Patent DE-4116324-A1 (DE)
Title: Thermal press for (e.g.) textiles - uses inflatable membrane to raise workpiece to heating element on upper press plate
Inventor: SIEWERT INGO DR
IPC: B30B5/02
Filed: 1991-05-16
Abstract: The upper and lower press plates (2,3) of non-conducting material carry support plates (7) also of non-conducting material. Between the end edges of the upper support plate is stretched a thin non-conducting sheet with a resistance coating of low thermal capacity. This may be of electrodeposited copper or aluminium. An airtight cavity (4) is formed between this sheet and the hollow in the support plate behind it, and a series of conical insulators (8) keeps the sheet horizontal. The cavity has a reflecting coating. An option is for the upper support plate to be water-cooled. The lower support plate has a membrane (9) stretched across it of silicon rubber. Below it is a separating plate (14), supported by insulators enclosing an airtight cavity with reflexing sides, but this can be dispensed with, the insulators supporting the membrane directly. The workpiece (13) is supported on a carrier between the press plates. The membrane is inflated to bring it into contact with the heating element above it. ADVANTAGE - Low thermal capacity; direct heating of work material; simple operation.

Title: Comb-line filter with two capacitors in series - which constitute voltage divider between stripline resonator end and second earth plane for input and output
Inventor: GRAF ULRICH DIPL ING
IPC: H01P1/203
Filed: 1991-12-06

Abstract: A dirt filter (9) is connected into a water-supply line (8), which filter has a mechanical filter element through which the water passes and which, on the side against which the water flows, is enclosed in a filter housing (9'). The filter housing (9') is connected, via a first controllable shut-off valve (10.1), to a first drainage-water flushing line (11.1) opening into a drainage-water channel (21), with the result that the filter element can be flushed free of dirt by opening the shut-off valve (10.1). In the course of the water-supply line (8), a pressure tank (20) is connected downstream of the dirt filter (9), water inflow being carried out in the upper tank part and water outflow being carried out in the lower tank part. The pressure tank (20) is connected, at the top, to a gas-outlet line (22) with a precision air-release valve (2) and, at the bottom, to a flushing line (18) which is connected, via a second controllable shut-off valve (10.2), to a second drainage-water flushing line (11.2) which likewise opens into the drainage-water channel (21). Impurities in the water which have not been retained in the dirt filter (9) are either deposited on the base of the pressure tank (20), from where they are floated out when the shut-off valve (10.2) is opened, or rise in the form of a gas into the gas-outlet line (22), where they are blown out by the air-release valve (2). <IMAGE>
