Title: Motor vehicle, especially passenger car
Inventor: DURM JUERGEN DIPL ING
IPC: B62D35/00
Filed: 1987-10-17
Abstract: A motor vehicle, especially a passenger car, has a rear engine and an air deflection device, arranged in the rear area, which can be moved from a rest position running flush with the adjacent body into an extended operating position, the air deflection device in the operating position running at a distance from the body and a transversely running gap area, lying behind this, viewed in the direction of travel, and laterally outer, longitudinally running gap areas being closed by covering elements. So that, on the one hand, the air deflection device can be extended relatively far and, on the other, the rear covering element in the retracted rest position of the air deflection device - viewed in the longitudinal direction - takes up as little space as possible, the covering element for the rear gap area, at least locally, has concertina-like sections which, in the rest position of the air deflection device, lie folded together one on top of another, whereas in the operating position the concertina-like sections assume an approximately flat position relative to one another.

Patent DE-3800715-A1 (DE)
Title: Temperature-dependent volume control valve
Inventor: SCHLEIERMACHER HERBERT
IPC: F01P7/04
Filed: 1988-01-13
Abstract: Temperature-dependent volume control valve, especially for controlling a hydraulic engine cooling fan in an air-cooled internal combustion engine. The liquid volume control in such controllers is achieved by means of the interplay of forces between the pressure of the evaporating liquid through the bellows 4, on to the push rod 5, on the one side, and the opposed spring force on the other side. With one spring built in, the oil throughput in the actual control range depends on the characteristic of the spring, which results in an unfavourable course in particular for the last control phase. By building in two springs, whose pretension is adjustable individually and independently of each other, and whose spring characteristic can be selected to be matched to the beginning and end parts of the control phase, the functioning of the volume control valve is optimally configured. The volume control valve equipped with two springs is especially suitable for the control of a hydraulic engine cooling fan, where the quantity of oil delivered to the coupling in the control phase can be optionally controlled as a function of the temperature development of the internal combustion engine, corresponding to the given conditions. <IMAGE>

Title: Device for sealing vessels
Inventor: KNABE UWE
IPC: B67B3/02
Filed: 1988-12-23
Abstract: In the case of sealing machines, the sealing element transfer devices are arranged so as to be stationary in relation to the sealing assemblies. A solution of this type can be seen as disadvantageous if special measures for handling the sealing assemblies are taken. According to the invention, a sealing machine is to be further developed in such a way that the sealing assemblies are completely freely accessible at least over part of their horizontal travelling plane and can be connected to or acted upon by additional devices, rinsing containers and the like from below. This object is achieved in that the sealing element transfer device is equipped, independently of the sealing assemblies, with its own displacement device which is arranged on the upper part of the sealing unit in a vertically displaceable fashion and in that the sealing element transfer unit can be moved from a normal transfer position to another treatment position opposite the sealing assemblies. The invention is to be applied in conjunction with sealing machines. <IMAGE>

Patent DE-3900718-A1 (DE)
IPC: F16K11/07
Filed: 1989-01-12
Abstract: A process for controlling the movement of the control piston 22 of a pneumatic control valve 7 for a pressurised air-actuated double diaphragm pump is improved in that the control piston 22 is moved by a control medium, preferably by control air, and is held initially in its particular limit and/or reverse position by a holding device against the pressure of the control air for a predetermined period of time and/or up to a counter-pressure of predetermined pressure level. If the control piston 22 is then released by the holding device, it is moved with a thrust force which is always greater than the maximum friction forces occurring. For this purpose the holding device preferably functions with the aid of elastically 35, magnetically 31, 32 or electromagnetically 33, 34 operating components. The pneumatic control valve 7 suitable for performing the process contains the corresponding connections 16, 17 for the control air and is characterised by the arrangement of a holding device 31, 32; 33, 34; 35, 36, operated separately from the pump diaphragm 3, which device is elastically, magnetically or electromagnetically connected in its operation to the control piston 22 in such a way that it counteracts the pressure of the control air at least for a defined length of time and/or up to a defined pressure.
