Patent EP-0233748-A2 (EP)
Inventor: RISK WILLIAM P
IPC: G02F1/01
Filed: 1987-02-10
Abstract: An acousto-optic frequency shifter having a long interaction region is used as an optical analyzer. A variable frequency signal generator (340) is used to drive an acoustic transducer (316) to launch an acoustic wave in contact with an optical fiber (300). The acoustic frequency is varied over a known range to generate acoustic waves having known wavelengths. An optical signal having an unknown optical wavelength is introduced into one end (302) of the optical fiber (300) in a first polarization mode. The effect of the acoustic wave on the optical signal is to cause coupling of the optical signal from the first polarization mode to a second orthogonal polarization mode. The amount of the coupling is dependent upon the phase matching between the acoustic wavelength and the optical beat length. The coupling between the polarization modes is maximum when the acoustic wavelength is equal to the optical beat length. The intensity of the optical signal coupled to the second polarization mode can be measured to determine the optical wavelength corresponding to the acoustic wavelength when the maximum intensity occurs.

Abstract: An electrical continuous-flow heater, particularly for connection to a three-phase supply. Such a continuous-flow heater is fitted with a multi-pin functional switching-contact device, which closes the heating circuit at the start of the engagement process, and a safety switching device which interrupts all the pins of the heating circuit. In order to reduce the design complexity for both switching devices, the functional switching-contact device (3) and the safety switching device (12) are combined into a single switching or structural unit, a common double snap-spring contact arrangement being provided for both switching devices. This measure permits a compact, space-saving design of the two switching devices which are used for connecting the heating circuit of a continuous-flow heater to a three-phase supply. <IMAGE>

Abstract: Let into the roadway (F) transversely to the driving direction (A) is a pair of pressure-sensitive detector cables (1, 2) which, when a vehicle passes, transmit signals from which the driving time for the distance (D1) between the detector cables (1, 2) is determined. The signals (I1, I1', I2, I2') triggered by each axle of a vehicle when each detector cable (1, 2) is driven over are processed and used to determine the driving time (T2, T3) of the respective axle. A plurality of time intervals are determined in this way and evaluated for the purpose of speed measurement. The determination of a plurality of time intervals enables measurement to be monitored and thus an increase in the reliability of measurement in conjunction with only a minimum increase in outlay.   <IMAGE>

Abstract: An antilock control device for the brake assembly of a motor vehicle having the function of detecting ON and OFF signals supplied from a brake lamp switch (sw) and representative of the operative and inoperative positions of the brake pedal. When the signal changes from OFF to ON, which means that the brake pedal has been trodden, the antilock control function is disabled so that the pressure generated in the master cylinder will be directly applied to the wheel cylinders. This state continues until the antilock device detects locking tendency of any wheel. In addition to the brake lamp switch signals, signals representative of the ON and OFF positions of the accelerator pedal may be supplied to the antilock control device so that the antilock control function will be disabled when either the accelerator pedal position signal changes from ON to OFF or the brake pedal position signal changes from OFF to ON.

Abstract: The invention relates to a hydraulically operated safety valve which is fitted with two electromagnetically operable servo valves. The safety valve has two coaxial valve bodies, which can be operated in opposite directions to one another. One of the two servo valves is designed as a proportional pressure difference valve and one of the two valve bodies is provided with fine control grooves. In consequence, it is possible, in the case of suitable driving of the proportional pressure difference valve, to release, via the fine control grooves, a corresponding cross-section of the pump connection to the working connection and from the working connection to the tank connection, as a result of which the speed and the pressure rise on a load, e.g. on a cylinder or a motor, which is connected to the working connection can be controlled. …<IMAGE>…
