Appl. No.:

10/836601

Inventors:

Chang J. Yee - Stow MA, US
John Berrigan - Nashua NH, US
James A. Dougherty - Lowell MA, US

Assignee:

ECRM, Inc. - Tewksbury MA

International Classification:

B41F 1/30

US Classification:

101408, 1014071, 101477, 414797

Abstract:

The present invention relates generally to systems and methods that remove an interleaf sheet interposed between plate sheets from a material stack used, for example, in a computer-to-plate imaging system and/or environment. Embodiments of the system and method can also remove plate sheets from an interleaf sheet, and transport the plate sheet for subsequent imaging.

International Classification:

B65H 1/00

US Classification:

271145000

Abstract:

A cassette tray for use with an imaging system includes a plurality of sides that have a through slot, and a bottom surface that includes a plurality of slots sized to receive a respective plurality of plate stops capable of maneuvering within the plurality of slots, and a second plurality of slots sized to respectively receive a plurality of lift arms. A platform is provided that includes a same plurality of sides as the cassette tray, and a same first plurality of slots as the bottom surface that are aligned with the first plurality of slots of the bottom surface. The platform is positioned within the cassette tray to contact the plurality of lift arms. A plurality of guide blocks, extending outwardly from each of the plurality of sides of the platform, are sized to fit in the through slots, to facilitate movement of the platform within the cassette.

Wheelabrator Environmental Systems, Inc. - Hampton NH

International Classification:

F22B 1702

US Classification:

122512

Abstract:

A protective wall structure for protecting boiler tubing in facilities using refuse as a fuel source to produce steam for electrical power generation. The protective wall structure includes an array of shielding tiles, heat transfer bonding material, and elongated compressible material. The shielding tiles include a front surface facing the interior combustion zone of the facility, a rear surface facing the boiler tubes, and a plurality of sidewall surfaces. The heat transfer bonding material is positioned between the boiler tubes and the rear surfaces of the shielding tiles to permit heat transfer and create a bond between the boiler tubes and the shielding tiles. The elongated compressible material is positioned between the sidewall perimeter surfaces of adjacent shielding tiles to provide an expansion joint. This permits relative expansion between adjacent shielding tiles without cracking upon an increase in temperature in the interior combustion zone.

US Classification:

126152B

Abstract:

The sidewall end grate block includes a first side which can be placed adjacent to a press plate and a second side which is adjacent to another grate block. The first side includes press plate attachment provisions while the second side includes a tension rod attachment provisions. The press plate attachment provisions on the first side include a plurality of holes which are adapted to receive bolts which can be received by a corresponding holes in the respective adjacent press plate. The tension rod attachment provisions on the second side include a cross-shaped hole and locking protrusions which can accept the head end of a tension rod.

International Classification:

F23K 500

US Classification:

104134

Abstract:

A new carriage system for a ram feeder has been designed and is provided. As in the prior art, the carriage system has a drive cart to which is attached a driving force member at one end thereof and a ram member on the other and opposing end thereof. The drive cart is supported by and travels upon a carriage table. The carriage system of the present invention replaces the prior art wheel and flat rail arrangement under the drive cart. The wheels together with the associated problems have been eliminated. In the present invention, the carriage system has a guide member attached to the carriage table and a travel member attached to the underside of the drive cart. The guide member is longitudinally oriented on the carriage table in the direction of drive cart travel and has at least one upper wear portion. The guide member guides the drive cart and the attached ram member during a reciprocating stoke cycle of the driving force member. The travel member has at least one lower wear portion.

International Classification:

B01J 8/18

US Classification:

422145, 422187

Abstract:

Circulating dry scrubbing (CDS) systems and methods utilizes a particle classification unit operation to separate unreacted sorbent (such as lime, limestone, or sodium-based sorbent) such that a reactive fraction of the cut stream may be selectively recovered to a flue gas scrubbing system. This reduces the amount of fresh sorbent that must be supplied for pollutant removal.
