  • Patent number: 7634820
    Abstract: An adjustment mechanism for a helmet. A first sliding surface is defined in a first portion of the helmet and includes an opening. A second sliding surface is defined in a second portion of the helmet. Two spaced apart arms extend from the second sliding surface. The first and second sliding surfaces are in sliding engagement with one another with the arms sliding within the opening. A lever is pivotally connected to the first portion in proximity of the opening and pivotable between a locked position and an unlocked position. The lever has a series of regularly spaced apart parallel teeth which in the locked position protrude through the opening with at least a selected one of the teeth being engageable between the two spaced apart arms to prevent the first and second sliding surfaces from sliding relative to one another.

  • Publication number: 20090206127
    Abstract: A tissue fastener includes a bridge section and two cannulated leg sections. The tissue fastener is a single piece of material, and the material can be a bioabsorbable material. Each of the two leg sections can include at least one barb for resisting dislodgement from tissue after the fastener is inserted into tissue. The bridge can be flexible, and the leg sections can receive needles to allow insertion of the fastener into tissue from above a surface of the tissue. Various insertion devices and mechanisms are possible to deploy the fastener into a wound in a patient's skin from above the surface of and generally perpendicular to the skin.

  • Patent number: 7178175
    Abstract: An improved retention system for a protective helmet comprises slide/coupling mechanisms on opposite sides of the helmet shell, and a movable element at the rear of the helmet. Fastening of the chinstrap secures the helmet in the downward direction and tightens the movable element against the nape of the neck, thereby securing the helmet in the area of the occipital lobe.

  • Patent number: 5952099
    Abstract: Electrically conductive thermoplastic fibers are made by spinning a fiber having an electrically conductive sheath of thermoplastic polymer formulated with carbon black and a non-conductive core from the thermoplastic polymer; quenching the fiber after said spinning to a temperature below the melting point of the thermoplastic; drawing the quenched fiber at a draw ratio between about 2.0 and about 3.2; and, after drawing, relaxing the fiber at a temperature below the melting point of the thermoplastic but above its glass transition.

  • Patent number: 5741532
    Abstract: An apparatus for melting particulate polymeric material includes a melting grid and a molten polymer reservoir beneath the grid. The apparatus has a lateral cross-sectional contour defined by walls. Further included is a distribution device having upper and lower surfaces and adapted to the contour of the molten polymer reservoir, which device is disposed in the molten polymer reservoir in proximity to the grid. The device has an internal reservoir formed between the upper and lower surfaces; a perimetrical surface joining the upper and lower surfaces and providing the device with height; at least two fluid distribution pores, each having one end in communication with the internal reservoir and another end disposed in the circumferential surface; and an injection tube providing fluid flow communication between the internal reservoir and an external supply of fluid.

  • Patent number: 5614142
    Abstract: Fibers are made from thermoplastic polymers by supplying solid particles of the thermoplastic to a melting grid; heating the melting grid to a temperature sufficient to melt the thermoplastic; melting the thermoplastic particles on the heated melting grid such that the melted thermoplastic flows through the grid and is collected in a collecting chamber located beneath the melting grid; injecting into the collecting chamber below the melting grid an additive present in a non-aqueous carrier which carrier comprises organic rosin materials and a surfactant; without actuated mechanical stirring, forming a substantially homogeneous mixture from the injected additive; and extruding fibers from the substantially homogeneous mixture.

  • Patent number: 4477578
    Abstract: Method and apparatus are provided for carrying out multiple simultaneous transfers of fluid. The method and apparatus are particularly directed toward immunoassays wherein immunologically active compounds, such as antigens and haptens, are detected through their associated antibodies. The device relies on the ability to transfer fluids, such as biological samples and reagents, between a reservoir and an associated receptacle. By providing a receptacle having a port at its lower end and which is otherwise hermetically sealed, such fluid transfer can be effected by immersing the port beneath the surface of the fluid in the reservoir and manipulating the pressure on the remaining surface area outside the port. The transfer of biological fluids at positive pressure provides enhanced fluids flow characteristics, particularly reduction or elimination of the tendency of these fluids to froth or bubble.

  • Patent number: 4416778
    Abstract: A method of preparing neocyte-enriched blood is disclosed wherein a contained sample of whole blood is centrifuged at high speed so as to distribute the blood components in said chamber along a density continuum. Following the high-speed centrifuging step, the blood components in the first chamber are partitioned by transferring those components beyond a selected partition line in the first chamber from the spin axis to a second chamber so that the blood components in the first and second chambers can be used independently. Apparatus for effecting the separation and partitioning of the blood in a completely sterile environment is also disclosed.

  • Patent number: 4210026
    Abstract: A hand-held device for causing a blood sample to be controllably drawn into a flexible envelope or the like. The envelope is placed between a rigid and a hinged member disposed within the housing of the device, and a roller advanced along the hinged member to progressively compress the envelope. When the wheel is moved back along its path, the envelope is allowed to progressively expand thereby drawing the blood sample into the envelope.
