Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for controlling the scanning path of a rotary transducer which is used in a signal reproducing system of the type having at least one rotary transducer which scans across a movable record medium to reproduce, during each pass of the trans-ducer, signals which are recorded in parallel record tracks, the apparatus being particularly useful when the record medium is moved either at a faster-than-normal or slower-than-normal speed so that the transducer scans plural record tracks during each pass thereof.  A control signal generator produces a periodic tracking control signal which is synchronized with the speed at which the record medium is moved, the periodic control signal having a plurality of periods during each pass of the transducer. An adjustable support is provided for the transducer, the adjust-able support being responsive to the tracking control signal to displace the transducer transversely of the scanning path thereof, such that the transducer scans successive segments of predetermined record tracks during each pass thereof.  In one embodiment wherein the transducer is used to scan adjacent record tracks which have been recorded with different azimuth angles, the adjustable support is controlled such that a segment of one record track is scanned, then the next adjacent record track is skipped and a segment of the next -following record track is scanned and so on.  Thus, only segments of those record tracks which are recorded with the same azimuth angle are scanned.  This apparatus is especially useful in a search mode of, for example, a recorded video tape.

Abstract: ABSTRACT OF THE DISCLOSURE             The instant invention relates to a method for preparing high activity supported nickel catalysts. The method comprises the deposition of nickel nitrate on a carrier, typically an inert inorganic refractory oxide, by techniques known in the art followed by careful heating to a temperature of between 100 to 270°C., avoiding any excursions into temp-eratures beyond the stated maxima, in a flowing nonreactive gas atomsphere for a time sufficient to convert substantially all of the nickel nitrate into nickel oxide. When using an H2 containing atmosphere the maximum temperature is 220°C. The supported nickel oxide resulting from the aboveprocedure is them reduced to a supported nickel metal catalyst in a re-ducing atmosphere at a temperature ranging from about 230°C. to 400°C. The instant invention also relates to a new class of supported nickel metal catalysts having a specific activity of at least twice the specific activities of prior art catalyst as determined for the hydrogenation of benzene. These catalysts comprise from 0.1 to 50 weight % nickel on a support, preferably 0.5 to 20 weight I nickel, most preferably about 17 weight % nickel on a support wherein the support is as defined above.

Abstract: ABSTRACT OF THE INVENTION    ICE SKATE SHARPENER     The invention comprises an improved ice skate grinding, sharpening and contouring machine, The machine includes novel means to accurately center an ice skate between the heel and sole struts in a movable holding fixture and means to select the best contour position on the blade as a function of intended skate usage. As an example, the best blade contour for a hockey forward requires a deeper grind below the forward strut than the contour for a hockey defenseman. The centering feature assures that the skate contour desired will be accurately ground onto the blade and pitched forward the desired amount. Means to adjust the blade position relative to the blade hoding fixture for pitching are disclosed in one embodiment. In an alternative embodiment means for pitching the entire fixture as desired are disclosed. Figure skates can be advantageously centered and pitched as desired with the invention for accommodating the particular requirements of the figure skater. New hockey skates with unconventional molded plastic struts such as the Canadian TUUR 2000 have entered commerce. Such skates are accommodated by a modified method of determining the blade center location that is equivalent to the center location of a hockey skate with conventional struts.

Abstract: UNDERSCORE ERASE                    Abstract of the Invention The electronic controls for a typewriter disclosed herein allow the operator to erase a character using automatic erase capability such as disclosed in U. S. Patent 3,780,846 and at the same time to remove any underscores associated with that character.  When an underscore command is entered the memory which stores the code representing the characters typed is caused to be altered in its content to indicate upon the reading of that code segment that the character has been underscored and that the character must be erased along with the underscore.  The apparatus accomplishes multiple erase cycles to remove the underscore and then the character.  In proportional space mode of operation it is possible that multiple underscore erase cycles will be necessary to remove an underscore which is wider than the underscore type font on the type element.

Abstract: IGNITION DWELL CIRCUIT FOR AN   INTERNAL COMBUSTION ENGINE               Abstract of the Disclosure Electronic signal processing circuitry for use in the ignition system of an internal combustion engine is disclosed herein.  A signal generator which receives crankshaft position pulses from a sensor and produces periodic output pulses which have durations equal to a constant percentage of the period of the input sensor pulses is disclosed.  The generator includes a crankshaft position sensor feeding a bistable flip flop which controls a dual slope integrator circuit having its output coupled to a comparator with the comparator output coupled back to the reset terminal of the flip-flop.          The generator produces pulses at the output of the flip-flop which have durations equal to a constant percentage of the period of the crankshaft position sensor pulses.  The dual slope integrator circuit produces a periodic ramp (saw-toothed) signal which is processed by a clamping circuit and a comparator to produce an ignition dwell pulse which occurs a fixed time before the occurrence of the crankshaft position sensor pulses.  An engine speed monitoring circuit also receives the periodic varying ramp signal produced by the dual slope integrator and via sampling circuitry produces an output signal related to engine speed whose magnitude is updated during each cycle of the crankshaft position pulses.
