US Classification:

166245

Abstract:

A method of enhancing the remediation of contaminated soils and ground water, production of oil and gas, and production of any solid, gas, and/or liquid from subsurface geologic and man-made formations including the steps of estimating the geometric boundaries of the region containing the material to be recovered, drilling a recovery well(s) into subsurface in a strategic location to recover the material of interest, establishing multiple sources of acoustical power in an array about and spaced-apart from the surface or at various depths below the surface in a borehole(s) and/or well(s), directing a volume of acoustical excitation from the sources into the region containing the material to be recovered, the excitation in the form of either controllable sinusoidal, square, pulsed, or various combinations of these three waveforms, and controlling the phasing, frequency, power, duration, and direction of these waveforms from the sources to increase and control the intensity of acoustical excitation in the region of the material to be recovered to enhance. the recovery of said material from the recovery well(s). The invention will augment any technology affecting the removal of materials from the subsurface.

Appl. No.:

6/796545

Inventors:

Donald C. Hill - Pasadena CA

Assignee:

R. W. Lyall & Company, Inc. - Santa Fe Springs CA

International Classification:

F16L 4702

US Classification:

285 21

Abstract:

An apparatus and method for forming a fusion welded butt joint between thermoplastic pipe sections. Thermoplastic tubular insert sleeves having end flanges are inserted into the ends of the pipe sections with the flanges located in abutting relation. A coupling collar mounting a heating device is slid along one of the pipe sections into overlying relation with the butt joint formed by the engaged flanges. The heating device is energized to fusion weld the coupling sleeve to the pipe sections and to the flanges. The insert sleeves internally support the butt joint area of the pipe sections against thermal sagging during the fusion welding, and the flanges in their molten state tend to flow and compensate for dimensional discrepancies in the pipe sections.

Assignee:

R. W. Lyall & Co., Inc. - Santa Fe Springs CA

International Classification:

F16L 3318

US Classification:

285242

Abstract:

A threadless coupling for rapid connection to a valve or fitting and to pipes or tubing for fluid distribution systems such as for gas or water. The coupling comprises an outer housing having an internal arrangement of O-rings and unique spacers, lock rings and other members for gripping tubing when inserted and, once inserted, the tubing is firmly gripped to provide a substantial amount of tensile resistant loading thereon.

International Classification:

B29C 6534
H05B 344

US Classification:

156158

Abstract:

A fusion weld method and assembly for forming a fusion welded joint between abutting pipe sections having the same exterior diameter and having a predetermined melting temperature. The assembly includes an extruded welding collar having an interior surface fabricated to closely receive the inserted pipe sections. A welding sleeve comprising a pair of spaced apart sections is received within collar recesses dimensioned to place the sleeve in flush relationship with the collar interior and immediately adjacent the pipe sections. The welding sleeve sections are located on opposite sides of the pipe ends to isolate the pipe ends from their heating effect, and the connecting lead between the sections is recessed for the same reason. The close fit of the collar and sleeve sections with the pipe sections enables development of internal bonding pressures sufficient to constrain the wire turns of the sleeve sections against thermal drift, and to produce a fusion bond of adequate depth and continuity.

International Classification:

F16L 2100

US Classification:

285 31

Abstract:

There is disclosed a pipe repair coupling including a barrel formed centrally with a hollow cylinder for telescopical receipt therein of a hollow piston. The barrel is surrounded by a protective sleeve and is formed at one extremity with a first fitting and at the opposite extremity with a neck portion. The piston is formed in its exterior with a plurality of annular O-ring grooves which receive O-rings for dynamic sealing engagement with the interior wall of the barrel. Telescoped within the hollow piston in the area of the O-rings is a tubular stiffener which supports the walls of such piston against radial inward collapse. Consequently, the piston may be telescoped into the cylinder to facilitate connection of the cylinder fitting to an end of a pipe which is aligned axially with a second end spaced therefrom. Such second end may then be easily connected with a fitting formed on the end of the free end of such piston.

R. W. Lyall & Co., Inc. - Santa Fe Springs CA

International Classification:

F16K 2110

US Classification:

1375147

Abstract:

A very reliable, trouble-free, safety shut-off is provided by a poppit valve arranged so that it can be included in series in a flow line. The head of the poppit is mounted upstream from the seat. It is biased open so that fluid can flow through the line at any rate from zero up to some maximum flow velocity. Flow through the valve is arranged so that it impinges upon the valve head, or something fixed to the valve head, whereby kinetic energy is lost at the head. That kinetic energy is used to move the valve head toward the seat until the spacing between them becomes so small that flow velocity is restricted. At that time, velocity through the valve is increased to the point where a large pressure drop appears across the valve and the static head of the fluid is used to force the valve closed and to maintain it closed. A dash pot develops viscous friction which is used both to damp any tendency of the head to oscillate and to prevent valve operation in response to short term transients or perturbations. Constructing the valve so that it is symmetrical about a center line and constructing it so that approaching flow is directed to the outer peripheral areas of the flow path, and then re-directing flow back into the central area of the flow path through the valve, results in a flow configuration that minimizes criticality in the selection of mass and bias and damping rate values.
