Patent DE-3414008-A1 (DE)
Inventor: SCHMITT WILHELM DIPL ING DR
IPC: F16J15/3256
Filed: 1984-04-13
Abstract: A cartridge seal has concentric outer and inner rings which snap together relatively rotatably to form the cartridge. Each ring has a generally L-shaped, inner axial profile with generally axial and radial legs thereof oppositely disposed. A sealing lip on the radial leg of the outer ring sealingly bears against an abutment surface on the radial leg of the inner ring to accommodate radial excursions during relative rotation therebetween. At least the radial leg of the inner ring is made of a material, for example metal, which conducts heat well. Frictional heat of the sealing lip against the abutment upon relative rotation is thus conducted to the surface of the radial leg of the inner ring opposite the abutment surface for dissipation. Heat dissipation is further improved with depressions in the opposite surface for expanding its surface area and, if the depressions are radial grooves, circulating a fluid medium wetting the surface to carry away the dissipated heat.
Patent DE-3416062-A1 (DE)
Title: Method and device for controlling and shutting off the flow of a medium flowing through a pipe conduit
Inventor: AUCHTER BRUNO DIPL ING
IPC: F16K3/18
Filed: 1984-04-30
Abstract: When controlling and shutting off the flow of a medium flowing through a pipe conduit, it is not possible to prevent severe wear from occurring due to the high friction between the sealing edge of the shut-off member and the sealing ring in the pipe conduit, leading to leaks and requiring premature replacement of the seals. The known shut-off members are furthermore of relatively complex construction. According to the invention, however, these disadvantages are avoided by the fact that in the shut-off procedure the adjusting member (1) is moved into the closed position by displacement and is then displaced into the sealing position with the aid of a pressure medium. <IMAGE>

Title: Arrangement for measuring height, preferably for geometrical levelling
Inventor: FEIST WIELAND DR
IPC: G01C5/00
Filed: 1984-07-30
Abstract: The object of the invention consists in designing an arrangement for measuring height in such a manner that, by increasing the signal/noise ratio between pole division and environment, the accuracy of the photo-electrical measurement data acquisition over long distances increases so that an objectivisation and automation of the measuring process in geometric levelling is possible. The object is achieved by the fact that an optical system with a light source for sending out an infrared or a visible beam of light is arranged in the optical axis of a sighting telescope and that a reflecting division is provided for the measuring pole. It is advantageous if the optical system for sending out the light beam and the sighting telescope have a common optical axis. The invention makes it possible to objectivise the measuring process of the detection of photo-electrical measurement data and to automate the data flow and to increase the accuracy of the visual observation by relieving the observer. This also reduces the number of reading and transmission errors. <IMAGE>

Title: Multi-chamber rear light
Inventor: REISTER GUENTER
IPC: B60Q1/26
Filed: 1984-08-29
Abstract: A multi-chamber rear light, in particular for utility vehicles, is described, having a plurality of light chambers which are arranged one next to the other and are covered by a common lens and are closed off from the outside by a housing in which a light exit opening is provided for a registration number light. The light chambers are formed by a reflector assembly, a drawer-like receptacle guide for a supplementary lamp carrier for the registration number light being provided between two reflectors on the side facing away from the lens and in the region of the light exit opening. This design has the advantage that the lighting effect of the individual light chambers is not influenced if a supplementary lamp for the registration number light is provided because the said light is seated on the rear of the reflectors. In addition, it is advantageous that this registration number light can be used as desired, specifically on both sides so that the new multi-chamber rear light can also be used on both sides of a utility vehicle.
