Abstract: INTERNAL COMBUSTION ENGINE          Abstract of the Invention An internal combustion engine is described in which the shape and construction of the gas outlet end portion of a sub-suction path is made operative to inject a gas such as air, an air-fuel mixture or exhaust gas circumferentially into the combustion chamber during the suction stroke.  The gas outlet end portion has a reduced diameter and an injection nozzle which has a length greater than its internal diameter.  Moreover, the gas outlet end portion is constructed of a pipe member which is rotatably and adjustably fitted into the insertion hole of a cylinder head and which is so shaped that the open direction of the outlet end thereof can be changed when it is rotationally adjusted.

Abstract: Abstract A machine for lasting side portions of shoes The machine comprises a shoe support (20) on which a shoe can be positioned, and which includes a tee end engaging member (48) which senses the shoe length, two abutment faces (84, 90) being set along shoe length sensed.  The machine also comprises adhesive-applying nozzles (262) and side lasting rolls (224) mounted on a carriage (216) for movement relative to the last support.  The "start" position of the nozzles is set by valves (334,336) actuated by cams (330,332) positioned by a sensing member (326) engaging with one abutment face (84).  Various other machine operations, which take place at the ball region of the shoe bottom, the position of which region thus varies proportionately with shoe length.  are controlled by further valves (354,356) actuated by cams (350,352) carried as a control rod (344) the position of which is determined by a sensing member (338) engaging the other abutment face (90), an appropriate length grading arrangement (342) connecting said member and said control rod.  The position of the abutment face (84) can be adjusted by the operator to accommodate different shoe styles.

Abstract: ABSTRACT The invention provides a rubber composition co-vulcanizable with a sulfur cure system, the composition comprising 95 to 20% by weight of a partially hydrogenated unsaturated nitrile-conjugated diene copolymer rubber in which at least 50% of units derived from the conjugated diene are hydrogenated, 5 to 80% by weight of an ethylene-propylene-nonconjugated diene terpolymer rubber, and a required amount of at least one vulcanization accelerator selected from the group of thiuram accelerators and dithiocarbamate accelerators.  The rubber composition of the invention exhibits the excellent oil and ozone resistance of its two rubber components and shows a higher tensile strength and heat aging resistance than that which would have been brought about by the mixing of the two rubbers. The rubber composition is particularly useful in such areas that require the above properties, for example, automotive brake hoses, automotive radiator hoses, transmission belts, conveyer belts, sheets and rolls.

Abstract: Abstract Adjustable-Beam Permanent-Magnet-Focused Linear Beam Microwave Tube A permanent-magnet-focused linear-beam high power millimeter-wave tube is externally adjustable for optimum electron beam optics during initial tube operation.  The adjustment is made possible by pro-viding an enlarged cavity within the cathode pole-piece within which is housed a confined-flow mag-netically-focused electron gun, and a cylindrical insert of magnetic material axially symmetrically disposed about the gun and in spaced relationship to and adjacent the gun insulator envelope.  The insert may comprise iron or a radially magnetized permanent magnet, either alone or in combination, and more than one insert of magnetic material may be concen-trically employed.  In this manner, and by movement of the insert axially within the cavity toward and away from the gun, a finely controllable smooth adjustment of the beam diameter in the beam-microwave interaction region of the tube is effected over a wide range during initial operation.  Substantially only the magnetic field in the vicinity of the gun is affected, and essentially no scalloping degra-dation of the beam in the interaction region is observed.

Abstract: Abstract Federal Specification DD-G-1403B requires heat-strengthened glass to have a surface compression stress not less than 3500 pounds per square inch nor greater than 10,000 pounds per square inch and an edge compression stress that is not less than 5500 pounds per square inch.  Large windows conforming to this specification are believed to have little likelihood to develop dangerous islands of glass that separate from the glass sheets when they fracture.  The present invention provides method and apparatus to develop heat-strengthened glass sheets of large dimensions such as used for commercial construction that develop suitable break patterns when fractured.

Abstract: PROCESS OF MANUFACTURING AND USING  GAUGES FOR VERIFYING THREADS OF        TUBULAR MEMBERS            Abstract of the Disclosure A ring gauge is made from the box end of an authenticated precision threaded member and a plug gauge is made from the pin end thereof.  The pin end is machined laterally and radially at its nose to ensure complete engagement of the threads.  The box end is machined laterally and radially at its internal shoulder for a similar reason.  A plunger-activated seal-diameter gauge operates through a radial hole in each of the ring gauge and plug gauge thus made, so that the plungers contact the sealing surface of a measured pin end or box end.          Similarly, a plunger-activated standoff gauge operates through a longitudinal opening of the ring gauge and of the plug gauge, the plungers effectively providing a measurement of standoff between the tip of the pin end being measured and the internal surface of the ring gauge shoulder or comparable standoff of the box end.  Tabulated measurements of seal diameter and standoff provide data for determining the optimum number of acceptable fits between the pin ends and box ends from a plurality of measured tubular members.  Similar gauges, but segmented with a gap, are used to measure taper of the measured threads.  The gap size in the gauge determines if the measured taper is slow or fast relative to nominal and, if calibrated, an absolute measurement of taper.
