Abstract: ABSTRACT OF THE DISCLOSURE Metal prosthetic devices having stems implantable in bone are known, the stem of each such device extending from a collar surface designed to bear against the cut surface of the bone.  In this invention, an interpositioning collar made from a material having a low modulus of elasticity is provided which can be fitted onto the stem and be partially implanted therewith to improve the joint between the cut bone surface and the collar sur-face of the prosthetic device, as well as the joint between the im-planted stem and the adjacent bone portions.  The interpositioning collar consists of a flat elongated, lengthwise tapered collar element which may be either O-shaped or U-shaped and a flange which is U-shaped and extends perpendicularly from the lower face of the collar element.  In use, the collar element and flange em-brace the implanted stem of the prosthetic device, the collar ele-ment lying immediately below the collar of the prosthetic device and flat on the cut surface of the bone, with the flange extend ing into the bone alongside a topmost portion of the stem.

Abstract: RUN LENGTH ENCODING AND DECODING METHODS AND MEANS                     ABSTRACT OF THE DISCLOSURE Black and white run length encoding means first convert a binary video input signal having a raster scan format into binary black and white run length message codes which are preselected so that the initial or lead bit of each of those codes is at a given logic level. Ternary encoding means convert the binary message codes into a series of ternary black and white run length message codes which have distinctive amplitude transitions at any intra-scan line code boundaries, and a frequency modulator then frequency modulates a carrier signal in accordance with the ternary codes to provide a passband signal suitable for transmission via a limited bandwidth communications channel. To recover the video signal from the passband signal, the process is reversed.

Abstract: ONE-HANDED KEYBOARD AND ITS CONTROL MEANS              Abstract A keyboard which has ten keys controlled by the four fingers and four keys controlled by the thumb of the same hand.  On it, the operator forms chords somewhat as a pianist forms chords on a piano.  It allows the user to type at normal speed using only one hand and offers the possibility of typing at a faster rate than the conventional two-handed keyboard.    The operator presses several keys at once, as when playing a chord on a piano.  Each finger or thumb can press one key, or overlap two or four adjacent keys to press the two or four keys.  There are 27 such finger positions on the 10 finger keys and 7 thumb positions on the four thumb keys.    The thumb position on the thumb keys select the alphabet/case, output order of characters in the chord, a space character preceding the chord, and capitalizing of the first outputted character of a chord.  The finger positions on the finger keys select the characters in the alphabet/case selected by the thumb position.    The disclosed system describes a mechanical design of the keys, and control circuits that interprets the chords and emits signals representing the strings of characters implied by the chords.

Abstract: GAS MONITORING METHOD AND APPARATUS THEREFOR                   James O. Henrie ABSTRACT      A method and apparatus for monitoring the concentration of a component of a gas stream.  The gas stream to be monitored is heated to a desired temperature and passed through an insulated gas passageway of a conduit member.  The heated gas passes sequentially through a perforate metal shield and a body of a particulate catalyst.  The temperature of the heated gas entering and leaving the conduit member is monitored and any increase in temperature is correlatable with the component concentration in the gas stream.  The method and apparatus are particularly suitable for monitoring the concentration of hydrogen or oxygen in a gas stream.

In one specific instance, a plate having the configuration of a rectangle is utilized.  This plate may have a size such that only one end portion of the plate will fit in a working chamber at a time.  After a plurality of airfoils have been formed in one end portion of the plate, the plate is withdrawn from the working chamber and the opposite end portion of the plate inserted into the working chamber.  In another specific instance, the workpiece included a support frame in which a plurality of partially formed airfoils are mounted.  A plurality of pairs of electrodes are utilized to electrolytically remove material from opposite sides of the partially formed airfoils.  During the electrolytic removal of material from opposite sides of the workpiece to form the airfoils, electrolyte flows axially along each of the side surfaces of the airfoil from a tip end portion toward a root end portion of the airfoil.

Abstract: ABSTRACT OF THE DISCLOSURE A corona discharge monitor system for a dynamo-electric machine, particularly for large salient pole generators, has an antenna mounted on a rotor pole.  The antenna sweeps over the stator slots and picks up radio frequency signals produced by corona activity occurring in the structure of the stator bars.  A rotary coupler, having a rotating portion fixed to the shaft of the machine and a fixed portion adjacent to the rotating portion, couples the signal to a signal conditioner.  A trigger signal synchronized with the rotor rotation and with a known reference to antenna position and derived from the power system line frequency, is used as one input to a storage device such as a variable persistance oscilloscope.  A first output of the signal conditioner represents the peak amplitude of the corona discharge and a second output represents the number of corona occurrences and these are applied to the storage device.  A display is provided with reference to the trigger signal in such a way as to associate the first or second output with each slot, or if not a particular slot, at least within a limited number of slots.

Abstract: ABSTRACT OF THE DISCLOSURE              Pieces of flat glass are cut to desired size without the necessity of grinding to size and polishing.  Edges of the piece are cut in accordance with a procedure involving the use of a large-diameter scoring wheel at a greater-than-usual applied pressure, to produce a subsurface discontinuity, e.g., a subsurface score or a subsurface crack, followed by the application of a bending moment about the subsurface discontinuity to propagate a fracture in the piece of glass.  Trims may be removed from the piece in accordance with a procedure involving the creation of a subsurface discontinuity along an intended path of cut, followed by the application of surface heat along the discontinuity to increase tensile stresses within the piece along the intended path of cut.  A bending moment is then applied about the intended path of cut to propagate a fracture in the piece of glass. Light seaming of the top and bottom portions of the edges completes the pre-paration of those edges.

Abstract: ABSTRACT OF THE DISCLOSURE           An electrolytic cell employing a hydraulically impermeable membrane having a spacing means interposed between the anode and the membrane, is operated by providing a positive pressure differential between the cathode compartment and the anode compartment.  The pressure differential is sufficient to maintain contact between the spacer and the membrane to provide uniform spacing between the anode and the membrane.  In addition, this process provides sufficient spacing between the membrane and the cathode to provide efficient release of any gas formed and to prevent gas blinding at the cathode.  Employing the positive pressure differential enables the cell to be operated at reduced energy costs when producing, for example, concentrated solutions of sodium hydroxide by careful control of the spacing between the membrane and the electrodes.

Abstract: ABSTRACT OF THE DISCLOSURE:     Milk is sterilized by a cold treatment with hydrogen peroxide as sterilizing agent and the residual, hydrogen peroxide is subsequently converted to water and oxygen by having the milk flowing through fibers in which a catalase enzyme is occluded.  The catalase-occluding fibers can also loosely be added to the milk.  This treatment avoids the administration of heat and ensures that no residual hydrogen peroxide is left in milk.  The flavor and taste qualities of milk are wholly unaffected by this treatment.
