Title: Coke quenching tower has flue contg. Jalousie arrangement of plates - flushed with water and caused to vibrate reducing solids content of discharge to atmosphere
IPC: C10B39/08
Filed: 1990-04-09
Abstract: Coke-quenching tower, for wet extinguishing of red-hot coke, has a quenching chamber with an outlet flue. In the flue, over its whole cross-section, are frames, casings or racks arranged  above one another and in the form of pitched roofs, each with a ridge in the middle; they containg jalousie-fashion, wooden or plastic plates. The flue has a piped water distribution and flushing arrangement for the plates. The plates (7) are of angle section and have openings at the apex for the holding rods (8) to pass through. Variants specify the angle of the plates (pref. between 110 and 130 deg.) and other details of the plates, holding-rods and flushing arrangements. USE/ADVANTAGE - The tower arrangements reduce, in the interests of the environment, the amount of solids discharged to below 20 g/tonne of coke, which is well below the 50 g/tonne of earlier towers.

Title: Cellulose washing
Inventor: TREU BERNT U
IPC: D21F1/80
Filed: 1990-06-06
Abstract: To wash cellulose, or a cellulose felting, it is carried between two seive belts through a number of stations with pressure and suction while held and clamped between the belts. Pref. the sieve belts travel horizontally, or generally horizontally while the cellulose material is being treated. The suction effect is applied while the sieve belts are at least partially at an angle of 40-60 deg.  between two deflection rollers where the gap between their axes is greater than the deflection roller dia. The pressure action with the washing medium and the suction action are at least partially simultaneous and/or are separated. During a treatment stage, initially there is a simultaneous pressure and suction effect, followed by suction alone. The cellulose material is carried between the sieve belts from a pressure and/or suction unit to the next higher, and similar unit, so that it travels through the units in alternating directions.

Patent DE-4028447-A1 (DE)
Inventor: BURGDORF JOCHEN
IPC: B60T8/36
Filed: 1990-09-07
Abstract: The valve disclosed has a magnetic armature (2) surrounded by a dome-shaped casing (14), the armature executing a reciprocating motion in response to the passage of current through a coil magnet (16) fitted round the casing (14), thus moving the valve needle (1), which forms part of the armature (2) and part of which is surrounded by a core magnet (13), so that the needle fits into the valve seat (3) which is fixed to the valve housing (15). The invention is based on the idea of superimposing a hydraulic control force on the electromagnetic control force, i.e. going beyond merely switching the valve needle (1) electromagnetically and providing a valve-opening function which is independent of system pressure, like that of a pressure-relief or pressure-limiting valve.

Patent DE-4041753-A1 (DE)
Inventor: HUVER THOMAS DR
IPC: C09J175/16
Filed: 1990-12-24
Abstract: The description relates to reactive contact adhesives based on multifunctional macro-monomer compounds (multi-functional macromers) curable in steps by different reaction mechanisms, which may also be present mixed with one-stage reactive mixture components. The new contact adhesives are distinguished in that they contain substituted urethane oligomer compounds as multi-functional macromers which have moisture-hardening isocyanate groups beside olefinically unsaturated radically reactive constituents. These macromer compounds are preferably mixed with reactive components which are preferably mixed with reactive components which are preferably radically curable reactive diluents and/or moisture-reactive isocyanate compounds with a softening and/or cross-linking function. The description also relates to the production of such adhesive mixtures and their use as contact adhesives in the context of a multi-stage curing process in which the adhesive is first applied in a thin layer to the solid surfaces to be joined and then subjected to a first radical curing stage. The reaction of this first stage is preferably triggered by the effect of UV radiation. The adhesive coatings produced have excellent contact adhesive properties and, after the components to be joined have been brought together, cure to the cross-linked adhesive mass under the effect of atmospheric moisture.

Title: Application of coating of graphite to piston - using silk screen printing process which enables thickness to be varied
Inventor: WEIPERT JOERN
IPC: B41M1/12
Filed: 1991-05-15
Abstract: The surfaces of the piston of an internal combustion engine are coated with graphite. The graphite is applied to those surfaces which are subject to wear with the thickness of the coating being increased in the regions subject to the greatest degree of wear.
