Patent DE-3129523-A1 (DE)
Title: Multi-stage square-wave pulse amplifier circuit
Inventor: HUEBNER-KOSNEY REINMAR DIPL IN
IPC: H03K5/02
Filed: 1981-07-27
Abstract: Each stage of the amplifier circuit in which a number of transistors are connected in series with one another in familier manner with the same polarity with their emitter-collector paths and are connected in series with the load resistor to the DC feed voltage source and the first transistor is connected with its control circuit to the control pulse source, as an auxiliary voltage source a capacitor which, when the stage transistor is enabled, supplies the control current for enabling the subsequent stage and, when the stage transistor is disabled, supplies the bias voltage required for a fast charge carrier removal. The capacitors are charged up to the prescribed part-voltages during the inter-pulse intervals by a voltage divider which includes the emitter resistor and at least parts of the collector resistors of the stages. The auxiliary current needed by the circuit according to the invention is much lower than the current through a voltage divider permanently connected to the DC feed voltage source and used in a known circuit and across which the control voltages required for the uniform distribution of the output voltage to the invidual stages are picked up so that, by comparison, a better efficiency is obtained. The acceleration of the charge carrier removal after the end of the control pulse increases the edge slope of the output pulses and thus improves the transmission quality of the amplifier circuit. The circuit according to the invention is used, for example, in grid-pulsed power tubes in power transmitters.

Title: Protection circuit in the bias voltage supply of a carrier frequency generator
Inventor: LANG HERMANN DIPL ING
IPC: H04J1/06
Filed: 1981-09-25
Abstract: The protection circuit contains a decoupling diode (4) between its input (E) and its output (A). A filter capacitor (2) is connected between the output (A) and an earthed connection of an operating voltage source. A first resistor (3) is connected between the output (A) and the other connection of the operating voltage source. According to the invention, a transistor (4) is provided whose emitter is connected to the output (A), whose collector is connected to the second operating voltage connection and whose base is connected via a second resistor (5) to the input (E). The protection circuit can be used in carrier frequency systems in which rapid charging of the filter capacitor is required when the operating voltage is switched on or when a standby carrier supply is connected in parallel to form an operating carrier supply, in order to shorten the time period of bias voltage deviations at the modulators. <IMAGE>

Title: Heel hold-down
Inventor: KONWITZA VLADIMIR DIPL ING
IPC: A63C9/084
Filed: 1982-04-27
Abstract: The invention relates to a heel hold-down of a ski binding, consisting of a base plate, a bearing body, which is pivotable on the latter about a vertical journal, and a binding housing which is mounted rotatably on said bearing body on a horizontal, transversely running axle, is under the influence of an erecting spring and bears on its front side a holding-down part and a tread arm, the bearing body and the binding housing being engaged in the skiing position by means of a catch spring, and a control mechanism being provided which, in the case of a skier twisting and falling, reduces the release force required to release the engagement of the binding housing as a function of the amount of lateral deflection of the bearing body relative to the base plate. The underlying object of the invention is to remove this disadvantage and to provide a heel hold-down of the type mentioned at the beginning, in which the control mechanism can be accommodated completely inside the binding housing and is of simple construction. This object is achieved in that the axle of the binding housing is formed by a type of crankshaft which is mounted with its crank webs constructed in the form of circular discs in the binding housing and in the bearing body and whose crank serves for supporting the catch spring and is arranged with horizontal spacing from the axis of the vertical journal, a coupler being provided as control mechanism, by means of which the movement of the bearing body relative to the base plate can be converted into a rotation of the crankshaft. <IMAGE>
