Title: Improvements in and relating to devices for the supply, delivery and storage of colloidal cellulose solutions
IPC: D01D1/06
Filed: 1930-06-02
Abstract: <PICT:0356182/IV/1> <PICT:0356182/IV/2> <PICT:0356182/IV/3> For the supply, delivery, and storage of viscose, cuprammonia cellulose, cellulose acetate, and like solutions use is made of endless conduits.  Thus, a series of vats C1 .. C11, Fig. 1, or mixers, presses, or other units is supplied by a conduit A forming a closed circuit and receiving the solution at B, so that, whichever vat is being fed, the solution flows in opposite directions thereto and no dead spaces occur in the conduit.  The supply to each vat &c. is controlled by a "distributer," the body 1, Fig. 4, of which forms a part of the conduit, and has a short flanged branch 3 leading to the vat and controlled by a screw-down valve 5.  After the valve has been closed, the solution below it runs down into the vat, and stagnation of any part of the solution is thus avoided.  Each vat comprises a cylindrical portion and a lower conical portion, communicating with a conical valve 15, Fig. 6, the casing of which is a part of an endless collector conduit 12.  An additional port leads to a drainage member 17, which may serve for emptying the valve body after discharging the vat.  The valve 15 may be operated by a worm 16.

Abstract: 1,017,201. Fuel elements. ENGLISH ELECTRIC CO. Ltd. May 11, 1962 [May 11, 1961], No. 17223/61. Heading G6C. A fuel element comprises a fuel rod fitting closely within a cylindrical can and having at least one groove on its surface, the ends of the or each groove being axially displaced from each other, and the corresponding portion or portions of the can being deformed during manufacture of the fuel element so as to fit closely within the grooves, whereby to prevent relative rotation between the can and the fuel rod. As shown in Fig. 1, the fuel rod 10 has two helical grooves 15, 16 of the same hand formed at its upper and lower ends, respectively, and an intermediate groove 17 of the opposite hand. These grooves engage corresponding projections on the can surface, which are formed by forcing the material of the can 11 into the grooves by hydrostatic pressure after the insertion of the rod into the can, thus preventing both relative rotation and relative axial movement between the rod and the can. Instead of helical grooves, one or more linear grooves extending partially or entirely in the axial direction may be used, or the depressions in the rod surface may consist of a number of small discrete indentations distributed both axially and circumferentially.

Title: Improvements in or relating to electric resistance welding machines
IPC: B23K11/31
Filed: 1954-06-14
Abstract: 780,583. Welding by pressure. IGRANIC ELECTRIC CO., Ltd. June 14, 1954 [June 15, 1953], No. 17403/54. Class 83 (4). In a resistance welding machine having an electrode movable by pressure means, the latter is assisted by a magnetic device comprising a magnet and an armature, one of which is coupled to the electrode. The movable electrode 14 is connected by a stainless steel &c. rod 24 to a double-acting piston and cylinder 20 and the magnet 35 which is fixed to the machine frame above the electrode 14 comprises a U-shaped laminated core 31, Fig. 2, having a bore 31a through which the rod 24 slides, with a winding about each limb 32, 33 of the U so that a magnetic field is produced symmetrically about the rod 24. The winding is formed by a bifurcated member 35a bolted to a bifurcated member 35b, current being supplied from one side of the welding transformer 15 to an extension 35c of member 35a to flow about the limbs 32, 33 to an extension 35d on member 35b which is connected to the electrode 14. The other side of the transformer is connected to the stationary electrode 13. The rectangular armature 37 has a bore through which the rod 24 passes, a roller bearing in the armature engaging a collar on the rod, and rollers 39 on the armature engaging slots in a fork member 43 to guide the armature in vertical movement. The member 43 is adjustably rotatable in a clamp 41 so that the armature can be restricted to vertical movement in any plane, from that parallel with the core 31 in which maximum attraction is obtained to that at right angles to the core 31. A plate 46, Fig. 4, having a part 46b which may be held against a stop 47 by a solenoid-operated latch 48a is adjustably clamped to a collar 45 on the fork 43, so that with the clamp 41 released the fork 43 can be adjusted to allow the armature vertical movement in a selected plane until at some time after the start of current flow the latch is released when the armature will swing into a position of maximum attraction parallel with the core 31. In operation when the armature is to be held in a particular plane throughout welding, the fork 43 is clamped so that the armature is at the desired angle to the core 31, fluid-pressure is applied to the work between the electrodes and is augmented by magnetic force when welding current flows. Alternatively the clamp 41 is released and the plate 46 is clamped to the collar 45 so that the armature is in the desired initial position and the part 46b is held by the latch 48a. The fluid pressure is augmented initially when the current flows by a lower magnetic force but after the current has been flowing for a predetermined time the solenoid latch is disengaged and the armature swings into the position of maximum attraction to exert a larger force on the electrode 14. Springs 61 prevent further movement of the armature. A pin 65 may be inserted in the fork 43 to hold the armature raised so that the electrode 14 is acted on by fluid pressure alone.

Patent GB-440034-A (GB)
Title: Improvements in the saponification of organic esters of cellulose
IPC: D06M11/38
Filed: 1934-06-16
Abstract: Organic esters of cellulose are saponified in two stages, an organic base being used in the first stage, and a mineral agent in the second stage, Preferably, the greater part of the saponification is effected by means of the organic base; for example, cellulose acetate is treated with an aqueous solution of methylamine until the acetyl content corresponds to not more than one acetyl group, and the desired saponification is completed with an aqueous solution of caustic alkali.  The process may be applied to filaments, threads, ribbons, films, and the like in order to obtain an affinity for cotton dyes, a high safe ironing point, high tenacity, and good extensibility and elasticity.  Suitable organic bases are ethylene diamine, methylamine, ethylamine, propylamine, amylamine, triethylamine, trimethylamine, allylamine, tetramethylammonium hydroxide, piperidine, dimethyl ethylene diamine, methyl ethylene diamine, propylene diamine, 1, 2, 3-triaminopropane, and a g -diamino-b -hydroxypropane. Accelerators such as copper and copper salts, as described in Specifications 430,349 and 430,351 may be present.  As mineral saponifying agent, an aqueous or alcoholic solution of caustic alkali, trisodium phosphate, sodium carbonate, or sodium silicate, are specified.  The organic base or the mineral saponifying agent may contain a swelling agent for the cellulose esters.  The materials may be subjected to a stretching operation either before, during, or after saponification.  In an example, cellulose acetate yarn is passed continuously firstly through a bath containing aqueous methylamine and a small amount of copper, and then through a solution of caustic soda.  In a second and similar example, the treatment with the methylamine is carried out under pressure. Specifications 207,562, 323,790, [both in Class 2 (ii)], 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 370,430, 371,461, 378,858, 389,823, 411,094, 417,220, 429,103, 429,447, 430,350, 438,584, 438,585, 438,586, and 435,806 also are referred to.
