Publication number: 20190271168Abstract: A negative-side waterproof shell (W-shell) is retrofitted onto a below ground preexisting building subject to water intrusion. The W-shell includes a high density polyethylene (HDPE) membrane adhered to the building's sidewalls and floor. The HDPE membrane has a metal core (usually aluminum). The W-shell includes a concrete shell formed on an inboard side of the HDPE membrane. Typically, the W-shell's concrete typically includes rebar and supplemental vertical columns which are thicker than the W-shell. The HDPE membrane has overlapped seams at the vertical to horizontal transition regions. The core may be non-continuous, in strips, or may be ferrous or non-ferrous metals, alloys or aluminum alloys. The W-shell covers the building's interior concrete-formed structures. To seal high tide salt water intrusion, the W-shell extends above the high tide water line. Also, drain piping, leading to a sump, may be laid between the membrane and the floor.Type: ApplicationFiled: March 5, 2018Publication date: September 5, 2019Inventor: Richard N. Clark

Patent number: 6499712Abstract: An electro-mechanical dual linear drive system for adjustably power moving a watercraft seat along a linear travel path. A pair of elongate extruded hollow aluminum rails are mounted in parallelism to a fixed seat support structure. An elongate extruded aluminum hollow slide is non-rotatably and slidably mounted within each rail and driven in a linear travel path for moving the seat load. A lead screw is rotatably mounted within each slide and rail and a traveling nut on each lead screw moves the associated slide. A gear reduction drive mounted on each rail is driving coupled for rotating the associated lead screw. A single electric motor is rotationally drivingly coupled to both gear drive units for synchronously rotating the lead screws in response to motor rotation. Each rail and slide are non-circular and complementary for restraining relative rotation therebetween. A laterally protruding flange along one side edge of the rail bottom wall provides an exteriorly accessible mounting flange on the rail.Type: GrantFiled: February 1, 2000Date of Patent: December 31, 2002Assignee: Tecla Company, Inc.Inventors: Richard N.
