  • Patent number: 5740588
    Abstract: Maximum separation of the seed cotton locks delivered to a cage roller gin is achieved by a ballistic trajectory that carries the locks over the top of the cage roller to a landing area. In the preferred embodiment, the flight of the locks over the cage roller is induced by a pair of oppositely driven rollers which expel the cotton from between their adjacent surfaces along a common tangential plane offset at an angle above the top of the cage roller. Ambient air is admitted to the relatively large volume plenum from beneath the rollers and a primary flow of air about the cage roller is promoted as the seed cotton overlies the rotating cage such that the air and injected seed cotton locks flow in co-current direction above the cage roller.

  • Patent number: 5601870
    Abstract: A multi-layer flexible article includes a first layer of natural rubber, a second layer of natural rubber, polyurethane, poly(acrylamide/acrylic acid) and polyethylene oxide and a third layer of acrylic copolymer and fluorocarbon telomer resin. The article is preferably a glove formed by the method of dipping a hand shaped mold into baths containing aqueous emulsions of the components used to form the layers. Gloves manufactured according to the method are substantially wet-hand and dry-hand donnable as compared to powdered latex gloves of similar size. The finished gloved is water washed and wet autoclaved to substantially reduce the protein content from the natural rubber and substantially remove other water extractable allergenic moieties. The washing and autoclaving renders the glove substantially hypoallergenic as compared to gloves not so treated.

  • Patent number: 5577403
    Abstract: An identification system utilizes a plastic housing which is appropriately sized to hold either a key or a coin as well as an information sheet on which the user may place selected indicia referring to the key or to himself. Each embodiment utilizes a living hinge closure attachment to secure the key or coin and information sheet within the housing. Utilizing the housing as the indicia for identifying the key minimizes the excess material and connections thereby simplifying the identification and storage problem, yet because the use of the housing with the key slightly increases the size of the key head, it provides a slightly greater moment arm for turning the key in a lock and gives a slightly larger gripping surface to be employed when so turning the key. These factors are significant when dealing with children and with elderly people who may not have the physical strength and dexterity required for some small headed keys.

  • Patent number: 5552566
    Abstract: An improved apparatus for deconcentrating an electric field surrounding a high voltage insulator. A clamp assembly centrally formed within a coronal ring permits positive placement of the coronal ring about an insulator end fitting. The clamping assembly comprises an integral clamp with a u-shaped opening for engaging a cylindrical portion of an insulator end fitting. A keeper clamp mounts superjacent to the integral clamp and a smaller second u-shaped opening engages a portion of the insulator end fitting having a smaller diameter. A captive fastener such as a bolt extends upwardly through the clamp and keeper clamp to secure the keeper clamp in position against the insulator end fitting and the integral clamp to secure the corona ring in position relative the insulator end fitting and sheds. The varied sized openings of the clamp and keeper clamp prevent inverted installation of the corona ring.

  • Patent number: 5546855
    Abstract: A bale tying apparatus for use with a baling press distinguished from the prior art mechanisms in that the articulated arms which shape wire ties about a bale also incorporate elements on the ends thereof to effect the tying of the wires without engagement of the wires with positioning surfaces in the follow block of the press. Thus the tying function is made more reliable and is independent of the follow block precise positioning. A wire loop on at least one end of the wire tie remains in contact with the arm mechanism until the wire knot is made up. The apparatus may use wire loop holding devices at the ends of both arms or may use a housing carried on the end of one arm with an opening for insertion of the other end by the other arm.
