Patent DE-2810400-A1 (DE)
Title: Gas discharge lamp operation during AC mains failure - uses transistor control of emergency unit which is periodically blocked, thus reversing polarity
Inventor: KLAAS WILFRIED
IPC: H02J9/06
Filed: 1978-03-10
Abstract: A d.c. emergency generator is in parallel with the a.c. network, and its polarity is varied. The method comprises following consecutive steps. A reversing pulse generator delivers at fixed time intervals pulses which start the polarity reversal by blocking the transistor control in the voltage converter of the emergency unit. After a specified fixed time interval, longer than the dying out period of the lamp current, the generator delivers a further pulse to the polarity reversal device. After a futher time interval the transistor control of the voltage converter is unblocked.
Patent DE-2811413-A1 (DE)
Inventor: HEIM ALFRED W
IPC: G08B13/187
Filed: 1978-03-16
Abstract: The proximity switching device comprises a transmitter operating with light and receiver which can operate distance-selectively. The transmitter (2) radiating light and the receiver (2) responding to light are mounted pivotably in a chassis (1). Transmitter and receiver (2) are each mounted in a housing (23) so as to be displaceable relative to a lens (26) arranged therein. The direction of the optical axes and the distance of transmitter and receiver (2) from the respective lens (26) can be changed in coordination with one another, force-controlled by means of a pivoting device (3, 4). This device can be used for distance-selective sorting, fine positioning and accurate controlling. It can thus be used for positioning and stock keeping as light barrier or as intrusion protection since it can be adjusted to a desired sensing distance in a simple manner and is insensitive to stray light. <IMAGE>

Title: Separating device for a cutting out machine - using raised pins to lift the pattern out of the material
Inventor: STUMPF GUENTER O
IPC: B26D7/08
Filed: 1978-05-03
Abstract: A device which works in conjunction with a cutting-out machine to separate cut patterns from the waste material by means of individually movable pins which can be selectively operated in a configuration conforming to the shape of the patterns to be separated, and which raise the patterns above the level of the waste cuttings. The pins are disposed in a regular array on the surface of a rotating drum or a moving belt which moves synchronously with the moving sheet of material. Meshing with the rows of needles are the fingers of a comb-like carrier on which the patterns are deposited whilst the waste passes away beneath. Patterns are sepd. quickly and easily from even small amts. of waste without the need for manual intervention.

Title: Automatic freewheel clutch for car - has idling setting of accelerator pedal defined by parallel springs of different lengths
Inventor: HEIDEMEYER PAULUS DIPL ING
IPC: G05G1/46
Filed: 1978-05-27
Abstract: The car transmission is fitted with a servo link to the clutch, to disengage the clutch when the vehicle overruns the idling setting of the accelerator, e.g. when running downhill. This enables the driver to achieve improved fuel saving. The idling position of the pedal is determined by two different length springs (30, 31) in parallel as return springs. One spring provides a constant force on the pedal and the second spring is only operated when the throttle is set higher than idling. This provides the driver with a readily felt idling position so that he can control the freewheel.

Title: Transfer step conveyor system - has high throughput rate with simultaneous workpiece treatment and transfer speed variation during each step
IPC: B23Q7/14
Filed: 1978-11-08
Abstract: The process is intended for increasing the throughput of a transfer conveyor. The conveyor moves in steps and carries identical workpieces particularly in ceramics, to successive work stations for operations of pre-determined equal duration. The step cycles are of constant duration, whilst the velocity of transport during each cycle varies in a pre-determined repetitive sequence. Each work station simultaneously operates on a pre-determined number of pieces, the cycle time being correspondingly reduced whilst the pieces, which are at a station for operations, are kept out of contact with the conveyor.
