  • Patent number: 5310257
    Abstract: A clamping fixture slides between a pair of guide rails and includes a pressure plate between the guide rails. Lock plates with internal openings for receiving the guide rails are held captive on the pressure plate. An operating bar with stepped ends, one adjacent each locking plate, is deflected by a cam mechanism to incline the lock plates relative to the guide rails, thus wedging the lock plates to prevent further sliding along the guide rails. Return springs are provided to urge the lock plates to an unlocked position when pressure on the operating bar is released. A mixing apparatus using the clamping fixture is also disclosed.

  • Patent number: 5230911
    Abstract: The present invention relates to an improved clamping mechanism for use in injection molding machines and similar pieces of equipment where it is desired to apply a clamping force to particular components. The clamping mechanism of the present invention employs at least one spaced apart brake plate mounted to one component and a braking unit for engaging the brake plates. The braking unit has at least one pair of brake pad linings surrounding the brake plates and at least one piston-cylinder unit for causing frictional engagement between the respective brake pad linings and the brake plate(s). When the brake pad linings grip the brake plate(s), the braking unit becomes locked to the components to which the brake plate(s) are attached. The clamping mechanism of the present invention may be employed on simple injection molding machines as well as TANDEM.RTM. injection molding machines.

  • Patent number: 5167750
    Abstract: A heat sealing machine for imprinting garments and the like has a base (10) carrying a lower, horizontal platen (18) above which an upper heated platen may swing from an open, generally vertical position at the rear of the lower platen to a closed position superimposing the lower platen with the upper platen (24) being carried by lever arm (28) pivoted at (26) adjacent its rear end with over-center locking and force multiplying linkage (82, 84 and 96, 98) operatively connected by actuating links (90, 92) to a relatively movable handle mechanism (70) whereby as the handle is swung downwardly to close the upper platen, during the last increments of such closure, relative downward movement of the handle with respect to the platen causes the over-center and force multiplying linkage (82, 84 and 96, 98) to squeeze the upper platen against the lower platen. Threaded member (62) is provided for adjusting the pressure imposed by the upper platen.

  • Patent number: 5160750
    Abstract: A clamp assembly for selectively friction clamping a member with respect to a column includes inner and outer threaded portions positioned concentrically around the column and within a housing attached to the member. The inner and outer threaded portions are threaded together to transfer force therebetween. A sealed chamber between the inner and outer threaded portions is selectively pressurized to cause an inner surface on the inner threaded portion to displace inwardly onto an outer surface of the column and the outer threaded portion displacing outwardly to provide frictional resistance to longitudinal movement of the member with respect to the column. The inner thread portion and the outer thread portion have a thread pitch difference to substantially compensate for strain deformation occurring thereupon.

    Abstract: A system for baling strands of material wherein a predetermined quantity of strands of material is compressed into a bale of strands of material having a density of at least about 14 pounds per cubic foot and having a substantial portion of the bale unmatted, the system being particularly useful for baling easter grass. The system includes a baler wherein the strands of material are compressed in a substantially enclosed portion of the baler to form the bale of material. In the system, a predetermined weight comprising a portion of the total desired weight of a bale of material is compressed, and additional portions are added and compressed until the total desired weight has been compressed into a bale of material.

  • Patent number: 5035606
    Abstract: A high tonnage reaction injection molding (RIM) press has fixed and movable platens for clamping a composite mold therebetween at a closed mold position. A plurality of high pressure hydraulic cylinders are mounted on a carrier for the movable platen, and a locking mechanism having a plurality of incrementally spaced locking positions is effective to lock the carrier selectively at said positions. A pair of low power hydraulic piston-cylinder assemblies connected with the carrier adjacent to its opposite ends move the carrier and movable platen to the closed position. Short stroke connecting rods operated by the high pressure cylinders are forced independently of each other into high tonnage engagement with the movable platen at a plurality of locations within the area of the composite mold to clamp the latter between the platens and positively seal its junctures, whereupon a RIM mix head injects the high pressure reactive chemicals into the sealed mold.

  • Patent number: 4990081
    Abstract: An apparatus for shaping, by compacting, carbonaceous blocks formed by a carbonaceous paste based on a carbonaceous aggregate such as coke, anthracite or graphite, and an organic cokable binder such as tar and optional additives. The carbonaceous paste is introduced into a mould in which some of the walls are displaceable with respect to their initial position and there are successively applied to said paste at least one stress .sigma.n along an axis An, then at least one stress .sigma.n+1 along an axis An+1 which is not coincident with the axis An, then at least one stress .sigma.n+2 along an axis An+2 which is not coincident with the axis An+1, and so forth, repetitively, each stress .sigma.(i) being applied after at least partial suppression of the stress .sigma.(i-1). Use of the apparatus substantially enhances compactness of the carbonaceous blocks.
