Patent number: 4258125Abstract: A table has a mechanically driven draw bar squeegee mounted thereon to spread ink and other substances in a uniform manner. There is an interchangeable plurality of such squeegees which may be sequentially placed in said table to enable successive layers of different types of materials to be spread, in sequence, over the surface of a paper. This succession of materials includes an isolation layer between successive colors of ink, whereby a mistake on work in progress does not necessarily lead to a final destruction of all previously done work. A feature of the invention is that the pigmented surface of dried ink is not seen through the tint of other material, such as photoresist, for example. Also, a releasable layer may be provided among the successive layers so that a hand proof copy may be transferred, as a decalcomania.Type: GrantFiled: May 8, 1978Date of Patent: March 24, 1981Inventor: Ronald D. Edhlund

Patent number: 4205865Abstract: Latent, sensitizing inks for application to selected areas of substrates by conventional printing methods. The inks comprise a unique vehicle component which is a non-polymeric, oleophilic, organic Arrhenius acid anion having a cationic counter-ion and, in combination with said vehicle component, a thinner and a particulate filler. The latent inks also include at least one color-generating component. A preferred ink comprises as an additional component a polymeric, hydrocarbon, thermoplastic terpene resin which enhances imaging characteristics and allows the use of reduced filler loadings in the composition.Type: GrantFiled: May 17, 1978Date of Patent: June 3, 1980Assignee: Minnesota Mining and Manufacturing CompanyInventors: Heinz E. Lange, Robert J. Maloney, Dean A. Ostlie

Patent number: 4151748Abstract: A thermally sensitive record medium is disclosed. Data is generated on the record medium in response to an application of heat. The record medium is capable of generating data images in more than one color by exposing the medium to more than one temperature level in areas to be imaged. Overlap or interference between two colors is avoided by utilizing at least one color-forming system which requires a thermal decomposition of one system component before it can be reacted to yield color.The record material is made by coating individual layers, each containing a color-forming system or preferably by coating a single layer including all of the color-forming systems.Type: GrantFiled: December 15, 1977Date of Patent: May 1, 1979Assignee: NCR CorporationInventor: Henry H. Baum

Patent number: 4111462Abstract: Latent, sensitizing inks for application to selected areas of substrates by conventional printing methods. The inks comprise a unique vehicle component which is a nonpolymeric, oleophilic, organic Arrhenius acid anion having a cationic counter-ion and, in combination with said vehicle component, a thinner and an oil-receptive, particulate filler. The latent inks also include at least one color-generating component. The ratio of filler to the vehicle component is about 0.5:1 to about 6:1.Type: GrantFiled: July 15, 1975Date of Patent: September 5, 1978Assignee: Minnesota Mining and Manufacturing CompanyInventors: Heinz E. Lange, Dean A. Ostlie

Patent number: 3962489Abstract: A copy sheet that is capable of being printed by a reaction which requires the presence of three components. One of these components is carried by a printing master and another of these components is supplied to the copy sheet immediately prior to the printing operation. The third component is carried by the copy sheet in the form of a layer provided on one side of a carrier sheet forming part of the copy sheet. The printing master is placed on a rotating drum and the layer on the carrier sheet is moistened to supply the still missing component and is thereafter urged into contact with the printing master by means of a counter-pressure roller. If, in making a series of prints on a number of copy sheets, one copy sheet in the sequence should fail to be conveyed to the printing location, the rotating printing master will contact the counter-pressure roller and apply thereto the component carried thereby.Type: GrantFiled: April 26, 1974Date of Patent: June 8, 1976Inventor: Gerhard Ritzerfeld

Patent number: 3931443Abstract: A process for hectographic duplicating, and hectographic copy paper therefor, are disclosed. The hectographic copy paper is formed by applying a coating of a film-forming vehicle and a colourless dyestuff precursor which is sodium p-carboxy phenyl leucauramine, sodium p-sulphophenyl leucauramine of Michler's hydrol methyl ether. The sheets are used to type or otherwise form an imaged hectographic master sheet, which is then contacted with hectographic copy sheets moistened with a spirit duplicating fluid, with the dyestuff precursors converted into dyestuffs on the hectographic copy sheets.Type: GrantFiled: August 6, 1973Date of Patent: January 6, 1976Assignee: Lamson Industries LimitedInventors: David John Neale, Stanford Frederick Dawney
