IPC: C08F20/62
Filed: 1961-08-14
Abstract: A water-soluble resinous composition capable of air-drying into water-insoluble form comprises a water-soluble salt of the reaction product of a drying oil, maleic anhydride, acrylic and/or methacrylic acid and at least one ethylenically unsaturated monomer which is free from carboxylic acid and anhydride groups. The salts may be formed from an alkali metal or ammonium hydroxide or an amine e.g. diethylamine, dimethylamine, triethanolamine, ethylene diamine, triethylamine, morpholine, 2-amino-gamma-methyl-1-propanol and di-isopropylamine.  Drying oils specified are linseed, soya, dehydrated castor, safflower and tall oils.  Specified monomers are vinyl toluene, styrene, alpha C1-4 alkyl styrenes, alkyl acrylates and methacrylates and mixtures thereof.  The preferred procedure is to react the oil and maleic anhydride and then to add the acid and monomer, preferably incrementally.  The formation of the reaction product may be catalysed by benzoyl or di-t-butyl peroxide or cumene hydroperoxide.  Neutralisation is usually effected by adding the base in aqueous solution which may also include glycol monoethyl ether or ethyl, butyl or amyl alcohol.  The resulting aqueous composition may include an air-drying catalyst e.g. cobalt or lead naphthenate, which is usually added with a wetting agent, and may be used to coat wood, paper, metals and alloys e.g. steel, aluminium and tinplate, fabrics, and films of synthetic thermo-plastic or setting material e.g. polyethylene glycol terephthalate.ALSO:A water-soluble resinous composition capable of air-drying into water-insoluble form comprises a water-soluble salt of the reaction product of a drying oil, maleic anhydride, acrylic and/or methacrylic acid and at least one ethylenically unsaturated monomer which is free from carboxylic acid and anhydride groups.

Title: Anti-heeling device for ships, airships and the like
IPC: B63B39/06
Filed: 1939-11-03
Abstract: 536,031. Gyroscopic apparatus. MINORSKY, N. Nov. 3, 1939, No. 29332. [Class 97 (iii)] [Also in Groups XXXVIII and XXXV] The control of anti-rolling apparatus, for ships &c. in accordance with the response of known apparatus 89 sensitive to the angular acceleration of rolling is supplemented by a control in accordance with the angular acceleration of the ship's yawing motion (weather yaw) and in accordance with the speed of the ship. The apparatus may also control the rudder and reduce the weather yaw. Two oppositely rotating gyroscopes 1, 2 are pendulously mounted on precession axes in a frame carried in gimbals on the ship and restrained by springs 11-14. Studs 20,21 on each are coupled to a rod 26, Fig. 3, carrying coils 27, 28 so that these are moved in the fields of alternating current magnets 30, 31 to produce electro motive forces varying in proportion to the angular velocity of yaw. These are applied respectively to the grid circuits of amplifiers 32 so that opposed direct currents are produced in field coils 100, 101 of a generator 105 and in the primary windings of a transformer 42. The secondary windings therefore produce opposed currents proportional to the angular acceleration of yaw and after amplification energize opposed windings in an electrodynamometer 67 to re-act therein with a coil 65 energized in proportion to the ships speed by a generator 60. A control force proportional to the product of the angular acceleration of yaw and the ship's speed is transmitted from the electrodynamometer by any angle transmitting device, such as the Selsyn transmitter shown to one element 79 of a differential gear whereby movements proportional to the angular acceleration of rolling transmitted to another element 81 from an accelerometer 89 are algebraically added thereto to control a pump P controlling the rate of transfer of fluid between anti-rolling tanks T. The generator 105 actuates a motor 107 in accordance with the angular velocity of yaw to add to the rudder control, through a differential gear 108, a component to correct for the forced yaw. To adjust the zero of the antirolling control to compensate any asymmetry in the behaviour of the ship, manual adjustments 132, 133 may be applied to the stators of the Selsyn receivers 76, 83. To adjust the proportionality factor in the control a rheostat 68 may be provided. To enable a satisfactory control to be obtained when the roll period is long, a switch 40 may be thrown to give a control proportionate to the angular velocity of roll. Specification 408,796, [Group XXXIII], is referred to.

Patent GB-382429-A (GB)
Title: Improvements relating to weighing machines
IPC: G01G21/00
Filed: 1931-10-29
Abstract: 382,429. Automatic-feed weighers. SIMON, Ltd., H. and BRIAN, J. C., Bird Hall Lane, Cheadle Heath, near Manchester. Oct. 29, 1931, No. 29986. [Class 143.] Relates to an automatic weighing machine, such as a grain weigher, of the kind wherein a counterbalancing device assists the movement of the steelyard or equivalent part of the weighing mechanism prior to the dribble feed, and a compensating device is employed to compensate for the falling material at final cut-off. The invention consists in the provision of means which bring the counterbalancing and compensating devices into operation successively and which withdraw the counterbalancing device from the steelvard to enable the latter to return to its initial position before the compensating device comes into operation. In effecting a weighing operation the mechanism is first set in the position shown in Figs. 2 and 4 by raising a handle 17, Fig. 4, the movement admitting compressed air from a valve fitting 32 to open the main valve c, Fig. 1, of the feed hopper a. When the major portion of the charge has entered the weigh hopper b the steelyard e, assisted by the counterbalancing lever f, Fig. 2, rises, displaces a trip lever j, and allows an arm o to fall into the position shown in Fig. '3, a roller q displacing the counter-' balancing lever f clear of the steelyard e, and a lever s freeing the compensating lever g so that it may exert an upward pressure on the steelyard to compensate for the falling grain at final cut-off. In addition, the falling arm o acting through the spindle p causes the parts shown in Fig. 4 to be turned to the position shown in Fig. 5, thus operating the valve in the fitting 32 to admit compressed air to the cylinder 33, Fig. 1, and close the main valve c. During the closing movement, a member on the main valve, operating through a link and catch mechanism opens the dribble feed valve d, which is then held open by a catch. When the requisite quantity of grain has entered the weigh pan, the steelyard e moves upwards and disengages a catch lever z, Fig. 3, from a weighted lever 2 which then falls upon a member 5a and causes an arm 8 to fall and operate a valve 11. Compressed air passes to a cylinder 41, Fig. 1, and liberates the dribble feed valve d to cut off the feed. A part 9 on the falling lever 8 displaces the compensating lever g to leave the steelyard free and allow the operator to check the accuracy of the weighing. The fall of the arm 8 at the completion of the weighing also displaces a lever 45, Figs. 4 and 5, and permits the operator to raise a handle 44 in order to discharge the contents of the weigh hopper by opening an air valve on the spindle 37.

[Also in Divisions F4 and G1] In a steam-heated surface apparatus (see Division F4) a header 2 extends at right angles to the axis of a cylindrical steam vessel 1, with its ends 3 projecting through a connection nozzle 7 welded to the vessel 1. A detachable closure 4 covers the end 3. Rings 9 and 11 are welded to the nozzle 7 and surround the end of the header with slight clearances to support the end and permit both radial expansion and axial displacement. Grooves 10 around the ring 9 permit steam to enter an annular space 8. A further ring 14 is welded to the header and is joined to the ring 11 by a corrugated ring 13 which permits longitudinal movement of the header. The space on the inside of the ring 13 is in constant connection with the atmosphere through a gap 12. A ring 16 surrounds the ring 11 and drip water in the case of leakage of packing 17 on the cover can be easily detected by its issuing from between said rings. A nozzle 15 serves to remove condensate from the annular space 8. In a modification, the corrugated ring 13 may be replaced by a stuffing box; the packing of which would be resiliently pressed against the header by clamps linked to the connection nozzle.
