Patent DE-3021512-A1 (DE)
Title: Circuit for day-night changeover of heating plant - uses intruder alarm system for main control during presence of authorised personnel on premises
Inventor: ARNDT KURT ING GRAD
IPC: G05D23/275
Filed: 1980-06-07
Abstract: The sensing circuit has a number of actuating units (AM) e.g. ultrasonic, infra-red etc., connected to the intruder alarm unit (UEA), the signals from these leading the corresponding indicator board outputs (Tab), where during daytime operation, the main alarm is not set off. These indicator outputs are then fed to several diodes (D1-Dx), where the short pulses are gathered and passed to the set input of a flip-flop (FF). The output of the flip-flop (FF), starts a square wave generator (GE), whose pulse train is fed to a multi-stage counter (Z), the output from which, leads to the position input of a monoflop (MF) via a coding switch (CS). The heating change-over control (HS) day to night operation occurs in the usual way by means of thermostats, but should a person be detected for a period of time, a relay (R) closes, operating the heating system in the daytime mode, i.e. high temperature range. This allows an intruder alarm unit to be used to override the central heating changeover, when areas are in use, other than at normal working times. (66p).

Title: Eccentric punch press unit - uses cam movement vertical component for punching and horizontal component for workpiece advancing
IPC: B26F1/06
Filed: 1980-06-21
Abstract: The eccentric cam (6) is working together with a reciprocating part (13) on which by intermediary of pressure springs (14) parts of the tool carriage (10) are connected. The reciprocating part (13) is provided with a fork (15) with a slot (16) oriented in perpendicular direction to the direction of advance of the workpiece. The reciprocating part also works together with a holding-down mechanism (17) fitted with springs (18) by which the holding-down mechanism is suspended from the reciprocating part (13). The slot (16) with bottom surface (16a) is shallower than the eccentricity of the cam (6), therefore when the cam is in its bottom dead centre the punching action takes place. A further rotation of the cam (6) beyond the bottom dead centre advances the workpiece in horizontal direction, with subsequent pressure release of the holding-down mechanism (17) as the extreme point of the cam (6) leaves the bottom (16a) of the slot (16).

Title: Tuning circuit for car radio with automatic search - stores all transmitters providing required programme and selects that providing strongest signal
Inventor: FOERSCHNER ALFRED
IPC: H03J1/00
Filed: 1980-09-11
Abstract: The circuit allows automatic search for the required transmitter over the full tuning range. Each detected transmitter with a given characteristic modulation is entered in a corresp. location of a store with that which gives the best reception quality according to predetermined criteria being fed from the store to the receiver LF stage. The quality of the signal to which the receiver is tuned is continuously monitored with the receiver switched to a different transmitter held in the store when this provides a better signal. The search procedure may be carried out continuously with the detected transmitters for the required station being stored. The circuit prevents the radio from having to be manually returned when travelling through zones covered by different transmitters, without programme interruption.

Filed: 1981-03-12
Abstract: An inlet valve (valve seat 32, 52) and an outlet valve (42, 62) are assigned to each of two identical filters (1, 2). The common valve housing (7) of the four valves has, on its underside, an outlet connection stub for each inlet valve and an inlet connection stub for each outlet valve. On the filter-housing upperside (11, 21), each filter (1, 2) has an inlet connection stub, which hangs releasably on the outlet connection stub of the associated inlet valve, and an outlet connection stub, which hangs releasably on the inlet connection stub of the associated outlet valve. The valve housing (7) is subdivided by a partition wall (77) into an inlet chamber (78), which is common to all the inlet valves (valve seats 32, 52) and is connected to the inlet connection stub (71) for liquid to be filtered, and an outlet chamber (79), which is common to all the outlet valves (valve seats 42, 62) and is connected to the outlet connection stub (72) for liquid which has been filtered. The valves and each filter are dimensioned for half of the flow for which the filter arrangement is provided and are designed such that the fall in pressure, in the case of a short usage period of only one of the two filters, does not exceed the permissible value. This makes it possible to exchange a filter without interrupting operation. <IMAGE>
