Abstract: ABSTRACT OF THE DISCLOSURE Band ply lubricants, sometimes referred to as inside tire casing lubri-cants or inside tire dopes, are used as friction reducing and surface protective coatings during the cure of bias ply tires in particular and are applied inter-mediately between the interior surface of the green tire carcass and the exterior surface of a rubber bladder.  A silicone and volatile hydrocarbon free, water reducible paste product comprising a zinc soap of a long chain fatty acid (zinc stearate), a long chain fatty acid ester of sorbitan, an alkylene oxide alkylene glycol polymer and mica, which are combined to produce a paste which is reduced to application viscosity by spraying with approximately an equal weight of water, is provided to eliminate the more costly emulsions and hydrocarbon solvent con-taining inside tire curing lubricants without sacrifice in quality.

Abstract: 233-P-US02244 METHOD AND APPARATUS FOR REDUCING OPERATING NOISE OF THE AIR-CARBON ARC CUTTING AND GOUGING PROCESS ABSTRACT OF THE DISCLOSURE The operating noise level of the air-carbon arc cutting and gouging process can be reduced by controlling the air velocity in the area where the air impinges on the arc column to between 90 and 170 feet per second. Further noise reduction can be achieved through selection of electrode composition, sound attenuat-ing material juxtaposed to the operator's ears, control of arc voltage level and electrode stick-out. Velocity control can be achieved by modifications to existing air-carbon arc cutting and gouging torches.

Abstract: OIL PUMP FOR HERMETIC COMPRESSOR   .                 ABSTRACT OF THE DISCLOSURE          A hermetic refrigeration compressor has a two-stage oil pump in the vertically aligned crankshaft that is jour-naled in a combination thrust and radial bearing at the bottom of the crankshaft.  The oil passes upward through an axial passage in the crankshaft and then outward through a radial passage which comprises the first stage of the pump. The oil then passes through a wide and shallow groove around most of the periphery of the crankshaft and is then returned through a second radial passage to another vertical passage offset from the axis of the crankshaft to move the oil upward to lubricate the various moving parts of the compressor.

Abstract: Abstract:   The invention relates to a spray valve assembly for an aerosol can.  The valve is capable of allowing the can to operate properly either in the normal or inverted position. This is achieved by providing a main passage through the assembly and an auxiliary passage.  An auxiliary valve is located in the auxiliary passage and is arranged to open the main passage only in the normal position of the can and the auxiliary passage only in the inverted position.          The auxiliary valve is formed eccentrically in the valve housing portion which surrounds the auxiliary valve cham-ber, and the predominant part of the cross section of the main passage extending by the auxiliary valve is disposed on the side which is towards the axis of the valve hous-ing, of an auxiliary valve axial plane which is disposed perpendicularly to a common axial plane of the valve housing and the auxiliary valve chamber.  This minimizes flow resistance and consequently flow losses.

Abstract: ABSTRACT OF THE DISCLOSURE         A load measuring device which operates with a small amount of vertical travel is provided herein.  The load measuring device includes a base with a thin sealed, fixed volume reservoir for a load-transmitting material (e.g., a soft rubber disc) forming the lower portion of the base. A flexible diaphragm which seals the thin reservoir is provided which is in direct contact with the load-transmitting material in the reservoir.  A platform is provided for applying a load directly to the diaphragm. Finally, a transducer including an integral diaphragm at the base thereof is held with such diaphragm in direct contact with the diaphragm to provide a reading which is proportional to the absolute value of the load.  Thus, a sealed, shockproof load-transmitting cell is provided whose manufacture is greatly simplified and whose cost is reduced both in terms of time and material.  Moreover, its installation in a weight scale is much simplified since there is no hydraulic connection needed between the load cell and the transducer.

Abstract: ABSTRACT     A jar tool for use in a drill string for use in dislodging a drill bit or well-tools trapped in well bores.  The tool comprises an outer housing adapted to move longitudinally with respect to an inner spline mandrell.  A piston assembly is acted on by a piston actuator and hydraulic fluid restricts the movement of the piston assembly and, therefore, the movement of the mandrell relative to the housing, while the piston assembly is within a narrower portion of a hydraulic cylinder.  When the piston assembly reaches a larger diameter portion of the cylinder, the hydraulic fluid rushes past the piston assembly which allows a knocker connected to the spline mandrell to collide with the outer housing.  A compression spring returns the piston assembly to its rest position abutting a shoulder on the outer housing.  Provision is made for a valve to be inserted in the piston assembly so that the system can be temperature compensated and more desirable hydraulic fluids can be used.

An authorized receiver with knowledge of a private deciphering key, a modulus and an integer multiplier generates a private enciphering key which is employed in further enciphering the received enciphered message to form a doubly enciphered message.  The doubly enciphered message is deciphered using the private deciphering key alone to recover the original data message.

Abstract: ABSTRACT OF THE DISCLOSURE:     Machine including a powered truck-like vehicle having a support base at the rear end and an apparatus for cutting a drive-in passage across a concrete curbstone, a sidewalk or the like.  The apparatus is mounted on the base and essentially comprises two spaced parallel booms mounted at one end on the base and an elongated bridge structure extending between and perpendicularly to the booms, being connected to them and pro-vided with a drive so that it can be displaced along the booms with respect to the support base of the vehicle.  The booms and bridge structure are pivoted from an inoperative position where the bridge structure is above the support base to an operative position where the booms and bridge structure are swung outwardly of the support base in a position for cutting the curbstone, sidewalk or the like.  A carrier, having a con-crete rotary cutting saw, is mounted on the bridge structure and displaceable in a first direction along one face of the structure, the saw itself being displaceable along a second direction which is perpendicular to the first mentioned direction.  In this manner, with the apparatus in the operative position, the rotary saw is first advanced in the second direction through the curbstone, sidewalk or the like and then in the first direction to cut an elongated slot determining the elongated extent of the drive-in passage.
