Patent GB-606626-A (GB)
Title: Improvements in translating devices for electric waves and methods of preparing them
IPC: H01L29/00
Filed: 1946-02-27
Abstract: 606,626. Crystal detectors. WESTERN ELECTRIC CO., Inc. Feb. 27, 1946, No. 6129. Convention date, Dec. 14, 1944. [Class 40 (v)] A rectifier element is made by casting an ingot from a quantity of silicon of high purity, to which has been added before fusion a small amount of a metal which produces ions comparable in size to the interstices in the lattice structure of the pure silicon, shaping. an element from the ingot, heat treating the element to produce a thin surface layer of pure silicon, and applying an electrical stress to ionize the added metal and to cause the ions to lodge in the interstices in the surface layer. A suitable metal to add is aluminium, which is added in a proportion determined as described in Specification 602,140. A thin slab 3 cut from the ingot is polished and heated at 1050 C. for two hours to produce a layer of vitreous oxide over a thin layer of crystallised pure silicon. The back surface is then polished and nickel-plated and soldered to a brass cylinder 5 inside a cylinder 4 of steel or beryllium copper. A tungsten contact wire 8 having its end ground flat is spot-welded to a nickel pin 6 held in an insulating member 7 made of phenolic resin with a powdered quartz filler. The rectifier 12, 13, Fig. 4, is conditioned by placing it in circuit with a source 15 of alternating current and a load 16 arranged as an harmonic generator. In addition, a D.C. bias from a source 19 may be applied across byepass condenser 17 under control of a key 21. Assuming that the rectifier element 12 is electropositive, the self-bias due to rectification will tend to cause the ions of impurities in the silicon away from the rectifying surface. The large bias from source 19 acts in the opposite direction. As a result, when key 21 is closed, some of the large aluminium ions together with other ions are driven into the surface layer. When key 21 is opened, the ions tend to return to the body of the element, but the larger ions tend to remain in the interstices of the lattice structure of the silicon. Thus, after a number of closures of key 21, the surface layer becomes saturated with aluminium ions which produces a stable element of good rectifying quality.

Filed: 1937-03-02
Abstract: 496,538. Automatic control systems. FIFER, A. J. J. March 2, 1937, No. 6238. [Class 38 (iv)] [Also in Groups II and I] Concentration.-In a process in which ores are concentrated by gravity separation in a medium comprising a suspension of solids in water, the medium is supplied to the separating vessel from a conditioning tank 91. To maintain the specific gravity constant a portion of the medium from the tank is periodically weighed and either water or more concentrated medium added to the medium in the tank. Medium from the tank is run through a container 121 which constitutes one end of a balance arm 122, on the other end of which is an adjustable counterweight 122a, the medium normally passing back to the tank. Periodically a timing device 129, through an electric circuit, closes a valve 123 at the bottom of the container which then fills with medium. A float 127 then closes another electric circuit which cuts off the flow of medium and releases a clamping device 126 which normally holds the arm 122 horizontal. The container 121 rises or falls according to whether the specific gravity of the medium is too small or too great and the other end of the arm 122 contacts with stop 141 or stop 139. In either case an electric circuit is closed which adjusts the specific gravity of the medium in the tank, in one case by starting a pump 93 which passes heav y medium into the tank, and in the other case by opening a valve 102 in the water supply line. After a determined period, the timing device operates to break the various circuits and to restore the flow through the container 121.
