Abstract: A coating composition comprises as an adhesive a functionally modified elastomer in latex form containing sufficient ammonium zirconyl carbonate to improve the wet rub resistance of the coating. A functionally modified elastomer is an interpolymer in which one of the comonomers bears a vinyl group and a functional group, e.g. carboxylic acid or hydroxyl group.  Specified are acrylic acid, methacrylic, acid, maleic acid, its anhydride, itaconic acid, hydroxy ethyl methacrylate, hydroxypropyl methacrylate and N-methylol acrylamide.  Specified elastomers are carboxylic and modified styrene, butadiene copolymer latices, and carboxylic acid modified acrylic latices.  Ureaformaldehyde resins, starchy clay, calcium carbonate, calcium stearate, titanium oxide, blanc fixe and satin white may also be present.ALSO:Ammonium zirconyl carbonate is prepared by reacting z oxychloride with a theoretical proportion of ammonium carbonate in aqueous solution containing a little ammonium hydroxide, e.g. 1% on the ammonium carbonate.  The reaction may take place by dumping the z. oxychloride into a 20-30% ammonium carbonate solution containing a little of 28% ammonia water.  The resultant solution contains 5.75% solids w.r.t. z. oxide content and in addition to the a.z. carbonate, ammonium chloride is formed.  The z. oxychloride may be replaced by other soluble z. salts, e.g. z. sulphate, but the oxychloride gives best results.ALSO:Paper is coated with a composition comprising as adhesive a functionally modified elastomer in latex foam containing sufficient ammonium zirconyl carbonate to improve the wet rub resistance of the coating.  A functionally modified elastomer is an interpolymer in which one of the comonomers bears a vinyl group and a functional group.  Examples of elastomers are carboxylic acid modified styrene butadiene latices and carboxylic acid modified acrylic latices.  The proportion of ammonium zirconyl carbonate in the composition may range from 0,5-20% by weight of latex solids.  In examples, an aqueous dispersion containing 60% solids and containing 100 parts dry clay and sufficient latex to give 1,5 parts of expolymer has added thereto (a) 10% commercial ammonium zirconyl carbonate (1,5 parts dry), (b) 20 parts of a carbonate solution (1.15 parts dry), and (c) a solution containing 0,86 parts of the carbonate and 1 1/2 parts urea formaldehyde.  Each coating is applied to a sized raw paper stock and part air-dried and part oven-cured at 200  DEG F.  Other examples vary the ingredients and their proportions.

The member 7 is carried by a tripod 13 having legs passing through flow holes in the seat and a pin 15 passing through a filter and engaging a rod 33 The rod 33 passes through a tube 31 secured at its lower end to a spring abutment 28 and at its upper end to a piston 32 slidable in a pressure relief valve member 38 urged by a spring 57 which abuts a bridge-piece 54 carried by the rod on to a seat 37 formed on the casing part 30. The bridge-piece engages a helical groove 55 in the casing part 30 and on rotation of a control knob 42 through 90 degrees from its inoperative position pins 53 secured to the knob rotate and axially move the bridge-piece to hold the valve 38 more firmly on its seat and through the rod 33 and pin 15 unseat the valve 7, whence compressed air from the container 22 passes through the valve 7, an annular resilient non-return valve 58 and holes 59 into the fuel container 21 to pressurize the fuel therein and force it out through a nozzle to be ignited. On the pressure in the container 21 and the tube 20 building-up, the piston 32 is moved upwardly against its loading spring 27 to permit the valve 7 to move towards closure to regulate the supply of compressedair to the container 21. At this stage the valve 38 remains seated, the pressure load acting on the upper face of a flange 39 of the valve member 38 being greater than that acting on the lower face thereof. On the pressure in the container 21 becoming excessive, the piston 32 abuts a plate 41 to compress the spring 57 and unseat the valve 38, the air finally exhausting to atmosphere through an annular resilient flap valve 52. A light return spring 34 surrounding the rod 35 urges the rod and the valve member 7 downwardly when the pressure in the container 21 falls. On the disconnection of the casing parts 23, 23a, 30 from the body member 1, the valve 7 closes the container 22 and the valve 38 the container 21. Specification 716,638 is referred to.
