Abstract: A connector for detachably joining one profile section to another in a framework assembly comprises a housing having a bottom part and a lid connected to one another by means of snap-lock coupling elements. The housing is insertable into a longitudinal recess at one end face of a horizontal profile section. A latch is slidably disposed in the housing and has, at an end projecting from the housing, a hook for engaging an inwardly facing surface of a vertical profile section. At an end opposite the hook, the latch has a rectangular aperture traversed by a substantially cylindrical eccentric pin projecting from the housing of the connector into a transverse bore in the horizontal profile section.

Abstract: A tensioning and anchoring device for fence cables including spaced upstanding posts anchored in the ground and having cables arranged therebetween including a stress distributing assembly employing a plurality of coil tension springs, one mounted around the free ends of each of the cables. The springs are positioned in a bracket between a fixed side thereof and a movable bar to which the free ends of the cables are attached, which bar applies a resultant substantially equal force to all of the cables.

Abstract: A connector for joining a fiber optic cable. The connector is constructed th a thin wall tube enclosing strips of a shape memory alloy material. The strips are bent and inserted into the thin wall tube such that an axial cavity is formed between the opposing strips. The axial cavity provides a self-centering mechanism for positioning fiber optic cables along the central axis of the tube. Dimensions of the tube and shape memory alloy strips are chosen such that fiber optic cables inserted into each end of the connector when it is above the transition temperature range of the strips will be forced into coaxial alignment when the connector is cooled to a temperature below the transition range of the strips.
