Patent DE-3903627-A1 (DE)
Title: Adjuster having at least one drive part in the form of a memory element
Inventor: FELDMANN WOLFGANG DIPL ING
IPC: G12B1/00
Filed: 1989-02-08
Abstract: The energy supply to a heatable memory element is intended to be designed in such a way that overheating is avoided during the heating process for generating the desired shape change. For this purpose, it is proposed to transmit the deformation movement of the memory element (2 or 3) to a slide (1) serving as displacement part, of which the displacement movement in the course of the deformation of the memory element breaks the connection to the heating energy source in the heating position. Returning the slide (1) into a starting position corresponding to an initial setting of the memory element is carried out by means of a reset unit. <IMAGE>

Title: Door stop with internal catch - prevents door from being slammed using inertia of piston to operate catch
Inventor: HOFMANN RAIMUND
IPC: E05F5/08
Filed: 1989-07-12
Abstract: The door stop for preventing the violent closing of a door consists of a cylindrical housing (2) for a main piston (3).  When the door is closed slowly the main piston (3) presses against the spring (16) and at the same time compresses the air inside the cylinder (2) so that a gradually increasing force is applied to the door. When the door is closed violently the inertia of the inner piston (5) holds it back while the main piston (3) moves into the cylinder (1). The locking device (6) is then pressed over the conical end of the inner piston so that the arms (19,20) are pressed outwards and the claws (21,22) pass through holes (13).  The claws then stop the movement of the main piston when they abut against the end face (31) of the cylinder (2). USE - Door stops designed to prevent violent closing of door.

Title: Hydride use to reduce nitrogen oxide cpds. in combustion exhaust gas - after oxidising combustible components with air, reducing environmental pollution
IPC: B01D53/56
Filed: 1990-01-12
Abstract: Process and appts. using hydride, pref. in solid or gaseous form, involves oxidn. of the combustibles in combustion exhaust gases with air and redn. of the N` in the exhaust gas by adding hydride into the exhaust gas stream, with or without heating. Hydride gas or liq. is added to the exhaust gas stream in a series of combustion chambers operating by the Carnot cycle, pref.  after oxidn. The hydrides are sepd. from solids by heat directly in the exhaust gas stream from hybrid carriers. A furnace and tile kiln insert consists of catalyst honeycomb, which forms the combustion chamber. The outer skin and honeycomb behind this are filled with sand as heat store. After oxidn., the NOx in the flue gas is reduced to N2 and H2O by hydride released from carriers. MgH2, monosilane and silanes are used as hydride carrier and for NOx redn. and also for m absorption of HF, HCl and HSOx with Mg or Si as reaction prod. and the values are recovered. USE/ADVANTAGE - The process is claimed esp. for redn. of NOx in the exhaust gas stream from combustion in the Carnot cycle, 2-stroke engines and diesel engines. Labmda probes, recirculation of the flue gas and NOx catalysts are unnecessary. The process reduces environmental pollution.

Title: Thermoplastic FRP threaded rod - consisting of main body reinforced with long fibres and skin contg. only short fibres it has thread formed by cold rolling
Inventor: KRUEDENER RUDOLF PROF DIPL ING
IPC: B29C48/13
Filed: 1990-05-22
Abstract: Screws or threaded rods are made of fibre-reinforced thermoplastics and their mechanical properties are made optimal by using long fibres (5-10 mm) in the interior and short fibres (0.1-0.15 mm) in the outer part and by cold rolling the thread into the outer skin layer. An alternative to the short fibres is glass microspheres. Pref. the prods. are circular section rods made by coextrusion in which thermoplastic granules with the long fibres are fed into the extruder for the core material (1) whilst a second extruder produces the short fibre-filled skin (2). A twin-component coextrusion extruder can be fed with both mixes so as to produce the desired coaxial system. The core of the rods is primarily thus made with longitudinal fibres, which transmit max. loads but show minimum cold flow. The short-fibre skins transmit shear forces in the threads formed and their fibres permit cold flow. By rolling the thread cold the strength limits in the thread are considerably greater than those of cut threads. Moreover the cold working produces a certain strengthening in the matrix. ADVANTAGE - The prods. have highest feasible mechanical strength.

Inventor: BUBIK ALFRED DIPL ING DR
IPC: D21F9/00
Filed: 1990-08-25
Abstract: The dewatering apparatus for a twin-wire paper machine is constructed in such a way that, after the two wires (1, 2) are first brought together at a forming cylinder (7), a uniform pressure is exerted on the suspension layer between the wires.

Inventor: HEHNER REINHARD
IPC: B65H35/02
Filed: 1991-01-28
Abstract: The method of winding up lengths of material (1) esp. of paper or carton, onto sleeves involves the length of material being pulled off a storage roller against braking force and cut lengthwise into separate lengths which are then wound onto separate reels (19,20). Part of the tensile stress required for winding the material onto thhe separate reels (19,20) is applied by at least one driven support-roller (8) on which the separate lengths of material rest.

The tensile stress is estimated so that the ratio of the torques of the guide-head drive mechanisms of each reel (19,20) can be adjusted according to the ratio of the reel-widths. ADVANTAGE - The tensile stress of the rolls of material being wound is exactly controlled.
