Title: Methods of and apparatus for electrolytically cleaning or descaling the internal surface of a hollow metal article, such as the internal surface of a hollow metal valve
IPC: C25F7/00
Filed: 1944-03-14
Abstract: 611,610. Electrolytic cleaning. THOMPSON PRODUCTS, Inc. March 14, 1944, No. 4721. Convention date, April 9, 1943. [Class 41] [Also in Group XXVII] The internal surface of a hollow metal valve is descaled electrolytically to form a surface having a high rate of heat transfer to the metal coolant such as sodium. The valve 14 is fixed vertically in a clamp 13 from which it is insulated at 19 and a hollow conductor 25 passes down the valve stem through insulating spacers 28, 29 and clamp 26 insulated at 27 which hold it respectively inside and outside the valve. Also passing through spacers 28, 29 is a wire 41 which is connected at its lower end to the end of the tube 25 by two wire links 37, 38 hinged at 36, 39, 42. By pulling up the upper end of the wire 41, links 37, 38 are collapsed into a straight-line position (Fig. 3), thus allowing their insertion into and removal from the valve 14 with the tube 25, or extended into the position shown in Fig. 2, which conforms with the internal shape of the valve head 15. An electrolyte which may be an aqueous solution of orthophosphoric acid, is passed from a reservoir (not shown) down the tube 25 and overflows, passing through apertures 32, 31 in spacers 29, 28. A positive connection 47 is made to the valve 14 which forms the anode and current passes through the electrolyte to the links 37, 38 which form the cathode and together with wire 41 are of stainless steel, and thence along the tube 25, which is coated with a stop-off lacquer to prevent electrolytic action at its surface, to a negative connection 48. To produce an even descaling of the valve head relative rotation is arranged between the valve and cathode, preferably by rotating the valve through about 45 degrees every 5 minutes. After emptying and washing the surface will be bright but pitted, and for polishing a small current might be used as described more fully in Specification 611,609. Sulphuric acid or a mixture of sulphuric and phosphoric acids may be used as electrolytes whilst the valve may be made of alloys containing nickel, chromium, iron, molybdenum, cobalt or tungsten. Instead of D.C., interrupted D.C. or A.C. may be used.

Title: Improvements in and relating to the manufacture of viscose
Inventor: WEIGHAM WILLIAM REGINALD
IPC: D01F2/08
Filed: 1952-02-25
Abstract: In the production of viscose, cellulose xanthate and dilute aqueous caustic soda solution are mixed at a temperature higher than that at which the viscose is to be aged, and after such mixing the viscose is de-aerated and simultaneously cooled to the desired ageing temperature by boiling it under reduced pressure p  while flowing in one or more thin sheets, e.g. in a continuous de-aerator of the type described in Specification 729,440.  In the example, cellulose xanthate and aqueous sodium hydroxide solution are mixed in a mixer in which the temperature is allowed to rise (due to the power input) to about 23 DEG  C., the ambient temperature being 16-18 DEG  C., after which it is maintained at 23 DEG  C. by circulating a cooling liquid through the mixer jacket.  The viscose is then passed through a continuous deaerator, of the type described in Specification 729,440, which is maintained under a pressure sufficiently reduced to cause the viscose to boil and cool to about 18 DEG  C.  The de-aerated viscose is passed by way of a filter to a series of storage tanks in which it is aged at about 18 DEG  C. and, after ageing, is passed through a second de-aerator of the same construction and operation as the first before delivery to a spinning-machine.  Specification 554,188 and U.S.A. Specification 2,573,978 also are referred to.

Filed: 1928-02-17
Abstract: 286,292. I. G. Farbenindustrie Akt.- Ges. March 4, 1927, [Convention date]. Apparatus for making filaments. - To obtain artificial silk having a uniform capacity for being dyed, a tension is applied to the incompletelyconverted thread by bending it between the spinning nozzle and the receiving device in a thread guide which is mounted resiliently so that the tension is maintained constant. The guide may be resiliently mounted by means of an elastic band or a helical spring. The tension to which the thread is subjected depends on the strength and extensibility desired in the product; a thread exhibiting even dyeing qualities is still obtained when the bending is so great as to produce a thread of high strength and low extensibility. Specification 279,888 is referred to.

Title: Improvements in or relating to power transmission mechanism in which the drive is interrupted under excessive load
IPC: F27B14/10
Filed: 1937-02-22
Abstract: 490,611. Valves; electric motor control systems. IGRANIC ELECTRIC CO., Ltd. Feb. 22, 1937, No. 5210. Convention date, Feb. 29, 1936. [Class 135] [Also in Group XXXVII] In electrically-operated mechanism for actuating valves &c. adapted to be driven against a stop and including a part such as a worm 5 which, when the valve meets the stop, is adapted to move against a bias and stop the motor, means are provided for locking the part against movement in either direction selectively. The invention is adapted for use with valve-operating mechanism of the kind disclosed in Specification 230,410, [Class 135]. The worm 5 is carried by an axially movable shaft 37 connected with a motor M by a slidable coupling 42. Thrust collars 48, 49 riveted to the outer race of a ball bearing 47 are located between stops 52, 53, the latter being slidable in a rotatable sleeve 54 and pressed by a spring 56. The sleeve 54 is itself slidable inside a flange 58 on the casing. Stop 53 has projections 59, Fig. 6, which extend through slots 60 in sleeve 54 and normally engage the left-hand face of flange 58. The left-hand face of a flange 61 on sleeve 54 normally engages a ring 57 screwed in the casing while the right-hand face has recesses 62 in alignment with the projections 59. These projections and flange 61 also co-operate with stops 63 on the casing. A screw 64 is used to lock sleeve 54 in one of two angular positions corresponding to the selective locking of the worm 5. In one position recesses 62 and stops 59 are aligned with stops 63; the stops 59 are then located between flange 58 and stops 63. Stop 53 is thus completely looked and since recesses 62 and stops 63 are aligned sleeve 54 is movable to'the right. The worm is thus locked against movement to the left but may move to the right against the spring 56. With sleeve 54 locked in the other position, stops 59 on member 53 and recesses 62 in flange 61 are out of alignment with stops 63. Sleeve 54 is then locked by ring 57 against axial movement to the left, and to the right by stops 63. The worm is thus locked against movement to the right by engagement of collar 49 with stop 52, but may move to the left with the stop 53. The torque limit switch is controlled by the movements of the collars 48, 49 which engage a pin on a rocker arm carrying the contacts.

[Also in Group XXIX] A tool operable by fluid pressure for crimping electrical connectors on to electrical conductors comprises one crimping die which is movable relative to another, a chamber in which a high fluid pressure is arranged to be suddenly generated and to be stored, and means for transmitting, at a rate which is slow compared with its rate of generation, the pressure from the chamber to operate the movable crimping die of the tool. The tool has a crimping head A and a body B having a chamber 10 defined by two parts 11 and 11<SP>1</SP> clamped together. An hydraulic liquid 12 is confined in the part 11<SP>1</SP> by a resilient diaphragm 13. A second chamber 14 in the body B accommodates a spring-loaded piston for actuating the crimping die 22 and the chamber communicates with the liquid 12 by a conduit 18. An opening 27 on the body seats an explosive cartridge 28 and a firing mechanism 30 which includes a trigger 32. The cartridge discharges against a curved surface 31 which distributes the explosive force evenly in the chamber 10. An insert 50 arranged in the conduit 18 restricts the flow of the fluid 12 and determines the speed of travel of the piston 16 and therefore that of the crimping die. The crimping head A contains a rotary die nest 26 as disclosed in Specification 761,323 and the size of the combustion chamber, the charge of the cartridge 28, the effective diameter of the conduit 18 and the viscosity of the fluid are all chosen for crimping the largest connector in the range.
