Abstract: The invention relates to a rotary vein pump, whose rotor (4) consists of a rotor body (10) arranged on a drive shaft (9) and working slides (11), which are guided radially movably in slots provided in the rotor body (10). A reduction of the force pressing the working slides against the inner wall of the pump housing, and consequently a diminution of the frictional losses and of the wear on the working slides and on the pump housing is achieved by virtue of the fact that the working slides (11) are provided with a piston-like extension (strip 12), the slots (13) are extended, at least over a length corresponding to the stroke of the working slides (11), to form a piston chamber (14) corresponding to the piston-like extension (strip 12) of the working slides (11) and a compressive force opposing the centrifugal force is applied to the working slides (11). <IMAGE>

Abstract: In such an angular-position measuring system for measuring the angular position of two objects that can be rotated relative to one another, a dividing plate (TT1), which is connected to one object, has on its surface (O1) an angle scale (WT1) whose involute-shaped graduation marks (TS1) proceed from a basic circle (GK1) centred at the midpoint (M1) of the dividing plate (TT1). This involute-shaped angle scale (WT1) is scanned in two diametrically mutually opposing angle scale ranges (WB1a, WB1b) by a scanning device connected to the other object. The scanning device has a semiconductor laser, four deflecting mirrors (US1a-US1d), two linear scales (LT1a, LT1b), and a photoelement. The measured values for the relative angular position of the two objects are determined from the periodic scanning signal delivered by the photoelement. Since the graduation marks (TS1) of the involute-shaped angle scale (WT1) do not fan out, measurement inaccuracies are avoided. <IMAGE>

Abstract: A rotatable shaft element (311) has a disc part secured thereto. An electromagnet (314) is located relative to the part (312) so that an armature (315) of the electromagnet (314) which engages the circumference of the part (312) is also maintained at a minimum distance from the electromagnet (314) even when the latter is de-­energised, but can enter a recess (313) to arrest rotation in one direction. Rotation in the opposite direction causes the armature (315) to return to the periphery of the part (312). Energisation of the electromagnet (314) allows the recess (313) to pass the armature (315) in either direction. The electromagnet (314) is thereby required to act on the armature (315) only when the latter is close to the electromagnet, with consequent reduction of input power required.
