US Patent:

8108962, Feb 7, 2012

Filed:

Jul 23, 2008

Appl. No.:

12/220286

Inventors:

Michael Davidson - Houston TX, US
Michael Smith - Friendswood TX, US

International Classification:

A46B 11/02

US Classification:

151671, 151431, 15 221

Abstract:

A toothbrush is provided having an elongated handle and a brush head supported by the handle. The brush head has a base and a plurality of bristles that are arranged in sections. Each section has bristles that extend from the base to form a contact surface elevated from the base. One or more of the sections include bristles that extend to varying lengths from the base to form a contact surface that inclines or declines relative to the base. The sections of bristles further include a first outside section having a contact surface that declines inwardly, an inside section, adjacent the first outside section, having a contact surface that declines outwardly toward the first outside section, and a second outside section positioned adjacent an opposite side of the inside section from the first outside section. The second outside section has a contact surface that declines inwardly toward the inside section.

Appl. No.:

7/006487

Inventors:

Stephen R. Hutchins - Golden CO
Michael S. Davidson - Golden CO
James A. Brierley - Wheat Ridge CO
Corale L. Brierley - Wheat Ridge CO

Assignee:

Advanced Mineral Technologies, Inc. - Golden CO

International Classification:

C22B 1104

US Classification:

75118R

Abstract:

A method is provided for the recovery of precious metals, such as gold and silver, from refractory sulfidic material and refractory carbonaceous sulfidic material. The sulfidic material is pulped and bioleached using either facultative or obligate thermophiles at temperatures in excess of about 45. degree. C. and ranging up to about 90. degree. C. The residue remaining from the bioleach is neutralized and washed and the precious metals therein recovered by dissolution.

International Classification:

A46B 5/02
A46B 5/00
A46B 9/04
A46D 3/00

Abstract:

A toothbrush is provided, including an elongated handle and a brush head supported by the handle. The brush head has a base and a plurality of bristles that extend from the base to form a contact surface elevated from the base. The handle includes a thumb press section that include ridges and flat sections. The toothbrush may include a skeletal structure with an overmoulding encasing the skeletal structure. The overmoulding may form the outer surface of portions of the toothbrush, including the thumb press section.

International Classification:

G01V 1/30

US Classification:

702 14

Abstract:

Tools and methods for monitoring a subterranean formation is provided. Methods for monitoring include: creating a time-lapse azimuth stack between an azimuth stack on a first seismic survey and an azimuth stack on a second seismic survey; identifying a lowest root mean square energy and a highest root mean square energy for each time-lapse azimuth stack; and recording an azimuth with largest overall root mean square energy.

Inventors:

- Houston TX, US
Ulrich ZIMMER - Spring TX, US
Michael DAVIDSON - Houston TX, US

Assignee:

CONOCOPHILLIPS COMPANY - Houston TX

International Classification:

G01V 1/28

US Classification:

702 6

Abstract:

A method of event location to avoid first break picking when signals are small or the ambient noise level is high is described. In this method traveltime associated with the maximum amplitude phases (for any mode of wave) are identified and picked from one or more sensors in an array. Difference between the arrival times are then calculated. A grid search (or optimization) techniques are then employed to search for the event location to match the observed time differences.
