Filed: 1975-10-23
Abstract: 1512700 Data transmission STANDARD TELEPHONES & CABLES Ltd 19 Oct 1976 [23 Oct 1975] 43564/75 Heading H4P A p.c.m. data bit stream is combined {modulo-2 addition} with a pseudo-random bit stream and transmitted in an alternate mark inversion (AMI) code, framing, and possibly other out-of-band information being conveyed by violations of the rule that alternate bits which would normally be mutually inverted are not inverted. In an 8-bit byte format, the violations relating to the first bit carrying framing information, some, or all of the remaining bits may be associated with violations to carry signalling and other information. Coding and decoding arrangements are disclosed.

Title: Improvements in or relating to electrical circuits for scintillation counting
Inventor: CROSS ALAN CLARK
IPC: G01T1/208

Abstract: 917,046. Photomultiplier circuits. PLESSEY CO. Ltd. Nov. 16, 1961 [Dec. 19, 1960], No. 43610/60. Class 40 (3). A tunnel diode 2, Fig. 3, having the current/ voltage characteristic shown in Fig. 2, forms at least part of the anode load of a photomultiplier tube 1 used for detecting the radiation produced by one or more scintillation detectors on bombardment by nuclear particles or radiation, to produce fast response pulses and enable pulses corresponding to particles arriving nearly simultaneously at the detectors to be separated out. Variable resistance 3 gives a bias current IB through the diode which is connected to a transistor 5, such that a no-pulse current at the anode, between IB and Is gives a non- saturating base/emitter voltage less than VA, whilst a pulse current greater than Is jumps the base/emitter voltage to a saturation voltage greater than VB. In an alternative embodiment, Fig. 4 (not shown), a primary winding of a transformer is connected in series in the anode circuit of the tube, whilst the tunnel diode is connected across the secondary winding of the transformer. The transformer may be such that the anode current pulses are differentiated with respect to time.

A cord passes over the pulley and to the dashboard of the vehicle from where the opening and closing of the filler tube is controlled. The lever 11 may pass beyond top dead centre to prevent opening of the stopper from outside the vehicle.

Abstract: 441,709. Copying images on lenticular film. OPTICOLOR AKT.-GES., Glarus, Switzerland. Aug. 28, 1934, No. 24771. Convention date, Sept. 1, 1933. Addition to 421,084 and 435,859. [Class 98 (ii)] In copying from a lenticular film onto a lenticular blank film by projection with change of scale, the arrangement as described in Specification 435,859 is modified by the use of a different number of oscillating plane reflecting surfaces on opposite sides of the copying objective, the amplitude of all oscillating means being the same. The oscillating means are preferably angular mirrors and are connected together and, in copying with a ratio m n, the ratio of the number of angular mirrors on opposite sides of the objective is m : n. The Figure shows an arrangement for copying from a film 1 onto a film 13 with enlargement in the ratio 1 :2. Light from the original 1 passes by way of the mirrors 4, 5, 6 to the objective 2 and by the mirrors 7 ... 12 to the copy film 13, the mirrors 4, 6, 9, 11 being connected together and oscillated as a unit. In further forms, sets of fixed and oscillating angular mirrors are arranged on opposite sides of the objective. A diaphragm with an aperture in the form of a slit at right angles to the apparent movement of the images, or a punctiform aperture may be used in the objective. The Specification as open to inspection under Sect. 91 describes also a form in which a single moving angular mirror is employed, the film gate of the original performing a corresponding oscillation. This subject-matter does not appear in the Specification as accepted.

Abstract: 994,966. Measuring electrically. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 15, 1962 [Dec. 29, 1960], No. 44606/60. Heading G1N. Apparatus for determining the position of a movable body consists of a bi-stable circuit triggered to one state by constant phase pulses and to the other state by pulses whose phase is controlled in accordance with the position of the body, means for applying pulses corresponding to the position of the variable edge of the square wave produced by the bi-stable circuit to a gating circuit, and means for opening (or closing) the gate for time periods whose phase limits correspond to the specified limits of travel of the movable body so that the variable phase pulses are passed (or blocked) if the body is within the specified limits. Pulses passed by the gate are applied to indicating and/or control devices. The output from the gate preferably triggers a monostable circuit giving a substantially continuous output so long as pulses are passed by the gate. The output may be applied to a lamp or a relay. Alternatively a bi-stable circuit, reset by slightly advanced pulses from the variable phase signal source may be used in the output circuit. In another modification the gate connects the output from the first bi-stable circuit to a bypass circuit when the body is made (or outside) the limits. Automatic control action may be provided.

Title: Rotary Sliding Vane Compressor

Filed: 1968-09-20
Abstract: 1,189,937. Rotary sliding vane compressor. WORTHINGTON CORP. Sept. 20, 1968 [Oct. 23, 1967], No.44813/68. Heading F1F. A rotary sliding vane compressor having a working chamber 46 of substantially elliptical cross-section, end members closing the chamber, a rotor 10 concentrically mounted for rotation in the chamber having a plurality of radial longitudinally extending vane slots 22 slidably mounting vanes 20 and angularly spaced inlet ports 40 and outlet ports 38, includes an annular groove 26 in at least one end member (both as disclosed), communicating with the compressor inlet and the vane slots. The groove 26 has its inner side located at a radial position between the fully retracted and fully extended positions of the inside ends of the vanes whereby chambers defined behind the vanes will be closed to form gas pockets as the vanes are pushed inwardly so that the compressor gas acts as a spring to maintain contact between the vanes and the working chamber wall. At position A the vane 20 is in its fully extended position with gas being sucked into the working chamber and the inner end of the vane subjected to inlet pressure so that the vane is maintained in contact with the chamber wall solely by centrifugal force. As the vane moves to position C it is urged inwardly by the chamber profile in opposition to centrifugal force, vane inertia and suction pressure in the vane slot. On moving beyond position C to position D the vane slot is closed and the gas trapped in the slot is compressed and exerts pressure on the underside of the vane to urge the vane outwardly of its slot. Arcuate grooves 36, 34 in the end members inter-connect the slots between the positions D and B to prevent excessive pressure building up in a slot. In moving from B to F centrifugal force alone may not be sufficient to overcome inertia and friction to maintain contact between the vane and chamber wall, the gas pressure will then urge the vane outwardly so that contact is not lost.
