A process of laminating textile fabrics to opposite sides of polyurethane foam in which the lamination is effected by flame bonding under such conditions that the temperature to which the foam is raised at one side is different from that to which it is raised at the other side.

A method and apparatus for simultaneously generating and pumping foam. As air is being pumped, foam solution is transmitted through a number of bores formed in the pump's pumping members, whereupon foam is generated when the solution emerges from the bores and is discharged at the pump's outlet. Additionally the pumping members are designed to meter, through a plurality of inlet ports, amounts of different chemicals of foam solution into the pump.

A wet foam type gas scrubber for cleaning industrial gases and the like comprising foam generating means including a chamber having an inlet for gas and an outlet for foam. Grid means is provided in said chamber between said inlet and outlet and extending transverse to the gas flow therebetween for dividing the gas flow into a plurality of separate streams. Said grid means comprises a plurality of elongated strips interconnected to form a plurality of discrete flow passages and the strips have t...

This invention pertains to the field of foam compositions for application to the skin of a user. More specifically, the invention relates to foam compositions that act as a barrier to water, allergens, poisons, toxins and other skin irritants when applied to the skin of a user.

Disclosed is an absorbent foam that exhibits desirable softness and flexibility properties yet is highly absorbent. In one embodiment, the absorbent foam comprises a water-swellable, water-insoluble polymer wherein the absorbent foam exhibits a Free Swell value of at least about 10 grams of liquid per gram of absorbent foam and a Softness value that is less than about 30 grams of force per gram per square meter of absorbent foam. In a second embodiment, the absorbent foam has an average cell siz...

This foam dispenser includes a flexible container for foamable liquid, having a discharge opening at the upper end. A porous member is housed in the discharge opening and a conduit communicating with said porous member extends downwardly into the interior of the container. A flow directing valve system within the conduit determines the path of air and liquid through the conduit and the porous member during manual pressurization and depressurization of the container. The foamable liquid and air a...

A foam fractionator which can create a vortex is utilized to remove proteins from an aquatic environment by skimming. The vortex is created by a propeller arrangement located at the bottom of an internal chamber, centrally located within a main reaction chamber. Air sucked from the atmosphere by the vortex passes down through a central chamber and is dispensed outwardly into the main chamber where air bubbles form and rise to the surface. The air bubbles attract protein deposits which stick ther...

A golf bag holds golf clubs in a cavity in which a golf club receptacle structure is disposed. This receptacle structure has several versions. In one, an external, truncated, conical end portion at least partially extends outward from the cavity, with a plurality of openings which extend in a lengthwise direction through the receptacle structure, each opening sized to receive only one golf club. In another, the receptacle structure has a central portion and a marginal portion at a lower level th...

A finger-manipulated article (e.g., a pen) includes a foam grip. The foam preferably is made from a foamable polyurethane prepolymer and a filler, or a latex, or both. The preferred foam has a recovery rate of less than 5 cm per minute. The foam may include a surface coating on its outer surface.

A polyurethane or polyisocyanurate foam is derived from a mixture comprising a crude isocyanate component and a polyol component which contains all or some of the following products in a homogeneous mixture: polyols, catalysts, surfactants, water, flame-retardants, expanding agents, fillers, dyes and pigments, in which the expanding agents comprise a pentane component associated with a dialkanolamide derived from fatty or oily substances of vegetable origin.
