Abstract: An apparatus and method for manufacturing articles made of polyurethane that includes a mold assembly in communication with a mix chamber. The mix chamber is positioned below the mold assembly. The mix chamber includes a propeller for mixing the liquid polyurethane chemicals. The mix chamber further includes a pneumatically actuated bladder that causes the mixed chemicals to move from the mix chamber to the mold assembly. The chemicals expand to take on the shape of the mold. The method of the present invention comprises the steps of: (a) selecting polyurethane chemicals having certain specific weights; (b) placing said chemicals in a mix chamber wherein chemicals stratify according to their specific weights to prevent detrimental reaction among the chemicals until final mixing; and (c) allowing the chemicals to expand to form an article.

Abstract: A method and apparatus for forming articles made of polyurethane. The apparatus includes a polyol weigh tank, an isocyanate weigh tank, an additive tank and a mix tank enclosed by a vent chamber. The vent chamber is in communication with inlet and outlet pipes to move air and fumes from the interior of the vent chamber past a filter. The apparatus further includes a containment vessel also having inlet and outlet pipes for movement of air and fumes. The containment vessel is in communication with a pump for creating a vacuum in the vessel to reduce pressure in the interior of the vessel in which a mold is placed.

Abstract: A process for the production of an open cell polyurethane foam comprises the mixing of the following components at ambient temperatures in a mixing zone: a diisocyanate having a functionality of at least about 2.0, at least one hydrogen donor, at least one surfactant which is effective in forming an open cell polyurethane foam, at least one catalyst, and a blowing agent comprising a gas having a boiling point below approximately -100.degree. F. at atmospheric pressure which preferably comprises carbon dioxide. In addition, the mixture may also optionally contain water. The mixture is subjected to a pressure in said mixing zone which is sufficient to maintain the blowing agent in the liquid state at ambient temperatures. After mixing, the mixture is ejected from the mixing zone to atmospheric pressure, thereby completely and instantaneously vaporizing the blowing agent to provide expansion of the mixture. The resultant foam is then cured at ambient temperatures.

Abstract: A supersonic wing in turning the airstream downward to generate increased pressure on its underside also increases the air density. The energy of this compression field is normally diverted away from the wing downward towards the ground in the supersonic wave system, coalescing into a strong shock wave which dissipates most of this energy into heat, with a small residual reaching the ground and causing the sonic boom. My copending application No. 342,151, filed Mar. 16, 1973, disclosed the use of an expanding jet under a concave downward wing to transform this compression energy into vorticity. The present continuation-in-part application provides a wing section which concentrates most of the concave downward curvature of the wing underside in a short interaction region to generate the compression near its leading edge, corresponding to the short expansion region of the underexpanded jet.
