摘要： An LED signal lamp comprises at least two separate LED arrays which have separate power feeds and wherein the LEDs of the arrays are positioned with respect to each other such that when lit they provide a composite light signal output and such that when the LEDs of only one of the two arrays are lit they provide a light signal with a visible distinctive pattern. A distinctive pattern is revealed, either lit or dark. Typically this pattern may be formed as a letter such as "X" or "F" or may be formed as a striped effect, for example.
An LED signal apparatus comprises input signal power supply terminals 7,8 for the apparatus; a series connection of switch means S1 to S4 and a ballast load 6 connected across the supply terminals 7,8; an LED signal lamp1,2 connected to the terminals to be supplied with current therefrom; and switch operating means D1 to D4, in the supply path to the LED lamp, for controlling the state of the switch means S1 to S4 in the series connection, whereby total failure or substantially total failure of the current to the LED signal lamp results in said switch operating means D1 to D4 causing said switch means to open to disconnect the ballast load 6 from power from the supply terminals 7,8.

摘要： © A railway vehicle control system particularly, but not exclusively, suitable for controlling single track working. Transponders (5, 6) are located at fixed positions along the track such as an intersection, points and so on, and a vehicle (1) is provided with sensors (7, 8) for detecting the transponders (5, 6). A central control office (15) supplies information concerning an identifying characteristic of the next transponder (5) expected to be detected, when this happens the event triggers apparatus on the vehicle (1) to communicate with the central office (15) which then supplies information to identify the next transponder (6). The same sequence of events ensues as each successive transponder is passed. The transponders may be staggered alternately to opposite sides of the track for identification purposes. If the expected transponder is not detected, but instead a different transponder is encountered, then a vehicle safety function such as the emergency brakes, may be brought into operation.

摘要： A railway vehicle brake actuator employs an electric motor driving through a step-down gearbox to mechanically move the brake blocks. After the initial rubbing contact point the response of the system is non-linear and the motor feedback control involves compensation for said non-linearity. The motor output shaft is connected to a rotary shaft encoder so that the position of the actuator output member, and thus also the brake force applied, can be determined by pulse counting. The ideal relationship between a brake demand signal and brake force is linear. The actual relationship between actuator position and brake force is non-linear. Correction factors covering the whole operating range are stored in a memory against pulse count numbers and used as a look-up table in the feedback circuit to compensate either the feedback signal or the demand signal for the non-linearity of the response.

摘要： To ensure the safe operation of an electronic circuit (10, 12), for example an amplitude modulated carrier signal generator (12), an output (13) of the circuit is analysed to prove the presence of predetermined signal characteristics, for example the carrier signal, or a modulation frequency. The predetermined signal alternatively may be superimposed on an input to the electronic circuit and proved subsequently to be present in the output. The output (13) of the circuit (12) is passed or inhibited, according to whether or not the signal characteristics are proved present, by means of an output enable gate (14) which is self-latching providing the output continuous to be proved correct. A start-up circuit (22) delays a possible inhibit for a limited period following initial power connection to the circuit in order that the output can become established.
