Abstract: ABSTRACT             "Veno-Ject" is a tenderizing process in which a calculated amount of wine, relative to the size of the dead animal ie. (rabbit, sheep, cattle, swine, deer, moose, etc.) is injected into the vascular sys-tem under pressure from a pump syringe via a major artery ie. (Thorac-ic aorta, abdominal aorta, common carotid, external ilieac or fem-oral arteries, etc.) and the blood is flushed from the venous system via a major vein ie. (internal jugular, superior vena-cava, inferior vena-cava, or femoral veins, etc.)  The process is completed once the arterial, capilliary, inter-cellular spaces and venous systems are saturated with wine and the animal is eviscerated and the carcass is allowed to hang at approximately 38°F. for a required period until the wine has reacted on the tissue resulting in a thorough tenderizing of the meat for eatable purposes.

Abstract: ABSTRACT OF THE DISCLOSURE           An automatic cutoff and tester apparatus for a gas supply utilizes a diaphragm powered main valve between a gas inlet and a gas outlet.  In the event of an earthquake, etc., a weight is dislodged from a magnet to control via a lever assembly a sensor valve to release gas pressure from a chamber containing the diaphragm thereby to close the main valve.  Manual resetting returns the weight to a position in which it can be attracted to the magnet and opens a resetting valve to permit a small supply of gas to the chamber for testing purposes.  If this gas does not leak away pressure in the chamber rises to control the diaphragm to open the main valve.

Abstract: ADDITIVE TRANSFER DEVICE            Abstract of the Disclosure An additive transfer device for storing and trans-ferring of a medicament to a solution container such as an I.V. bag having an exposed port.  The transfer device is accommodated in the neck of an additive container having a pierceable sealing element.  A holder member for a doubled pointed end piercing member engages a cap covering the tubu-lar neck and affords a movement of the piercing member to-ward the sealing element to pierce it.  Guide means extend from the holder member and fit over the tubular port of the I.V. bag.  When the opposing pointed end of the piercing element is pierced through the I.V. port, communication can be made between the additive container and the I.V. bag.        In a preferred manner, the contents of the additive container are expelled by collapsing the walls which force the medica-ment into the I.V. bag by means of the piercing element.

Abstract: ABSTRACT OF THE DISCLOSURE     A torque transmitting assembly for effecting rotation of a valve member such as a butterfly valve is hermetically sealed to the valve housing.  It includes a rotor member having a plurality of circumferentially spaced permanent magents of opposite polarity and  a driver magnet assembly having a like plurality of circum-ferentially spaced permanent magnets of opposite polarity facing the magnets mounted to the rotor.  The two sets of magnets are separated by a stainless steel separator which hermetically seals the rotor.          The driver magnet assembly is rotatable about the separator so that magnetic coupling forces effect a following rotation of the rotor and hence of the valve member.  A magnetic indicator may be used to identify the rotational position of the rotor.  The entire assembly is hermetically sealed and no packing is required.  The assembly is especially useful to control a valve in a hazardous environment wherein no leakage of the fluid being controlled by the valve member is permissible.

Abstract: ABSTRACT         Modern circular knitting machines are designed to provide the capability of knitting complex pile patterns through the use of electromechanical and mechanical systems which can be computer con-trolled so that systematic pile pattern variations from wale to wale, suitable for the use in manufacturing synthetic fur pieces, can be achieved.  No one has heretofore succeeded in producing a sliver knit pile fabric product comprised of seemingly seamed together animal pelts which fabric product has undergone contour shearing in good register prior to heat shrinking of pile fibers contained therein.  According to the present invention, there is provided process technology for making a synthetic fur piece from a sliver knit, high pile, differentially transversely knitted, longitudinally patterned, unstabilized starting fabric having a pile containing heat shrinkable fibers.  The process involves stabilizing the start-ing fabric, contour shearing same, and then further processing the resulting sheared fabric under conditions which result in heat shrinking of the heat shrinkable pile fibers therein.  The pre-ferred product is a synthetic fur piece comprised of seemingly seamed together animal pelts.  Various finishing operations typically and preferably are performable upon such a product to enhance fur-like properties and to simulate the appearance and qualities of specific desired animal furs, such as, for example, mink.

Abstract: ABSTRACT OF THE DISCLOSURE      A container is disclosed for storing a heat storage medium which changes between solid and fluid states to store and release heat, characterized in that the container includes flexible walls which are displaced to vary the volume of the heat container in accordance with changes of the volume of the heat storage medium when in the solid state. The container includes at least one biasing device which normally biases the resilient walls toward an inwardly contracted condition for storing a first volume of the heat storage medium in the fluid state. During initial removal of heat from the medium, the medium changes from its fluid to its solid state, and upon further removal of heat from the solid medium, the density of the solid medium increases, thereby resulting in a decrease in the volume of the solid medium with the container remaining in its initial contracted condition.  Upon addition of heat to the solid medium, the density of the solid medium decreases thereby resulting in an increase in volume of the solid medium and an attendant increase in volume of the container to its expanded condition.

Abstract: A METHOD FOR FORMING A LIQUID PHASE EPITAXIAL FILM ON A WAFER                             Abstract A method of forming an improved liquid phase epitaxial film on a wafer.  The resultant film has improved uniformity of magnetic properties, such as the collapse field (Ho), across the surface of the wafer as well as being substantially free of mesa defects on the surface.  The method includes the step of growing the liquid phase epitaxial film while the wafer is in the horizontal plane.  The wafer is removed from the melt while the wafer is tilted at an angle from the horizontal plane so that the melt may drain from the wafer. Then the wafer is positioned in a horizontal plane again and rotated to remove the remaining melt droplets from the edge of the wafer.  In a preferred embodiment, a plurality of wafers are positioned in a wafer holding means so that the wafers are arranged in a stacked manner having substantially the same space between adjacent wafers. Wafers may also be stacked in pairs that are back-to-back while carrying out this method.
