Patent DE-3801282-A1 (DE)
Title: Shaft covering with safety self-locking mechanism
Inventor: EICHELMANN HORST DIPL ING
IPC: E02D29/14
Filed: 1988-01-19
Abstract: For safety reasons, demands are increasingly made for shaft coverings with a locking mechanism or closure, in particular in pedestrian areas. Coverings with closures require appropriate wrenches (keys) for operation, which has certain disadvantages. The shaft covering corresponding to the innovation has an automatic left/right or left/left or right/right self-locking mechanism. A special wrench for releasing the locking mechanism is not necessary; only a lifting tool. Since the locking mechanism cannot be seen from above, the opening mechanism is also not recognisable from outside. Opening by unauthorised people is thus prevented.

Patent DE-3832961-A1 (DE)
Title: Solar collector and method of covering it
Inventor: STIEFEL GOTTFRIED ALFRED
IPC: F24S23/70
Filed: 1988-09-28
Abstract: For the covering of solar collectors, which have metallised plastic film as the reflector, certain films are particularly well suited, but until now have not allowed themselves to be adhesively bonded on directly. Accordingly, until now the cut-to-size piece of film concerned could only be held on the collector frame by special retaining means. The novel method is intended to overcome this disadvantage. In the case of the novel solar collector, the cut-to-size piece of film is adhesively bonded onto the side walls of the collector frame. This can be achieved by the method in which   (a) the surfaces to be adhesively bonded to each other in pairs are made to begin melting by the effect of heat, (b) an adhesive is applied to at least one of the surfaces prepared in this way, and   (c) the two plastic surfaces are pressed one onto the other.   After stretching and adjusting on the collector frame concerned, the cut-to-size piece of film of the novel solar collector can be adhesively bonded onto the side walls of the collector frame without chemical pretreatment.

Patent DE-3901776-A1 (DE)
Inventor: PANNBACKER HELMUT DIPL ING
IPC: B60T8/88
Filed: 1989-01-21
Abstract: A safety circuit (12) for the surveillance of the proper functioning of an electronic wheel lockup-protected motor vehicle brake system includes automatic control circuits (10, 38), automatically controlled magnet valves (4, 46), and pick-up transducers (3, 47) at the motor vehicle wheels (2, 48) to be monitored. An error message and/or a partial shut-off of a defective pair of circuits, relating to wheel lockup protection circuits relating to diagonally disposed wheels, occurs in this safety circuit when an upward jump or a downward jump is recognized in the measured velocity of the one wheel and, simultaneously, the speed of the diagonally, oppositely disposed wheel or of any other wheel is measured to be above a limiting value. It is thereby avoided that an undesired error message occurs already when a jump in velocity is recognized, for instance in case of a standing vehicle, in case of a starting of the motor, or in case of a beginning of rolling of the vehicle.

Patent DE-3907138-A1 (DE)
Title: Bite indicator for fishing appliances
Inventor: TEIHS RUDI
IPC: A01K97/12
Filed: 1989-03-06
Abstract: Due to their construction type, the hitherto available bite indicators do not always necessarily correspond to the necessary degree of sensitivity when a fish bites. By the clamping-in of the fishing line, a perceptible resistance is present in the case of a number of appliances. Moreover, in the case of most appliances, after the alarm has been given, the fishing line has to be drawn back into the appliance again each time. Consequently, these appliances are difficult to handle. Appliances which retain the line during biting are very expensive. The present bite indicator can be set for any desired degree of sensitivity. It does not oppose any resistance to the fish during biting. In addition, after the alarm has been given, the fishing line is still in the appliance, this facilitating handling. The simple construction type means that the price for this appliance is very low.
