Patent DE-3825584-A1 (DE)
Inventor: HOENEL MICHAEL DR
IPC: C08G18/58
Filed: 1988-07-28
Abstract: The invention relates to paste resins based on epoxide compounds, containing (a) specific quaternary ammonium groups, (b) OH groups and (c) isocyanate radicals bonded to the epoxide compound, of which at least 10 mol% are derived from a long-chain, monofunctional isocyanate having at least 8 carbon atoms, the mean molecular weight (Mn) of these paste resins being 500 to 10000. 
<??>In addition, the invention relates to the preparation of these paste resins, to their use for pigment pastes and to these pigment pastes. Water-thinnable paints, in particular electrodeposition paints, which contain the pigment pastes according to the invention give defect-free surfaces and comparable coating thicknesses even on different substrates.
Patent DE-3826169-A1 (DE)
Title: Hydro-jet freeze-boring method and apparatus
IPC: E21B7/18
Filed: 1988-08-01
Abstract: The hydro-jet freeze-boring method utilises the high-pressure water technique in the kbar range for the rock excavation and, due to the placement of an ice seal in the cooling-zone area of the drilling implement between borehole wall and drilling implement as well as in the cuttings delivery pipe, replaces the disadvantageous borehole flushing by an ice/solid delivery. After rising through the cooling zone of the cuttings delivery pipe, the ice/stone column is separated segmentally via high-pressure air and is catapulted upwards as in an air gun. Apart from the delivery of solids, the ice seal enables drilled cores left behind to be fractured in a form suitable for delivery and also permits active control of the drilling implement and directional adjustment and widens the drilling-depth horizon.

Title: Gearing, particularly for a windscreen wiper system on motor vehicles, and a wiper motor with a gearing of this type
Inventor: RIENHARDT HANS PETER
IPC: F16H55/28
Filed: 1988-08-23
Abstract: The invention relates to a gearing, particularly for a windscreen wiper system on motor vehicles. The gearing has a rotating crank, a rack articulated on the crank, a rotatably mounted pinion with which the rack meshes and a guide which is pressed against the rack by spring means and holds the rack and the pinion in engagement, at least radially. In a gearing of this type, the backlash between the rack and the pinion is to be largely eliminated, by simple means and without significant losses in efficiency. This is achieved by virtue of the fact that the guide has at least one roller, this roller resting resiliently against the rack.
Patent DE-3830262-A1 (DE)
Inventor: WEISS HERMANN
IPC: F16D3/10
Filed: 1988-09-06
Abstract: The invention relates to a steel coupling having at least one eccentric spring-layer packet 17a,17b which holds the coupling halves 13a,14 in the untensioned state with axial spacing, the spring-layer packet being inclined at an acute angle relative to the normal of the axis, so that, when there is a small axial displacement of the coupling halves 13a,14 relative to each other, an angular offset of comparative size is produced. This makes it possible to compensate load-dependent angular displacements, for example in circumferential registers of rotary printing machines. Fig.3 is intended for the abstract. <IMAGE>

Patent DE-3842480-A1 (DE)
Title: Planar polymer optical waveguide
Inventor: SULTAN MICHEL F
IPC: H04B10/2507
Filed: 1988-12-16
Abstract: The concept of nets (networks) of planar polymer optical waveguides is developed, by means of which low costs and large-scale complete integration can be achieved. These nets are intended, above all, for use in motor vehicles, including data connecting nets (in particular multiplexed nets) having sensors, switches, and display possibilities. The concept can, however, be applied to other fields as long as the overall length of the net is not more than a few metres. The basic idea consists in that a thin film (24) of transparent plastic material, such as e.g. PMMA (polymethacrylate), polycarbonate, or polystyrene is "cut up" into a network having optical connections, couplers, sensors etc. In this way, instead of a one-dimensional fibre-optic network a two-dimensional optical waveguide net is produced which offers great possibilities in terms of design and dimensioning of the light guidance. <IMAGE>

Patent DE-3906064-A1 (DE)
Inventor: BOEHLER HARALD GEBHARD
IPC: F26B25/00
Filed: 1989-02-27
Abstract: The pollutant-containing drying waste gas from a drier 26 for wood chips or wood fibres is washed in a washer 1 and thus largely freed of pollutants. Aerosols are removed in a downstream aerosol precipitator 16. A solvent having a higher boiling point than water and a low vapour pressure is used as the washing liquid, which is circulated and cooled and thus in turn cools the drying waste gas at least down to the dew point of the water vapour. The amount of condensate arising from the drying waste gas can be controlled by more or less intensive cooling of the washing liquid. Similar comments apply to the heat recovery provided, in which especially the heat of condensation which arises is utilised. The recovered heat is preferably used for predrying the wood chips or wood fibres. <IMAGE>

Materials for sealing the load bearing elements are waxes, gels, soft resins or elastomers which be EVA, PU or oil-free polyamide based hot melt adhesives. USE/ADVANTAGE - Prevents tensile strength variation in optical cables caused by temp. changes.
