Title: Apparatus for monitoring arrival of sheets to machine input station - + has optical position sensor indexed to machine speed by magnetic signal transmitter for feed conveyor and stacking table control.
IPC: B65H43/08
Filed: 1991-12-05
Abstract: An apparatus for monitoring the arrival of individual sheets (10') of flexible material (10) to the input station of a sheet processing machine employs an optical position sensor (20, 21) incorporated at the end of a feed conveyor (13, 14) which is activated during successive time intervals determined by a magnetically operated machine speed transmitter (25, 26). The sheets (10') are initially transferred to the conveyor (13, 14) by the suction-pad (12) from a stacking table (11) which indexes upwards to maintain constant height of the top sheet. Electronic data storage enables a continuing trend of early or late sheet arrival to be corrected. USE/ADVANTAGE - Incorporates all prerequistes for total sheet feed control with a minimum of expense. Has inbuilt capability for early/late trend recognition and correction.

Title: Control of voltage drop in vehicle electrical supply - requires two separate batteries charged up in parallel, one for starter motor, one for remainder of circuit
Inventor: LANGNICKEL WOLFGANG DIPL PHYS
IPC: B60R16/033
Filed: 1993-02-02
Abstract: In order to control the main voltage supply in cars which have at least one heavy load (like a starter motor) and weaker loads (e.g. the lighting circuit), two batteries in parallel are provided, charged up from a single generator. The main battery supplies primarily the heavy load and the auxiliary battery supplies the weaker load so that the voltage drop in the weaker circuit is limited when the heavy load is supplied. During normal running, both batteries are charged and when the engine is stationary, the auxiliary battery is disconnected. During the starting process, the starter is connected to the main battery whilst the rest of the car's electrics are connected to the auxiliary battery. ADVANTAGE - Prevents voltage drop in lighting and other circuits when starter is operated.

IPC: B65D85/32
Filed: 1993-06-23
Abstract: It is increasingly the case that food products are subjected to pretreatment frequently no longer taking place at the location at which the actual product is consumed. This is also the case with eggs which are for example painted with colours by special companies for easter time or delivered, hard boiled and peeled, to food companies such as delicatessens or gastronomic companies. The manufacturing method according to the invention is characterised in that a further connection seam (5) is arranged transversely to the direction (arrow) in which the film is fed for the packaging unit (7), which further connection seam (5) separates a previously known chamber into two subchambers which are separated from one another in an airtight fashion and, using a perforation device (12) which is arranged transversely with respect to the feeding direction, a perforation (6) running transversely with respect to the feeding direction or predetermined tear line is let into the connection seam (5) The packaging unit formed by the manufacturing method has for example ten chambers with three eggs each, it being possible to separate each chamber from the other while maintaining the air fuel. <IMAGE>

The feeder electrodes (21a, 21b, 21c, 21d, 21e, ...) have limited length so that the feeder path is divided up into short feeder sections. While the vehicle (1) is moving, the pair of current collector electrodes (11a, 11b) come into contact with successively occurring pairs of feeder electrodes (21a, 21b, 21c, 21d, 21e, ...), in this arrangement the feeder control system (23) controls the feeder switching devices in such a way that precisely the pair of feeder electrodes (21b, 21c) which are in contact with the pair of current collector electrodes (11a, 11b) are connected to the voltage of the feeder device (2), and the other feeder electrodes (21a, 21d, 21e, ...) have zero potential. As the vehicle (1) moves forward, a "switching wave" is produced by means of the feeder switching devices (22a, 22b, 22c, 22d, 22e, ...), and a "potential wave" which supplies the vehicle (1) with electrical energy is produced by means of the feeder electrodes (21a, 21b, 21c, 21d, 21e, ...). <IMAGE>
