Patent number: 5765304Abstract: A process for growing a light weight, transportable sod-mat and for facilitating the implantation of such a mat on a lawn bed comprises germinating lawn-grass seeds (5) in a thin layer of growing medium (4) spread over a mat of non-woven polypropylene (3) laying on an impermeable membrane (2). After germination, the mat and the inseminated growing medium is installed over a layer of porous material such as decomposed granite covering a conditioned subsoil. Drip irrigation lines are run through the upper region of the porous material.Type: GrantFiled: December 15, 1995Date of Patent: June 16, 1998Inventor: Edward H. Clark

Patent number: 5762449Abstract: A river bottom fish control apparatus, which includes a mesh grid netting for providing a substrate for plants and other benthic organism growth and for decreasing turbidity in a body of water. The mesh grid netting includes a flexible plastic having mesh openings and apertures forming flaps located at spaced intervals. The apertures are relatively larger than the mesh openings. The apertures may form crescent-shaped flaps having an apex end and a hinge end and may have a recessed portion removed from the apex end of the flaps or a thin strip removed contiguous to the length of the aperture.Type: GrantFiled: July 22, 1994Date of Patent: June 9, 1998Inventor: Donald L. Hey

Patent number: 5746546Abstract: A product for forming a stable resilient surface layer which comprises a particulate aggregate having particles of a plurality of sizes and including fiber strands and a selected amount of water-absorbent, water-activated adhesive particles having a swell volume when absorbing water in a range of 25% to 45%. When subjected to sufficient water the water-absorbent particles swell and bind the aggregate and fiber strands forming a high shear strength, flexible resilient layer.Type: GrantFiled: January 24, 1996Date of Patent: May 5, 1998Assignee: Stabilizer, Inc.Inventors: Jonathan W. Hubbs, James J. Hubbs, Jr.

Patent number: 5678353Abstract: A grass guard for forming a vegetationless border around a perimeter of an object, such as a lawn sprinkler head, is described. One particular embodiment consists of a two layer construction. The top layer is a plastic sheet simulating grass. The bottom layer is made of a heavy grit bonded into a uniform body with a polymer. The layers form a relatively thin, weather resistant, plastically compliant disk with a center hole for stretch, self-adjusting fit over a pre-installed sprinkler head. The device is also easily cut through with a knife to fit various head locations. The bottom layer has an outside vertical edge with a top rounded corner enclosing the top layer to prevent edge delamination or fraying. An adhesive is provided to bond the grass guard to the neck of the sprinkler head to eliminate gap formation around the head. A hammering board can be used to facilitate the installation.Type: GrantFiled: January 9, 1995Date of Patent: October 21, 1997Inventors: Emily Tsao, Chein-Hwa Tsao, Stephen K. Chan

Patent number: RE35989Abstract: A method of conditioning soil and an organic soil conditioner particularly useful in treating athletic fields derived by drying and grinding plants from the Plantago family. The soil conditioner is applied to the surface of tilled soil and thereafter worked into the soil, deep-watered, allowed to dry and packed. Time-released fertilizer may be included in the soil conditioner if desired.Type: GrantFiled: August 27, 1996Date of Patent: December 15, 1998Inventors: James J. Hubbs, Jr., Jonathan Hubbs
