Abstract: A fall protection system having two telescoping supports positioned at either end of a job location and having a crossbar extending there between that allow a user to work in an elevated position while also providing a tethering point to protect against falls. The supports may be coupled to a pair of conventional ladders that support a walk board, or the supports may directly support a walk board extending between the two supports. The two supports retain and securely attach to a horizontal support beam that is the anchoring location for a fall protection harness. A user may then use the walk board to perform installations or repairs above the minimum height necessary for fall protection and be secured against a fall by attaching via a harness and strap to the cross-bar.

Abstract: A fall protection system having two telescoping supports positioned at either end of a job location in combination with conventional ladders. The two supports retain and securely attach to a horizontal support beam that is the anchoring location for a fall protection harness. The two supports may also be laterally interconnected to the two ladders, which may additionally support a conventional walk board via ladder jacks. A user may then use the walk board to perform installations or repairs above the minimum height necessary for fall protection and be secured against a fall by attaching via a harness and strap to the cross-bar.

Abstract: A longitudinally driven slotted transducer has a tubular member with an axial slot extending from one end to the other end. A drive assembly is disposed across the inner wall of the tubular member and supported by journal bearing surfaces extending from opposing sides of the inner wall to locate the drive assembly in a position offset from the longitudinal central axis of the tubular member. The interface between the drive assembly and tubular member comprises a layer of solid lubricant material mounted on the journal bearing type surfaces.
