Patent number: 10439255Abstract: Light is transmitted through or from a separator of a battery cell or scattered within a battery cell and received by one or more light detectors. The light that is normally transmitted through the separator is scattered, absorbed, wavelength-shifted or otherwise distorted by an impending fault in the vicinity of or within the separator. The change in light due to the impending fault is measured by a detector and a signal from the detector is processed to identify the impending fault so that a warning can be generated indicative of the impending fault.Type: GrantFiled: August 9, 2013Date of Patent: October 8, 2019Assignee: Battelle Memorial InstituteInventors: James E. Dvorsky, Steven M. Risser, James H. Saunders, Alexander C. Morrow, David W. Nippa

Patent number: 10302312Abstract: A water heater that includes a cylindrical storage tank, at least one heating element, and at least one temperature sensor is modeled using a one-dimensional model that includes: a vertical stack of disks representing the water volume in the cylindrical storage tank, and a stack of annular segments surrounding the vertical stack of disks. The stack of annular segments represents the cylindrical wall of the cylindrical storage tank. The one-dimensional model may be used by a condition-based maintenance system comprising an electronic data processing device configured to detect a failure mode present in the water heater based on an output of the water heating model component. Some illustrative failure modes include insulation disturbance, heating element failure, excessive sediment buildup, or a drip tube rupture.Type: GrantFiled: December 21, 2015Date of Patent: May 28, 2019Assignee: Battelle Memorial InstituteInventors: Douglas Thornton, Bradley C. Glenn, James H. Saunders, Jason W. Black, Eric Rehberg

Patent number: 6582498Abstract: In a method of separating carbon dioxide from a gas mixture, a liquid solvent flows down an array of vertical wires with the gas mixture flowing over the liquid. Once on the wire, the liquid quickly breaks up into drops of varying sizes, with each size moving down the wire at a different velocity. Large, faster moving drops overtake the small, slower moving drops to form even larger drops. As the drops fall, new drops are created behind the falling drops. Consequently, drops of a large range of sizes are forming, colliding, and mixing as they travel down the wire. During this process, gas molecules that have adsorbed onto the liquid surface are mixed into the interior of the solvent, resulting in highly effective mass transfer and gas absorption. This enhanced mass transfer allows greater flexibility in the choice of solvent and in the system design.Type: GrantFiled: May 4, 2001Date of Patent: June 24, 2003Assignee: Battelle Memorial InstituteInventors: Bruce M.

Patent number: 6454193Abstract: A electrohydrodynamic aerosol sprayer wherein a gas flow deflector is used for creating a gas flow past the spray nozzle to stabilize the Taylor cone and to transport at least a portion of the aerosol away from the region downstream of the spray nozzle. This stabilization of the cone and transport of aerosol improves the droplet size and distribution and may also reduce the deposit of droplets on the internal components of the device.Type: GrantFiled: April 20, 2000Date of Patent: September 24, 2002Assignee: BattellePharma, Inc.Inventors: David R.

Patent number: 6112741Abstract: A multi-category gaseous fuel-fired heating apparatus having a combustion chamber, a mixing chamber in fluid communication with the combustion chamber, and an induced draft blower in fluid communication with the mixing chamber whereby combustion air is drawn into the combustion chamber for combustion of the gaseous fuel and the flue gases are drawn from the combustion chamber through the mixing chamber and exhausted into either a high temperature flue gas vent or a low temperature flue gas vent. The mixing chamber includes a dilution air inlet which, in a high temperature vent mode of operation of the heating apparatus is sealed off by an orifice plate disposed between the mixing chamber and the induced draft blower, and in a low temperature vent mode, the dilution air inlet is open and a larger blower inlet orifice is used.Type: GrantFiled: April 30, 1999Date of Patent: September 5, 2000Assignee: Gas Research InstituteInventors: George H.

Patent number: 5941230Abstract: A gas appliance, flue assembly, or vent adapter including an adjustable flow regulator which regulates the proportions and volume of dilution air and combustion products into the vent is disclosed. The flow regulator can be adjusted to allow a given appliance to exhaust vent gases through a range of different venting systems constructed from a wide range of materials. The appliance installer may adjust the appliance vent gases for a particular pre-existing or installed vent. The flow regulator also provides flow resistance which helps prevent backdrafting and the free escape of dilution air (which may be heated room air in some instances) through the vent to the outside atmosphere.Type: GrantFiled: April 28, 1997Date of Patent: August 24, 1999Assignee: Gas Research InstituteInventors: Allen L.
