Abstract: An interlocking connector system includes two connector members that can each be mounted to separate objects and then interlocked together to attach the two objects together. In one embodiment, the two connector members are identical and interchangeable with each other. In other embodiments, the two connector members are arranged to attach together objects having perpendicular mounting surfaces or coplanar mounting surfaces.

Abstract: A joint structure has a male-side metal joint (3) fixed on a column (1) and a female-side metal joint (4) fixed on a beam (2). The two metal joint (3, 4) are common joints having the same shape, and have a first contacting surface (81), a second contacting surface (82) which continues from the back thereof and curves upward at an angle of less than 90.degree., and a third contacting surface (83) which continues from the front of the first contacting surface and curves downward at an angle of 270.degree. or more. When one of the two metal joints (3, 4) is put on the other, these contacting surfaces contact intimately with each other. If the two joints are fastened by a fastening bolt (5) in this state, the beam (2) is jointed to the column (1). Because the first to third contacting surfaces (81 to 83) incline, the joint metals (3, 4) do not get out of place longitudinally or vertically. Hence the simple subsequent operation of fastening and so forth can be carried out easily.

Abstract: A downhole motor includes a bearing unit connected to a moving section incorporating successively arranged working members--a stator and a rotor interacting with each other along profile surfaces. The like pairs of the adjacent working members are rigidly connected to each other by means of solid threaded bushings. A mounting fixture includes two mounting elements each made as two bushings interconnected by a coupling, the bushings having their profile surfaces located on the same longitudinal axis. One of the bushings is rigidly connected to the coupling, while the other bushing is mounted with the possibility of moving with respect to the longitudinal axis. A method of assembling the downhole motor is effected with the use of a pre-adjusted mounting fixture and resides in interconnecting the like working members by thread bushings ensuring the arrangement of the profile surfaces of the working members analogously to the profile surface of the single monolithic rotor and stator.

Abstract: The invention provides a releasable connector comprising a male part presenting four mutually inclined faces forming a tetrahedral wedge, and a female part presenting three walls for mating with the faces of the male part when the male part is inserted therein. A locking device is mounted on one of the two parts and applies a locking force, urging the wedge into intimate contact with the female part to lock the male part in position. The locking means is movable to a release position in which it frees the male part for insertion and withdrawal in a direction transverse to the face. The mutual inclinations of the three faces are sufficient to avoid jamming of the connector.
