Filed:

Jun 14, 2013
Appl. No.:

13/918564
Inventors:

Ronald F. Spohn - Getzville NY, US
Ashwini Sinha - East Amherst NY, US
Carl B. Richenberg - Batavia NY, US
International Classification:

F17C 1/00
US Classification:

220586, 427230, 53403
Abstract:

Novel cylinder passivation procedures to increase the room temperature stability of gaseous tin deuteride (SnD) are described. Incorporation of specific organic-containing materials, which when applied onto surfaces of a vessel and/or conduit extending therefrom, can increase the shelf life stability of thermodynamically unstable gases stored within such pretreated vessels.

US Patent:

58825274, Mar 16, 1999
Filed:

Jan 8, 1997
Appl. No.:

8/780509
Inventors:

Bruce J. Rubin - Rochester NY
Carl B. Richenberg - Batavia NY
David M. Melos - Rochester NY
Assignee:

Eastman Kodak Company - Rochester NY
International Classification:

B01D 3700
US Classification:

210769
Abstract:

A process of dissolving solid waste material in packed beds comprises the addition to the packed bed of a solvent for the solid waste and a material which releases a gas on contact with the solvent which forms channels in the packed bed allowing more rapid access of the solvent to the bed.

Stephen P. Chen - Webster NY
Edgar P. Lougheed - Byron NY
Carl B. Richenberg - Batavia NY
Assignee:

Eastman Kodak Company - Rochester NY
International Classification:

G03C 732
US Classification:

210637
Abstract:

A method of preparing a coupler dispersion in gelatin by separating the auxiliary coupler solvent using a hydrophobic microporous membrane and contacting the opposite surface of the membrane with a coupler solvent.

US Patent:

49469657, Aug 7, 1990
Filed:

Jan 23, 1990
Appl. No.:

7/469703
Inventors:

Frank M. Jahnke - Rochester NY
Carl B. Richenberg - Batavia NY
Assignee:

Eastman Kodak Company - Rochester NY
International Classification:

C07D23122
C07C23500
C07C23538
US Classification:

548365
Abstract:

Solid photographic addenda, such as photographic color couplers or sensitizing dyes, which are wet with occluded organic liquid, after being subjected, for example, to processes such as crystallization or washing, are contacted with an extractant composed of carbon dioxide in liquid form or in the form of a supercritical fluid to remove the organic liquid. The process is capable of use with any solid photographic addendum which is insoluble in the extractant and any organic liquid which is soluble in the extractant. It can be completed much more quickly than conventional processes in which such solids are dried with the aid of heat and/or vacuum, while effectively avoiding problems of clumping and thermal degradation which commonly occur in dryers. It provides a product that is capable of meeting the demanding requirements of the photographic art with respect to both physical and chemical characteristics.

US Patent:

20190354122, Nov 21, 2019
Filed:

Jul 31, 2019
Appl. No.:

16/527418
Inventors:

Xuemei Song - East Amherst NY, US
Carl Richenberg - Batavia NY, US
Lloyd A. Brown - Amherst NY, US
International Classification:

G05D 11/13
B01F 15/04
Abstract:

A dynamic blending system and process to produce a mixture of a desired target concentration with minimal tolerance variation and no waste gas generation is provided. The mixture made from the blending process can be utilized without the need to vent. The inventive system and process enables the ability to perform relatively small adjustments to the concentration of the blended gas mixture. The system and process also includes specifically designed sampling protocols that reduce measurement error.
