Abstract: ABSTRACT   A measuring system particularly for measuring the length of a moving vehicle comprises a pair of detector stations spaced a known distance apart along a path of vehicle movement each detector station comprising a vertically extending series of electromagnetic radiation beam-emitters disposed on one side of the path and at least one detector disposed on the other, The beams from the emitters are aimed at the detector so that each part of the vehicle when disposed between the emitters and detector will interrupt some of the beams to produce a characteristic quantity of incident electro-magnetic radiation on the detector which will serve to identify that part of the vehicle. Data processing means are provided for processing the outputs from the detectors at the two stations to provide a velocity related vehicle measurement.

Abstract: 1176.002 S P E C I F I C A T I O N                JULIENNE CUTTER TOOL AND METHOD           OF MAKING               Inventor:  WILLIAM A. WILLIAMS, JR.                 ABSTRACT OF THE DISCLOSURE     A julienne cutter tool and method of making are described, the cutter being intended for use in rotary food processing apparatus of the type having an upright working bowl with a vertical motor-driven tool shaft extending up into the bowl.  The julienne cutter has a hub engageable with said tool shaft for rotating a horizontal disc-like member carrying a primary blade horizontally positioned at an elevated location above the upper surface of said disc member and extending from a smaller radius region to a larger radius region.  An opening defined by said disc member permits the food material which has been cut by said primary blade to move downwardly through the disc member, and a plurality of individual radially-spaced secondary blades located in said opening in respective planes perpendicular to said primary blade neatly slice the food material into julienne strips.  These secondary blades are formed by slitting a strip of sheet blade metal for providing a plurality of tabs integrally attached to a planar base portion of the blade strip and then bending each tab perpendicular to the plane of said base portion and sharpening each tab, said base portion being attached to said disc member with said sharpened tabs extending into said opening for providing the secondary blades.

Abstract: ABSTRACT    A workpiece supporting and clamping arrangement includes supporting structure defining a supporting surface.  A first top member having an upper surface is supported by the supporting structure on the supporting surface.  A second top member like-wise has an upper surface and both upper surfaces lie in a sub-stantially horizontal plane.  The top members also have respect-ive mutually adjacent side walls defining clamping surfaces.  A guiding structure is provided for guiding the second top member relative to the supporting structure.  The second top member can be moved along the guiding structure so as to adjust the position of the second top member with respect to the first top member.          The guiding structure is pivotally mounted so that the second top member can be rotated from a first position on the supporting surface whereat the upper surfaces of the top members are in the same horizontal plane to a second position whereat the second top member is in a plane transverse to said horizontal plane so as to cause the clamping surfaces and the supporting surface to con-jointly define a three point clamping system.  In the first position, the clamping arrangement is suited for clamping work-pieces having two surfaces that are substantially parallel to each other; whereas, in the second position, the clamping arrange-ment is especially suited to clamping workpieces having a cylin-drical or polygonal shape such as, for example, a section of tubular conduit.

Abstract: ABSTRACT OF THE DISCLOSURE An apparatus and method for determining fluid density and for gel strength comprising a conduit having two isolation diaphragms spaced verti-cally apart therealong, a pump means for passing a fluid through said vertical conduit, and means for alternation flow and static conditions of the fluid in said conduit.  The isolation diaphragms are connected through conduits containing noncompressive fluid with a differential pressure transducer.  The pressure transducer is connected to a gauge or other reporting and/or recording device such that the true density of the fluid is determined by the pressure differential between the isolation diaphragms when the fluid is static and an estimation of the gel strength of the fluid is determined by the increase in the apparent density of the fluid during flow at low flow rates.

Abstract: ABSTRACT          A self-supporting sheet is provided with a composite release surface which exposes separate areas of (1) a solid fluorochemical polymer having defined surface energy properties and (2) a cured silicone polymer.  The composite release surface, which may be applied either to one or both foils of a release liner or to the back of pressure-sensitive adhesive tape, is prepared by first applying a solution to the fluorochemical polymer, evaporating the solvent and then overcoating with silicone-forming reactants.  Pressure-sensitive adhesives have an average adhesion to the composite release surface which is less than to the fluorochemical polymer alone and greater to the silicone polymer alone.

Abstract: ABSTRACT                  Machine tools, particularly gas cutting torches are commonly controlled by pattern tracers. Under some circumstances, it is desirable to cut off the end of a cylindrical tube in the form of a complex curve so that the tube may be joined to another surface. For example, where it is desired to weld one tube onto  another tube, this invention provides apparatus for cutting the end off the tube in accordance with a predetermined pattern. The pattern can be traced by a pattern tracer.  The tube so cut can then be used for fabrication of complex structures.

Abstract: ABSTRACT OF THE INVENTION   Hollow glass microspheres made from a low-heat conductivity glass composition containing a high vacuum and a thin metal coating deposited on the inner wall surface of the microspheres are described.  The hollow glass microspheres are used to make superior insulation materials in the construction of highly efficient solar energy collectors.    The hollow glass microspheres are made by forming a liquid film of molten glass across a coaxial blowing nozzle, applying a metal vapor blowing gas at a positive pressure on the inner surface of the glass film to blow the film and form an elongated cylinder shaped liquid film of molten glass.  A transverse jet is used to direct an inert entraining fluid over and around the blowing nozzle at an angle to the axis or the blowing nozzle. The entraining fluid as it passes over and around the blowing nozzle fluid dynamically induces a pulsating or fluctuating pressure field at the opposite or lee side of the blowing nozzle in the wake or shadow of the coaxial blowing nozzle.  The continued movement or the entraining fluid over the elongated cylinder produces asymmetric fluid drag forces or, the cylinder and closes and detaches the elongated cylinder  from the coaxial blowing nozzle and the detached cylinder by the action of surface tension forms into 2 spherical shape.      Quench nozzles are disposed below and on either side of the blowing nozzle and direct cooling fluid at and into contact with the molten glass microspheres to rapidly cool and solidify the molten glass to form a hard, smooth hollow glass microsphere and to cool and condense the metal vapor and to deposit the metal vapor on the inner wall surface of the microsphere as a thin reflective metal coating or transparent metal coating.    The hollow glass microspheres can also be made to contain a thin transparent or reflective metal coating deposited on the inner wall surface of the microspheres by adding to the blowing gas small dispersed metal particles and/or gases of organo metal compounds and decomposing the organo metal compounds.    The hollow glass microspheres can be made from low heat conductivity glass compositions.  The microspheres can be used to make improved insulation materials and composites and insulating systems.    The hollow glass microspheres can be used as filler materials in plastics, in plastic foam compositions and in concrete and asphalt compositions.    The hollow glass microspheres can also be made in the form of filamented glass microspheres with a thin glass filament connecting adjacent glass microsperes.
