Patent GB-820289-A (GB)
Title: Improvements in or relating to the electrolytic treatment of semi-conductor material
IPC: H01L21/00
Filed: 1956-11-26
Abstract: 820,289. Semi-conductors; electrolytic etching and plating. PHILCO CORPORATION. Nov. 26, 1956 [Nov. 25, 1955], No. 36071/56. Classes 37 and 41. An alloy region is produced between a semiconductor body and a metal by depositing the latter electrolytically on the surface of the body and simultaneously heating the interface to produce alloying. The resulting device may be used as a rectifier, or the deposited metal may form the collector or minority-carrier emitter of a transistor, in the latter case two such regions usually being formed on opposite surfaces of the body to act as emitter and collector respectively. The deposition is preferably carried out by directing a jet of electrolyte 13 (Fig. 1) on to the body 8 with or without another jet 14 on the opposite side. A p.d. is established between the two by means of electrodes 22, 24 attached to a source of E.M.F. 26 by a changeover switch 28. Thus the operation may commence with electrolytic etching of the surface of the body to give the desired profile and deposition of metal then caused to begin by reversing the p.d. Heating is produced by radiators 50, 60, supplemented by coils 40, 41 to warm the electrolyte, so that the temperature of the latter may be equal to, higher than or lower than that of the body. The electrolyte temperature should be above the melting point of the metal deposited (or any eutectic formed with the material of the body) and below the decomposition point of the solvent used. The temperature of the body should be equal to or above the eutectic temperature with the alloying metal. When two jets are used the temperatures of the electrolyte and body may differ on the two sides. It is possible to start the hot jet before the electrolytic current, and to terminate the latter first, when additional heating is required. In a typical case the electrolyte consists of indium trichloride and ammonium chloride in ethylene glycol, the operating temperature being between 156‹ C. (M. Pt. of indium) and 197‹ C. (decomposition of glycol); 180‹ C. is suitable. The body is ntype germanium so that the application of two alloy regions produces a p-n-p transistor. Other metals that may be deposited are gallium, caesium, bismuth, or intermetallic compounds such as indium-cadmium. A higher boiling solvent such as glycerol may be used. Initial shaping of the body may be carried out independently, e.g. with a separate jet-etching system or by the method of Specification 805,291. Reference has been directed by the Comptroller to Specification 761,795.

Title: Improvements in arc voltage regulating circuits in consumable electrode welding
IPC: C08F2/00
Filed: 1954-12-14
Abstract: 772,896. Automatic arc welding control systems. SOC. L'AIR LIQUIDE, SOC. ANON. POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES G. CLAUDE. Dec. 14, 1954 [Dec. 18, 1953], No. 36229/54. Class 38 (4). [Also in Group XL (c)] In a D.C. arc welding system in which the electrode is fed by a non-reversible servomotor in accordance with the amplified difference between the arc voltage and a reference voltage, the gain of the amplifier is increased as the error signal increases. In one embodiment, Fig. 1, the voltage between the electrode 1 and workpiece 4 is opposed by a reference source 10. A portion of the resultant is tapped off at 7a and applied via an integrating network 13, 13a to control a triode 11 which forms part of the cathode load of a push-pull oscillator 19, 20 and so controls the amplitude of oscillation. The controlled output of the oscillator is rectified at 26 to provide a D.C. control signal to a thyratron control represented at 29 for a D.C. electrode feed motor 3. It is stated that hydraulic or pneumatic motors may replace the electric motor. To obtain the non-linear gain characteristic, the triode 11 is shunted by a triode 32 normally biased to cut-off, which conducts when the error signal increases beyond the cut-off point. In a second embodiment, Fig. 4, a portion of the arc voltage tapped off a potentiometer 73 is compared with a reference 76 and the resulting error signal is converted to A.C. by a synchronous vibrator 74. The A.C. error signal is amplified by a variable mu tetrode 54, the output of which is rectified at 65 and applied to the feed motor control 29. The tetrode 54 is biased by a battery 49 opposed by the output of a rectifier 55. This output is derived from a second vibrator 81 in accordance with the difference between a portion of the arc voltage tapped off a second potentiometer 73 and a second reference voltage 82. The gain of the amplifier is thus increased for signals which are above or below the value determined by the second reference source.

Filed: 1928-12-10
Abstract: 325,044. Lorenz, E. Dec. 10, 1928. Piles.-In making a concrete pile, a cavity is made below the lower end of the preparatory pile, and filled with concrete, forming a socle or base; during the boring and filling of the base-hole, a water pressure is maintained in it to prevent sand and earth from falling into the cavity. Preferably the cavity for the socle and the lower part of the pile is first filled with concrete, and the water is then pumped away before the remainder of the bore hole is filled with concrete. Fig. 4 shows an excavating tool comprising two resilient knives s, the ends of which are articulated to top and bottom plates r, w. The knives are forced into the form shown in dotted lines by pressing down the spindle u to a distance determinable by adjusting the stop q. The device may be provided with a bag, consisting of an approximately triangular piece of fabric, into which the excavated earth passes. This bag stretches between one of the knives s and the spindle u. The concrete is filled in by means of a bucket with a movable bottom, and is compressed by a ram operated under the water.
