Patent DE-4122975-A1 (DE)
Inventor: DENZ HELMUT DIPL ING
IPC: B60K15/035
Filed: 1991-07-11
Abstract: A process for establishing the efficiency of a tank ventilation system of a motor vehicle subjects the signals for the flow volume through the tank ventilation valve (18) and the signals for the pressure difference between the inside of the tank and the environmental pressure to a cross-covariance analysis. Here, said signals are shaped by a high-pass before the cross-covariant function is formed and the maximum or mean of the cross-covariant function concerning the product of the two input values is found. The variant mass is found for the signal of the flow volume through the tank ventilation valve (18) and a transfer factor is calculated from the variant mass and the mean or maximum. If the transfer range lies in a predetermined field, the tank ventilation system is regarded as efficient. One advantage of the process lies in its independence of pressure variations in the tank which are not caused by flow volume changes through the tank ventilation valve. The main changes concerned here are those caused by the sudden development of gas in the tank (10) which, for instance, can be brought about by fuel swash.

Title: Sawn-timber alignment table for woodworking machine - retracts chain dogs from work as supporting beams swing down into aligned position
Inventor: SCHMID LUDWIG
IPC: B27B31/06
Filed: 1992-09-29
Abstract: The beams (1a-c) are at right angles to the machining direction of the work (H), and contain chains (5) with driving dogs protruding upwards moving it along them. The beams swing downwards on an axis (3) parallel to the machining direction from the horizontal position, so as to transfer the work to a lengthwise conveyor. The chain in each beam runs round sprockets (6a) moving with the beam and others (11) in fixed positions. Thus when the chain drive is switched off, its run whose dog is bearing against the work is moved in the reverse direction, thus retracting the dog clear of the work as the beam swings down, the chain being held stationary at a predetermined position. USE/ADVANTAGE - Sawn-timber alignment table for woodworking machine is fast working, with no need to switch chain drive on again to retract dog.

Title: Process for the preparation of substantially uncrosslinked styrene copolymers
Inventor: SCHELLENBERG JUERGEN DR
IPC: C08F212/08
Filed: 1993-06-11
Abstract: The object of the invention is to develop a process for the preparation of substantially uncrosslinked styrene copolymers with acrylates or methacrylates having relatively high weight-average molecular weights in the range of from about 200,000 to 1,000,000 by bulk/solution polymerisation of the monomers with relatively high space-time yields without additional and complex process steps. This is achieved by carrying out the polymerisation with addition of specific amounts of one or more polyfunctional vinyl monomers to a certain conversion range of the monomers and to certain gel contents.   The areas of application of this process are substantially uncrosslinked polymers having relatively high weight-average molecular weights, for example binder components in hot-melt adhesives and coating compositions, components in powder coatings (paints) and electrophotographic toners or components for modifying the properties of plastics.
