Title: Vacuum transfer moulding station and process for heating a plastics film, especially for manufacturing a casting mould moulded under vacuum
Inventor: MEIER HELMUT DIPL ING
IPC: B29C51/42
Filed: 1982-10-28
Abstract: The invention can be used for vacuum processes and generally in the heating of plastics films. Whilst the aim can be seen as reducing the energy input and as reducing heating times and as avoiding quality defects, the object consists in achieving a uniform direct heating of the plastics film depending on the film grade used with simultaneous measurement of the film temperature, with an application being permitted even for highly contoured designs. This is substantially achieved by designing the film heating device as a controllable height-adjustable contact heater, the heating surface being air- permeable and having an anti-adhesive coating on its underside. The contact heater is surrounded by a housing provided with a thermal insulation, on which a connection is provided for a vacuum source. A metal plate of air-permeable design is provided as heating surface, on the uncoated surface of which heating elements and temperature sensors as well as a reflector covering these are disposed. <IMAGE>

Title: Sizing sleeve for vacuum sizing of plastics extrudates and process for the manufacture thereof
Inventor: DEISENBERGER GUENTHER
IPC: B29C48/90
Filed: 1983-03-02
Abstract: The sizing sleeve serves for vacuum sizing of tubular plastics extrudates emerging in the plastic state hot from an extruder. It consists of an assembly of rings disposed concentrically at a distance with uniform internal diameter, which are held by external ribs extending parallel to the axis of the ring assembly. The ribs are fastened to the rings by weld points or hard solder points. A sizing sleeve of this kind is manufactured by first externally machining into a tube grooves of a width which corresponds to the intended ring spacing and of a spacing which corresponds to the intended ring width and at the base of which the pipe has a smaller external diameter than the desired internal diameter of the finished sizing sleeve, by fixing rods externally on the tube parallel to the tube axis by welding or hard soldering and by then finally machining the tube to the desired internal diameter.
Patent DE-3308146-A1 (DE)
Title: Relief valve
Inventor: GROB ALFRED
IPC: F16K17/10
Filed: 1983-03-08
Abstract: The relief valve (10) in a hydraulic system has a spool (32) with a pilot control valve (50). In the event of a brief excess pressure in the hydraulic system or a load (25), pressure medium is released only via the pilot control valve (50) whereas, in the event of a more prolonged excess pressure, the spool (32) of the relief valve is moved, with the pilot control valve open, to a position in which the high-pressure side (15) is connected directly to the low-pressure side (29). In order to avoid pressure fluctuations which act on the control spool (32), a differential-pressure valve (42) arranged upstream of the pilot control valve (50) is provided in addition in the said spool. A small pressure difference of about 3 to 4 bar prevails at the differential-pressure valve. In this way, exact control of the spool (32) is achieved for relief of the hydraulic system in the event of a relatively prolonged excess pressure. <IMAGE>

Title: Process for producing bricks from carbon-containing clay
Inventor: GOLKE HEINZ DIPL ING
IPC: F27D7/02
Filed: 1984-02-25
Abstract: The clays used for burning bricks contain carbon-containing components which have to be removed before the actual burning process by oxidation at 600 to 900 DEG C. In order to accelerate this oxidation, a gas at least enriched in oxygen is additionally introduced into the kiln in the range of the temperatures mentioned. In order to improve this process, the oxygen-rich gas is fed through corresponding oxygen burners (7) operated with oxygen excess. The high surge of the oxygen fed in this manner effects a rapid and extensive homogenisation of the oxygen partial pressure in the kiln section affected and a corresponding quality improvement. The process is especially advantageous for tunnel kilns. <IMAGE>
