    摘要： A method for blow down hydroforming sheet material includes hydraulically inflating a seal intermediate a pair of wall members and disposed between a platen and a table in circumscribing relationship with a cavity formed in the platen to seal the cavity and injecting gas into the cavity to urge conformance of the sheet material with a mold placed upon the table.

    摘要： A platen for applying pressure during hydroforming of polycarbonate and similar sheet material includes a flexible diaphragm for applying pressure in response to hydraulic fluid under pressure within a platen cavity and a diaphragm circumscribing sealing member for inhibiting seepage of hydraulic fluid and for preventing outward migration of the material of the diaphragm during a hydroforming operation. The junction between the sealing member and the diaphragm is conforming and void free to prevent hydraulic fluid flow therebetween. To help contain the hydraulic fluid within the platen cavity, a circumscribing inwardly extending foot of the diaphragm provides a mechanical and dynamic seal against an adjacent surface of the platen cavity.

    摘要： A material handling apparatus including a forklift assembly for attachment to a hanger bracket carried on the front end of an automotive vehicle of the type which may travel over roads and highways. The forklift assembly and hanger bracket are both especially configured for demountable attachment of the forklift assembly, and to allow pivotal movement thereof relative to the hanger bracket so that tilting of the forklift assembly may be accomplished without the vehicle's close proximity restricting such movements.

    摘要翻译： 用于在聚碳酸酯和类似片材的液压成形期间施加压力的压板包括柔性隔膜，用于响应于压力腔内的压力下的液压流体施加压力，以及用于抑制液压流体渗出并防止液压流体的向外迁移的膜片外接密封构件 在液压成型操作期间隔膜的材料。 密封构件和隔膜之间的接合部是一致且无空隙的，以防止液压流体在其间流动。 为了帮助容纳压板空腔内的液压流体，隔膜的向外延伸的脚提供了抵靠压板空腔的相邻表面的机械和动态密封。
