Abstract: Provided herein is a quick disconnect torch handle for use in a plasma arc system. In one approach, the plasma arc system includes a lead having a first end connected to a power source and a second end connected to a torch handle. The quick disconnect is located at a proximal end of the torch handle, and may include at least one signal connection, a pilot connection, a fluid connection, and a main power connection. The fluid and power connection may be formed by a connection between a main power socket and a conductive conduit. Specifically, the main power socket includes a conductive spring and an O-ring encircling an interior bore thereof. Removal of the conductive conduit from the main power socket causes the fluid connection to break between the O-ring and the conductive conduit, and then the power connection to break between the conductive spring and the conductive conduit.

Abstract: A telescopic support assembly including tube assemblies and bearing assemblies. The tube assemblies are arranged telescopically from a largest cross section rear tube assembly to a smallest cross section front tube assembly. The bearing assemblies include a non-roller bearing for each tube assembly other than the front tube assembly. Each bearing assembly is configured to present a surface of the non-roller bearing at the bottom interior of a tube assembly, proximate the front of the tube. Some embodiments include a drive assembly for extending and retracting the telescopic support assembly.

Abstract: Systems for wall sections, wall panels assembled from sections, walls assembled from panels, and shelters assembled from walls. In embodiments, a wall for a shelter is disclosed, the wall comprising a frame comprising frame segments forming an n-sided closed polygon; at least one wall panel, each wall panel contained within the frame; and a plurality of flats, each flat attached to and overlapping a frame segment and a portion of a wall section, thereby retaining each wall panel within the frame. In embodiments, a shelter is disclosed, the shelter comprising a plurality of walls, each wall comprising a frame comprising frame segments forming an n-sided closed polygon; at least one wall panel, each wall panel contained within the frame; and a plurality of flats, each flat attached to and overlapping a frame segment and a portion of a wall section, thereby retaining each wall panel within the frame.

Abstract: A composite panel construction suitable for use in furniture, and particularly for uses such as table, desk and cabinet tops includes, in a first embodiment, a single honeycomb layer sandwiched between a pair of plywood layers, with the honeycomb layer preferably made of polystyrene or a similar polymeric material. In a second embodiment, a composite panel includes a single plywood core with upper and lower honeycomb layers attached above and below the single plywood core. The plywood layers in both embodiments provide resistance to screw pull-out such that screws can be threaded into the panel from any desired position on the bottom of the panel and the exposed edges of the plywood layer(s) provide adequate surfaces for the attachment of decorative edging material to the panel.
