Abstract: An annular meshwork to cover the tread and part of the sidewalls of a tire includes a plurality of flexible, nonstretchable strands extending around the tire, each strand being connected to adjacent strands at spaced apart points to form an annular meshwork or network to improve traction and steering. The sides of the meshwork are defined by end rings, at least one of which is extensible, e.g., elastic, to allow mounting on the tire. The strands adjacent the end rings are fixedly attached to the end rings. The meshes are formed by the strands with a significantly longer dimension in the circular direction of the annular meshwork than in the transverse direction. The connections can be made using clamping devices of which specific embodiments are disclosed. The clamping devices can be provided with a protective layer on the tread-facing (inner) side. The outer side can be provided with projections in the nature of short spikes to enhance traction.

Abstract: A tripod support having a wall and three legs connected to and diverging therefrom substantially symmetrical to an axis perpendicular to the wall. A distal end of one of the legs is formed for mounting on the bridge of the nose of the user. The other two legs are located for resting upon the user's brow and cheekbone in spanning relation to the eye. A standard size soft-sided squeeze bottle of ophthalmic liquid is mounted with its reduced droplet discharge end mounted through an opening in the support wall so as to align the bottle discharge with the user's eye.

Abstract: The tread reinforcement of a pneumatic tire comprises at least two plies of cords that are crossed with respect to each other and oblique with respect to the longitudinal direction. The carcass reinforcement comprises at least one principal ply extending from one bead to the other and two auxiliary plies having cords oblique with respect to the longitudinal direction and arranged one on one side and the other on the other side of the median plane of the tire. The cords of the principal ply are oblique with respect to the radial direction in the zones in which the auxiliary plies are mounted and radial in other zones.

Abstract: This invention relates to the use of a vibrating element (herein disclosed in the form of a ring) inside storage tanks or bins for aiding flow of powdered bulk material therefrom. The vibrating element is isolated from the walls of the storage tank or bin and vibrations are transmitted directly and principally to the material rather than indirectly through the walls.

Abstract: Apparatus for aerating and assisting the discharge of pulverulent or finely divided dry cargo such as bulk Portland cement comprises a discharge hopper with a sloping bottom having a port in its sloping wall and a cylindrical aerating assembly insertable and removable through the port and consisting of an apertured tube into which air is fed under pressure and which is covered by a fabric sleeve.
