Patent DE-3816894-A1 (DE)
Title: Process and apparatus for producing construction elements from textile carpet waste material
Inventor: GIESEN KARL
IPC: B29B17/00
Filed: 1988-05-18
Abstract: In the known process, rod- or plate-shaped construction elements are produced from textile carpet waste material by dividing the latter into chips, granulating, and providing the granules in succession with the two components of the polyurethane acting as binder. This mixture is compression-moulded and cut into the desired lengths. To obtain a more convenient process which leads to a product of great uniformity and strength, it is proposed that the carpet chips be initially ground and then surface-melted, before being simultaneously provided with the two components of a latently further-crosslinkable polyurethane. The mix is then compression-moulded and the moulding is finally subjected to a concluding heat treatment which is used to cure the polyurethane to form a thermoset.

Inventor: WALTER DIETER
IPC: B60J11/00
Filed: 1988-05-28
Abstract: In the case of a sun-shielding device for motor vehicles with a housing and a shielding sheet which can be pulled out of the housing, the housing comprises an extruded profile which on its lower side has at least one dovetail-like longitudinal groove which runs continuously in the longitudinal direction of the profile, is open downwards and in which at least one holder, which is to be secured on the boot lid, engages displaceably by means of a dovetail-like projection. There are preferably provided two longitudinal grooves and two U-shaped holders which in each case sit on a supporting plate bent around in a hook shape. The supporting plates are connected to one another via a tie rod and are clamped against the edges of the boot lid. The shielding sheet sits on a roller which is mounted in shaft sockets in end-side covers of the extruded profile.

Title: Arrangement for sucking off sludge deposits, in particular for cleaning aquaria
IPC: B01D21/24
Filed: 1988-07-16
Abstract: The arrangement for sucking off sludge deposits which have formed on the surface of sand or fine-sand bottom structures, serves in particular for cleaning aquaria. It has a suction hose (a2) on a nozzle head (A) which is provided with a longitudinal slotting (4, 4.1, 4.2). As a result of the longitudinal slotting, a first axially oriented sucking cross-section of the nozzle mouth (5) is extended by a second, laterally oriented suction cross-section. A sucking-off tube (C) is connected to the nozzle head (A) via an adjusting pipe (B) which is mounted with a sealing fit but longitudinally displaceably in the longitudinal duct (1) penetrating the nozzle head (A) including suction hose (a2), the suction per surface unit of the effective suction cross-section being adaptable to the bottom structure by the degree of overlap (b20) of adjusting pipe (B) and longitudinal slotting (4, 4.1, 4.2). The adjusting pipe (B) is provided with a scale (b2), by means of which the degree of overlap (b20) or lack of overlap of the adjusting pipe (B) with regard to the longitudinal slotting (4, 4.1, 4.2) and thus a measure analogous to the suction per surface unit at the nozzle mouth (5) of the suction hose (a2) can be read off. <IMAGE>

Title: Method for improving the cost/benefit ratio in waterborne tankers
Inventor: KUECKENS ALEXANDER
IPC: A01G7/02
Filed: 1988-12-07
Abstract: A method for improving the cost/benefit ratio in waterborne tankers is envisaged, in the case of which the tankers which transport crude oil, for example, from supplier countries to oil-consuming countries are loaded with fresh water, such as lake or river water, which is unfit for human consumption for the return journey and transport it to countries containing desertlike or arid regions which cover a relatively large area. The water transported by the tankers is finely impregnated with carbon dioxide and is used to irrigate crops which are planted in deserts or arid regions of this type in order to ensure that the plants can grow in these conditions under conditions which are as favourable as they are for crops grown in humus soils.
Patent DE-3842336-A1 (DE)
Title: Process and apparatus for recovering an organic solvent
Inventor: FUEHRING HEINRICH DIPL ING
IPC: C23G5/04
Filed: 1988-12-16
Abstract: The invention relates to a process for recovering an organic solvent during the drying of a fabric treated with the solvent in a dry cleaning machine or the like and an apparatus to carry it out. To recover the solvent, in such machines, a circulating air stream, after heating and contact with the fabric, is then cooled, reheated and again circulated over the fabric. In this case a part-stream is branched off from the air circulation circulating over the fabric in the region between cooling and the renewed contact with the fabric and, in a further circulation proceeding via an adsorber, is reintroduced into the drying circulation before being cooled again. In order to improve the efficiency of the recovery, according to the invention, during the drying, the part-stream branched off is first vigorously heated after its branching off in order to achieve an efficient desorption of the solvent in the adsorber and then without heating is passed directly to the adsorber after cooling, after its exit from the adsorber it being returned back to the drying circulation.

Patent DE-3920787-A1 (DE)
Inventor: BRANDELIK ALEXANDER DR
IPC: G01N22/04
Filed: 1989-06-24
Abstract: The invention relates to a method and a device for determining the volumetric water content of mineral and/or organic mixtures by means of dielectric measurements. 
<??>The water content is therefore determined without an elaborate mixture-specific calibration. 
<??>For this purpose, an electromagnetic wave is applied to measuring electrodes of a probe and their complex reflection factor is measured. Then the water contained in the mixture is frozen out by suitable means and the measurement is repeated. From the two measured complex reflection factors and the known permittivities of water and ice, the water content of the mixture is then determined using a calibration curve specific to the apparatus.

Title: Removing single sheets from stack - involves gripper drawing sheet away horizontally and into deflection channel
Inventor: HERRMANN HERBERT
IPC: B65H1/02
Filed: 1989-10-04
Abstract: The device for taking off each topmost sheet from a stack has a gripper element through which each top or front sheet of the stack (6) is seized and moved horizontally away from the stack (6) through a shaft (13) which opens at its lower side into a deflection channel (22) which is vertical in its lead-in area (23). The extension of the deflection channel (22) alters constantly from the upright lead-in area (23) to the end area (24) which is aligned in the conveyor direction (11) of the conveyor belt (3) and ends just above the conveyor belt (3).

Title: Shower bath outlet head - has flexible disc in outlet which is deformed by water pressure and prevents build-up of lime deposits
Inventor: WAGNER FRIEDRICH DIPL ING
IPC: B05B15/528
Filed: 1990-12-10
Abstract: The shower head (12) of a shower bath has its spray head formed by two rigid plates (23) with a disc of  elastically flexible material clamped between them. Each rigid plate has a ring of holes (24) which coincide with each other. The flexible disc (26) has a ring of holes (25) on the same pitch circle as the holes but of smaller dia. and aligned with the holes.
