Patent DE-3517120-C1 (DE)
Inventor: KRUMSCHEID GUENTER
IPC: F02M37/00
Filed: 1985-05-11
Granted: 1986-11-27
Abstract: The invention relates to a fuel supply device for model aircraft. To produce an excess pressure in the fuel tank in order to force the fuel into the engine, the fuel tank is connected to an excess pressure chamber (4) of an exhaust constructed in the form of a silencer. The casing (1) of the exhaust is subdivided by partitions (5, 6) into a number of chambers lying axially one behind the other. The excess pressure chamber (4) and the chamber (3) disposed therebehind in the direction of flow and directly connected to the exhaust gas outlet (9) are interconnected via a valve arrangement (16-18) which so operates after the fashion of a non-return valve that the valves are throttled in dependence on the inclined position of the exhaust. During climbing throttling is particularly heavy, so that a heavier excess pressure is formed in the chamber and therefore higher delivery pressure acts on the fuel in the tank. In this way the engine is supplied with enough fuel even during climbing.

Filed: 1990-12-29
Granted: 1992-05-07
Abstract: The invention relates to a flexible bearing, in particular for supporting a spring eye (8) of a leaf spring on a vehicle, comprising a rubber-metal part (2) with an inner, cylindrical metal part (3), an outer, cylindrical metal tube (4), which has an axial slot and can be pressed into an outer locating eye, in particular the spring eye (8), under radial prestress during assembly, and with a rubber body (5) which is vulcanised in between two metal parts (3, 4), adhering there firmly. According to the invention, rings (9, 10) are slipped onto the inner metal part (3) at both ends and, with the rubber-metal part (2) pressed in, these rest against the respectively assigned end faces of the rubber body (5). The rings (9, 10) are axially fixed, with the result that the rubber body (5) is supported in the axial direction by the rings (9, 10). This ensures that the bearing can be made relatively soft in the radial direction and is nevertheless relatively stiff in the axial direction due to the support of the rubber body (5) against the rings (9, 10), this having advantages as regards comfort and handling particularly in a support for a spring eye. <IMAGE>

Patent DE-4138254-C1 (DE)
IPC: G08B13/194
Filed: 1991-11-21
Granted: 1993-06-24
Abstract: Such methods and arrangements are used in video surveillance systems which monitor a certain area for changes. It is the object of the invention to specify a video control system providing reliable suppression of false alarms and, at the same time, reliable detection of alarm-relevant changes. This is achieved by the fact that in a currently recorded video image which is divided into a multiplicity of fields and in which a brightness value is integrally determined for each field, the quotient of this brightness value and the brightness value of the corresponding field from a preceding image is formed. When an alarm-relevant change is not present, the quotient is approximately equal in all fields whilst the quotient deviates from the other ones in the case of alarm-relevant changes in the relevant fields. <IMAGE>

Patent DE-4438455-C1 (DE)
Inventor: KRENKEL WALTER DIPL ING
IPC: C04B35/573
Filed: 1994-10-28
Granted: 1996-05-02
Abstract: Proposed is a method of manufacturing a friction element designed for frictional contact with a body and for use, in particular, in brakes or clutches. The method calls for a porous carbon block to be produced which approximately matches the shape of the end of the abrasion unit, liquid silicon to be infiltrated into the pores of the carbon block and the block to be ceramized by initiating a chemical reaction to form silicon carbide. In order to further fashion a friction element of this kind to increase its resistance to thermal stresses and so that it is also easy to manufacture, the porous carbon block is shaped, before the silicon is infiltrated into it, in such a way that cavities and/or recesses are formed in certain internal and/or external zones for cooling and/or reinforcement purposes, the cavities and/or recesses retaining essentially the same shape and size after ceramization.
