Patent number: 5863614Abstract: An apparatus for applying a coating to an object includes a pair of reciprocating members which each include a porous resilient pad mounted for movement toward and away from each other. The apparatus includes a coating supply system for supplying coating to the resilient pads. The pads have a movement sequence from an initial rest position where the pads are spaced apart from one another to a coating loading position where the pads are in physical contact and have a degree of compression with each other to load the coating onto the pads, then the pads are moved to an intermediate rest position with the pads spaced apart an the object to be coated is moved between the pads. The sequence then includes a coating delivery position where the pads are in physical contact with each other and the object so that the pads have a degree of compression with each other and the object thereby applying the coating to the object.Type: GrantFiled: May 28, 1997Date of Patent: January 26, 1999Assignee: Becton Dickinson and CompanyInventors: Victor A. Williamitis, Jeanne E. Lambert, Min Shiu Lee, Robert A. Taller

Patent number: 5773081Abstract: An apparatus for applying a coating to an object includes a pair of rotating members each including a porous resilient roll mounted for counter-rotatory movement. The members are mounted so that they contact each other during a segment of the movement and are out of contact with each other at other segments of the movement. The apparatus includes a coating supply system for supplying a coating to the resilient rolls. The rotatory movement of the members includes a coating loading segment where the resilient rolls are in physical contact and have a degree of compression with the coating supply system for loading the coating into the rolls. The sequential movement also includes an intermediate segment where the resilient rolls are out of contact with each other and where an object to be coated is movable into position for movement between the resilient rolls when the rolls are in a coating delivery segment.Type: GrantFiled: July 31, 1997Date of Patent: June 30, 1998Assignee: Becton Dickinson and CompanyInventors: Victor A.

Patent number: 5302392Abstract: A polyurethane composition has particles of solid polyvinylpyrrolidone-iodine complex evenly distributed throughout the polyurethane matrix so that the complex does not associate with the polyurethane to any appreciable extent. In one embodiment of the composition, the polyurethane is thermoplastic for coating or molding applications. In another embodiment, the composition is a polyurethane foam particularly useful as a sponge for scrubbing which provides almost instantaneous release of the complex. The sponge may be provided in a package which includes other items useful for scrubbing.Type: GrantFiled: August 20, 1990Date of Patent: April 12, 1994Assignee: Becton, Dickinson and CompanyInventors: Mutlu Karakelle, C.
