Abstract: A backscatter measurement device for measuring the thickness of a coating on elements forming a web of substrate material moving from a feed supply to a take-up location at a predetermined speed. A measurement wheel is provided, adjacent to the rim of which is mounted a backscatter probe for irradiating and detecting the backscattered radiation from a coated substrate. The web of substrate material is threaded around the outer surface of the rim. The measurement wheel is rotated at a speed such that the tangential speed of a point on the rim equals the speed of the moving web whereby the probe and an adjacent point on the web are stationary relative to one another while the point on the web is adjacent the rim. Thus thickness measurements may be taken without stopping the movement of the coated web. This backscatter measurement device is further provided with indexing apparatus to position automatically the probe directly adjacent an element to be measured on the web.

Abstract: An orthopedic device for use as a "walker" for the aged or infirm. The orthopedic device having a tripod frame mounted on a U-shaped base element. Attached to the tripod frame are adjustable crutch-like shoulder support members and hand grips together with an adjustable seat for custom fitting the "walker" to the person. The seat is capable of moving downward and away from the user to permit the user to easily step in and out of the "walker".

Abstract: Pressure sensitive magnetic image transfer media in the form of a thin film substrate having a thin layer of solvent evaporated residue of a liquid mixture incorporating substantially equal dispersed amounts of polyethylene homopolymer and magnetically sensible material with small amounts of mutually incompatible dissolved acrylic film forming resin material and ethyl hydroxyl ethyl cellulose.

Abstract: A game board for adversary move and countermove type games in the form of a cube presenting six playing surfaces each including a plurality of holes arranged in a rectangular matrix pattern of not less than three by three nor more than five by five holes therein, each of said holes being adapted to releasably retain a manually displaceable pin member thereon.

Abstract: A sport shoe construction of the type where a shell edge band peripherally overlies at least a portion of the marginal edge of the shoe outersole and the adjacent marginal edge portion of the upper shaft material, the incorporation of a plurality of mechanical gripping members operatively embedded in said upper shaft material and the interfacially abutting portion of said shell edge selectively positioned to mechanically restrain downward movement of said shell edge relative to the interfacially abutting portions of the shaft material.

Abstract: Thaw-indicator for frozen articles including a V-shaped transparent elastomeric tube having its inner wall surfaces disposed in liquid tight interfacial engagement at the apex of the V by a removable band and defining a pair of closed liquid containers, adapted to contain freezable contrasting liquid dyes.
