Title: Auxiliary drive for reversible power machinery
IPC: F01B17/04
Filed: 1938-05-26
Abstract: 515,166. Power plant. HASENCLEVER, E. May 26, 1938, No. 15692. [Classes 110 (iii) and 122 (iii)] [Also in Groups XXXIII and XXVII] Power plant wherein one or more auxiliary machines are driven from a reversible main engine during normal forward operation of the engine and wherein during reversal or stoppage of the main engine the auxiliary machine is driven from an axial shaft by one or more auxiliary engines or by the main engine itself through suitable gearing. The installation is characterised in that the drive from the main engine is through a free wheel clutch and the other drive is either through an ordinary clutch or a free wheel clutch of opposite hand. The internal combustion engine 1 drives through a chair gear 4 and free wheel clutch 5 an auxiliary machine 2 which is further connected by a free wheel clutch 6 of an opposite hand with an auxiliary engine 3. When the engine 1 is controlled so as to change from a forward to stop or reverse running, the auxiliary engine 3 may be brought into operation automatically by connecting this control through suitable gearing 7 with the control of the main engine. The starting of the auxiliary engine may be effected when the revolutions of the main engine fall below a certain value. In another form the engine drives through gearing 3 and a coupling 11 which may be a spring or fluid coupling, a shaft carrying gear wheels 5 and 6. The auxiliary machine 2 which may be a blower has upon it shaft 9, gear wheels 7 and 8 in the hub of which are disposed opposite handed free wheel devices. Gear wheel 7 gears directly with 5 whilst the gear wheel 8, obtains a reverse motion from 6 through an intermediate pinion 10. When the main plant is going ahead the drive is through pinions 5, 7 when the engine 1 is reversed the drive is through pinions 6 and 8. Where the auxiliary machine 2 is liable for use when the main engine is stationary, then the shaft 9 may be continued and coupled to an auxiliary engine. In a modification, in place of an internal combustion engine a turbine or reciprocating steam engine may be used and in that case the auxiliary engine may then be a steam engine, and in addition upon the shaft may be other units such as dynamos and circulating pumps. In another modification, where a steam plant of reciprocating and exhaust turbine is employed and where the turbine drives through a double reduction gear, then the drive for the auxiliary machine may be taken off the intermediate shaft of the double reduction gear. Where also a multiple turbine installation is used the drive from the main engine may be taken from any one of the shafts in the geared drive.

Title: Process for treating semiconductors
IPC: H01L23/535
Filed: 1961-05-04
Abstract: 908,553. Semi-conductor devices. WESTING- HOUSE ELECTRIC CORPORATION. May 4, 1961 [June 22, 1960], No. 16205/61. Class 37. A low-resistance path is formed between two areas on the surface of a body of semi-conductor material by applying a metal layer over each area, contacting each layer with a probe, and discharging a capacitor through the layers and the region of the body lying between them, the initial charge of the capacitor being such that the semi-conductor material in the vicinity of the path of the discharge is melted. The semiconductor material may be Si, Ge, SiC, a III-V compound, e.g. InSb, InAs, GaSb, GaAs, GaP, or a II-VI compound, e.g. ZnS, ZnTe, ZnSe, and may be intrinsic or wholly or partly of P or N-type conductivity; the invention is particularly applicable to semi-conductor bodies forming unitary multifunctional devices. The capacitance of the capacitor and the charge placed upon it depend upon the semi-conductor material, its thickness, and the composition of the metal layers; for Si wafers 1-10 mils. thick a capacitance of 500-2000 ÁF. may be charged to 8-20 v. for a metal area of about 100 sq. mils. As shown, Fig. 2, foils 20, 22 comprising 99.5% Au, 0.5% Sb, are disposed centrally on opposite faces of a monocrystalline Si wafer 10 1.4 mils. thick having a P-type region 12 and an N-type region 14, and are fused thereto at about 700‹ C. in a vacuum of 10<SP>-5</SP> mm. Hg. When cool, the foils 20, 22 are contacted by probes 32, 34 and a 900 ÁF. capacitor which has been charged to a level of 10 v. is discharged through the probes, the layer, and the wafer. This causes local melting of the wafer; the metal layer may also melt locally, or the molten Si may dissolve some metal. On cooling and recrystallization, a region 70, Fig. 4, of low resistance is formed between the foils, the PN junction 16 being destroyed within this region. A region of low resistance may be formed similarly between two areas on the same face of a semi-conductor wafer. Fig. 3 shows an arrangement comprising a double-throw switch 56 whereby a capacitor 40 can be alternately charged from a voltage divider 52 and discharged through leads 36, 38 which are connected to the probes which may be of steel or a Cu base, e.g. Cu-W, alloy. The metal layers may alternatively comprise A1, and may be in pellet form, or may be plated or vapour deposited on to the wafer.
