Abstract: Water-soluble protein is coated onto particles of nitramines by making a rry of nitramine powder in a water solution of the protein and removing the water by evaporation or by filtration after previously precipitating the protein by addition of ethanol. The protein coating acts as a bonding agent to enhance the bond strength between propellant binders and the nitramine particles, resulting in substantial enhancement of desirable propellant properties.

Abstract: A carboxylated latex is added to an aqueous slurry of fibers to remove metal ions contained in solution. The water is removed to form a felt. The demetallized water removed during felt formation is recycled in a closed process water system. The carboxylated latex is formed by polymerizing an unsaturated carboxylic acid on a substantially surfactant free styrene-diene polymer latex.

Abstract: A Malone-type final stage for utilization in a Stirling cycle cryogenic cooler apparatus includes a displacer slidable within a vessel. .sup.4 He, .sup.3 He, or a mixture thereof is made to flow in a pulsating unidirectional manner through a regenerator in the displacer by utilization of check valves in separate fluid channels. Stacked copper screen members extend through the channels and through a second static thermodynamic medium within the displacer to provide efficient lateral heat exchange and enable cooling to temperatures in the range of 3-4 K. Another embodiment utilizes sintered copper particles in the regenerator. Also described is a final stage that has a non-thermally conducting displacer having passages with check valves for directing fluid past a regenerator formed in the surrounding vessel.

Abstract: A process is disclosed by which thermoplastic elastomers may be utilized to repare melt-formable composite rocket propellants. The thermoplastic elastomer is dissolved in a volatile organic solvent, the other propellant ingredients are mixed in, and the volatile organic solvent is evaporated. The dried propellant is melt-formed to final shape by molding or extruding above the melting point of the elastomer. An example of a usable thermoplastic elastomer is a block copolymer comprised of about 5 to about 20 weight percent styrene and of about 80 to 95 weight percent diene. The formed grain can be reclaimed by melting or dissolution in an organic solvent for reuse of the propellant ingredients.

Abstract: The present invention is a device for use in combination with a loudspeaker system, that includes a speaker enclosure, in order to effectively enlarge the volume of the speaker enclosure thereby increasing the apparent compliance of the speaker enclosure. The loudspeaker system also includes a vibratable cone. The device may also permit the varying of the mass of the moving system with respect to frequency. The device for effectively enlarging the volume of the speaker enclosure includes a gas having a Joule-Thomson coefficient of less than zero above its inversion temperature, and an inversion temperature below the ambient temperature of the environment in which the device is to be used.

Abstract: A heat transfer device is described that can be operated as a heat pump or refrigerator, which utilizes a working fluid that is continuously in a liquid state and which has a high temperature-coefficient of expansion near room temperature, to provide a compact and high efficiency heat transfer device for relatively small temperature differences as are encountered in heating or cooling rooms or the like. The heat transfer device includes a pair of heat exchangers that may be coupled respectively to the outdoor and indoor environments, a regenerator connecting the two heat exchangers, a displacer that can move the liquid working fluid through the heat exchangers via the regenerator, and a means for alternately increasing and decreasing the pressure of the working fluid. The liquid working fluid enables efficient heat transfer in a compact unit, and leads to an explosion-proof smooth and quiet machine characteristic of hydraulics.

Abstract: A diaphragm for a flush valve is made of molded rubber with a plastic insert for strengthening the diaphragm. The insert includes reinforcing means located at the points where the diaphragm is attached to the valve parts. There is also a plurality of spaced, rigid sections placed between the points of attachment. Connecting means are provided for connecting the reinforcing means and the rigid sections together. The connecting means is arranged to permit flexibility of the diaphragm in two planes. Thus, the diaphragm is permitted to flex both in the plane of the diaphragm and perpendicular to the diaphragm.

Abstract: A method for oven drying chemically modified cellulosic materials, especially fibers, having improved fluid absorbency involves incorporating into the cellulose structure while swollen an amphiphilic compound miscible with water which will not evaporate when the fiber is oven dried and will remain in the fiber to prevent collapse of the fiber as the water is removed. The improved method of drying the fibrous cellulosic material produces a product having saline absorbency about equal to that produced when the fibers are dried with a water-miscible solvent and avoids the use of volatile solvents and the disadvantages inherent therewith. The fibers provided by the invention are especially suitable for use in pads which are to be used for absorbing water and body fluids.

Abstract: The production of hydrocarbons from a subterranean hydrocarbon-bearing formation containing acid-soluble components, such as one composed at least in part of dolomite or limestone, is stimulated by injecting into the formation usually via casing and cement pack perforations a composition comprising an aqueous solution of a mineral acid having dissolved therein a small amount of a vinylpyrrolidone polymer or an alkoxylated vinylpyrrolidone polymer. The increase in the permeability and porosity of the formation achieved utilizing the method of invention results in a substantial improvement in hydrocarbon recovery. Optionally, the injected composition may be saturated with natural gas at the injection pressure. In another embodiment this invention relates to the oxyalkylated vinylpyrrolidone polymer compositions.

Abstract: A track assembly for a sliding closure member comprising a track extending in a longitudinal direction. A support arm is mounted at one end in the track for travelling movement along the track by a connecting means which retains the arm generally perpendicular to the track during part of the travelling movement. The connecting means also permits rotation of the arm about an axis perpendicular to the common plane of the track and arm in one end region of the track. The connecting means comprises a ball roller mounted on the arm for rolling movement along the track when the arm is generally perpendicular to the track. The ball roller also permits rotation of the connecting means about the axis perpendicular to the common plane of the arm and the track. A holding means engages the connecting means to prevent such rotation when the connecting means is not positioned in the end region of the track.
