Title: Friction-wheel mechanism
Inventor: RUEHLEMANN JOACHIM
IPC: F16H15/38
Filed: 1988-07-29
Abstract: The invention relates to a mechanism in which the intermediate wheels revolve. During this process, they are supported on a fixed disc and they transmit the resulting rotary motion to the output disc, which is rigidly connected to the output shaft. The output shaft can execute a rotary motion in the opposite direction to or same direction as the input shaft depending on the transmission ratio. It is possible to achieve stepup and step-down ratios in ranges from about i = 0.4 to i = infinity and from i = infinity to i = -0.4. This mechanism is suitable, in particular, for use in small electric vehicles. In the vicinity of the point i = infinity, i.e. also n2 = 0, it develops its maximum torque. At point i = infinity, the mechanism is locked and does not permit movement of the vehicle until the wheels enter into frictional engagement. The entire operating range is covered with a constant input speed. It is thus possible, in conjunction with the input side, which is designed as a flywheel mass, for the engine to operate as a generator for energy recovery from braking operations.

Title: Bar-type lock
Inventor: MOJE HANS-WERNER
IPC: E05C9/08
Filed: 1988-09-06
Abstract: A bar-type lock for locking a closure part which closes a chest (box) exhibits a bar which can pivot about its central axis and is provided, at at least one of its ends, with a hook. In the locked state of the chest, the hook grips behind a counter-piece which is connected fixedly to the chest. The longitudinal axis of the counter-piece runs approximately parallel to the central axis of the bar connected to the closure part. The longitudinal axis runs in a plane which extends approximately plane-parallel to a chest wall on which the counter-piece is fastened. The counter-piece is fastened on the wall of the chest by means of a base plate. Provided in the base plate is at least one slot, through which at least one fastening extends in the direction of the wall which bears the counter-piece. A retaining means on which the counter-piece is fastened projects from the base plate.

Title: Mounting for operating instruments for wheel-chairs
Inventor: BAMBERG HERMANN
IPC: A61G5/04
Filed: 1988-09-28
Abstract: The invention relates to a mounting for operating instruments for wheel-chairs which comprises a support arm fitted on the wheel-chair and a receptacle for the operating instrument housing. It is the object of the invention to design the mounting for operating instruments in such a way that it no longer obstructs the user of the wheel-chair on climbing-in or climbing-out and ensures free access during climbing-in and climbing-out. The invention resides in the fact that the receptacle for the operating instrument housing is connected to the support arm via a connecting rod and that a gear which ensures parallel adjustment of the receptacle during pivoting of the connecting rod is provided parallel to the connecting rod.

Inventor: FOCKE HEINZ
IPC: B25J15/06
Filed: 1989-05-03
Abstract: The invention relates to a method and a conveying device for the removal of objects, in particular square objects, e.g. cardboard boxes, arranged in a close-fitting array on a base. Since such objects cannot be slid easily across the base, the method involves tilting the object about a bottom edge opposite to a free (accessible) side of the object, and the device involves means for tilting the object and removing it from the base. In the embodiment, one or more suction grippers (23) are mounted on a piston-and-cylinder device (22) which in turn is mounted for arcuate movement in a slot (31) in a member (16). The member (16) is mounted for arcuate movement on articulated arms (12), to move the objects from the base (25) to a conveyor. A fork (24) is arranged on the member (16) to support the objects when they are pulled off the base.   <IMAGE>

Title: Write protect facility - uses code word generation and comparison to control removal of write protect condition
Inventor: NETH ALOIS DIPL ING
IPC: G06F12/14
Filed: 1990-06-19
Abstract: Data transfer between the micro-processor (uP) and the non-transient memory (NFS) is via a data-address-bus (DAB).  A write sequence is initiated by a microprocessor (uP) generated serial code word (P1) being transferred to one input (A) of an equivalence comparator (AK) via a serial to parallel converter (SPW).  The second input (B) contains the reference code word.  If the microprocessor (Up) and reference code words are equivalent a signal output (P2) is produced which removes the write protect condition from the non-transient memory (NFS). The microprocessor (uP) read clock output (RD) is connected to the serial to parallel converter (SPW) input clock which re-establishes the write protect condition by causing non-equivalence during a read operation. USE/ADVANTAGE - Guards against spurious removal of the write protect condition - Code word comparison also ensures that microprocessor operations are functioning correctly.

Combustion chamber is supplied with coal (7) and limestone (35A) and slag receiver is supplied with ground glass (35B). Flue gas (15) passes through an economiser (17), a DeNOx catalyst bed (19), an air preheater (21), an electrostatic filter (23) and a desulphurisation unit (29) before being discharged through a stack (31).  Ash from the filter is recycled (25) to the combustion zone. Process is esp. useful for disposal of fly ash (contaminated with Pb, As, etc.) from coal-fired power stations.  Pollutants accumulate in the slag, which may be safely disposed of and poisoning of DeNOx catalysts by As2O3 is minimised.
