US Patent:

54525411, Sep 26, 1995

Filed:

Aug 5, 1994

Appl. No.:

8/286389

Inventors:

Anthony DeMaio - West Haven CT

International Classification:

A01G 108

US Classification:

47 33

Abstract:

A new and improved modular plant growth prevention apparatus is used in conjunction with a vertical surface extending vertically from the ground and includes a plurality of plant growth prevention modules which are placed on the ground a predetermined distance from the vertical surface. A plurality of first connector assemblies connect the plant growth prevention modules to each other. A plurality of second connector assemblies connect the plant growth prevention modules to the ground. Each of the plant growth prevention modules includes a vegetation-impervious horizontal portion for placement on the ground. The vegetation-impervious horizontal portion includes an outer edge and an inner end. A length between the outer edge and the inner end is equal to or greater than a distance between an outside surface of a wheel assembly and an outside edge of a blade of a mower. A vertical portion projects upward from the inner end of the vegetation-impervious horizontal portion, and the vertical portion prevents the mower from moving closer to the vertical surface than the predetermined distance between a plant growth prevention module and the vertical surface.

Abstract:

A flexible compound comprising PVC or its co-polymers; greater than 10 to 200 parts by weight of at least one bio-based primary plasticizer comprising epoxidized fatty acid esters, wherein the fatty acids are derived from natural oils and animal fats, based on 100 parts by weight of PVC or its co-polymers; and 0.001 to 10 parts by weight of a mixed metal stabilizer comprising a zinc compound and at least one metal compound where the metal is selected from Li, Na, K, Mg, Ca, Sr, Ba, Cd, Al, La, Ce or rare earth metals, based on 100 parts by weight of PVC or its co-polymers, wherein an atomic ratio of metal/Zn for the mixed metal stabilizer is less than 1.0.
