Abstract: ABSTRACT OF THE DISCLOSURE     A prosthesis for the surgical replacement of a dysfunctional knee joint is disclosed.  The prosthesis includes a tibial platform, one or two tibial bearing inserts, and a femoral component.     In a unicompartmental embodiment of the invention, the tibial platform includes a spike for securing the tibial platform to the tibia.  The tibial platform, in the unicompartmental embodiment, includes a track, which may be curved, and which is slidably engaged in dovetail fashion by a tibial bearing insert, typically of high molecular weight polyethylene.  The superior surface of the tibial bearing insert is concave spherical, designed to slidably engage the inferior surface of the femoral component.  The inferior surface of the femoral component is generally convex spherical, with radius of curvature slightly smaller than the radius of curvature of the tibial bearing insert.  In some embodiments the inferior surface of the femoral component may have two or more differing radii of curvature at different points on such surface.  Typically the tibial platform and the femoral component are constructed of cobalt-chromium alloy.     In a bicompartmental or tricompartmental embodiment of the invention, the tibial platform includes two tracks, each of which may be curved, and each of which slidably engages in dovetail fashion a tibial bearing insert.  The two tibial bearing inserts each engage, via their superior concave spherical surfaces, mating inferior convex sur-faces of the femoral component.  The two curved tracks are in general not concentric; rather, the center of each falls on a line normal to the plane of such curved track and passing through the center of curvature of the concave spherical surface of the tibial bearing insert of the other curved track.

Abstract: ABSTRACT A method of forming soluble collagen fibers from raw ani-mal hides is disclosed. Raw animal hides are treated with an aqueous solution of an alkali metal hydroxide and a dehydrating agent to remove the hair and fat therefrom to yield a substantially fat-free corium. The interfibular bonds of the collagen in the corium are stabilized with an aqueous solution of an alkali sulfate. The corium is neutralized and dis-solved in an aqueous acid solution to yield a collagen solution. The pH of the aqueous collagen solution is adjusted to the isoelectric point of the collagen to precipitate the collagen fibers from the solution. The collagen fibers are dried. The collagen fibers so produced are useful in edible food, may be redissolved and further processed for a plurality of uses.

Abstract: Abstract of the Disclosure An ac plasma panel is provided with self-shift capability.  Alternate columns of discharge sites, of the panel, referred to as "display" columns, hold the display information.  The latter is shifted to adjacent "transfer" columns by concurrently applying an excitation pulse to the sites in the display columns and a priming pulse to the sites in the transfer columns.  The excitation pulse creates a gas discharge at those display sites which are in the ON state.  The excitation and priming pulses, in combination, cause charge from the charge cloud created by each ON-display-site discharge to be transported to the adjacent transfer site.  The transported charge represents incipient wall charge for the transfer site and the latter switches to the ON state.  An erase  pulse is then applied  to the display sites.  Other pulses are utilized to preclude undesired inter-site interaction.

Abstract: METHOD OF PROTECTING NITRILOTRIACETATE SALTS    ABSTRACT           The trialkali metal salts of nitrilotriacetate are well known detergent builders.  However, when hypo-chlorite bleach is added to the wash water it can oxidize the soluble uncomplexed nitrilotriacetate with the resultant loss of the beneficial effects of the use of such salts as a builder.  Now, a method has been developed of protecting the desirable builder properties of the trialkali metal nitrilotriacetate in an aqueous solution containing active chlorine which comprises adding to the nitrilotriacetate a sufficient amount of trialkali metal imidodisulfate to protect at least some of the nitrilotriacetate from damage by the chlorine.

Abstract: ABSTRACT Improved shielding members and electric cable constructions which utilize these shielding members are described.  Various configurations of the shielding members can be used to enclose a single cable circuit consisting of one or more conductors in two concentric metallic shielding layers fabricated from a single shielding member which provides excellent electrical isolation for the cable circuit.  Generally the shielding members comprise an elongated ribbon of insulating material and a pair of elongated foil strips arranged in a parallel relationship with the ribbon. The foil strips are bonded to opposite sides of the ribbon and each have an elongated edge generally in alignment with opposite elongated edges of the ribbon. The selective use of layers of heat sensitive sealing material for the shielding layers protects the cable circuits from moisture.

Abstract: ABSTRACT     A self-cycling reciprocating piston motor has the piston biased in return stroke direction and driven in power stroke by air pressure introduced between the head of the piston and a closure across the end of the working chamber cylinder.  A valve which closes an exhaust port leading from the working chamber, is opened at the end of the power stroke by working chamber air pressure and the air pressure is evacuated from the working chamber.  The valve is returned to closing relation to the port by the returning piston, thereby resetting the motor for another cycle of operation.  Working chamber air pressure leads through an air passage from an escape port opening through the cylinder and adapted to be exposed to the working chamber at sub-stantially the end of the power stroke of the piston.  The piston has a peripheral groove within which is mounted a pair of O-rings for maintaining a sealed engagement with the cylinder, the O-rings occupying less than the full width of the groove, so that as the piston reaches the escape port, the O-ring nearest the piston rod and of the piston passes the escape port while the o-ring nearest the head end of the piston maintains a sealed relationship about the piston and escape of air pressure is prevented until the first O-ring has passed the escape port, whereafter the second O-ring follows past the escape port and pressure air can escape from the head end of the piston through the groove and out through the escape port, whereby stalling of the piston is prevented.

Abstract: A B S T R A C T            A wire magazine for winding wire for use in a winding machine for the winding of elongate, preferably endless annular members or cores.            A wire magazine for winding wire for use in a winding machine for the winding of elongate members or cores, preferably endless cores, comprises two annular halves (9, 10) which are designed with thin walls of a substan-tially semi-circular cross-sectional form to provide a substantially closed storage space. The halves are sepa-rated by a wire filling slit (11) on the external side of the magazine and a bottom slit (12) on the innerside of the magazine facing its axis of revolution, said bottom slit (12) being defined by edge portions of the two halves (9, 10) having walls, the surfaces of which deviate from a planar parallel relationship to the sym-metry plane of the wire magazine normal to the axis of revolution. With this design of the wire magazine, an optimum residual hole condition in the winding of toro-idal cores is obtained and simultaneously an  efficient holding of winding wire within the magazine after cutting of the wire is secured in addition to an improved securi-ty against slipping of the wire drawn out through the bottom slit (12) and an optimum possibility for correct control of the friction between the wire and the walls of the bottom slit (12) and, thereby, of the wire ten-sion. The walls of the bottom slit may, for example, have a longitudinal wave form.            (Fig. 2)
