Title: A process for the continuous production of rubberised tyre fabrics
IPC: C08J5/00
Filed: 1949-01-28
Abstract: 682,438. Rubberized cord fabric. DUNLOP RUBBER CO., Ltd., COWLES, W. A., GOUGH, V. E., and JONES, P. W. B. Dec. 29, 1949. [Jan. 28, 1949] No. 27280/51. Divided out of 682,383, [Group IX]. Class 140. A rubberized fabric is produced from filamentary materials having a high modulus of rigidity (i.e. materials which tend to snarl when withdrawn axially from bobbins) by, before rubberizing, withdrawing the materials axially from bobbins, after they have received a twist of one turn for each winding on the bobbin, the withdrawal being in such a direction that the twist is removed. The twist may be inserted into the material by the apparatus disclosed in Specification 682,383, [Group IX]. Preferred materials are steel cord, or rayon ccated with a resorcinal-formaldehyde resin and these may be employed as a weftless fabric in tyre carcasses. Bobbins of the prior twisted cord may be non-rotatably mounted on a calendar creel where, to permit the cords from two bobbins to run in series, the bobbins are mounted with their longitudinal axes slightly inclined to the vertical with a braking device located at the point of intersection of the axes. The starting end of the cord on one bobbin is welded to the finishing end of the cord of the other package so that continuous running is ensured.

Title: A method of preparing halogendi-substituted ethylenes
IPC: C07C17/02
Filed: 1954-09-21
Abstract: A process of preparing di-halogen substituted ethylenes comprises passing acetylene into an aqueous solution containing cupric halide, cuprous halide and hydrogen halide at 60 DEG  to 120 DEG  C. as described in the parent Specification, with the additional feature that the solution contains an alkali metal halide, or ammonium halide, or an alkaline earth metal halide, the halogen being chlorine or bromine, and the concentration of hydrogen halide being from 0.58 to 2.9 mols. per litre.  The total concentration of cuprous and cupric halides is from 2.0 to 4.0 mols. per litre, and the ratio of the total concentration of cuprous and cupric halides to that of the alkali metal, ammonium, or alkaline earth metal ions is between 1 : 0.8 and 1 : 1.5.  The process may be carried out at a pressure up to 1.5 atmospheres gauge pressure.  The molar ratio of Cu+ : Cu++ ranges from 4 : 1 to 9 : 1.  Mixtures of 1,1-dichloroethylene and trans-1,2-dichloroethylene, and the corresponding bromo compounds, are prepared by the process.  The cupric halide is reduced to curpous halide as the reaction proceeds, and the solution is reoxidized by passing oxygen, air, or free halogen into it, while adding hydrogen halide or hydrohalic acid to maintain the hydrogen halide concentration.  In examples, the solutions used contain, besides the cuprous and cupric chlorides or bromides and hydrogen chloride or bromide, (1) ammonium chloride, (2) potassium chloride, and (4) ammonium bromide.  The formation of a mixture of dihaloethylenes may be carried out continuously by passing acetylene up through the solution in a reaction tower, the product being removed at the top, dried and condensed, unchanged acetylene being returned to the reaction tower.  The solution in the tower is continuously withdrawn, boiled to remove dissolved acetylene and excess water, and passed to a tower where the cuprous halide is partially oxidized back to cupric halide by air, oxygen, or halogen passed through the solution and hydrogen halide as gas or solution added; the solution is continuously returned to the first reaction tower.  The process may be carried out discontinuously using two towers, one for the reaction and one for solution regeneration, or in one reaction tower, the solution being regenerated therein after the dihaloethylenes have been removed.
