A pedestrian bridge includes side, bottom and rail members formed of extruded aluminum box beams welded along edges to define a U-shaped bridge having lights in a longitudinal cavity in the rail members; a second embodiment is in the form of a close pipe of irregular hexagonal cross-section.

A bridge for a string instrument such as a guitar is utilized to dampen flexural vibrations transferred to the instrument body while maintaining direct compressional wave coupling from strings to the instrument body.

A bridge for walking on is made from surfaces and from a handrail assigned to the surfaces. The handrail includes hollow section segments which have at least one longitudinal groove for connecting to struts, walls or the like.

Disclosed is a bridge apparatus for the relay of a frame between a wire LAN and a wireless LAN. When a frame transmitted by the wire LAN is a specific frame, a QoS middleware unit of the bridge apparatus adds a bridging request to an FIFO queue having a high priority. And when the frame received from the wire LAN is not a specific frame, the QoS middleware unit adds a bridging request to an FIFO queue having a low priority. A bridging unit performs the priority processing for the bridging reques...

A table bridge made of sheet steel. The bridge has a metal span that overlaps the tabletops and joins them like a bridge. The bridge butts up to the sides of both tables with a curved wall on the underside of the bridge that is the same diameter as the 36'' round tables. The top surface area overlaps the tops of the tables enough to disperse the downward pressure over a wide enough area to be stable. This bridge can be installed in seconds over two tables and, just as quickly can be removed if t...

A bridge is sized to span across an entire painting surface and is supported above the image by vertical spacers that adapt to vary the distance between the painting surface and the bridge. The bridge height above the image surface may be varied with the use of height adjusting supplemental vertical spacers. The bridge is made up of an upper block and a lower block, where the upper block can be temporarily separated from the lower block. Each block may include a resilient material such as a thin...

A bridge scraper is mounted on a main frame for vertical pivotal movement between a raised inoperative position and an operative position, where the bridge extends generally horizontally and is in wheeled engagement with an outer track of a dump, a scraper chain carried by the bridge extends along the bridge and in an operative position scrapes bulk material from the dump toward the main frame. A slope-breaking assembly is carried by the bridge and is engageable with the dump when the bridge is ...

A crossover or bridge for shipment as a compact unit for assembly at an installation site comprising a bridge section and a pair of stairways for connection with opposite ends of the bridge section. The bridge section is disposed in an elevated position relative to bottom ends of the stairways when assembled therewith for spanning an object. The bridge section comprises a pair of transversely spaced crossover panels with a grating or decking carried thereon. Readily assembled joint means are pro...

A bridge which has a bridge deck constructed of corrugated checkered metal plate and which is supported by a plurality of side-by-side box beams carried by spaced apart beam supports. The box beams have upright sides which are connected to upper and lower chord plates all of which are constructed of corrugated plate having corrugations which run parallel to the length of the box beams and which have a large, e.g. 16 .times. 6 inch corrugation pitch and depth. The chord plates and sides are bolte...

A bridge circuit provided with an isolation transformer having four primary windings which are connected such that the voice currents do and the supply currents do not generate a resulting flux in the core of the transformer and which comprises two transistor circuits. These circuits on the one hand prevent the flow of voice currents via a supply source connected to the bridge and on the other hand balance the bridge circuit so that the influence of longitudinal noise signals which are produced ...
