Title: Fire-resistant polyesters
IPC: C08G63/58
Filed: 1955-11-16
Abstract: Fire-resistant polyesters containing 20-50 per cent by weight of combined chlorine are made by polyesterifying (a) tetrachlorophthalic or hexachloroendomethylene tetrahydrophthalic acid or anhydride with (b) trichlorophenyl-, tetrachlorophenyl-, or pentachlorophenyl-monoglyceryl ether or an epoxide thereof. Part of the chlorinated acid may be replaced by succinic, adipic, maleic or phthalic acid and part of the chlorinated alcohol may be replaced by ethylene glycol, diethylene glycol, 1,4-butanediol, 1,4-butenediol, 1,4-butinediol, glycerine or trimethylol propane. Rubbers are made by reacting the hydroxyl terminated polyesters with excess diisocyanate and a cross-linking agent (e.g. water, ethylene glycol or ethylene diamine).  Foams are made by reacting the carboxyl or hydroxyl terminated polyester with a polyisocyanate and water, preferably in presence of a tertiary amine and a surface-active agent; foaming may be effected in presence of antimony oxide which enhances the flame-resistance. Coatings, lacquers and films are made if the polyester is reacted with a polyisocyanate (which may be in the form of a mixture of trimethylol propane and toluylene diisocyanate) in an inert solvent (e.g. butyl acetate, ethyl acetate, toluene and glycol-monomethyl ether acetate), the solution applied to a supporting material and the solvent removed.  The polyesters which contain ethylenic unsaturation due to the incorporation of an unsaturated polycarboxylic acid and/or an unsaturated polyhydric alcohol may be copolymerized with styrene, methyl methacrylate, diallyl phthalate or tetrachlorophthalic acid diallyl ester. Copolymerization may be effected in presence of a peroxide (e.g. benzoyl, cyclohexanol or di-tert.-butyl peroxide or cumyl hydroperoxide) which may be employed in combination with cobalt naphthenate, cobalt chloride, manganese naphthenate or dimethyl-p-toluidine.

Filed: 1935-11-27
Abstract: 462,403. Fluid-pressure horns; fluid supply. TRICO PRODUCTS CORPORATION. Nov. 27, 1935, No. 32863. Convention date, April 18. [Class 13] In a horn system of the kind in which the operation of the horn is controlled by a valve adapted to be actuated by pneumatic means and in which a plurality of horns is provided, a single common actuator is employed for selectively controlling the application of the said pneumatic means to the control valves of the horns. The control valves 21, 22 are actuated pneumatically under control of the driver and the horns 14, 20 are operated by air passing to the intake manifold 11 through a chamber 16. Secured on the steering column 12 is a casing 25 in which is mounted a spring-pressed member 42, Fig. 3, having a flange 41 which normally seats on a shoulder 31 and closes the opening 28 of the casing 25 to the atmosphere. The member 42, which is integral with an actuating lever 39, engages spring-pressed ballvalves 34, 35, Fig. 4, and may be rocked by the lever 39 to open one or the other or both of the valves 34, 35 to allow air to pass to the associated conduit 23 or 24 or both conduits to control the valves 21, 22, which are mechanically similar but may be of different dimensions. If, for example, the horn 20 is to be sounded, the control lever 39 is rocked so that air passes through the conduit 23 leading to a chamber 55 in the valve 21, Fig. 6. A diaphragm 56 moved to the left carries a pin 69 which opens a valve 65 so that air passes through the horn 20, pipe 18, valve opening 58 to a passage 57 connected to the chamber 16. When the operating lever 39 is moved to its inoperative position, the air in the chamber 55 leaks past an adjustable needle-valve 64 and the valve 65 closes under the action of a spring 66. A bleed-vent 68 which is opened to the atmosphere when the valve 65 is closed prevents the horn from sounding on account of leakage past the valve.

Abstract: 325,485. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 12, 1928. Azo dyes and soluble metal compounds thereof. - Azo dyestuffs are obtained by coupling diazotized aminosulphosalicylic acids with such monooxybenzenes, containing not more than one further nucleus (and excepting naphthols), as are free from carboxylic and unsubstituted amino groups and are substituted in p-position to the hydroxy group. Specified phenols' are p-cresol, hydroquinone monomethyl ether, 2 : 4-dimethylphenol, p - hydroxydiphenylmethane, 4 - acetylaminophenol, and p-chlor-m-cresol. The products dye evenly and have good fastness to light, and the metal compounds obtainabe therefrom by treatment in substance, in the dyebath, or on the fibre, with agents yielding metal have increased fastness' properties. The following examples are specified. (1) The dyestuff p-aminosulphosalicylic acid (COOH : OH : NH2 : SO3H=1 : 2 : 5 : 4) # p-cresol dyes wool yellow, and its chromium compound produced in substance, in the dyebath, or on the fibre gives dyeings very fast to washing, fulling, and light. (2) The dyestuff p-aminosulphosalicylic acid # 2 : 4-dimethylphenol gives on wool a redder dyeing than the dyestuff of example (1); its chromium compound gives very even dyeings, fast to washing and fulling and is suitable for dyeing leather; its copper compound dyes wool yellow. o-Aminosulphosalicylic acid (COOH : OH : NH2 : SO3H=1 : 2 : 3 : 4) is also specified as diazo component giving redder shades than the p-aminosulphosalicylic acid. Reference has been directed by the Comptroller to Specifications 2468/99, 13204/15 and 269,934.

Abstract: 604,184. Gun sights. NASH, A. F. Nov. 28, 1935, No. 33070. [Class 92 (ii)] Sighting mechanism, for use on aircraft and of the kind which provide corrections allowing for the speed of the aircraft, is provided with a cam member or members and means contacting them when the gun is moved in azimuth or elevation for effecting the required relative displacement between the gun and sight. The frame 2 of the sight 1 pivots about a vertical axis in an arm 5 extending from a member 6, and this member pivots about a vertical axis on a bracket 9a secured to a cross-member 10. The member 10 extends between arms 11, which pivot about a horizontal axis in standards 13, 14, and with the latter are associated sprockets 15, 17, to which motions are imparted when the gun is moved in elevation and azimuth respectively. Rotation thus imparted to the sprocket 15 and thence to arms 11 causes the rotation of an arm 19 which serves to rock a shaft 21, a lever 23 on which then causes the lifting of a rod 24. This rod extends to a solid cam fitted within the member 6 and a follower 27 of the cam is connected by an arm 28 and linkwork to cause the required elevating movement of the sight when the cam is lifted by the rod 24. Rotation of the sight in azimuth is effected by a link 49 connected to a pivoted element 38 associated with a second cam follower 36. Relative movement between the cam and this follower is effected by rotating the member 6 when the gun is moved in azimuth, such rotation being produced by lever 55, link 53, and other mechanism including a cylindrical rack 63 for coupling the member 6 to the sprocket 17.

Oct. 31, 1929, No. 33186. Convention date, Dec. 31, 1928. [Class 35.] Alternating-current motors; machines with unwound iron armatures; machines with two or more armatures; motors, controlling.-A gramophone is driven by an alternating-current motor which gives a high torque for starting and a synchronous type of motor which gives a high torque at a predetermined running speed, the two motors acting on a common shaft coupled to the record carrier through a yielding connection which, together with the flywheel action of the carrier, damps out hunting in the motors. The arrangement shown comprises a disc induction motor 1, Fig. 3, and a notched iron rotor synchronous motor 9 running on single-phase mains 5, 6. The induction motor stator coils 3, 4 are supplied through a phasesplitting condenser 7 and the synchronous motor has a three-phase winding 11 fed through unequal phase-splitting condensers 12, 13, an additional condenser 14 being used in one main to tune the motor circuit to a frequency a little above that of the supply for preventing hunting in the manner described in Specification 288,236, [Class 35, Dynamo-electric generators &c.]. The coils 3, 4 are on opposite sides of the disc 2, as shown in Figs. 3 and 4 and are carried by the same framework 16, 17 as the stator coils 19 and slotted poles 20 of the synchronous motor. The two rotors are mounted on a common shaft supported on a ball 15 and coupled to the carrier 22 by a lost-motion device consisting of a transverse pin 23 engaging a slot in the carrier boss. The friction of this lost-motion device is sufficient to damp out the hunting which tends to appear especially at the speed when the synchronous motor comes into operation and gives the greater part of the torque required for driving the carrier at its normal running speed.
