Abstract: Hot products of combustion are provided beside an outer surface of a load to be heated, and are given a non-uniform temperature profile in a control direction extending across the outer surface of the load. The non-uniform temperature profile of the hot products of combustion is varied within a range that is predetermined relative to the distance that the outer surface of the load extends in the control direction, whereby the load can be given a predetermined temperature profile in the control direction.

Abstract: A tubular telescoping drive shaft for transmitting rotation from a rotating power source to an element to be rotated thereby, including at least one inner member or shaft telescopically receivable in an outer tubular shaft and including a universal joint such as a Hooke's joint having pivotal yokes connected with a cross link, all of which are at least substantially received within the outer tubular shaft in a fully retracted position and are rotatably pivotable therein for accommodating misalignment of the rotating power source and element rotated thereby.

Abstract: A multi-rotor blower fan assembly for a cotton picker utilizes a plurality of separate fan enclosures each containing a fan for supplying an individual air flow to a picker unit of the picker, the fans being mounted on a common shaft for rotation therewith, with a unitary removable or openable cover or hood covering access openings of the fan enclosures. One or more of the fan assemblies can be mounted on the picker, for instance, on an existing platform on the picker chassis just rearward of the operator cab, in end-to-end relation, and rotatably driven using a common drive.

Abstract: A vaginal cleaning apparatus for cosmetic purposes which overcomes the disadvantages of commercially available douches. The apparatus comprises a solution chamber incorporating a plunger for expelling substantially all solution contained in the chamber through an attached cannula. A sponge applicator is attached to one end of the chamber surrounding the cannula. The cannula is in the form of a tube having a single opening for discharge of solution at its tip. The sponge applicator has an expanded shape approximately the inner configuration of a vagina. The sponge applicator is initially compressed for ease of insertion and expands from its tip as the solution is discharged. The chamber volume and application absorption are preferably matched to minimize dripping of the solution. The cannula and applicator extend at an angle with respect to the chamber to allow use of the apparatus in a standing or sitting position.

Abstract: A method of improving the wet-strength characteristics of a plaster of Paris cast is disclosed. The cast bandage is immersed in dip water which contains 2%-15% by weight of a fluorochemical or the fluorochemical is applied to the finished cast. The fluorochemical is dispersed in the water by a nonionic or cationic surfactant. The resulting cast has improved water-resistant properties.

Abstract: Improved stable, aqueous resin compositions comprising from about 0.1% to about 60% by weight on a solids basis of a synthetic resin and from about 0.01% by weight to about 6% by weight, based on the weight of the synthetic resin, of an aluminum chlorhydroxide complex from the group consisting of: (a) aluminum chlorhydroxides; (b) reaction products of aluminum chlorhydroxides and polyhydroxy compounds; (c) reaction products of aluminum chlorhydroxides and monocarboxylic acids; (d) and mixtures thereof; and methods of utilizing the same.

Abstract: The separation of a sample of blood into serum and clot portions is accomplished by means of a sealant consisting essentially of a silicone fluid and silica dispersed therein. The separation is accomplished by inserting a supply of the sealant into a container holding a sample of the blood. The container and device are centrifuged so that it separates into serum and clot portions and the sealant, having a specific gravity of at least 1.026, separates the two portions.

Abstract: The separation of a sample of blood into serum and clot portions is accomplished by means of a sealant consisting essentially of a silicone fluid and silica dispersed therein. The separation is accomplished by inserting a device containing a supply of the sealant into a container holding a sample of the blood, the device being characterized by a nozzle portion which extends into the sample. The container and device are centrifuged so that it separates into serum and clot portions and the sealant, having a specific gravity of at least 1.026, separates the two portions.

Abstract: Synthetic resin compositions comprising: (1) a synthetic resin; (2) a polyvalent metal complex coordination compound; and (3) a water-soluble, ionically-active ammonium or alkali metal salt of an acid capable of being chemically converted into an ionically-inactive polyvalent metal salt of said acid by chemical reaction and precipitation or sequestration of said polyvalent metal salt.
