An adjustable connection between a ski and its binding, comprising an elevated platform that is attached to the ski at two longitudinally spaced points by supports that allow the ski to flex between the supports. Mounted on top of the elevated platform is a boot plate, to which the ski binding is attached. The boot plate is attached to the platform by screw connections that allow for rotation of the boot plate about a vertical axis, or for translation in the fore-and-aft or lateral directions. T...

An alarm or signalling system between a transmitter station and a receiver station either or both of which may be in motion. A signal is selectively radiated from the transmitter station for detection at the receiver station. The receiver station includes processing means for responding to the received signal and producing a new signal indicative of selected physical relationships between the transmitter and receiver stations during the period of signal transmission and reception. The modified s...

An electrical conductor connection between at least two aluminum conductors which includes a weld nugget having a substantially cylindrical cross-sectional configuration perpendicular to the major surfaces of the aluminum conductors. The ends of the weld nugget are convexly cupped and extend outwardly past the major surfaces of the aluminum conductors to provide visual verification of joint integrity. The electrical conductor connection is formed by a method which includes providing an aperture ...

The invention concerns a wall remaining tight despite possible displacements of its panels because of the terrain. To this end, it involves joints formed of cylindrical parts 2 and 3, connected by a band 6 consisting of at least one fold 7, of such a kind that the allowed displacement of the panels 16 and 17 entails a deviation less than the length of the unfolded band 6. The invention applies to all tight walls.

A technique for providing interconnections between pairs of contact points associated with a conductive line pattern by the use of an interconnection defining tool which is selectively alignable with respect to the conductive line. The conductive line pattern comprises at least one conductive line which is either continuous or shows interruptions, and from which lines branch off to the contact points. The tool is adapted to the conductive line and consists of a row of elements, the distance betw...

Effective, simple, easily assembled joints between adjacent ends of structural members such as stress-skin panels may be constructed by shaping the ends of such members so that they can be fitted together. Each of such structural members has a core located between two side members. The disclosed invention relates to identically shaping the interfitting ends of such members so that the cores between the side members include sloping walls spaced from the side members by spacing walls. One of the s...

A T-joint includes a frame extending along a longitudinal axis. A rung has at least one cavity and at least one cavity wall. The at least one cavity wall is parallel to the longitudinal axis. The rang has at least one fill opening. At least one T-joint part is fixedly connected to the frame. The at least one T-joint part extends into the at least one cavity. The at least one T-joint part is mechanically connected to the rung and is glued to the rung. The at least one T-joint part has at least on...

Disclosed is a device for detecting a displacement between patterns comprising a picking-up device, first and second memory means for storing a first and a second patterns picked up by said picking up device, means for shifting said first and second patterns relative to each other thereby obtaining a correlation value for each shift between them, means for obtaining a maximum correlation value and deriving a displacement in terms of the number of shifts which gives said maximum correlation value...

A mechanism to transfer small flat workpieces (chips) between locations has a pair of interlinked four bar mechanisms one of which mechanisms carries a chip spreading means operated by two cams so that the chip pickup and release means moves in substantially vertical and horizontal timed relation to pickup a number of chips, move through a shallow horizontal arc, simultaneously spread the chips further apart, drop the chip; and repeat. Mechanism is disclosed for moving a plurality of chips of bi...

The invention resides in a flange joint for use in the assembly of pipings from pipe elements. A fixed sealing flange is welded to each of the opposite ends of two adjacent pipe lengths and/or pipe fittings. Each sealing flange has two annular concentric contact surfaces on the back thereof separated by one relatively deep and broad circular groove in said back, or by a number of relatively deep but narrow annular concentric grooves. A loose flange is threaded on to each of the opposite ends of ...
