A connection between two components (2, 3) comprises an extension (5) from one of the components (2) which passes through a hole (6) in the other component (3). The extension (5) is formed from a plastics material having a memory ability and has a tubular shape. The edge of extension (5) is rolled over outwardly and backwardly towards the other component (3) and contacts it. A process for connecting the two components and a tool (9) for carrying out this process are also disclosed.

A joint between structural members such as edge members of panelled furniture, the joint being secured by a bracket having leaves which each abut and are secured to one of the structural members. The leaves each have an axis and the axes intersect to define a plane, the faces of the leaves abutting the structural members being obliquely inclined to that plane.

Joints are provided between the members of a pair of elements, such as a pair of concrete tunnel lining segments which are secured together in compression by a fastening arrangement with a gasket between the end faces of the segments. The gasket has a multiplicity of spaced recesses or apertures to prevent the gasket from creating a surface tension in the end faces when the joint is subjected to compression.

A releasable coupling between a shaft and a hub is provided, which coupling includes a device operable by a pressure medium to produce a pressure lack between the shaft and the hub.

A nut in combination with a deformable plastic plug is provided so as to produce a torsional reistance when the nut is screwed onto a similar male thread such as a bolt. The plug comprises an inner core wedge and an outer sleeve which will expand upon insertion of the core. The sleeve is placed into the nut, leaving at least one complete turn of the thread free, and the core is wedged into the sleeve forcing it to deform into the thread.

Discrimination between sidelobe and main beam reception of interference signals in a lobe on receive only radar is accomplished by a method of operation in which interference signals are stored and averaged for the radar receive beam positions of boresight, up, down, left and right. Interference signals received at boresight are compared with interference signals received at each off-boresight beam position. Interference signals received at boresight are also differenced with interference signal...

An electrical motor has one or more capacitors inside the motor. Particularly, a half-pitch capacitor induction motor is shown, wherein the stator winding has a plurality of coils, one each on a tooth of the stator, and an auxiliary or capacitor winding includes a plurality of coils, one each on different ones of the teeth of the stator. The stator coils are spaced around the periphery of the stator such that spaces are provided between the coils, and one or more capacitors are provided in such ...

A drive between an autoleveller output and a coiler in a carding and deposition assembly comprises slack take-up means, and means for varying the length of the sliver path. In a belt drive, the slack take-up is effected on both sides of the belt drive by dancing pulleys. These may be resiliently biassed, either by a helical tension spring, by the belt elasticity and pulley geometry, or other suitable means.

A storage device for use between exposed rafters of a basement or like ceiling is disclosed. The device includes a base and drawer each of rigid welded wire construction. The base is secured by wood screws to the bottom surface of adjacent rafters to span between them. The base includes tracks in the form of welded wires which define a pair of parallel slots. The wires also define an enlarged opening into the slots of the front end of the base. The drawer at the bottom of its rear end has a pair...

In a connection between a pipe and a molding, a tubular housing, fixed on the molding, engages around the pipe with an inner wall tapering conically toward the free end of the housing. Arranged between the pipe and the housing inner wall is a clamping ring, which braces the pipe with the housing in a wedge-like manner. The clamping ring is held in its wedging functional position by a spring element acting on it in the axial direction. The spring element can be locked in a prestressed state witho...
