Title: Improvements in and relating to electric switches of the gas blast type
IPC: H01H33/42
Filed: 1936-04-24
Abstract: 452,202. Gas-blast switches. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. April 24, 1936, No. 11732. Convention date, April 24, 1935. [Class 38 (v)] Fluid actuation. -In a gas - blast switch having its operating mechanism, gas reservoir, and supply appliances maintained at a potential other than that of the contacts, for example, at earth potential, a single insulating element is provided for the transmission of the driving energy and supply of gas to the contacts. The element is preferably a tube housed within the insulator supporting the fixed contact so as to be protected by that insulator. The insulating tube e is of suitable organic material having an upper cap l carrying the movable contact b and having apertures o to pass the gas to the interruption point. The upper end of e slides in a, preferably metallic, guide - member m carrying the insulator c supporting the fixed nozzle contact a, whereas a lower cap on e slides on a supply pipe k communicating over an electromagnetically-controlled valve h with the reservoir i. A weather-protective ceramic insulator d carrying the guide m is supported on a casing n for the actuating mechanism, which comprises a cylinder g communicating with pipes k, and a lever f connected to the piston and to the tube e to move the latter. Due to the external diameter of k being less than the internal diameter of m, when gas is admitted to e, the pressure tends to force it downwards and preferably the initial movement of e is effected in this way and not by the mechanism f, g. Preferably, the openings o are dimensioned so that when the opening at a is released by the contact b, a reduction of gas-pressure above the cap l is obtained whilst the pressure below is maintained, which results in a reduction of driving power to e or even in braking, so that the movement of b is retarded in the region where blast conditions are most suitable for arc-extinction.

A cutting tube 15 is pushed into a clay seam 4 and then rotated, whereby a wire or bar (22) across its forward cutting edge (Fig. 8, not shown) severs a cylindrical piece, which is discharged rearwards on to conveyer 9 when tube 15 is again pushed into the seam to cut the next piece. Cutting tube 15 is mounted on rotary tube 14, which is rotated within advance tube 13 by one of cylinders 20, which carry the ends of rope 19 turned round tube 14, being retracted, the other cylinder 20 acting as a brake. Cylinders 16 move advance tube 13 longitudinally within guide tube 12. Guide tube 12 is pivoted vertically by cylinder 27, mounted on frame 6, which rotates horizontally on under-frame 5, whereby tube 15 covers a wide range in two planes (Figs. 1, 2, not shown). The apparatus rides on tracks or on wheels 5a on rails 3, and is fixed during cutting by roof-engaging hydraulic props 8, which bear on levers 36 which carry ground-engaging skids 37. Springs 38 lift skids 37 off the ground when props 8 are released. Fig. 6 (not shown) illustrates how frame 6, secured to disc 29, is rotated by reciprocating cylinder 32 and pawl (31), one tooth movement corresponding to one diameter of cutting tube 15. Spring (34) is switched over to the other end of pawl (31) to effect movement the other way. The tube 15 carries tensioning means (Fig. 8) for wire (22) and air holes (Fig. 9, not shown) opening on a widening portion behind the cutting edge. Figs. 10, 11 (not shown) illustrate percussive equipment acting on tube 15 to assist its driving. The bar or wire (22) may be replaced by a wire loop, tightening across tube 15 to sever the clay.

Title: Improvements in the Manufacture of Hard Rubber Jars and the like.
Inventor: WEITLING WILLIAM WANGANSHY
IPC: B29D99/00
Filed: 1916-08-30
Abstract: 103,781. Weitling, W. W. Aug. 30. 1916. Machines for making boxes. Hard-rubber receptacies for use as battery-jars &c. are produced mechanically by folding a sheet f of plastic rubber about a core c and uniting such folded sheet bv pressure to another sheet a placed upon the top of the core. The core c, with the sheet a applied thereto, is placed upon a slide 26 fitted with a presser-plate 28, which is advanced by rack and bevel gearing 40 - - 48 to engage the sheet f, which is supported vertically by adjustable posts 16, and force it between rollers 10, thereby folding the sheet around the core. Continued movement of the slide presses the folded end of the sheet against a back presserplate 51 carried by a slide 49 held by a rod 53 and detent 54, which is then released, the core advancing between the rollers 10 until the plate 51 abuts against an adjustable stop 89. The slide 26 is next withdrawn, and the ends of the sheet folded, in turn, around the end of the core bv lateral movement of the rollers 10. Pressure is then applied to unite the fold and secure the sheet f to the sheet a by advancing the slide 26 with the presser-plate 28, moving inside presser-plates 60, anddepressing a top plate 79. The slide 26 is held in the advanced position by a ratchet and pawl 90, 91, and the plate 28, which is mounted upon bolts 29, is pressed forwards against the action of springs 30 by means of a cam-lever 31. Motion is imparted to the side plates 60 through toggles 62, levers 61, a screwed shaft 68, pinion 70, and treadle-operated rack 71, and to the top plate 79 through a treadle connected to a lever 81 and toggle. 'To prevent contact of the plate 28 with the rubber sheet f during the preliminary advance of the slide 26, this slide carries pistons 33 adapted to engage the core c. The pistons 33 are projected by springs 35 and locked in their projected position by pivoted catches engaging reduced portions of their stems. These catches are released by a spring rod 37 during the final advance of the slide 26, allowing the pistons 33 to be forced back into recesses in the piate 28. The rollers 10 are mounted in slides 6 fitted with racks 19, which engage a pair of yoked sectors controlled by a lever 24. To prevent the rollers from drawing the folded sheet away from the core, each roller is mounted in a frame 8, Fig. 4, pivoted to the slide 6 and is deflected outwards at the end of the lateral folding movement by means of a roller 97 engaging projections 98, 99, the roller being retained in such deflected position by catch members 96 &c. until released by a spring stop 101. A spring 100 restores the roller to its normal position. After pressing, the treadles operating the side and top plates are released, and the slide 26 is withdrawn, drawing back the slide 49 by a chain 56. The core is then removed for vulcanization. The sheets a., f are backed with thin sheet tin b, g to facilitate handling &c.

In Fig. 4, the fluid-permeable helical fin 20 is interwound with an imperforate helical fin 21. A helical channel 25 is formed around the tube 19 by a sleeve 23 and hot gases from a burner (not shown) flow through the channel and through the fin 20 and are exhausted to the chimney 27 via openings 26 in the sleeve 23. Alternatively the outer boundary of the helical channel is formed by a helical strip (18, Fig. 3). In another form in which longitudinally. extending fluid-permeable fins (29, Fig. 5) are attached to the tube (28), these alternate around the tube with impermeable longitudinal elements (32). A burner flame is concentrated on the fluid-permeable fins (29). A heat-pipe system may be incorporated into the fluid permeable fins to increase their thermal conductivity. The fluid-impermeable fins may be either of heat conducting or heat insulating material. In another form described, the heat exchanger may be a tube coiled into a flat coil embedded in a flat, porous plate constituting the fluidpermeable fin. Burners may be positioned on one or both sides of the plate. The fluid-permeable heat-conducting fin may be connected to more than one tube.
