Patent number: 11966158Abstract: The purification of monoalkyl tin trialkoxides and monoalkyl tin triamides are described using fractional distillation and/or ultrafiltration. The purified compositions are useful as radiation sensitive patterning compositions or precursors thereof. The fractional distillation process has been found to be effective for the removal of metal impurities down to very low levels. The ultrafiltration processes have been found to be effective at removal of fine particulates. Commercially practical processing techniques are described.Type: GrantFiled: January 30, 2019Date of Patent: April 23, 2024Assignee: Inpria CorporationInventors: Benjamin L. Clark, Dominick Smiddy, Thomas J. Lamkin, Mark Geniza, Joseph B. Edson, Craig M. Gates

Patent number: 10392252Abstract: A method and apparatus for generating nano particles, including but not limited to nano particles of Ceo, at high concentration. The invention uses a solid aerosol disperser in communication with a furnace tube having a vaporization chamber and a dilution chamber. A heating element surrounds the furnace tube. Heat from the heating element heats bulk materials contained within a gas flow in the vaporization chamber to a temperature sufficient to convert the bulk materials to a vapor phase. Vaporized bulk materials are then moved to a dilution chamber, where an inert gas is introduced through a dilution gas port. The flow of the inert gas into the dilution chamber through the dilution gas port is sufficient to eject the bulk material from the exit of the dilution chamber, thereby condensing the bulk material into nano sized particles in a gas flow of sufficient volume to prevent agglomeration of the nano sized particles.Type: GrantFiled: November 6, 2017Date of Patent: August 27, 2019Assignee: Battelle Memorial InstituteInventors: Amit Gupta, William C. Forsythe, Mark L. Clark

Patent number: 8182711Abstract: The present invention is directed to pyrotechnic aerosol fire suppression compositions that burn rapidly, but coolly. The rapid burning of the compositions of the present invention produces a voluminous flame-suppressive aerosol that is useful in suppressing and/or extinguishing both small and large fires. The compositions of the invention contain at least one oxidizer and a fuel component comprising at least one organic acid salt, which combination produces a rapid burning composition that burns at low temperatures with little or no flame and have a low heat of combustion.Type: GrantFiled: March 8, 2011Date of Patent: May 22, 2012Assignee: Goodrich CorporationInventors: Philip L. Posson, Mark L. Clark

Publication number: 20070163787Abstract: A portable fire extinguishing device capable of suppressing a fire in a room or other enclosed area comprises a housing containing a pyrotechnic composition and a delay fuze. Upon initiation, the pyrotechnic composition burns and generates combustion byproducts that include an inorganic halogen compound that is dispersed as a aerosol of fine particles, or a gas that rapidly condenses into an aerosol of fine particles, the particle size of which is so small that the free-fall velocity of the particles is less than the average air currents in the room. Accordingly, the fire suppression aerosol remains suspended for several hours to act as a fire suppressant and because of its persistence will seek out and suppress even hidden fires.Type: ApplicationFiled: September 8, 2006Publication date: July 19, 2007Applicant: UNIVERSAL PROPULSION COMPANY, INC.Inventors: Philip L.

Patent number: 4357903Abstract: A device for producing a fluid stream of varying composition comprises a chamber having an inlet at one end and outlet at the other. Between the inlet and outlet there are substantially planar pans or baffles positioned normal to the bulk flow of fluid between the inlet and the outlet. These pans are arranged in pairs. Each pan, except those of the pair most remote from the inlet, is spaced from the walls of the chamber to permit air to flow past it. The pans of each pair are also spaced from each other, in a direction parallel to their planes, leaving an empty space along the mid-plane of the chamber. This produces a circulation and mixing of fluid between the pairs of pans or baffles. A secondary stream of fluid is introduced between two pairs of baffles in the intermediate portion of the chamber, so that the composition of the fluid is different in the portion adjacent to the outlet and the portion adjacent to the inlet.Type: GrantFiled: May 22, 1981Date of Patent: November 9, 1982Assignee: Hazleton Systems, Inc.Inventors: Owen R. Moss, Mark L. Clark, E. John Rossignol

Patent number: 4298496Abstract: An improved compressed air nebulizer has been developed such that a uniform aerosol particle size and concentration may be produced over long time periods. This result is achieved by applying a vacuum pressure to the makeup assembly and by use of a vent tube between the atmosphere and the makeup solution. By applying appropriate vacuum pressures to the makeup solution container and by proper positioning of the vent tube, a constant level of aspirating solution may be maintained within the aspirating assembly with aspirating solution continuously replaced from the makeup solution supply. This device may also be adapted to have a plurality of aerosol generators and only one central makeup assembly.Type: GrantFiled: September 19, 1980Date of Patent: November 3, 1981Assignee: The United States of America as represented by the United States Department of EnergyInventors: Henry S. DeFord, Mark L. Clark
