Patent number: 6479704Abstract: The present invention relates to an improved for the hydrogenation of an immiscible mixture of an organic reactant in water. The immiscible mixture can result from the generation of water by the hydrogenation reaction itself or, by the addition of, water to the reactant prior to contact with the catalyst. The improvement resides in effecting the hydrogenation reaction in a monolith catalytic reactor from 100 to 800 cpi, at a superficial velocity of from 0.1 to 2 m/second in the absence of a cosolvent for the immiscible mixture. In a preferred embodiment, the hydrogenation is carried out using a monolith support which has a polymer network/carbon coating onto which a transition metal is deposited.Type: GrantFiled: April 20, 2001Date of Patent: November 12, 2002Assignee: Air Products and Chemicals, Inc.Inventors: Andrew Francis Nordquist, Frederick Carl Wilhelm, Francis Joseph Waller, Reinaldo Mario Machado

Publication number: 20020163248Abstract: A pneumatic system serves as a backup to the electronic system that normally provides load compensation on a railcar truck during both service and emergency applications of the brakes. The pneumatic system compensates for the load railcar bears during service and emergency brake applications whenever the electronic load compensation system fails due to a loss of power or other electrical failure. Ideal for railcar trucks equipped with brake pipe controlled brake equipment, the pneumatic system provides load compensation through use of a four-port variable load valve in combination with a low complexity MC-30A-1 control valve.Type: ApplicationFiled: May 5, 2001Publication date: November 7, 2002Applicant: WESTINGHOUSE AIR BRAKE TECHNOLOGIES CORPORATIONInventors: James A. Wood, John P. Condrasky

Patent number: 6474078Abstract: An apparatus for transferring fluid from a vessel includes a pump, a first conduit, and a control means in fluid communication with the pump and having open and closed positions. The first end of the conduit is in fluid communication with the vessel and a second end of the conduit is in fluid communication with an inlet of the pump. The control means alternates between the open and the closed positions, whereby a stream of fluid flows into the pump inlet from the conduit when the control means first alternates to the open position, the control means alternates to the closed position and the fluid vaporizes in the pump thereby forming a vaporized portion of the fluid, and a stream of the vaporized portion of the fluid flows out of a pump outlet when the control means alternates again to the open position.Type: GrantFiled: April 4, 2001Date of Patent: November 5, 2002Assignee: Air Products and Chemicals, Inc.Inventors: David Jonathan Chalk, Donald Earl Thompson, John Francis Fischl, David John Farese

Patent number: 6474748Abstract: An electronic vent valve for an electronically controlled pneumatic (ECP”) braking system having a plurality of braking sites at which a braking force can be applied. The ECP braking system includes a master controller processing circuit, individual braking control units located proximate each of the braking sites and a brake pipe supplying compressed air to the braking sites. The electronic vent valve is in fluid communication with the compressed air carried by the brake pipe and has an open position for substantially venting the compressed air from the brake pipe and a closed position for substantially retaining the compressed air within the brake pipe. The electronic vent valve includes a control circuit for causing the valve to open during emergency braking operations, thereby assuring a rapid decrease in the brake pipe pressure.Type: GrantFiled: August 6, 1999Date of Patent: November 5, 2002Assignee: Westinghouse Air Brake CompanyInventor: Brian L. Cunkelman

Patent number: 6477468Abstract: A moderate resolution model and computer coed to predict atmospheric density from data of atmospheric drag on satellites. Changes in atmospheric density are easily seen by plotting data from TLE sets, but the data is noisy and generally has many gaps in it. This new process presents a way in which data from several different satellites can be scaled to the same level and merged to form a much better model without gaps and solutions where noise values are averaged to reduce their effects. This results in a model that describes the relative changes in the atmospheric density over time. The absolute density is not modeled in this step, however, using satellites with well know drag properties, the model can be calibrated to give estimates of absolute atmospheric density if necessary. Along with the absolute values, the drag coefficients of all the satellites involved can be estimated.Type: GrantFiled: August 28, 2000Date of Patent: November 5, 2002Assignee: The United States of America as represented by the Secretary of the Air ForceInventor: Scott R. Dahlke

Patent number: 6474077Abstract: Method for delivering a vapor component product to an end user from a storage system which contains the component in coexisting liquid and vapor phases. The method comprises withdrawing from the storage system a component stream comprising vapor at a first total pressure and a first temperature, passing the component stream through a transfer line to a reservoir having an inlet and an outlet, and condensing vapor in the reservoir to provide a liquid component at a second total pressure and a second temperature at the outlet of the reservoir. The liquid component is withdrawn from the outlet of the reservoir and vaporized to yield the vapor component, which is provided to the end user. The invention includes apparatus to effect the steps of this method.Type: GrantFiled: December 12, 2001Date of Patent: November 5, 2002Assignee: Air Products and Chemicals, Inc.Inventors: Alexandre De Almeida Botelho, Ali Fouad El-Agha

Patent number: 6476317Abstract: The invention provides improved shielding from high energy radiation, especially radiation in the form of electrons with kinetic energy from 0.1 to 10 million electron volts. The improvement is produced by the build-up of an electric field in the insulating material which acts to further attenuate or deflect the penetration of such radiation. The electric field builds up in the insulator and surrounding media because of the stopping of charge stemming from prior impinging radiation.Type: GrantFiled: September 7, 1999Date of Patent: November 5, 2002Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Arthur R. Frederickson, Stanley Woolf, John C. Garth

Patent number: 6473596Abstract: A weaker signal receiving system inclusive of stronger nearby-sourced interference signal cancellation capability. Stronger interference signal cancellation is accomplished by actively canceling or subtracting from the received signal an intermediate signal in which the weaker signal has been attenuated but the stronger signal remains. Attenuation of the weaker signal in this intermediate signal is accomplished in a feedback loop arrangement by an amplitude-responsive signal processing element embodied from for example a ferrite material such as yttrium iron garnet disposed in a physical wave propagating and wave amplitude sensitive film. The cancellation or subtracting is accomplished using received signals and without need for a direct output sample of the stronger signal at its source. Military aircraft use of the disclosed system in the microwave and other spectral regions with transmission mode as opposed to reflection mode signal amplitude discrimination by the ferrite device is included.Type: GrantFiled: December 20, 1999Date of Patent: October 29, 2002Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Keith A.
