Well Head Seal Assembly

View page
US Patent:
4130304, Dec 19, 1978
Filed:
Aug 12, 1977
Appl. No.:
5/824000
Inventors:
Harry D. Hebard - Tulsa OK
Assignee:
Don R. Hinderliter, Inc. - Tulsa OK
International Classification:
F16L 3900
US Classification:
285143
Abstract:
An improved seal assembly for a well head including a ring-shaped seal body positioned in the tubing head, a tubular coupling formed to the seal body and adapted to connect between adjacent portions of inner tubing, a lower seal ring positioned in the tubing head above the seal body and surrouding the coupling, a pliable rubber gasket positioned in the tubing head above the lower seal ring and surrounding the coupling, and an upper seal ring positioned in the tubing head above the gasket and surrounding the coupling. The seal body has a central circular opening and a radial slot for a cable. The lower seal ring has an inner circular section and an outer circular section split into an arcuate outer front section, and an arcuate outer rear section. The outer section has a semi-circular opening along the inner edge. The inner section is provided with a semi-circular opening on the outer edge which mates with the semi-circular opening on the outer section to form a passageway for the cable.

Method Of Producing Hot Mix Asphalt

US Patent:
5352275, Oct 4, 1994
Filed:
Sep 25, 1992
Appl. No.:
7/951084
Inventors:
Robert Nath - Austin TX
Robert Erickson - Georgetown TX
John Wiley - Leander TX
Harry Hebard - Burnet TX
Michael Miles - Georgetown TX
Assignee:
Cyclean, Inc. - Round Rock TX
International Classification:
B01D 5304
US Classification:
95117
Abstract:
An apparatus and process is provided for the production of hot mix asphalt (HMA) by the treatment of virgin material alone or adding reclaimed or recycled asphalt pavement (RAP) of up to 100% of the HMA comprised of reclaimed asphaltic pavement (RAP). The HMA is first heated in either a parallel or a counter flow rotating drum which is supplied with hot combustion gases generated by a remote low NO. sub. x burner. The temperature of hot gases entering the drum is from about 400. degree. to 2,000. degree. F. , and the temperature of gases exiting from the drum is from about 130. degree. to 220. degree. F. The HMA material optionally can be subjected to microwave radiation to raise the material to a final temperature, or optionally to only reorient the dipolar molecules of the material without any measurable heating of the material. The exhaust gas is treated and made environmentally safe. The hot gases exiting from the drum are passed through a knockout box and then through a baghouse having acrylic bags coated with a protective layer of particulate material.

Stand Jumping And Stabbing Guide Device And Method

View page
US Patent:
4603464, Aug 5, 1986
Filed:
Mar 11, 1985
Appl. No.:
6/710730
Inventors:
Roger Smith - Georgetown TX
Harry D. Hebard - Burnet TX
Assignee:
Hughes Tool Company - Houston TX
International Classification:
B21D 3903
US Classification:
29428
Abstract:
A well tool and method for making up and breaking out connections between sections of drill pipe. The tool will jump the upper pipe section out of the connection when the connection has been completely unthreaded, and will guide the upper pipe section during stabbing. A piston and cylinder assembly is mounted on the carriage for raising and lowering the pipe spinner relative to the carriage. The tool also has an actuator and a pilot valve for automatically opening the clamping cylinders of the spinner whenever the upper pipe section is raised by the pipe elevator.

Drill Pipe Spinner

View page
US Patent:
4774861, Oct 4, 1988
Filed:
Nov 5, 1987
Appl. No.:
7/117272
Inventors:
William R. Hamilton - Houston TX
Harry D. Hebard - Burnet TX
Assignee:
Hughes Tool Company - Houston TX
International Classification:
B25B 1350
US Classification:
81 5733
Abstract:
A drill pipe spinner having a body with an open throat for receiving a drill pipe. A pair of cylindrical driven rollers are mounted on the body for rotation about a vertical axis. A pair of pressure arms are pivotally mounted on the body for rotation about a primary pivot pin. A pair of secondary pressure arms are mounted on the primary pressure arms, for rotation relative to the primary pressure arm about a secondary pivot pin. A pair of cylindrical pressure rollers are mounted on the secondary pressure arms, for holding the drill pipe against the driven roller. A pair of piston and cylinder assemblies exert force on the secondary pressure arms, to cause the secondary pressure arms to rotate. The moment arms between the piston and cylinder assemblies and the primary pivot pins are shorter than the moment arms between the piston and cylinder assemblies and the secondary pivot pins. Springs, mounted between the primary and secondary pressure arms, cause the primary pressure arms to rotate with the secondary pressure arms, about the primary pivot pins, until the pressure rollers have contacted the drill pipe.
