Filed: 1975-01-24
Abstract: 1490654 Cooling systems for shaft furnaces DEMAG AG 24 Jan 1975 [26 Jan 1974] 3168/75 Heading F4B A cooling system for a furnace, particularly a blast furnace, is arranged in two sections, both sections being normally supplied with water by a pump, but in an emergency, one section being supplied by an emergency pumped supply and the other section being supplied by gravity from a raised water tank. The tuyere arch coolers 4<SP>1</SP> and the cooling boxes 5 of a blast furnace are connected to a pump 1 by a line 3 having a valve 22 and a return line 8 with a valve 23. The tuyeres 6 and the hot blast valves 7 are connected to the pump by a line 4, and the outlet lines from the two sets of cooled parts are joined and feed hot water to a cooler 11 and back to the pump 1. An elevated water tank 14 is connected to the pump outlet, and to the supply to tuyere arches and cooling boxes on the furnace side of the valve 22. A valved line 19 leads from the outlet from the tuyeres arches and cooling boxes to a collection tank 15. In the event of a failure of the pump 1, a normally closed valve 21 in the line 19 opens so that both sets of parts are cooled by water from the tank 14 until the emergency supply or emergency pump 13 comes into operation. The valves 22, 23 close when the emergency supply starts, thus cutting off the tuyere arches and cooling boxes 4<SP>1</SP>, 5 from the pump, so that these parts are cooled solely by the flow of water by gravity from tank 14 to collector tank 15, and the remaining parts are cooled by water circulated by the emergency pump through the cooler 11. When the emergency is over, valve 21 closes and valve 22 and 23 close, and water from the collector tank 15 is pumped back to tank 14.

Abstract: 797,560. Lubricating. ESSO RESEARCH & ENGINEERING CO. Oct. 16, 1956 [Feb. 7, 1956], No. 3838/56. Class 12 (3). A method of preventing bearing surfaces from deterioration comprises admitting a lubricating oil to the bearing surfaces and blanketing the admitted lubricant with a gas which is inert to the lubricating oil, e.g. steam, carbon dioxide, vaporized methyl iodide or bromide, nitrogen or carbon tetrachloride. Oil is fed from a sump A through a feed line B to an atomizer C and thence to the bearing of an aircraft turbine. Inert gas is fed into the atomizer at D and hence the lubricant is emitted mixed with and surrounded by a non-inflammable gas envelope. Air will be excluded from the bearing arc and the incorporation of a shroud E between the bearing and the turbine disc would practically eliminate an oxidizing atmosphere altogether.
