Abstract: An optically controlled selector comprises an optical coupler (1) having a first input (2) for an optical input signal, a second input (3) for an optical control signal and an output (4) for a combined signal, and a resonant cavity (5) downstream of the output of the coupler (1) and arranged to receive the combined signal. The resonant cavity (5) contains an optically non-linear material so that changes in the power of the optical control signal result in changes in the resonant frequency of the cavity (5). In use, the power of the optical control signal controls the transmission or suppression of the optical input signal through the optical cavity. Such a selector acts as a simple switch or to select one from a number of optical signals of different wavelength. Preferably the optical material is active and the optical cavity (5) formed by a semiconductor laser amplifier.

Abstract: In its simplest mode of operation, the arrangement to control the catalytic combination of combustible gases in an oxidation reactor allows one of the gases into the reactor at a constant rate and the other to enter until a predetermined pressure (P2) is reached due to its excess. The flow of the second gas is then stopped until combination in the reactor between the two gases causes the pressure to fall to another predetermined level (P1), greater than or equal to the starting pressure (PO). The flow of the second gas is then restarted until pressure P2 is reached again, and so on, so that the pressure in the reactor varies continually between P1 and P2. If the flow of the first gas is decreased or stopped some time after the flow of the second gas is stopped, P1 will be reached more quickly and so be more easily detected by the sensor. During the time the flow of both gases is stopped, the reactor can be opened to the atmosphere, or collecting apparatus; P1 will be reached even more quickly, and accumulations of gaseous impurities (e.g. N2) which may prevent P1 being reached at all, will be ejected. The reaction can also be controlled by measurement of the flows of inputs and outputs.

Abstract: Device for operating a redundant multiprocessor system for the control of an electronic signal mechanism. A coordination processor (ER) assigns to each operation control area processor (BR1, BR2) an operating address ("07", "08"), transmits this by means of a module address ("87", "88") to the processors and provides the processors with the data required for process control. The operation control processors (BR1, BR2) communicate with one another and with the coordination processor using the operating addresses allocated to them. If the coordination processor (ER) detects the failure of an operation control processor (BR1), and if an operational standby processor (BRR) is available, then the coordination processor assigns the operating address ("07") of the failed processor (BR1) to this processor (BRR) by addressing it via its module address ("89"), provides it with the relevant data for process control and includes it as the new operation control processor in the processor network. The remaining operation control processors (BR2) communicate with the previous standby processor (BRR) using the operating address ("07") allocated to the previous operation control processor (BR1) and now to the previous standby processor (BRR) without being informed that anything has changed in the hardware of the processor network as a result of the failure of a processor (BR1) and the activation of a standby processor (BRR). <IMAGE>
