Treatment Of Material By Vibrating, Jarring, Or Agitating During Shaping Patents (Class 264/69)
  • Patent number: 4036922
    Abstract: Hydraulic cement or the like is poured into a closed mould under a reduced pressure condition to a level slightly higher than a predetermined level. Coarse aggregate and steel rods are prepacked in the mould. After pouring the pressure in the mould is increased to atmospheric pressure or a higher pressure to force the hydraulic cement above the predetermined level back into the space below the level thus compacting the poured in hydraulic cement. A cushion device is provided for the pouring device. An overflow tank is connected to the mould to observe the level of the poured cement. The pressure in the overflow tank is also decreased during pouring and increased after pouring.

  • Patent number: 4032383
    Abstract: A method and apparatus are described for the making of a three dimensional filament reinforced foam insulation member. Generally parallel arrays of vertically stacked fabric or cloth having filaments running in an X-Y axis are reinforced by third axis Z directional filaments pre-cut to a desired length and inserted down through openings referred to as vertical columns hereinafter through the said array. The Z filaments are air directed through the stack of open weave. After the formation of the filament reinforced weave the assembly is impregnated with foam to form a unitary member. The apparatus to form the article and carry out the method above consists of a conveyor carrying stacked open weave fabric through an open ended enclosure wherein there are provided first vertical tubes and second vertical tubes. The second vertical tubes are injected into the stack or array of open weave. The first vertical tubes are telescopically inserted into the tops of the said second vertical tubes.

  • Patent number: 4022859
    Abstract: A method of producing shaped concrete blocks for hydraulics, such blocks having two spaced arms formed at right angles to each other and spaced from each other and a web interconnecting the centers of said arms, wherein said block is formed by concreting in a dismountable shuttering with the arms located horizontally and the web vertically, it being possible to use a shuttering having a stationary, lower shuttering part which has a horizontal longitudinal axis for forming substantially half of one arm of the block and two shuttering parts separatable from the formed block by lateral movement.

  • Patent number: 4017570
    Abstract: The preparation of three dimensional skeletal structures using the step of deforming rounded beads to form a mold or matrix is described. A filler material is introduced and then rigidified to form the skeletal structure. The deformable beads are composed of materials which deform upon compression or expansion due to pressure from adjacent beads and included, for instance, metals, waxes, salts, polymers, and ceramic compositions in their plasticly deformable states. The filler material which rigidifies to form the skeletal structure can be composed of solidifiable materials such as metals, polymers, or ceramic compositions. The solid material volume of the skeletal structure so formed upon removal of the beads is between about 2% to 20% of a corresponding volume of a non-skeletal solid material. The corresponding porosities representing the interconnected void volumes are between about 80% and 98% of a corresponding volume of a non-skeletal solid material.

  • Patent number: 4003665
    Abstract: A stylus is assembled from a plastic tip having an axial bore and an ink tube in said bore centered therein and welded thereto. Ultrasonic welding is used for softening and partially melting the tip. On switching off the ultrasonic energy source, the molten portion of the tip hardens and provides a strong bond between the tip and the ink tube.

  • Patent number: 4001365
    Abstract: A load-bearing wall panel is fabricated by disposing an assembly of spaced-apart and aligned, hollow-cored bricks onto a molding base containing melted paraffin. Contact of the cooler bricks with the melted paraffin forms a thin skin of solidified paraffin on the brick bottom portions and forces melted paraffin within the joints forming therein a double-convex configuration of solidified paraffin, thereby water-proof sealing the brick bottom portions and joints preparatory to mortar introduction. After curing of the mortar introduced in the joints and cores, the resulting wall panel has load-bearing capacity and unique, double-concave mortar joints that are smooth, water-proof and weather-proof.

  • Patent number: 3972758
    Abstract: The invention refers to a method of forming over the edge of a plastic jacket against a workpiece using vibratory energy. Specifically, the workpiece and jacket are disposed on a resiliently mounted anvil. As the jacket forms over and shortens its axial length, the anvil is displaced to provide a decreasing engagement force between the jacket and the horn of the vibratory apparatus. As a result, the jacket is free of scars or distortions in the region of forming.

  • Patent number: 3966520
    Abstract: Two telescopingly engaging tubular thermoplastic workpieces are welded together by ultrasonic vibratory energy applied radially. The workpieces are disposed on a mandrel for preventing distorting or collapsing of the opening in the inner workpiece. A tapered hole in the ultrasonic tool in combination with an axial force upon the workpiece provides a radially compressive force upon the outer workpiece to cause intimate contact between the softened workpiece surfaces during welding.

  • Patent number: 3962007
    Abstract: Slide-fastener stringers are made by extruding continuous strands of synthetic resin in a form having a plurality of cavities open on one side and defining the coupling head, shank and connecting portion of a multiplicity of coupling members which together form a coupling element adapted to be mounted along the edge of a support tape. An embossing tool is thrust into the connecting members and/or the shanks of the coupling members so as to plastically deform the thermoplastic material and produce humps along the surfaces of the coupling element which are thermally bonded to the support tape.

  • Patent number: 3950465
    Abstract: A pipe of concrete, cement mortar or other cementitious material is formed by an integrally cast cementitious mass which is reinforced with a glass fibre strand or roving forming a substantially helical winding extending around the pipe and incorporated in the cement matrix of the cementitious mass. Preferably there are two windings, one incorporated in the outer periphery of the mass and the other incorporated in the inner periphery of the mass. The pipe is preferably made by a centrifugal casting operation in which a centrifugal casting mould is rotated and the glass fibre strand or roving is fed from a feeding device within the mould and is caused to adhere to the internal peripheral face of the mould and then the feeding device is moved axially along the mould as the mould rotates so that the winding is formed from the roving around the internal peripheral face of the mould.
