Title: Improvements in and relating to mechanisms for applying liquids to sheets
IPC: B41L7/08
Filed: 1946-01-28
Abstract: <PICT:0608785/III/1> <PICT:0608785/III/2> <PICT:0608785/III/3> A mechanism for applying liquid to a sheet of paper or the like comprises a capillary pad arranged in contact with a liquid-applying roller adapted to apply the liquid to a sheet passing between it and a further roller, wherein said capillary pad is of flat sheet form and is carried in a rigid tray which is movably supported in a manner whereby the capillary pad is inclined upwardly towards said liquid-applying roller and is movable in its own plane so as to present its uppermost longitudinal edge into abutting relationship to said roller. Referring to the drawings, a sheet of paper is fed between a damping roller 3 and a counter-roller 4.  Gear-wheel 5 on roller 3 meshes with gear-wheel 6 journalled in rocking level 7 pivoting freely about the axis of roller 3 between stops 9 and 10. Spring 8 urges lever 7 towards stop 10 and in this position gear-wheel 6 engages toothed segment 11 on printing drum 1 so advancing the sheet to be gripped between drum 1 and pressure roller 2.  Segment 11 then runs off gear-wheel 6 and the damping roller 3 is rotated only by contact with the sheet.  Roller 3 is supplied with liquid from felt pad 36 supported in case 37, inclined upwardly towards damping roller 3.  Liquid is supplied to the pad by pump 21, 22 operated automatically by drum 1.  For this purpose a stop 12 on drum 1 engages lever 16 mounted on a pivot pin 20 and so engages the piston-rod and lifts piston 21 against the action of spring 31, then the release of lever 16 by stop 12 causes piston 21 to return to its original position, thus pumping liquid via pipe 26. The length of the stroke is regulated by a stop lever 29 mounted on a pivot 30 which can be fixed in one of a series of positions. Pipe 26 is connected to the inner of two concentric pipes 32 and 34, the inner pipe having a small number of coarse apertures 33 along its width and the other a large number of small apertures 35.  Pad case 37 fits into guides 39 and can move freely in the guides by means of rollers 38 and can be removed therefrom through holes 40.  The pad 36 is held in contact with roller 3 by means of spring 41.  A cover-plate 43 extends upwardly from the pad and encloses the pipes 32 and 34 and contains an auxiliary pad 42 serving both to enlarge the fluid absorbing capacity and to prevent sudden variations in the fluid supplied to roller 3 by pad 36.  Surplus liquid fed to the pad flows through a drainage hole 44 in the base of case 37 and through a pipe 45 back to reservoir 23.

Title: Process of strengthening paper
IPC: D21H17/37
Filed: 1965-01-21
Abstract: Paper of high dry strength but low wet strength comprises water-laid cellulose fibres bonded together by a complex of a synthetic dry-strength polymer anionic by virtue of a content of acrylic, methacrylic or itaconic acid residues, a salt of tervalent aluminium and a non-thermo-setting cationic synthetic resin that cannot impart wet-strength.  The anionic polymer is water-soluble or water-dispersible and may be fixed on the fibres by the action of the aluminium salt and the cationic synthetic resin in aqueous suspension, which is thereafter sheeted and dried.  The three agents may be added to the suspension in any sequence, or the cationic synthetic resin and aluminium salt can be added together.  The anionic polymer may be a copolymer of acrylamide, methacrylamide, acrylonitrile, methacrylonitrile, an alkyl acrylate, an alkyl methacrylate or an alkyl vinyl ether with acrylic or methacrylic acid, or a condensate of a lower alkylene oxide with a polymer of acrylic acid, methacrylic acid or itaconic acid or with a copolymer of one of these acids or its salt with an ester of acrylic, methacrylic, itaconic, maleic, fumaric or citraconic acid and an alcohol such as methyl, butyl, octyl, dodecyl or cyclohexyl alcohol or a vinyl or vinyloxyalkyl ester of acetic or propionic acid, ethyl or butyl vinyl ether, acrylamide or methacrylamide.  The aluminium salt may be alum, aluminium chloride or aluminium nitrate.  The cationic synthetic resin may be polyethylenimine polyvinylamine; or condensation products of adipic acid, tetraethylene-pentamine and epichlorohydrin; methylamine, ethylendiamine and epichlorohydrin; methylamine, ammonia and epichlorohydrin; ethylene dichloride and 3, 3\sv-iminobispropylamine; adipic acid and tetraethylenpentamine; diethylenetriamine and ethylene dichloride; ethylene diamine and epichlorohydrin; or ammonia and epichlorohydrin; or a quaternized polyacrylamide or a Hoffman degradation product of a polyacrylamide or an acrylamide-vinylpyridine copolymer.  The anionic polymer may be fixed at a neutral or alkaline pH, e.g. 6-8.  A size may be added with the anionic polymer and fixed by the aluminium salt.  This size may be a rosin size, wax size, stearic anhydride, octadecyl keten dimer or octadecyl isocyanate.  Alternatively, a cationic emulsion of a hydrophobic organic cellulose-reactive size, e.g. that prepared by reacting triethylene-tetramine with stearic acid and solubilizing with acetic acid, or a higher aliphatic amine-epichlorohydrin size, may be added with the cationic synthetic resin.

Title: A Process for Increasing the Strength and Elasticity and for Preventing or Decreasing the Subsequent Weakening of Non-loaded Raw or Boiled Fibres in Silk.
Inventor: KORSELT JOHANNES
IPC: D01C3/00
Filed: 1917-03-05
Abstract: 104,684. Korselt, J. Feb. 5, 1916, [Convention date]. Silk, treating; yarns, treating with liquids.- The strength and elasticity of non-loaded raw or boiled silk is increased and the subsequent weakening of the fibres is decreased by treating the silk with alkaloids or their decomposition products which have a more complex molecule than urea or hexamethylene-tetramine, or with derivatives of such decomposition products. The process is limited to the use of substances which do not modify the feel and appearance of the silk, do not give any undesirable colour reactions with iron compounds, and are more easily oxidizable than fibroin, while their primary, and also secondary and following, products of oxidation are more easily oxidizable still than fibroin. In examples, the use of cinchonine, hydrochloride of caffeine, and carbocinchomeronic acid is described. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the precipitation of these compounds within the fibres in a form soluble with difficulty or insoluble, and the use of complex unstable sulphur compounds. This subject-matter does not appear in the Specification as accepted.
