Patent number: 9809968Abstract: A corrugated thermoplastic leaching chamber has sidewall louvers that define sidewall slot openings. Each louver comprises an outward extending canopy, a cap integral with the outer end of the canopy, having a down slope greater than the slope of the canopy, and a preferably concave fence at the inner end of the canopy, for inhibiting ingress of soil. The chamber may be made by first thermoforming sheet material, preferably two-layer PET plastic sheet to the shape of the chamber, followed by mechanically cutting and deforming the sidewall, to create the opening and the fence.Type: GrantFiled: August 28, 2015Date of Patent: November 7, 2017Assignee: INFILTRATOR WATER TECHNOLOGIES, LLCInventors: Paul R Holbrook, Roy E Moore, Jr., Bryan A Coppes

Patent number: 9752312Abstract: A substantially cylindrical drainage unit for use when buried in soil as part of a wastewater leach field comprises a first plastic bead aggregate mass, optionally with a central perforated pipe, surrounded by a segmented-quilt exterior surface. Quilts are held in place around part or all of a drainage unit by straps, a circumscribing netting sleeve, or by being themselves in the form of tubular sleeves. Preferred rectangular quilt segments contain a second pebble aggregate that is smaller than the first aggregate. Quilts are fabricated by mating two horizontally-moving layers of geotextile and disposing the second aggregate into channels or cavities that are defined by seams that join the layers to each other.Type: GrantFiled: February 29, 2016Date of Patent: September 5, 2017Assignee: INFILTRATOR WATER TECHNOLOGIES, LLCInventors: Paul R Holbrook, Roy E Moore, Jr.

Publication number: 20170001349Abstract: A method of making a plastic tank suitable for containing water comprises forming a tank base which is partially or fully lined with a plastic layer that is different in character or color from the plastic material of the substrate of the tank base. The tank is alternatively formed by injection molding substrate material around the core of a mold which is partially or fully covered by the liner material, and by injecting liner material into the mold to bond it to the tank base substrate in conjunction with retracting part or all of the core, to provide space in the mold for the liner material.Type: ApplicationFiled: September 3, 2016Publication date: January 5, 2017Inventors: Paul R.

Publication number: 20160207254Abstract: A large tubular plastic tank, for use in holding unpressurized water or wastewater, is formed by fusion welding together half-shell parts to form a tubular body. Then end caps are fusion welded onto the outermost ends of the tubular body. Fusion welding fusion weld elements are secured beforehand to one of the mated joining surfaces of the tank parts at a factory; the tank parts are then economically stored or shipped in nested condition to a fabrication site remote from the manufacturing site. Electric or electromagnetic energy is used to melt in situ the fusion weld elements, thereby to make welds between the parts of the tank.Type: ApplicationFiled: July 24, 2015Publication date: July 21, 2016Inventors: Roy E. Moore, JR., Paul R. Holbrook

Publication number: 20160186423Abstract: A method of making a molded plastic arch shape cross section stormwater chamber having a corrugated wall comprises molding half chambers which are connected by hinges at a joint at the top of the chamber. The chambers may be compactly stored and transported in splayed out configuration. Later, upward force is applied to the hinge joint location of each chamber, so the half chambers are rotated by force of gravity, whereby a faying surface on each half chamber is urged toward the like surface of the other half chamber. The faying surfaces are then fused to each other, preferably as a result of prior heating or by melting of a fusion weld element that is captured in the space between the faying surfaces.Type: ApplicationFiled: January 12, 2016Publication date: June 30, 2016Inventors: Bryan A Coppes, Paul R Holbrook, Roy E Moore, JR., Mark Youngclaus

Publication number: 20160177525Abstract: A substantially cylindrical drainage unit for use when buried in soil as part of a wastewater leach field comprises a first plastic bead aggregate mass, optionally with a central perforated pipe, surrounded by a segmented-quilt exterior surface. Quilts are held in place around part or all of a drainage unit by straps, a circumscribing netting sleeve, or by being themselves in the form of tubular sleeves. Preferred rectangular quilt segments contain a second pebble aggregate that is smaller than the first aggregate. Quilts are fabricated by mating two horizontally-moving layers of geotextile and disposing the second aggregate into channels or cavities that are defined by seams that join the layers to each other.Type: ApplicationFiled: February 29, 2016Publication date: June 23, 2016Inventors: Paul R Holbrook, Roy E Moore, JR.
