Title: Method and apparatus for geodetic direction-finding
IPC: G01S17/06
Filed: 1964-12-31
Abstract: 1,056,620. Photo-electric direction-finding systems. F. FRUNGEL. Dec. 31, 1964 [Jan. 3, 1964], No. 53008/64. Heading H4D. In a system for determining the relative bearing of two locations not in a direct line of sight, ultra-violet pulses of wavelength between 1800 Š and 2500 Š are transmitted in a narrow beam from one location and after atmospheric scattering are detected by a receiver, at the other location, whose optical axis is directed so as to intersect the transmitted beam. A transmitter T comprises a gas-filled flash-tube 18 which is sparked periodically, providing a high-intensity source of ultra-violet radiation which is collimated by a mirror system 21. A receiver R comprises a mirror system 14, 15 directing incident radiation through an adjustable-width slit 13 on to a photo-cell or photo-multiplier 12 triggering a monostable circuit. The receiver R is rendered insensitive to daylight by a filter between the mirror system and photo-detector 12. In a preferred method of use the receiver optical axis is directed vertically and the transmitter T, whose optical axis makes a small angle with the horizon, is rotated about a vertical axis until a signal is obtained from photo-detector 12, this signal being relayed back to the transmitter location by radio or telephone. A coarse measurement of bearing is made with slit 13 wide open, and a precision measurement is then made by reducing the slit width. The apparatus may be used with conventional theodolites. Examples of materials used in the construction of the transmitter T and receiver R are given. In an alternative method, the positions of the transmitter T and receiver R are reversed.

Abstract: 1,180,777. Glass - - to - metal seals. ISOTRONICS Inc. 27 Nov., 1967, No. 53747/67. Heading C1M. An hermetic seal component, especially for use with capacitors, comprises a terminal of tantalum or niobium extending through a mass of glass fused thereto and forming a positive meniscus with respect to the terminal, the glass having a coefficient of expansion greater than that of the metal of the terminal, the surface of the metal terminal being substantially free of any oxide so that after assembly of the seal an electrolytic oxide may be formed thereon. Preferably the glass has a coefficient of expansion of 9 x 10<-6>/‹ C. In the preferred form of the invention the seal component is also sealed into a metal eyelet, of silver or silver-clad steel or stainless steel, the metal of the eyelet having a coefficient of expansion at least as great as that of the glass. If desired, the eyelet may be very thin so that it follows the expansion and contraction characteristics of the glass to which it is bonded. To obtain a good hermetic seal the components are heated to a temperature of 1900‹ F. in an inert atmosphere, and after cooling to room temperature in that atmosphere an oxide is electrolytically formed on the metal terminal at the glass-terminal interface. A suitable sealing glass is a potash-soda-lead or metallic-oxide type.

Abstract: 570,158. Inductances. STEVENS, R. J., and BURNHAM, T. H. Oct. 25, 1943, Nos. 17522 and 17523. [Class 38 (ii)] [Also in Group XXXVI] Electrical components such as inductances employ thin metallic films obtained by depositing, for example, by electro-deposition, a coating of the metal which is to form the film, upon a thin sheet of a dissimilar metal and then dissolving the latter so as to leave the film floating on the surface of the dissolving liquid. To facilitate removal of the film, the liquid has added to it a little ethyl or higher alcohol to reduce the surface tension, or the film may be transferred by a sheet of glass to a tensionreducing liquid bath. To facilitate its eventual adhesion to a carrier or backing, such as a rod, the foil is passed to a bath containing isinglass and a preservative such as formaldehyde. After application to its support, the film may be further treated electrolytically to alter its thickness throughout or at localized zones, such as for building up terminals. A helical cut may be made in the film to leave a helical conducting covering on the support. In obtaining gold foil, the gold is plated on to a copper foil which is then treated with silver nitrate to replace the copper with silver, which is then dissolved in nitric acid. Other metals referred to are silver, lead and bismuth. Suitable materials for the supports are porcelain, glass and plastics of the phenolic, urea, or cellulose acetate types.
