Free-Diaphragm Pump

US Patent:
6402486, Jun 11, 2002
Filed:
Sep 4, 2001
Appl. No.:
09/946752
Inventors:
Ricky B. Steck - West Jordan UT
Michael R. Dunn - Sandy UT
Troy Orr - Draper UT
Matthew J. Stillings - Sandy UT
David Kingsbury - West Jordan UT
Assignee:
Trebor International, Inc. - West Jordan UT
International Classification:
F04B 4306
US Classification:
417395, 417 63, 418 2
Abstract:
A pump for ultra-pure fluids comprises a flexible diaphragm separating a fluid chamber from an air chamber. The diaphragm creates an airtight seal between the fluid chamber and the air chamber when a self-centering and trapezoidal shaped wedge compressively forces the diaphragm into a trapezoidal shaped perimeter cavity surrounding the chambers. Any leak from the fluid chamber into the air chamber is detected by a fiber optic system comprising two optical fibers that are disposed at an angle that is calculated to enable light to pass between the fibers only in the presence of a liquid having a predetermined index of refraction. The fiber optic system can also be used to determine the stroke of the pump by disposing the fiber optic lines at an angle calculated to reflect light off of the oscillating diaphragm when the diaphragm arrives at a predetermined location.

Fiber Optics Systems For High Purity Pump Diagnostics

US Patent:
6695593, Feb 24, 2004
Filed:
Jun 11, 2002
Appl. No.:
10/170082
Inventors:
Ricky B. Steck - West Jordan UT
Michael Dunn - Sandy UT
Troy Orr - Draper UT
Matthew Stillings - Sandy UT
David Kingsbury - Sandy UT
Assignee:
Trebor International, Inc. - West Jordan UT
International Classification:
F04B 4306
US Classification:
417395, 417 63, 418 2
Abstract:
A pump for ultra-pure fluids comprises a flexible diaphragm separating a fluid chamber from an air chamber. The diaphragm creates an airtight seal between the fluid chamber and the air chamber. Any leak from the fluid chamber into the air chamber is detected by a fiber optic system comprising an element and two optical fibers that are disposed such that light is detected by the second optical fiber only when the element is not in contact with liquid. A second fiber optic system can also be used to determine the stroke of an oscillating member by disposing the fiber optic lines at an angle calculated to reflect light off of the oscillating member when the member arrives at a predetermined location. The fiber optics are adapted to be resistant to corrosion, non-igniting, and non-contaminating.

High Purity, Non-Contaminating, Burst Disk

US Patent:
5979477, Nov 9, 1999
Filed:
Feb 4, 1998
Appl. No.:
9/018415
Inventors:
Matthew J. Stillings - Sandy UT
Assignee:
Trebor International, Inc. - West Jordan UT
International Classification:
F16K 1714
US Classification:
137 1
Abstract:
A burst disk assembly relies on a brittle material as the burst disk. Conventional manufacturing tolerances are suitable with the mounting assembly. Flatness and collinearly are achieved by an alignment adapter interfacing between an anvil and the burst disk, on the low-pressure side thereof. A seal, typically thinner than the alignment adapter, is held against the high-pressure side face of the burst disk by a pilot or loader face. All materials are ultra-pure, high-temperature tolerant, and non-reactive. Thin films over metal are not used. Reliable, repeatable, predicable burst pressures have been achieved without resort to highly specialized manufacturing processes. Ceramics and crystalline materials may serve as a burst disk, and quartz has been shown effective. Various grades of fluorocarbon materials have been found to provide suitable coatings, fixtures, and seals. Expanded polytetrafluoroethylene forms a suitable seal.

Fiber Optic System For Detecting Pump Cycles

US Patent:
6957952, Oct 25, 2005
Filed:
Jan 30, 2004
Appl. No.:
10/769361
Inventors:
Ricky B. Steck - West Jordan UT, US
Michael Dunn - Sandy UT, US
Troy Orr - Draper UT, US
Matthew Stillings - Sandy UT, US
David Kingsbury - Sandy UT, US
Assignee:
Trebor International, Inc. - West Jordan UT
International Classification:
F04B043/06, F04B049/00
US Classification:
417395, 417 63, 418 2
Abstract:
A fiber optic system for detecting a stroke of a pump, the fiber optic system including a first fiber optic line configured for directing light onto a portion of the pump that moves during the stroke of the pump. The system further includes a second fiber optic line configured for receiving light that has been transmitted from the first fiber optic line and reflected by the portion of the pump, wherein receipt of the light by the second fiber optic line occurs at a specified point during the stroke of the pump. The moving portion of the pump may be the diaphragm, the reciprocating portion, or any other part of the pump that cycles at regular intervals as the pump operates.

Free-Diaphragm Pump

US Patent:
6106246, Aug 22, 2000
Filed:
Oct 5, 1998
Appl. No.:
9/166490
Inventors:
Ricky B. Steck - West Jordan UT
Michael R. Dunn - Sandy UT
Troy Orr - Draper UT
Matthew J. Stillings - Sandy UT
David Kingsbury - West Jordan UT
Assignee:
Trebor International, Inc. - West Jordan UT
International Classification:
F04B 4306, F04B 4900
US Classification:
417395
Abstract:
A pump for ultra-pure fluids, such as hot, de-ionized water, processing acids, and the like, such as those used in the semiconductor processing industries, is designed to operate at greater than 10 and often 30 or 50 million cycles without failure, and to be failclean. A diaphragm pump maintains a free diaphragm, supported in a contoured chamber for driving and being driven by a piston, able to move radially, rather than absorbing misalignment or distortions. A self-energizing, self-centering, trapezoidal seal captures a constant-thickness diaphragm between a head and body forming the chamber of the pump, separating a body portion and a head portion. An oriented, calendered, multi-layered chlorofluorocarbon diaphragm may be the same material chemically as the body, head, or both. Non-reactive pilots control an operating (motive) fluid, detecting the end-of-stroke whether near the head or near the body. An integrated base controller for the operating fluid supports the apparatus, has a quick exhaust for dumping external-controller air overboard after use, and a bias disk to provide precise, digital, spool positioning within an operational range of pressure differentials.
