  • Patent number: 6379332
    Abstract: A needle protector assembly for protecting a needle tip after it has been withdrawn from a catheter has a protective housing into which the needle is slid. A device at the patient end of the housing has two locking arms sprung outwardly away from one another, which engage projections on the hub of the catheter. A shutter plate and finger project inwardly from the locking arms and each has a catch that engages one another. The finger is sprung rearwardly away from the shutter plate but is held forwardly by a trigger lever engaging the side of the needle. When the needle is withdrawn into the housing, the trigger lever springs down allowing the finger to move rearwardly away from the shutter plate, thereby disengaging the catches. This allows the locking arms to spring outwardly and disengage the catheter hub, so that the assembly can be removed from the catheter.

  • Patent number: 6226809
    Abstract: An hydraulic bath seat lift has a hydraulic cylinder assembly comprising an inner cylinder fixed with the floor and an outer cylinder, which can be raised and lowered by supplying hydraulic fluid to the assembly. The outer cylinder supports a seat at the end of a horizontal arm. The inner cylinder has a pin at its upper end projecting outwardly into one of two sets of longitudinal grooves along the inner surface of the outer cylinder to prevent the outer cylinder rotating relative to the inner cylinder. The grooves open into one another at the lower end of the outer cylinder so that when the outer cylinder is raised fully, to lift the seat above the bath, the cylinder can be rotated to swing the seat over the bath and then lowered with the pin engaging the other set of grooves.

  • Patent number: 6212445
    Abstract: Methods and apparatus for generating a linear vibratory output force having a variable amplitude. The force is generated by the cooperation of four rotating eccentric masses that are grouped in two pairs of two masses. The masses in each pair are counter-rotating (i.e., they rotate at the same speed but in opposite directions). The phase relationship between the two pairs is adjustable. For example, the phase of one pair can be advanced while the phase of the other pair is retarded by an equal amount, thereby changing the amplitude of the output force without changing the direction along which the force acts, and also without changing its frequency if desired.

  • Patent number: 6196303
    Abstract: A heat exchange assembly has a heat exchanger, a fan at one side and a drain tray assembly extending beneath the heat exchanger. The heat exchanger has a pipe along which heated or cooled water is supplied, and a stack of vertical, parallel plates between which the fan passes air. The drain tray assembly has a tray with a peripheral wall and a drain outlet at one end. An inverted gutter fits loosely within the tray spaced from its edges by two channels. The height of the gutter is such as to block the space between the upper surface of the tray and the underside of the heat exchanger so as to prevent air flow beneath the heat exchanger.

  • Patent number: 6161815
    Abstract: An hydraulic valve has a flow/pressure characteristic matched to that of a pump with which it is used. The valve has a housing with a fluid inlet in its side and an outlet at one end. A shuttle is movable along the housing under control of a proportional solenoid, to vary the amount by which an edge of the shuttle covers the inlet and thereby controls flow of fluid through the valve. The shuttle has a flange one end located between the inlet and outlet so that fluid flowing from the inlet to the outlet applies pressure to one side of the flange and displaces the shuttle to close the inlet. In this way, an increase in pressure tends to reduce the effective size of the inlet aperture to compensate for pressure variation.
