Filed:

Oct 9, 2003

Appl. No.:

10/682809

Inventors:

Jeffrey Tawyer - Danvers MA, US
Brian Doherty - Weston MA, US

Assignee:

BROOKS - PRI AUTOMATION, INC.

International Classification:

B65H001/00

US Classification:

414/222020

Abstract:

An improved automated material handling system that allows an overhead hoist supported by a suspended track to access Work-In-Process (WIP) parts from storage locations beside the track. The automated material handling system includes an overhead hoist transport vehicle for transporting an overhead hoist on a suspended track, and one or more storage bins for storing WIP parts located beside the track. Each storage bin is either a movable shelf or a fixed shelf. To access a WIP part from a selected shelf, the overhead hoist transport vehicle moves along the suspended track to a position at the side of the shelf. Next, the movable shelf moves to a position underneath the overhead hoist. Alternatively, overhead hoist moves to a position above the fixed shelf. The overhead hoist is then operated to pick a desired WIP part directly from the shelf, or to place one or more WIP parts directly to the shelf. Once the WIP part is held by the overhead hoist, the overhead hoist transport vehicle moves the WIP part to a workstation or processing machine on the product manufacturing floor.

Appl. No.:

6/659633

Inventors:

Brian J. Doherty - Marblehead MA
Andrew C. Harvey - Waltham MA

Assignee:

Foster-Miller, Inc. - Waltham MA

International Classification:

E21B 33127

US Classification:

166179

Abstract:

A deployment system for use in an oil well system or the like that comprises a body for disposition in an elongated tubular casing that carries deployable apparatus for radial expansion into engagement with surfaces of the casing. A first chamber in the body contains incompressible fluid, and a second chamber in the body contains pressurized compressible fluid. A first passage interconnects the first chamber and the deployable apparatus, a second passage interconnects the first and second chambers, and differential pressure responsive means that controls the second passage has a first condition in which the second passage is closed and a second condition in which the second passage is open, the differential pressure responsive means being adapted to shift from the first condition to the second condition when the pressure in the first chamber exceeds the pressure in the second chamber by a predetermined amount.

International Classification:

US Classification:

Abstract:

A burner system particularly useful for downhole deployment includes a tubular combustion chamber unit housed within a tubular coolant jacket assembly. The combustion chamber unit includes a monolithic tube of refractory material whose inner surface defines the combustion zone. A metal reinforcing sleeve surrounds and extends the length of the refractory tube. The inner surface of the coolant jacket assembly and outer surface of the combustion chamber unit are dimensioned so that those surfaces are close to one another in standby condition so that the combustion chamber unit has limited freedom to expand with that expansion being stabilized by the coolant jacket assembly so that compression forces in the refractory tube do not exceed about one-half the safe compressive stress of the material; and the materials of the combustion chamber unit are selected to establish thermal gradient parameters across the combustion chamber unit to maintain the refractory tube in compression during combustion system start up and cool down sequences.
