摘要： 730,812. Cables. CABLES & PLASTICS, Ltd., and PILLING, H. S. Dec. 29, 1953 [Dec. 31, 1952], No. 33087/53. Class 36. A cable comprises at least one conductor which is covered with an insulating material such as polythene, then with a polyvinyl chloride sheath adhering firmly to the insulation and then with a nylon sheath adhering firmly to the polyvinyl chloride sheath. Several individually insulated conductors may be laid up together to form a core over which the polyvinyl chloride and nylon sheaths are applied. The insulation and sheaths may be applied by extrusion, a vacuum being formed in the head of the extrusion apparatus to ensure that the various layers fit tightly on to the underlying surfaces.

摘要： 23,576. Circulators, Ltd., Schofield, H., and Sedgwick, C. H. Oct. 25. Partitions in water space.-Relates to jackets provided with tapering hoods placed over furnace-flues for promoting the water-circulation. To allow a jacket to be fitted and adjusted upon flues of different diameters, the end walls supporting the jacket are made flexible, and the jacket itself is made up of overlapping curved plates. The hood may be formed of two parts which overlap longitudinally. The end walls of the jacket shown consist of short thin plates a forming links connected by hinge-pins b. The walls are supported vertically upon the flue by flanges c on the plates, and are secured by chains j and adjusting-screws k . The plates e forming the jacket are secured by inserting projections d on the end walls in slots in the plates, and by driving wedges through the slotted ends of the projections. The two parts of the hood g are connected to the end walls by brackets h and bolts h . A hood may be provided with one or more apertures in its upper part for the escape of steam, a cover-plate being placed above and parallel to the hood. Curved or straight directing-pieces m may be placed inside the jacket or hood.

摘要： ,14,011. Circulators, Ltd., Ross, S. J., and Schofield, H. June 15. Partitions in water space.-A saddle-shaped partition placed around the flue of a Cornish or like boiler for promoting the water-circulation is formed in sections which may be readily fitted and removed. The partition shown consists of a number of curved plates e, which are held in position between frames b secured to the flue. The plates slide in grooves d formed in the frames. The ends of the plates may be provided with notches adapted to interlock with corresponding notches in the frames. The discharge nozzle f may be secured by means of side-flanges which slide in grooves formed in bars h at the top of the frames. The flanges of the boiler flue may be used to form the frames.

摘要： 524,887. Sliver guides. SCHOFIELD, J., SCHOFIELD, H., and HALL, J. Feb. 10, 1939, No. 4374. [Class 120 (i)] A sliver condensing funnel or guide for use in drawing and similar frames is in two parts, the lower part being formed of, two independent semi-conical portions A 1 , A 2 which together form a hollow bifurcated cone with the apex opening a at the bottom and which is held to the upper part C by an outer truncated conical sleeve B having an internal screwed portion b engaging external threads on the part C and having the inclination or taper of its inner surface slightly less steep than that of the exterior of the portions A 1 , A 2 so that the portions A 1 A 2 can fulcrum to a limited extent about the lower edge of the sleeve to allow the opening a to expand for the passage of an obstruction in the sliver without breaking it.

摘要： 22,981. Circulators, Ltd., and Schofield, H. Oct. 11. Partitions and baffles in water space.-In a locomotive, marine, or like boiler having vertical circulation-spaces, bent plates having their upper parts extended considerably in an horizontal direction are placed at the top of the spaces to throw a current of water over the crown of the furnace or combustion chamber. In the locomotive boiler shown, bent plates a , a arranged back to back are placed at the top of the circulation space formed by a false tube-plate E. The distance between the horizontal portion of the plate a and the top of the fire-box is less than the distance between the vertical portion of the plate and the tubeplate. A bent plate similar to the plate a is arranged at the top of the space behind the combustion chamber of a marine boiler.

摘要： 8479. Circulators, Ltd., Ross, S. J., and Schofield, H. April 8. Partitions in water space.-Relates to the promotion of the circulation in steam boilers in the manner set forth in Specification 2348/05, and consists mainly in constructing the guiding- plates which promote the circulation so that they can be readily removed for inspection or repairs, and further in the utilization of the spaces between the combustion - chambers of marine boilers for promoting circulation. As applied to a double - ended boiler, the curved deflector which is arranged above each tubeplate is built of fixed sections a and detachable sections e arranged alternately. Each fixed section comprises a curved front plate a, Figs. 3 and 4, connected through a spacing-plate a to an angle-bracket a , which is bolted to a boiler stay b. The fixed sections thus provide curved guides in which the detachable sections slide, and their lower edges are bent up to serve as supports. A space d is left between the deflector and the adjacent edge e of the combustion-chamber in order that the water circulation may prevent the accumulation of a deposit on the chamber crown. The vertical side-plates f of the circulation passages are made readily removable either by providing keyhole slots for their fastening bolts or screws, or by providing them with hooks which clip over the smoke-tubes. The fastening-bolts may be carried by brackets clamped to the smoketubes. The spaces between the combustion chambers are provided with detachable sideplates i hooked on the stay-bolts e , bell mouthed inlet guides i , removable baffles i in front of the inlets, and curved deflectors j at the top. The application of the invention to a wet-back marine boiler is also described.

摘要： 8480. Circulators, Ltd., Ross, S. J., and Schofield, H. April 8. Water-circulation, apparatus for promoting; partitions in water space.-Relates to a particular form and arrangement of a device for promoting longitudinal circulation of the water in internally-fired boilers with or without crosstubes. The device comprises a cap a mounted saddle-wise on the furnace or furnace-flue B, and provided with inlet openings b and a contracted discharge opening c. The inlet openings may be provided with inwardlydirected flanges b', which prevent steam formed within the cap from reversing the water flow through the inlet openings. The cap is held in place by girth straps a secured to lugs a . In a modification, the cap is arranged over the mouth of a vertical Galloway tube, and is held in position by a tie-rod passing through the tube and hooked to a cross-bar at the lower end. Convergent pairs of baffles are provided within this type of cap to direct the water flow towards the centre of the discharge outlet, and the inlet openings b may be made much smaller or dispensed with.

摘要： A roller suitable for use in printing machines, leather tanning machines, duplicating machinery, typewriters, textile machines, &c. is made by coating a central stock or core with adhesive (after degreasing if necessary), placing the core in an enclosed mould, evacuating air from the mould, admitting a fluid mixture of polyvinyl chloride and plasticiser, e.g. di-octyl phthalate, and heating the whole in an oven to convert the fluid mixture to an elastic solid forming the outer surface of the roller. The adhesive may be the composition described in Specification 569,666, and may be applied in two stages, first as a primer immediately after degreasing and then, immediately before use, as a main coating. The oven may have a temperature differential within its heating space of less than 2 DEG C., and is gradually heated to about 160 DEG C. The roller surface is machined and ground. The stock or core may be of metal or wood.
