Patent number: 8004102Abstract: The present invention provides a method and apparatus for generating refrigeration in a process operating at sub-ambient temperatures in which the refrigeration is generated by a turboexpander. The turboexpander is coupled to a generator controlled so that its speed is maintained at a setpoint through electromagnetic braking and its power output is maintained at line matching voltage and frequency. The speed control of the generator therefore, also controls the speed of the turboexpander. The setpoint is calculated to be equal to a product of an operational efficiency parameter, U/Co, and a square root of twice the enthalpy drop in the flow passing through the turboexpander divided by a product of pi and a diameter of an impeller employed within the turboexpander.Type: GrantFiled: April 3, 2009Date of Patent: August 23, 2011Assignee: Praxair Technology, Inc.Inventors: Jeremiah James Rauch, Robert Leroy Baker, Gerald T. O'Connor, Michael John Stanko, Murali Chinta

Patent number: 7431240Abstract: This invention overcome the disadvantage of the prior systems and produces a high velocity specially formed and constituted pressure aerodynamic stream for efficiently and effectively removing ice from an aircraft. The specially formed stream includes a stream within a stream, wherein a deicing fluid such a glycol is entrained within and encased by a surrounding jacket of entraining fluid such air. This deicing is now known as coaxial stream/stream within a stream deicing. The special nozzle allows the stream to maintain fluid separation over its flight path so that aircraft contact is made by to be known as coaxial stream/stream within a stream deicing. The coaxial stream/stream within a stream deicing is further enhanced by pressurizing the stream to deliver the stream as a high pressure high velocity stream to improved the aerodynamic sweeping action of the airstream.Type: GrantFiled: August 17, 2000Date of Patent: October 7, 2008Assignee: Honeywell International Inc.Inventors: John Stanko, Lowell Pearson

Patent number: 6547286Abstract: A joint to connect a tubular ceramic element to a tubesheet. The joint has an internal seal housing to retain the tubular ceramic element and an external seal housing connected to the tubesheet to retain the internal seal housing. A ceramic-to-metal seal is located within the internal seal housing and a metal-to-metal seal is located between the internal seal housing and an external seal housing. The external seal housing is connected to the tubesheet. The internal seal housing is assembled in sections to allow assembly of the ceramic-to-metal seal to be assembled and tested prior to joining the tubular ceramic element to the tubesheet. After perfection of such seal, the internal seal housing and tubular ceramic element is inserted into the external seal housing and sealed within the external seal housing by the metal-to-metal seal.Type: GrantFiled: December 27, 2001Date of Patent: April 15, 2003Assignee: Praxair Technology, Inc.Inventors: James Eric White, Michael John Stanko, William Timothy Gleisle, Victor Emmanuel Bergsten

Patent number: 6360992Abstract: A hybrid deicing system for deicing ice or snow covered surfaces comprises a source of pressurized air and a source of pressurized deicing fluid. A nozzle assembly receives the pressurized air and the pressurized deicing fluid at a forward position, a middle position or a rearward position of the nozzle assembly. The nozzle assembly discharges the pressurized deicing fluid and pressurized air as a first independent stream within a second independent stream.Type: GrantFiled: April 10, 2000Date of Patent: March 26, 2002Assignee: Honeywell International Inc.Inventors: John Stanko, Lowell Pearson

Patent number: 5738492Abstract: An air-conditioning unit including a centrifugal blower for centrifugally blowing air having a generally horizontal axis a rotation and a scroll having an elongated discharge plenum above the blower and an air guide about the blower for directing air exiting the blower to the discharge plenum through a discharge port having first and second ends. The air guide has a radius from the rotational axis of the fan which increases from a cutoff point near the first end of the discharge port to the second end of the discharge port. The scroll also has a curved air foil located above the blower and to a side of the blower toward the second end of the discharge port. The air foil has a leading edge near the blower and a trailing edge in the discharge plenum effective to divert a portion of air exiting the blower toward the second end of the discharge port to equally distribute air across the discharge plenum.Type: GrantFiled: July 9, 1996Date of Patent: April 14, 1998Assignee: White Consolidated Industries, Inc.Inventors: John Stanko, Scott Febo

Patent number: 4736689Abstract: A housing adapted to be mounted beneath the top of a table and a shelf sized to fit substantially within the housing are operatively connected by a pair of telescoping rails which guide movement of the shelf between a retracted position in which the shelf is substantially within the housing and an extended position in which the shelf has a substantial portion thereof outside the housing. The rails pivot about an axis to change the height of the shelf with respect to the top of the table and the entire assembly includes a mechanism for securing the shelf in the extended position. The housing includes a vertically stepped slot in which a pin secured to the rails is movable to hold the shelf at predetermined heights with respect to the top of the table corresponding to the steps of the vertically stepped slot.Type: GrantFiled: December 21, 1984Date of Patent: April 12, 1988Assignee: Tiffany Industries, Inc.Inventor: John Stanko
