Filed: 1936-06-08
Abstract: 471,338. Printing. HAYWARD, R. A. June 8, 1936, No. 16034. Drawings to Specification. [Class 100 (ii)] In a method of making printed and coated paper wrappers for food, confectionery, or the like, one side of a smooth surface paper is coated with a background coating of a watercolour paste having an adhesive vehicle, but having a water content which is insufficient to cause expansion and wrinkling of the paper, the paper is dried, and the coated side is then printed thereon with an oil base ink. The printed paper then is preferably coated with a film of wax on at least the printed side. In the method described, a web of paper supplied from a roll is passed between coating-rollers where a background film of water-colour ink or paste is applied to one side, over a drum drier, and then between three sets of printing-rollers where letter and decorative designs are printed on the background in three colours in an oil base ink. The web is then rewound. It can be subsequently waxed by passing it through a bath of wax. The background coating may consist of an adhesive vehicle mixed with a body pigment, glycerine, a coloured pigment, and water, and the water content should not be more than 35 to 45 per cent.

Filed: 1927-06-16
Abstract: 275,572. Onsrud Machine Works, Inc., (Assignees of Onsrud, R. F.). Aug. 4, 1926, [Convention date]. Regulating.-In a turbine provided with a nozzle 10 for starting and ior idle running, the additional nozzles 11 for full-load running are supplied by a passage 23 and a valve 16 actuated by a governing device 30 which is operated by the working-fluid discharged from the rotor vanes 12. The device 30 comprises a lever pivotally mounted on the casing by a pin 38 and bent at its outer end so that this part 35, which carries, angular vanes 36, lies between the first and second wheels 5, 6. A spring 32, the tension of which is adjustable, holds the lever so as to close a relief portion 26 by means of a ball valve 27. The valve 16 has a passage 28 admitting the fluid to its interior and is held closed by a spring 25. The operation of the device 30 is as follows. At low speeds the fluid from the starting nozzle 10 is deflected from the vanes 12 backward into the vanes 36, thereby moving the lever 30 to open the relief port 26. The valve 16 is thereupon opened by the fluid pressure, and the fluid from the chest 14 is admitted to the nozzles 11. At higher speeds the deflection off the fluid is decreased, and the lever 30 tends to return to normal position to close the valve 16 and decrease the speed.
