Patent DE-3910624-A1 (DE)
Title: Power-failure activated coupled switch
Inventor: MURSCH GUNTER DIPL ING
IPC: H05B37/04
Filed: 1989-04-01
Abstract: A switching element which automatically compensates for the function of the failed load in the event of failure of a lighting means due to cable breakage, fuse tripping or mains failure. The emergency lighting should, however, be capable of being deliberately switched off to allow a relatively large number of emergency lights to be installed with low battery capacity and to allow the user the choice of lights which is otherwise usual. Each load supplied by emergency power is intended to be checkable immediately and without equipment. The main and emergency circuits are switched using a coupled switch. In addition, a closing element which is dependent on failure of the main current is fitted in the emergency circuit. The emergency current thereby only becomes activated when there is a current failure in the main circuit. In order at any time to check that the emergency circuit is operational, a disconnection plug is built into the mains circuit. For lighting systems which require a very high degree of functional reliability, such as, for example, in the operating theatre of a hospital. The simultaneous simplicity of the circuit allows economical construction of relatively large lighting systems which are secured against failure of the main current both in the commercial and in the private sector.

Abstract: A process and apparatus for eradicating pests in organic bulk goods, for example cereals, are provided. According to the process, the bulk goods, from which pests are to be eradicated, are introduced into a pressure-resistant vessel (10) in which compressed air is then first introduced until a minimum pressure of 4 - 6 bar has been reached. Carbon dioxide under a substantially higher pressure is then introduced until a pressure of 15 - 25 bar has been reached in the vessel interior. The pressure reached is maintained over an eradication time of a few hours, whereupon the vessel (10) is then depressurised and the bulk goods from which pests have been eradicated are discharged. As the apparatus, an upright elongate cylindrical vessel (10) with an inflow-distribution pipe (14) extending in its interior is provided, which pipe can be connected via piping (40, 42, 45, 47) fitted with valves (41, 42a, 46, 48) to a compressed-air source (32) and to a carbon dioxide gas source (30, 31). <IMAGE>

Title: Electromotor drive for lock cylinder - operates in conjunction with knob shaft so that cylindrical core can be rotated by gear drive
Inventor: DESCHE PETER
IPC: E05B47/00
Filed: 1989-10-27
Abstract: The coupling(1,2) is designed as a clutch. The feed motion of the coupling is activated by an electrically operated stroking armature so that its linear movement is converted to rotary movement which leads to the axial engaging of the clutch parts.  The armature has an axial extension which, with an offset end, engages in the forward endface of the rotatable first disc(6).  The rotation of this disc results due to the stroke movement of the armature. The disc has coaxial bores accepting several balls(7). A fixed second disc(9) lies against the rear endface of the first disc(6) which has recesses(10) for the balls designed so that the balls move out axially over the forward endface of the first disc. The balls are pushed axially against a spring(11) reacting on the coupling disc(1) arranged on the same axis as the first and second discs(6,9) which is brought in to engagement with the other coupling part(2) across coaxial followers(13). ADVANTAGE - Operation is possible at comparatively low energy cost. Space needed for coupling is small.
