Title: Applying flexible coating to profiled surface of flat components - where coating is drawn onto component by membrane, then pressure is applied by stronger membrane fixed to upper press platen
Inventor: SCHULER GERHARD
IPC: B27D3/00
Filed: 1991-04-17
Abstract: Applying a flexible coating to the profiled face of a flat plate component. The component is placed on a press platen and the flexible coating e.g. a veneer is positioned above.

Title: Textile carding machine not requiring buffer stocks - has weighted input through hopper which balances speed of supply
Inventor: HERGETH HUBERT
IPC: D01G23/02
Filed: 1992-08-03
Abstract: A card is fed from a hopper which is supplied continuously with a weighted quantity of fibrous material. In accordance with the requirement of the card, the supply from the weighing system is adjusted so that overloading is avoided, and the speed of handling is determined by the card. The system of the installation consists of a weighing device (4) which runs continuously. The material is drawn through ducting and carried to the hopper (3) by means of a fan (5) which blow the lightweight fibrous material, in a wedge formation along the top of the hopper. This falls into the roller pair (7) at the bottom of the hopper, forming a sheet of web lying on a carbon fibre delivery table to the input rollers (2) of the carding machine (1). As the material settles in the hopper (3) it accumulates to a height (8), blocking the light (9) at several levels, to operate a photo-electrical sensor, which is connected to the controller (6). This in turn accelerators or reduces the speed of the drive to (5). ADVANTAGE - The system is uncomplicated and ensures a continuous run of fibre, without the need for buffer stocks. A balance is attained, avoiding overload or shortage.
Patent DE-4226455-A1 (DE)
Inventor: LEIMKOETTER ULRICH
IPC: G06F9/46
Filed: 1992-08-10
Abstract: The dynamic performance of a communications system largely depends on the capability of being able to handle system tasks having different urgencies. The system tasks are generally handled by interrupt-controlled processes. Since, in interrupt-controlled mode, a chain of administrative routines is running, the frequent use of interrupt control can mean a reduction in the dynamic performance of the system. The method according to the invention remedies this in that the processes handling system tasks change from the interrupt-controlled mode into a cyclically interrogation-controlled mode. <IMAGE>
