Abstract: 525,462. Two-way transmission. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Feb. 21, 1939, No. 5816. Convention date, Feb. 22, 1938. [Class 40 (iv)] In a circuit involving a balancing network at the junction between a two-way and two one way lines, means are provided for measur ing the want of balance and for adjusting the network automatically or otherwise while the circuit is in use. The test currents which are applied to the receiving branch are picked up in the sending branch and measured or used to control the impedance of a valve acting as an element of the network or to control a regulating resistance by means of a motor or step-by-step switch. In the arrangement using a valve impedance the test current is applied continuously and is outside the range of the communication frequencies. The Figure shows an arrangement in which test currents from Up are prevented by the use of tapped transformers T1, T2, T3, T4 from reaching the two-way line. The degree of unbalance is represented by the difference between the test current voltages developed across resistances R1, R2. These may be filtered out, rectified separately and applied jointly to an indicating or controlling circuit. The regulators or rectifiers are preferably slow-acting. A known arrangement is referred to in which the balancing network is automatically adjusted on the occurrence of a disturbance of long duration.

[Also in Group XXVII] In a cooling liquid circuit for an internalcombustion engine 1, the operating temperature of a thermal element 4, regulating the cooling rate of the engine coolant, can be manually adjusted, or is adapted to be adjusted automatically in accordance with engine temperature, such that as the engine temperature decreases the relative temperature of the coolant is increased and vice versa and hence a predetermined optimum engine temperature is maintained. The element 4 may regulate the cooling rate of the engine coolant by largely preventing the flow of coolant through the engine or, as shown, by controlling the flow through a duct 9 by-passing the cooling radiator 2. The operating temperature of the element 4 may, for example, be controlled by a thermostat (e.g. 12, Fig. 7), located at some suitable point on the engine or in accordance with engine loading, exhaust gas temperature, ambient temperature conditions, throttle position, fuel supply, power output with respect to engine speed, or any other factor directly affecting the engine temperature. In Fig. 6, the control of thermal element 4 is effected through a toothed wheel 16 by the movement of the governor rod of 14 of injector pump 15. Operation of thermal element 4 may control in addition the radiator shutters (Fig. 8, not shown), and/or the speed of the cooling fan 19 (Fig. 7), either hydraulically through a fluid coupling 18 or by magnetic pneumatic or mechanical means. The coolant may operate under pressure.

Abstract: 1,021,859. Tunnel diode matrix stores. STANDARD TELEPHONES & CABLES Ltd. Feb. 15, 1963 [Feb. 20, 1962], No. 6261/63. Heading G4C. [Also in Division H3] A storage matrix is formed from storage cells (Fig. 7) comprising an ordinary diode 101 connected in parallel with a tunnel diode 102 to provide a load line which intersects the tunnel diode characteristic at two points (a and b, Fig. 2, not shown) so that the circuit has two stable operating conditions, a controlling circuit being connected in series with the tunnel diode arm of the circuit to effect switching. Switching from the high-voltage conditions b to the lowvoltage condition a in the circuit shown is effected by applying simultaneous half-amplitude pulses to lines 111-1 and 111-2 while resetting is effected by momentarily increasing the bias current to the circuit by rendering a transistor 108 conducting. Non-destructive read out may be effected by applying a halfamplitude pulse to winding 111-1 and simultaneously a pulse to gate 109. The former pulse has the effect of shifting the tunnel diode characteristic to the right. This moves the intersecting point a to the right but not the intersecting point b so that if the circuit is in state a an output pulse is produced which passes through the gate to output line c. Fig. 8 (not shown) illustrates a matrix of such circuits in which writing is effected by applying simultaneously pulses to one of the row inputs 11 and one of the column inputs 12 while resetting is effected by closing one of the switches A9, B9C9 &c. Non-destructive read-out is effected by applying a half-amplitude pulse to one of the rows simultaneously with a pulse to one of the output gates A6, B6, C6 &c. Writing may be effected in a parallel manner in which case the row pulses are applied simultaneously. Alternatively " writing " and " reading " may be effected sequentially. Checking of the correct operation may be effected since the writing pulse on the row is simultaneous with a pulse on the gating circuit so that the writing pulse and the gated pulse may be compared in a comparator to indicate the correct operation. When " reading," the gates select the columns from which the information is to be obtained.
