Abstract: This invention relates to apparatus and a method by which a liquid is applied in desired configurations to a continuous web which travels at a relatively high rate. The liquid may be that which is applied by jets or the like. According to this invention after the liquid is applied to the web excess quantities of fusible powder material are applied to the web during travel thereof. Some of the powder material adheres to the liquid, and powder material which does not adhere to the liquid is removed from the web prior to heating of the web to dry the liquid and to fuse the powder material.The liquid which is applied to the web in desired configurations may be a clear or colorless liquid, such as water or the like. The liquid may be a water-base ink or the like. The powder material applied to the wet configurations provide desired color or aesthetic qualities or protective qualities to the configurations and to the web.

Abstract: A pressure-responsive record transfer sheet for use against a receiving sheet which is chromogenically sensitized with a relatively colorless basic chromogenic dye-precursor. The transfer sheet is coated with a frangible transfer coating of plasticized resin or wax, having dispersed therein a solid acidic reactant, such as an acidic clay, which is insoluble in the liquid solvent but capable of reacting with the basic chromogenic dye-precursor to produce useful color when and where brought into reactive contact therewith, as by marking pressure applied to the transfer sheet. Intimate reactive contact for color production on the receiving sheet is achieved at the time and place of the pressure-induced transfer of the coating from the transfer sheet by dissolution of the dye-precursor on the receiving sheet in the transferred liquid solvent in contact with the transferred acidic reactant.

Abstract: Business forms structure which comprises continuous envelopes with insert material. The envelopes are produced in a series and separated by score lines or the like. Within each envelope is at least one element of insert material. Image transfer material is included in the business forms structure so image transfer can occur from the exterior surface of the envelope to the insert material within the envelope. Each element of insert material is attached to an element of insert material in the adjoining envelopes and is retained in a desired position within its respective envelope until the envelope is separated from the series thereof. Thus, printing, typing, and the like can be performed upon the exterior surface of the envelope and, while the insert material is retained in proper location within the envelope, at least a portion of the printed or typed information is applied to the insert material in the desired location thereupon, prior to separation of the envelope from the series thereof.
