Patent DE-3629688-A1 (DE)
Inventor: BOGUSLAWSKI ZBIGNIEW DR
IPC: B01D47/00
Filed: 1986-09-01
Abstract: A process for removing from flue gases, industrial waste gases, exhaust fumes, combustion gases from natural fires, radioactive emissions from nuclear reactor disasters or the like, their dustlike and gaseous impurities (zero emission). After the gas has been cooled to a temperature between 20 DEG  and 60 DEG C and sprayed with water to remove hydrohalogen impurities, an artificial mist of particles smaller than 25  mu m is generated and the gas is maintained in this mist-like state for the time necessary for the toxic substances to dissolve in and react with the mist droplets. The saturated mist droplets are then precipitated by finely spraying the gas flow with a mist-dissolving substance. To form the (active) mist, an aqueous solution of a reagent able to react chemically with the toxic components and to form water-soluble reaction products, preferably a metal hydroxide, ammonia and/or ammonia water, is sprayed into the gas. In a first stage, a solution containing 50 % active substance is used, and in a second stage, a solution containing 30 % active substance. A metal carbide, oxide, hydroxide, or hydrate-forming chemical substance, for example phosphate or the like, is used to precipitate the mist droplets.

The liquid contents leave the pressing chamber (1) essentially via an additional passage (14) which is arranged in the floor of the pressing chamber (1) in the vicinity of the door (8). <IMAGE>
Patent DE-3642262-A1 (DE)
Title: Disengageable coupling
Inventor: HOBERT HERBERT
IPC: F16D25/06
Filed: 1986-12-11
Abstract: Coupling with relief valve. Hydraulic couplings generally have a single feed opening for the pressure medium, which is arranged radially in the drive shaft. This opening generally has a small cross-section and, when the coupling is released, represents a relatively great restriction for the pressure medium flowing off through it. This single outflow opening gives rise to non-uniform flow of the outflowing pressure medium in the pressure space and, as a result, the working piston is often tilted during its return. In order to prevent tilting of the working piston (4) as it moves back into the rest position and to allow rapid release of the coupling (1), the hydraulic cylinder (3) has relief valves (14) arranged in a uniformly distributed manner relative to the axis of the drive shaft (2) and connected to the pressure space (5), these valves having an outflow line (20). The relief valve (14) is provided with a control piston (16) which blocks the outflow line (20) when the pressure space (5) is subjected to pressure and opens the said outflow line (20) when there is a pressure drop in the pressure space (5). The relief valves allow rapid and reliable release of the coupling, which can be used, in particular, for devices which require rapid engagement/disengagement. <IMAGE>

Title: Sprung spikes on winter tyres for motor vehicles
Inventor: WOBST JOSEF
IPC: B60C11/16
Filed: 1986-12-30
Abstract: Sprung spikes can restore normal safety when travelling on black ice and compacted snow. Since the road pavement is no longer damaged when ice and snow are not present, re-approval by the legal authorities can be obtained. Many kinds of simple structures are conceivable, for example, inter alia, single-component spikes of the earlier type to which the suitably soft undersurfaces (for example rubber plugs) are attached or beneath which the said undersurfaces are placed, can be injected into tyre anchorings which are more recessed (in comparison with the past) or metallic multi-component spikes in which case the spikes are anchored in second metallic components and are connected to appropriately acting steel compression springs.

Patent DE-3743091-A1 (DE)
Title: Spindle unit and device for breaking the edges of a workpiece
Inventor: FOEHN SIGISBERT
IPC: B23B31/08
Filed: 1987-12-18
Abstract: Mounted universally movably in a housing is a bearing body. In the bearing body, a shaft with a tool can be rotated. The body is centred by a number of pistons which are distributed uniformly over the circumference and acted upon with compressed air. In the centred central position of the bearing body, the pistons bear against stops fixed to the housing and against the bearing body. On deflection of the bearing body, at least one of the pistons lifts off from the stop and the opposite piston lifts off from the bearing body. It is thus brought about that the tool exerts a force on the machined workpiece which is independent of the exact position of the same. The spindle unit is suitable in particular for automatic edge breaking.

According to the invention this takes place by means of an air spring bellows which is mounted above the central point of the centrifuge. The drive of the centrifuge, in particular however the braking process of the centrifuge, is effected by means of energy-producing DC motors or asynchronous motors.
Patent DE-3744500-A1 (DE)
Title: Ventilation device for motor-vehicle interiors with air feed from above
Inventor: HENNIG KLAUS
IPC: B60H1/24
Filed: 1987-12-30
Abstract: The invention relates to a ventilation device for motor-vehicle interiors with air feed from above, which is characterised in that at least one pipe leads around the inside of the motor-vehicle roof, along the roof edge, and is provided with nozzles which are directed downwards and blow cold or warm air in a fan-shaped manner from above downwards directly onto the motor-vehicle windscreen, the side windows and onto the rear window. This pipe, of which there is at least one, is connected to a fan and to an air filter. The guidance of a ventilation pipe around the inside of the motor-vehicle roof is more favourable in terms of production than, for example, laying ventilation pipes through the motor-vehicle doors, which has the effect that air flows downwards from the top edges of the motor-vehicle doors. The current art in this motor-vehicle ventilation sector has, according to Offenlegungsschrift 2426946, advanced to the stage where air flows between the vehicle roof and the roof lining without the action of a fan.
