Patent DE-3818621-A1 (DE)
Title: Window/headlamp washing device for motor vehicles
Inventor: LEHRHUBER BARTHOLOMAEUS
IPC: B60S1/48
Filed: 1988-06-01
Abstract: Known window/headlamp washing devices for motor vehicles with liquid-cooled engine have a washing fluid container from which a line leads to spraying elements on a window or headlamp. This line can be heated, by means of a heat exchanger, by the cooling fluid heated by the engine. It is disadvantageous here that only a portion of the washing fluid is heated up whilst the portion located behind in the direction of flow remains frozen at low external temperatures. So that heated washing fluid is always available even just after the engine has started and also at low external temperatures, according to the invention a heat exchanger is constructed in the washing fluid container (26). For this purpose, a feed line channel (30) branches off from the first section (14) of the cooling fluid line of the engine (10), which feed line channel (30) leads as a heat-outputting line (32) in a helical shape through the washing fluid container (26). Additionally, a bypass line (36) which has heat exchanger elements in the region of the spray elements (20), which heat the said spray elements (20), can branch off from the feed line channel (30). <IMAGE>

Patent DE-3828889-A1 (DE)
Inventor: BECK WOLFGANG DIPL ING
IPC: B60L5/28
Filed: 1988-08-25
Abstract: The current collector for electrically-propelled vehicles with overhead line supply is equipped with an automatically acting device for fast lowering which is triggered as soon as parts of the pantograph are deflected by an inadmissibly large force acting parallel to the travel wire. As a result, control signals are generated which bring about, by means of activation units, the fast lowering by uncoupling the lifting drive or sudden pressure reduction in pneumatic or hydraulic lifting drives. The device for fast lowering is automatically reset. <IMAGE>

Title: Device for driving a variable delivery (displacement, volume) pump
Inventor: KIPP JOHANN-CARSTEN DR ING
IPC: F04B1/32
Filed: 1988-12-01
Abstract: A description is given of a device for driving a variable delivery pump with the aid of a hydraulically driven directional control valve via which at least one of the working chambers of the variable delivery pump can be pressurised or relieved as a function of the control pressure. In order to permit the variable delivery pump to be operated in the closed electrical control circuit by means of a very simple technical outlay, provision is made as directional control valve of a multiport (multiway) proportional valve whose valve piston is exposed to the force of a spring which biases the directional control valve into a position which increases the pump pressure to the output pressure of an electrically adjustable pressure control valve.

Title: Electrically operated scarecrow with rotating metal bands
Inventor: WILHELMS WALTER
IPC: A01M29/16
Filed: 1989-02-08
Abstract: As a result of the wilder constant rattling of the bands, the additional bird alarm cries and the noise of other birds fluttering away therefrom, the scaring effect is increased decisively. The improvement of the band suspension protects the bands from tangling and thus prevents the jamming of the motor, avoids the reduction of the band rattling as a result of wet and rain and makes night-time switch-off or twilight switching more light-sensitive. The additional and the modified components bring about reverse battery protection, louder and current-saving sound and protect the circuits against problems, e.g. as a result of switch-on and switch-off voltage spikes of the motor and the resonance frequency of the pulse signal transmitter, have a more effective interval operation as a result and ensure a wilder constant rattling and elimination of the many, costly large capacitors. Night-time switch-off is brought about by an additional photoresistor in the existing circuit.

Title: Catheter system for cardiological diagnosis
Inventor: NIEDERLAG WOLFGANG DR RER NAT
IPC: A61B5/0215
Filed: 1989-05-26
Abstract: The invention relates to a catheter system which permits high-resolution, artefact-free, intracardiac pressure measurement, permits quicker cold injection during thermodilution and enables the diameter of the catheter to be reduced. According to the invention, a miniature pressure transducer based on a piezoresistive resistance structure integrated in silicon is located on the tip of the catheter. The pressure transducer forms a structural unit with a thermosensitive electrical element. The catheter comprises a thin tubular material capable of flotation, via which connection wires and gaseous media can simultaneously be fed. Moreover, there are a sleeve-shaped catheter and a sealable Y connector attached to the proximal end of the catheter, which serve to inject the cold bolus. The invention concerns a catheter system for cardiological diagnosis, especially for recording the intracardiac pressure, the cardiac output and the pulmonary occlusion pressure.
