Abstract: An operator-unattended system for the processing of articles selected for purchase includes a subsystem for processing discount coupons bearing codes indicative of the identity of an article and a coupon monetary value. The subsystem comprises a coupon receiver (48) for reading the codes of received coupons and a coupon validator (62) and means for returning the coupon to a customer of the article. A storage device (42) stores signals indicative of the identity of all articles selected for purchase by the customer as derived from the operator-unattended system. A coupon discount totalizer (74) receives those signals from the coupon receiver for which a coupon validation signal is generated and a signal, derived from the operator-unattended system and indicative of price totalization for all the articles selected for purchase and subtracts the monetary value in each of the received signals from the monetary value indicated in the price totalization signal. <IMAGE>

Inventor: KERSTEN KLAUS-DIETER DIPL ING
IPC: H01H71/02
Filed: 1990-04-07
Abstract: 2.1 Fault-current protection switches for different rated currents have been in use for a long time in different designs with considerably different dimensions. Because of a requirement for a switching performance of 10 kA with a back-up fuse of 100 A, it is unavoidable to search in new ways for fault-current protection switches which cover a range of rated currents from 16 to 125 A. 2.2 The invention exhibits a fault-current protection switch which, based on a four-way basic switch for 63 A (module width 4M), covers the complete protection range from a two-way design for 40 A (module width 2M) up to the four-way design for 125 A (module width 5M). An extinguishing device (9), a contact set (10) and a drum controller (11) for each switch pole are inserted, corresponding to the width of a module (1M), in all switches in a lower part (1) of the housing, and a switch locking mechanism (12), including a trip device (14) having a module width (1M), a summing current transformer (13), a test device (15) and a contact position indicating device (16) are arranged in the upper part (3) of the housing. The high content of common components and the assembly sequence which is always the same, that is to say the virtually identical internal construction of the switches for different rated current intensities, leads to a switch family which extends from two-way fault-current protection switches which are 2 modules wide up to four-way fault-current protection switches which are 5 modules wide. 2.3 Such fault-current protection switches are provided for high powers in low-voltage networks. <IMAGE>

Title: Cleaning of air vortex spinning head - in which direction of air flow through spinning head is reversed and waste is removed by suction
Inventor: GOEBBELS HEINZ-DIETER
IPC: D01H11/00
Filed: 1990-08-18
Abstract: An air vortex spinning head for staple fibre is cleaned by reversing the direction of air flow in the spinning jets while preventing the exit of air from the mouth of the air channel.

Patent DE-4035190-A1 (DE)
Inventor: MEYERHOF HARTMUT
IPC: G04G15/00
Filed: 1990-11-06
Abstract: A time switch device (31) for a sequence of control signals (39) to be transmitted as a function of time, for example for the time-dependent variation of command variables in control engineering or for directly switching operating or checking devices on or off as a function of time, is intended to be capable of easier control by an operator while being designed for greater ease of production. For these purposes, the ability for the time-locking circuit to be influenced manually by the user or for it to be decoded by interrogation is completely abandoned, and instead the time switch device (31) is fitted from the outset in the factory with a lithium battery (32), which is typically designed with a lifetime of at least ten years, and taken into operation such that it cannot be switched off. This time switch device (31) therefore already runs correctly when commissioned without the need for the operator to intervene in its functioning. All that remains necessary manually is to select between a number of prescribed switchover time sequences by means of a program changeover switch (37), for which purpose there is also no need for any user guidance on the display, which means that it is also possible to abandon a (time) display, including the functionally critical multiple connections to display/control circuits, which are complicated in terms of circuitry, and likewise to abandon the setting switch wiring that is otherwise required for intervention in the time-dependent switching sequence. <IMAGE>

Patent DE-4121569-A1 (DE)
Inventor: HEIDEMANN ROLF DR
IPC: H04B10/2513
Filed: 1991-06-29
Abstract: To compensate for nonlinear distortions in analog optical communication transmission systems, caused by laser chirps and the chromatic dispersion of the optical fiber, an equalizer in the form of an LC component is known, whose capacitance is formed by a variable capacitance diode. If this equalizer is to be adjusted for considerable signal distortions (long transmission path length), it must operate at great capacitance, which reduces its bandwidth. In order to be able to equalize large bandwidth signals (e.g. 600 MHz) containing considerable distortions, the invention indicates an LC chain circuit with LC components of the known type, as the equalizer. Further developments of this solution concern the appropriate polarizing of the variable capacitance diode and maintaining the frequency response constant, when adjusting the equalization.
