Abstract: A corner connector (10) for connecting adjacent first and second spacer sections (20, 22), to form an insulated panel spacer frame includes a first arm (12) joined by a flexible joint (15) to a second arm (14). The second arm includes a recess (44) adjacent the joint, and a deformable projection (46) projecting from an edge of the open face of the recess inwardly toward the bottom of the recess. The first arm includes a securement projection (38) protruding from adjacent the joint (15) that is receivable within the recess of the second arm alongside the deformable projection. The deformable projection is deformed by the securement projection and exerts a compressive force on the securement projection to releasably secure the first and second arms in a desired angular orientation.

Abstract: A positioning pin of the invention is attached to an engine part for installing a gasket thereon. The positioning pin includes a body having a projection extending outwardly from the engine part. The projection includes at least one large diameter portion, and a small diameter portion about the body. When the gasket is accidentally moved on the engine part to slip out of the positioning pin, the gasket engages the small diameter portion or is blocked by the large diameter portion to prevent accidental disengagement of the gasket from the engine part.

Abstract: The invention is directed to a positive-engaging coupling between a drive part and a driven part. The positive-engaging coupling includes an insert portion defining a first noncircular cross section and formed on the driven part. The drive part defines a receptacle for accommodating the insert portion therein and the receptacle has a second noncircular cross section corresponding to the first noncircular cross section. The insert portion and the receptacle conjointly define an intermediate space when the insert portion is inserted into the receptacle. An elastic insert is inserted into the receptacle for filling out the intermediate space when the insert portion of the driven part is disposed in the receptacle. If an overload occurs, the elastic insert is destroyed and the insert portion rotates freely within the receptacle.

Such electrofusion joint and header are applicable to any part of a piping system for supplying hot water and they will withstand use for a prolonged period.

Abstract: The present invention concerns a panel with a horizontal or vertical transverse ridged cross-section, that can be interconnected in sucession with other panels of the same type to form a continuous screen which is installed above the central barrier separating the two carriageways of a road, or above the barriers that delimit the sides of a road; this screen, particularly when installed above the central barrier of a road, being designed to be capable of simultaneously acting to screen off full beam headlamps and spray from wet road surfaces from the opposing carriageways of a road, and to act as a reference at night and/or in conditions of poor visibility, due to the high refractive power of its surfaces.

Abstract: A clip provides a method for securing suspended ceiling tees to each other at an angle, especially but not necessarily at an angle other than a right angle. The clip has a body portion, an integral first tab portion projecting from one end of the body portion, an integral second tab portion projecting from the other end of the body portion, and preferably two integral tongue portions projecting from the body portion along either side of the second tab portion.

Abstract: A frictional resistance coupling comprises an outer part and an inner part, which are connected to each other in a pressure-tight manner and between them form an inner chamber with a conical surface and a likewise conical, axially displaceable annular piston. The annular piston is moved axially due to the supply of pressure medium, for producing a radial tension and frictional resistance between two parts, e.g., a coupling and a shaft. Serving for determining the axial position of the enclosed annular piston is an axially disposed transmitter cylinder, which is connected to a receiver cylinder in the region of the outer surface of the coupling, by way of an incompressible medium. The piston of the receiver cylinder supports an indicator, whereof the position is monitored by an external sensor.

Abstract: A rolling flexure bearing. The bearing is formed of a thin sheet of elastic material that is attached to a surface of a first object. The sheet extends a short distance along the surface of the first object. The sheet then makes a 180 degree elastic bend off the surface of the first object to reverse the direction of the sheet. After making the bend, the sheet then extends a short distance along the surface of the second object substantially parallel to the surface of the first object. The sheet is attached at its end to the surface of the second object.In this configuration, the flexure bearing is stiff along an axis parallel to the bend axis to constrain movement along this axis. The flexure bearing, along the axis normal to the surfaces of the objects, has a high compliance rate to provide damping between the objects. Along the third orthogonal axis, normal to the bend axis, the bearing allows free relative movement between the two objects, until it approaches either of the two attachment areas.

The present invention teaches welded, adhesive, and frictional means of joining the ornamental sections to the support member. The system of the present invention allows the user to configure the post or column in a multitude of arrangements, and is adaptable to various length support members.

Abstract: A node coupler for interlocking truss beams of a self-standing structure. The coupler includes at least one pair of diverging elongated arms.

Abstract: A connector which can separably couple a hollow first profiled member with a channeled second profiled member has an open-ended housing for a reciprocable clawed coupling member and an eccentric which is rotatable to move the coupling member between extended and retracted positions. The coupling member has a front projection which can be pushed by a disc of the eccentric to move the coupling member to extended position in which the claw or claws of the coupling member can enter a channel of the second profiled member. The coupling member further includes a rear projection which can be pushed by the disc to move the coupling member to the retracted position in which the claw or claws bear against an internal surface of the second profiled member and urge an outer side of the second profiled member against the adjacent end of the first profiled member. The rear projection is part of a looped rear end portion of the substantially plate like coupling member.
