Abstract: Disclosed herein is a process for preparing and applying a coating composition at extremely high pressures under conditions which significantly reduce the amount of volatile organic materials which are given off during the spray process. The spray process involves filling a spray pump receptacle with the coating wherein the spray pump is operable at pressures above about 2,750 psi and wherein the pump is provided with a temperature control means for assuring that the temperature of the pumped coating is in the range of about 65.degree. F. to 120.degree. F. so that the viscosity of the pumped coating is maintained in the range of about 250 to about 1,000 cps. The resulting coatings may be applied as a top coat, sealer, lacquer, etc. to any desired substrate, although wood is preferred, with the resulting finished coating being equal or superior to existing coating compositions.

Abstract: The instant invention involves a process for forming a low formaldehyde, essentially color-free coating composition by applying the composition preferably to a wood substrate and curing. The composition comprises a blend of a polyhydroxy-containing polymer, an hexaalkoxymethylolmelamine, a polyacetal having the formula: ##STR1## wherein R is C.sub.1 -C.sub.3 and A is C.sub.1 -C.sub.20 allyl or aryl and an acid catalyst. The coating compositions of the instant invention exhibit extremely low color and give off a significantly reduced amount of formaldehyde when cured in comparison to conventional prior art, acid catalyzed melamine/formaldehyde cured coatings.

Abstract: A protective needle sheath is described herein which prevents accidental skin puncture and contact by the sharpened end and shaft of a hypodermic needle. The protective sheath is pivoted with a support base molded as part of the syringe or needle assembly, or capable of being fitted to a needle assembly. A retractable arm is pivotally secured to the support base by a live hinge. The retractable arm being capable of moving from a position in which the needle is encased in a needle channel in the arm, to a position exposing the needle. The retractable arm is moved by applying force to an arm actuator attached to the arm. The needle is locked within the needle channel by friction lock tabs located in the needle channel. The lock tabs are released by applying force to squeeze tabs attached to the arm.

Abstract: Disclosed herein is a hemostasis valve which is formed of a longitudinally extended valve housing having a first opening and a central longitudinal passage communicating with an opposite second opening. A cap means is provided for enclosing the first opening of the housing, said cap means having a hole to permit insertion of a catheter. Also provided is a one-piece seal means located within the longitudinally extended housing, said seal means comprising a sealing neck having a relatively small opening therein and communicating with a slit concave exit base.

Abstract: A method and apparatus is described herein which allows filters, to which bacterial or mammalian cell samples have been absorbed, to be reacted sequentially by various scientific means and to be washed between analyses. The filters are placed between interconnected parallel separation plates on the filter agitator. The filter holder is lowered into a reaction container that contains reaction or wash solutions. The filter holder is raised or lowered in the reaction container by physical or mechanical means. The reaction container is covered by a lid which prevents splashing and contamination of the solution or filters. Solutions are added by means of a fill tube located in the lid and emptied by means of a drain in the reaction container. Once the sequential analysis is complete, gene product on the sample filters is detected by an appropriate method.

Abstract: Disclosed herein is a conductive polymeric coating having a charge density of greater than about two which, after being applied to a nonconductive substrate, allows overcoating of that substrate by electrostatic spraying. Exemplary of the conductive polymeric coatings useful herein are those based upon quaternized homopolymers or copolymers of dimethyldiallylamine.

Abstract: Disclosed herein is an iron holder which is comprised of a pair of essentially parallel and vertical arm means attached to clamp means for securing the arm means to an ironing board, wherein the arm means are sufficiently spaced apart to receive an iron which is placed on end. In the preferred embodiment the arm means and the clamp means are adjustable so as to accommodate various sizes of irons and various sizes of ironing boards.

Abstract: This invention involves a unique wood and furniture coating composition comprising about 50 to about 85% by weight of an acrylated cellulosic, about 15 to about 45% by weight of an acrylated oligomer about 0.1 to about 10% by weight of a ultraviolet photoinitiator and sufficient solvent to render the resulting solution handleable under processing conditions. The resulting coating may be applied by a unique process that involves spraying the coating over a base coated wood substrate, flashing the solvent off, rubbing, sanding or otherwise processing the coating and then ultraviolet curing the coating by subjecting the coating to ultraviolet curing conditions. The resulting coating possesses excellent cured state film properties and good chemical resistance. Its film properties are at least equivalent to prior art cellulose nitrate coatings but it is far superior to these coatings in terms of its chemical and water resistance.

Abstract: Disclosed herein is a process for treating scrap thermoplastic film which has been treated with a saran coating. When the scrap film is cut into a convenient size, it is densified in the presence of a treatment medium which comprises a mixture of lime and an alkyl carboxylate and molded into pellet form. These pellets may then be employed in conventional extrusion and molding equipment without any degradation of the equipment which was normally seen when untreated saran-coated, scrap films were attempted to be molded or extruded.

The resulting epoxy resin curing agent may be used in a solvent based system to cure epoxy resins under low temperature curing conditions.

Abstract: An aqueous coating composition based on a highly stable emulsion of polymerized monomers curable in the presence of a strong acid catalyst at low temperatures and therefore usable on thermoplastic substrates. The emulsion includes non-functional monomers whose combined glass transition temperature is such as to give desired hardness and flexibility required of highly demanding product applications. Water miscibility and extended period stability of the emulsion is maintained in the presence of the strong acid catalyst by use of disclosed surfactant agents which are alkoxylated and/or etherified as needed to impart these characteristics. A high degree of solvent resistance is achieved by addition of a hydroxyl functionality to the emulsion for reaction with the crosslinking agent in the presence of the acid catalyst. The emulsion suitable for the coating composition is also set forth.

F. and below while the basecoat is selected for compatibility with the topcoat and the substrate, either the metal or plastic, to give proper adhesion, flexibility, film integrity and lack of interference with topcoat performance.
