Patent GB-106760-A (GB)
IPC: F27D11/04
Abstract: 106,760. Moffat, J. W. Oct. 11, 1916. Electrode furnaces. - An unobstructed reducing- chamber 1 and an electrically - heated crucible 2 below it are rigidly connected so as to tilt together about trunnions 5 for tapping, while a stack 17 with which the chamber normally communicates remains stationary. O r e and flux, fed in through a central hole 25 in the roof of the reduction chamber fall in a shower through the chamber, carbonaceous material being introduced through side holes 23. Gases, burnt by air entering through holes 22 near the top of the chamber, escape by holes 10, 11 near the edge of the roof, so as not to disturb the stream of ore, which may, however, be caused to eddy by appropriately directing the entering air. Holes in a curved plate 13 just above the roof normally register with the holes in the roof and open into flues 15 leading to the chamber 16. The plate 13 may be sufficiently large to close the holes in the roof when the furnace is tilted. Four of the flues may pass through the floor of this chamber and two through a side wall, to reduce the size of the chamber required. A funnel 20, raised bv a lever 21 or otherwise when the furnace is to be tilted, directs the ore into the feed-hole 25 from a preheater 18, connecting the chamber 16 and stack 17. The preheater, which may be of the rotary-tube type, is charged by a hopper 19. A cover 12 for the crucible is preferably similar in size and construction to the roof of the reduction chamber, to allow of standardization of bricks. Six electrodes 3 may be provided. Large and small spouts, for slag and metal respectively, are arranged at opposite sides of the crucible, which is provided with two toothed sections 7 meshing with worms on connected shafts. Specification 3715/10 is referred to.

Title: Improvements relating to washer boxes for coal and the like
IPC: B03B5/24
Filed: 1927-04-26
Abstract: 289,633. Norton, B. April 26, 1927. Valves controlled by pilot or relay valves.- In a coal-washing jig of the kind in which water is caused to pulsate through perforated plating by means of compressed air, the supply of air is automatically regulated in accordance with the supply of coal to the washer box. A relief valve in the air supply pipe is opened when a pivoted flap in the coal shoot falls. The top side of a diaphragm 36 on the spindle of the relief valve 39 is connected to the compressed air supply and the under side is connected with the atmosphere through a pipe 44 and ports 41 when the flap (not shown) is in its raised position. The flap, in falling, raises the pilot valve 40, which closes the ports 41, and connects the under side of the diaphragm to air pressure through pipes 33, 35, and 44. The valve 39 opens as the pressure on each side of the diaphragm equalizes. A delayed action device comprising a bye-pass 51, throttle valve 52, and check valve 53 allows the pressure beneath the diaphragm to rise slowly and fall quickly. In a further modification the lower side of the diaphragm is always connected to atmosphere, and the upper side, which is normally under pressure, is connected to atmosphere when the flap falls.

Abstract: 878,712. Determining relative quantities of fluid mixture constituents. GENERAL MOTORS CORPORATION. March 30, 1960 [April 9, 1959], No. 11204/60. Class 37. The vapour content of a liquid, under static or dynamic conditions, is determined by the use of a capacitor between the plates of which is situated a test chamber for the liquid, the measurement being independent of the distribution of the vapour by arranging the electric field to be uniform throughout the test chamber. The capacitor forms one arm of a bridge which also includes a reference chamber and capacitor in another arm. For testing a gear pump by measuring the proportion of vapour produced in a fuel by cavitation near the inlet of the pump, Fig. 1 (not shown), fuel is pumped by the latter through conduit 42, Figs. 2 and 3, and, for reference and temperature compensation, by a lower pressure pump through conduit 48. Conductive plates 44, 46, 50 and 52 mounted on opposite sides of the conduits are electrically screened by housing 28, which may be of aluminium and filled with nitrogen at greater than atmospheric pressure. A difference in capacitance of conduits 42 and 48 is detected by the circuit of Fig. 5, the components of which are preferably housed within a sealed cover 56 and connected to the conductive plates through sealed connector 54. The conductive plates are preferably produced by painting or spraying metal on the conduit material. The latter may be of fibre glass, polystyrene, or, preferably, of glass fibre-filled diallyl phthalate moulding compound, and the meter 66 may be calibrated to read in terms of percentage of vapour.
