  • Patent number: 4813939
    Abstract: There is disclosed a winged infusion apparatus for use with patient implantable access ports. Essentially, the apparatus includes a composite disc housing which is circular in configuration and has integrally formed therewith two winged sections which overlie arcuate apertures in the sides of the disc. A cannula is embedded within the internal body of the disc, and via a right angle bend the cannula emanates from the bottom surface of the disc at a central location. The winged members are operable so that they can be grasped by a user and placed in an upright position via integral hinges associated with each winged member. In this manner the user can then insert the cannula into an axis port which is implanted in a suitable body cavity of a patient and which has an output aperture on the patient's skin.

  • Patent number: 4759289
    Abstract: A synthetic resinous bearing having hydrophobic properties which continuously expel collected waste ink from an ink transfer roller of a printing press. The bearing consists of a molded sleeve of synthetic resinous material such as sintered Teflon or molded nylon which has been impregnated with a compatiable lubricant such as molybdenum disulfide or the like. The bearing includes longitudinally oriented grooves on an inner surface thereof which are not wetted by the flow of waste ink and contaminants, and which provide for continuous discharge of the same during operation of the associated printing press.

  • Patent number: 4241908
    Abstract: A clamping device which holds one half of a folded jacket against an inclined platen as an insert is dropped into the jacket against the fold. The platen is one of a large number of similar elements carried by a carousel which intermittently shifts the platens from station to station, the clamping device being rendered operative at one station and continuing to remain operative through several stations as one or more inserts are dropped successively into the jacket. The clamping device prevents the pages of the jacket from blowing open as inserts are dropped. The clamping device constitutes a flexible resilient arm, one end of which is fixed to an oscillating clamping bar that reciprocates the clamping device between an idle and an operative position. The tip of the arm supports a resilient pad that, when the arm is in operative position, presses against the inner surface of the jacket half that rests against the inclined platen.
