Title: Flexible perforated foil for dry shaver - has lattice pattern to provide shearing edges at most effective angle
Inventor: BRAUN ARTUR
IPC: B26B19/38
Filed: 1973-10-15
Abstract: The flexible perforated foil is formed into an arc so that it just touches the tips of the rotating blades of the shaver head. Longitudinal members run in the direction of rotation of the blade rotor whilst transverse members are set at an angle so that parallelograms are formed. A hair is pushed to a corner by the action of the blade and then cut off close to the skin surface. The lattice pattern is so formed that no intersection between two cross members and the longitudinal members occurs which produces a high degree of flexibility in the perforated foil to ensure that it is always pressed close to the rotating blades.

Title: Rotary vane pump with ring shaped rotor - has vanes projecting either side of offset rotor and engaging on central stator
Inventor: BERTRAMS JOSEF
IPC: F04C2/348
Filed: 1973-12-18
Abstract: The vane pump operates with a high degree of efficiency. One offset ring shaped rotor carries the vanes whose inner ends rest against a central stator which rotates with them. One ring holds the vanes in position and is pretensioned against their outside edges. The complete rotor leans against a pressure bearing and the pressure medium can be supplied and removed through the support bolt. The pre-tension holds the vanes against the stator with the stator passing on the load received to a roller bearing. The outer ring rotates with the vanes. Only low speed rubbing of the vanes against the central stator and the outer ring takes place, due to changes in the angles of the vanes.
