A closing mechanism for a capping machine for closing bottles via crown caps or similar closures. The closing mechanism is disposed over a bottle support and, in a vertical axis, can be lowered out of a starting position and returned thereto. A deformation member is provided for placing a closure upon the mouth of the bottle and for subsequently fixing the closure thereon via deformation of the closure while simultaneously pressing the closure against the mouth. A hold-down mechanism extends cen...

An improved self-capping disposable needle assembly for use in combination with a skin puncture apparatus is provided. More specifically, an improved self-capping disposable needle assembly for use with a catheter which assembly contains a pleated sleeve made from any natural or synthetic fiber material is provided. The fiber materials employed as the pleated sleeve optionally may be treated with a suitable agent that provides the fiber material with a hydrophobic coating and prevents fluids suc...

Acoustically thin capping structures and acoustic droplet ejectors having fluid wells and which use such capping structures to create fluid cells. The inventive capping structures permit the accurate positioning of the free surface of a fluid, permit acoustically induced fluid droplet ejection, and prevent fluid from spilling from the fluid wells. "Acoustically thin" means that the thickness of the capping structure is small enough that the acoustic energy that is lost passing through the cappin...

The present invention provides a process for the capping of a living polymer with one or more capping compounds comprising non-polymerizable monomer, preferably selected from the group consisting of substituted or unsubstituted diphenyl alkylene, substituted or unsubstituted .alpha.-methoxystyrene, substituted or unsubstituted trans-stilbene, substituted or unsubstituted 1-isopropenylnapthalene and substituted or unsubstituted 2,4-dimethyl-.alpha.-methylstyrene.

A straight line capping machine is provided that wherein the cap tightening discs and the container grasping mechanism are synchronized to a predetermined relationship so as to prevent cocked caps, loose caps and/or scuffed caps. In particular, the mechanisms are synchronized to ensure that the tangential velocity of the rear cap tightening disc minus the tangential velocity of the front cap tightening disc is about twice the predetermined velocity of the container passing through the capping ma...

A method and structure for forming a metallic capping interface between damascene conductive wires/studs and damascene conductive wiring line structures. The method forms a first insulative layer on a substrate layer, followed by forming damascene conductive wires/studs in the first insulative layer. A lower portion of each damascene conductive wire/stud is in contact with an electronic device (e.g., a field effect transistor), or a shallow trench isolation, that is within the substrate layer. A...

The present invention provides a process for the capping of a living polymer with a substituted or unsubstituted diphenyl alkylene. Diphenyl alkylene is defined to also include substituted or unsubstituted .alpha.-methoxystyrene, trans-stilbene, 1-isopropenylnapthalene and 2,4-dimethyl-.alpha.-methylstyrene.

The present invention provides an ink ejection type printhead assembly including a capping device movable between an open position, in which the printhead may deposit ink on the surface, and a closed position, in which the capping blocks the printhead from depositing ink. The capping device is being mounted for rotation about an axis parallel to a first direction, the direction that the printhead ejects ink.

A capping mechanism for a print engine includes a capping member mountable in alignment with a printhead of the print engine. The capping member is displaceable into and out of abutment with the printhead for capping and uncapping the printhead respectively. A torsion bar arrangement acts on the capping member for displacing the capping member. A mechanical displaceable element co-operates with the torsion bar arrangement such that, when the element is in a parked position, the element engages t...

The present invention involves a hand-held capping device for surgical needles designed to minimize the risk of accidental needle punctures, characterized by a conical, rimmed shield tapering to a tubular section, a socket being formed at the juncture of the shield with the tubular section in a configuration to receive and grip the hub portion of a conventional surgical needle assembly. The device may include mechanisms to effect needle assembly ejection and/or accommodate assemblies of varying ...
