Title: Improvements in or relating to electrical conductance standards
Inventor: CALVERT RAYMOND
IPC: H03H11/18
Filed: 1964-06-12
Abstract: 1,037,924. Phase shifting. WAYNE KERR LABORATORIES Ltd. June 8, 1965 [June 12, 1964], No. 24581/64. Heading H2F. [Also in Division G1] A phase shifter includes a quadrature phase shifting circuit 14 comprising an operational amplifier 25 and capacitor 26 which is switchable by means of the switches 28 and 29 to give alternatively a phase lead or a phase lag of 90 degrees, a source of A.C. 10 and a transformer 12 by means of which an alternating voltage is applied to the phase shifting circuit, an output circuit including a transformer 17 and detector 19 by means of which the outputs from the phase shifting circuit in the two alternative switchable conditions are compared and a resistor 27 for adjusting the overall gain of the phase shifting circuit. The phase shifting circuit 14 is used in conjunction with a capacitor 15 to set up a conductance (or resistance) standard. The circuit is used to phase shift the supply to the capacitor by exactly 90 degrees, so that the combination of phase shifting circuit and capacitor does not shift the phase of the supply at all, and appears to be purely resistive. It is necessary for the gain of the phase shifting circuit to be exactly unity, and this is achieved by adjusting the resistor R until no change in the output to the meter 19 is recorded when the switches 28, 29 are set in their alternative positions. The capacitor 15 is arranged in a bridge circuit which has an adjustable resistor G s  in an opposite arm. This resistor is adjusted until zero output from the bridge is recorded (again on the detector 19). The value of the resistor then corresponds to that conductance determined from the value of the capacitor C s .

Abstract: 1,090,223. Feeding sheets. SINGER CO. June 11, 1965 [June 15, 1964], No. 24683/65. Heading B6B. [Also in Division D1] Fabric sheets, which are to be guided so that one edge moves along a straight line XX, are placed singly between two spaced plates 21, 22 so that the edge of a sheet engages a face 25 on an upturned portion 24 of the plate 22, and the sheet is maintained against the face 25 by compressed-air from a system of nozzles. The top plate 21 has nozzles 30, 31 secured over apertures therein and inclined in the direction in which the fabric sheet travels, and a nozzle 36 which is oppositely inclined. A further nozzle 35 is secured over an aperture in the plate 21 normal thereto, and is directly opposite the mouth 34 of an air nozzle 33 in the bottom plate 22. The nozzles 30, 33 are connected together by a hose 32; the nozzle 31 is connected through a hose 37 to a source of compressed-air; and the nozzles 35, 36 are connected by hoses 40, 38 and a connection 39 to a common hose 41 leading to the source of compressed-air. In operation, if the edge of the fabric sheet moves away from the line XX, it uncovers the mouth 34, allows compressed-air to pass from the nozzle 35 to the nozzle 33, and through the hose 32 to the nozzle 30, so that the fabric sheet is subjected to a further force which urges it back towards the line XX, and the face 25. The face 25 acts as a deterrent against excessive movement of a sheet to the right. As described, the invention is applied to a sewing-machine.

Abstract: 1294504 Semiconductor devices RCA CORPORATION 26 May 1970 [5 June 1969] 25161/70 Heading H1K A transistor is made by forming the base region by diffusion in an oxiding atmosphere to provide an oxide layer, forming a phisphosilicate glass layer over the oxide and forming a protective coating over the glass, and opening a window in the oxide, glass and protective layer for the emitter diffusion. A P type Si wafer 14 having an N+ type surface layer 16 is provided with an N type layer 18 by epitaxial growth. An SiO 2  layer 22 is produced by oxidation, a window is formed and B is predeposited in an oxidizing atmosphere. The borosilicate glass layer formed on the surface is removed and the water is heated in steam to drive in the B to form the P type base region and to form an oxide layer (28) in the window. The base diffusion is stopped before the finally required depth is achieved. A layer 30 of phosphosilicate glass is formed over the oxide layer 22, (28) either by heating in an atmosphere of phosphorous and oxygen or by pyrolysis of silane and phosphine. A further SiO 2  layer 32 is formed on top of the glass layer 30 by heating in an atmosphere of silane and oxygen followed by annealing in steam to densify the oxide and to complete the base diffusion. Openings are then formed in the insulating layers to expose the emitter and collector contact sites and the wafer is heated in an atmosphere of phosphorus and oxygen to form heavily doped N type emitter region 42 and collector contact region 40. The phosphosilicate glass formed during this step is removed, a base contact window 44 is opened and collector, base and emitter electrodes 46, 48, 50 are applied.
