Title: Anchorages for cables
IPC: E21B19/00
Filed: 1940-08-15
Abstract: 542,735. Cable anchorage. NATIONAL SUPPLY CORPORATION, and OIL WELL ENGINEERING CO., Ltd. Aug. 15, 1940, No. 13058. Convention date, March 5. [Class 78 (ii)] The dead end of a cable is held by a releasable clamp 15 adjacent to which is a stationary drum 7 about which the first portion of the active part of the cable 14 passes. The anchorage is more particularly intended for rotary well-drilling rigs, and sudden slackening and tautening of the cable will have its tugging effect on the clamp 15 lessened by the friction of the loops of cable about the drum 7. Latches 26 are pivoted to one flange 11 of this drum, and have each an automatic catch engaging the other flange 12 when the latch is turned over to bridge the drum groove. Sufficient of these latches are provided to retain the loops on the drum 7 when undue slackening of the cable takes place, and they are located when closed near enough to the groove base to prevent one loop riding over another. The clamp 15 consists of two grooved plates gripping the cable between them under screw-and-bolt pressure, and the groove may be plain or shaped to fit the twist, &c. of the cable. The clamp 15 is located so that the issuing cable is t ingential to the entering portion of the drum groove, and clamp and drum are mounted on a foot 3 carried by a girder 4 and grounded by links 5, 6. Surplus cable is stored on a rotatable drum 18 to allow of locations of stresses in the cable'to be changed periodically.

Abstract: 332,944. Elkington, H. D., (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). April 27, 1929. Mineral oil's, purifying.-Mineral oils containing sulphur are refined by heating them with hydrogen in the presence of a colloidal molybdenum compound absorbed in or distributed on a finely divided material, e.g. absorption carbon, the reaction conditions being such that no substantial splitting of the materials takes place. The molybdenum catalyst may be prepared by dissolving 15 grms. of ammonium molybdate in 400 ec. water and adding 100 cc. of sulphuric acid of strength 4N. The solution is heated and reduced with hydrogen sulphide, and 40 gs. of " Carboraffin " are added to the blue colloidal solution formed, whereupon the solution is decolorized and the molybdenum carbon mixture is filtered off and dried. A blackish brown gas oil contaning 2.9 per cent sulphur was heated with hydrogen under pressure to 380‹ C. in the presence of the catalyst prepared as described above, the temperature being maintained for 15 minutes at 380‹ C. under a pressure of 90 kg. per sq. cm. A product having the characteristic of a lubricating oil was obtained containing only 0.75 per cent of sulphur. Specification 315,439 is referred to.

Title: Improvements in and relating to the manufacture, production and treatment of artificial threads, filaments and the like
IPC: D01D10/04
Filed: 1931-05-12
Abstract: For the continuous treatment, washing and drying of artificial filaments, threads, &c., the latter on leaving the precipitation bath are wound in the form of a helix on a rotating drum or cage comprising two sets of longitudinal bars, one series being eccentric to the other series and mounted in the manner described below so that the thread is moved along the drum, while each turn of the thread maintains a substantially constant diameter.  The drum may be cylindrical or it may be tapered either as a whole or in part so as to enable the threads to be stretched or to compensate for any elongation in their length during treatment. To enable the drum to move forward the turns of the thread, the two series of bars constituting the drum are capable of relative axial and radial movement.  Thus, the bars 28, 29, Fig. 2, which may be hollow and of resistant metal, are arranged to alternate in position and are loosely connected by wires to pins 32 projecting from pairs of discs 30, 31 and 34, 35; the discs 30, 31 are inclined to the general axis <PICT:0378467/IV/1> <PICT:0378467/IV/2> of the drum and are mounted on and are driven by inclined shafts 36, 38 connected by a shaft 37; the discs 34, 35 are mounted on bearings on the brackets 40 and are oppositely inclined with respect to the discs 30, 31, and further the axes of the pairs 30, 34 and 31, 35, although approximately in the same plane, are displaced laterally; the frame constituted by the bars 29 and discs 34, 35 is rotated by contact between the bars 28 and the bars 29.  For use as in the manufacture of cuprammonium silk, the threads 11, Fig. 1, leaving the caustic soda precipitating bath, are led on to the drum 15, which is preferably inclined, and the liquids necessary for the treatment are preferably allowed to drop on to the drum from pipes 21, 23, being collected in a trough 26 fixed below; acid is fed to the pipe 21, and water for washing to the pipe 23, and the threads pass finally under a blast of warm air from a pipe 25; on leaving the drum the lined threads are collected on the winding device 18, 19, 20.  More than one thread may be wound on the drum, the several threads being maintained separate throughout the treatment.  For the purpose of collecting separately the treating and washing liquids, a number of suitably disposed troughs are provided and the outer surfaces of the bars 28, 29 are furnished with projecting ribs or with holes to cause the liquids to drop off, or the liquids may be removed by an air jet.
