IPC: B65H20/12

Abstract: 962, 505. Pneumatic tape capstans. SPERRY RAND CORPORATION. July 5, 1962 [July 17, 1961], No. 25861/62. Heading G5R. [Also in Division B6] A pneumatic capstan roller for selectively engaging a record tape, 12, has a housing 24 including a fluid conduit having an inlet 52, a throat 30 and an exit 32, the throat being enlarged with respect to the inlet at their function, and at least one passageway 36 connecting the throat with the periphery of the capstan roller. The velocity of fluid, e.g. air, flowing in the conduit is controlled by position of a plate 38, such that if the velocity in the throat section is high there is a partial vacuum at the capstan roller periphery to cause engagement of the tape and capstan roller and if the velocity is low pressure is created at the periphery of the tape carrier to disengage the tape from the roller. The position of the plate 38 is controlled by a coil 46 within a polepiece 48, the coil being energized by conductors, not shown, in a channel 50. The plate 38 is held away from an exit 54 by springs 60 which oppose the force of the fluid when a small current is supplied to the coil 46. When this current is increased the plate 38 is attracted to move the plate to "closed position". A reduction of the current causes the plate to be returned to "normal position", while complete de-energization of the coil allows the plate to move to "open position". In another embodiment Fig. 6 (not shown) a movable plate 72 is positioned adjacent an inlet channel 70 which extends into the fluid conduit at a point A, such that the pressure at this point may be varied by the position of the plate 72.

Abstract: 1,193,532. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 8 Jan., 1968 [13 Jan., 1967], No. 1001/68. Heading H1K. [Also in Division C7] Electrical contact is made to a semi-conductor region with an impurity concentration of at least 1018 atoms cm.<SP>-3</SP> by depositing first a film of chromium, aluminium or titanium and then a film of nickel, silver, copper or copper chromium alloy. In one embodiment an antimony-doped N+type silicon wafer carrying an epitaxial N type layer is first provided with a silicon oxide coating by heating in dry oxygen and then in steam, or by R.F. sputtering, or with a layer of silicon nitride or alumina. Base and emitter regions are then formed by successive diffusions of boron and phosphorus into the N layer using standard planar techniques, the second diffusion doping the emitter and collector contact region with 5 Î 10<SP>20</SP> atoms/c.c. of phosphorus. Aluminium base and emitter contacts are next provided by vapour deposition overall followed by form-etching and sintering. Glass is subsequently deposited over the contacted face of the wafer in two stages of R.F. sputtering each followed by a firing stage. The wafer is then inverted in an evacuated vapour deposition chamber and its back collector contact face coated with successive layers of chromium, copper and gold of specified thickness while the wafer is held at 200-250 C. Holes are next etched through the glass layer to expose the aluminium contacts upon which similar layers of Cr, Cu and Au are then deposited through masks followed by layers of lead-tin solder by means of which nickel-plated copper balls are attached to the contacts. Finally the completed elements are attached to silver palladium lands on an alumina mounting plate and the ball contacts connected via nickel-plated copper strips to adjacent lands using lead-tin solder. In alternative planar diode and transistor embodiments the outer layer of gold is omitted.

Title: Improvements in electrical regulator systems
IPC: B60L1/00
Filed: 1926-01-13
Abstract: 266,103. Filmer, C., and Metropolitan- Vickers Electrical Co., Ltd. Jan. 13, 1926. Boosting.- A voltage regulating system comprises a booster 39 and an exciter 29 driven by a motor 17 from the variable voltage supply 13, 15, the booster being excited in accordance with the difference between the voltages of exciter and supply and the motor having a different voltage-speed characteristic from that of the exciter. Preferably the motor has an unsaturated magnetic circuit whilst the exciter operates at a higher degree of saturation. Thus the speed of the motor and the voltage of the exciter change at a lower rate than the supply voltages. The speed of the motor or the shunt field of the exciter is adjusted so that the exciter and supply voltages balance at normal voltage and the boosters is thus reversibly excited by fluctuations above and below this value. The booster is preferably unsaturated so that its voltage varies as its excitation. Various arrangements of shunt and compound windings on the different machines are suggested in the Specification. This motor may have a resistance 23 permanently in series to enable it to be connected to the circuit without starting devices. The machines 29, 39 may have a common yoke.

Abstract: 559,411. Electric selectors. STANDARD TELEPHONES & CABLES, Ltd. Jan. 26, 1943, No. 1284. Convention date, Feb. 5, 1942. [Class 40 (iv)] [Also in Group XXXVII] In an electromagnetically-operated step-bystep switch, the contact-carrying ratchet wheel 1 is of thin steel and of large diameter and guided near its periphery by passing between a narrowed portion 21 of a groove 20 extending round a semicircular insulating member 14 carrying the fixed contacts 11. In the form shown there are thirteen groups of fixed contacts, each group comprising contacts such as 12, 13, 17, 18 moulded in the member 14 and engaged by long and short wipers 5, 6 on four brushes mounted at diametrically opposite points on each side of the wheel 1. The ratchet wheel 1 is loosely mounted on a constantly rotating shaft 22 which tends to drive it counter-clockwise (Fig. 3) through the medium of a friction clutch comprising two elements 24, 28 pressed towards each other by a spring 30 and longitudinally movable relative to the shaft, felt washers 27 and a metal washer 26 which forms a seating for the wheel 1 being arranged as shown. The ratchet wheel 1 is normally held against rotation by the tooth 43 of an escapement pawl, but moves forward so that the next group of contacts is engaged each time an electromagnet is energized. On de-energization, a small further movement takes place but not enough to break contact. A number of ratchet wheel units may be mounted on the same shaft 22, the frames 49 of the magnets 45 being also mounted on a common shaft so that when two release magnets 65 are energized, their armatures 68 will tilt all the frames 49 so that the pawls are withdrawn from the ratchet wheels whereupon these rotate till projections 74 on them engage stops 66 which have been simultaneously moved into position. On de-energization of magnets 65, the pawls re-engage their ratchet wheels which are thus all set in their starting position.
