  • Patent number: 6706231
    Abstract: Method for compression molding plastic closures having a peripheral skirt with an internal thread includes a first mold assembly having a male mold core and a second mold assembly having a female mold cavity. At least one of the first and second mold assemblies is moved relative to the other to bring the male mold core into the female mold cavity for compression molding a closure, and then is moved to open the cavity such that the closure is retained on the male mold core. The male mold core is rotated relative to the first mold assembly to unthread the core from within the closure, and thereby strip the closure from the core, without stretching the closure skirt over the core or wiping the internal thread over the external surface of the mold core.

  • 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.

  • Patent number: 6685857
    Abstract: A method and apparatus for repairing or refurbishing thermoplastic drums, by which a damaged drum, or at least a damaged portion thereof, is heated until it reaches a softened state and is then drawn over a template, or mold, having the substantially the same shape and size of an undamaged drum. The drum is allowed to cool sufficiently to return to its hardened state, whereby it substantially assumes the shape of the template. The refurbished drum is then removed from the template and is essentially ready to be used again.

  • Patent number: 6676862
    Abstract: A method and apparatus for efficiently forming individual building units is provided, generally includes providing a plurality of molds, each capable of simultaneously forming a plurality of building units. Batches of cementitious slurry are individually mixed in order to control the density of each building unit formed. The ingredients are individually measured and combined into the mixing device. The cementitious slurry is then conveyed or transported and poured into one of the molds. The method provides the ability to control the amount of cementitious slurry in each batch in order to control to the extent possible the quantity of cementitious slurry poured into each mold and the ability to precisely control the dimensions of each building unit produced.

  • Patent number: 6652791
    Abstract: The invention relates to a method of manufacturing a reinforced oblong concrete product for longitudinal load-bearing purposes, in particular a driving pile. According to the present invention reinforcing fibers are used to prevent break-up of the concrete due to radial forces which occur during driving, and the concrete composition is provided with said reinforcing fibers before the concrete composition is applied to the reinforcing wire. This method reduces the amount of heavy labour and cost. The invention also relates to a driving pile comprising reinforcing fibers.

  • Patent number: 6610224
    Abstract: A decorative aggregate-containing cementitious slurry having decorative aggregate and cementitious matrix composition forms a monolithic structure when effectively applied to a freshly poured cementitious base and simultaneously cured therewith. The slurry and the base are cured for a time sufficient for producing the monolithic structure with a decorative aggregate-containing cementitious surface. The slurry produces a decorative aggregate-containing cementitious layer having a cured thickness effective for permanently securing the decorative aggregate therein with a portion of the decorative aggregate exposed. Various decorative surfaces are produced without requiring expensive hand broadcasting of the decorative aggregate, and without expensive surface grinding. Dry components of the slurry are decorative aggregate and decorative cementitious matrix blend.

  • Patent number: 6572811
    Abstract: A method is provided for rapidly forming a cementitious panel. A cementitious mixture is introduced into a mold configured to provide the desired surface appearance and profile of the cementitious panel. The cementitious mixture is then subject to an accelerated curing process by applying microwave energy to the cementitious mixture for a predetermined time period. After a relatively short resting or cooling period, the resulting cementitious panel is ready to be removed from the mold.

  • Patent number: 6558597
    Abstract: A process for forming an end cap in an extruded ceramic tube. An end cap forming cavity of an end cap forming die is positioned so that, when the body of the end cap forming die is situated against an extrusion die, ceramic material is able to be forced into the end cap forming cavity, through a passageway communicating between the end cap forming cavity and a backfill reservoir, and into the backfill reservoir. A plunger projects into the backfill reservoir to force the ceramic material from the backfill reservoir back through the passageway and into the end cap forming cavity to compact the ceramic material so that the ceramic material within the end cap will be provided with a substantially uniform density.

  • Patent number: 6551535
    Abstract: A high throughput, automated process for coating ceramic monoliths used as catalytic converters that overcomes problems with coating monoliths individually in a mold. The monoliths are provided with end caps to cover the open functional ends, then loaded serially into an inlet channel leading to an extrusion chamber. As each monolith is pushed into the channel, one monolith enters the extrusion chamber, and the monolith just coated in the extrusion chamber is made to exit onto a finished part conveyor. Thereafter, the end caps are removed and cleaned for reuse on new monoliths yet to be coated.
