Title: Production of exothermic type gas
Inventor: KANEFUJI KOUICHIROU
IPC: B01J19/14
Filed: 1981-06-17
Abstract: PURPOSE:To prevent the deposition of carbon through quick cooling of a high temp. combustion gas by passing the gas produced by imperfect combustion of fuel in a combustion chamber through a partition consisting of an air permeable solid prior to cooling of the same with a cooler. CONSTITUTION:A gaseous mixture of gaseous fuel and air mixed at an air ratio smaller than the air ratio of perfect combustion in a fuel mixing device is supplied through a piping 3 to a burner 2, and is imperfectly burned in a combustion chamber 4. The resultant combustion gas flows from the chamber 4 into a cooling chamber 5 by passing through an air permeable solid 6 and at this time, it is heated to a high temp. by convectional heat transfer because the solid 6 has large surface areas, so that the gas is cooled quickly. This gas flows into the chamber 5. Therefore, Boudouard's reaction occurs hardly, and the deposition of carbon (soot) is prevented. The combustion gas in the chamber 5 is further cooled by other cooler. It is equally well to provide the solid 6 to the outlet part of a primary cooling chamber after the chamber 4, and this solid consists of a net-like or fibrous heat resistant material such as metals or ceramics.

Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To reduce the sliding resistance, and to improve the sealing property by combining a tape of expanded graphite and a fiber to be impregnated with the lubricant, and covering the periphery thereof with a reinforcing fiber. SOLUTION: A tape 1 of expanded graphite and a carbon fiber 2 as a fiber to be impregnated with lubricant are overlapped with each other, and the periphery thereof is covered with a bag of stainless steel 3 so as to obtain a knitting yarn 4 for gland packing. Since the tape 1 of expanded graphite and the fiber 2 to be impregnated with lubricant are combined and the periphery thereof is covered with the reinforcing fiber 3, rebound elasticity is generated in the packing, and furthermore, lubricant holding property is improved. Quantity of the fiber to be impregnated with lubricant is desirably set at 20 wt.% in relation to the cross sectional area of a sheet of expanded graphite.  Furthermore, a range at 60 wt.%-120 wt.% is most desirable, and balance between the sealing property, sliding resistance and shape holding property of the packing at a rate in this range is especially excellent.

Abstract: PURPOSE:To improve energy consumption and habitability by transmitting cool air from an evaporator into a compartment by means of brine in the above-captioned air conditioning device having a compression type refrigeration cycle and reserving the cool air in a refrigeration condenser provided on the way of a brine pipe. CONSTITUTION:When a compartment is sufficiently cooled in an air-conditioned running, selector valves 43 and 41 for bypass are switched to supply brine 2 to a bypass flow line 42 and a refrigeration condenser 5 for reserving cool air. On the other hand, when cooling of the compartment becomes insufficient, a selector valve 43 is switched to supply brine 2 to a heat exchanger 3 in the compartment for cooling. At this time, if the cool air is sufficiently reserved in the refrigeration condenser 5, the cool air in the brine 2 is not utilized for reserving, but the whole is utilized for cooling. Further, the cool air previously reserved in the refrigeration condenser 5 is took out for utilization of cooling. With this constitution, energy economy may be improved and cooling of the compartment may be stabilized thereby to improve habitability.
