Abstract: An apparatus for the accurate formation of a three-dimensional article comprises providing a first quantity and a second quantity of substantially uniform size droplets of a desired material wherein each droplet has a positive or negative charge. Each quantity of droplets is focused or aligned into a narrow stream by passing the droplets through or adjacent an alignment means which repels each droplet toward an axis extending through the alignment means. The droplets are deposited in a predetermined pattern at a predetermined rate onto a target to form the three-dimensional article without a mold of the shape of the three-dimensional article. The droplets of the first quantity and the second quantity are supplied at different distances, whereby the droplets of the first quantity bond to each other and the droplets of the second quantity do not bond to each other or to the first quantity of droplets.

Abstract: The present relates to an method to produce a molding apparatus for molding plastic parts which comprises a cavity insert and a core insert wherein each insert has an open area on the shell or back side thereof. A device for circulating fluid through each chamber cools the inserts. In one preferred embodiment, the cavity and core inserts are made using a mold having a ceramic formulation including generally uniform size aggregate materials and carbon fibers. In certain embodiments, the apparatus further includes pressure bearing devices, for absorbing molding pressure during operation of the molding apparatus.

Abstract: An apparatus for the accurate formation of a free-form three-dimensional article comprises providing a supply of substantially uniform size metal droplets of a desired material wherein each droplet has a positive or negative charge in an enclosed environment. The supply of droplets is focused or aligned into a narrow stream by passing the droplets through or adjacent an alignment mechanism which repels each droplet toward an axis extending through the alignment mechanism. The droplets are deposited in a predetermined pattern at a predetermined rate onto a target to form the three-dimensional article without the use of a mold of the shape of the three-dimensional article.

Abstract: A dry break coupling for joining together opposing passageways includes a male member and a female member, each of which includes a resiliently deformable rubber flap with cross-hair slits positioned to engage each other as the male and female members are moved axially toward their coupled position. Each of the male and female members also is provided with a normally closed but resiliently openable rubber septum position on the opposite side of its rubber flap from the engagement end of the respective members. The male member is provided with a blunt cannula which is fixed and a moveable carrier supporting the rubber septum. The female member is provided with an axially moveable support for the rubber flap and a fixed support for the rubber septum.

Abstract: A stackable container having excellent resistance to impact breakage includes (1) a plastic tank for containing liquids having at least one opening in its upper end and upper and lower abutments extending around sidewalls, (2) a top member engaged to the upper end of the tank having a downwardly facing abutting edge resting upon said upper abutment and (3) a bottom member engaged to the lower end of the tank having an upwardly facing abutting edge resting upon said lower abutment and having a plurality of downwardly extending legs. The tank has a generally rectangular configuration with a sump defined at one corner extending downwardly from the bottom and an internally raised area at another corner defining a depression forming an external ledge. Two tanks may be stacked in bottom-to-bottom relationship with the sump of one tank engaging the ledge of the other tank.

Abstract: Tooling for use in forming articles and a method for making same wherein the tooling includes a mold. The mold has a mold surface having an interior and an exterior. A plurality of metallic strands are positioned adjacent to the interior of the mold surface. The mold further includes at least one metallic heat transfer tube for containing a fluid cooling agent. One or more heat transfer rods can also be positioned in the mold. A layer of a plastic material is placed adjacent the interior of the mold surface. The plastic material surrounds the metallic strands and the metallic heat transfer tubes and rods. When heat is produced on the mold during a molding operation, the heat is transferred through the metallic strands and the heat exchange tubes and rods. The heat is dissipated by the cooling affect caused by the cooling fluid in the tubes.

Abstract: An apparatus for directing and regulating the flow of fluid from a conduit system. The apparatus includes a tubular housing for encasing a deflector body, the deflector body containing a cartridge having a plurality of spaced-apart, parallel, movable vanes. Each element of the assembly is integrally molded from a plastic material. The vanes of the cartridge are interconnected by a pair of diagonally disposed tie-bars which permit the vanes to move in unison relative thereto, and a detent system including the tie-bars for counteracting the memory of the integral connection between the tie-bars and the vanes thus holding the vanes in desired positions relative to the deflector body.
