Title: Improvements in or relating to warp tension controls for slashing machines
IPC: D02H3/00
Filed: 1948-12-08
Abstract: 656,869. Warp tension control for slashing-machines. DOMINION TEXTILE CO., Ltd. Dec. 8, 1948, No. 31791. Convention date, Feb. 13. [Class 142(iv)] The tension of the yarns in a slashing machine is maintained constant by a device including a guide roller positioned between the beam and a compensating roller so that the direction of the yarn between the compensating and guide rollers remains almost constant regardless of the movement of the compensating roller. The yarn 12 at the delivery end of the slasher passes round rollers 20, 22, over a compensating roller 34, round a guide roller 36, and on to the beam 14. The roller 34 is mounted on a pair of bell crank levers 26, pivoted at 30, and movement of the roller 34 is transmitted by levers 46, 54, 62, 66 and links 42, 56, 64, 70, 76, 78, 90 to a friction clutch 104. A weight 60 urges the roller 34 against the pull of the yarn. Extra pull on the yarn moves the roller 34, allowing the clutch to slip.

Abstract: 195,425. Fowler & Co. (Leeds), Ltd., J., Wood, D., and Livsey, H. Nov. 28, 1921. Surface treatment with semi-liquid materials; cauldrons. - A road roller driven by an internal-combustion engine and provided with a tar boiler and tar - spraying nozzles has means for utilizing the exhaust gases from the engine (1) for heating the tar tank and the pump which delivers the tar to the spraying nozzles, the heat of the gases being, if necessary, supplemented in the case of the tar tank by a firebox in which a draught may be induced by the exhaust gases, and (2) for cleaning the spraying nozzles. An air compresser may also be used for the latter purpose and serves also to supply air during spraying to secure a better distribution of the tar. In the form shown, the vehicle is driven by a motor a. The exhaust pipe p of the motor passes, by way of a box p<4>, forming the base of a pump m which serves to deliver tar from a tank p<5> through a pipe r to the spraying nozzles s, to an arrangement of connected exhaust boxes p<1>, p<2>, p<3> in the bottom of the tar tank p<5>, and finally delivers into the air at z. A branch pipe p<6> leads from the outlet pipe z to a jet in the uptake w from a fire-box beneath the tank, the arrangement producing a forced draught through the fire-box when the outlet z is closed by a flap-valve. The, exhaust gases may be passed through a branch pipe p<7>, having a cock o, to the tar-delivery pipe r to clean this pipe and the nozzles s. Air may also be supplied to the nozzles, to clean them or to secure a better distribution of tar, by means of a compressor t driven by the motor a, the air passing through the pipe v to an equalizing cylinder u and thence to the nozzles through a pipe v<1>.

Abstract: 1421130 Coating compositions HARLOW CHEMICAL CO Ltd 15 Nov 1973 [16 Nov 1972 9 July 1973] 53001/72 and 32517/73 Headings C3P and C3G Pigmented surface coating compositions which comprise an aqueous polymer latex or dispersion are provided with improved wet adhesion properties by the presence in at least one of the components of the composition of groups which are derivable from the reaction between a carbonyl group and a hydrazine of the formula wherein Q 1  represents H or a monovalent hydrocarbon radical (including alkyl, cycloalkyl, aryl, aralkyl and alkaryl radicals) which may optionally be substituted with substituents such as halogen, hydroxy, ether, ester or nitro groups. The stated groups may be incorporated into the latex polymer or may be present in a different component of the latex (or dispersion). When the groups are incorporated in the polymer, they may be produced by reacting a suitable hydrazine compound, e.g. hydrazine or methyl hydrazine) with carbonyl groups of the polymer or a monomer precursor thereof. Particularly suitable carbonyl-containing polymer components (or precursors) are those of oxohydrocarbon - substituted unsaturated amides, e.g. acrylamide derivatives of the formula where R 1  is H, alkyl or R 2  is as defined for R 1 ; R 3 , R 4 , R 5 , R 6  are independently H or a monovalent hydrocarbon radical; and R, is a monovalent hydrocarbon radical, such as diacetone acrylamide, diacetone methacrylamide, diacetophenone acrylamide and di-(methyl ethyl ketone) acrylamide. Other useful carbonyl components for the latex polymers include 1,1-dimethyl-3-oxobutyl acrylate, methyl vinyl ketone, acrolein, crotonaldehyde, cinnamaldehyde, vinyl acetoacetate and unsaturated keto- and aldehyde-terpenes. Instead of incorporating the stated groups in the latex polymer, they may be incorporated in a water-soluble polymer additive for the latex or in an auxiliary latex polymer. The stated groups may also be incorporated into a simple carbonyl compound such as acetone, methyl ethyl ketone or diacetone alcohol. The amount of the stated groups incorporated into the latex may be such that the nitrogen content is from 0À01 to 1% by weight based on latex solids. The latex polymer may be based on such monomers as acrylate or methacrylate esters, vinyl acetate and other vinyl esters, and styrene. In addition to pigments, the latex coating compositions may also include other additives such as extenders, thickeners, dispersing agents, wetting agents, defoamers, solvents and plasticizers. In Example 1 a polymer latex containing carbonyl groups modified by a hydrazine is prepared by (a) emulsion polymerization of n-butyl acrylate, methyl methacrylate and methacrylic acid and (J) graft polymerizing methyl methacrylate and diacetone acrylamide hydrazone on to the copolymer latex from (a). The graft polymer latex has added thereto titanium dioxide, talc, carboxymethyl cellulose, defoamer, fungicide, bactericide; dispersing agents and coalescing solvent.
