Appl. No.:

11/130529

Inventors:

William J. Platt - Aston PA, US
Yu Lin - Blue Bell PA, US

Assignee:

Worthington Armstrong Venture - Malvern PA

International Classification:

E04B 9/08
E04C 2/02

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.

International Classification:

G06F 11/00

US Classification:

370241

Abstract:

A hybrid approach to populating forwarding tables in a virtual network obtains forwarding data both by simulating routing protocol behavior in the virtual network to build forwarding tables, and by importing operational forwarding data from corresponding physical nodes in a physical network. The use of operational forwarding data improves the fidelity of the simulation by closely conforming forwarding behavior in the simulation to that which occurs in the physical network.

Inventors:

Yu Lin - McLean VA, US

International Classification:

A47K 7/03

Abstract:

An elastic sleeve method and apparatus for use with a bar of soap to limit the surface area of the soap that is exposed, and reduce the rate of shrinkage of the bar of soap. The sleeve comprises a container of elastic material having a top, bottom, and an elastic opening for insertion of a soap cake. The elastic material has form-fitting dimensions adaptable to the shape of an underlying soap cake. The elastic material also has a plurality of apertures to provide atmospheric communication through the elastic sleeve to an inserted soap cake's surface and a plurality of bristles on the bottom to enhance suds and exfoliation.
