Patent number: 7568507Abstract: A diagnostic method for a gas supply system includes: determining a desired ramp rate for filling a vessel from a supply of compressed gas; monitoring the actual pressure of gas entering the vessel; and discontinuing the flow of gas into the vessel when the actual pressure deviates from the intended pressure at the desired ramp rate by an undesired amount. A system for carrying out the method includes a flow controller for controlling operation of the supply system to deliver compressed gas from a source to a vessel through a supply line at a desired ramp rate. The system employs a pressure monitor downstream of a control valve for measuring the pressure of gas directed into the vessel and transmitting pressure-related data to the flow controller, which closes the control valve to discontinue filling of the vessel if the actual pressure exceeds a permissible deviation from the intended pressure.Type: GrantFiled: December 6, 2005Date of Patent: August 4, 2009Assignee: Air Products and Chemicals, Inc.Inventors: David John Farese, Todd Eric Carlson, Joseph Perry Cohen, Amanda Elizabeth Witmer, Keith H.

Patent number: 7191805Abstract: A method for detecting the undesirable entry of oxygen into a transfer system that transfers liquid hydrogen from a liquid hydrogen source into a container. A nozzle for use in the transfer system for dispensing liquid hydrogen comprises a housing and an oxygen sensor positioned inside the nozzle for detecting the concentration of oxygen in the nozzle when the liquid hydrogen is not flowing. The sensor emits a signal indicative of the concentration of oxygen in the transfer system before the liquid hydrogen begins transferring. The signal is received by a controller and prevents transfer of liquid hydrogen until the oxygen is removed from the transfer system.Type: GrantFiled: February 6, 2006Date of Patent: March 20, 2007Assignee: Air Products and Chemicals, Inc.Inventors: Joseph Perry Cohen, Frank Kenneth Schweighardt

Patent number: 7028724Abstract: An apparatus and process for measuring the concentration of hydrogen gas being transferred through a nozzle from a source container to a destination container and for providing an alert and/or taking action where hydrogen gas leaks may create an unsafe condition. The invention can accurately and reproducibly respond to and measure the absolute hydrogen gas concentration within the nozzle housing using hydrogen gas sensors that are selective only to hydrogen, which do not require the presence of oxygen to operate and which do not saturate when hydrogen safety levels are reached. These sensors are positioned inside the nozzle housing to allow for the direct and immediate knowledge of the presence of hydrogen gas that cannot be safely determined by other means. An apparatus and process for detecting leaks of liquid hydrogen through a nozzle during transfer of liquid hydrogen from a source container to a destination container are also discussed.Type: GrantFiled: May 30, 2003Date of Patent: April 18, 2006Assignee: Air Products and Chemicals, Inc.Inventors: Joseph Perry Cohen, Frank Kenneth Schweighardt
