Abstract: A loom harness having nested pairs of cylinders. The pairs of cylinders are arranged in parallel fashion and offset in relation to one another on a rigid, stationary frame. Pillow blocks spaced along the frame support the cylinders. Flexible cables, connect the pairs of nested cylinders and support heddle eyes at their approximate midpoints. Alternatively, the cables can support heddle frames which, in turn, carry wire heddles. Control cables are attached to the upper and lower cylinders, and are moved upwardly or downwardly by a dobby. An alternative control includes an A-C servo motor and drive shafts to move the cylinders. The selective rotation of the various pairs of nested cylinders causes the translation of the heddle eyes. This movement of the heddle eyes causes a shed to be created in the warp yarn passing through the eyes.

Abstract: A center brace apparatus for a loom frame or harness that extends between an upper and lower elongated frame members. One or more center brace members extend between the elongated frame members in abutting relationship therewith and are clamped to an associated frame member for a quick and simple installation and release. The center brace member is an elongated member that has T-shaped end or foot portions that abut surfaces on the elongated frame members. On each of the frame members is a clamping assembly that includes a hollow support bracket member with top, bottom and side walls. A sliding block member is disposed inside of the hollow bracket support member for sliding contact with side walls of the support bracket member. A screw member is received through one wall member and threadedly engages the slidable block member through a threaded opening in the slidable block member for moving the block member toward and away from the center brace member.

Abstract: A microwave energy transmission system for coupling a stationary waveguide to a rotating waveguide including a transition coupling assembly comprising a plurality of equal length transmission lines having their opposite ends terminating in annular patterns defining equidistantly, circumferentially spaced regions of maximum coupling, and a pair of rotatable horns having flared apertures sweeping circular paths in gapped registry with the annular patterns and spanning, at any instant, a plurality of said regions.

Abstract: A feed system for a geodesic Luneberg lens antenna system is disclosed, in which sequential cyclical scanning of a plurality of feed sectors of the lens from one transmitter/receiver is achieved with a minimum of dead time between successive scans.
