Patent GB-898844-A (GB)
Title: Electronic switching systems
IPC: H03K17/81
Filed: 1958-12-19
Abstract: 898,844. Automatic exchange systems; magnetic storage apparatus. STANDARD TELEPHONES & CABLES Ltd. Dec. 19, 1958 [Dec. 27, 1957], No. 41149/58. Classes 40 (4) and 40 (9). In a switching matrix consisting of gates, a selected gate is opened, and maintained so for the duration of a connection to be extended therethrough, by pulsing a condenser associated with that gate once per cycle, the time constant of the discharge path of the condenser being such that the potential difference across the condenser remains sufficient to keep the gate open until the condenser is recharged by the next pulse. Each gate, of which only one is shown in Fig. 2, consists of a symmetrical transistor Ghk having its base normally brought to a positive potential via RAhk and RBhk to cut off the transistor, the other two electrodes of which are connected to a line Lh and a junction Jk, respectively. The transistor is rendered conductive by charging Chk as described below. The control circuit for a matrix of twelve gates is shown in Fig. 1. A pulse generator GC feeds a counter consisting of three bi-stable circuits C1, C2, C3 which delivers binary outputs to a decoding circuit MD1 having outputs d11, d12, d13 corresponding to three junctions and a fourth output d14 controlling amplifier A, which outputs are energized cyclically. A memory M, of bi-stable magnetic circuits, has a store for each of the three junctions and the setting up of a connection is initiated by causing the memory control circuit CE to write in the store of the relevant junction the identity of the line to be connected thereto. When the output corresponding to that junction is energized by MD1 the line identity is transferred to the bi-stable circuits BS1, BS2 as a result of which the decoding circuit MD2 energizes the lead of d21 to d24 corresponding to that line. Associated with each gate in the matrix is a core such as Thk (Fig. 2) these cores being arranged in a matrix having four rows Ra1 to Ra4 and three columns CO1 to CO3 (Fig. 1). The core at the intersection of the row and column corresponding to the line and junction to be interconnected receives both row and column pulses and is thus switched from the normal " 0 " state to the " 1 " state. BS1 and BS2 are restored by the pulse repeater GR, and at the end of the cycle the pulse on d14 is applied to all the cores and restores those in the " 1 " state to the " 0 " state. In such a core an output pulse appears in winding C (Fig. 2) in such a direction that rectifier Dhk has a low impedance, and the potential at the junction of RAhk, RBhk goes negative. Capacitor Chk is charged quickly by this output pulse and the time constant of Chk, RAhk is such that the base of Ghk remains sufficiently negative to maintain it conductive until the next output pulse is received from the core. Capacitor Chk is recharged at the end of each cycle for as long as the line identity remains written in the memory M.

Abstract: 930,729. Tractor power lift RHEINSTAHL HANOMAG A.G. Dec. 5, 1959, No. 41384/59. Class 79(1). In a tractor power lift mechanism, the spring loading in a pressure relief valve is controlled by a depth-responsive member so as to obtain depth control. The implement 29 is attached to the suspension links 3, 5 which are operated through the lift arms 8 by the ram 10, pressure fluid from a reservoir 15 being supplied by a pump 14 through line 17. The implement may be raised and lowered under the control of a manually operated valve 16. A spring loaded valve 18 is incorporated in the pressure supply line 17 and comprises a spring 23 the loading which can be varied by a cam 27, by a lever 26. A pair of wheels 31 are carried by a shaft 32 mounted on a lever 33 pivoted at 35 to a rod 36 carried by the implement supporting member 30 and the height of which is adjustable by a handle 38. A flexible cable 40 is connected by a universal joint at 39 to the lever 33 and by a member 43 to the lever 26. For a given working position, the valve 18 is first set manually, and thereafter the valve is operated in response to changes of ground level fluctuation through the flexible cable 40. In a modification, Fig. 5, the spring 23 of pressure relief valve 18 is controlled by a lever 60 engageable in different positions with notches 62 in a quadrant. The flexible cable 40 is provided with fixed stops between which are located plates 65 and a compression spring 64. The lever is normally moved by the flexible cable but manual control is obtained by over-riding the pressure of the spring 64. In a further embodiment, Fig. 6, the flexible cable is replaced by a hydraulic system having operating pistons 67 and a pressure compensating member 74. In the embodiment of Fig. 5 the feeler member is mounted for vertical movement against the action of a spring 69.

Abstract: 1486798 Transistor stores SIEMENS AG 27 Sept 1974 [28 Sept 1973] 42026/74 Heading H3T A storage circuit comprises a pair of complementary field effect transistors 1, 2 connected in series with a load 3, at least one of the transistors, 2, being a depletion type and having its gate electrode connected to the drain electrode of the other transistor 1. With small voltages across nodes 26, 36 the impedance of transistor 2 is low compared with that of transistor 19 the current/voltage characteristic Fig. 6 (not shown) is initially governed by that of transistor 1. As the voltage increases to saturate transistor 1, transistor 2 becomes almost cut off, and the current falls to a very low value. The circuit can thus operate in a bi-stable mode. The load 3 may be a further depletion type FET and the transistor 2 may be either an enhancement type with its gate connected to line 5 as shown, or a depletion type with its gate connected to line 6. Read out gate 4 may be either a diode or a further enhancement FET. To read out, a small amplitude pulse is applied to line 6 and to write in a large amplitude pulse of opposite polarity is applied to line 6 to set the circuit to one of its states. This is then followed by a pulse of the same polarity as a "read" pulse, but of larger amplitude, together with a data pulse on line 8, Fig. 7 (not shown).

Convention date, Aug. 8, 1933. [Classes 7 (ii) and 7 (vi)] In a two - stroke engine with exhaust ports in the cylinder head and piston-controlled air-inlet ports at the other end of the cylinder, means are provided for delaying the supply of air to the inlet ports until after the piston has uncovered a substantial area of the inlet ports, so as to obtain a more even scavenging action. Fig. 1 shows exhaust valves 5, of which there may be four, in the cylinder head, and air-inlet ports 10 to which air is supplied past valves 11 which open automatically or by positive operation after the piston uncovers the ports 10. Adjustable baffles 15 are arranged between the valves 11 and the ports 10 nearest thereto, so as to equalize the flow of air. The closing of the exhaust valves may occur before or after the closing of the ports 10 by the piston. Fig. 6 shows another construction, in which tangential air ports 18 are supplied from a valved pipe 11, the flow of air being equalized by a baffle 16 formed with ports 17 and tips 20 hinged at 21.
