Title: Improvements relating to apparatus for contacting a continuously-moving thread with liquid
IPC: D01D1/06
Filed: 1949-11-02
Abstract: <PICT:0689770/IV (a)/1> <PICT:0689770/IV (a)/2> <PICT:0689770/IV (a)/3> <PICT:0689770/IV (a)/4> Apparatus for contacting a continuously-moving thread with a liquid comprises:-a vessel having bottom, side, and end portions, each of the end portions having an opening or slot for the passage therethrough of the moving thread; a trough-like member positioned within the vessel and spaced from the end portions but in alignment with the openings therein, the walls defining the trough-like member being provided with a plurality of spaced apertures extending longitudinally from one end of the trough to the other; an inlet reservoir beneath the trough; means for introducing liquid to the inlet reservoir; and means for withdrawing liquid from the vessel after its passage through the apertures of the trough-like member.  The apparatus may be arranged to maintain an artificial thread in contact with a softening liquid while it is being stretched in travelling between a pair of rollers.  It may be used in carrying out the process of Specification 689,742.  As shown in Fig. 1, a thread 26 comprising filaments of an acrylonitrile polymer, obtained by a wet-extrusion process, passes from the coagulating bath to a godet 38 and auxiliary roller 39.  It then passes through hot water contained in trough 42 and thence round godet 44 and auxiliary roller 45. Godet 44 has a greater peripheral speed than godet 38 so that the thread is stretched.  The thread then passes to a bobbin 50.  As shown in Figs. 5 and 6, the V-shaped trough portion 54 of the liquid-treatment vessel 42 has openings 66. Liquid 40 enters the vessel through conduit 60 and is forced through openings 66.  It flows along the trough 54 into collecting reservoirs 68, 70 located at each end, and then through conduits 62, 64 to a supply reservoir.  The liquid may be heated by electrical or other means, and the vessel 42 may be heat-insulated.  The vessel 42 is arranged so that the thread enters just above the bottom part of the U-shaped slot 56 in one of the end walls and, after travelling through the liquid in the trough 54, leaves through the U-shaped slot 56 in the other end wall.  After being stretched, the thread may be treated with an aqueous liquid containing an anti-static agent. Wetting agents and lubricants may also be included in the liquid finishing composition which may be applied to the thread by means of a vessel similar to the vessel 42.  As shown in Fig. 3, the thread is stretched while travelling through liquid contained in trough 42 and is passed continuously from the stretching godet 44 through trough 94, where it is treated with a liquid containing an anti-static agent, then over drying rolls 76, and thence to a twisting and winding device 84.  Specifications 594,999 and 672,775 also are referred to.

Title: Improvements in respiratory masks combined with a helmet
IPC: A62B18/04
Filed: 1937-04-03
Abstract: 491,609. Respiratory masks. CHARBONNEL, P. April 3, 1937, Nos. 9497 and 9498. Convention dates, April 3, 1936 and March 27, 1937. [Class 81 (ii)] A respiratory mask, for military or civil purposes, is normally disposed in the space 3 between the walls 1 and 2 of a double-walled helmet, but is adapted to be pulled out, through a crescent-shaped opening left between the edges of the walls at the front of the helmet, when required for use. Said opening may be closed by a cover provided with a lightning fastener 32, when the helmet is not in use. The facepiece 10 of the mask and the helmet may be made of moulded material mainly composed of synthetic resin. The face-piece 10 is connected by a pair of links 7 to a carriage 5 slidable on curved guides 4 arranged within the space 3, the carriage being normally retracted by rubber cords 6. In the form shown in Figs. 1 and 2, the links 7 also carry a curved member 8 having a rubber pad 8b adapted to fit on the forehead, while rubber side pieces 11, secured to the face-piece 10, are hinged about a pin 8a and are adapted to fit under the chin and on the cheeks. The part 10 is fitted with eyepieces 12 of unbreakable glass and with an exhaust valve 13. On pulling out the mask, downturned flanges on the parts 11 engage in upwardly-opening grooves 20 formed in the helmet wall 1, and the mask is tilted so that a rubber border 15 at the upper part of the part 10 engages in a downwardlyopening groove 16 on the wall 1. The space 3, which is thus in communication with the space between the mask and the face, communicates through an inlet valve 25 with a chamber 26 closed by a hinged cover 27 and containing a filter pad 30. Air is drawn in through an orifice 31 passes through the pad 30 and through the valve 25 into the space 3 whence it passes to the nose past the eye-pieces 12, thus tending to prevent the formation of mist on the latter. The cover 27 is held closed by a hook 28 fastened by a movable ornamental grenade 29. A ventilating opening 21 in the inner wall 2 is closed by a spring-urged valve 22 when the mask is in use, but, when the mask is retracted into the space 3, the valve 22 is opened by a nosepiece 24 carried by the member 8. In the form shown in Fig. 6, air is led through the valve 25 from the filter chamber 26 to the space between the mask and the face by an extensible corrugated tube 35, said space being no longer in communication with the space 3, but being sealed therefrom bv an elastic forehead band 40 secured to the face-piece 10 and side pieces 11. Tension cords 41 apply the band 40 on the forehead, and the mask is held in its operative position by the border 15 engaging the groove 16. According to the Specification as open to inspection under Sect. 91, the ends of the pad 8b are connected to the parts 11. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to methods and apparatus for producing pure boiler feedwater
IPC: B01J39/04
Filed: 1954-04-02
Abstract: 754,745. Feedwater supply systems. MONTECATINI SOC. GENERALE PER L'lNDUSTRIA MINERARIA E CHIMICA. April 2, 1954 [April 2, 1953], No. 9744/54. Class 123(2). The feedwater for a boiler fired with a gaseous fuel which contains a substantial proportion of hydrogen, for example methane or water gas, is obtained independently of external sources by condensing water vapour from the combustion gases leaving the boiler and, after its filtration and degassing, utilising the water thus obtained as feed water for the boiler. The combustion gases are diverted from the boiler outlet flue 1 by a baffle 3 having an adjustable by-pass damper 4 into a condenser-collector chamber 2 locating a coil 5 through which circulates cold water, for example, condensate. The water vapour in the gases condenses and collects in vessel 2 whence it passes to a storage tank 6. For boilers operating at a pressure of less than 60 atmospheres, the water is drawn from tank 6 by a pump 7 and flows through a filter press 8 for the removal of solid matter, a heater 16 and a degassing device (not shown), to the feedwater tank. When the operating pressure exceeds 60 atmospheres and substantially complete purity of the feedwater is required, the water from filter 8 flows through a cationic exchanger 12 for the removal of metallic ions, a degasser 13, a second pump 14 and an anionic exchanger 15 for the removal of silica, then flowing through the heater 16 to the feedwater tank.

Title: Improvements in and relating to coating compositions
Inventor: SMITH JOHN LIBERTY
IPC: C09D151/00
Filed: 1964-03-07
Abstract: Coating compositions are made by mixing hexamethoxymethyl-melamine with a solution, in a solution of a base, of a copolymer made by copolymerizing an acrylic or methacrylic ester, an unsaturated carboxylic acid and a further monomer different therefrom in an amount of up to 50% of the total monomers in the presence of an aqueous solution or dispersion of an alkali-soluble copolymer of an acrylic or methacrylic ester. Monomers specified for copolymerization with the ester and acid are styrene and its derivatives, vinyl acetate, butadiene, isoprene, hydroxyethyl acrylate, ethoxyethyl methacrylate, acrylamide, methacrylamide, methylol acrylamide and acrylonitrile. The examples describe making coating compositions by the aqueous emulsion copolymerization of methyl acrylate, styrene and methacrylic acid in the presence of sodium lauryl sulphate, a mercaptan and sodium and potassium persulphates, with gradual addition of monomers as the reaction proceeds, followed by the copolymerization in the resulting copolymer dispersion of differently proportioned mixtures of the same monomers.  The copolymers are then dissolved in ammonia and titanium dioxide and hexamethoxymethyl melamine are added thereto. The compositions are applied to metal surfaces and then stoved.ALSO:Mild steel panels and chromated aluminium foil are coated by applying thereto a mixture of hexamethoxymethyl melamine and a basic solution of a copolymer prepared by copolymerising an acrylic or methacrylic ester, an unsaturated carboxylic acid and another monomer in an aqueous solution or dispersion of an alkali-soluble copolymer of an acrylic or methacrylic ester (see Division C3).  The Examples describe the use in coating of ammonia-solutions of copolymer mixtures derived from methyl acrylate, stepene and methacrylic acids, the solutions containing titanium dioxide and hexamethoxymethyl melamine.  After application to the metal surfaces, the compositions are stored.
