Abstract: 12                  48,270 ABSTRACT OF THE DISCLOSURE An  improved  low voltage vacuum switch is de-tailed which is operable to interrupt high D.C. continuous currents at voltages below the arc potential.  An improved arc shield is provided which ensures that the switch can withstand significant D.C.  overvoltages across the con-tacts when the switch is in the open position, even after repeated switch operation.  The arc shield means comprises spaced-apart generally conic shield extending in parallel relationship from opposed ends of the switch with substan-tial overlap of the conic shields.  These conic shields are disposed at an angle relative to the switch axis and minimize  the  chance  for vaporized  contact material  to reach and condense upon the switch insulator body portion.

Abstract: DIFFERENTIAL MEASURING SYSTEM  Abstract of the Disclosure An apparatus for measuring the differential be-tween a plurality of physical quantities, such as tem-perature, includes transducers 10 and 12 each positioned to sense the physical quantity.  The transducers are preferably of the resistive or nonreactive variety.  A single, controlled current power source 15 is connected sequentially to the transducers through a switching cir-cuit 20.  Each transducer is connected to the switching circuit and to an amplifier 40 through four-conductor cables 35, 45.  The amplifier is therefore connected continuously to the transducers to sense both the volt-age developed thereacross when the transducer is con-nected to the source of current through the switching circuit and also to sense continuously any other voltages, such as those that might be produced by thermocouple ef-fects.  The output of the amplifier 40 is applied to a linearizing circuit 50 whose output is used to control the magnitude of the output current of the current source 15 in response to the absolute resistance of each trans-ducer.  The switching circuit 20 is controlled by a clock 30 the output of which also controls a synchronous de-modulator 55 which is connected to the output of the amplifier means for sampling the peak-to-peak output of the amplifier after all transients have decayed.

Abstract: ABSTRACT OF THE DISCLOSURE           Substantially rectangular panel lengths are preformed from metal or synthetic plastic sheet and include a plurality of troughs in spaced and parallel relationship with shaped side edge portions, one on each side of the panel.  The  side edge on one side includes a vertical portion, a horizontal portion extending outwardly therefrom at the upper side of the vertical portion and an angulated downturned lip or flange on the outer side of the horizontal portion.  The other side edge includes a short vertical portion, an inwardly and upwardly extending portion extending from the upper edge of the vertical portion, a horizontal outer portion extending from the upper edge of the inwardly and upwardly extending portion, and a downturned vertical portion extending from the outer edge of the horizontal portion.  The first edge of one panel engages over the second edge of the adjacent panel with the vertical portions in contact with one another.  The panels are secured together through the vertical portions by blind rivets or other fastening means so that the horizontal portion and the downwardly and outwardly extending lip or flange of the first side edge overlies and shields the junction between adjacent panels without the necessity of sealing material.  The panels nest one above the other in stacked relationship for storage and transportation purposes prior to assembly.

Abstract: FN 915,446 PHOTOSENSITIVE COMPOSITIONS AND ARTICLES                 Abstract of the Disclosure Photoreactive lithographic printing plate compositions ordinarily require organic solvents and/or aqueous alkaline solutions to develop the image after exposure to light.          The use of such solvents or solutions for development requires an additional expense in the use of lithographic plates above the cost of the plates and requires the user to store development solutions and solvents.          The present invention provides a truly water developable photoreactive printing plate composition.  The plates constructed according to the present invention may be readily developed by pure water.

Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a method and apparatus for reproducing a musical presentation wherein musical data, from such presentation, such as keyboard actuations of a keyboard-type musical instrument, is encoded and stored in a code which has information contained in the transitions only and the sense and direction of such transitions are ignored.  This avoids several major drawbacks of bi-phase level code previously disclosed because the (1) phase of the signal need not be maintained, and (2) the bi-phase level code cannot be recovered following a dropout until a 1-0 or a 0-1 transition occurs.  There is also disclosed a data dropout detection system for assuring that the wrong music is not played.

Abstract: ABSTRACT OF THE DISCLOSURE     A tire-changing machine includes a framework supporting a wheel rim receiving platform adapted to receive and secure a wheel rim thereon.  A bead breaker mechanism includes a bead breaker shoe, and the shoe is operatively connected to a bead breaker drive lever so that the bead of a tire mounted on the rim may be engaged by the shoe and broken away from the rim.  A bead breaker shoe support arm has the shoe fastened to one end thereof, and a bead breaker column lock member has a channel therethrough in which the shoe support arm is slidably engaged, so that the support arm is adjustable in lateral position to bring the shoe to overlie the tire bead. A bead breaker support column provides a mount for the column lock member and is pivotally connected to the bead breaker drive lever at one end, so that a force component applied to the shoe in a direction parallel to the support column causes a friction force between the lock member and the shoe support arm sufficient to arrest motion of the shoe support arm in the channel.
