  • Patent number: 7198106
    Abstract: The present invention relates to a process and system for the remediation and enhancement of secondary recovery gas from a natural gas well and geologic formation. The present invention employs the use of protic and aprotic solvents which are injected in sequence into the well and geologic formation. The protic and aprotic solvents are injected into the well bore and progress through the geologic fissures and pores of the geologic formation. After reacting with the downhole and geologic formation deposits, the solvent solute, containing the remaining solvent, dissolved solids and debris, and any remaining components are extracted from the well and formation resulting in improved gas well flow rate through the formation and well bore.

  • Publication number: 20050102760
    Abstract: An escape hammer for breaking reinforced glass or other barrier screen material to enable personnel to escape in an emergency, for example, from a high rise building or from a vehicle or other enclosure and comprising a handle (10) and enlarged head (11) with a pointed striking tip (12). The handle is ridged (as at 13) to provide a grip, has a chisel-end (15) to act as a levering tool, and a formation (17, 18) to assist in the removal of broken glass pieces. The whole tool is of steel or of a material of like mass.

  • Publication number: 20040118331
    Abstract: A speed handle for use in combination with a strap winch on a flat bed trailer. The straps used to secure loads on trailers can be 30 to 40 feet in length. There is no good way to wind these straps onto their winch when they are not in use. Currently the job is done by hand which is very slow and tedious. The speed handle engages the lug of the winch and allows the strap to be wound back onto the winch very quickly. The speed handle allows the winding to occur with only one hand so that another hand is free to guide the strap onto the winch drum.
