Abstract: A collapsible carry cot includes a base member; first and second frame members, wherein the first and second frame members together at least partially define a side or end wall of the carry cot, and wherein the first and second frame members are pivotally coupled together such that pivoting the first and second frame members relative to one another changes a height of the side or end wall of the carry cot, and wherein the first frame member is pivotally movable relatively to the base member and the second frame member is pivotally and slidably movable relative to the base member; and a securing mechanism, the securing mechanism to releasable secure the second frame member relative to the base member, such that sliding of the second frame member relative to the base member is restricted, thereby restricting pivoting of the first frame member relative to the second frame member.

Abstract: A chisel scabbard (10) comprises a pouch (12) and a belt clip (22). An insert (14) is received in the mouth (16) of the pouch (12) and is adapted to receive various sizes of chisel. A flat front surface (64) is provided with abrasion material to permit sharpening of the chisel. Clips (50) enable two scabbards to be connected together. A sharpener (90) is provided comprising an abrasion plate (110) mounted in a slider (100). The chisel displaces the plate in the slider on insertion of the chisel in the scabbard. The slider can be actuated to repeat the sharpening stroke. The pouch (12) can comprise two extruded sections (92, 94) and end caps (96, 14?).

A flat front surface (64) is provided with abrasion material to permit sharpening of the chisel. Clip-means (50) enable two scabbards to be connected together by insertion of the clip-means (50) into a female clip receptor (52) on the front of the scabbard. A sharpener (90) is provided comprising an abrasion plate (110) mounted in a slider (100). The chisel displaces the plate in the slider on insertion of the chisel in the scabbard. The slider can be actuated to repeat the sharpening stroke. The pouch (12) can comprise two extruded sections (92, 94) and end caps (96, 14′).

Abstract: Compact triaxial multioscillator configurations are based upon frames of rhombic dodecahedron and truncated octahedral shapes as taught by U.S. Pat. No. 4,795,258. Three non-planar cavities, each comprising four intersecting bores, intersect within the frames. External Faraday rotator assemblies comprising reverse mirrors and associated permanent magnets in differing configurations eliminate the need for intracavity elements to obtain nonreciprocal splitting. In the rhombic dodecahedron-shaped frame, external Faraday rotator assemblies are fixed to three planar faces at each of which pairs of segments of each of the internal nonplanar cavities converge. In the truncated tetrahedral frame, a single external Faraday rotator assembly is fixed to the single planar face at which pairs of segments of the three nonplanar cavities converge in a pattern forming the apexes of a centered equilateral triangle.
