摘要： A system comprising replicated sub-systems (x, Y, Z) the outputs (5, 6, 7) of which are consolidated to provide a single output (9) by a majority voter (8) for reliability and availability. The integrity of the system, i. e. confidence in the single consolidated output (9), is provided by an electronic coincidence checking (10) arrangement which involves several levels of checking. A first level of checking is carried out on all sub-system outputs (5, 6, 7) by circuits in each sub-system channel. Thus, each channel assesses the other channels and itself for coincidence. These assessments (X' Y 1 Z 1 ; X 2 Y 2 Z 2 ; X 3 Y 3 Z 3 ) are then consolidated in respect of each sub-system at a second level and the final result (11, 12, 13) employed as an inhibit or power supply disabling control if a fault is declared in one sub-system.

摘要： A current steering circuit for comparing the outputs of two channels of a parallel redundant control system. The voltages and senses of the outputs are mirror-images and are fed into opposite ends (A;B) of four terminal resistor network (Fig 1), of two bias arms (R) and two input arms (R), at the centre junction of which is a light emitting diode (D). One of the bias arms contains oscillating switch means (S) which causes the diode (D) bias voltage to oscillate. When the input voltage at the diode cathode is high the diode will emit light and the voltage at the diode anode will oscillate across a predetermined threshold voltage only when the inputs agree. Two or more circuits can be connected together to compare the outputs of several parallel redundant channel.

摘要： A communication channel for conveying quasi-static signals representing several alternative states one of which is potentially unsafe, e.g. the control signal for a signal lamp in a railway control system. Each channel has a signature code (Figs. 1 and 2) which is continuously repeated in different forms, e.g. non-inverted (Fig. 2(a)), inverted, or alternately inverted and non-inverted (Fig. 2(b)), to represent different states. When a potentially unsafe state is indicated, the repeated signature is periodically corrupted according to a predetermined error pattern. The channel receiver (Fig. 4) is arranged such that its output (32,34) can only be held in the unsafe state providing both the signature and the error pattern in the received signal are correct.

摘要： An electronic or computer-based railway control system Including further safety checks in addition to normal safety interlocking. The present system carries out checks to see that operations, such as print switching and signal setting, are carried out in the correct sequence for a given route having regard to the position and movement of a train as indicated by track circuits. In a computer-based system appropriate checking routines may be written into the computer soft-ware.

摘要： A rotary valve for granular or particulate material comprises a rotor which comprises a shaft (1) mounted for rotation about its longitudinal axis, a plurality of vanes (2) carried by the shaft around said axis and parallel thereto and a pair of discs (3,4) carried by the shaft concentrically therewith at opposite ends of the vanes, which discs close at these ends the spaces between the vanes. There are housing means (8) in which the rotor rotates about said axis and a pair of sealing rings (10, 11) concentric with the discs, each of which rings is interposed between the housing means and a respective one of the discs and provides a surface against which the respective disc runs.

摘要： 57 A flaw detector for checking and continuously proving the integrity of railway tracks rails is given a second role to additionally sense markers attached to the rail webs. These markers, for example welded metal blocks, are arranged to reproduce a code word in the flaw sensor outputs representing the location of the vehicle. The code word is then transmitted, together with another code word representing the vehicle's identity, to a central traffic control office via a radio communication channel. The described arrangement may directly replace conventional track circuit apparatus.

摘要： In the receiver of a railway track circuit signal detector an input stage is connected before an anti-alias filter and a digital sampling stage which supplies time-series data samples to a fast Fournier transform processor. The input stage comprises a tuned amplifier stage which «rings» at the track circuit frequency when stimulated by a track circuit signal in the input. The stage acts as a non-limiting, linear amplifier at other frequencies and as a non-linear, limiting amplifier at the track circuit frequency and provides, when stimulated, a virtually pure sinewave output. Since the range of amplitudes is more compressed as a result, more efficient use can be made of the available digital range and of the transform processor.
