  • Patent number: 4290604
    Abstract: A racquetball racquet having a metal frame is disclosed, wherein increased stiffness in the metal frame is provided by a grooved contact between the inner surfaces of the frame comprising the outer perimeter of the racquet and a throat piece, completing the reinforced enclosure within which the strings are arranged. This grooved contact of the throat piece with the metal frame further resists the stress and strain of contact between the racquet and the racquetball, such that the entire surface of the strings behaves in a uniform and predictable fashion.

  • Patent number: 4286020
    Abstract: A method and composition for the in-flight encapsulation of particles such as insecticides, herbicides, molluscicides, acaricides, fungicides, nutrients, pheromenes, odorants, fragrances, attractants, repellants, trace elements, and the like. The composition comprises, by weight, from 1 to 40 percent of said particles, from 0.3 to 25 percent of a film-forming polymer and from 35 to 99 percent of a solvent which renders said polymers soluble. Often, other compounds may be added to impart desirable properties such as a second film-forming polymer, crosslinking agents, film modifying agents, and adhesives to improve adhesion to a target. The particle may be in a true solution suspended or emulsified through the action of surfactants and/or emulsifying agents. The film-forming polymer is selected from the class consisting of polyvinyl ethers, polyvinyl acetate, and interpolymers of alpha-beta olefinically unsaturated carboxylic acids and N-methylol acrylic amides, as set forth in U.S. Pat. No. 3,007,887.

  • Patent number: 4284984
    Abstract: An attitude change alarm for securing articles from theft or other undesired movement. The alarm includes a case having a wall which defines a hollow interior. Resistive elements are maintained within the wall in spaced relationship with each other and in common communication with an electrically conductive surface on the outside of the wall. An electrically conductive member is fixedly maintained in the hollow interior in constant contacting engagement with a conductive fluid which makes selective engagement with certain of the resistive elements. When the alarm is moved, a current is transmitted from the conductive coating through the resistive elements, fluid, and member, and is passed to a transformer which gates an SCR into conduction, activating the alarm. Various geometrical configurations of the attitude change alarm are presented, each having specific attributes associated therewith.

  • Patent number: 4281546
    Abstract: An apparatus and method for cutting elastomeric material into volumetric elastomer samples is disclosed. These volumetric samples may be reproduced at identical mass for precision testing purposes. The volumetric samples are reproducible for such precision purposes by the use of a volumetric adjustment mechanism which determines the volume of the cavity into which elastomeric material is compressed before cutting. The apparatus also has a moving cutting mechanism with a contoured cutting area, which in combination with the volumetric adjustment apparatus, removes deleterious air bubbles and other deformities prior to cutting the elastomeric material. The volumetric adjustment apparatus is housed within a die apparatus, which has a damping mechanism to permit complete manipulation of the elastomer prior to cutting the elastomer into the volumetric plug. After the cutting of the plug has occurred, the ejection apparatus pushes the volumetric plug from the cavity whereupon another cycle is begun.

  • Patent number: 4277296
    Abstract: The invention relates to the use of reinforcing cords associated with the pneumatic tire to control radial force variations in the tire under loaded conditions, and the method of applying such reinforcing cords woven in a warp and weft relationship cut on a bias or circumferentially to form a belt, such belt extending past the lateral edges of the present belt and applied to the tire either in its new form or as a retreaded tire from an old carcass. It can be extruded into the tread material as it is initially formed. Basically, the cords are made from a very high strength material, either synthetic, wire, or the like, having a tensile strength of approximately 125 psi each, with the cords spaced at approximate 1/4 inch spacings. Hence, there will be four cords, more or less, per inch. The cords could be increased to 150 or more pounds each.

  • Patent number: 4276710
    Abstract: A device for harvesting shrimp, prawn, and other aquaculture from man-made ponds. The device includes an elongated truss which is maintained at each end thereof by a carriage. Depending from the truss are a plurality of support arms maintaining at the ends thereof rows of flexible tines. A net extends between the support arms and is connected to the tines. The truss is maintained above the pond with a carriage on each side and is moved over the pond such that the tines contact the pond bottom, stirring aquaculture therefrom and into the net. Preferably, the pond is of a rectangular shape having an inclined ramp at one end thereof, the ramp emptying into a trough, such that the device may move the aquaculture up the ramp and into the trough from which it may be finally harvested.

  • Patent number: 4276394
    Abstract: Novel telechelic halogenated polymers of cationically polymerizable olefin monomers are formed carrying from 2 to about 6 terminal halogens. The telechelic halogenated polymers are formed by reacting the monomer with an initiator transfer agent, carrying at least two tertiary halogens, and under cationic polymerization conditions. Additionally, novel thermoplastic elastomer block copolymers are formed from these telechelic halogenated polymers by reacting the latter with vinyl aromatic monomers in the presence of a coinitiator.

  • Patent number: 4274557
    Abstract: A beverage dispenser pumping system having a mass reservoir for receiving a plurality of beverage-containing bottles in such manner that all of the bottles feed a common line but no intercommunication of beverages among the bottles is possible. The mass reservoir feeds a pessurized pump which is operative for driving an expandable and contractable dispensing line. A dispensing valve is located near the end of the dispensing line for initiating and terminating the flow of beverage from the pump, through the line and out of a dispensing head. A one-way valve interposed within the dispensing line and closely adjacent the pump retains liquid pressure within the line and inhibits any bleeding of beverage from the line back into the pump when dispensing has terminated. A hydraulic accumulator is presented between the dispensing valve and the dispensing head to withdraw beverage from the end of the dispensing line when the dispensing valve shuts off so as to prohibit extraneous drippage from the line.

  • Patent number: 4274187
    Abstract: A spring installation tool for article loading machines is provided to facilitate the application of a biasing spring to sets of guide fingers. Fundamentally, the invention includes an elongated frame member having a tubular portion at a first end thereof for receiving the biasing spring. A rod is provided having a ring at one end which encompasses the tubular portion while being maintained in spring-biased engagement at an opposite end thereof with a second end of the frame member. The rod is operative for reciprocating movement with respect to the frame member to effectuate forcing of the biasing spring from the tubular portion. In use, the tubular portion, bearing a biasing spring, is placed over the end section of a set of guide fingers and the rod is reciprocated to force the spring from the tubular portion into securing and biasing engagement with the fingers.
