Patent DE-4138420-A1 (DE)
Inventor: ERNST HANS-HELLMUT
IPC: B60N2/225
Filed: 1991-11-22
Abstract: A hinge fitting for motor vehicle seats with adjustable back-rests has a fixed hinge part (2) associated to the seat (212) and a swivelling hinge part (1) associated to the back-rest (213). Both hinge parts are pivotably interconnected by means of an eccentric wheel (4) and both hinge parts have interlocking teeth (1a, 2a) that form parts of an oscillating mechanism. The eccentric wheel can pivot around a first pivoting axis (20) in a first pivot bearing, with respect to one hinge part (1), and around a second pivoting axis in a second pivot bearing, with respect to the other hinge part (2). Both pivot bearings are eccentrically arranged with respect to each other. The pivot bearings are formed by plain bearing bushes (5, 6) inserted into the hinge parts and/or the eccentric wheel. The plain bearing bushes can be plastically compressed by means of a calibrating mandrel for the purpose of calibration. The running surface of each plain bearing bush keeps the smallest spacing from the corresponding axis of the hinge fitting part that receives the plain bearing bush. The hinge fitting has only a small axial overall width, and a high inner stablility, even against high forces, such as those that can occur during accidents. In addition, the hinge fitting has extremely reduced bearing clearances that can be obtained by simple manufacturing processes.

Title: Feed system for advancing tree trunks in collecting units - uses flexible oblong contact belt to produce friction feed
Inventor: ANDREASSON OLOF INGVAR
IPC: A01G23/08
Filed: 1991-11-30
Abstract: The feed mechanism has advancing tree trunks through processing machines has two advancing belts (22) which act in alternation and which can be moved in a direction parallel to the trunk wherein each belt forms a friction belt which runs on two separate and axially parallel advancing wheels which come into contact with the trunk along an enlarged part of the friction path on the corresponding opposite sides of the trunk. The advance or conveyor belt (22) forms a flexible oblong contact surface which through the effect of the pressure against the trunk automatically conforms with the shape of the trunk and when this contact pressure is lifted returns to the substantially original flat shape. The conveyor belt can be attached at the side edges to an endless drive chain (20). ADVANTAGE - Since the contact pressure of the conveyor belt against the trunk is evenly distributed over a relatively large surface area the specific contact pressure is relatively low avoiding damage to the trunk.

Title: Gas=tight multilayer containment wall for nuclear installations - comprising supporting wall, covering sealing layer and outer protection wall fastened firmly to support wall
Inventor: DANISCH RUEDIGER DIPL ING
IPC: G21C13/10
Filed: 1992-04-03
Abstract: A multi-layer wall forming part of a containment arrangement for nuclear sites, for example tanks or caves. The wall comprises a supporting or building wall (2) covered on at least one outer surface by a sealing layer (4) and a protecting wall (5). The latter is fastened firmly to the supporting  wall (2). The fastening is by means of bolts (6) which are fixed in the supporting wall (2). The sealing layer (4) is glued around the bolts to ensure a gas (and fluid) tight seal is maintained. Other fastening methods can be used. The protecting wall (5) can be made up of a number of parts firmly fastened to each other and the supporting wall. It is temperature, radiation, impact and corrosion resistant. ADVANTAGE - Prior art has comprised twin walls with a sealing layer between them. This has caused problems due to relative movement of the two walls. The claimed wall is cheaper as only one wall foundation is needed. Relative movement of the two walls is smaller. The supporting wall can be made of cheaper material as the protecting wall absorbs the various housing influences.

Inventor: FENNEL HELMUT DIPL ING
IPC: B60T8/86
Filed: 1992-08-14
Abstract: In order to reduce undesired effects of motor drag moments (MSM) on the braking behaviour of a motor vehicle fitted with an anti-lock braking system, the braking slip ( lambda 1,2) of the driven wheels is detected independently of any brake actuation.
