Abstract: A folding cover for a pickup truck bed includes an improved adjustable front hinge support for mounting the cover that permits the front panel to be opened and permits lateral, vertical, and longitudinal adjustment of the cover position. A wire spring latch fastens the front panel in a closed position and provides for vertical latch position adjustment. A rear panel side latch is opened with a depressible latch opener at the rear of the cover. An intermediate panel latch fastens the intermediate panels down at the side of the pickup truck bed. These latches release automatically when the cover is folded. Another intermediate panel side latch has a wire spring pin that can be manually or automatically disengaged. The cover also has wind deflecting sloped side edges integral with the panel frame and hinges integral with the panel frame. Novel seals seal the junctions between adjacent panels.

Abstract: A piston pressure regulator has a body, a corresponding piston, and a floating seal. The body includes an interior piston cavity, a low pressure port connected with the piston cavity, and a high pressure port connected with the piston cavity. Further, the piston cavity has a length. The corresponding piston is located in the piston cavity and cooperates with the piston cavity to define low pressure and high pressure portions of the piston cavity and low pressure and high pressure sides of the piston. The piston also slides along the piston cavity length, between the low and high pressure ports. The seal is a wafer member that is interposed between the piston and the high pressure port. The seal is separate from each of the piston and the high pressure port to "float" between the piston and the high pressure port. Seals of different thicknesses may be substituted to adjust the operating pressure.

Abstract: A vacuum dryer panel for a leather drying machine wherein a dryer panel comprising a porous screen is mounted over a perforated plate on the underside of a vacuum chamber positioned above a heated drying table on which leather skins are dried. The dryer panel comprises a layer of fine mesh screen preferably formed of a synthetic resin material mounted on a porous backing preferably formed of a synthetic resin material. The backing material is adapted to be mounted adjacent an outer side of the perforated plate and provides porosity between the screen and adjacent openings of the perforated plate. The backing material is sufficiently rigid to prevent the screen material from being pulled into openings in the perforated plate by a negative pressure on the upper side of the plate, so as to prevent marks in the dried leather. The edges of the dryer panel are folded over and incorporate reinforcing strips. Threaded fasteners fit through spaced openings in the edges for mounting the dryer panel to a vacuum chamber.

Abstract: A vented colostomy pouch includes a water proof bag having a waste aperture and a vent aperture, with an annular member being secured to the vent aperture and a plug type closure being removably connectable to the annular member to seal the vent opening. The plug and annular member are integrally formed as a unitary member from a plastic material with a flexible attachment interconnecting the annular member and plug. The attachment is deflectable to permit the plug to be inserted and removed from the annular member. The plug has cylindrical side walls that resiliently fit into mating sidewalls in the annular member, with sidewall friction being sufficient to prevent dislodgment without manually moving the plug. The plug is at least slightly longer than the annular member so that the plug clears the opening in the annular member when fully inserted.

Abstract: A material processor having an enclosure with an ingress to receive material into the enclosure, and a discharge to remove homogenous material from the enclosure. A spindle is located in the enclosure, has a longitudinal spindle axis, and is rotatable about the spindle axis. A drive is operatively connected with the spindle to rotate the spindle about the spindle axis. A centrifugal sieve is located in the enclosure and coupled with the spindle. The ingress feeds material into the sieve. A conveyor is connected with the discharge to transfer mixed material from the enclosure. The conveyor further has a generally cylindrical tube with a tube diameter, two opposing ends, and a tube axis extending through the ends. A helical blade extends along the tube axis between the two ends and is rotated about the tube axis. More particularly, the helical blade may have a series of blade tips that are spaced along the tube axis.
