Abstract: HYDRAULICALLY ACTUATED CARDIAC PROSTHESIS            ABSTRACT A cardiac prosthesis having an hydraulically actuated compressible blood pump (RV). An actuation chamber (116) adjacent the blood pump (RV) receives pulses of hydraulic actuation fluid from an actuator pump (120) through a fluid inlet path (126) to compress the blood pump (RV) during systole and eject blood therefrom. Between pulses the actuation fluid is permitted to drain from the actuation chamber (116) through an outlet path (132) into a reservoir (12). Discharge of fluid through the outlet path (132) is controlled by a dump valve (130) which is adapted to close or open the outlet path (132) primarily in response to forces which vary as a function of the flow of actuation fluid through the fluid inlet path (126).

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for the volume reduction of radio-active  liquid waste  solutions such as evaporator waste bottoms containing boric acid or sodium sulfate and trace quantities of radioactivity through a vacuum evaporative cooling crystallization process or an evaporative crystal-lization process.  A crystallization unit has an internal baffle which separates the center portion of the unit into a quiescent zone where crystallization can be effected and an inner chamber into which the liquid waste is tangen-tially  introduced.   The  waste  is  circulated  from  the bottom of the crystallization unit through a heat ex-changer which adjusts the temperature of the liquid waste and  maintains  the  temperature  within  a  predetermined range.  The vacuum draws off a portion of the solvent in the  solution.  Upon the  crystallization  of  the  liguid waste solution to a degree which renders a solid-liquid slurry,  the  slurry is  removed  from  the  apparatus  for further treatment.

Abstract: ABSTRACT An axial air gap magnetic drive motor having a diaphragm to seal the drive motor from the pump is disclosed.  The drive motor drives a posi-tive displacement pmup through a magnetic coupling on both sides of the diaphragm.  The gerotor pump includes an annular backing plate member. an inlet member and a three piece pump which is rotated by the drive motor through the magnetic coupling.  The three piece pump includes a male rotor gear, an annular female gear cooperatively engaging the male rotor gear and an outer annular member disposed around the annular female gear.  The inside diameter of the outer annular member is eccentric a predetermined radial distance from the axial center line.  The outer annular member, the inlet member and the backing plate member are pinned to one another to prevent relative movement therebetween.  A pair of biasing members are mounted between the opposite end of the housing and the inlet member to urge the inlet member towards the three piece pump and the backing plate member to reduce axial clearance therebetween.

Abstract: PALATABILITY OF DOG FOOD INCREASED BY  SELECTIVE TREATMENT OF MEAT MEAL                           ABSTRACT            The object of the present invention is to provide an improved process for preparing a dog food having improved acceptability.  It is also an object to provide a product improved by that process.      It has been difficult to obtain the advantages of high corn contents in dog foods due to a negative effect corn has upon palatability.  According to the present invention,  at least a major portion of the corn is withheld from processing while the other components of the dog food are subjected to heating in the presence of moisture prior to extruder expan-sion.  It has been surprisingly found that minimiz-ing the treatment of the corn and treating at least some  of the  farinaceous  and proteinaceous  ingre-dients by heat and moisture improves the overall palatability of the dog food.

Abstract: Abstract of the Disclosure Gamma correction in an imaging system which provides photographic reproductions of images represented by video signals is achieved by controlling the duration of exposure of a constant intensity scanning beam.  A moving threshold signal is swept at a varying rate corresponding to a gamma correction curve between opposite limits over a given total exposure interval, as the image is repeatedly presented.  The instantaneous amplitude of the video signal is compared to threshold signal and the results of the comparison used to control whether the beam is on or off for a given picture area.  The gamma correction curves are advantageously presented as numerical sequences defining interlinked incremental segments of different slope.

Abstract: SHOWER HEAD     ABSTRACT OF THE DISCLOSURE          A shower head is disclosed of the type having a pivotally mounted spray head.  The shower head comprises a first member adapted for attachment to a water supply pipe and a spray head pivotally mounted to the first member.  The first member includes a concave, socket-defining surface with a water supply aperture therein.  The spray head has an inner spray body, through which the water flows, and an outer retaining sleeve, which secures the spray body to the first member.  To prevent leakage between the spray body and the sleeve, an annular seal is carried by the spray body and slidably engages the concave surface of the first member along a line which encloses the water supply aperture at all pivot positions of the spray head.  In the preferred embodiment, the inlet end of the spray body defines a flow-limiting vortex chamber, into which water is directed in a swirling action.  As presently understood, the swirling action creates a centrifugal action away from the center outlet of the vortex chamber, which limits the volume of water flowing through the spray body.
