摘要： Particulate inorganic pore material, e.g., controlled pore glass (CPG) embedded porous synthetic resin membrane is prepared by mixing inorganic pore material and an aqueous resin, preferably polytetrafluoroethylene (PTFE), aqueous dispersion to form a paste-like mass, heating the mass at a temperature between 50 to 70° C., and forming the mass into a sheet by calendering. The sheet is then sintered to produce a rigid porous sheet. The membrane may be functionalized, as by silanization. The membrane is useful for the same purposes as controlled pore glass or functionalized controlled pore glass.

摘要： Pre-inked impression members for hand stamps are made from a gel or premix of thermoplastic resin particles and liquid ink with use of a disposable molding device comprising a matrix board that is recessed in its molding area with cavities to form inked indicia of the impression members and has a peripheral surface area to which is adhered fluid-tight, and entirely about the molding area, an upright rigid wall means comprising a structure of fiberboard, wood, hard resin or other suitable material shaped to a height corresponding to the desired thickness of the impression members. As another feature, during the heating for curing of a layer of premix formed over the molding area of a matrix board, the layer of premix is confined in place by a covering means, applied over it and held under pressure, which comprises, together preferably with overlaid pliable ink-absorbent material, e.g., plural cut sheets of newspaper, a pliable parting sheet, such for example as a sheet of emery cloth, coated on a side thereof contacting the layer of premix with a substantially resin-impermeable yet ink-permeable layer of fine particles nonadherent to the resin of said premix.
摘要翻译：用于手印的预打印印模构件由热塑性树脂颗粒和液体油墨的凝胶或预混物制成，其使用一次性模制装置，该模制装置包括在其模制区域中凹入空腔的基质板，以形成印模构件的墨迹标记并且具有流体密封且完全围绕成型区域的周边表面区域，直立的刚性壁装置，其包括纤维板，木材，硬质树脂或其它合适的材料的结构，其被成形为相当于所需厚度的印象成员。作为另一个特征，在用于固化在基质板的成型区域上形成的预混物层的加热期间，预混物层通过覆盖装置被限制在适当位置，施加在其上并保持在压力下，其优选包括具有覆盖的柔软的吸墨材料，例如多个切割的报纸，一个柔韧的分页片，例如一块金刚砂布，涂覆在与预混物层接触的一侧，基本上不透水的，与所述预混物的树脂非粘附的细颗粒的可渗透层。
