Patent DE-4226134-A1 (DE)
Title: Monitoring and control device for opening and closing of vehicle electric windows and sliding roof - has body-mounted light emitter and receiver with photoconducting strip on window etc. so position can be determined
Inventor: HUELSMANN ULRICH
IPC: E05F15/43
Filed: 1992-08-07
Abstract: The device for monitoring or control of the opening and closing of certain vehicle items (electric windows, sliding doors, sliding roofs, etc.) has at least one electric motor per item, connected to the vehicle electrical power supply. The motor is connected directly to the item through an actuator and indirectly through a light emitter, a light receiver and a flat rectangular photoconducting strip mounted on the item. Light from the emitter is reflected internally along the strip and passes to the receiver. The output signal from the receiver is a function of position and is evaluated to control the opening/closing process. The surface of the photoconducting strip may have a high mirror finish or may be diffused and relatively dark. ADVANTAGE - Increases safety in preventing limb from being trapped in door or window.
Patent DE-4227094-A1 (DE)
Title: Construction support for bridge sections - comprises rail or bearer whose free end has rigid bearing with recess to take inflatable container
Inventor: GHERING JAN
IPC: E01D19/00
Filed: 1992-08-17
Abstract: The rigid bearing end (2) of the rail or bearer (8) has a ground contact area immediately underneath it. The underpart (7) of the inflatable container, when it is inflated, projects beyond the ground contact area, but when compressed it does not do so. A trip valve (10) allows the medium in the inflatable container to escape when the rail or bearer rigid end is directly over its bearing position. The inflatable container (6) transmits the bearing pressure derived from the dead weight of the bearer and bridge on to the ground contact area (4). Thus a proper full bearing is achieved. ADVANTAGE - The bridge can be easily dismantled by reversing the process.

Title: Method for starting up power station (electrical generatoring station, power plant) systems after a total failure of steam generation
Inventor: WOEDTKE WOLFGANG VON PROF DR
IPC: F22B29/02
Filed: 1993-06-25
Abstract: The invention relates to a method for starting up power station systems after a total failure of steam generation, in particular for starting up a steam boiler using the once-through flow (forced flow) principle with superimposed circulation. The object of the invention is to start up power station systems after a total failure using the existing steam boilers without auxiliary steam. This is achieved according to the invention owing to the fact that auxiliary steam generation is realised by means of firing lighting-up oil (light oil), that instead of a filling line known per se between a seal water system belonging to a low-pressure system and a feedwater line belonging to the high-pressure system the steam boiler uses a machine condensate feed line, and that machine condensate is fed directly from the low-pressure system into the high-pressure system or the feedwater tank (storage tank) and the electric feed pump are driven by means of cold water. The turbo-generator set (turbine generator, turbo-alternator) and the machine condensor are not evacuated, so that on the one hand the feedwater is preheated and deaeration occurs in the feedwater tank and on the other hand, there is a simultaneous evacuation of a turbo-generator set. The result is normal feeding of the steam boiler or boilers, and thus normal start up of the steam boiler or boilers is achieved. <IMAGE>

Title: Circuit arrangement for ring tripping (turning off the ringing voltage) in an electronic subscriber circuit
Inventor: MANICKE ULRICH DIPL ING
IPC: H04M19/02
Filed: 1993-08-11
Abstract: Electronic subscriber line interface circuits contain sensitive current identification circuits (S) which monitor the current (I) in the subscriber loop. The ringing of a subscriber is signalled by rhythmic interruption of an AC ringing voltage which produces an alternating current in the subscriber loop. AC ringing voltages are normally de-activated near to the zero transition, but, in the switching phase, there is the risk that, as a result of the capacitive load of the connected subscriber line interface circuit, a current flows which deceptively simulates a loop current and leads to erroneous loop identification. This erroneous response is eliminated according to the invention by means of a comparator (K2) with a very low reference voltage (UV) whereby, following evaluation of the loop current (I) by a current identification circuit (S), the ring tripping is carried out in the immediate vicinity of the zero transition of the loop current and the cause of the erroneous loop identification is eliminated. <IMAGE>

Filed: 1993-10-26
Abstract: The invention relates to the separation of tobacco fibres within the distributor of a cigarette-strand machine. The object is to carry out the separation effectively and in a way which treats the tobacco carefully. This is achieved within a falling shaft (8) of the distributor, into which the tobacco (7) is transferred in a manner accelerated downwards in a main flightpath (41). Provided in the falling shaft (8) limited by mutually opposite channel walls (42, 43) are alternately offset air slits (44, 46), through which blowing air is directed essentially transversely to the flightpath (41) towards the tobacco flying downwards, with the result that the latter is alternately deflected laterally out of its flightpath. The lateral deflection is advantageously associated with a loosening and separation of the tobacco fibres which have an advantageous effect on the quality of the finished cigarettes. <IMAGE>
