Abstract: ARRANGEMENT FOR MULTI-ORIFICE INK JET PRINT HEAD       ABSTRACT OF THE DISCLOSURE    Recording arrangement in which a row of ink jet nozzles is inclined with respect to the relative motion of a recording surface to permit the variously and selectively charged drops from each nozzle to be de-flected by a single pair of planar electrostatic deflection plates common to all nozzles and parallel to the row so that each nozzle is capable of producing marks at regularly spaced locations along a plurality of parallel rows.  Also disclosed is a method of determining the angle of inclination.  The inclination angle, nozzle spacing, and deflection levels are pre-ferably chosen so that marks can be placed at all possible data points by a single row of nozzles in a single recording pass.  The disclosed method also provides for recording in either direction, the use of two or more parallel nozzle rows, and for the inter-lacing of drop marks at the recording surface.

Abstract: HYDRAULIC HAND JACK     Abstract of the Disclosure A hydraulic jack is disclosed, of the type comprising a ram having a head portion reciprocable in a cylinder between two cylinder ends, and sealing means carried on the ram head portion to provide a substantially fluid-tight seal between the ram and the cylinder interior surface.  In this jack, an open sided pressure relief trough is formed in the interior surface of the cylinder adjacent one end to permit the flow of fluid past the sealing means when the head portion is located sub-stantially adjacent the cylinder end and relief trough.  Fluid bleeding action past the relief trough thus prevents forcing the ram head and sealing means against the cylinder end.  When the jack is so constructed, the sealing means can include an elastomeric seal cup member which will not be damaged by its travel past the trough.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for developing latent images of X-rayed objects on dielectric receptor sheets has a carrier which advances receptor sheets along a circular path about a horizontal axis.  A tank with an open top is installed below the six o'clock position of the carrier and contains a horizontal developing electrode having narrow elongated channels extending in parallelism with the axis of the carrier.  A pump draws liquid developer from a vessel in which the tank is confined and admits the developer into the bottom zone of the tank wherein the developer rises to fill and rise above the channels of the electrode and to thereby contact the latent image of a sheet on the moving carrier.  The surplus of liquid developer overflows the upper edge of the tank and returns into the vessel.          The electrode is movable up and down by rotary eccentrics to thereby influence the development of latent images, especially the development of outlines of dark portions of the images.

Abstract: Abstract of the Disclosure The leaching action of a nitric acid leach liquor on a sulfidic ore is potentiated by intimately admixing an oxygen containing gas through the reacting slurry during treatment.  This procedure results in the ratio of nitrate consumed to metal values leached remaining substantially constant at a relatively low level through-out the leaching procedure and in a significant reduction in the volume of off-gases normally produced.  The process also reduces or eliminates the evolution of nitric oxide.

Abstract: ABSTRACT     A disposable aortic perforator has an elongated stem with an exterior stem surface circular-cylindrical about a longitudinal axis and extending between a far end and a near end.  A coaxial disc having an exterior circum-ferential cylindrical disc surface of a first predetermined diameter is separated from the remainder of the stem by an intervening groove leaving an axial shank therebetween.  The coaxial disc has a near surface on said disc normal to the axis and meeting the disc peripheral surface substantially at a right angle to form an abrupt outside corner.  An elongated tube is telescoped over the stem and is slidable a predetermined distance, about one-third of an inch, in the stem.  The tube has an interior, circumferential cylindrical or tube surface of a second predetermined diameter about .0002 inches larger than the first predetermined diameter of the stem.  An annular surface at the far end of the tube and normal to the axis meets the interior tube surface sub-stantially at a right angle and forms an abrupt inside corner.  A cross bar normal to the axis engages the stem and prefer-ably is disposed in a jacket slidable on or with respect to the tube.  A spring is interposed between the stem and the tube for urging the tube axially away from the disc, the motion being limited by interengagement of slots in the tube with the cross bar.

Abstract: ABSTRACT OF THE DISCLOSURE     The sound support comprises an address track with coded words dividing the sound support into consecutive sections, each associated with a particular address. The positioning of the sound support is controlled in such a manner as to advance a section of the sound support bearing a predetermined address, to the level of a reading head. The video support comprises images, each associated with a particular address, and its positioning is controlled so as to advance in front of a projection gate an image having a predetermined address. The simultaneous running of the sound and video supports are then controlled, the speed of image projection being able to vary and being controlled according to pre-recorded instructions on a control data support, the access to which is neither related to the advance motion of the sound support nor to the image support.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved cloth-handling machine in which the energy input necessary for evaporating and conducting away water from clothes being dried is minimized.  The machine is a tumbler drying or a combination washing/drying machine and includes a casing having a radiant heater disposed adjacent a reflector in its upper portion adapted to heat a tumbler drum rotatably mounted within the casing.  Air is withdrawn from the drum and moisture is condensed from the air which is then recirculated back to the interior of the drum.  A condenser arrangement, positioned outside the casing, is comprised of an air turbulator portion connected to a drain opening at the bottom of the casing.  A spray or mist of cooling water is supplied by way of a nozzle 22 mounted between the turbulator and the drain opening.  The turbulator is followed by 2 filter and a tranquillizing duct leading through a sump to a pump having a syphon-type outlet.  From the tranquillizing duct recirculated air is drawn by an impeller and is moved through an air passage between the radiant heater and reflector, so as to be heated and is thence supplied to the interior of the drum by a nozzle projecting through the usual charging opening of the drum.

Abstract: ABSTRACT OF THE DISCLOSURE     An ice skate scabbard of the type comprising two generally identical halves with spring means for urging the two halves to-gether by exerting a force generally along the runner of the skate.  The two halves are each molded from a suitable plastics or rubber material.  In order to maintain alignment between the two halves, a slide tongue protrudes from one half and is received in a correspondingly shaped passage in the other half. Accordingly, the two halves are maintained in alignment prior to, during and after securement of the scabbard to the blade. When the scabbard is applied, the aligning tongue extends along the edge of the skate runner thus providing protection of the the runner edge extending between the two halves.  Each of the two halves has a dual slot: one of a relatively large radius, generally adapted to fit the column of the new type of "TUUK" (trademark) blades, while a relatively small  lot is provided in the bottom of the former to house the runner of the skate.  Drainage openings are provided in the bottom of the runner receiving slot to allow for natural flow of molten ice or the like from the skate runner area, with the scabbard on.      The scabbard improves the protection of the skate while improving the convenience of attaching or removing same to or from the blade.  The scabbard is suitable for virtually any kind of blades, from figure skate blade to the the most recent models of hockey blades.
