  • Publication number: 20100327505
    Abstract: Disclosed is a clamp that includes a bolt, a spacer, a shank, an expander and a blocking means. The bolt includes a non-threaded undercut that permits the bolt to rotate in an internally threaded portion of the spacer without threaded engagement between the bolt and the spacer. When used as a clamp, the spacer, shank, expander and blocking means cooperate to deform the expander into a blind side flange and to clamp a work piece between the flange and the spacer. To remove the clamp, the bolt is moved away from the spacer while rotating the bolt in the expander to bring the external threads of the expander into threaded engagement with the internal threads of the spacer. This permits the extraction of the bolt from the blind side expander by maintaining rotational restraint of the expander with the spacer. In several embodiments, a compression spring is positioned between the head of the bolt and the spacer to automatically move the bolt when it is rotated in a loosening direction.

  • Publication number: 20100276857
    Abstract: A sleeve is positioned over a radially-expandable rod assembly and a stent is positioned over the sleeve. A mandrel is inserted into the rod assembly to thereby press the sleeve against the inner surface of the stent and expand the stent. A coating (such as a solvent, a polymer and/or a therapeutic substance) is then applied to the outer (abluminal) surfaces of the stent, by spraying, for example. The sleeve advantageously prevents the coating material from being applied to inner (luminal) surfaces of the stent and also allows the coating material to be efficiently applied to the abluminal surfaces.

  • Patent number: 7748718
    Abstract: An expandable mandrel for holding a part has a shank with inclined radial slots slidably engaged by keys. The keys are coordinated by a collar which engages an extension on each key. A platen affixes to the shank of the mandrel to provide a stop that will index the position of a part mounted onto the mandrel. The platen has radial key passages to allow longitudinal movement of the keys in the slots. The platen preferably has resilient indexing nubs to engage the part. Preferably, the position of the platen on the mandrel can be adjusted by a set screw engaging one of several indexing holes or engaging a longitudinal guide track. For machining in a wet environment, the slots can be provided with longitudinal rails and the keys provided with transverse channels to remove liquid from between the keys and the slots.

  • Patent number: 7708287
    Abstract: A collet assembly that holds two disks to be processed simultaneously uses alternating pressure zones to press against the inner diameter of the disks to hold them in place in a processing machine. While the disks to be processed are typically media disks, any type of disk processing can make use of the collet assembly of the present invention. Each pressure zone includes a contact surface on a chuck blade. When a travel stroke is initiated by an actuating device (typically an air cylinder), the drawbar pulls an angled expander rearward. The expander urges the chuck blades outward. Half of the pressure zones apply pressure (via the contact surfaces on the chuck blades) to the first disk, while the other half of the contact surfaces press against the second disk, so that both disks are held securely in position.
