Abstract: The invention is based on the object of specifying a simple and universal circuit which manages without division of the resonant-circuit capacitance or tapping of the resonant-circuit inductance even at low frequencies. The object is achieved by the fact that a resonant circuit consisting of an adjustable capacitor (C1) and an inductance (L1) is connected via a capacitor (C2) and a diode clamping circuit consisting of at least one Schottky diode (D1) and at least one resistor (R1) to the input (gate) of a junction field effect transistor (JFET) operating in common-drain circuit and having a high transconductance, that a positive operating voltage is connected in parallel with an RF blocking capacitor (C5) at the drain electrode of the JFET and that the output of the JFET is connected via a resistor (R2) to a choke (L2) and a capacitor (C3), connected in parallel therewith, and a resistor (RL). A preferred field of application is for use in portable devices of communications technology. The drawing shows the circuit diagram of the oscillator. <IMAGE>

Abstract: A protection circuit arrangement is proposed for electronic circuits which produce an output signal which is supplied to a sensing resistor, which arrangement has a thyristor whose load path is connected in parallel with the two-wire sensor. A voltage/current converter is provided which monitors the voltage applied to the two-wire sensor and, above a specific threshold value, supplies current to the control input of the thyristor. The sensing resistor, which exists externally, of the current loop circuit of the two-wire sensor is used for current limiting and power-loss conversion in the case of overvoltages. <IMAGE>

Abstract: A backrest (10) which can be fitted on a lifting plate of a lift assembly has a foot (12) and a plate (14) which can be pivoted on the latter about a pivoting axis (34) and forms the backrest. On the back, a transversely extending support wall (44) is attached or moulded onto the plate (14) with sufficient distance from the pivoting axis (34). Arranged between the support wall (44) and the bottom (24) of the foot (12) is a piece of tube (16) which lies transversely, is arranged parallel to the pivoting axis (34), is closed at the end, and is connected via a hand control valve to the compressed-water system of the lift assembly. By filling the piece of tube (16), the plate (14) is raised via the support wall (44) into a steep position, even if the upper body of a user is loading the plate (14). By letting off compressed water in a controlled manner, the plate (14) moves infinitely variably into different positions of inclination right into a flat inclined position in which a rear attachment of the plate (14) strikes against the foot (12). <IMAGE>

Abstract: A power amplifier suitable for use in TDD and TDMA systems in which burst transmissions have to conform to a time mask, comprises a power amplifier (10) having a signal input (11), a signal output (14) and a control voltage input (24). A r.f.feedback control loop is coupled between the signal output (14) and the control voltage input (24). The control loop includes detection means (18) coupled to a comparison means (22) in which the detected signal is compared with reference pulses produced by a generating means (28). The output of the comparison means is coupled to the control voltage input (24). In order to provide a control signal when the output power level is too low to be detected, an artificial detector (38) is connected between the output of the comparison means (22) and its input for the detected signal in order to feed back the control voltage. As a result the control voltage versus power output characteristic is extended which leads to the generation of less transient sidebands and interference.

Date Aug. 6, 1992.To vacuum up a fluid using a vacuum cleaner, there is provided an attachment (1) to which a vacuum cleaner hose (31) is connected. The attachment comprises a separation chamber (3) in which the vacuumed up liquid is separated from the suction air through deposition on the wall surfaces (5, 6, 8, 11) of the separation chamber, with the liquid then dripping down into the collection chamber (21). The liquid is thus completely separated from the air using a common vacuum cleaner without the potential for vacuum cleaner damage. To insure that the suction through the attachment is cut off in the event that the liquid in the container reaches the vicinity of the suction channel, a valve element (18) and a float element (20) are provided which cut off the suction air and therewith the flow of liquid to the attachment when the maximum liquid level has been reached in the container. A finger operated valve can optionally cut off the suction through the attachment to regulate the vacuum.

In a preferred embodiment the sensor system comprises a flared optical fiber pipe and a processing optical system, whereby the narrow cross-sectional end of the fiber pipe can be used to detect the radiation from the test object at a large solid angle. Due to the change in cross section this radiation emerges from the fiber pipe at a much smaller angle that is coordinated with the aperture angle of the succeeding optical system.
