Title: Process and apparatus for the manufacture of artificial filaments
IPC: D01D10/04
Filed: 1932-10-27
Abstract: <PICT:0394216/IV/1> <PICT:0394216/IV/2> Freshly spun filaments obtained from solutions of cellulose or of cellulose esters or ethers are passed from the extrusion apparatus to one or more pairs of rollers around which they are guided in a helical path and upon which they are treated with washing, bleaching, dyeing, sizing, or other liquids.  The rollers are disposed with their axes inclined to each other either in a common plane or in parallel planes.  The arrangement of the rollers ensures separation of the individual turns of thread.  When the axes are inclined in a common plane, the thread loops travel towards the geometrical point of intersection independently of the direction of rotation of the rollers.  When the axes are arranged skew fashion the direction of advance of the thread loops depends on the direction of rotation of the rollers.  As shown in Fig. 3, the thread loops travel in the direction of the arrow c when the rollers are rotating in the direction indicated by the arrows a. In this arrangement, advance of the loops is stated to take place while the thread is in contact with the roller surface, the thread being rolled or twisted temporarily.  As shown in Fig. 4, filaments 1 pass from the spinning cell 19, through a channel 4 supplied with acid, and then round the rollers 2, 3, which are inclined from the horizontal and disposed at an angle to each other in a common plane.  They are supported in bearings at one end only. Alternatively, the rollers may be arranged in a horizontal plane or the rollers for a series of spinning machines may be arranged in two horizontal rows.  The rollers may be driven in groups or together from one drive.  When the thread is first taken round the pair of rollers, the separate loops may be in contact but as the rollers rotate, the loops spread out.  If desired, a number of threads may be passed round the same pair of rollers.  As shown in Fig. 4, liquid is sprayed from pipe 31 on to the surface of the roller 3, but if desired one or both of the rollers may be arranged to dip into a bath of treating liquid. From the rollers 2, 3 the thread passes to the other side of the machine frame and is passed several times round a drying roller 33 and finally wound on spools 35.  If desired the threads may be twisted before being wound.  Specification 394,217 is referred to.

Title: Improvements relating to lubricating systems
IPC: F16N13/04
Filed: 1937-11-04
Abstract: 505,102. Force -- feed lubricating. LUCAS, Ltd., J. (Bijur Lubricating Corporation) Nov. 4, 1937, No. 30219. [Class 12 (iii)] Relates to lubricating means including a continuously driven pump, a. delivery duct through which lubricant can be supplied by the pump to a distributing system, a byepass through which lubricant can flow from the pump more freely than from the pump to the delivery duct, a valve controlling the byepass, and mechanically controlled means adapted at predetermined intervals to close the valve and thereby cause lubricant to be discharged by the pump through the delivery duct to the distributing system. According to the invention adjustable means are provided for regulating the quantity of lubricant discharged by the pump through the delivery duct when the byepass controlling valve is closed. A gearwheel pump 21, driven by the machine to be lubricated, or otherwise, draws from a reservoir r through a filter 25 and discharges to a port 31. The latter communicates by ducts 36, ball valve 38, and space. 39 with a byepass 41 leading to a chamber s from which oil is returned to the reservoir r. The valve 38 is controlled by a spring-pressed sleeve 16 surrounding a rod 17 supported by a spring 44. The sleeve 16 is normally held clear of the valve 38 by a lever 14 actuated by a cam 9. Periodically, a projection 15 on the lever 14 engages a notch 13 in the cam 9 and then the valve 38 closes and shuts off the byepass 41. The port 31 also communicates with a pipe 47 having two branches. One branch 60 leads to the system of pipes connected to the machine to be lubricated, and the other branch leads to the chamber s through a non-return valve 50 and an adjustable needle valve 52. Each part to be lubricated is fitted with a flow control fitting of the type requiring, for its operation, a substantial oil pressure. As the valve 38 is generally open the lubricant pumped by the pump 21 passes through the byepass 41 and is returned to the reservoir r. At predetermined intervals the valve 38 is held closed. A pressure is then built up in the lubricating system and oil is fed to the bearings. The quantity of oil fed is varied by adjusting the valve 52. The rod 17 has a finger button 45 so that the valve 38 may be closed manually when desired.

Title: Improvements in or relating to electric batteries employing cuprous chloride
IPC: H01M4/08
Filed: 1953-11-02
Abstract: 733,543. Batteries. SOC. DES ACCUMULATEURS FIXES ET DE TRACTION SOC. ANON. Nov. 2, 1953 [Nov. 19, 1952], No. 30249/53. Class 53. An electrode of a battery consists of sintered copper 2 the pores of which are filled with cuprous chloride. The sintered copper is supported on a perforated copper sheet 1 and is covered by a layer 4 of felted cotton fibres. The second electrode consists of a magnesium plate 6 covered with a layer 7 similar to the layer 4. A close cotton fabric 8 separates the electrodes and layers 4, 7 and all the elements are enclosed by two polyvinyl chloride trays 3, 5 the edges of which are welded together to grip the fabric 8 and electrode connections 9 between them. The cell is activated by the addition of water which is introduced through an opening which may be made in the casing when required. The copper electrode is made from electrolytic copper which is sintered in hydrogen on a perforated copper sheet. The sintered plate is impregnated with a solution of cupric chloride and is allowed to stand for several days out of contact with air. The metallic copper reduces the cupric chloride to cuprous chloride. Alternatively the sintered plate impregnated with cupric chloride may be made the cathode in an electrolytic bath of cupric chloride whereby cuprous chloride is formed in the pores of the plate. In another method of making the sintered plate the copper may be carried on a support which is destroyed, as by vaporization, during the sintering process. The support may be in the form of a band to which the copper to be sintered is applied in the form of paste. The band is dried and cut into the required lengths after the sintering and impregnating processes have been carried out.

Title: Improvements in Drive Transmission Devices
IPC: F16D25/08
Filed: 1967-06-30
Abstract: 1,196,130. Controlling friction clutches. FRANCAISE DU FERODO S.A. 30 June, 1967 [2 Aug., 1966; 20 April, 1967], No. 30386/67. Headings F2C and F2L. In a friction clutch which is engaged by a diaphragm spring and disengaged by an hydraulic servo piston acting on the inner periphery of the spring, a residual pressure is maintained in the servo cylinder when the clutch is engaged in order to maintain a thrust member carried by the piston in contact with the diaphragm spring. In embodiments in which the servo cylinder and piston rotate with the input parts of the clutch, the residual pressure may be provided by centrifugal force acting on the liquid remaining in the cylinder, and the piston is provided with vanes to assist in inducing the centrifugal pressure. In constructions in which the servo piston and cylinder are non-rotary, the residual pressure is produced by a backpressure valve in the exhaust line from the cylinder and the thrust member is mounted on the piston by way of a ball bearing. As shown, a control system for a clutch following an hydraulic torque converter 55 and having a rotating servo piston 33 comprises a control valve 85 positioned by a solenoid operated pilot valve 78. Liquid is supplied to the control valve 85 by a pump 72 at pressure determined by a valve 99, and in the clutch disengaged position shown liquid at this pressure is supplied to the clutch servo cylinder 31. On de-energizing the pilot valve solenoid, the pilot valve is shifted to the right by a spring and liquid is directed to the right hand chamber of the valve 85 to shift it to the left so that liquid is supplied to the torque converter 55 at a pressure determined by a valve 98, and the clutch engages. The rate of clutch engagement is controlled by a restriction 94 and a by-pass valve 95 which allows initial fast exhaust of fluid from the clutch servo cylinder until the valve 95 closes and the restriction 94 thereafter controls the rate of exhaust from the cylinder 31. A residual pressure is maintained in the cylinder by centrifugal force. In a modification (Fig. 6, not shown) the control valve is actuated directly by a solenoid, and the restriction and by-pass valve are incorporated in the control valve.

Abstract: 901,395. Making helically-seamed tubes; welding by fusion. KUCKENS, A. Dec. 23, 1958 [Aug. 2, 1958], No. 30522/60. Divided out of 901,391. Classes 83 (2) and 83 (4). [Also in Group XXXVII] An electrical control system for a machine for producing tubes with a helical weld seam formed by inside and/or outside welding is characterized in that the weld electrodes are included in a common electrical control circuit with the driving motors for the mechanical elements of the machine, in such manner that should one of the electrode arcs be extinguished the current supplied to the electrode supporting the other arc as well as the current to said driving motors is automatically cut-off. A selector switch 51 is provided so that in position I only an electrode Ei is used, for internal welding of the helical seam, in position II both electrodes Ei and Ea are used, for both internal and external welding, and in position III only the electrode Ea is used, for external welding. In operation a switch 55 is closed to bring a severing device for the completed tube into operation and to close a switch 56b so that the main driving motor (not shown), for feeding strip into helically-seamed tube forming means, may later be allowed to start. With switch 51 in, say, position II a switch 67 is closed to energize a coil 66, relay coils 65, 71 and relay coils 58, 59. A timing device 66a is brought into operation and connects a coil 70 which operates supply contacts to current for the main driving motor after the electrode arcs have been struck. During welding a holding coil 54 for the main drive motor is held in operation by the welding current relay 65 or 71 and if a welding arc is interrupted the holding coil is released by failure of its corresponding welding current relay 65 or 71 and the whole plant is brought to a standstill and the welding current of the electrode still in operation is automatically stopped. A current responsive relay 72 (or 76) and a voltageresponsive relay 73 (or 77) operate contacts operating coils 74, 75 (or 78, 79) which actuate regulating motors M for welding current sources G so that variations in welding current strength and voltage may be automatically adjusted.
