Appl. No.:

09/610071

Inventors:

Yu Lin - Blue Bell PA
Daniel C. Ziegler - Millersville PA
William J. Platt - Aston PA

Assignee:

Worthington Armstrong Venture - Malvern PA

International Classification:

E04B 906

US Classification:

5250607, 5250606, 5250608, 522206

Abstract:

A compression relief section in a beam in a grid for a suspended ceiling that permits controlled collapse of the section during a fire, whereby the ceiling is kept relatively intact. The section has a channel formed from the web portion of the beam, and a crushed bulb with a hump, along with a flange, that fold from compression forces, while resisting such forces. There is no interference between the folding portions and the ceiling panels, or drywall, when the section collapses.

International Classification:

E04B 200

US Classification:

5250606, 5250602, 5250608

Abstract:

An end-to-end connection for main beams in a ceiling grid for a suspended ceiling. A connector is formed at the end of a beam by combining a clip, fastened to the beam, with a configuration in the end of the beam. The connections are engaged to form a connection. The connection can be disengaged and reengaged.

US Classification:

52232, 5250607, 525731, 52664, 52DIG 5

Abstract:

The invention relates to a right-angle connection in the grid of a suspended ceiling, between inverted T-beams having a vertical web extending between a bulb at the top and flanges at the bottom. A connector on the end of a cross beam hooks into a slot in the web of a main beam. The connector has a plastic encasement that forms abutments about a metallic core. The abutments position the connector within the slot in the web, and prevent further entry of the connector into the slot, under normal conditions. The plastic abutments melt away during a fire, so that the beam can expand longitudinally into the slot to relieve stresses in the beam, without the beam buckling. Ridges on the bottom of the metallic core that engage the web at the bottom of the slot, prevent pullback of the connector from the slot, during a fire, to prevent the ceiling from sagging or drooping.

US Classification:

5250606, 5250608, 5250607, 525061

Abstract:

A V-shaped indent is formed in a stab-in connector for a suspended ceiling grid. The indent forms a vertical bend line. In a fire, the connector bends along the vertical bend line to permit a cross beam in the grid to expand while keeping the grid intact, and thus capable of continuing to support the panels.

International Classification:

E04B 9/10
E04B 9/34

US Classification:

5250606, 5250607, 525061, 5250609

Abstract:

A stab-in connector that locks with an opposing identical connector, through a slot in the main beam of a suspended ceiling grid. The connector has a straight locking latch that is cantilevered from a bend at a base of the connector. The bend is in the form of an arc. The bend forms a pivot for the latch. Contact between the cantilevered straight locking latch and the side of the slot is delayed as the connector is being stabbed into the slot. During the delay, the connectors are positioned within the slot, and relative to each other, so that substantially less force is needed than the force that was necessary to engage prior art stab-in connectors into locking position.

US Classification:

707752, 707722, 707758, 707769

Abstract:

The method for providing a data context service involves extracting context information from a host application associated with an oilfield project, the context information includes a current state of a user in the host application, sorting the context information into multiple dimensions of relevance, generating a search profile for each of the multiple dimensions of relevance, requesting a first set of searches using at least the search profile, receiving oilfield data items resulting from the first set of searches, obtaining a quality measure of an oilfield data item of the oilfield data items based on a pre-determined quality criterion, sending the oilfield data item as a search result to the host application after determining the quality measure exceeds a pre-determined threshold, and generating an output using the host application based on the search result, the output being used to perform an oilfield operation.

International Classification:

A61B 1756

US Classification:

606 88

Abstract:

A patella clamp and method for use in resecting a patella for the reception of a patellar prosthesis holds the patella in a preparation position and provides the surgeon with a direct and interoperative accurate visual indication of the bone thickness of the patella prior to and subsequent to resection, as well as a direct and interoperative accurate visual indication of an interoperatively settable depth of resection, all without the necessity for introducing supplemental instruments or other apparatus during the resection procedure.
