摘要:
A shock-absorbing innersole for use in footwear, which innersole comprises an innersole body composed of a substantially nondeformable elastomeric-type urethane cellular polymer, having a contoured molded heel and arch section and a substantially flat sheet containing a ball and toe section, the innersole having one or more shock-absorbing inserts in the innersole positioned in the heel, ball or both areas of the innersole, the insert composed of a solid elastomeric polymer which has greater shock-absorbing properties and greater surface tack than the elastomeric urethane of the innersole body.
摘要:
A shoe-innersole material for use in providing cushioning and support in footwear, and a method of manufacturing the shoe-innersole material, the shoe innersole comprising a heel and an arch section composed of a molded, elastomeric polyurethane foam material of low compression set, the heel and arch sections directly bonded in the molding process to a full-sole material composed either of foam or a solid, flexible sheet material.
摘要:
An inexpensive, cellular plastic mold and method of preparation, wherein the plastic mold comprises male and female mold elements which define a mold cavity therebetween, each of the elements comprising a rigid thermoplastic foam or cellular board material having a smooth, integral, solid layer of a plastic material forming the facing surface of the mold cavity and a relatively thick, solid, supporting layer of a plastic material forming the back surface of the mold elements.

A pressure reduction apparatus is disclosed. Air at high pressure and temperature may be drawn from a source such as a bleed valve of a gas turbine engine that supplies the air to an airplane interior. The air is passed to a pressure reduction vessel. The vessel has sufficient volume such that the high pressure air, upon entering the vessel, will reduce in temperature and pressure. The pressure reduction apparatus allows the air to depressurize and drop in temperature to near ambient conditions. Upon exiting the pressure reduction apparatus, the air is at a temperature and pressure sufficient to allow the air to be sampled and analyzed by conventional equipment used for testing for airborne impurities such as semivolatile compounds ad particulates.

Sweetening of hydrogen-sulfide polluted liquids such as water and those whose viscosity is not substantially greater, is accomplished in upright tanks of constant cross-section, which are substantially conventional except for man-way provisions which permit clean-out and replacement of contents. Each tank, which has a liquid inlet provision near its bottom, is divided by its contents into three sections: a lowermost turbulence-eliminating section, an intermediate reacting section, and an uppermost tranquil purified storage section. Increase in capacity to fill a constant demand is attained by simply increasing the depth of the reacting section, to the lessening of the purified reserve.
