  • Patent number: 10279558
    Abstract: A method for producing a skin-covered foamed molded article including blow-molding a parison in a mold cavity to form a skin consisting of a hollow molded body, in which the parison is in a softened state by extruding a molten thermoplastic resin, filling expanded beads in the hollow molded body, and heating and fusion bonding the beads by supplying steam via a steam supply pipe inserted into the hollow molded body. The parison is in contact with a protruding portion, formed by protrusion from an inner surface of the mold cavity to an inside of the cavity, forming a recessed portion having a shape corresponding to the protruding portion in the inward direction of the hollow molded body. A steam hole is formed in the recessed portion, a steam supply pipe is inserted into the body, and the expanded beads are heated and fusion bonded by supplying steam.

  • Patent number: 9168673
    Abstract: A device for removing concrete debris from passages within modular blocks is disclosed. The device includes nozzles mounted to a plate at locations corresponding to the passages on the modular blocks. An actuator is secured to the block molding machine, supports the plate, and moves the plate from a retracted position to an extended position in close proximity to the conveyor. The nozzles are operatively connected to a source of compressed air and are arranged to enter within the passages of the modular block when the plate moves to the extended position. A control system directs operation of the device such that when a modular block reaches a predetermined location on the conveyor, the actuator moves the mounting plate to the extended position causing the nozzles to enter within the passages of the modular block and emit jets of compressed air to remove concrete debris from within the passages.

The precursor web can be cast directly onto the forming structure, or it can be re-heated by re-heat means to elevate its temperature sufficiently to permit vacuum formation.

  • Patent number: 6706236
    Abstract: To make holes in ceramic green sheets that are needed to create feedthroughs, it is proposed to make the holes by using a gas that is under a higher pressure than atmospheric pressure and that is expelled in a pulsed manner from a pressure vessel and thereby acts on a principal surface of a ceramic green sheet, at at least one location at which a hole is to be made, in such a way that material is shot out of the ceramic green sheet at that location. This eliminates the disadvantages associated with the use of punches to punch holes.

  • Publication number: 20030091843
    Abstract: The invention relates to a single- or multilayer, transparent, amorphous film which comprises at least one crystallizable thermoplastic as main constituent, in particular a polyester, and also comprises at least one hydrolysis stabilizer. The hydrolysis stabilizer is preferably a phenolic compound, an oxazoline, and/or a monomeric or polymeric carbodiimide, where appropriate combined with an organic phosphite. It is preferably added in the form of a masterbatch. On exposure to moisture and heat it shows practically no embrittlement and retains its tensile stress at break. The film may have been rendered UV-resistant, or flame-retardant, or one side or on both sides have been coated, or be sealable, and/or have been corona- or flame-treated. It is generally produced by extrusion or coextrusion, the hydrolysis stabilizer being added in the form of a predried or precrystallized masterbatch. The film can be shaped particularly effectively by thermoforming.

  • Patent number: 6451240
    Abstract: A microneedle array is manufactured using a mold preparation procedure that begins by placing an optical mask over a layer of PMMA material, exposing the PMMA material to x-rays, then developing using a photoresist process. The remaining PMMA material is then electroplated with metal. Once the metal has reached an appropriate thickness, it is detached to become a metal mold that is used in a microembossing procedure, in which the metal mold is pressed against a heated layer of plastic material. Once the mold is pressed down to its proper distance, the plastic material is cooled until solidified, and the mold is then detached, thereby leaving behind an array of microneedles.
