Title: Improvements relating to oxygen cutting machines
IPC: B23K7/00
Filed: 1926-11-26
Abstract: 284,810. Hancock, L. J. Nov. 26, 1926. Dividing by fusion.-A flame cutting machine of the kind in which the blowpipe is mounted on a compound slide and is moved in conformity with a pattern, templet &c. comprises a carriage slidable on rails arranged one on each side of the upper face of the templet-carrying table and provided itself with transverse rails on which slide the carriage bearing the blowpipe, driving motor and tracer wheel or rollers. The blowpipe carriage may be provided with an arm extending over a side table and provided with one or more blowpipes. A table a, on which may be mounted a drawing or a strip template 15 secured in slotted studs 16 as described in Specification 243,816, is provided with rails 1 on which a wheeled carriage 2 may be traversed. This carriage has rails 6 on which may be traversed a carriage 4 carrying a motor 13 which drives a hand-guided tracer wheel running over a drawing or rollers 14 engaging the template 15, and also a blowpipe arm 7. The motor casing is mounted so as to turn freely in bearings 13<1> on a vertical axis, and the blowpipe arm is secured in adjusted position in the carriage by screws 8 and is provided with a hand-operated pinion 11 engaging a rack on the blowpipe 9 for vertical adjustment. The blowpipe mav be mounted and controlled as described in Specification 249,976 so as to make bevelled cuts. For cutting discs a radius bar centred in the table may be fixed to the tracer spindle. In order to make straight longitudinal or transverse cuts, two cross arms 21, 22, Fig. 3, at an angle of 90‹ with each other are carried, preferably detachably, by the motor casing, one arm being in line with the direction of travel of the tracer wheel. By rotating the casing these arms are arranged to engage respectively spring-pressed plungers 25, 26 mounted on the carriage 4 for locking either the carriage 2 or 4 respectively. The plunger 26 on being pushed down by the arm 22 operates rods 31 through the toggle 30 to lock the wheels 5, and the plunger 25, which is slidable over a frame 27 pivoted at 28 to the carriage 2, on being pushed down by the arm 21 operates detents 29 on the frame to lock the wheels 3. The arms are provided with inclined operating surfaces 23, 24, Fig. 4, provided with recesses 35, to lock the plungers in position. When using a manually guided tracer wheel, the motor 13 and tracer wheel 32. Fig. 4, may be mounted in a bracket 36 at the side of the carriage 4. In this case the arm 22 operates the plunger 25 and the arm 21 the plunger 26. The tracer wheel is guided by a handle 37 and is pressed down by a spring 38. The motor wheel &c. may be lifted relatively to the carriage 4 by increasing the height of the table a in order to render the arms inoperative.

Title: Improvements in or relating to moulded plastic articles and processes of making same
Inventor: COLER MYRON ABRAHAM
IPC: C08K9/04
Filed: 1953-10-31
Abstract: An anti-static moulded plastic composition comprises a thermoplastic synthetic resin, e.g. polymers and copolymers of methyl methacrylate, vinyl and vinylidene chlorides, ethylene and styrene, 3 to 37 per cent of a finely-divided insoluble sorptive material stable under moulding conditions, and 0.5 to 40 per cent, preferably 5 to 23 per cent, by weight of a liquid organic destaticizing agent having a low vapour pressure and a dielectric constant greater than 25.  The sorptive material may be silica gel, wood flour, a -cellulose, a pigment or a thermosetting plastic, or a plastic having a softening-point higher than the synthetic resin, e.g. polyvinyl chloride, and wetting agents such as the sodium salt of sulphated long-chain fatty alcohols or sodium naphthenate may be included.  The destaticizing agent is conductive or rendered conductive by the ionization of a dissolved electrolyte, e.g. polyhydric alcohols including higher molecular weight polyethylene glycols, and N-acetylethanolamine or amides, e.g. formamide, nitriles and nitro-compounds and aqueous solutions may contain an ionizable salt and a hydrotropic agent such as sodium xylene sulphonate and toluene sulphonic acid.  Lubricants, plasticisers, dyes, pigments and fillers may also be present.  The composition may be prepared by mixing the finely-divided ingredients, added separately, or with the sorptive material pretreated with organic liquid destaticizing agent, at a temperature below the softening-point of the plastic material, or as a powder, and applying sufficient heat and pressure to mould the material.  The materials may also be incorporated in the monomer or during the polymerization, for example at the liquid stage, after which the polymerization is completed.

Title: Improvements in or relating to gyratory crushers and like crushing machines
IPC: B02C2/04
Filed: 1963-07-30
Abstract: 966,185. Gyratory crushers. H. G. BOULY. (Nordberg Manufacturing Co.). July 30, 1963, No. 30217/63. Heading B2A. A gyratory crusher comprises a crushing bowl 22 mounted for rotary adjustment relative to the main frame 10 of the crusher, a locking-arrangement 55 to hold the bowl against rotary movement and a fluid-operated ram 44 to release the locking hold on the bowl and rotate it. As described, rams 44 each comprise a cylinder 46 having an operating-head 47 which contacts a stationary, toothed, driving- ring 48 on the exterior of the cap 30 which is locked to the bowl 22, so that both can rotate together. The lock 55 which secures the ring 48 and the bowl to the frame 10 comprises a pivotal arm 56, extending towards the corresponding ram 44, mounted on a post 58 and encircled by a coil-spring which biases the arm towards the bowl and ring; the arm includes a cam-face 62 facing the ram 44. As soon as the ram is operated to rotate the ring 48 its front surface contacts the cam-face 62 and rotates the arm out of contact with the ring so that it is made free to rotate. When the rams are "at rest", the leading edge of each web 50 is spaced away from the next tooth 52 on the ring, while the upper and lower flat surfaces 54 are in contact with the cam face 62, so that during initial movement of the ram the web 50 slides along the ring 48 until it contacts the tooth 52, but at the same time the flat surfaces 54 contact the face 62 to move the lock out of engagement. Thus thrust is not applied to the bowl until it is unlocked.

Title: Improvements in or relating to the installation of oil-filled electric cables
Inventor: ARKELL CHARLES ANTHONY
IPC: H01B9/06
Filed: 1959-09-04
Abstract: 886,643. Terminating cables. BRITISH INSULATED CALLENDER'S CABLES Ltd. Sept. 5, 1960 [Sept. 4, 1959], No. 30282/59. Class 36. In a method for making an oil-filled cable installation the lower end of the cable forms the upper end of the shorter limb of a U-tube and, after sealing the upper end of the cable against entry of air, oil is allowed to flow out through the upper end of the shorter limb until the pressure at this point is sufficiently reduced to enable jointing or termination to take place. After evacuating the jointing or termination, oil is introduced to refill the cable and fill the applied jointing or termination. In a modification, firstly, part of the cable is run out and oil is allowed to drain from the shorter limb of the U-tube. This may be repeated several times before the jointing or termination operation as outlined above. A vacuum is maintained in the upper part of the longer limb until after the jointing or termination by attaching a vacuum pump to this end before allowing any oil to drain out from the lower end of the cable.

Patent GB-652844-A (GB)
Title: Improvements in and relating to the production of artificial threads, fibres, filaments, staple fibres and the like
IPC: C07C51/487
Filed: 1948-11-24
Abstract: Artificial filaments, fibres, threads and the like are obtained by extruding a solution of cellulose acetate into an aqueous coagulating bath containing potassium acetate in a concentration of from 20 per cent up to saturation point.  The bath preferably also contains free acetic acid, e.g. in a proportion of 50-250 grams per litre.  The spinning solution may be heated to a temperature higher than that of the coagulating bath, e.g. the solution may be at 40-55 DEG  C. and the coagulating bath may be maintained at 15-45 DEG  C.  The spinning solution may be obtained by dissolving cellulose acetate in acetone or acetic acid or it may be a solution of cellulose acetate in aqueous acetic acid obtained by acetylating cellulose in presence of acetic acid, adding water for ripening the cellulose acetate in solution, and neutralizing the acid catalyst.  The cellulose acetate may be present in the solution in a proportion of 9-15 per cent.  The solution may be clear or pigmented.  If a solution of cellulose acetate in aqueous acetic acid is used, the concentration of acetic acid in the coagulating bath may be prevented from increasing, by continuously removing some of the liquid, recovering acetic acid from the withdrawn liquid, and feeding p  potassium acetate solution containing a lower concentration of acetic acid into the bath. Threads having filament deniers as low as 1.5 may be obtained with tenacities of at least 1.1 grams per denier and dry extensibilities of 25-40 per cent.  The threads obtained are resistant to direct cotton dyes and to acid wool dyes.  In an example, cotton linters, pretreated with a solution of sulphuric acid in acetic acid, are acetylated with a mixture of acetic anhydride, acetic acid, and sulphuric acid, the reaction temperature being kept below 40 DEG  C. After the acetylation, water is added and the solution is ripened at 26 DEG  C.  The catalyst is then neutralized by adding sodium acetate in aqueous acetic acid. The solution is filtered, de-aerated, and then extruded into an aqueous solution of potassium acetate and acetic acid.  The filaments obtained are taken up by a godet and stretched while passing to a second godet.  The spinning solution may contain a pigment such as titanium dioxide.  In another example, cellulose acetate solution is extruded through a jet having 3000 orifices and the filaments produced are withdrawn from the bath as a tow of parallel filaments.  The tow is washed and then stretched in boiling water.  Specifications 7341/03, [Class 2], 3973/11, 13872/14, 15544/14, 177,868, 179,234, 198,392, 211,889, 230,813, 312,671, 334,838, [all in Class 2 (ii)], 341,148, 343,062, 434,425, 509,702 and 652,845 are referred to.
