摘要： A method and apparatus for molding foamed materials for use as carpet underpadding is disclosed. In one aspect, the process and apparatus involves pulling a sheet of a foamed material through a first set of pull rolls at a first pull rate followed by heating the foamed material in order to decompose blowing agent present in the sheet thereby causing the sheet to expand or thicken. The heated sheet is then pulled through a second set of pull rolls which pull the heated sheet at a faster rate than the first pull rate in order to stretch the expanded sheet so that it returns to its original thickness. The surface of one of the rolls of the second set is provided with dimples or indentations uniformly spread on the surface thereof for producing protrusions on one side of the heated sheet. In one form of the apparatus, the roller with the dimples is cooled while the molded sheet is retained against this roller after formation of the dimples in order to provide cooling for the former to allow the protrusions to set properly. The molded sheet is further cooled as it is run along cooled rolls after which it is trimmed and collected.

摘要： A degradable polymer network obtained by adding from 0.2 to 10 parts by weight of a foaming agent to 100 parts by weight of a polylactic acid-base resin composition comprising from 80 to 100% by weight of polylactic acid or a lactic acid-hydroxycarboxylic acid copolymer and from 0 to 20% by weight of a plasticizer, conducting melt-foaming extrusion of resulting mixture, and opening the foam cells in the extrudate. The high polymer network is characterized in suitable flexibility and hydrolyzability and thus useful as a material for absorbing oils and body fluids, screens for sunlight, heat-insulating materials, filter media and packaging materials; and does not accumulate as industrial wastes because of hydrolyzability in the natural environment, even though abandoned after use.

摘要： A method of manufacturing polyimide foam filled structures such as honeycomb panels. A polyimide foam precursor is prepared in powder form. A layer of the powder is heated and foamed at the resin condensation temperature and pre-cured to an easily handleable, stiff and inflexible state. A multi-cell, thin-walled structure having open cells along a surface is pressed into and through the foam sheet so that foam pieces fill the cells. The foam is then heated to a final cure temperature at which the foam becomes stable, resilient and flexible. Face sheets may be bonded to the structure to retain the foam pieces in the cells. If desired, the walls of the structure that contact the foam may be coated with an adhesive, such as a liquid polyimide adhesive resin precursor, so that the foam will be bonded to the cell walls when the liquid resin precursor is cured as a necessary result of the final foam cure conditions.

摘要： A process for rapidly cooling porous foam material to prevent oxidation or autoignition of said foam. The process includes a first cooling step wherein cooled ambient air is drawn through the foam block thereby cooling, dehumidifying and removing fumes from said block before being vented, a second cooling step wherein cooled ambient air is drawn through the block for further cooling thereof, with sublimates in the block being condensed and redeposited within the block, and a third cooling step wherein ambient air is drawn through the material so as to remove remaining fumes, heat and moisture therefrom. The process of the present invention advantageously utilizes a foam formulation which includes an increased percentage of water for providing adequate foaming of the material while minimizing or obviating the need for including toxic auxiliary blowing agents in the formulation. In addition, the formulation may also have a lower TDI index as compared to formulations utilized in conventional cooling methods because TDI is condensed and recycled back into the foam. An apparatus especially configured and adapted for practicing the process of the present invention is also disclosed.
摘要翻译：一种用于快速冷却多孔泡沫材料以防止所述泡沫的氧化或自燃的方法。该方法包括第一冷却步骤，其中冷却的环境空气被抽吸通过泡沫块，从而在排气之前从所述块排出冷却，除湿和除去烟雾;第二冷却步骤，其中将冷却的环境空气通过块进行进一步冷却，块体中的升华物被冷凝并重新沉积在块内，以及第三冷却步骤，其中环境空气被抽吸通过材料，以便从中除去剩余的烟气，热量和水分。本发明的方法有利地利用泡沫制剂，其包括增加百分比的水以提供材料的充分发泡，同时最小化或消除在制剂中包含毒性辅助发泡剂的需要。此外，与常规冷却方法中使用的制剂相比，制剂也可以具有较低的TDI指数，因为TDI被冷凝并循环回到泡沫中。还公开了一种特别配置和适于实施本发明的方法的装置。

摘要： A transition layer for an implant to be placed in the human body. The implant has a core, and the transition surface surrounds the core. The transition layer is an open celled foam with cut surfaces. An adhesive adheres one surface to the core, and penetrates the transition layer a limited distance so as to leave over the entire surface, microstructures of cell fragments providing for tissue attachment without formation of a firm encapsulation.
