Abstract: ABSTRACT   A cable splice, tube joint, or the like, is covered by a fitting constructed as a split hose provided along one edge with a rail made of metal or a strong synthetic.  A similar rail element or an integral fastening ele-ment is provided on the other edge and secured to the first rail by welding, adhesive bonding, or soldering in order to obtain a joint which resists tension and compression.  The hose has been laterally slipped onto and over the cable splice or tube joint and, after the split joint has been sealed (or concurrently therewith), the hose is heat-shrunk.  Various rail configura-tions are shown; a method of making the hose is explained.

Abstract: ABSTRACT         A reclosable package for products such as sliced meat, cheese, etc., includes a thermoplastic forming web having a cavity formed therein with a peripheral flange around the opening to the cavity.  The product is located in the cavity.          A closure strip has one surface thereof sealed to the forming web, the strip being adjacent and parallel to but spaced apart from one edge of the forming web.  A portion of the strip at each end thereof has an indentation.  A covering web is sealed to the peripheral area of the forming web thereby hermetically enclosing the product and closure strip.  The indentation at each end of the strip permits a continuous, smooth seal between the covering web, forming web, and closure strip in the vicinity of the indentations.

Abstract: IMPROVED INLET CONTROL VALVE Abstract of the Disclosure The inlet control valve described herein is use-ful in connection with pneumatic tools or the like that include a hollow tool body containing an air motor.  A control valve is disposed in an inlet passageway extending to the air motor.  The valve includes a first valve member that has a seal engaging an annular valve seat.  A second valve member extends through a bore in the first valve member and is disposed in sealing engagement with a second annular seal member carried by the first valve member.  The second valve member includes an operating member that also extends through the bore into engagement with the trigger mechanism of the tool so that displacement of the trigger to a first position tilts the second valve member off its seat permitting restricted flow through the passageway. Additional movement of the trigger displaces the first or main valve member off its seat permitting the maximum flow through the passageway.

Abstract: ABSTRACT OF THE DISCLOSURE     The instant invention concerns a cartoning assembly which operates in conjunction with a sheet stacker to pile sheets directly in their carton. The assembly loads a three-sided carton having an open top into the stacker and supports the carton there such that sheets accumulate in the carton.  After a predetermined number of sheets have been piled in the carton, succeeding sheets piling into the stacker are segregated and separately supported away from the predetermined pile.  The carton is then transferred to a discharge conveyor for processing and lidding.  Meanwhile. 2 further carton is loaded into the stacker and supported beneath the succeeding pile.  The succeeding pile is then deposited into the further carton.  The further carton is supported in the stacker until the Predetermined number of sheets accumulate and the process repeats.

Abstract: ABSTRACT Poly(ethylene terephthalate) resin and blends of poly(ethylene terephthalate) resin with other polymers are extruded while being coupled with an organic diisocyanate under conditions where carbon dioxide gas is vented smoothly, as it is formed.  The extruder has a number of zones designed to perform specific functions.  The temperature in the kneading zone and in the venting zone must be maintained at about 280-320°C to bring about rapid reaction and to permit efficient gas evolution and removal without thermally degrading the polymeric material.  The extruded article is free of trapped gas bubbles and other imperfections.  This process is particularly suitable for making PET billets, which then are stretched to form strapping useful in packaging applications.
