Title: Method and apparatus for making sulphuric acid
Inventor: CAMERON GORDON MURRAY
IPC: C01B17/80
Filed: 1986-07-24
Abstract: In a system using the double absorption process for sulphuric acid manufacture, a single acid circulation system and a single cooler are employed. Acid from the exit of the air drying tower and final absorber tower are mixed in a common reservoir, while acid from intermediate absorber tower is discharged to a separate reservoir. Acid from the common reservoir is split between the intermediate and final absorber towers and product line. Acid from the separate reservoir is cooled and split between the drying tower and intermediate absorber tower. The circulation arrangement reduces the cooling to one relatively high temperature location and simplifies acid strength and level control. Only half of the bulk of the circulating acid has to be cooled and the effect of seasonal fluctuating temperatures in the drying tower is minimized.

Title: Measurement of electrical resistivity particulate entrained in a gas stream
Inventor: KRIGMONT HENRY V
IPC: G01N27/07
Filed: 1990-06-05
Abstract: The resistivity of particulate matter in a gas stream, such as a combustion gas stream produced in a coal-fired power plant, is measured by collecting a sample of the particulate on the surface of a porous ceramic cylinder (62), either with or without an applied collection voltage, and then determining the resistance of the sample with a compound measurement electrode (82) having multiple conductors (84,86). The referece electrode (89) and the measurement electrode (82) are spirally wound on the ceramic cylinder (62) in an interdigitated manner, so that the two (82,98) are laterally adjacent down the length of the cylinder (62). The pressure within the cylinder (62) is controllable, with a pressure below atmospheric being applied to draw the particulate to the surface and ascertain when a sufficient sample for measurement is present, and a pressure above atmospheric being applied to blow away the sample after the measurement is completed, thereby preparing the instrument for the taking of another sample.

Filed: 1994-07-29
Abstract: PCT No. PCT/EP94/02526 Sec. 371 Date Jul. 21, 1995 Sec. 102(e) Date Jul. 21, 1995 PCT Filed Jul. 29, 1994 PCT Pub. No. WO95/04003 PCT Pub. Date Feb. 9, 1995The melting tub for producing the molten mass from a mixture of raw material is associated with an additional melting unit by means of which a recycled molten mass is obtained from mineral wool waste largely corresponding to the molten mass obtained from the mixture of raw materials in quality and composition. The recycled molten mass is supplied to the molten mass in the melting tub through a suitable introduction device. The recycling exhaust gas from the additional melting unit is fed to the tub exhaust gas, and the mixture of exhaust gas is utilised for pre-heating combustion air and mixture of raw materials. Due to dividing "preparation of molten mass" into conventional production of molten mass from the mixture of raw materials in the melting tub and concurrent production of molten mass from mineral wool waste in an additional melting unit, molten products and exhaust gas of which are directly supplied to the melting tub, it is possible to utilise mineral wool waste as a recycled starting material in a cost-effective manner without affecting the complicated control of process parameters in conventional production of molten mass.

Title: A method of repairing a reactor coolant pump shaft and a reactor coolant pump repaired by such method
Inventor: VERONESI LUCIANO
IPC: F04D7/08
Filed: 2001-06-06
Granted: 2004-04-07
Abstract: Cracks in the shaft of a reactor coolant pump adjacent a tapered end on which the impeller is mounted are removed by machining a circumferential groove in the pump shaft to a depth and an axial length which removes the cracks but does not extend into the tapered end of the pump shaft. A split ring fills the groove to an outer diameter which matches the outer diameter of the pump shaft. A thermal sleeve shrink fit over the split ring has internal annular ribs engaging the shaft and the ring to form an annulus which communicates with the pump chamber sufficiently to maintain a layer of substantially stagnant coolant over the split ring and the pump shaft at the pressure of the coolant being pumped. An oversized washer between the impeller and the impeller retainer nut overlaps the interface between the impeller and the tapered end of the pump shaft to impede the flow of hot reactor coolant along the keyways in the tapered end of the shaft and the impeller to minimize temperature fluctuations in the vicinity of the thermal sleeve. Preferably, the thermal sleeve has a lower coefficient of thermal expansion than those of the shaft and the split ring.
