A system for connecting panels in adjacent edge-to-edge relationship comprises plates mounted to the edge of each panel providing a series of spaced-apart protuberances along each panel edge. Each protuberance includes an opening normal to the edges of the panels. A channel connector has a web which is interposed between the panel edges and includes a plurality of windows providing gateways through the web for the protuberances when the panels are placed in adjacent edge-to-edge relationship. Ea...

An edge sharpener, in particular for sharpening the steel edges of skis, is composed of a main body in which there is a recess for holding a file blade and within which is inserted a clamping wedge so as to exert distributed forces on the surface area of the file blade when the clamping wedge is forced into the recess substantially radially. In a particular feature of the invention, the main holder has a flexible foil which comes to lie between the pressure surface of the clamping wedge and the ...

Apparatus for cutting and notching T-edging comprising male and female notching die members, pneumatic means for moving the male die member with respect to the female die members, an axially movable cutting blade for severing the T-edging, an air cylinder for actuating the cutting blade, and guard means enclosing the cutting blade.

An edge connector for a printed circuit board includes a housing detachably secured to a plurality of contact elements. A conductor is provided within the housing to form a transmission line with the contact elements. The transmission line thus formed has a characteristic impedance equal to that of the circuitry associated with the respective contact elements. Cam surface projections are included which shift the contact elements beyond the insertion path of the circuit board in response to the i...

The inner edge of a roll of sheet steel or similar element, which is secured by a tiedown chain, is protected by an edge protector positioned between the element and the chain. The edge protector comprises two plates joined at a right angle and having a contour at the junction conforming to the edge of the element being protected. The plates have ribs to hold the chain on the edge protector.

Steel edge, particularly for skis made of a synthetic resin, consisting of a profiled strip fixedly connected with the body of the ski, which strip essentially corresponds to the length of the ski edge, is flat along its underside, and is flush with the sole of the ski, characterized in that substantially vertical extensions emanate from the profiled strip, these extensions being arranged at a spacing from the outer rim of the strip and being anchored in the underside of the ski body by the use ...

An electrical contact for use in a printed circuit board edge connector comprises a pair of channel cross-section arms each providing a pair of contact surfaces for engaging a board mated with the contact, the arms being relatively rigid and thus providing high contact pressures.

A trim strip of U-section for a marginal edge of an automotive body panel or the like comprises a flexible but relatively stiff core member of U-section formed of metal and having a plurality of longitudinally spaced transverse slots to permit the strip to deform in conformance to the contour of the panel edge. A flexible plastic decorative covering is secured to the core in overlying relation but is outspaced therefrom except along oppositely spaced marginal edges. In a modification a core memb...

A pair of panels defining, with a connecting strip, a channel for receiving a marginal portion of a sheet of glass.

A ski edge has an undercut or hollow forming an inner wall providing greater control and edge grip while skiing particularly on hard snow or ice when executing a turn or stopping. The undercut also provides an edge which retains its grip or "bite" by remaining sharp many times longer than conventional edges.
