Packaging for prosthetic heart valves including an assembly for stabilizing dry prosthetic tissue implants such as heart valves during storage. The packaging assembly includes a primary sterile barrier that permits gas sterilization of the tissue implant, and a secondary sterile barrier that also prevents oxidation of the implant during long-term storage. Tissue heart valves may be placed or suspended within a cavity of an inner rigid tray with a gas-permeable lid sealed thereon, and a cap placed over the cavity to limit movement of the valve therein. The inner tray is placed within an outer sterile barrier, such as another rigid tray or a flexible pouch, and the assembly is then sterilized. The outer sterile barrier may include a double seal so that a first gas-permeable seal can be closed for sterilization, after which a second gas-impermeable seal can be closed to seal out any further oxygen contact with the tissue implant. Alternatively, the inner tray may be placed within a sterile pouch and the assembly gas-sterilized, and then the entire assembly is placed within another pouch that provides an impermeable barrier to the surrounding atmosphere to prevent oxidation of the tissue implant.

A clamping mechanism is provided for supporting a plurality of tools for use in a folder gluer machine. The clamping mechanism includes first and second clamps. Each clamp defines a corresponding clamping cavity for receiving a tool therein. Each clamp is movable between a release position wherein the clamping cavity has a first configuration and a clamping position wherein the clamping cavity has a second configuration. A clamping structure is operatively connected to the first and second clamps. The clamping structure sequentially moves the first and second clamps to their clamping positions.

A paneling system is provided herein that concerns interconnecting panels with opposite connecting sides of substantially tongue in groove joint couplings and opposing adjacent connecting sides that are of substantially hook-joint coupling. The hook joint hinders lateral motion while permitting movement in a direction perpendicular to the plane of the interconnected panels to provide ease of installment and removal. The hook joints also provide proper alignment and spacing between panels.

An improved bassinet frame for an infant playard comprising a plurality of structural members configured to nest within a playard top frame top and rest upon supports on corner members of the playard frame. The bassinet frame includes a pair of spaced-apart, parallel side members connected by a pair of perpendicularly aligned uplift preventing end members. The bassinet frame end members extend beneath playard frame end members when the bassinet frame is deployed for use such that the playard end frame members inhibit uplift of the bassinet frame. The side members each further include a joint positioned approximately midway along the respective lengths allowing the bassinet frame to be folded along an axis parallel to its width. Folding the bassinet frame retracts the end members from beneath the playard end frame members and allows the bassinet frame to be removed from the playard.

A spring device comprising at least one annular support plate defining a ring with a central axis; a plurality of circumferentially spaced, parallel oriented coil springs disposed about the at least one annular plate; and, a plurality of lock assemblies spaced about the plate. Each of the lock assemblies being in position within a spring cavity of one of the coil springs to allow additional springs to be provided on the spring device. In addition, the lock assemblies are dimensioned so that the coil spring is retained in a prestressed condition.

Cable Support Systems for supporting an object at a desired distance below an overhead beam or other overhead structure are provided. Novel clamps for clamping to the overhead structure are fitted to support cables that encircle objects to be supported by the cable support systems. The novel clamps have internal methods to support the cables. The cables are then encircled around the objects and fixed relative to the clamp. The distances between the object and the clamps may be precisely controlled.

Each of the lock assemblies being in position within a spring cavity of one of the coil springs to allow additional springs to be provided on the spring device. In addition, the lock assemblies are dimensioned so that the coil spring is retained in a prestressed condition.

An apparatus having a mounting body, a support having a first end and a second end. The first end of the support being pivotally secured to the mounting body for pivotal movement about a substantially horizontal primary pivot axis. A rail grooming head mounted to the second end of the support.
