Title: Drive for rotating multi-cell unit - extracting material from solids by sprayed solvents, used esp. to extract oils from seeds
Inventor: PUST MANFRED
IPC: B01D11/02
Filed: 1979-12-18
Abstract: A unit continuously extracts required materials from solids by solvent sprayed from above into a series of radical cell sectors in a casing rotating about a central vertical axis. The enriched soln. is extracted from a tapered chamber at the unit base and can be recycled, while the solid residues are expelled after almost completing a circuit. On the casing exterior is a continuous ring of rollers rotated by a series of outwardly fitted drive cogs uniformly spaced round the casing and held in resilient contact with the ring. Each drive cog is mounted on an arm held by meshing gears and which can rock through e.g. 20-70 deg. about a fixed vertical shaft. Rotation of the cell unit applies a torque which keeps the drive cog in contact with the rollers. A chain drive may be used instead of the meshing gears, with a spring to ensure engagement with the rollers. Used e.g. in extn. of oil from seeds. Less dimensional accuracy is needed in drive components than with known devices. Defective drive units can be replaced without stopping the complete operation.

Patent DE-3006323-A1 (DE)
Title: Purified air feed esp. into automobile - heats air before filter to improve sorption and catalytic effects
Inventor: HOELTER HEINZ ING GRAD
IPC: B60H3/06
Filed: 1980-02-20
Abstract: A method of purifying air to be fed into a protected working zone or automobile cabin utilizes a filter consisting of a permeable support on/in which chemical absorption materials and/or catalysts are laid. The incoming air is entirely or partly heated before it reaches the filters. When the appts. is in use, the normal fresh air inlet ducts of an automobile are closed and the ventilator fan is converted for use as a pure circulating fan recycling the entire air content of the vehicle. In addn., a separate ventilator fan draws in air and expels it at above-atmospheric pressure into the circuit via the chemical absorption filter. A corresponding quantity of air escapes from the circuit to atmosphere. In particular for automobiles in traffic jams or smog conditions as a substitute for conventional ventilation. By heating the air before it reaches the chemical absorption filter, moisture in the air is prevented from precipitating. Precipitation of moisture has a very adverse effect upon the effect of chemical absorption agents and catalysts. Thus the efficiency of the plant is greatly improved.

Title: Detachable hinge for the sideboard of vehicles
Inventor: PALES ROMAN
IPC: E05D5/14
Filed: 1981-03-16
Abstract: Detachable hinges for the sideboard of vehicles are known. These have an upper part which is to be fastened, for example, to the sideboard and has a parallel pin (15), supported at one end, and have a lower part which is to be fastened, for example, to the vehicle frame and has a cheek with a cylindrical cutout receiving the parallel pin. Hinges of this type can be detached and reattached. However, when pivoting the sideboard out of the closed position into the open position, or vice versa, there is the risk of unintentionally detaching it and hence the risk of injury to the operator. In order virtually to eliminate this risk, the parallel pin (15) is made longer than the cheek and provided at its free end (16) with a locking projection (17) protruding radially beyond the periphery. The cheek is divided into two individual cheeks (4, 5) which each have an opening (8, 9) protruding radially beyond the periphery of the cutout, arranged mutually offset along the periphery and intended for the passage of the locking projection (17). Provided between the individual cheeks (4, 5) is a free space (10) connecting the two openings (8, 9). <IMAGE>
Patent DE-3110114-A1 (DE)
Title: Detachable hinge for the sideboard of vehicles
Inventor: PALES ROMAN
IPC: E05D7/10
Filed: 1981-03-16
Abstract: The invention relates to detachable hinges formed symmetrically to the longitudinal centre plane and intended for the sideboard of vehicles. The hinges have a housing-like lower part which is to be fastened to the vehicle frame and has two side cheeks with groove tracks which have a restriction at the introduction end and terminate in cylindrical bearings. The hinges furthermore have an upper part which is to be fastened to the sideboard and bears two bearing projections allocated to the groove tracks with the bearings. In the case of the above hinges, there is the problem that a sideboard of this type could unintentionally be detached when being pivoted out of the open into the closed position and vice versa and by falling down could injure the operator. This danger is virtually eliminated if the groove tracks of the side cheeks and/or the flattened portions of the bearing projections are provided with a directional change.
