US Patent:

20080199628, Aug 21, 2008

Filed:

Feb 15, 2007

Appl. No.:

11/706651

Inventors:

John E. Markowski - Berlin CT, US

International Classification:

B05D 1/32

US Classification:

427448, 118721

Abstract:

A method of masking portions of a part from a high temperature coating, such as a plasma flame spray coating includes mask elements that extend between spaced ends. Hook and loop fasteners are associated with the two spaced ends. The hook and loop fasteners are of a material that can withstand very high temperatures such as are experienced in the high temperature coating. The hook and loop fastener elements may be metallic elements. While a single mask element may be utilized to wrap around the part, in another embodiment, a plurality of mask pieces can be assembled together to surround the part.

International Classification:

C23C 14/54
B05C 11/00

US Classification:

427 10, 118712

Abstract:

A method of measuring a coating deposits a layer of coating on an object. A laser beam is projected on the layer of the coating. A reflection of the project laser beam is received by the laser sensor. From this information, the thickness of the layer of the coating on the object is determined. A value related to the thickness of the layer of the coating may then be compared to a desired value.

Inventors:

John E. Markowski - Berlin CT, US

Assignee:

UNITED TECHNOLOGIES CORPORATION - Hartford CT

International Classification:

G21F 3/00
C23C 4/12

US Classification:

2505171, 118713

Abstract:

An observation window is provided for use with a spray booth during a spray coating process where the observation window is located in a position to permit an operator to observe the spray coating process. The observation window is controlled to provide light transmission in the window suitable for the specific spray process being performed. The control can be automatic or operator controlled. The window is adapted to have a different light transmission during different spray processes such as plasma spray and HVOF spray.

International Classification:

B41J 247

US Classification:

347262

Abstract:

A photoplotting apparatus is provided. The apparatus comprises an internal drum plotter and a media sheet handling apparatus for sequentially delivering a photosensitive media sheet to the photoplotter for exposure from a stack of such sheets. The photoplotter has reduced turbulence within the drum during exposure of the media sheet, and the sheet handling apparatus includes means for separating the sheets in the stack from interleaves disposed between adjacent sheets in the stack.

International Classification:

B41J 1500

US Classification:

400634

Abstract:

An apparatus for printing, cutting or otherwise working sheets of sheet material has a friction sheet advance mechanism and a sheet loading mechanism in advance of the feed mechanism having rows of sprocket pins cooperating with complementary rows of sprocket holes in a sheet to assure accurate insertion of a sheet into the sheet advance mechanism and subsequent accurate movement of the sheet through the advance mechanism and past a work station. A photosensor carried by the work head of the apparatus senses one side edge of the sheet as a reference for laterally positioning the work process relative to the sheet, and a transversely extending index edge of an index hole in the proof sheet is detected and used as a reference for the longitudinal positioning of the work process relative to the sheet. When working on both faces of the sheet, the same reference edges are detected and used as references for the work process on the second face as are detected and used as references for the work process on the first face so as to avoid registration errors between the two work processes.
