  • Patent number: 4690382
    Abstract: A one-piece coving strip (10) of the type utilized along fences, rails, or the like, for preventing vegetation growth at the base thereof, comprises an upper fence-engaging portion (22) and a lower ground-engaging portion (24), joined together by curved connections (26,28). The invention is characterized by including attachment fingers (62) or slits (30,36) for directly attaching the upper portion (22) to a chain-link fence (16). The strip (10) covers an area of ground between the fence and the ground-engaging portion (24), preventing vegetation growth and the passage of objects thereunder, as well as the easier removal of litter from the fencing. Optionally, anchoring spikes (38) may be provided for anchoring the lower portion (24) to the ground.

  • Patent number: 4668292
    Abstract: A vehicle traction material comprises a water scavenging agent such as an oxide, and a parting agent such as a stearate or oleate for keeping the material noncaking and free flowing. A relatively dense abrasive agent in either powdery or granular form imparts weight when carried in the vehicle and friction when spread under the vehicle tires. A nonchloride water-soluble melting agent from the group of compounds including nitrates, phosphates, sulfates and glycols liquefies ice and snow. The material is stored and carried in the vehicle by one or more bags (10) having an outer reinforced material (18) that is temperature, puncture and wear resistant and an inner lining (20) that is corrosion resistant and moisture proof. The bag is reinforced by gussets (16) and has a receivable closure (14) and handles (12), as well as stacking ribs (22) to allow several bags (10) of various sizes to be conveniently refilled, handled and stacked in a vehicle compartment.
