The steps are performed in plural independent units in each of which one step is executed, and the mold and the substrate are paired with each other by the assembling jig and conveyed between the units in a range of from the alignment step to the separation step. An imprinting apparatus includes an alignment unit which performs the alignment step, a press unit performing the press step, and a separation unit performing the separation step, wherein conveyance devices are provided to convey the mold and substrate between units.

    Abstract: A molding apparatus includes an extruder to provide a molten composite material, and an adjustable extension barrel coupled to the extruder to receive the molten composite material. The adjustable extension barrel has a drop point to output the molten composite material. The adjustable extension barrel is moveable in a first direction between an extended position and a retracted position to change position of the drop point. A structure is movable in a second direction that is perpendicular to the first direction. A lower mold is carried by the structure and is positioned to receive the molten composite material from the drop point of the adjustable extension barrel. A press includes an upper mold and is operated to press the upper mold against the lower mold to form a molded article.

  • Publication number: 20150090923
    Abstract: The invention includes a tablet made from a coagulant that will improve the settling of suspended solids in an aqueous media such as wastewater, recycled water, potable water, storm water, swimming pool water, spa water, boiler water, cooling tower water and industrial process water. The agent is a tablet containing at least one salt from the aluminum sulfate family in a mixture of organic and inorganic binders. The mixed material is especially adapted to lend itself to high speed molding operations. Such agent, when in molded form, provides controlled dissolution in an aqueous media, exhibits strength and non-chipping characteristics which is a benefit in shipping and handling and is free from dusting, flaking or other deteriorative factors. In its tablet form, this agent can be used in combination with a holding apparatus having slotted opening zones.

    Abstract: The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating a flowable solid of a self-solidifying cleaning composition. For a self-solidifying cleaning composition, pressing and/or vibrating a flowable solid determines the shape and density of the solid but is not required for forming a solid. The method can employ a concrete block machine for pressing and/or vibrating. The present invention also relates to a solid cleaning composition made by the method and to solid cleaning compositions including particles bound together by a binding agent.
