Abstract: ABSTRACT OF THE DISCLOSURE   A method and apparatus for making a twin-wall internally corrugated plastic structural part provided with a smooth, dense, solid, thin walled, non-cellular skin comprising injecting a thermoplastic or resin material into a pair of closed mold members which define a scaled cavity. A small amount of plastic material is initially injected into the cavity with the material impinging upon and being dispersed over the mold members thereby forming a generally continuous thin skin substantially the mold surfaces. Thereafter, successively and intermittently injecting an inert gas under pressure through one mold member during continued injection of the plastic material into the cavity thereby pressurizing the skin against the walls of the mold cavity and progressively commingling the inert gas under pressure and the inwardly flowing plastic material as both enter the cavity until the cavity is filled with an internal corrugated body integral with and bonded to the skin. Further steps include cooling the twin-wall internally corrugated structural part to permit the same to solidify as an integral unit and venting the mold cavity to atmosphere to relieve pressure from the corrugated plastic structural part. The intermittent injection of the inert gas introduces minute amounts of pressurized gas into the continuously injected plastic material.

Abstract: PUMP FOR A PORTABLE VENTILATOR                          ABSTRACT     A pump primarily intended for use in a portable ventilator.  The pump includes a piston-cylinder arrangement in which the piston is reciprocally moved within the cylinder by rotating a shaft.  The shaft is threaded and mounted for rotation within the cylinder at a fixed location along the axis of the cylinder.  The piston has an aperature through its center and the shaft extends substantially between the end walls of the cylinder and through the center of the piston.  The piston is held against rotation relative to the shaft and cylinder by a collapsible hinge and is attached to the shaft by an arrangement including a ball nut and sealing nut.  The piston forms a variable volume, working chamber with one end of the cylinder and in operation, the shaft is selectively rotated to move the piston toward and away from the end wall.  This positioning of the shaft within the cylinder reduces the overall size of the pump and specifically adapts it for use in a portable ventilator in which size limitations are critical.

Abstract: PROCESSES FOR THE PREPARATION OF SILVER HALIDE EMULSIONS OF CONTROLLED GRAIN SIZE     DISTRIBUTION, EMULSIONS PRODUCED THEREBY, AND PHOTOGRAPHIC ELEMENTS Abstract of the Disclosure A process is disclosed of producing photo-graphically useful radiation sensitive silver halide emulsions the grains of which are of a predetermined size distribution, including selection of maximum and minimum grain diameters find selection of the distri-bution of grains of maximum, minimum, and intervening diameters.  This is achieved by modifying a double jet precipitation to introduce during the run stable silver halide grains capable of acting as host grains for the deposition of additional silver and halide ions. The degree to which the host grains initially introduced are grown determines the maximum grain diameter of the emulsion. The minimum diameter of the grains in the emulsion produced can be determined by the diameter of the stable silver halide grains introduced at the end of the run. The rate at which the stable host grains are introduced during the run controls the distribution of intervening grain sizes.         The silver halide emulsion produced in various forms can be comprised of silver halide grains differing in diameter such that (a) the relative frequency of grain size occurrences is relatively invariant over much of the range of grain sizes present; (b) the maximum relative frequency of grain sizes occurs near the minimum grain diameter of the emulsion; (c) the maximum relative frequency of grain sizes occurs near the maximum grain diameter; or (d) maximum relative frequencies of grain sizes occur near both the maximum and minimum grain sizes.
