Abstract: An anti-skid stud which comprises a plug or matrix in which are embedded one or more wire-like strands of great wear resistance material such as iron, steel, siliceous material, plastics, etc., which protrude from the matrix. The stud is installed in the surface of tires with the wire-like strands protruding to the road surface. These protrusions penetrate ice and snow surfaces to provide anti-skid traction, however on surfaces such as bare concrete these protrusions flex and do not penetrate the surface to cause excessive erosion of the concrete surface.

Abstract: A flexible elastic ring having a generally rectangular cross section with radially inner and outer surfaces. A plurality of rigid members are molded in the ring at circumferentially spaced-apart positions and each of the rigid members extends diagonally from an edge at the radially inner surface to an edge at the radially outer surface of the elastic ring. The ring is mounted in a wheel well of the tire rim with the tire bead overlapping the edge at the radially outer surface to hold down the ring and the ends of the rigid members in that edge. The other ends of the rigid members are located in the edge at the radially inner surface of the ring adjacent a radially extending side surface of the ring for resisting deflection of the side surface which abuts a radially extending surface of the wheel well. The rigid members prevent the ring from rotating out of the wheel well in this manner when the ring is subject to centrifugal force during rotation of the wheel on which the rim is mounted.

Abstract: In a pneumatic tire wherein the aspect ratio is at most 0.6, the carcass reinforcement, seen in meridian section, follows its natural equilibrium profile between the zone of contact of the side walls with the tread reinforcement and the zone of contact of the side walls with the respective bead rings. The profile is tangent to the bead rings, and the bead rings themselves have a reinforced torsional rigidity.

The pouch is filled through the opening in the tubular member which projects through an aperture in the paper container. The tubular member is held to the surface of the container through a locking member and a sleeve member. A projecting portion of the sleeve member is threaded to receive a cap for sealing the container.

Abstract: A rotary airlock for conveying material has a housing which includes a cylindrical wall and a pair of generally flat end walls which together define a cylindrical chamber. A plurality of vanes are secured to a shaft which extends axially through the housing. A plurality of blades are fixedly secured to each vane and are movable in all directions in the plane of the vane to enable the clearance between the blades and cylindrical wall and the end walls of the housing to be adjusted to maintain a seal between the blades and the housing and to minimize the leakage of air and material from the airlock.

Abstract: A multilayer adhesive strip is adhered to the tread of an automobile or other vehicle tire transversely of the tread and generally axially of the wheel. Each layer has a different color, and wear on one part of the strip faster than another will expose a different color or colors that will indicate the wear pattern. Thin easily worn material may indicate the pattern in a mile or two of driving whereas thicker or tougher strips give results over a longer period of use. For example, differential wear in the center indicates over-inflation, differential wear at both ends indicates under-inflation, and differential wear at one end of the strip indicates wheel misalignment.

Abstract: Belted pneumatic tires, each belt ply of which includes both metallic and non-metallic cords interspersed with one another and of which the non-metallic cords are made of a material having a relatively high modulus generally of the same order of magnitude as that of the metal, are disclosed. In a preferred arrangement, each belt ply has steel wire cords arranged in a 1:1 alternating sequence with glass fiber cords. The sequence can be varied by having successive metal wire cords separated by two or more non-metallic cords, or by having successive pairs or greater numbers of metal cords separated by one, two or more non-metallic cords, and so forth. The use in tires of belts of such cords, eliminates tire wear and failure due to buckling and birdcaging of belts formed solely from non-metallic tire cords.

Abstract: A small holder having a pair of jaws, has the general configuration of prior larger holders to be used for opening jars, but the inside surfaces of the jaws have thick cushions to conform to the wall of artist paint tubes. The cushions have thin supporting members to be attached to jaw members and are easily removable for changing to cushions with different thicknesses for holding tubes of different diameters.

Abstract: A hatch cover having a locking mechanism comprising a single hand wheel with a shaft threaded to the cover for limited up and down movement as the hand wheel is turned. A locking strap is hinged on one side of the hatch cover, releasably locked on the other side and has an opening through which the shaft extends. The locking strap is confined between the hand wheel and a thrust washer attached to the shaft in such a fashion that rotation of the hand wheel in one direction produces contact between the locking strap and thrust washer to force the cover downwardly. Rotation in the other direction lifts the hatch cover to permit unlatching of the locking strap and access to the hopper.

Abstract: A rail clip is made by bending a metal rod with a length less than 18 times its thickness so that it has a substantially straight leg which lies substantially parallel to a railway rail in use of the clip and portions on both sides of this leg which press on the rail and a fixed surface, respectively. An arch connecting one of these portions to the leg rises at an angle of less than 45.degree. to the horizontal, proceeding along the rod away from the leg.
