摘要： Molded boot and shoe heels are made by injecting a foamable plastics molding material into a heel mold and thereafter injecting a pressurized gaseous fluid into the heel body after it has formed an outer skin against the mold inner surfaces but before it has fully set in order to displace and compress the foaming material and form within the heel at the point of injection at least one enclosed hollow chamber which provides a different degree of resilience to heel strike forces at the location of the chamber. A plurality of closely adjacent chambers may be provided to obtain the same effect, particularly when the heel is shallow. A preformed member may be molded into the heel to form the heel outer surface and ensure a minimum heel wall thickness at this location. The heel may be molded integrally with a sole part. The enclosed chamber may be vented to the ambient atmosphere or it may be sealed. The chamber may be at least partly filled with a material of resilience different from that of the material from which the heel is molded. In another molded heel structure a chamber is formed in the heel by a preformed hollow member attached to the underside of the boot or shoe upper, the member being incorporated into the shoe heel by the molding operation. An insole mounted inside the upper has a plug of lower resilience material that fits into the chamber formed by the hollow element to determine the resilience to heel strike.

摘要： A method for producing a foam-containing structure. In a first embodiment, a defoamer is applied to the inner surface of an impermeable carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer on the inner surface. The foamed resin and liquid resin layer are cured to produce a foamed resin inner core and a solid resin outer layer. In a second embodiment, a permeable carrier is covered with an impermeable release material. A defoamer is applied to the carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer impregnating the carrier. The foamed resin and liquid resin layer are cured to produce a foamed resin inner core, the carrier as a facer material, and a solid resin layer impregnating the carrier. In a third embodiment, a defoamer and a catalyst are applied to a permeable carrier. A foamed resin is introduced inside the carrier and contacts the defoamer to form a liquid resin layer impregnating the carrier. At least a portion of the liquid resin layer contacts the catalyst and cures into a solid resin layer. The foamed resin and any uncured portion of the liquid resin layer are cured to produce a foamed resin inner core, the carrier as a facer material, and a solid resin layer impregnating the carrier.

摘要： A brush with a one-piece plastic brush body produced by injection moulding comprises a head covered with bristles and a dimensionally stable handle with a larger cross-section than the head, the brush body being made from an elastomer mixed with a foaming agent and the plastic is foamed in an area of the handle and is solid in the area of the head. The brush is produced by injection moulding in a two-part mould. An elastomer and a foaming agent are mixed during moulding. The mould cross-section for forming the head is smaller than the mould cross section for forming the handle with the elastomer being only foamed in the area of the handle.

摘要： A variable pitch fan for a helicopter equipped with a NOTAR.RTM. mechanical antitorque directional control system comprises a plurality of blade assemblies. Each blade assembly includes a blade portion, which is molded from a blended material which includes fiber reinforced polypropylene. A key to the invention is the use of long fibers, having a length of at least approximately one-half inch, for reinforcement, the long fibers providing for about twice the pull-out strength of short or chopped fibers. Another key aspect of the invention is the use of a blowing agent in the blended material, which serves to reduce weight and warpage by creating a foamed structure having a variable density, the structure retaining considerable strength because of the fiber reinforcement. The blade portion is molded about a spar which has holes therethrough, the holes providing a mechanical interlock between the blade and the spar.

摘要： A method for making a novel, relatively low-cost loudspeaker cone assembly with an integral suspension rim. The method is for making a cone assembly wherein a cone body having an outer free edge is placed within an open female mold having an annular channel configured to form the suspension rim with the free edge of the cone exposed to the channel. A predetermined quantity of liquid plastic is deposited into the channel of the open mold. Next, the mold is substantially closed by a male die to seal the cone body adjacent its outer free edge. The liquid plastic is then cured under specific pressure and temperature conditions, over a selected interval, so that the resulting annular suspension rim is integrally impregnated into the free outer edge of the cone body and forms high density closed-cell outer skin surfaces in an integral sandwich construction with a low density closed-cell inner core, thereby providing improved flexibility, strength and durability. The outer skin surfaces of the suspension rim so produced have a rubber-like surface texture and protect the suspension rim from the adverse effects of ultraviolet radiation and other environmental conditions.

摘要： A method of making thermal insulating products comprising porous, lightweight, high temperature resistant inorganic particles in a polyimide foam matrix and the product thereof. A polyimide precursor powdered is mixed with about equal weight of flake-like porous inorganic particles to substantially uniformly coat the particles with powder. The mixture is placed in a mold and compressed slightly. The assembly is heated to the foaming temperature of the polyimide precursor for a period suitable to produce uniform foaming. Then the temperature is raised to the curing and crosslinking temperature of the precursor for a time period sufficient to produce complete cure. A high temperature and flame resistant, light weight, highly insulating product results. If desired, protective sheets of material may be bonded to selected product surfaces during or after the molding operation.

摘要： A first reaction mixture, prepared from (a) isocyanates with isocyanate contents of from 5 to 50% and (b) compounds with molecular weights of from 32 to 10,000 which contain at least two isocyanate-reactive hydrogen atoms, in an equivalent ratio of component "a" to component "b" of 0.8:1 to 5:1, from 0.1 to 20% of a blowing agent and, optionally, other known additives, is introduced into the rigid cavity of a closed mold. After this mixture has become resistant to permeation, but is still compressible, a second reaction mixture, either the same or different from the first reaction mixture, prepared from (c) isocyanates having isocyanate contents of from 5 to 50% and (d) compounds with molecular weights of from 32 to 10,000 which contain at least two isocyanate-reactive hydrogen atoms, in an equivalent ratio of component "c" to component "d" of from 0.8:1 to 5:1, specific internal mold release agents and optionally blowing agents and other additives, is introduced into the mold, such that it surrounds the first mixture and compresses it. A third, optional, reaction mixture, the same as or different from the second mixture, may also be employed in a manner similar to the introduction of the second mixture. The final composite plastic part releases smoothly from the mold.
