Title: Improvements in underground motor vehicle garages
IPC: E04H6/40
Filed: 1952-09-26
Abstract: 728,372. Garages. LINN, W.H. Sept. 17, 1953 [Sept. 26, 1952], No. 24161/52. Drawings to Specification. Class 20 (1). An underground garage has at least one inclined ramp leading into it from ground level, and a plurality, e.g. six, of concentric, circular, rotatable platforms for accommodating vehicles and communicating with the ramp. Four entrances are described, vehicles passing over stationary platforms to reach the platform in question which is rotated to bring a vacant space opposite the entrance to receive the vehicle, the platform then being returned. The platforms run on rails and are mechanically driven, e.g. by independent motors. A central tower supports a dome-shaped roof and acts as a ventillation shaft. A pedestrian surround has corridors and arcades and leading to cafes, airraid shelters and other rooms. The ramps may curve round the exterior of the building to save space.

Title: Improvements in or relating to semi-conductive devices
IPC: H01L21/18
Filed: 1955-08-23
Abstract: 820,621. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 23, 1955 [Aug. 26, 1954; March 10, 1955], No. 24249/55. Class 37. In a method of making PN junction devices comprising applying a layer containing activator impurity characteristic of one conductivity type to a semi-conductor of the opposite type, heating to alloy it with the body to form a junction therein and afterwards cooling, the layer is contacted during alloying and cooling by a member having a linear expansion coefficient not more than twice that of the semi-conductor so arranged that the layer thickness is less than 0.01 mm. Where Si or Ge is.the semi-conductor a member of Mb, Cr, Wo or Fernico may be used, or the member may also be of Si or Ge. In one embodiment (Fig. 6) a Au-plated Wo disc 43 welded to a Ni-Fe wire 44, a 25Á thick Au disc 45, 100 Á thick N-type Si disc 46, 25 Á thick A1 disc 47 and a disc 48 of sintered Wo impregnated with A1 containing 1% Si are stacked in graphite block 40 under the pressure (preferably spring-assisted) of graphite weight 50 and heated for 15 minutes at 750 C. in an atmosphere of 80% N 2 : 20%H 2  to fuse the parts together. The assembly is then removed and etched in a mixture of acetic, nitric and hydrofluoric acids. A transistor (Fig. 5) comprises an In layer 31 between N-type Ge wafer 30 and gold-plated molybdenum member 32, which forms the collector connection, an In emitter block 34 alloyed to the other face of the wafer, and a Fernico wire 35 bent into the form of a circle preferably located in a groove 37. The wire is coated with an alloy of Au, Ge and Sb which is fused to make a base connection to the wafer. If a P-type Ge body is used In is replaced by a Pb: Sb alloy and the wire coated with an alloy of the Au, Ge and Zn. In a further embodiment a layer of A1 is fused between two N-type Si bodies to form junctions in both, one of the bodies then being removed by etching or grinding. If low resistivity P-type Si is used for one of the bodies only one junction is formed and the removal is unnecessary. As a modification of this a Au: As alloy is fused between a P-type Ge or Si body and a low resistivity N-type Si body. The member of selected expansion coefficient may be formed as or attached to a cooling member.

Abstract: 964,255. Frequency controlled circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. July 2, 1962 [July 7, 1961], No. 24605/61. Heading H3A. In an inverter circuit for supplying alternating current to a resonant load circuit connected across terminals A, B, means are provided for altering the frequency of operation of the circuit when a change occurs in the load impedance to maintain the frequency of the supply at resonance with the load circuit. The D.C. supply is converted to A.C. by a controlled rectifier TR1 and the output developed across terminals A, B is also applied via transformer T1 to a first phase-shifting circuit comprising C1, R1 which provides across points C, D and E, D a voltage shifted in phase from that appearing at terminals A, B. The voltage across C, D is applied to a second phase-shifting circuit R2, C2, R3, C3 and the negative halfcycles of the output of this circuit (positive half-cycles removed by rectifier Dl) are applied to point E where they combine with the output of the first circuit to provide a waveform with positive portions of duration shorter than a half-cycle and subsequent long duration negative portions. The positive portions cut-off transistors S1, S2, and during this period the rectifier TR1 is triggered from the positive voltage source G. During the negative portions of each cycle transistors S1, S2 are conducting and connect point H to the negative supply terminal F and during this period the rectifier TR1 is rendered non-conducting by the resonant action of the load. Alterations in the resonant frequency of the load advances or retards the positive portions of the derived waveform which trigger the rectifier and hence bring the supply frequency into agreement with the resonant frequency of the load.
