Patent DE-3936496-A1 (DE)
Inventor: REIBER ERWIN DIPL ING
IPC: B29C48/09
Filed: 1989-11-02
Abstract: On a tube extruder head there is mounted a motor-driven screwing device (37) pivotally about the extrusion axis and radially adjustably in such a way that it can be brought into engagement with each of the centring screws (17) for radial adjusting of the nozzle (9). The actuators and drive motor of the screwing tool are controlled by a computing and controlling unit (63), to be precise in dependence on the differences in wall thicknesses measured by a wall-thickness measuring device (45) at a number of points on the circumference of the tube. This permits automatic centring in a closed control loop. The entire apparatus can be retrofitted on existing extruder heads.

Patent DE-4000752-A1 (DE)
Inventor: ROGERS WILFRIED DAVID
IPC: E05B65/20
Filed: 1990-01-12
Abstract: In a central locking system, the electric actuator (16) which enables the release of each latch is connected to a primary locking lever (12) having locked and unlocked positions. A secondary locking lever (13) is arranged for manual operation and a load transfer element, such as a spring, connects the two locking levers (12 and 13) to permit the transfer of a limited load from the secondary locking lever (13) to the primary locking lever (12).

Title: Waste gas filtering and cleaning - by passage at controlled velocity through moving filter and sorbent bed
Inventor: NOETH GEBHARD DIPL ING
IPC: B01D53/74
Filed: 1990-01-28
Abstract: Particulate, gaseous and toxic noxious materials and/or fumes are removed from waste gases and/or flue gases, which also contain water vapour and air, by passing the gases through a gas permeable granulate filter body to cause sepn. and collection of the particulates and simultaneously physical, chemical and biological deposition of the gaseous noxious materials, the gases being passed transversely through the filter body (opt. contg. catalysts and additives) in the form of a bed moving downwardly within a reactor. The novelty is that (i) the bed is formed of filter granulate (e.g. quartz gravel) and granular or pulverulent adsorbent (e.g. active carbon) and sorbent (e.g. CaCO3, Ca(OH)2, Fe2O3, Al2O3, MgCO3 and the like) in solid or porous opt. doped (e.g. with copper oxide and acetylactone), the bed being confined by perforated guides at the inlet and outlet sides for the horizontal gas stream; (ii) the gases are passed through the bed with non-uniform filter velocities, the inlet and outlet guides having slatted baffles of different flow cross-sections, so that the gases enter the inlet side at high velocity and leave the outlet side at low optimal velocity; and (iii) the correct or calculated filtration velocity between the inlet and outlet sides is continuously controlled so that dust of different fractions corresponding to the gas velocity deposits uniformly over the entire flow depth of the filter cross-section. USE/ADVANTAGE - The process is used esp. for removing solid particles and aerosols from high temp. gases from special waste (e.g. used oil) incineration, but can also be used to separate extremely fine (0.01-1 micron) sticky particles, e.g. oil residue-coated soot particles.

Title: Pressure relief valve for air conditioning system - is held closed by a pre-stressed torsion bar spring
Inventor: WECK FRANZ DIPL ING
IPC: F24F11/00
Filed: 1991-08-02
Abstract: The valve is installed in the duct which is provided with a transverse wall (2). The wall has two openings (3, 4) which are closed by valve discs (10) and (12) respectively. These discs are attached to the ends of arms (9, 11) which are connected to a shaft (7). The shaft functions as a torsion bar spring and exerts a moment on the arms which tends to hold the discs in their closed positions. When the maximum working pressure is reached the pressure on the larger disc (12) overcomes the moment exerted by the pressure on the smaller disc (10) together with the moment exerted by the torsional pre-stress in the shaft. ADVANTAGE - Maintains an effective seal until it opens at the intended pressure.

Title: Introducing small particles material into underground caverns -  involvespneumatic closed conveyor system with preliminary separator
Inventor: BUECHNER HARM-PETER DIPL ING
IPC: B65G53/06
Filed: 1991-08-14
Abstract: In order to introduce small-particled materials such as dust or sludge waste into underground caverns a conveyor air stream is guided in a closed circuit so that it passes from the underground cavern (2) through a dust separator (51) and back to the compressor. The downward conveyance can be achieved through a conveyor tube circuit mounted in a protective tube circuit wherein the conveyor air is returned through the annular space between the two tubes. The pressure side of a compressor can be connected to a dosing unit for the material and to a conveyor pipe opening into the cavern. Two conveyor pipes opening into the cavern can be connected alternately to the dosing unit and suction side of the compressor through valve-controlled connecting pipes.
