Title: Method of separating air
Inventor: TOOMASU RASUBOON
IPC: F25J3/04
Filed: 1993-06-10
Abstract: PURPOSE: To utilize a large quantity of liquid nitrogen as a circular flow to a low-pressure column by limiting the form speed of liquid air and suppressing the rate of the air entering a high-pressure column in the state of a liquid by using the second section of a temperature-dropped air flow in order to carry out only part of the work which is carried out for forming reboil for the low- pressure column and evaporating impure oxygen. CONSTITUTION: Nitrogen vapor and oxygen-enriched liquid air are obtained by cooling a supplied compressed air flow in a main heat exchanger 4 and dividing the cooled air flow into the vapor and liquid in a high-pressure fractionating column 10. The flow of the latter is withdrawn and divided into a nitrogen fraction and an impure oxygen fraction containing at least 3 vol. impurities in a low-pressure fractionating column 18 and the nitrogen is condensed in condensers-reboilers 24 and 26 and used as a circular flow to each fractionating column 10 and 18. The reboiling in a condenser-reboiler 16 for the low-pressure fractionating column 18 (operated under a pressure of 2-8 bar) is made through the heat exchange with a supplied air flow and gasifies impure oxygen products in the condenser-reboiler 24.  Therefore, a larger quantity of condensed liquid nitrogen can be utilized as a circular flow to the low-pressure column 18.

IPC: A61B18/20
Filed: 1988-06-06
Abstract: PURPOSE:To reduce the diameter of a catheter by mounting a light emissive substance discharge means for discharging a light emissive substance emitting light by laser beam into a lumen through a flash liquid guide hole. CONSTITUTION:A catheter 2 is induced into a predetermined blood vessel and a balloon 6 is inflated to stop blood and the leading end part of the catheter 2 is fixed in the blood vessel by the balloon 6 and a light emissive substance 411 is discharged in a lumen by a light emissive substance supply means 41. A laser apparatus 1 is driven to emit laser beam and the light emissive substance is irradiated with said laser beam to be allowed to emit light to illuminate the interior of the lumen. The interior of the lumen is observed by a monitor television 35 and the fluorescence spectrum obtained through an endoscopic fiber 21 is observed through a spectrum analyzer 33 and, when there is a lesion part, the laser apparatus 1 is driven to destruct the lesion part. As mentioned above, since illumination light is obtained by allowing the light emissive substance discharged in the lumen to emit light by laser beam, an illumination optical fiber becomes unnecessary and the catheter 2 can be made fine.

Abstract: PROBLEM TO BE SOLVED: To improve the health of animals and to reduce the body odors and excrements of the animals by purifying water in a water supply tank by making it permeate a filter layer from the bottom part to the upper part by the water pressure of the water supply tank arranged in the upper part. SOLUTION: When water (city water) to be given to dogs, cats, domestic animals, or the like is charged from the water supply port 31 of a water supply tank 30, the water in the tank 30 flows down downward from a cylindrical body 35, and the water of the cylindrical body 35 flows out from a water passage hole 36 into the lower part 13 of a case body 10. The water stored in the lower part 13 of the case body 10 permeates a cylindrical ceramic layer, a vocanic rock layer, an activated soil layer, and a ceramic ball layer gradually in sequence from the lower part toward the upper part by the pressure of water in the water supply tank 30. The water which permeated from the lower part of a filter layer 20 into the upper part ascends to the upper part of the case body 10, overflows from an opened hole 12, flows on the surface of the case body 10, and is stored in a pan 40.

Abstract: PURPOSE:To simplify a construction, facilitate maintenance and enable a refuse furnace with a hearth to be used even when a fan gets out of order by discharging part of combustion gas by bypassing an induced draft fan and supplying downward the hearth of a furnace without an air preheater with the remainder of the combustion gas together with the fresh air. CONSTITUTION:Part of combustion gas is discharged in a flow rate determined by a damper 5 via a passage 24 and a chimney 15. The remainder is sucked via a passage 22 by an induced draft fan 14 with the air supplied via a damper 6 and an air passage 26 supplied downward a hearth 21 via a passage 23 and dampers 2 and 3. The surplus air and combustion gas are discharged from the chimney 15 via a damper 4 and a passage 25. When the induced draft fan 14 gets out of order, the damper 5 is fully opened, the damper 4 is fully closed and the whole amount of the combustion gas is discharged from the passage 24, the combustion being conducted in a natural draft system. This construction simplifies construction, facilitate maintenance and enables an incinerator to be used also when the fan gets out of order.

Abstract: PURPOSE: To efficiently recover sulfuric acid from waste sulfuric acid contg. org. sludge discharged from a process for synthesizing acrylic ester by holding the waste acid at a temp. at which soluble org. sludge is not deposited and bringing the acid into contact with an adsorbent to allow the sludge to be adsorbed.  
     CONSTITUTION: When waste sulfuric acid contg. org. sludge discharged from a process for synthesizing (meth)acrylic ester from acetone cyanohydrin or (meth) acrylonitrile, sulfuric acid and alcohol is treated to recover sulfuric acid, the waste acid is held at a temp. at which soluble org. sludge is not deposited or a temp. at which deposited soluble org. sludge is dissolved, usually at 60W100°C for ≥ about 4hr to dissolve soluble org. sludge. This waste acid is then brought into contact with an adsorbent such as activated carbon, alumina, molecular sieve or silica gel while keeping the temp. Thus, by allowing the soluble org. sludge to be adsorbed on the adsorbent, sulfuric acid is recovered.

Abstract: PURPOSE:To rapidly execute a fixing process and to eliminate offsetting of a toner even at the time of copying on both faces by using a thermally crosslinkable toner and bringing a heating source into direct contact with the surface of transfer paper on the side to be transferred with a toner image. CONSTITUTION:A fixing roller 31 and a press roller 32 are disposed on both sides of a passage route for the transfer paper in such a manner that the fixing roller 31 and the press roller 32 come into pressurized contact with each other. A cam face of a press cam 34 is brought into pressurized contact with the shaft part of the roller 32 by the energizing force of a spring 35, by which the prescribed pressurizing force is acted on the roller 32. On the other hand, a heater 33 is built in the roller 31 and a thermistor 36 and a temp. fuse 37 provided on the outside of the roller 31 are attached to the heater 33, by which the temp. control is executed. The transfer paper is so fed that the surface thereof to be transferred wit the toner image comes into contact with the roller 31 side. The surface of the transfer paper on the side to be formed with the toner image is thereby brought into direct contact with the heater 33 side. The rapid fixing process is, therefore, executed and the offsetting of the toner is obviated even at the time of copying on both faces.
