  • Patent number: 6052851
    Abstract: A mattress which increases the surface area contacting the patient's skin, and which conforms evenly to the skin over the skin/surface interface. A mattress includes a flat layer of foam that is temperature sensitive and which has rate-dependent deflection which provides maximal hysteric dampening and maximal tissue/surface interface contact. Different stiffnesses of foam are used under key areas to allow support and at the same time to allow the tissue to reach mechanical equilibrium. The maximal surface contact will apply constant low pressure to the tissues, thus reducing the shear force and the risk of tissue injury.

  • Patent number: 6052862
    Abstract: A cord rewinder assembly for a wet filter type vacuum cleaner with a moist air discharge outlet includes a conventional cord rewinder and a deflector plate. The deflector plate not only shields the cord rewinder from direct contact with the moist airflow discharge but also functions to remove moisture from the airflow so that it can be utilized to cool the electrical components of the cord rewinder. Incoming air carrying dirt and dust is cleaned by passing the air stream through a canister of water and a series of secondary filters. The clean discharge air, which contains moisture and water vapor, impinges on the deflector plate and is redirected downwardly at a high velocity toward a cavity. The airflow enters the cavity at a lower velocity, passes beneath the deflector plate and reverses direction. The decrease in airflow velocity and the redirection of the airflow allows the moisture and water vapor to drop out of the airflow.

    Abstract: A gutter broom (8) for a pavement sweeper is defined by an annular brush disc (24) having a central opening and from which a series of equi-spaced conventional bristle blocks (11) are removably secured. A downwardly depending air foil (18) is secured to the underside of the annular brush disc (24) between each bristle block (11). A series of equi-spaced radially aligned fan blades (17) are secured to the opposite side of the annular brush disc (24) and function to define a radial flow fan. A stationary fan scroll (20) is formed over and contains the radial flow fan and includes an air flow outlet (23). When the gutter broom (8) is rotated, the air foils (18) function to draw ambient air and any entrained dust/debris into the brush structure with the resultant air streams directed to the radial fan structure, which, in turn, directs the dust/debris laden air stream to the outlet (23).

  • Patent number: 6052873
    Abstract: A shaped clip includes a metal band having axial flanges, a first clamping wall and a second clamping wall. A barb is bent over on the radially outer end of the first clamping wall. A barb has a first hook section and a second hook section. A latching hook is connected to a radially outer edge of the second clamping wall. The latching hook is formed from an L-shaped planar strip and has a first limb and second limb. To move the shaped clip from an open position to a closed position, the clamping walls are pressed together the so that the latching hook is latched to the barb by sliding an inclined surface of the second limb against an inclined end surface of the second hook section radially inwardly, over and beyond the inclined end surface of the latching hook thereby latching the shaped clip into a retention position.

  • Patent number: 6052874
    Abstract: As a preferred alternative to whipping a boat-line with tape or a wax material to limit wearing and unraveling over time, the apparatus of the invention affords a secure, more attractive appearance through the use of a pair of cylinders, one of which receives the boat-line, and the other of which threads over it, with the effective screwing of the two together additionally producing a force upon a series of compressible fingers that extend inwardly from the outside surface of the first cylinder in clamping onto and holding the boat-line in position. The two cylinders may be capped in providing a finished-off appearance to the construction when the line is thus secured.
