Appl. No.:

10/062616

Inventors:

Gary Sigel - Lancaster PA, US
Jeffrey Ross - Lancaster PA, US
Elizabeth Malkowski - Lancaster PA, US
Richard Herr - Lancaster PA, US
Larry Leininger - Akron PA, US

Assignee:

Armstrong World Industries, Inc.

International Classification:

C08K003/00

US Classification:

522/083000

Abstract:

The invention comprises a composition and method for controlling the gloss of surface covering products through curing of the composition to create a wearlayer surface, and preferably on a floor covering product. The surface covering product preferably is prepared by application of an aromatic polyester acrylate composition including a flatting agent and/or hard particles, and at least one free-radical generating compound to a substrate, and then the coating is partially cured by exposure to low peak irradiance UV light in either ambient or inert air, followed by fully curing the coating with high peak irradiance UV light in preferably an inert atmosphere to form a low gloss abrasion resistant wearlayer surface. Alternatively, a high gloss wearlayer surface is obtained by solely exposing the preferred composition to high peak irradiance UV light in ambient atmosphere. Furthermore, a differential gloss flooring product is obtained by using the present inventive method described herein.

International Classification:

G11B 21/12

US Classification:

360 75, G9B 21021

Abstract:

In certain embodiments, a method includes calculating a mixing ratio of air internal to a disk drive. In response to the calculated mixing ratio, a head-to-media spacing is adjusted.In certain embodiments, a system includes a controller that adjusts head-to-media spacing in response to a calculated mixing ratio of air internal to a disk drive.

International Classification:

US Classification:

428142

Abstract:

The present invention relates to structures exhibiting unique appearances resulting from the presence of crinkled chip materials. A reflective and/or nacreous platelet or flake material is intermixed with a plasticizer and a general purpose resin, and the mixture is formed into a reflective sheet. The reflective sheet is pulverized to provide a chip material which is then used alone or in combination with other chips to form a mottle comprising a vinyl chloride resin and a plasticizer. Upon consolidating the mottle into a decorative surface, the nacreous and/or reflective chips are found to surprisingly exhibit an enhanced crinkled appearance, thereby exhibiting unique aesthetic properties.

International Classification:

G11B 5/265

G11B 5/455

Abstract:

Narrow band dwell occurs when air bearings corresponding to a set of read and/or write heads within a hard disc drive remain within a fixed narrow band of one or more storage platters for an extended period of time. The air bearings displace lubricant on the storage platters and may redeposit the lubricant as droplets on the platters. The presently disclosure technology is directed to monitoring a hard disc drive for narrow band dwell, and in some implementations, implementing operations to mitigate narrow band dwell. More specifically, the presently disclosure technology may detect an overflying air-bearing slider position, apply a lubrication film displacement formula to a narrow band of the storage platter, apply a lubrication film reflow formula to one or more other narrow bands of the storage platter, and track lubrication film thickness over time in each of the narrow bands of the storage platter.
