Abstract: A compact self-aligning transceiver for high bandwidth cooperative duplex communications, laser image projections or surveillance applications comprises a base mounted hermetic transparent sphere encapsulating a system of two or more pancake motors, two of which are being nested and orthogonal to each other to suspend and rotate a system of optical components centrally located within said motors for receiving and selectively transmitting radiation beams.

Abstract: A combination tool chest dolly and leaved workbench comprising a frame having generally parallel and spaced-apart first and second side members joined by a plurality of cross members and a plurality of support legs perpendicularly disposed from the frame. A plurality of casters are retractably mounted to the frame. The casters are movable between a first position thereof in which the frame is supported by the legs and a second position thereof in which the frame is supported by the casters. A plurality of generally parallel and spaced-apart stanchions having upper and lower ends are secured adjacent to the first and second side members at the lower ends thereof. At least one work surface leaf is swingably mounted between the upper ends of a pair of stanchions secured to the first and second side members, respectively, at the upper ends thereof.

Abstract: A scaffold structure comprising a pair of leg frames and a support frame. The support frame includes a pair of posts vertically slidably received in the leg frames and means for locking the same thereto at selected elevations. The support frame includes telescopically engaged members whereby it can be extended or contracted and locked to provide a support of different lengths.
