Dispensing Tool For Evacuating And Charging A Fluid System

US Patent:
6776186, Aug 17, 2004
Filed:
Jun 7, 2002
Appl. No.:
10/165499
Inventors:
Mark D. Swinford - Dayton OH
Assignee:
Machine Design Specialists, Inc. - Dayton OH
International Classification:
E03C 100
US Classification:
137614, 137605
Abstract:
A tool assembly for connection to a charging inlet tube of a fluid receiving system, and for evacuating and dispensing a charging fluid to the fluid receiving system. The tool assembly includes a tool housing having an upper and a lower housing half and including a plurality of internal valve components. The internal valve components are assembled in sliding engagement with each other within the tool housing and are held in assembled engagement by assembly of the upper and lower housing halves together whereby the tool assembly may be quickly disassembled and assembled for replacement of components. Fluid flow through the tool assembly is directed by an inner body positioned between the upper and lower housing halves, and vacuum and fluid charging is controlled by a vacuum control poppet and fluid control poppet, respectively, which poppets are longitudinally moveable relative to the inner body and to each other. The fluid is discharged from the tool assembly at a charge gate, and a stem member extends through the charge gate for actuating a valve within the inlet tube. The stem member directly engages the charge gate in order to provide for accurate control of the travel distance of the stem member.

Methods And Apparatus For Regulating Gas Turbine Engine Fluid Flow

US Patent:
6775990, Aug 17, 2004
Filed:
Oct 17, 2002
Appl. No.:
10/272799
Inventors:
Mark Douglas Swinford - Centerville OH 45429
International Classification:
F02C 608
US Classification:
60785, 251 62, 251305
Abstract:
A method enables a gas turbine engine to be operated. The method includes directing fluid flow from a source into an inlet of a valve, channeling the fluid flow entering an inlet portion of the valve towards an outlet portion of the valve such that a direction of the fluid flow is changed within the inlet portion, and controlling the amount of fluid flow entering the outlet portion of the valve by selectively positioning a valve disk coupled within the inlet portion of the valve by a valve disk axle. The method also comprises channeling the fluid flow from the inlet portion of the valve through the outlet portion of the valve and into a fluid supply pipe, wherein the valve outlet portion has a substantially right cylindrical shape such that a direction of fluid entering the body outlet portion remains substantially constant therethrough.

Dispensing Tool Assembly For Evacuating And Charging A Fluid System

US Patent:
5560407, Oct 1, 1996
Filed:
Apr 11, 1995
Appl. No.:
8/420098
Inventors:
Mark D. Swinford - Kettering OH
Assignee:
Production Control Units, Inc. - Dayton OH
International Classification:
B65B 300
US Classification:
141385
Abstract:
A generally cylindrical body supports an outlet tube on which is mounted a resilient annular sealing member adapted to be inserted into the tubular inlet fitting of a liquid coolant system. The body also supports a set of arcuate collar sections which surround the sealing member and are cammed inwardly for gripping external threads on the inlet fitting in response to axial movement of a first air actuated annular piston surrounding the outlet tube. The sealing member is expanded radially outwardly into sealing engagement with the inlet fitting in response to axial movement of a second air actuated annular piston confined between the outlet tube and the first piston. A tubular valve member is supported for axial movement within the body in alignment with the outlet tube and moves in response to a third air actuated annular piston for selectively connecting the passage within the outlet tube to a suction passage for evacuating the coolant system and then to a liquid supply passage for filling the system.

Dispensing Tool Assembly For Evacuating And Charging A Fluid System

US Patent:
6029720, Feb 29, 2000
Filed:
Jun 29, 1998
Appl. No.:
9/106889
Inventors:
Mark D. Swinford - Centerville OH
International Classification:
B65B 300
US Classification:
141385
Abstract:
A generally oval upper body supports a generally cylindrical lower body comprising an outlet tube on which is mounted an inner piston containing an annular resilient sealing member adapted to be connected to the tubular inlet fitting of a liquid coolant system. The lower body supports a set of arcuate collar sections which are cammed inwardly for gripping external threads on the inlet fitting in response to axial movement of an outer air actuated annular piston surrounding the outlet tube. The sealing member is compressed axially into the upper face of the inlet fitting in response to axial movement of the inner air actuated annular piston confined between the outlet tube and the outer piston. A tubular valve member comprising an integral air actuated annular piston is supported for axial movement within the upper body in alignment with the outlet tube for selectively connecting the passage within the outlet tube to a suction passage for evacuating the coolant system and then to a fluid supply passage for filling the system. A streamlined obturator mounted in the upper body is aligned axially with the outlet tube and comprises arcuate passageways for flow of the fluid following connection of the valve member to the outlet tube.

Golf Club And Associated Manufacturing Method

US Patent:
5873793, Feb 23, 1999
Filed:
Dec 23, 1997
Appl. No.:
8/997579
Inventors:
Mark D. Swinford - Centerville OH
International Classification:
A63B 5310, A63B 5312
US Classification:
473317
Abstract:
A golf club shaft having a spar, a tube, and a skin is formed which reduces shaft aerodynamic drag. The skin transforms in cross-sectional shape from a circular one at the grip, to a streamlined shape at the shaft tip. The spar introduces stiffness in the plane generally perpendicular to the direction of swing, thereby offsetting the effect of unequal sectional moments of inertia of the streamlined skin. Manufacturing methods are also disclosed.
