Abstract: A process for preparing multi-level, selectively expanded, resinous sheeting comprising:(A) providing a composite comprising a backing material and adhered thereto a layer of a foamable resin which contains a blowing agent;(B) forming a partially printed composite by applying to a portion of the surface of the layer a composition containing an accelerator which functions to lower the temperature at which the blowing agent decomposes and by applying to some, but not all, of the other portions of the surface of the layer a composition containing an inhibitor which functions to decrease the activity of the blowing agent; and(C) forming the multi-level, selectively expanded, resinous sheeting by raising the temperature of the printed composite to a level such that the blowing agent decomposes and the resin fuses, the decomposition of the blowing agent evolving gas which causes expansion of the foamable resin in the portion where the surface is not printed and expansion of the foamable resin in the portion where t

Abstract: A water-based embossing composition for use in chemically embossing a foamable polymeric material having a blowing agent incorporated therein comprising: (A) a film-forming resin dissolved or dispersed in said aqueous composition; (B) a modifier which is effective in modifying the activity of the blowing agent comprising particulate solids which are substantially insoluble and uniformly dispersible in the liquid medium of the embossing composition and which have an average particle size of no greater than about 100 microns, said modifier being present in the composition in an amount of at least about 3 wt. %; and (C) optionally, a colorant or a softening agent for the modifier solids or a mixture thereof.

Abstract: Correctly spelled compound words are provided as candidates to replace a misspelled compound word in many natural languages such as Dutch, Danish, German, Icelandic, Norwegian, Swedish, Swiss German, etc. The basic technique consists of looking up words in a dictionary by the association of component flags with each possible constituent word within the misspelled compound word as well as with the possible replacement candidates for each letter string between these possible constituent words, and by the application of powerful tree-scanning techniques that isolate the possible components of a compound word and determine their correctness in isolation and association of each other.

Abstract: This invention describes a method for automatically verifying spelling of compound words in many natural languages such as German, Danish, Swedish, Norwegian, Dutch, Icelandic, Afrikaans, Swiss German, etc. The basic technology of looking up words in a dictionary is supplemented by the association of component flags with each word and by the application of powerful tree-scanning techniques that isolate the components of compound words and determine their correctness in isolation and in association with each other. The technique can be used in word processing systems to support spelling verification, to hyphenate text, and to unhyphenate text.

Abstract: Methods of obtaining deep through penetration of colorants into firmed printable gelled plastisol or sintered dry-blend polyvinyl chloride compositions which comprise: applying a transfer paper or other substrate coated with a sublimable disperse dye to the surface of a firmed printable gelled plastisol or sintered dry-blend polyvinyl chloride composition, wherein the polyvinyl chloride resin is in particulate form having an average particle size of from about 0.5 micron to about 420 microns and contains specified percentages of plasticizer and stabilizer; applying heat thereto in the range of from about 300.degree. F. to about 430.degree. F.

Abstract: In the art of making chemically embossed sheets of resinous material for use as floor, wall, desk and table coverings, a method of salvaging and recovering a backing sheet material and a potentially foamable, gelled plastisol composition on which has been improperly or inaccurately applied a printing ink composition containing an anhydride having blow-modifying properties which comprises: (1) treating the printing ink composition and the potentially foamable, gelled plastisol composition with a neutralizing, inhibiting or negating composition capable of destroying or rendering substantially ineffectual the blow-modifying properties of the anhdride without destroying or rendering ineffectual the blowing and foaming properties of the potentially foamable, gelled plastisol composition; (2) reprinting the potentially foamable, gelled plastisol composition with another printing ink composition containing a blow-modifier; and (3) blowing or foaming the potentially foamable, gelled plastisol composition, whereby che
