big business and small business.

A presentation of views on this im-portant managerial and technical issue will be made by J. B. McChesney, man-ager, Central Procurement Agency, Lockheed Aircraft Corporation, who will develop the large company view-point, and R. H. Williams, president, Harrison Manufacturing Company, who will present the small company view-point. This will be followed by a review and discussion by E. W. Brackett, Assis-tant Deputy Associate Administrator, National Aeronautics and Space Admin-istration Headquarters, representing a government procurement agency. A re-view will be presented by L. G. Odom, Jr., Staff Director and General Council, Select Committee on Small Business,

Model SSG-1 combines, for the first time, voltage accuracy with the traditional Gertsch frequency accuracy in one compact unit. This all solid state Signal Generator/Frequency Meter has a range of from 10 kc to 500 mc with direct digital control and readout. Provides increments as small as 1 cps in the range from 10 kc to 50 m c . a s small as 10 cps from 50 to 500 mc. Stability throughout the total range is 1 part in 107. Even higher stability is obtainable by driv-ing the system with a higher precision 1 mc oscillator. Direct frequency display is provided by Nixie readout, with digital dial-in of fre-quency. Output may be set to 0 dbm and adjusted 0 to - 1 3 0 db with a con-tinuously variable calibrated attenuator. Internal amplitude modulation to 50% at 400 or 1000 cps is available by means of front-panel control, and there is provision for external AM modulation to 10 kc. Non-harmonically related spurious signals are at least 60 db down. Measures frequency from 10 kc to 1 Gc.

This range is extendable to 10 Gc by means of an accessory harmonic generator-mixer assembly. For complete details and applications as-sistance, contact your nearest Gertsch representative, or the address below, re-questing Bulletin SSG-1.

U.S. Senate, representing a government small business committee. There will be a general question and answer session. This panel discussion will be moderated by B. C. Monesmith, vice president, manufacturing, Lockheed Aircraft Cor-poration.

The primary purpose of this panel discussion will be to attempt to clarify the responsibilities of customers, prime contractors, and subcontractors in the translation and transferrai of customer reliability needs between large and small organizations. These needs must be de-veloped so that large business will be capable of interpreting them for their subcontractors and respecifying them without unduly penalizing small business organizations. A determination as to what is required to procure, produce, and supply a reliable product is needed so that a reasonable, workable, and eco-nomic trade-off can be established be-tween specifications, work statements, and actual requirements reliability. The relationships between contracting, cost, and specifications will also be discussed.

Technical papers invited for INTERMAG Conference

The 3rd International Conference on Nonlinear Magnetics (INTERMAG) will be held April 21 to 23 in Washing-ton, D.C., at the Sheraton-Park Hotel. Papers are particularly solicited in the following fields: computer magnetics,

superconducting devices, magnetic re-cording, ferrite microwave devices, in-strumentation and control, combined magnetic and semiconductor devices, and magnetic material properties.

Abstracts of 250 words or less, type-written and single spaced, should be submitted as soon as possible. Strict deadlines of November 2, 1964, for abstracts, and January 15, 1965, for completed manuscripts will be observed. All manuscripts, if adequately pre-pared, will be included in the Confer-ence Proceedings which will be made available at the conference. Manuscripts should conform to the IEEE Author's Guide and have a maximum length of eight single-spaced typewritten pages including approximately one-half page for each figure.

Abstracts, manuscripts, and inquiries should be addressed to: Dr. E. W. Pugh, IBM Components Division, De-partment 231, Building 703-2, Pough-keepsie,N.Y. 12602.

Featured with the technical program will be an exhibit of commercial ma-terials, devices, and apparatus. Com-panies desiring exhibit space are invited to contact: J. L. Whitlock Associates, 253 Waples Mill Road, Oakton, Va. 22124.

The term nonlinear magnetics refers to technologies in which magnetic saturation or magnetic-field-induced nonlinear transformations are an essen-tial feature in the function of the device or system.
