International Classification:

G01R 31/08

US Classification:

370241

Abstract:

A method is provided for verifying repairs in a communication system. In an embodiment, a service network receives a notification from an access network for a completed repair at the access network. The service network comprises a service node and the service network exchanges information with the service node through the access network. The service network retrieves a set of attributes from the notification and determines an identity of the service node using the set of attributes. A repair verification test is executed for the completed repair where the repair verification test is based upon the service node. Further, an outcome is determined for the completed repair based upon the repair verification test.

US Classification:

426518, 62374, 62 62

Abstract:

A system and method for chilling a food product in or proximate to a food processing device adapted to dice, slice, shred, chop, or cut the food product is disclosed. The disclosed system and method involves a two or three stage application of a liquid cryogen or carbon dioxide snow to cool the food product. The cooling stages include a first stage of cryogen application upstream of the entrance of the food processing device, a second stage of cryogen application or delivery into one or more zones within the food processing device, and a third stage of cryogen application to the region proximate to and downstream of the exit to the food processing device.

Filed:

Jun 11, 1987

Appl. No.:

7/061676

Inventors:

Lewis Tyree - Oak Brook IL
Martin M. Reynolds - Aurora IL
Gary D. Lang - Naperville IL

Assignee:

Liquid Carbonic Corporation - Chicago IL

International Classification:

F25D 1306

US Classification:

62 63

Abstract:

A cabinet freezer efficiently utilizes a liquid cryogen refrigerant in conjunction with a spiral conveyor which conveys a product load through a temperature gradient within the freezer. The freezer has a lower inlet and an upper outlet for the conveyor and food load thereon. The escape of cryogen vapors created in the freezer from the liquid cryogen is controlled such that at least about 80% of the vapors exit through the upper outlet which is at the warmest zone established as a part of the temperature gradient in the freezer.

Assignee:

Liquid Carbonic Corporation - Chicago IL

International Classification:

F25D 1306

US Classification:

62 63

Abstract:

A food freezer having a thermally insulated enclosure and an endless conveyor having a loading section, a food freezing section and an unloading section. Blowers circulate gas throughout the interior of the enclosure, and devices for injecting liquid CO. sub. 2 to preferably cause CO. sub. 2 snow particles to impinge upon the food products on the belt are located at selected positions about the belt and may be at various vertical levels, some of which are preferably at least slightly above the belt. By piping the liquid CO. sub. 2 so that it flows only upward and/or horizontally toward the spray nozzles within the thermally insulated enclosure, any solid CO. sub. 2 that may accumulate adjacent the upstream side of the spray nozzle orifices is melted by CO. sub. 2 vapor which gravitates upward in the vertical piping.

Assignee:

Liquid Carbonic Corporation - Chicago IL

International Classification:

F25D 1702

US Classification:

62374

Abstract:

A cryogenic freezer having a thermally insulated tunnel-like enclosure with an entrance and an exit and means for conveying products being frozen therethrough. Products are contacted with liquid cryogen at a region generally near the entrance and a blower located closer to the entrance than to the exit controls flow of cryogen vapor. Upstream and downstream baffles and dampers associated with blower are linked together for complementary movement to selectively regulate the upstream and downstream flow of vapor discharged from the blower. Additional blowers circulate the cold cryogenic vapor transverse to the direction of the conveying means. The temperature of vapor leaving the region of the entrance is monitored the orientation of the baffle and damper arrangement is adjusted in accordance with the temperature monitored. The food products can be contacted by liquid nitrogen in a reservoir facilitates cleaning and retards inefficient vaporization.

Assignee:

Liquid Carbonic Corporation - Chicago IL

International Classification:

F25D 1704

US Classification:

62186

Abstract:

A cryogenic freezer apparatus for food products includes a conveyor within a thermally insulated enclosure. A cryogen injecting unit is located in said enclosure adjacent the opening thereof, and responsive to a cryogen control signal for introducing liquid cryogen in said enclosure. A blower unit in said enclosure directs cryogen vapor away from said enclosure opening toward the interior of said enclosure. The output of said blower unit being controllable by a blower control signal. A sensing unit within said enclosure senses the cooling capacity of the cryogen vapor at the enclosure opening and generates a sensor output signal which is indicative of the amount of cryogen vapor escaping out of said opening. A control unit, coupled to said sensing unit, said injecting unit, and to said blower unit generates a cryogen control signal and a blower control signal in response to the sensor output signal. Cryogen vapor escaping from the enclosure is limited to an amount needed to maintain an air lock, thus preventing air intrusion into the enclosure.
