Title: An improved process for the manufacture of carbon disulphide
IPC: C01B31/26
Filed: 1927-02-11
Abstract: 265,994. Komlos, J., Komlos, A., and Engelke, E. F., (Assignees of Vajdaffy, A. von). Feb. 16, 1926, [Convention date]. Carbon bisulphide; sulphuretted hydrogen; hydrogen cyanide; sulphocyanic acid. - Carbon bisulphide and sulphuretted hydrogen are produced by interaction at elevated temperature of sulphur or metallic sulphides with hydrocarbons, particularly those of the acetylene series, with or without the use of contact substances, such as carbon, metals or metal oxides or compounds. The reaction takes place at 380-450‹ C. when free sulphur is used, and at 500-850‹ C. in the case of metallic sulphides. Acetylene may be burned in sulphur vapour or vice versa or acetylene may be brought into contact with sulphur heated nearly to boiling point. Acetylene and gas purifying material may be passed through a heated tube in countercurrent. Carbon bisulphide is separated from the issuing gases, and the remaining sulphuretted hydrogen is absorbed in the residual de-sulphurized material which is discharged from the tube, thus producing further raw material. Pyrites and also various low-grade sulphur-containing earths may be utilized in the process. The Specification as open to inspection under Sect. 91 (3) (a) describes also the use of organic compounds other than hydrocarbons and states that hydrocarbons of high molecular weight and their sulphur derivatives are obtained as by-products. When nitrogen or nitrogen compounds such as ammonia are present or when organic nitrogen compounds are used, hydrocyanic and sulphocyanic acids are obtained. This subjectmatter does not appear in the Specification as accepted.

Abstract: 389,253. Insulator pins. ROST, H.,- 170, Calle Patzcuara, Mexico City. Feb. 11, 1932, No. 4114. [Class 36.] A resilient pin for attaching an insulator to a cross arm &c. is made from a steel strip which is bent to form two upright shanks connected together at their ends by horizontal members, the shanks being screw threaded near their upper ends for engagement with a screw-threaded cavity of the insulator and being of such width that their edges do not touch when the pin is inserted within the insulator. The thread on the pin is preferably of slightly greater diameter than that of the insulator cavity so that the pin engages the insulator under pressure. To increase the resiliency of the pin the shanks may taper in width or thickness away from the base of the pin. Fig. 1 shows a pin formed from a steel strip 1, bent to.provide a base 9 having upwardly extending shanks 3 which are provided near their upper ends with screw threads 4. The extremities 5 of the shanks are of reduced width and are bent inwardly and soldered together to form the top 7 of the pin. An aperture 10, through which a fixing bolt may be passed, is formed in the base 9. In a modified construction, the top of the pin is formed by a washer which is soldered across upright extremities of the shanks 3. In another construction, Figs. 3 and 4, the strip 1 is bent to form a top 3 having depending shanks 4, the lower extremities of which are bent inwardly, twisted sidewise and soldered together with their edges abutting to form a base 8 for the pin. Fig. 8 shows a pin modified for use with an insulator having a cavity of narrow bore, in which the upper extremities of the shanks are laid side by side and soldered or spot welded together. Such a pin may be used for supporting insulators of larger bore by interposing between the pin and the insulator cavity a longitudinally split tubular adaptor, preferably of annealed aluminium, which is threaded internally to receive the pin and externally to fit the bore of the insulator.
