Abstract: A method and apparatus is provided for the continuous microbial remediation of organic wastes in sewers and other waste-laden environments utilizing in-situ microbial seeding. A bio-reactor containing inoculated carrier media is suspended within a sewer wet-well or other similar environment, and is at least partially immersed in the waste-laden fluid to be treated. Air and nutrients are continuously supplied to the bio-reactor via conduit from a remote, easily accessible location. Beneficial microbial populations are permitted to thrive and spread throughout the waste-laden environment, mineralizing organic wastes and eventually becoming dominant within the subject environment.

Abstract: A reusable mat system for the construction of load bearing surfaces, such as temporary roadways and equipment support surfaces, over unstable or unsubstantial terrain, comprising durable, interlocking individual mats which can be quickly and easily installed in a single application, and which can thereafter be easily removed and stored until needed again. The individual mats of the present invention interlock on all sides to form stable and continuous load bearing surfaces, and exhibit favorable traction characteristics.

Abstract: A method and apparatus is provided for removing fluids, particularly entrained and/or adherent fluids, from drill cuttings generated during the well drilling process. A generally cylindrical wire-wrapped screen having a bore therethrough rotates about its longitudinal axis. Suction pressure is applied through the inner bore of the cylindrical wire-wrapped screen. As fluid-laden drill cuttings are deposited on the outer surface of the cylindrical wire-wrapped screen, fluids are drawn off of the cuttings and evacuated from the inner bore of the cylindrical wire-wrapped screen. Solid components of the cuttings remain on the outer surface of the cylindrical wire-wrapped screen and eventually roll off the screen. A scraping member is provided to agitate cuttings deposited on the outer surface of the cylindrical wire-wrapped screen.

Abstract: A mold apparatus and method for manufacturing panels having, as desired, one or more areas of reduced material comprising a facing sheet and integrally attached cell forming walls extending in roughly perpendicular fashion from the facing sheet. Additionally, a method for molding panels, including large scale panels, from thermoplastic resins and other moldable materials requiring significantly less energy than other known molding methods, and providing for panels having one or more areas exhibiting continuous outer surfaces on all dimensions. A lower negative mold member has a plurality of upwardly facing positive standoffs defining interstitial channels into which thermoplastic resin or other moldable material is filled. A generally planar upper mold member is placed on the lower mold, and the combined mold assembly is then subjected to elevated heat and pressure, allowing said thermoplastic resin or other moldable material to melt within the interstitial spaces of the lower mold member.

Abstract: A vehicle leveling apparatus for leveling vehicles, especially large recreational vehicles, trailers and the like. A support base having a channel formed by parallel inclined walls is disposed on an uneven parking surface. A leveling track is pivotally disposed within the channel of the support base. The leveling track can be adjusted to different height levels. The leveling track is set at a desired height and tilted toward the wheels of a vehicle. The vehicle is moved onto the leveling track, thereby raising the vehicle into a level position. An adjustable chock prevents the vehicle from traveling off the leveling track.

Abstract: An apparatus for installing pipe such as large diameter casing in a wellbore. Sensors are positioned at a predetermined location at or near the upper surface of elevators suspended from a rig traveling block. As elevators are lowered over a section of pipe, such sensors provide a signal indicating that the elevators are positioned a desired distance below the top of the pipe. The signal alerts an operator that elevators are positioned properly relative to a pipe body so that slips within the elevators will be properly engaged against the outer surface of the pipe and not a connection upset or large diameter external coupling.

Abstract: A method and apparatus for testing blowout preventer systems that enables testing of various size pipe rams, as well as safe and efficient shut-in of a well, without having to trip the entire apparatus out of a well. The testing apparatus generally includes an upper elongated testing cylinder, an upper test seal assembly, a lower elongated testing cylinder, a lower test seal assembly and a test plug. Additionally, the testing apparatus may include a circulating flow assembly, a side-port assembly, and a check-valve assembly, all of which are axially connected in a series to allow the testing tool to be easily lowered into a riser to a subsea blowout preventer assembly. The subject invention permits testing of blowout preventers that are designed to seal around various size pipe diameters during a single pipe trip. The invention also allows the operator to efficiently and safely shut-in a well if a kick is experienced during testing operations.

Abstract: A downhole tool for cleaning internal surfaces of subsea drilling rig equipment, including drilling risers, blowout preventor assemblies and wellhead assemblies, as well as for retrieving wear bushings, comprising an elongated support body, at least a pair of scraper blades and wash ports. A unique method of cleaning internal surfaces of subsea drilling rig equipment and retrieving a wear bushing in a single operation.

Abstract: An assembly for use in connection with lace-type shoes to secure the tongues of such shoes in a stationary position, and to provide a base or foundation for mounting of ornamental displays on the upper surface of shoe tongues. A rigid upper member having one or more bores is attached to the upper surface of a shoe tongue using tacks which are pushed through the shoe tongue and received within such bores. Shoelaces are wrapped around the rigid upper member and thereafter secured. The rigid upper member provides a base or foundation for attaching easily interchangeable ornamental designs.

Abstract: A reusable mat system for constructing roadways and equipment support surfaces comprising a plurality of uniform individual mats which are constructed of lightweight composite materials and which include strengthening agents. The individual mats partially overlap and interlock to form a continuous and substantially smooth surface, to prevent undesired movement of the mats on location, and to permit quick installation of the mats by simple placement methods.
