  • Patent number: RE35539
    Abstract: A blood collection device wherein a double-ended cannula is retracted within the barrel of the device for storage and disposal. The cannula is attached to the device immediately prior to use by being threaded into an aperture formed in a movable disc disposed within the barrel and rotated to a locked operating position for attachment of the cannula and use. After use, the disc is counter-rotated to permit the cannula, mounted to the disc, to be longitudinally retracted completely within the barrel to a position in which the cannula is permanently locked by stopping the disc against further movement. The disc aperture is threaded in the same direction as it is rotated to the operating position to avoid moving the disc out of the locked position during attachment of the cannula to the device.

  • Patent number: 5640724
    Abstract: A magnetically activated drain plug apparatus employs a permanent magnet placed externally of a plastic or thin non-magnetic drain pipe while another permanent magnet is placed at the lower end of the drain plug. The external magnet can be a ring shaped magnet, a plurality of magnets in a ring held in a support arm or a magnet slideably retained in a rail on the outside of the pipe. The external magnet is operated by a lever linkage or flexible cable that is external to the drain pipe. Moving the external magnet by operating the linkage or the cable attracts or repels the magnet in the drain plug. Consequently, due to the magnetic attraction or repulsion, the drain plug is moved between an open and a closed position. Guide nubs on the interior of the drain pipe and a stem or fins on the drain plug can be interengaged, thereby preventing tilting or rotation of the drain plug while in the up or open position.

  • Patent number: 5640730
    Abstract: An adjustable articulated bed having a back support section, a head rest section, an angled lifting lever, and a crank assembly operatively connecting the bed motor to the lifting lever. A slidable pin-and-slot arrangement connects the head end of the lever to the head rest section. As the lever is pivoted it first tilts the head rest section up relative to the (horizontal) back support section to a relative tilt position. Continued pivoting of the lever causes it to engage, lift and pivot the back support section up about the lifting-lever pivot axis. The head rest section, while maintaining the relative tilt position, is pivoted up with it. A polyfoam foundation affixed to the tops of both the back support and head rest sections tends to drag or lift the back support section up as the head rest section is pivoted up.

  • Patent number: 5640736
    Abstract: A power feed device for use with a hand held sewer and drain cleaning machine having an elongate, coiled cable and a rotating means for rotating the cable, the power feed device comprising two rollers rotatably mounted on housings, the housings being rotatably mounted within a body of the device, biasing means for biasing one of the housings and thereby one of the rollers toward the cable, cable centering means for centering the cable between the two rollers, means for rotating the roller housings from a "NEUTRAL" position wherein the axes of rotation of the rollers are parallel to the axis of rotation of the cable such that when the cable is rotated in the first rotational direction the cable is not moved along its elongate axis relative to the rollers, to a "FORWARD" position wherein the axes of rotation of the rollers are skewed to the axis of rotation of the cable and such that when the cable is rotated in the first rotational direction the cable moves along its elongate axis in a first direction, or to a

  • Patent number: 5640737
    Abstract: A multi-component sponge has a central or main foam layer of reticulated single cell polyurethane flexible foam and an outer foam layer adhered to each of its two substantially parallel sides so that liquid can flow between the main foam layer and the two outer foam layers. Each of the two outer foam layers is preferably polyurethane flexible foam having a reticulated double cell structure although each could be a reticulated single cell structure having a porosity in the range of 3-110 pores per inch. The main foam layer preferably has a porosity in the range of 3-30 pores per inch. Each of the two outer foam layers is softer than the main foam layer.

  • Patent number: 5640738
    Abstract: A floor cleaning machine having a body carrying a separable rigid vacuum-retaining container, within said container, a flaccid container, means for lifting said containers as a unit from the body of the machine for disposing of spent and unspent liquids contained therein, cleaning the containers, and re-filling with fresh cleaning fluid. In a preferred embodiment, the machine is provided with a full floating squeege which enables the machine to be moved from carpeted surfaces to hard floor surfaces by the simple flip of a handle.
