Patent DE-4122546-A1 (DE)
Title: Fabric fluid treatment - is given an initial pressing before passing through diffusion stretch with the treatment roller
Inventor: BRAUN FRIEDHELM
IPC: B05C3/12
Filed: 1991-07-08
Abstract: To treat a fabric with a fluid, e.g., bleaching / dyeing / finishing, etc., the surplus fluid is removed at the entry by pressing the surface of the fabric against the treatment roller. A diffusion stretch is between the initial pressing action and the final pressing, where the material is moved to and from the roller surface. One or more intermediate press actions are pref. applied to the fabric surface between the initial pressing stage and the diffusion stretch, with a rapid and short press movement on the fabric against the roller. After the first pressing, the fabric has a moisture content of 100-300%, and 70-220% after the intermediate pressings to pass into the diffusion stretch. At the final press stage, the fluid content is reduced to 50-120%, and extracted fluid is returned to the entry zone. The time to diffuse the fluid through the fabric is constant, with different travel speeds to allow for different fabric lengths. ADVANTAGE - The active chemicals are controlled and applied to the material for the best effect, using a small fluid supply volume. When the fabric passes to the next treatment stage, it has a low residual moisture content.

Title: Compressor process to clean vehicle exhaust gases - comprises compression stage, then compressed gas is passed through to absorption filter, cleaned, expanded back to atmospheric pressure and released
Inventor: KREUTZMANN PAUL DIPL ING
IPC: B01D53/14
Filed: 1991-09-18
Abstract: In a process to clean exhaust gases contg. hydrocarbon gases or vapours, preliminary cleaning is effected in a contraflow exchange column by a cooled fluid absorption medium. The absorbent consists in part of fluid from which the effluent has been evaporated. In a subsequent absorption stage, the coarsely-cleaned exhaust gases pass through a regenerated absorption filter. The absorption process stage is preceded by a compression stage in which the exhaust gas pressure is raised to at least 2.5 bar absolute; coarsely cleaned exhaus gases are passed through the absorption filter at increase pressure and the gases thus cleaned are then expanded back tû atmospheric pressure and released; the absorption filter i regenerated by means of an expansion assembly, with the resultin gases being returned to the compressor stage. USE/ADVANTAGE - The process facilitates removal of high concns. of harmful substances from vehicle exhausts to a level which meets the legal requirements, with simple equipment and at low cost.

Title: Apparatus for seam detection and positioning for laser welding - uses search lasers and working beam focussing optics
Inventor: ARLT ALFRED G
IPC: B23K26/04
Filed: 1992-02-08
Abstract: The position of a joint (1) relative to the working point of a working laser beam (9) is determined preferably by means of the measuring beam (14) of a He/Ne search laser (13). The reflection of this beam is let into the existing path of the working beam (9). Preferably a deflecting or decoupling mirror (19) - which has hole or is partially transparent is installed behind the welding head (3) to caputre this reflection by means of a detection system consisting of a collector lens (21), a filter (22), a photo diode (23) and a light-tight housing (20).

The mirror (19) has a hole with a diameter corresponding to the measuring beam (14). It is swivelled out of the main beam path after the shutter (10) is opened. As an alternative, the mirror is located (without swivelling capacity) directly in front of the search laser. As a further alternative, the fixed mirror - with a hole diamater slightly larger than the working beam - is located in the path of the working beam. The filter (22) is either a colour or interference filter. USE/ADVANTAGE - In the laser welding technology. It allows utilisation of search lasers which are normally present laser welding installations, and (in contrast to known system) requires no special protection measures against splashes, smoke etc..

Title: Electroless metallisation of microporous plastics film in metal ion soln. - giving mechanical stability, strong adhesion, corrosion resistance and high conductivity, e.g. for capacitor or thin film battery
Inventor: BESENHARD JUERGEN OTTO PROF DR
IPC: H01M4/80
Filed: 1992-05-05
Abstract: In the metallisation of plastic films, microporous films (I) with a pore size of 5-1000 nm and thickness of 5-500 microns are subjected to electroless metallisation on one or both sides in a soln.of the corresp. metal ions. (I) pref. consists of (halogenated) polyolefin. (I) are pref. premetallised and then the metal film is enhanced by electroplating. (I) metallised on one side may also be electroplated on the back by rivet-like anchoring through the pore structure remaining on the back. In this case, the electroplating pref. extends through the pore structure on the back until the metal protrudes from the pores and beyond the plane of the surface of the film. USE/ADVANTAGE - The metallised films are useful for e.g. electrolytic capacitors and thin film batteries. They are mechanically stable and the metal adheres well, even in aggressive solns. and has high conductivity. In an example, hydrophobic microporous separator films e.g. `Celgard 24000' (RTM; pores sizes 20-50 and 100-200 microns; porosity 40%) were activated 1-5 min. at 40-45 deg. C in an activator soln. prepd. by dissolving 6 g/l NaOH and concn. `Neoganth' (RTM) soln. in an amt. giving 0.2 g/l Pd(2+), stirring 2 h at 50 deg. C, allowing to cool and adjusting to pH 10.5-11. After rinsing with water, redn. was carried out for a least 1 min. at room temp. in an aq. soln. of 1 g/l NaBH4, 5 g/l NaOH and 3 ml/l `FC 128' (RTM). The film was rinsed, then metallised 5 min. at 30-35 deg. C in an aq. Cu plating soln. contg. 40 ml/l `Naviganth HC' (RTM), 8 g/l NaOH, 0.4 ml/l stabiliser, 15 ml/l reducing agent soln. and 3 ml `FC 128' (RTM: fluorinated surfactant) soln. in MeOH, adjusted to pH 12.8-13. A thin, homogeneous, highly lustrous Cu film was formed on both sides, which was bonded well and max. 200 nm thick. The resistance was typically 1 k (in the lengthwise direction). This type of Cu plating did not impair the flexibility of the film. It was then electroplated with Cu, Ni, etc.

Inventor: KREBS RAINER DR ING
IPC: H02H7/26
Filed: 1992-09-14
Abstract: In order to obtain improved triggering properties in a protective device for power supply lines, a protection triggering process is proposed in which at least one signal (i, u) is taken to a filter device (3, 16) and a triggering decision is taken depending on its output signal (SA, Z). If the conditions are insufficient for triggering, the filter properties are altered. The filter device (3, 16) here preferably comprises FIR-filters or filter combinations. In a further embodiment, depending on a change in the output signal, a region of non-sharpness is formed which acts as a triggering criterion.
