Albert Brown - New York NY, US

International Classification:

G06F 9/45
G06F 17/50

US Classification:

716 5, 716 4

Abstract:

A method, management tool, or spreadsheet device that allows a user to analyze, compare, and assess various aspects of an electronic design validation process for an integrated circuit. The exemplary method provides a six-sigma measurement of the effectiveness of an electronic design validation process. Furthermore, various different types of electronic design validation processes can be compared and contrasted for their effectiveness for validating the electronic design throughout the design process.

Appl. No.:

6/586116

Inventors:

Assignee:

Leedall Products Incorporated - New York NY

International Classification:

B32B 518

US Classification:

4283084

Abstract:

Method for producing novel multiple use pressure-sensitive transfer elements in the absence of volatile coating vehicles. The invention comprises preparing a molten coating composition including a compatible binder material mixture of hard wax and meltable synthetic resin, and a fluid ink comprising a solution of dyestuff in an oleaginous vehicle which is substantially incompatible with said wax and substantially compatible with said synthetic resin, coating said mixture onto a thin flexible foundation such as a plastic film and cooling to form a solidified cohesive microporous network of said binder material having uniformly dispersed within the pores thereof said fluid ink. Said ink is pressure-transferable from said network incrementally under the effects of imaging pressure along with that surface portion of the binder material network which is pressure-adhered to the copy sheet under the effects of the imaging pressure.

Assignee:

Chemicraft International, Inc. - New York NY

International Classification:

B41M 526

US Classification:

156234

Abstract:

Transfer sheets and ribbons having a thin foundation carrying two superposed heat-transferable coatings. The base coating is cohesive, nonadhesive, substantially colorless and free of coloring matter and oil, and functions as a heat sink to insulate the top layer against excessive melting. The supercoating is more adhesive than the base coating, contains coloring matter and has excellent bonding properties for the base layer and also for receptive sheets including those having very smooth or glossy surfaces and relatively smooth closely-woven fabrics. Heat-transferred images are strongly adhered to the receptive sheet and produce no visible loss of clarity or sharpness if smudged by contact since the portion of the images exposed to contact is free of coloring matter.

International Classification:

B41M 502
B44C 117

US Classification:

156234

Abstract:

Hectograph master webs and sheets formulated to provide sharper, more-complete transfer under reduced imaging pressures, and sharper, more-numerous duplicate copies in the hectograph duplicating process and resistance to adhesion and coating-transfer under the pressures exerted by a hectograph duplicating machine. The receptive surface formed on the master sheet comprises a hard, pressure-adhesive coating consisting by weight essentially of 45 to 65 percent paraffinic wax, 5 to 20 percent hard wax and 15 to 40 percent polybutene polymer having a Staudinger molecular weight of from 10,400 to 12,300 which bonds to the hectograph transfer layer under relatively low, localized imaging pressure but which is sufficiently hard to resist adhesion, sticking and pick-over to hectograph copy sheets during the hectograph copying processes. The receptive coating also provides a barrier against the migration of the hectograph composition and/or of the spirit duplicating fluid into the master sheet.
