Inventor: GRUENING HORST DR
IPC: H03K17/04
Filed: 1990-12-08
Abstract: The switching arrangement comprises a latching-type semiconductor component (GTO) of known construction. The circuit for turning off the semiconductor component (GTO) is constructed in such a manner that the gain at turn-off IA/IG,peak is distinctly less than 3, particularly less than or equal to 1. The drive during turn-off is hard, that is to say with a high rate of increase dIG/dt and with a high current. A capacitor (Cp) is connected directly in parallel with the semiconductor component (GTO).

Title: Off-premises cable television channel interdiction method and apparatus.
Inventor: WEST LAMAR E JR
IPC: H04N7/16
Filed: 1989-12-04
Abstract: An off-premises cable television interdiction apparatus provides a microprocessor controller for controlling and switching one or more variable frequency voltage controlled oscillators. The variable frequency oscillators selectively jam only unauthorized premium programming transmitted on particular channels of a broadband signal in the clear from a headend to a subscriber. The microprocessor controller controls the variable frequency oscillators to hop between jamming frequencies and jam particular channels under control from the headend. A frequency calibration routine is executed periodically upon power-up to determine gain parameters for the oscillators. A heterodyned variable frequency oscillator may be provided for the interdiction system which moves the frequency of the variable frequency oscillator out of the television band and mixes the variable frequency oscillator output with a fixed local oscillator output to provide a jamming signal that falls in the television band. Gain control using a heterodyned oscillator may instead be provided for use in the interdiction system which uses one channel of the broadband signal as the jamming signal. Automatic gain control may also instead be provided for controlling the attenuation of a variable attenuator in accordance with a gain function determined by interpolation and previously stored in memory by a calibration routine executed periodically or upon power-up. The calibration routine may run concurrently with a frequency calibration routine for controlling the frequency of the jamming signal.

Abstract: In such known disconnecting arrangements for power circuit breakers which can be pushed into switch gear apparatuses, metallic wear occurs as a result of the contact links being displaced on the connecting tabs of the power circuit breaker when the latter is pushed into the disconnecting arrangement or into the fixed apparatus part. This wear is prevented by sleeve-shaped separating elements (10) which are arranged on a separating plate (12) between the fixed apparatus part (3) and the power circuit breaker (2). The separating elements (10) initially hold the contact ends (11), of the contact links (6), apart from one another on the fixed apparatus part (3), until, while the power circuit breaker (2) is being pushed in, its contact elements (4) have been pushed in as far as the contact position in the region of the contact ends (11) of the contact links (6). Subsequently, the separating plate (12) can then be moved from the OFF position (105) either into a TEST position (106) or into an ON position (107) for the power circuit breaker (2), an interlocking device (100), having a retaining hook (103) and a locking lever (104), ensuring that the power circuit breaker on the one hand is always held securely on the fixed apparatus part (3) of the disconnecting arrangement (1), and that, on the other hand, the separating plate (12) cannot be moved into the TEST or ON positions for the power circuit breaker until the drive devices provided for displacing the separating plate have been released by the interlocking device (100) and its locking lever (104). <IMAGE>

Abstract: In pressure electrolysis plants, water is decomposed into hydrogen and oxygen. During this process, the electrolysis cell block is in a pressure-resistant encapsulation and has an electrically nonconductive fluid kept at the working pressure of the pressure electrolysis flowing round it. The conductive fluids used are feed-water and hydrogen. The pressure of the fluid is controlled by means of the pressure of one or both product gases, for example the pressure in the hydrogen separator. The fluid inside the encapsulation can be heated to establish the starting temperature of the process, while cooling is carried out during stationary operation by indirect heat exchange in the encapsulation.
