Disclosed is a system for telephones by providing an improved and streamlined user experience and enhanced fail over mechanisms. A decentralized system managed through a web site which allows for continued operation even when the primary systems fail includes a mechanism for restoring the primary systems automatically when they become available again. Phones connect to two PBX systems at the same time, one local and one at a remote location. The two PBX systems synchronize configuration data and media files between them. The website can also be used to manage any number of systems allowing any size organization to manage every phone system in their organization from a single interface.

A cable management and distribution system comprises posts and beams. The posts may be one of several heights to accommodate various office layouts. The beams run between the posts and a cable entry slot runs the length of each beam to allow cable entry at any point along the beam. The beams further provide space for running and storing cables and fixed power outlets may be attached to the beam interior for plugging power cords. A lift off cap may be positioned over the beam, or a bridge may be positioned above the beam to provide a separate path for data cables. The bridge includes an upper face with a mounting surface for a privacy panel or the like, and accepts plain vertical side covers, or vertical side covers with accessory tracks. The posts include lower mounting points and the beams include upper mounting points for modesty panels.

A fuel cell gasket assembly for use in conjunction with a fuel cell stack by placing the gasket assembly between the periphery of a face of the stack and a manifold. The periphery of the stack face includes periphery portions that expand differently during operation of the stack. The gasket assembly comprises a member adapted to have different compressibilities over predetermined portions of the member and/or a resilient shim embedded in preselected sections the member whereby the gasket maintains contact with the periphery of the stack face and the manifold. The structure of the gasket assembly of the present invention provides a compliant fuel cell gasket assembly that accommodates bipolar plate growth and end cell growth in the fuel cell stack and maintains the gas seal between the stack and manifold structure.

Shed formation on a weaving machine (2), which is driven by a main motor (3), with a shedding device (4), which is driven by a shedding motor (5), wherein in each motion cycle (N) of the weaving machine (2), a loom shed (7) formed by warp threads (8) of the weaving machine (2) is opened and closed dependent on a weave pattern, and wherein the synchronicity of the two motors (3, 5) is controlled by signals (10) of a control device (9). During a partial number (Tn1, Tn2) of motion cycles (N), the synchronicity of the two motors (3, 5) is changed in such a manner so that plural shed closure angles (FSW) at which the loom shed (7) in the respective motion cycles (N) is closed, form an increasing or decreasing sequence.
摘要:
A fuel cell stack compression system in which a spring assembly and mechanical linkage assembly are used in conjunction with tie rods and tie bars to apply a compressive load to a fuel cell stack. The linkage assembly includes a lever and three pins to redirect the force or movement generated by the spring assembly into a movement or force for the tie rods. The tie rods, in turn, connect to the tie bars which span the top end plate of the fuel cell stack and transfer the load to the stack. The linkage also includes a slotted bearing which compensates for the circular arc formed by the lever and allows the spring assembly to be rigidly mounted under the bottom end plate. The spring assembly comprises multiple springs arranged in parallel and designed to provide a non-linearly decreasing load as the stack compresses due to cell consolidation. This load profile reduces overall stack shrinkage while providing high pressure at the beginning of life to insure proper cell-to-cell contact.

A shutter mechanism comprising an aperture through which ambient light is passed to cause a film exposure, a pair of shutter blades supported for pivotal opening movement in opposite opening directions away from one another to uncover the aperture to permit ambient light to pass through the aperture and for pivotal closing movement in return closing directions towards one another to re-cover the aperture and supported to allow them to be pivoted simultaneously in the same direction to cause accidental shutter opening when a physical shock is applied to the shutter blades in the opening direction of one of the shutter blades, is characterized in that each one of the shutter blades completely covers the aperture in order that both of the shutter blades must be removed from the aperture to uncover the aperture to permit ambient light to pass through the aperture, and a single fixed stop is positioned between the shutter blades to prevent either one of the shutter blades from pivoting in the same direction as the other shutter blade to uncover the aperture when one of the shutter blades is pivoted in its opening direction, whereby when one of the shutter blades is pivoted in its opening direction because a physical shock is applied to the shutter blades in that direction the fixed stop prevents the other blade from pivoting in the same direction to cause accidental shutter opening.
