Abstract: "DIALYZER AND METHOD OF DIALYSIS"  ABSTRACT OF THE DISCLOSURE An apparatus and method for blood dialysis.  The device includes a plurality of semipermeable tubules for transporting blood therethrough. Distribution means are positioned adjacent the exterior of the tubules for admitting a dialysis solution which is passed along the outside of the tub-ules.  The tubules are preferably arranged in a configuration such that the packing density of the tubules is between about 20% and about 50%, and pref-erably between about 25% and about 35%.  This packing density insures ade-quate distribution of the dialysate solution as it is passed along the length of the tubules.  The tubules may be wrapped and similarly curved; in a preferred embodiment they are spirally orientated.  The configuration of the tubules allows for the movement of the tubules in a predetermined manner such that tubule masking is substantially prevented.

Abstract: BUBBLE TRANSLATION SWITCH USING MAGNETIC CHARGED WALL        Abstract of the Disclosure A switch for transferring magnetic bubble domains from one propagation path to another using a magnetic charged wall is described.          The magnetic charged wall bridges the two propagation paths and causes the domain to strip out along the charged wall.  By pulsing an overlying conductor, the charged wall and the associated strip domain will shrink away from one side of the conductor in order to translate the domain to the other side.  In contrast with previous transfer gates using current carrying conductors where the magnetic field produced by current through the conductors served as the major bubble translational force, the present switch utilizes a magnetic charged wall as the driving sources, the current through the conductor being used only for modification of the charged wall.  Therefore, the switching margins are maximized to be substantially the same as the bubble propagation margins and the switch-ing currents required are reduced from those in previously used transfer gates.  The present switch is particularly useful as a transfer gate in a major/minor loop memory which is fabricated using ion implanted propagation patterns. Various propagation element geometries can be used to provide the bridging charged wall.

Abstract: ABSTRACT OF THE DISCLOSURE:    An animal feed-stuff is prepared by mixing a residue obtained after extractive treatment of plant material, with inactivated brewers' yeast and other additives.  According to the invention, the cells of brewers' yeast are ruptured by hydrolysis and mixed in a wet state with the residue obtained after extractive treatment of plant material, with a nutritional supplement, and with a siloing preservative.  The invention is particularly suited to the treatment of brewer's draff since the yeast can be mixed therewith in a brewery.  The enriched draff-based porducts thus obtained are suitable for direct feeding to animals, and particularly because of the presence of the yeast they find high acceptability together with a good nutritional balance.

Abstract: ABSTRACT OF THE DISCLOSURE:           A pair of molded plastic components are juxtaposed face to face to form a body, U-shaped in longitudinal cross section on a plane perpendicular to the juxtaposed faces and include flanges on the sides thereof.  The external shape of the as-sembled body fits into a U-shaped space defined by the end of a wiper arm of the "shepherd's crook" kind.  The juxtaposed faces each have formed therein a transverse semi-cylindrical recess. When the sections are arranged face to face the recesses form a transverse bore to contain a grooved pin extending transversely from the side of a wiper blade harness.  An internal circum-ferential projection in the recesses engages the groove in the pin; the flanges engage the side edges of the arm.  A pair of resilient detents projecting outwardly from the web portion of the U-shaped body engage the web of the shepherd's crook arm.

The channel further includes a memory allocation unit (MAP) which can be loaded by transfer of memory allocation data via substantially the same common path as the I/O data transfer.  Appropriate control logic is also included to control the data and address transfers and the MAP load and dump operations so that blocks of data words can be transferred sequentially and directly to or from the memory.

Abstract: Abstract of the Disclosure A method of platinizing and heat treating tantalum metal is described.  The platinizing of tantalum is accomplished by placing a piece of conductive corrosion resistant metal and a tantalum workpiece as electrodes in a platinizing solution. The electrodes are connected to a source of DC power supply and when the current is passed, platinum black is deposited on the tantalum work-piece.  The platinized tantalum workpiece is then placed in a furnace maintained at a temperature of about 1050 to 1150°C for a time sufficient to diffuse the coated platinum into the surface of the tantalum core.
