Patent DE-2224015-A1 (DE)
Title: Vulcanising pneumatic tyre - with beading widely spaced apart at optimum position
Inventor: PAKUR HENRYK
IPC: B60C3/04
Filed: 1972-05-17
Abstract: A method of calculating the transverse contour of a pneumatic tyre, esp. with radial reinforcement, which is to be adopted while the tyre is in the vulcanising mould, i.e. with the beadings at a considerably extended distance apart as compared with the final designed spacing when mounted on the wheel, is as follows: the position adopted is such that the side walls run parallel to the axis of the tyre at the transition to the tread region, and that when the tyre is narrowed to its operating shape, the sides walls also satisfy the same condition, i.e. the optimum position selected for vulcanising the tyre is that in which there is a smooth transition from its walls to the fixed cylindrical tread region without any kink or sudden change of curvature. The other optimum position is the one adopted with narrow beading spacing when the tyre is mounted on the wheel.

Title: Quick-fixing button - needle like extension and double hook for anchorage in cloth
Inventor: OLOVSON GUDMAR
IPC: A44B1/18
Filed: 1973-06-20
Abstract: Knob body and needle are connected by an expandable neck. The needle part is pushed through the cloth, while the double hooks are fitted below the neck in such a way that they stay flat against the neck.

Title: Irregular pattern of surface scratches on extruded roofing tile - is produced by brushing followed by light sponging
Inventor: GERHAHER MAX DIPL ING
IPC: B28B11/08
Filed: 1974-09-03
Abstract: The known method of producing the required scratched surface finish on the tiles is to stretch a wire across the mouth through which the tiles are extruded so as to remove uncontrolled amounts from their upper surfaces. By the invention, the wire is replaced by a cylindrical brush (7) which rotates against the surface of the newly-extruded length of tiles. There follows a dampened cylinder of sponge (8) to stick back any particles the brush has loosened; it does this without spoiling the general effect of the brushing. The appearance of the finished surface can be varied by changing the brush and/or sponge for another of a different texture, and/or by reversing the rotation of one or both of them. The sponge (8) can also be rotated and a watering device (9) can be positioned over the sponge.

Title: High pressure water pump - has high pressure oil pump feeding large diameter oil to water pressure convertor
Inventor: ECKEY FRIEDHELM
IPC: F04B9/10
Filed: 1974-11-29
Abstract: The pump has an electric motor (1) driving a reciprocating piston oil pump (2). A manually adjustable pressure regulator (10) and an oil cooler (3) are arranged between the motor and the pump, and all these components are contained within the oil reservoir (12) which thus forms a support frame for the pump. A second and separate assembly contains the pressure convertor (4) with the reversing valve (5) fed from the oil pump. This construction enables the pressure convertor to have a large diameter plunger with a low piston speed which reduces friction and wear on the parts moving in a non-lubricating fluid. The pressure regulator keeps the pressure constant over a range of varying volume flow. The oil side can operate at comparatively low presures.
