Abstract: Abstract of the Disclosure Sub-micron carbon-containing titanium diboride powder and other hard, refractory metal boride powders, such as zirconium diboride and hafnium diboride powders, are prepared by vapor phase reaction of the corresponding metal halide, e.g., titanium halide, vaporous carbon source, and boron source reactants in the presence of hydrogen in a reaction zone and in the substantial absence of oxygen, either combined or elemental. In a preferred embodiment, the metal halide, e.g., titanium tetrachloride, carbon source, e.g., halogenated hydrocarbon, and boron source, e.g., boron trichloride, reactants are mixed with a hot stream of oxygen produced by heating hydrogen in a plasma heater. The reaction zone is maintained at metal boride forming temperatures and submicron solid, carbon-containing metal boride powder is removed promptly from the reactor and permitted to cool. The preponderant number metal boride particles comprising the preponderant number of metal boride particles comprising the powder product have a particle size in the range of between 0.05 and 0.7 microns. The metal boride powder product contains a minor amount of carbon, e.g., from above 0.1 to about 5 percent by weight total carbon, probably as submicron refractory metal carbide. Alternatively, submicron metal carbide powders, e.g., titanium, zirconium, hafnium or boron carbide powders, or finely-divided carbon can be blended physically with submicron metal boride powder prepared as described above but in the absence of the carbon source reactant to provide metal borides containing a minor concentration of carbon in the amounts previously indicated. Titanium diboride powder compositions containing minor amounts of carbon can be hot pressed, or cold pressed and sintered to densities of at least 95 percent of theoretical.

Abstract: ABSTRACT OF THE DISCLOSUSRE Automatic pre-collation document copying in which the documents are loaded upon, and automatically recirculated by, an elongate windable document holding web.  A spaced pair of oppositely wound scrolls of the web wind up documents loaded onto the web, where these documents are retained between the turns of the web on both of the scrolls during the copying operation. the web has a minor intermediate unwound segment extending between the two web scrolls where the documents are intermittently exposed for copying by appropriate optical systems for projecting the document images onto a xerographic drum or belt or other imaging surface.  A drive is provided for recirculatingly winding and unwinding the web between one web scroll and the other so as to recirculatingly expose, in sequence, the individual documents on the web as they appear on the unwound intermediate web segment.  The documents are thereby exposed in the pre-collated order in which they are loaded onto the web, or/and the reverse to produce correspondingly pre-collated copy sets.

Abstract: Abstract A method and apparatus is described for generating a data stream incorporating a self-clocking Manchester type code.  The data, originally stored in a shift register, is shifted out of the register in bi-level form with a first voltage level representing one binary value and a second voltage level representing a second binary value.  The output voltage levels from the shift register are applied simultaneously to two AND gates with an invertor interposed between the shift register and one of the AND gates.  Two clock pulse trains are utilized, one having a clock rate twice the clock rate of the other.  The clock pulses are respectively applied to the AND gates, the outputs of which are OR'ed and applied to a flip-flop.  The output pulses from the OR-gate clocks the flip-flop which toggles to provide a suitably encoded self-clocking data stream at the true and the not true outputs thereof.  The output from the flip-flop is applied to a line driver for driving a transmission cable that may be of the twin co-axial type.

Abstract: WEB SPLICING APPARATUS                 Abstract of the Disclosure A splicer for use with machines which receive and handle a web of paper or other suitable material supplied in a continuous length.  The paper is supplied from a pair of rolls and when one roll is exhausted, the other one is sub-stituted.  A movable splicer assembly is disposed adjacent a paper supply roll and which includes an idler roll, a paper stop device, a severing device and a splice sealing roll.          When the assembly is disposed adjacent the nearly exhausted paper roll, the stop device is actuated to hold the outgoing web from moving, regardless of the existence of adequacy of a roll brake.  When the assembly is disposed adjacent the spent roll, the stop device positively holds the paper for lead-edge cutting and trimming during set-up and to keep the paper in place until the splice is made.  The splice sealing roll has provisions to guide a cutting tool for said lead-edge forming of the fresh web, and also for optimally locating the lead edge.  An idler roll is disposed at the discharge end of the splicing area, with the idler roll cooperating with a tensioned dancer roll to maintain proper tension on the paper web at all times.  The idler roll is convertible to a capstan drive roll at the time of the splice to thereby increase the paper tension upstream and assist in acceleration of the web from the fresh roll up to normal speed.

Abstract: ABSTRACT OF THE DISCLOSURE   A shock absorbing ski pole is provided having a shock absorbing hand grip assembly cooperatively related and secured to a ski pole having a hollow shaft, and being mounted for up and down motion on the upper end of the ski pole.  To cushion shocks imparted to the ski pole, resilient means, e.g., a pneumatic cylinder and piston assembly, is mounted in the upper end of the ski pole and is operatively connected between the hand grip and the shaft.  In addition, means, e.g., a compression spring, is mounted in the upper end of the shaft to urge the hand grip to an upper position and also to cushion impacts on the ski pole.  An elongate fric-tion and positioning sleeve is positioned securely within the hand grip and frictionally engages the outer surface of the upper end of the shaft to provide a frictional drag force and to provide firm engagement between the hand grip and the shaft.  The components are so arranged that the length of the pole can be conveniently adjusted by disassembling the shock absorbing components, cutting the upper end of the shaft to a desired length, and reassembling the shock absorbing components in the upper end of the shaft, with the components being held in place by means of a pin engaging a pair of holes in the shaft at a second lower location.  This ski pole effectively absorbs shock impacts transmitted through the pole, provides a proper and secure "feel" of firmness and control for the skier, and yet provides ready adjustment of length on the ski pole.
