Abstract: 876,560. Tyre valve connectors. SHAW, A. E. June 10, 1960 [June 11, 1959], No. 19969/59. Class 99(1). Air pressures in pneumatic tyres are equalised or adjusted by means of an air line provided with three adaptors or valves, one of which is connected with an external source of air under pressure and the others are connected to the valves of the tyres. Fig. 5 shows tyres A, B connected to an air line, the adapter connected to tyre A being of the form shown in Fig. 3 and that connected to tyre B as shown in Fig. 6. In Fig. 3, the adaptor for a conventional tyre valve 10 comprises a spring-loaded valve 27, 28 which is operated to open the tyre valve when the rubber casing 23 is compressed to form an air tight joint by operation of the cam 29. The adapter of Fig. 6 is of the screw-on type and comprises a rubber casing 40 housing a spring- loaded valve 42 having a pin 45 which cooperates with the pin of the tyre valve. The valve connected in the air line is of the conventional type fitted on tyres and is operated by a valveless adapter, Fig. 7 (not shown), having a fixed peg which acts on the valve pin. Two such valveless adapters may be fitted at the ends of the air line for connection to the tyres in which case a stop tap is incorporated in the air line.

Title: Magnetic core buffer storage and conversion system

Abstract: 797,366. Electric digital-data-storage apparatus; electronic counting-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 11, 1955 [July 14, 1954], No. 19971/55. Class 106 (1). [Also in Group XXXIX] In a chain circuit in which a " one " condition is stepped along a chain of magnetic cores 26, Fig. 1, each carrying three windings, the transfer circuit between adjacent cores includes a discharge device (a thyratron 27) so arranged that when a core changes from its " one " state to its " zero " state as a result of an advance pulse applied to all the first windings of the cores, the discharge device is actuated to cause current flow in a winding of the next core, thereby setting the next core in its " one " state. In the apparatus described-a core matrix buffer store-the chain circuit is advanced by A-clock pulses of a utilization device and each thyratron (rendered self-extinguishing by a high anode load) as it fires to set a core to its " one " state also pulses a column of a core matrix already registering, as a pattern of " ones," the contents of a record card, thereby reading out the data in the column to a set of triggers 55 via pulse, amplifiers 51. The triggers 55 are reset by a B-clock pulse before the next A-clock pulse. Immediately before the matrix is read the first core of the chain is set to " one by camcontrolled contacts. The core matrix can also act as a code converter, for example as in Specification 746,724, which is referred to, in which the data is registered in the matrix on a " 1, 2, 4, 8 " code.

Title: Device for the limitation of the supply of continuous current to variable impedances
IPC: H02H9/02
Filed: 1974-05-07
Abstract: 1456751 Protective devices SOC ANON DE TELECOMMUNICATIONS 7 May 1974 [28 June 1973] 20079/74 Headings H2H and H2K A device for limiting the current flowing in a load supplied from a D.C. source includes two transistors connected in parallel controllable so as to have an increasing combined impedance as the load current tends to increase. If desired the transistors may be made non-conductive to disconnect the load from the supply should the overload persist for longer than a predetermined period. A load Z is connected across a D.C. supply Va, O, the line Va being connected to a distribution line Ve by way of a current limiting device having two transistors T 1 , T 2  arranged with their collector-emitter paths in parallel. A relatively low value resistor R 1  is connected between the line Ve and the common point of the collectors of the transistors T 1 , T 2  and a comparatively high value resistor R 2  connected between the line Va and the emitter of the transistor T 2 . During operation a high potential is applied to the base of transistor T 2  at terminal N so rendering the transistor fully conductive. The base of transistor T 1  is connected to the output of a differential amplifier A, the inputs to which are a fixed potential E and the voltage at the collectors of the transistors, i.e. the voltage Ve less the voltage dropped in the resistor R 1 . Under normal load conditions the inputs to the amplifier A are such that -its output is high. Thus transistor T 1  is fully conductive and the voltage Va is approximately equal to the voltage Ve. Should the voltage Ve rise to an unacceptable value or should the impedance of the load Z fall suddenly the inputs to the amplifier A become such that the output signal therefrom decreases whereupon the impedance of transistor T 1  increases thereby limiting the load current. In Fig. 3 each transistor T 1 , T 2  is provided with an amplifying transistor T 3 , T 4  respectively together with a control device C which is arranged to receive a signal from the output of the amplifier A such that when a low level signal indicating an overload has persisted for longer than a given period the device C produces an output signal which renders transistors T 4 , T 2  non- conductive. Since the low level output from the amplifier A has already rendered the transistors T 3 , T 1  non-conductive the load Z is de-energized. The device may be rendered operative or inoperative by the application of a positive or a negative signal at terminal M.

Abstract: 148,318. Huth Ges., Dr. E. F. Jan. 16, 1918, [Convention date]. Driving-gear for winding and paying-out apparatus; winches; brakes and retarding-apparatus; regulating and control-transmitting gear.- In a winch for winding a wireless aerial, particularly for use on aircraft, of the type in which the winding drum is connected to the power driving means, preferably an air-driven propeller, by means of a releasable clutch, the antenna on reaching its coiled-up condition releases the clutch and applies a brake, the release of which brake, when it is desired to unwind the antenna, is effected by a hand control which simultaneously holds the clutch disengaged. The propeller 5 is keyed to the shaft 4 on which is revolubly mounted the drum 8, one side of which ia provided with a toothed extension 10. The latter is connected through the gearing 12, 13, 14 with a toothed wheel 15 freely rotatable on the shaft 4 and having a projection provided with a conical recess 17. A conical clutch 8, which is movable longitudinally but is not revoluble on the shaft, is adapted to engage the recess 19 and rotate the drum 8. The clutch is disengaged by depressing the pin 30, which is coupled to a projection 28 on a slide 26. A roller 29 carried by a lever 21 is thereby moved from the recess 31 to the recess 32 on the projection 28 and the lever 21 swung outwards, moving with it and disengaging the clutch 18 to which it is keyed by means of the pins 23, 24, and at the same time releasing a band brake 35 which is applied to the drum 8. To wind the aerial the pin 30 is raised by means of a Bowden wire hand control, to transfer the roller 29 to the recess 31 and engage the clutch, and the drum 8 is rotated by the propeller 5. When the aerial is fully wound, a collar 41 is pressed by the catch 42 on the aerial against a lever 38, which operates the lever 21 to disengage the clutch. At the same time the band-brake 35 is applied to prevent further rotation. The brake is so connected with the pin 30 that when, for the purpose of again unwinding the antenna, the pin 30 is depressed by the Bowden hand control, the brake is released and the clutch held disengaged. To prevent the toorapid rotation of the drum a centrifugal brake is fitted, consisting of weights 47 and friction blocks 48 pivoted to the drum 8. When the revolutions exceed a predetermined number. the blocks 48 overcome the action of the controlling springs and contact with a track 51 on the cover.
