Title: Fouling protection circuit arrangements for railway signalling systems
IPC: B61L19/06
Filed: 1962-01-11
Abstract: 989,892. Fouling protection. STANDARD TELEPHONES & CABLES Ltd. Jan. 11, 1962 [Jan. 12, 1961], No. 1082/62. Heading B7N. In a fouling protection arrangement for a railway signalling system in which the layout of the signalling circuits corresponds to the layout of the track elements, a static fouling protection circuit setting element, e.g. a transistor or transductor, is provided in each electrical link corresponding to the track leading to each track element and one terminal of the fouling protection search signal source is connected to the junction of the setting elements associated with each track element. If fouling protection is sought from the direction 1 in the layout shown in Fig. 4, a negative voltage appears at input terminal e1, since the illustrated points cannot provide protection for this condition the search is extended in the directions 2 and 3 by the transistor circuit shown which when terminal e1 is negative produces a negative voltage at output terminals a2, a3. A search signal arriving at terminal a3 requesting protection from the direction 3 switches the voltage at FSR from negative to positive whereby the points are set to their right hand position to provide the necessary protection. Similarly the points are set to the left when a search signal arrives at terminal e2 from direction 2.

Filed: 1961-01-11
Abstract: 1,015,983. Alarm systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 11, 1962 [Jan. 11, 1961], No. 1197/61. Heading G4N. Safety apparatus, particularly for nuclear reactors, comprises a plurality of pairs a, b of test devices located at different test points in the plant and adapted to be connected successively over a line A, B to a comparator and to a combining unit. The devices of each pair are located together in a common zone so that they are responsive to the same conditions, e.g. temperature. Should the outputs from the test devices of any pair differ appreciably, due, e.g. to a fault in one of them, the comparator unit produces an output to operate a "warning" alarm 2 but if the outputs of both devices of a pair correspond to " danger " the combining unit output exceeds a predetermined value and operates a " danger " alarm 1. The various test points are connected to the line successively by pairs of gates GIA-GIB, G2A-G2B &c. The test devices may give an output signal only when danger conditions arise or they may normally give an output which is interrupted if danger conditions arise.

Title: Arrangement for measuring distance travelled by rail-mounted wheeled vehicle
IPC: G01C22/02
Filed: 1975-01-10
Abstract: 1492188 Measuring distance travelled by trains SIEMENS AG 10 Jan 1975 [11 Jan 1974] 1200/75 Heading G1N The distance travelled by a train is determined by a pulse counter ZR normally fed with pulses from an oscillator G linked through a delay device VG to a pulse generator tachometer WR coupled to a wheel axle on the train. The frequency of the pulses WE from the tachogenerator WR and the pulses AE from the oscillator G are compared at FR. If the wheel should spin when called upon to accelerate rapidly, the frequency difference is noted at FR and an output Al, operating through OR gate O1, switches the counter ZR from the WE pulses to the AE pulses, whilst the normal link between the oscillator G and the tachogenerator WR is changed to a control voltage E1 from function generator FG which is based on the known deceleration characteristic of the train. A similar changeover occurs when the wheel skids on application of a braking force. When the frequencies of the pulses WE and AE again agree, the counter ZR is switched back to counting WE pulses from the tachogenerator WR.

Title: An improved method of and apparatus for measuring the heat output of a heating plant
IPC: G01K17/04
Filed: 1939-01-13
Abstract: 523,746. Electric signalling systems. LANDIS & GYR AKT.-GES. Jan. 13, 1939, No. 1231. Convention date, Nov. 4, 1938. [Class -40 (i)] [Also in Group XXXV] The heat consumed by heating plant is measured by ascertaining the difference between the quantities of heat given up to the inflow and return pipes by thermostatically controlled auxiliary heating devices. The duration of closure of a circuit by each thermostat is used as a measure of the heat given up by the thermostat, and the two thermostats may control a differential meter, but as described, current representative of the difference between the heat given up by the two devices is derived from the thermostatically controlled circuits and fed to a watt-hour or other meter, this current being also used for the automatic control of the heating plant. Thermostatically controlled auxiliary heaters 1, 2 are applied to the inflow and return pipes 17, 18 and are electrically heated by coils 7, 9, 10 supplied by transformer 6. The coil 10 of the return device is connected in parallel with the single coil 7 of the inflow device and both are controlled by the inflow thermostat so that the duration of current in coil 9 of the return thermostat is a measure of the required difference in heat quantities and is indicated by meter 15. Heating coil 12 of an externally arranged thermostat 3 is in series with the difference coil 9 and controls the regulator 5 of the heating plant which is thus provided with a cut-off thermostat 4.
