Filed:

Nov 23, 1999

Appl. No.:

09/447764

Inventors:

Ronald Arthur DuBose - Marietta GA

Assignee:

Emprise Technology Associates Corp. - Marietta GA

International Classification:

H01M 804

US Classification:

429 13, 429 22, 429 24, 429 25, 429 26

Abstract:

A stream conditioning system for a fuel cell gas management system or fuel cell engine. The stream conditioning system manages species potential in at least one fuel cell reactant stream. A species transfer device is located in the path of at least one reactant stream of a fuel cells inlet or outlet, which transfer device conditions that stream to improve the efficiency of the fuel cell. The species transfer device incorporates an exchange media and a sorbent. The fuel cell gas management system can include a cathode loop with the stream conditioning system transferring latent and sensible heat from an exhaust stream to the cathode inlet stream of the fuel cell; an anode humidity retention system for maintaining the total enthalpy of the anode stream exiting the fuel cell related to the total enthalpy of the anode inlet stream; and a cooling water management system having segregated deionized water and cooling water loops interconnected by means of a brazed plate heat exchanger.

International Classification:

B01D 5306

US Classification:

96125, 96130, 96150, 96154

Abstract:

A species transfer device in communication with at least two streams, one stream having a higher potential of a species than a lower potential stream. The species transfer device is capable of removing a portion of the species from the high potential stream, and transferring the removed species into the low potential stream. The species transfer device incorporates a housing assembly, exchange matrix and optionally, a sorbent. The housing assembly contains both the exchange matrix and optionally a sorbent inside a housing enclosure and between a sealing enclosure, and provides for the entrance and exhaust of the first and second streams therethrough. The exchange matrix can be, but need not be, in the form of a wheel having an average linear coefficient of thermal expansion at 25 to 800Â C. of less than about 20Ã10 /Â C. The housing assembly with the housing and sealing enclosures enables the species transfer device to run efficiently through a range of pressures.

International Classification:

A61B 1736

US Classification:

12830314

Abstract:

A method and apparatus for removing appendage tissue from avian species such as domestic fowl and principally from commercial chickens and turkeys is disclosed. When the appendage is the beak, the method is known as debeaking and the invention is a method comprised of the step of burning and simultaneously cauterizing a hole through a portion of a bird's beak in order to damage the tissue and precipitate eventual rejection thereof outwardly from the point of damage, and apparatus which includes a face mask for positioning the bird's beak between and in contact with opposing electrodes projecting into the apparatus which effect the burning as aforesaid. A power source for the electrodes provides an open circuit voltage of sufficient magnitude to initiate current flow through the beak when opposing sides of the beak contact the electrodes. With current flow initiated, the power source current increases toward a maximum short circuit value sufficient to cause burning of the portion of the beak between the electrodes, while the voltage drops to a value sufficient to maintain the desired current. The preferred control for the power source determines a time intergral of current flowing through the bird's beak and, upon reaching a predetermined time integral of current value, the control de-energizes the power source.

Appl. No.:

Ronald A. DuBose - Smyrna GA

Assignee:

Keevet Laboratories, Inc. - Anniston AL

International Classification:

A61M 3500

US Classification:

604289

Abstract:

A spray vaccination apparatus using a positive-displacement peristaltic pump to deliver vaccinating liquid to the spray nozzles. The vaccinating liquid is contained in a plastic bag similar to an IV bag, and a flexible plastic tube extends from the bag to the spray nozzles. A peristaltic pump engages this tube for positive-displacement pumping. The pump is actuated for a predetermined increment of time, whenever a tray of baby chicks is inserted into the spray vaccination apparatus, thereby spraying the chicks with vaccinating liquid for a predetermined interval. The spray nozzles preferably are equipped with valves which open only while the pump operates, providing a relatively abrupt onset and termination of spray. All elements of the liquid delivery system remain closed and sealed from the atmosphere, thereby maintaining a sterile condition throughout. These components preferably are disposable, eliminating the need to cleanse the system components periodically.
