Abstract: A system in a subsriber television network for enabling descrambling of a received scrambled signal on a prepaid basis and/or an impulse-purchase basis. A received mask signal uniquely related to the scrambled signal is compared with a received authorization signal indicating whether the subscriber is authorized to receive the scrambled signal on a prepaid basis and a prepaid signal for enabling descrambling is provided when the compared signals match. A non- prepaid signal is provided when they do not match. A received cost signal indicating the charge for descrambling the srambled signal and a received credit signal indicating the subscriber's accumulated credit are processed with reference to a stored record of the subscriber's prior accumulated charges to determine whether the subscriber has sufficient available credit to pay for descrambling of the scrambled signal. If a program is not prepaid and if sufficient credit is available, the subscriber is given the option of causing the signal to be descrambled on an impulse-purchase basis. To prevent a subscriber from obtaining descrambling through such deceit as changing the mask, authorization, cost and/or credit signals, these signals are processed with key signals which are used in scrambling and descrambling the television signal such that descrambling is prevented if any of the mask et al signals is changed.

Abstract: Upon unauthorized removal of a car radio (2) from the chassis (C) of a car, a memory (5) which has a code stored therein is changed and inhibits operation of the car radio. The memory is retained in a predetermined memory state either by continuously receiving data inputs, for example from a potentiometer slider of a potentiometer (6), or data entered into an RAM energized only upon being properly connected in the vehicle. Alternatively, a user may enter a code, for example by operation of station selector buttons (4) of the car radio (2), and upon operating a set code switch (9), which code is destroyed upon removal of the radio, or upon failure to enter the correct code from time to time. The selected code can be encrypted by a preset encrypting memory chip, for example within the memory (5), and the encrypted code displayed, with only the manufacturer knowing the encrypting data, and releasing the encrypting data only to an authorized person, thereby permitting continued use of the radio by the authorized person even though the code word may have been forgotten.

Abstract: A process is disclosed for exchanging hardness ions and selectively removing nitrate ions from a liquid, e.g. water, comprising passing the liquid through a cation/anion exchange resin mixture, whereby (i) hardness ions are exchanged, (ii) cations and nitrate ions, present in the liquid before its passage through the resin mixture, are each independently removed or reduced to a desired level, and (iii) the anion exchange resin is loaded with nitrate ions to at least 80% of its nitrate removal capacity, and wherein the resin mixture is at least initially regenerated with chloride salt. If the process is used to soften and selectively remove nitrate ions from water, the disadvantageous precipitation of calcium carbonate and/or calcium sulfate during subsequent regeneration of the resin mixture can be avoided. The invention also discloses a resin mixture suitable for use in the process.

Abstract: The device includes a guide column within which a weight falls under gravity to strike e.g. a tool. Shock-absorbing material is located at or near the base of the column such that it enables force to be transmitted from the weight to a tool.

Abstract: A fluid purification system includes an elongated ultraviolet radiation emitting tube and independent fluid flow-controlling conduits. Each conduit is transparent to allow ultraviolet light emitted by the tube to enter the conduit, and defines a continuous, aand is helically wound closely about the tube to insure that fluid flow through the conduits is exposed to the ultraviolet light. The system includes a filter having inlet and outlet ports. An end of each conduit is connected to one of the inlet and outlet ports of the filter. The system thus exposes the fluid to ultraviolet radiation both before and after the fluid is filtered.

Abstract: A clutch amplifier for motor vehicles with a pneumatic- hydraulic or just a pneumatic action has in the pneumatic section a hydraulic clutch wear take-up device in the link to the clutch lever.  The re-setting device consists of a hydraulic column in a cylinder which can be moved by the working piston. This acts as a click-and-ratchet device and transfers the force of the actuating piston to the working lever connected to the clutch lever.  The chamber for the hydraulic medium inside the cylinder can be joined by a resetting valve which acts on the slider principle as a function of the displacement in conjuction with a chamber when the working piston returns.  This is limited by a spring-loaded compensation piston.  The actuating piston carries a seal consisting of an O-ring and another PTFE ring.

Abstract: 2.1 The quiescent current of a push-pull output stage is automatically adjusted by providing a sensing element in each branch of the output stage. The two voltages measured across the sensing elements with respect to reference potential are input to a differential amplifier stage, the output voltage of which is compared with a reference value with the aid of a comparator. The circuit exhibits a frequency-dependence of the automatic quiescent-current regulation due to the cut-off frequency of the output transistors used. 2.2 To avoid this frequency-dependence, a phase-rotating section is connected to one input of the differential amplifier, which worsens the common-mode suppression of the differential amplifier at high frequencies. The result of this measure is that the frequency- dependent error is compensated. 2.3 Push-pull output stages with quiescent-current control. <IMAGE>

Abstract: A method and system are disclosed for locally introducing fluid, such as a gas, at a predetermined location into molten resin downstream from a resin injection aperture to form a hollow part. The gas is utilized at the localized area to distribute the molten resin, to eliminated molded in stress and to prevent formation of sink marks in the part during resin solidification. An overflow reservoir (112) outside of the mold cavity (114) is filled with the resin during resin injection and then the gas is introduced into the reservoir (112) through a fluid aperture (116, 118) and into the part. The reservoir creates a cocoon of solidified material to act as a seal to prevent gas leakage. One hollow body formed by the method and system includes a substantially endless hollow body portion with a fluid opening for communicating the interior of the hollow body portion with the locally introduced fluid. The hollow body provides an internal gas manifold and means for greater structural integrity.
