Patent number: 6981850Abstract: A cryogenic stream is pumped by a cryopump and then vaporized in a vaporizer to produce the pressurized vapor stream. The cryopump is driven by a transmission that is in turn driven by a hydraulic fluid. The hydraulic fluid flows within a hydraulic fluid circuit having first and second hydraulic fluid flow paths. The first of the flow paths is used to drive the hydraulic transmission. The second of the flow paths is dedicated to raising heat. Hydraulic fluid is circulated within the flow path by hydraulic fluid pumps and the amount of heat generated is controlled by adjustable back pressure valves. The adjustable back pressure valves in both fluid flow paths can be adjusted to control the degree to which heat is added to the vaporizer and therefore the pressurized vapor stream. The hydraulic fluid pumps can be driven by diesel engines. Heat may also be recovered from the diesel engines and gear oil used in pumps and the cryopump to also help vaporize the pressurized liquid stream.Type: GrantFiled: September 23, 2004Date of Patent: January 3, 2006Assignees: Praxair Technology, Inc., Halliburton Energy Services, Inc.Inventors: Brian Norman Maltbie, Norman Henry White

Patent number: 6912858Abstract: A cryogenic liquid stream from a storage tank to be pumped is passed through the heat exchanger located within a phase separator vented to atmosphere and a subsidiary cryogenic stream is divided out of the cryogenic liquid stream and is diverted to the phase separator prior to a pump. Low pressure maintained within the phase separator causes the subsidiary cryogenic stream to boil off and form a liquid fraction that covers the heat exchanger. The liquid fraction, which is at a sufficiently low temperature, subcools the cryogenic stream passing through the heat exchanger. Flow of the subsidiary cryogenic stream is suspended when the height of the liquid fraction reaches a predetermined level and is reestablished when the level falls due to boil off. During periods of suspended flow, flow is temporarily reinitiated to prevent the accumulation of warm liquid and vaporized liquid near or at the inlet to the pump.Type: GrantFiled: September 15, 2003Date of Patent: July 5, 2005Assignee: Praxair Technology, Inc.Inventor: Norman Henry White

Patent number: 6810924Abstract: A method and filling station are disclosed for introducing a compressed gas stream into one or more vessels such that upper and lower temperature material limits are not exceeded and preferably such vessels are not over or under filled by controlling the filling temperature of the compressed gas stream. The compressed stream is produced by compressing a stream composed of a vapor phase located within a cryogenic liquid storage tank. The density of the vapor phase is held constant by adding heat to a liquid phase, preferably by addition of a subsidiary stream composed of the compressed gas stream. The filling temperature of the compressed gas stream is controlled by adding heat to the compressed gas stream by a trim heater or to the vapor stream to be compressed by recirculating part of the compressed gas stream to an inlet of the compressor.Type: GrantFiled: March 17, 2003Date of Patent: November 2, 2004Assignee: Praxair Technology, Inc.Inventor: Norman Henry White

Patent number: 6315265Abstract: The invention involves a variable valve timing actuator that allows the opening and closing of engine valves to be variably and individually controlled without using a camshaft. The invention utilizes energy regeneration so energy delivered to a valve while accelerating it is recovered while it is decelerating. Regeneration is preferably provided by potential energy storage devices such as springs. Energy losses are made up by adding energy to the actuator while the valve is stationary (or nearly so) in an open or closed state. This is done by (1) moving the spring seats in relation to the valve, thereby “charging” the springs in relation to the valve, and/or by (2) moving the valve with respect to the spring seats to “charge” the springs with respect to the valve. This energy addition is extremely efficient because it is performed after the potential energy within the springs has already been expended and the valve is sitting stationary in its open and closed positions.Type: GrantFiled: April 13, 2000Date of Patent: November 13, 2001Assignee: Wisconsin Alumni Research FoundationInventors: Scott Peter Adler, Norman Henry Beachley, Frank John Fronczak, Ahmad Mohammad Sabri

Patent number: 6143143Abstract: The invention relates to apparatus for use in the coating of surfaces of substrates by Physical Vapor Deposition systems (PVD) wherein the deposition in material is applied onto the said surfaces by the sputtering of the same using the PVD system. The invention provides means for preventing sputtering material from applying or landing onto surfaces other than which is desired to be coated in the said coating process. The masking means allow the prevention and/or removal of such material which is known as backscattered material and the invention described claims protection for several embodiments and methods of achieving this thereby improving subsequent adhesion propertied and optical quantities, if applicable, of the coating.Type: GrantFiled: September 29, 1995Date of Patent: November 7, 2000Assignee: Applied Vision LimitedInventors: John Michael Walls, Alaric Graham Spencer, Norman Henry White, Alan Robert Waugh

Patent number: 6090247Abstract: The current invention relates to the provision of apparatus for depositing layers of material onto substrates (2) mounted on a carrier (4) all provided in a vacuum chamber (6) wherein the material is deposited by sputtering of targets of the material from activated magnetrons (7, 7') and the deposited material is reacted by providing a reaction producing means (9) which allows the coating material on the substrates to be conditioned to have the required characteristics. The invention provides that any, or any combination, of the material depositing means and/or reaction producing means are formed from either two magnetrons or a magnetron and counter electrode arrangement which are powered by an alternating voltage power supply which allows a reduction in the occurence of arcing and thereby the dimensions of the apparatus in comparison to conventional apparatus can be substantially reduced.Type: GrantFiled: November 17, 1995Date of Patent: July 18, 2000Assignee: Applied Vision LimitedInventors: Norman Henry White, Allen Robert Waugh, Alarie Graham Spencer, John Michael Walls, Hussein J'Afer
