Filed:

Jul 3, 1996

Appl. No.:

8/676861

Inventors:

Melinda Kaye Kovach - Woodbury MN
Leigh Allen Mazion - Roseville MN
Eric Julius Donaldson - Saint Paul MN

Assignee:

Imation Corp. - Oakdale MN

International Classification:

B65H 352

US Classification:

271121

Abstract:

A sheet feed apparatus for an imaging device. The apparatus includes a drive roller, plurality of sheets of photosensitive material, a photographically inert liner having upper and lower surfaces and a container for storing the sheets of photosensitive material. Proper feeding of the sheets of material and a stable location of the liner are ensured by appropriate coefficients of friction between the respective components. The top surface (19b) of the liner (19) to the bottom surface (18B) of the sheets (18) has a first coefficient of friction and the bottom of one sheet (18) to the top of another sheet (18) has a second coefficient of friction, the second coefficient friction being less than the first coefficient of friction, whereby multiple feeds of the sheets are reduced. Preferably, the bottom surface (19c) of the liner (19) to the container (16) has a third coefficient of friction, the third coefficient of friction being greater than the first coefficient of friction, whereby the liner (19) is not fed with the last sheets (18). Also preferably, the roller drive surface (25e) to a top surface (18a) of a sheet (18) has a fourth coefficient of friction, the fourth coefficient of friction being greater than the first coefficient of friction, wherein the last sheet (18) may be fed.

Melinda Kaye Kovach - Woodbury MN
Eric Julius Donaldson - Saint Paul MN
Jon Edward Holmes - West Melbourne FL

Assignee:

Imation Corp. - Oakdale MN

International Classification:

G03G 1500

US Classification:

399393

Abstract:

A container and liner combination includes an interlock feature. Multiple sheets of photosensitive material are placed on the liner. The container has a base in which the liner is positioned. The base has a interlock feature and the liner has a mating interlock feature. The interlock feature prevents movement of the liner in the feed direction as well as in a direction opposite the feed direction.

Abstract:

A fluid delivery system includes a status indicator and control system comprising a processor. The processor is configured to receive a first signal indicative of a first status of operations of a spray application system. The processor is further configured to provide to an operator of a spray gun, via a display system, a visualization representative of the first status of operations, and techniques to control the fluid delivery system, wherein the spray application system is configured to deliver at least one fluid to the spray gun during operations.

Inventors:

- Scottsdale AZ, US
Eric Julius Donaldson - Saint Paul MN, US

International Classification:

B05B 7/02

Abstract:

A fluid delivery system includes a first pressure sensor disposed on or near a spray gun and configured to monitor a first fluid, and a second pressure sensor disposed on or near the spray gun and configured to monitor a second fluid. The fluid delivery system further includes control system comprising a processor configured to receive a first signal from the first pressure sensor and to receive a second signal from the second pressure sensor. The processor is further configured to derive a pressure difference between the first and the second pressure sensor representative of a fluid pressure difference between the first fluid and the second fluid and to control one or more pumps to obtain a desired pressure difference.

International Classification:

B05B 12/14
B05B 12/08

Abstract:

A multi-component fluid delivery system includes a first fluid pump and a second fluid pump. The first and the second fluid pumps are not mechanically coupled to each other. The multi-component fluid delivery system further includes a control system comprising a processor configured to derive a slip ratio for the first fluid pump and the second fluid pump. The processor is additionally configured to apply a master-slave motor control to deliver a specified fluid ratio via the first and the second fluid pumps based on the slip ratio.
