Abstract: ABSTRACT OF THE DISCLOSURE         A rotary piston pump for the displacement of blood has a single-lobe trochoidal surface along the peripheral wall of a housing and an eccentrically displaced rotary piston having a pair of opposite edges confronting this surface.  The edges confronting the surface are rounded of circular arc curvature with a radius less than the equidistant between the theoretical epitrochoid of the orbits of these edges and the surface.  A gap seal is thus pro-vided which prevents damage to blood vessels when the pump is used for the circulation of blood, e.g. in an artificial heart.

Abstract: ABSTRACT In a vortex flow meter for measuring a varying flow rate of a fluid through a conduit, an oscillation compensating apparatus is constructed to remove undesirable externally derived oscillation noise which is applied to the flow meter.  An elongate vortex shedding member extends into the conduit through part of its wall.  The shedding member forms a shedding portion inside the conduit and a compensating portion outside the conduit.  The shedding portion carries a first oscillation sensor therewith and the compensating portion, a second oscillation sensor.  The first sensor is sensitive to an oscillation component caused in the shedding portion by a vortex train shed in the conduit, and an externally derived oscillation noise component.  The second sensor is sensitive to the noise component only.  All these sensed components are combined to cancel the oscillation noise so that only the oscillation component in the shed-ding portion is picked up.

Abstract: INVENTORS: PAUL FRIEDLI, THOMAS HINDERLING and GUNTRAM BEGLE          INVENTION: SET VALUE TRANSMITTER FOR A DRIVE REGULATION            APPARATUS                    ABSTRACT OF THE DISCLOSURE     With this set or reference value transmitter which is controlled by a set or reference value clock pulse generator or transmitter regulation of the running-up or acceleration of electric motors, such as asynchronous motors, can be kept under control also in the upper rotational speed ranges of the motor by  adapting  the  displacement  path-reference  value characteristic curve to the displacement path-actual value characteristic curve.  For this purpose the reference value transmitter comprises a correction member, by means of which the displacement path-regulation deviation is supervised in such a way that if the greatest displacement path-regulation deviation associated with the maximum power of the adjusting or positioning members is exceeded, the clock pulse frequency of the  reference value  clock pulse  transmitter is reduced proportionally to the excess.  The displacement path-reference values are supplied to the displacement path regulation circuit in correspondingly larger time intervals until the greatest displacement path-regulation deviation is fallen short of, whereupon the reference value transmitter continues to operate with the original clock pulse frequency.

Abstract: 26                  51,857 ABSTRACT OF THE DISCLOSURE A rotary, snap-action electrical switch suitable for immersion in the liquid dielectric of an electrical transformer.  The switch includes a multi-position operat-ing mechanism which  latches each switch position while preventing contact rebound,  absorbing all closing forces in  the  mechanism  itself.   A  switch position indicator follows the movable contact, and not the actuating handle. A three-position embodiment of the switch rotates one end of a pivotable contact on a stationary contact, removing contact bias means from the current path.  The remaining end is selectively engageable with either of two addition-al stationary contacts,  as well as having a non-contact open circuit position.  The pivotable contact is driven at a point intermediate its ends, to increase the torque arm and thus obtain the desired operating force with substan-tially reduced forces between the driving member and the contact carrier.
