Abstract: MATERIAL HANDLING SYSTEM          ABSTRACT OF DISCLOSURE:    A centrifugal pump driven by a tractor draws material, as liquid manure, through a suction hose and discharges the material into one of two discharge hoses.  A first discharge hose directs the material back into the source of material to agitate and mix the material.  The second discharge hose is used to deliver material from the pump to a transport tank spreader.  The pump has a housing rotatably supporting an impeller.  A cone-shaped member connects the inlet side of the housing to the suction hose.  The inlet end of the suc-tion hose has a one-way door valve which allows the material to move into the suction hose and restricts reverse movement out of the suction hose.  The inlet end of the suction hose has an exit opening closed with a movable cover.  The cover can be moved to an open position so that material in the suc-tion hose can drain back into the holding area.  A primer pump mounted on the housing is operable to prime the pump with fluid.

Abstract: ABSTRACT           An electronically operated portable nail driving gun is disclosed.  Nails are driven into a workpiece by a driver blade which is actuated by a solenoid powered by a source of alternating current.  Each actuation of the device produces two successive driving strokes delivered to a nail.  The tool is also provided with means for preventing more than one nail being driven during each actuation of the tool.  A preferred embodiment in which the tool is double insulated is also disclosed as are control circuits which permit operation at either 110 V. or 220 V.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention is directed to a non-clogging flow restrictor that can be attached to a water faucet.  This disc-shaped flow restrictor has a boss in which radially disposed longitudinal slots are formed.  The diameter of the disc, more-over, fits within the spout of a typical faucet.  The narrow slots are greater in length in an upstream direction than the depth of the downstream aperture that penetrates the disc, or the widths of the slots.  These slots trap particulate matter and establish a flow pattern that deposits the solid matter at the radial extremeties of the respective slots to permit stable flow to continue until the slot openings are almost completely obstructed.

Abstract: Abstract of the Disclosure Improved flexible waterproofing membranes of the pre-formed pressure-sensitive or self-adhesive bituminous type particularly useful in roofing are described.  The membranes are in the form of factory-manufactured, flexible, sheet-like laminates employing (a) a lower layer of waterproofing self-adhesive bituminous composition such as rubberized asphalt non-removably adhered to (b) an upper support layer comprised of a laminate of separate, pre-formed flexible sheet materials having different coefficients of linear thermal expansion.  The uppermost sheet material in the support layer (b) has the higher linear thermal expansion coefficient in order that the edges of the applied laminate when exposed to, e.g., solar heating and subsequent cooling, turn downward towards the substrate to be waterproofed resulting in improved sealability.  Additionally, further layers of e.g. protective films and coatings may be applied to the laminates.

Abstract: ABSTRACT OF THE DISCLOSURE                  A centrifugal coating apparatus comprises a mold mounted for rotation about its axis.  The mold includes a melt intake means and a cover.  The mold is kinematically connected with a rotation drive.  The lower sid? of the cover is formed with at least on e guiding slot opened onto the lateral surface of the cover and intended to be filled with a m?lt so as to hold the casting.  A horizontally acting pusher is mounted near the mold and connected with a drive for its motion.  The apparatus is provided with a mechanism for vertically separating the mold and the cover.  The cover is brought by an appropriate mechanism into position permitt-ing the guiding slot to be in parallel relationship with the pusher.  Such an arrangement of the apparatus allows the removal of castings from the molds to be completely mechani-zed and the reliability and the productivity of the apparatus to be upgraded. A multi-station rotary casting machine incor-porating the centrifugal casting apparatus comprises a frame-work mounting a rotary table connected with an indexing me-chanism.  The rotary table mounts vertical spindles adapted to carry molds and kinematically connected with a rotation drive.  There is provided a dispensible crucible positioned underneath the molds at a mold filling station and equipped with a drive for its vertical motion.  Located at a casting removal station are a cover positioning mechanism, a pusher together with its drive and a mechanism for vertically sep-arating the mold from its cover.  A multi-station reciprocat-ing casting machine incorporating the centrifugal casting apparatus comprises a framework mounting a horizontal guide with a carriage mounted thereon.  Spindles connected with a rotation drive and carrying molds are mounted on the carriage in two rows which are perpendicular to the guide.  The spin-dles of each row are combined into an assembly provided with an individual drive for its vertical motion.  The carriage is connected with a drive intended to reciprocate the spind-les between a mold filling station and a casing removal station.  Pushers and cover positioning mechanisms are loca-ted at the casting removal station at the extreme points of the carriage travelling path, and arranged therebetween is a dispensible crucible spaced within a distance equal to that between the rows of the spindles.  Such an arrangement of the apparatus and casting machines increases their relia-bility and preductivity and also allows the casting process to be fully automatized.
