Abstract: Resinous polymer sheet materials having selective, surface decorative effects comprising:(1) a base layer or substrate, such as a fibrous backing sheet material and/or a blown or unblown resinous polymer composition having either an embossed or a relatively smooth surface;(2) a pattern or design printed or otherwise deposited on and adhered to the base layer or substrate, certain portions of the printed pattern or design having certain colors, and other portions of the printed pattern or design having other colors; and(3) a wear layer having an embossed or a relatively smooth surface and containing reactive polymerizable monomers and having certain surface portions provided with a certain texture or effect, such as a flat, dead or dull mat finish, and other surface portions provided with another texture or effect, such as a sleek, glossy or lustrous finish, the interior portions of the wear layer lying under the flat, dead or dull mat finish having a relatively high melt viscosity and containing relatively hi

Abstract: Methods and apparatus for applying and adhering particulate thermoplastic materials to supporting substrates, such as medallions, appliques, patches, and like goods which comprise: placing the goods on a relatively stationary support at a loading station thereof; lifting the goods from the relatively stationary support, moving them forwardly and replacing the goods on the relatively stationary support at a particulate thermoplastic materials applying station thereof; applying particulate thermoplastic materials to the surface of the goods; lifting the goods from the relatively stationary support, moving them forwardly and replacing the goods on the relatively stationary support at a heating and bonding station thereof; heating the particulate thermoplastic materials and adheringly bonding them to the surface of the goods; and disengaging or separating the goods with the adhered thermoplastic materials thereon from the relatively stationary support so that the goods are positioned forwardly beyond the heating

Abstract: A self-locking device for locking a movable member to a stationary member including a rotatable latch member mounted on the stationary member and having a pair of ears located on opposite sides of its axis of rotation, the movable member having a pair of heels cooperations with the ears of the latch member in such a way that longitudinal movement of the movable member relative to the stationary member and toward the closed position causes one of the heels to engage one of the ears on the latch member thereby rotating the latch member until the other ear engages the other heel to latch the movable member in the closed position, the face on the other ear and the face on the other heel being angularly positioned with respect to the axis of rotation of the latch member such that movement of the other heel toward the open position will not impart any substantial rotary movement to the latch member to cause it to rotate to an unlatched position, thereby preventing movement of the movable member in the opening direc

Abstract: A self-supporting structural unit having a three-dimensional surface comprising: a first plurality of identical polygons, such as, for example, equilateral triangles, having predefined, fixed areas and equal sides of a predetermined constant length: and a second plurality of polygons, such as, for example, hexagons, having various areas but with equal sides of a predetermined constant length, the sides of the first plurality of polygons being equal in length to the sides of the second plurality of polygons and being secured thereto and in coextensive alignment therewith, the vertices of the first plurality of identical polygons and the second plurality of polygons lying substantially in the three-dimensional surface of the self-supporting structural unit.

Abstract: An improved self-locking device for locking a movable structural member to a stationary structural member, or to another movable structural member, or for unlocking the same, comprising a rotatable self-locking cam and an actuating means therefor; the rotatable self-locking cam being rotatably mounted on a first structural member and having (1) an arcuate surface thereon, capable of preventing movement of a movable structural member in a first or opening direction, and (2) a cam surface thereon, capable of moving the movable structural member in the first or opening direction; and the actuating means being capable of rotating the self-locking cam in an angular direction whereby the cam surface contacts an ear on the movable structural member to forcibly move it in the first or opening direction, while the arcuate surface is being simultaneously moved out of the way of the movable structural member, due to the angular rotation of the self-locking cam, to permit the movement of the movable structural member in

Abstract: A ball pick-up, storage, and individual delivery device comprising: an elongated tubular canister capable of receiving and storing a plurality of balls therein; ball guiding and retaining fins at one end of the elongated tubular canister for guiding the balls into the elongated tubular canister and retaining them therein, after the ball guiding and retaining fins has been placed over and around the balls one at a time and pressed downwardly around the balls to squeeze them and force them to enter the elongated tubular canister; a spring located within the elongated tubular canister urging the balls in the direction of the ball guiding and retaining fins with the outermost ball contacting the ball guiding and retaining fins; and a base located at the other end of the elongated tubular canister having a sufficiently large surface area as a base to permit the elongated tubular canister to be inverted and to stand upright thereon, with the outermost ball contacting the guiding and retaining fins in position to be

Abstract: An improved self-locking device for locking a movable structural member to a stationary structural member, or to another movable structural member, or for unlocking the same, comprising a rotatable self-locking cam and an actuating means therefor; the rotatable self-locking cam being rotatably mounted on a first structural member and having (1) an arcuate surface thereon, capable of preventing movement of a movable structural member in a first or opening direction, and (2) a cam surface thereon, capable of moving the movable structural member in the first or opening direction; and the actuating means being capable of rotating the self-locking cam in an angular direction whereby the cam surface contacts an ear on the movable structural member to forcibly move it in the first or opening direction, while the arcuate surface is being simultaneously moved out of the way of the movable structural member, due to the angular rotation of the self-locking cam, to permit the movement of the movable structural member in

Abstract: A face mask blank, with or without an attached head covering, comprising: lines scored, cut, or impressed into the surface of flat, flexible sheet material, outlining thereon at least two or more concentric geometric figures, such as circles or polygons including squares, pentagons, hexagons, etc., of similar shape and outline but of dissimilar area and size; and a slit cut into the flat, flexible sheet material to the center of the concentric geometric figures, permitting a portion of the geometric figures to be angularly rotated to overlap another portion of the geometric figures, whereby the flat flexible face mask blank is transformed into a three-dimensional configuration having very unusual three-dimensional eye contours, or other three-dimensional human or animal facial or body features, such as a three-dimensional nose, or eyebrows, ears, devils horns, rams or goat horns, rhinocerous horns, elephant tusks, walrus tusks, fangs, etc.

Abstract: A captive ball device or apparatus for practice purposes in sports, particularly the various forms of tennis, comprising: a captive ball; relatively inelastic, high strength, high hardness, medium or average cut-growth rate cords attached to the captive ball; and relatively elastic, lower strength, low hardness, high cut-growth rate cords, the ends of which are attached to the ends of the relatively inelastic, high strength cords, the other ends of the relatively elastic, lower strength cords being adapted to be secured to poles or other vertical supports at a predetermined, yet variable, height above the ground or floor and at a predetermined, yet variable, distance from the captive ball.
