Filed: 1938-05-07
Abstract: 517,861. Directive wireless signalling. CLEVELAND, F. J. (Bendix Aviation Corporation). May 7, 1938, No. 13698. [Class 40 (v)] In order to remove the 180‹ ambiguity when taking bearings, the part of the indicator scale diametrically opposite the true critical reading is masked by a movable member. The invention is described as applied to a receiver of the kind described in Specification 517,862. The mask 44 fits over the dial 43, and comprises a cut-away portion 44b to expose a part only of the scale. It is set so that the " zero " 44c coincides with the index pointer when the frame is adjusted for maximum signal strength. When the frame is subsequently set to the critical " minimum " position, the true bearing can be read through a cut-away portion 44b of the mask, though the false minimum, diametrically opposite is screened from view.

Filed: 1967-03-28
Abstract: 1,167,244. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 28 March, 1967 [1 April, 1966], No. 14051/67. Heading H4P. A chain code is used for the transmission of digital data, the point of entry in the chain code being determined by the data. At the transmitter 3-bit input data words control the transmission of an 8 (=2<SP>3</SP>)-bit chain code. The 3-bit word is stored in an input register which feeds a gating arrangement which detects the presence of the binary number 000. An 8-bit output shift register contains the chain code and its output is fed back to its input. Pulses are supplied to the input register, each of which adds one to the number stored, until 000 is detected. The pulses necessary to bring the input register to this state also advance the output register and the bit-pattern contained in the register when advancing ends is that chain code pattern that is transmitted. The pattern transmitted thus depends not only on the input word but also on the pattern in the output register prior to advancing, i.e. on the last word transmitted. If the output register is reset to a preset pattern prior to advancing the pattern transmitted depends only on the input word. At the receiver the received word is compared with the output of a chain code register which is advanced n times until equality is reached. A preset number set in a 3-bit register is incremented by n, the resulting 3-bit number being that represented by the received chain code.

Abstract: 1,134,656. Semi-conductor devices. RADIO CORPORATION OF AMERICA. 31 March, 1966 [15 April, 1965], No. 14406/66. Heading H1K. In an insulated-gate FET comprising a body of single crystal bandgap material, the gate insulation comprises a crystalline material having an average atomic spacing between 0À9 and 1À1 times that of the body material. The insulator should have a conductance less than 10<SP>-3</SP> times that of the body and a bandgap of at least 1À1 eV. and at least 0À4 eV. greater than that of the body. N-type source and drain regions (25, 27) are produced in a wafer (23) of gallium arsenide by masking the surface and heating in sulphur vapour, Fig. 5B (not shown). The surface is then remasked and again heated in sulphur vapour to produce an N-type channel region (31), Fig. 5C (not shown). An epitaxial layer (29) of pure gallium phosphide is grown by a halogen or oxygen transport technique, Fig. 5D (not shown), and a degenerate gallium phosphide layer (33) is deposited by using a source heavily doped with tellurium or by adding sulphur to the hydrogen ambient. These two layers serve as the gate insulation and gate electrode respectively. The gallium phosphide layers are then masked and etched to expose parts of the source and drain regions which are contacted by means of lead wires or evaporated gold layers (35, 37), Fig. 5E (not shown). Gallium phosphide may also be used as the insulator on a silicon wafer, and gallium arsenide may be used as the insulator on wafers of germanium, indium arsenide and indium antimonide. The insulator may be polycrystalline. The body may be provided with a contact and biased with either D.C. or A.C., and if the body is thin and resistive an auxiliary gate electrode may be applied to the lower face of the wafer.

Abstract: 1486519 Identifying and counting coins NGZ GELDZAHLMASCHINEN GmbH & CO FERTIGUNGS-KG 9 April 1975 [19 April 1974] 14551/75 Headings G4V G4X and G4D Apparatus for identifying and counting coins comprises an optical signal transmitter controlling a counter in which the signal transmitter is formed by an optico-electronic image converter past which the coins are adapted to be guided and which supplies signals representative of the respective coin surfaces, the said signals being fed to a comparator which in its turn feeds the counter with signals associated with the coins. Coins are fed from a trough 13 to a rail 15 by conveyer 14. A rocker member 16 permits coins to pass to rail 18 when in a closed position but when open coins fall on to conveyer 17 and are passed back to the trough. Coins passing along the rail pass image converter 19 consisting of four solar cells 20. A light source 21 projects rays through a condenser 22 to the solar cells. From the rail coins pass through shoot 23 into distributor shoot 24 and thence into through one of passages 27 into a container 29. Shoot 24 is positioned by a step-by-step mechanism 26. Fig. 2 shows how rocker member 16 is rotated to an open position by magnet 38 when it receives a signal from photo-electric cell unit 36 via store 37, that a coin has passed. The member 16 is closed when the counting operation in respect of a coin is completed. When a coin passes image converter 19 there is a decrease in the output voltage of a summation or adding unit 39. If the value is below an adjustable reference level comparator 41 prepares for an evaluation instruction. This occurs when the solar cells 20c and 20d are covered by equally large amounts which causes zero-pasage discriminator 42 to pass from a low level to a high level position. After delivery of the evaluation instruction store 37 is returned to its initial position. Also by means of an eight-channel analogue comparator 43 and a coder 44, a channel number is fed into an intermediate store 45 when there is voltage parity between the output voltage of summation unit 39 and a reference level adjusted by reference level adjusting unit 31. The reference levels correspond to the normal dimensions of the coins of a coinage system. The channel numbers are supplied to a counter 46 which has a valuation stage, an adding mechanism 48, a store 49 and an indicating means 50. A metal senser 51 prevents the use of counterfeit coins. For coin sorting, the difference between a channel number which is stored in an intermediate store 45 and the counter content of a forward and backward counter 54 is determined in a comparator stage 53. Depending on the difference an instruction is given to control means 55 of mechanism 26.
