Patent DE-3908479-A1 (DE)
Inventor: OKUYAMA TOSHIAKI
IPC: A45C5/02
Filed: 1989-03-15
Abstract: A method of injection moulding a hinge comprises inserting a cylindrical core element (12), which has a recess (13), into a mould cavity (14) of a mould (10, 11), and then injecting a moulding material into the cavity to mould a bearing in cavity (14) having a bore wall defined by the outer cylinder surface of the core element (12), and a shaft in the recess (13). By this method there is produced a hinge with the shaft engaged in the bearing bore. Because the outer end of the wall of recess (13) does not contact mould (10, 11) a tangible connecting piece is formed between the shaft and bearing. <IMAGE>
Patent DE-3914493-A1 (DE)
Title: Support for a recording material
Inventor: GABRIEL GERHARD DIPL ING
IPC: G03F7/09
Filed: 1989-05-02
Abstract: The invention relates to a multilayer support (base, carrier, substrate) for the lamination of a recording material having a photocurable polymer layer, where the support has a pigment-containing binder layer on the surface facing the photocurable polymer layer and a release layer, which simplifies detachment from a carrier coated with a contact adhesive, on the surface facing away from the photocurable polymer layer. This support is characterised in that the release layer contains, as binder, a) a polyurethane to which a pigment has been added, or b) a mixture of a polyurethane and a polyacrylate to which a pigment has optionally been added. If, before the lamination of the recording material, this support is laminated with the reverse of a thick cardboard or a correspondingly thick plastic film, particularly favourable registration retention is ensured, which has an advantageous effect on the reproduction results of the print image.

Title: Successive active carbon walls - continuously remove solvent from air with desorption from opposite face
IPC: B01D15/00
Filed: 1989-06-06
Abstract: Sorptive active carbon for the molecular sepn.  of solvents from air is formed into walls which adsorb solvent from the mixt. at one face, with desorption from the opposite face after migration of solvent between the faces. Desorption is effected by reduced pressure adjacent the exit surface, and can be aided by slight temp. rise. The walls may be concentric rings in a cylindrical housing with an axial gas outlet pipes. In an alternative the walls are transversely disposed in a cylinder and have indented flow passages at successively diametriclly opposed edges to form a meander path for air moving between the cylinder ends. Permeable support layers have the same configuration as the adsorber walls, and may be integral with them. ADVANTAGE - Self-contained separator works continuously, without external energy supply, has no moving parts, and cannot thermally break down the solvent.

Patent DE-3926939-A1 (DE)
Inventor: ROSENBERGER WINFRIED DIPL ING
IPC: H04N7/088
Filed: 1989-08-16
Abstract: 2.1 Electric time-controlled combination locks for entertainment electronics devices are known. To block the reproduction or the reception of a particular television transmission at the television receiver (childproofing), the user enters an additional codeword with the data which are required for programming for reception of the television transmission. Data and codewords are entered into a memory and a control device arranged in the set compares the stored codewords or data with the currently entered codeword or received data of the television transmission. 2.2 To enable even an unskilled user to block the reproduction of particular television transmissions in a simple manner, the corresponding data are automatically taken by means of data decoder or videotext decoder and, together with the codeword entered by the user, supplied to the memory. The control device also takes into consideration transmitter-controlled reprogramming or also provides for automatically blocking sets of a combination of sets. 2.3 The novel device utilises transmitter-controlled aids in a surprisingly simple manner for preprogramming a receiver in conjunction with childproofing. <IMAGE>
Patent DE-3930508-A1 (DE)
Title: Road surface finishing construction for downhill sections - has higher roll resistance factor than normal to relieve loading on vehicle braking system
Inventor: DESCHLER GERHARD DIPL ING
IPC: E01C9/00
Filed: 1989-09-13
Abstract: The finishing coats are for the surface of downhill stretches of roads. The coatings have a higher roll resistance factor  compared with the normal factor, and so far as possible are adapted to the inclination or slope of the road. The increased rolling resistance may be combined with an increased coefficient of friction between the road surface and the tyres, to avoid the risk of skidding or locking up wheels under severe braking. USE/ADVANTAGE - Modified road surface relieves the strain on vehicle brakes by providing better grip and by increasing the rolling resistance.

Patent DE-4009995-A1 (DE)
Title: Engine mounting for vehicle - incorporates elastic support about torque roll axis and stiffened support for static force
Inventor: FATEHPOUR EDISON
IPC: B60K5/12
Filed: 1990-03-28
Abstract: The engine and transmission hare supported on two main mountings (6,7) which define the torque roll axis and can swing about this axis with soft damping. The static force (moment) due to the reaction from the wheels is absorbed by a stiffer spring force for stability. The softer damping isolates the vehicle from engine vibrations e.g. when idling. The layout of the damping depends on the transmission orientation, with the torque roll axis at different alignments to the static axis for different drive unit orientations. The combination of the two support systems provides a quiet running vehicle. USE/ADVANTAGE - Improved comfort e.g. for diesel vehicles.

Title: Removal of solid material content from fibrous suspensions - comprises filtering waste water, drying any solid to specified dry-matter content and mixing with sludge obtd. from further solid-liq. sepn.
Inventor: EICHLER DIETRICH DR
IPC: C02F11/12
Filed: 1990-04-26
Abstract: A new procedure for removing solid material from fibrous suspensions, in which the waste water is further cleaned by a liq.-solid sepn., is characterised by the drying of the fibrous solid material in the suspension to a dry-matter content of 35-45 percent, and the mixing of this material with the sludge produced in the further treatment of the liq. which has been sepd.  from it. The initial sepn. may be carried out using a rotary drum filter, and the bio-sludge produced in a subsequent microbiological treatment of the sepd. liq. may be blended with the dried material in a mixing machine. Alternatively, the initial sepn. may be performed in a screw press separator, and the sludge sepd. from the removed liq. in a decanting or flotation process, with or without the use of a flocculating agent, may similarly be blendd with the dried material in a mixing machine. USE/ADVANTAGE - Used for treating suspensions such as industrial and agricultural waste water. The foreign material content in the liq. passing to the waste water treatment plant or being used for spreading on the land is reduced, so that energy costs are reduced, nutrients are recovered, and the contamination of the land is reduced.
