US Patent:

44561890, Jun 26, 1984

Filed:

May 21, 1982

Appl. No.:

6/380531

Inventors:

Donald J. Wheeler - Belton SC
Christopher Cooper - Brunswick OH
Charles R. Krejsa - Northfield OH

Assignee:

International Patents Limited - Grand Cayman

International Classification:

B65H 1742
B65H 7502

US Classification:

242 55

Abstract:

A strip accumulator characterized by a plurality of circumferentially arranged guide assemblies which positively define a spiral strip path for strip material with adjacent turns thereof being maintained in radially spaced relation, and a common drive for uniformly moving the strip guide assemblies to radially expand and contract the spiral path for the strip material for increasing and decreasing the length of accumulated strip material. In one embodiment, the guide assemblies each include a radially movable guide roll basket which contains and guides multiple turns of the strip material along the spiral path with adjacent turns being maintained in radially spaced relation, and uniform radial movement of the guide roll baskets is obtained by a common drive and drag brake assembly or alternatively by a radially extending drive worm in mesh with a rack in the guide roll basket. In another embodiment, the strip guide assemblies each include a radially extending strip guide and support worm which directly supports the strip thereon with adjacent turns thereof being maintained in radially spaced relation by the turns of the worm. Uniform rotation of the worms by a common drive assembly drives the strip turns radially inwardly and outwardly for filling and emptying of the accumulator.

Abstract:

A strip accumulator and method characterized by a plurality of circumferentially arranged strip guide basket assemblies which positively define a spiral path for the strip material with adjacent turns thereof being maintained in spaced relation, and means for uniformly moving the strip guide basket assemblies radially to expand and contract the helical path for the strip material so that a reserve capacity of strip material may be stored in the accumulator and withdrawn as needed to provide for continuous feed of the strip material to a continuous processing line and the like despite interruptions in the in-feed to the accumulator as when the end of the coil is reached and a new coil is required to be welded thereon. The strip accumulator consists of a plurality of equally circumferentially spaced roll support columns or frames for the strip guide basket assemblies that are mounted for radial movement on rails and provided with one or more guide roll assemblies at various elevations and angles which contain, support and guide the strip material along such spiral path or, more accurately, a helical path. Uniform radial movement of the frames may be obtained by a common drive and drag brake assembly connected to each frame by a bi-directional cable and capstan arrangement, such being operative to drive the frames radially outwardly during filling of the accumulator, and place a drag on the frames as they are drawn radially inwardly during emptying of the accumulator.

Abstract:

A method of igniting liquid fuel in a turbomachine combustor is provided. The method includes a step of initiating a flow of gaseous fuel from a gaseous fuel supply to a gaseous fuel nozzle. The method further includes a step of initiating a flow of liquid fuel from a liquid fuel supply to a primary liquid fuel cartridge. After initiating both the flow of gaseous fuel and the flow of liquid fuel, the method includes a step of igniting the flow of gaseous fuel and the flow of liquid fuel with an igniter. The method further includes a step of terminating the flow of gaseous fuel from the gaseous fuel supply to the gaseous fuel nozzle.
