Appl. No.:

11/554326

Inventors:

John Baldwin - Houston TX, US

International Classification:

A01N 25/00
A01N 25/24
A01N 37/44
A01N 37/10
C09D 195/00

US Classification:

Abstract:

A composition for application to exterior surfaces, such as trees, so as to prevent animal damage to the exterior surface, has asphalt and denatonium benzoate mixed together. The denatonium benzoate is 1% to 50% by weight of the total composition. The asphalt is between 50% and 60% of the total composition. Naphtha and dimethyl ether are further components of the total composition. The composition is sprayable onto the exterior surface.

Assignee:

Mustang Services Company - Houston TX

International Classification:

G01B 340
G01B 348

US Classification:

33199R

Abstract:

A gauge for determining the pitch diameter of threads on pipe and tubing, for determining the taper of a thread on the pin or box end of tubular structures used in oil and gas exploration an production, and for determining the existence of an out-of-round condition at the location of the threads on such tubular structures. The gauge includes an elongated scale rail, a pair of blade blocks slidably mounted on the scale rail, and a pair of thread engaging blades pivotally supported on the blade blocks. Locking and adjusting elements are provided in association with the blade blocks for locking the blade blocks in a fixed spatial relationship to each other along the length of the scale rail, with the distance therebetween precisely adjusted to a predetermined value. A series of interchangeable blade stop plates are provided for individual cooperative interaction with the thread engaging blades and with the blade blocks to set the blades at a preselected angle in relation to each other in correlation to a specific thread taper dimension which is to be gauged. A set of interchangeable pitch diameter bars can optionally be provided for fixing the distance separating the thread engaging blades at a selected value corresponding to a predetermined pipe thread pitch diameter.

International Classification:

E02D 27/48

E02D 37/00

Abstract:

A method of lifting a structure includes extending a pipe so as to have one end opening to a lens in the earth, connecting a pump to the pipe, and pumping a grout material through the pipe and into the lens so as to cause a strata of the earth above the lens to heave upwardly and to cause the structure to move upwardly. The grout is solidified in the lens. The pipe is removed after the step of pumping. The grout is a low mobility cement grout. A location of the lens nearest to the structure is determined prior to the step of extending the pipe.
