Abstract: 348,413. Coal-cutting machines; ratchet gearing. ANDERSON, BOYES, & CO., Ltd., and ANDERSON, A., Flemington Electric Works, Motherwell, Lanarkshire. May 30, 1930, No. 16708. [Class 68 (i).] In a coal-cutting machine with rope haulage wherein a haulage drum is driven through ratchet gearing and a detent normally prevents reverse movement of the ratchet wheel, the detent 7 is loosely mounted on a pin 6 with polygonal ends slidably engaging guides 13, the pin 6 being connected by a toggle 2, 3, to an operating handle 17, whereby, on bending the toggle, the detent is moved clear of the teeth of the ratchet wheel 8. Preferably a cam 10 is provided on the detent to co-operate with a striker 11 to rock the detent during its movement. An arm 14 is rigidly mounted on the pin 6 and forms an anchorage for a spring 15 which urges the detent towards the ratchet wheel. A spring-urged plunger engages the pivot 4 of the toggle with the parts in the position shown, so as to prevent accidental bending of the toggle.

Title: Fluid pressure balancing devices
IPC: G05D16/06
Filed: 1974-04-03
Abstract: 1471411 Valves BARKING BRASSWARE CO Ltd 3 April 1974 [6 April 1973] 16728/73 Heading F2V A fluid pressure balancing device comprises a flexible diaphragm 14 forming two divided chambers 12, a member 18 carried by the diaphragm and forming two seats 20, and two valve closure members 22. In operation, cold water passes from a first inlet 28 into a first outlet 30, and hot water passes from a second inlet 28 to a second outlet 30. If there is a temporary reduction in cold water pressure the diaphragm moves towards the cold water path and reduces the resistance to flow through the cold water path, and simultaneously increases the resistance to flow through the hot water path and therefore the device maintains a substantially constant temperature of mixed water flowing to a shower. Should the flow of cold water cease, the diaphragm seats the valve on the hot water path and shuts off this supply.

Abstract: 1,131,038. Ornamenting. TEFAL. 15 April, 1966 [15 April, 1965], No. 16730/66. Heading B6G. [Also in Division G5] A process for producing a pattern in a matrix, comprises producing a homogeneous mixture of magnetic metallic particles in a dispersion of polytetrafluoroethylene, causing said particles to arrange themselves in a desired pattern by submitting the mixture, while in a plastic state, to a magnetic field of force having the required pattern, and causing the polytetrafluoroethylene dispersion to solidify, by heat treatment, while the particles retain their desired pattern, whereby said particles are fixed in that pattern within a matrix of solid polytetrafluoroethylene. Either a permanent magnet or an electromagnet is used to provide the magnetic field and one or both of the polepieces are shaped to give the desired pattern of magnetic particles; star-shaped and ring-shaped patterns are referred to. The mixture can contain coloured fluorescent or phosphorescent particles. Decorated articles such as containers or signs can be produced by the method.

Abstract: 632,398. Making fusion welding electrodes. NATIONAL CYLINDER GAS CO. June 27, 1947, No. 17013. Convention date, July 30, 1946. [Classes 83 (ii) and 83 (iv)] Uniting by fusion; drawing; rolling; altering physical structure.-An electrode for arc or gas welding is made from non-magnetic austenitic, stainless steel or the like rod by cold working in stages to reduce its area to at most 25 per cent until it becomes responsive to magnetism, the working temperatures being kept below the critical or recalescent point to prevent nullification of the magnetizing effect of the working. In welding, a tubular arc 31 is produced with a smooth weld 37 and no splashing due to the denser magnetic skin 26 which is produced by cold-drawing or coldrolling the upper part of a rimming steel ingot. The rim should be from 35 to 60 per cent, preferably 50 per cent, and the segregates are found only in the core 28 of the electrode. A hot rolled rod is reduced to half diameter in 5 or more cold stages, not greater than 15 per cent each, without intermediate annealing, and is tested with a magnet for ferro-magnetic properties. In modifications, Figs. 6, 7, and 8, not shown, the denser cold worked skin may be a helical strip wound on the core, or a longitudinal jointed strip folded about the core by drawing, or a core may be inserted in a tube and the whole drawn down. The core and skin may have different compositions, e.g. 25 per cent chrome, 12 per cent nickel core, with a mild steel sheath to produce a desired alloy in the weld.

The tubes 37 are slidable in arms 38 which are linked by a rotatable shaft 39, In operation, one of the tubes 37 is pressed against a die ring 36 by a piston and cylinder unit 45 the force of which overcomes the bias of a spring 53. A billet 17 is extruded through the die 33 and die ring 36 by pressurizing a mixture of glycerol and ethylene glycol within the chambers 8, 9, the extrudate, e.g. wire, rod or pipe being received within the tube 37. A back pressure may be applied to the extruded article by filling the tube 37 with fluid from a source 51. After extrusion, the shaft 39 is rotated so as to bring the other tube 37 into alignment with the die 33 and the tube 37 containing the extruded article into alignment with a piston-rod 58 to enable it to be extracted. A billet 17 is loaded into the chamber 8 by allowing the foremost of a stack of billets 17 on a rack 18 to roll on to rollers 22 from which it is pushed into the chamber 8 by the plug 28. The latter is retained in the chamber 8 to close its one end by lowering a plate 25 by a cylinder 26.

[Class 103 (i)] A fluid-pressure brake system comprises a main reservoir 1, inside which is an auxiliary reservoir 3 and a valve adapted to connect the reservoirs when the pressure or suction in the auxiliary reservoir exceeds a predetermined limit. Air from a compressor is supplied to a chamber 11, past a check valve 18, by a passage 21 to the auxiliary reservoir from which air is supplied by passage 40, past a valve 34, when open, and a passage 35 to the main reservoir. The auxiliary reservoir is thus quickly charged to give a ready supply for braking. When main reservoir pressure attains a certain value it acts through a port 17 in a bellows 13 to open a valve 12 and byepass the pressure air from the compressor to atmospheric passage 8.
