Patent DE-4000081-A1 (DE)
Inventor: UTTSCHEID GEORG
IPC: B61L11/02
Filed: 1990-01-03
Abstract: A switch control for a self-propelled floor transportation vehicle is known, which has a guide shoe which engages in a guide rail. The guide shoe can be laterally displaced with respect to the travel direction so that a desired travel direction can be selected at a fork. The known switch control operates with electromagnets which are arranged on the floor area and act on the guide shoe. If the electromagnet is activated, this leads to the guide shoe swivelling. However, the use of electromagnets in the floor area requires a high degree of expenditure. Therefore, it is proposed to provide fork signalling elements in the floor area, which elements are evaluated via sensor elements in the floor transportation vehicle and actuate drive units for the guide shoe.

IPC: C02F1/52
Filed: 1991-04-27
Abstract: A new device for cleaning the waste water from printing operations consists of two containers (10, 13) linked by a transfer pump (9).

Title: Viscous material strip-parting method - by subjecting strip briefly to load exceeding its mechanical strength causing crack propagation
Inventor: GOLDHAHN HORST DR
IPC: B26D1/08
Filed: 1991-04-27
Abstract: Lengths are parted off from a strip of highly viscous material by exerting a force at right angles to it. At the parting point, the material is briefly and rapidly subjected to a load exceeding its mechanical strength. This causes independent crack propogation and complete parting. The time from load application to when cracking starts can be less than the relaxation time of the material, load being typically applied as a blow. The load can be such that no additional fractures take place, and a notch can be formed to initiate the parting operation. ADVANTAGE - Accuracy without edge distortion. Used for caramel in the confectionery industry, or molten silicate glass or high polymer.

Title: Achieving defined trimming with grinder - using learning process with defined feed rate to determine characteristic grinding curve and subsequent correction process
Inventor: HERRBACH SIEGFRIED DR ING
IPC: B24B53/00
Filed: 1991-04-30
Abstract: The method of achieving defined grinding involves a first learning process with a defined feed rate and in which the characteristic grinding curve is determined from the variations of the radial or tangential force along the grinding curve and transferred to the machine controller. A subsequent correction process involves taking account of the effect on the grinding curve of the structure of the disc surface and of the grinding program. The results are used to influence the feed rate during subsequent processing to compensate for structural changes. ADVANTAGE - Reduces negative effects of structural differences of grinding disc on achieved surface quality.
Patent DE-4117869-A1 (DE)
Inventor: WOEHR PETER
IPC: H04Q11/06
Filed: 1991-05-31
Abstract: The starting point are known space/time switching networks. The technical problem is that the capacity of a switching network could be increased by increasing the clock frequency. However, changing all interfaces, which is necessary for this, is only possible over a very long term. A transition solution is required which allows the gradual exchange or further extension using new interfaces.   The basic concept is the use of switching elements, the inputs and outputs of which can be switched individually between two transmission rates. Example: a frame structure which is based on the lowest transmission rate is used as a basis. Within such a frame, signals with the highest transmission rate can also be temporarily stored and time-converted. Provision is made for 4 Mbit/s and 32 Mbit/s. The advantage is that it is easily possible to combine several channels into higher-capacity connections (N x 64 Kbit/s).   The higher transmission rate is only used when actually required. This reduces the power dissipation and the interference radiation. <IMAGE>
