Title: Improvements in steering apparatus for ships
IPC: G05D1/02
Filed: 1920-07-02
Abstract: 145,741. Anschutz & Co. July 25, 1916, [Convention date]. Void [Published under Sect. 91 of the Act]. Systems controlling travel for a fixed distance or number of revolutions.-Relates to automatic steering gear for ships of the kind in which the rudder is actuated by a gyroscopic control, and consists in the provision of means whereby the displacement of the rudder is maintained proportional to the momentary deviation of the ship from its course, so that yawing is prevented. The rudder 1 is operated by a sector 2, and worm 5 by a reversible motor 3, steam engine, or other means. The motor is controlled by circuits containing a battery 6, contact 7 carried by the gyroscope 10, contacts 8, 9 carried by a disk 24 mounted concentrically by a disk 11, and contact breakers 25, 26 which, when opened by wedges 27, 28 on the sector 2, limit the displacement of the rudder. The disk 11 carries teeth on its periphery engaging a worm 12 on the motor shalt 4, of smaller pitch than the worm 5 actuating the rudder. In operation, should the ship swing off its course, the contact 7 slides over on to one of the contacts 8 or 9 whereby the motor 3 operates to displace the rudder to bring back the ship to its course. At the same time the worm 12 turns the disk 11 carrying the contacts 8, 9, until the contact 7 reaching the intermediate gap breaks the motor circuit. The ship swinging back to its course causes the contact 7 to reach the other contact 8 or 9, whereby the motor 3 is operated to return the rudder, until the circuit is again broken owing to the turning of the disk 11 by the worm 12. By a series of such operations, the rudder is returned gradually to its amidship position. The gyroscope 10 may be a meridian gyrocompass, in which case any desired course may be set by rotating the disk 24 on the disk 11. In a modification applicable to fast ships, the shaft 4 carries two worms of different pitch, in addition to the worm 5, one of which actuates a nut carrying a dash-pot cylinder with a variable orifice, and the other a nut carrying a spring, between which and the piston of the dash-pot cylinder is held a projection on a rack operating the disk 11. By adjusting the orifice of the dash-pot cylinder, jawing of the vessel may be prevented. In a further modification adapted for steering unmanned craft from a distant point, a steering motor for setting the disk 24 is actuated by a current conveyed by cable, or by a relay controlled by wireless from the shore. The steering motor is carried by the disk 11 and is actuated through a relay to set the disk 24, or alternatively the main motor 3 is actuated direct from the relay, the contact segments 8, 9 operating to cause the contact 7 to assume continuously a neutral position between them, so that a change from direct to gyroscope control can be effected whatever course the vessel is following.

Title: An improved method of facilitating the dispersion of pigments in aqueous emulsions of organic substances containing protein
IPC: C09C3/00
Filed: 1936-07-01
Abstract: A method of dispersing pigments, e.g. titanium dioxide, zinc oxide, lithopone, in aqueous emulsions of organic substances containing protein. e.g. in cold water casein paints or latex, comprises intimately mixing with the pigments up to 2 per cent by weight of alkali metal hexametaphosphates or alkali metal pyrophosphates or both, calculated on the dry pigment, and then adding the mixture to the emulsion.  The amount may be 0,1 to 1 per cent.  Mixtures of tetrasodium pyrophosphate and sodium hexametaphosphate may be used. The hexametaphosphates may be produced by fusing potassium or sodium, dihydrogen monophosphate and chilling the melt rapidly to form a glass, as described in U.S.A. Specification 502,424.  Sodium hexametaphosphate may be made by fusing sodium metaphosphate and rapidly cooling the melt. The hexametaphosphates &c. may be applied to the pigments during or after disintegration of the latter by jets of compressed air or steam.  Reference is made to German Specification 504,598 which discloses the use of alkali metal pyrophosphates or alkali phosphates for preparing dispersions of pigments in water which may contain protective colloids.ALSO:A method of dispersing pigments, e.g. titanium dioxide, zinc oxide, lithopone, in aqueous emulsions of organic substances containing protein, e.g. in cold water casein paints or latex, comprises intimately mixing the pigments with alkali metal hexametaphosphates or alkali metal pyrophosphates or both and then adding the mixture to the emulsion.
