  • Patent number: 5570632
    Abstract: An apparatus for applying and verifying a printed mark on the periphery of generally cylindrically-shaped objects as they travel on a path. The apparatus comprises at least a first conveyor mounted for movement on a first side of the path. The first conveyor is located to engage the objects to translate the objects at a known translational velocity along the path. A transport assembly is mounted for cyclic movement back and forth along a transport assembly path parallel to the path of the objects at least part of the cyclic movement being approximately at the known translational velocity of the objects. A mark applicator is mounted on the transport assembly and is located in a position to apply a mark on each object as the object is translated by the first conveyor. A sensor is mounted on the transport assembly. The sensor is located in a position to read the applied mark on each object as the object is translated by the belt. The sensor generates a signal representative of the mark.

  • Patent number: 5567930
    Abstract: A sensor apparatus detects displacement of an object in a visually obscured environment. The sensor apparatus includes a tube having a first open end, a second open end and a hollow interior. The tube is in contact with the object. A pressurized gas port is located on the tube in fluid communication with the hollow interior of the tube. A photo-emitter is located adjacent to the first end of the tube, in an aligned position with the first and second ends of the tube. A photo-receiver is located adjacent to the second end of the tube, in an aligned position with the first and second tube ends and the photo-emitter. Movement of either sensor or the tube disrupts the beam between the emitter and receiver. The sensor apparatus has mounting brackets which permit it to be supplied separately as an improvement to a vial washer.

  • Patent number: 5433330
    Abstract: Disclosed is a stopper for use with containers to provide needleless access to the container with a cannula having a blunt penetrating tip. Also disclosed is a system comprising the stopper, container and cannula. The stopper includes a disc having an upper face and a lower face, and a plug extending from the disc into the container. Also included is a diaphragm, defined by a target region in the upper face and a cross channel in the disc for controlling the force needed to penetrate the stopper with the cannula. The plug includes a first inward surface for guiding the cannula and a second inward surface for engaging the cannula to minimize wetting of the outside of the cannula. In a preferred embodiment, the first surface extends down from the cross channel on the lower side of the disc, radially outwardly to a maximum diameter and the second inwardly facing surface extends down from the first surface radially inwardly to a minimum diameter to form the cannula seal.

  • Patent number: 5314084
    Abstract: A closure device for use with a container having an open neck finish, including an inner cap having a skirt terminating in an open end which engages the outside diameter of the finish. The inner cap is sized to initially engage the finish. The skirt has circumferentially spaced slits extending, which may function as lyophilization ports, which permit the inner cap to expand upon an axial closing force and engage the bottom of the finish. A liner is positioned in the inner cap proximate the closed end and is compressed against the finish when the cap is moved to alignment with the bottom of the finish. An outer cap is locked on to the inner cap in pre-assembly which then encloses the inner cap after complete assembly to seal and compress the liner between the finish and the inside face of the inner cap.
