Title: Storage material for sulfur oxide, its production and its use
Inventor: STREHLAU WOLFGANG DR
IPC: B01D53/94
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To make a storage material sufficiently satisfy high storage ability and a request for a starting temp. of desulfurization by dispersing magnesium oxide in the storage material in such a form that the magnesium oxide is present in a stoichiometrically excess amt., the molar ratio of the magnesium oxide to aluminum oxide is more than a prescribed value and the magnesium oxide is highly homogeneously dispersed in the material. SOLUTION: This storage material disperses magnesium oxide which is present in a stoichiometrically excess amt., uniformly in Mg/Al-spinel and stabilizes its specific surface area even when the material is used at a high temp. In this purpose, the molar ratio of the magnesium oxide to aluminum oxide is required to be at least 1.1:1. Then, sulfur oxides are stored in the form of magnesium sulfate by the reaction with the substantially excess amt. of the magnesium oxide. Or, the storage material has good resistance against ageing, which is advantageously attributed to the reaction of the sulfur oxides with the highly dispersed magnesium oxide. Thereby, the supporting structure having the high surface area of the material can be protected from a fracture due to the reaction of a waste gas with the sulfur oxides.

IPC: F28F9/02
Filed: 1984-04-24
Abstract: PURPOSE:To reduce the surface tension of heat rransfer medium or drain and consequently allow the heat transfer medium or drain to flow out to a header without staying in the interior of heat transfer pipes by a structure wherein the heat transfer pipes, at the tip of each of which notches are provided, are protrudedly inserted in the interior of the header and joined. CONSTITUTION:Heat transfer pipes 2 providing with a plurality of notches 4 cut so as to make an acute angle at each tip, are protrudedly inserted in the interior of a lower header 1b and, after that, the upper part 5 of the notches is welded. When water or steam drain 3 is discharged by gravity, the water or steam drain 3 smoothly flows out of the heat transfer pipes into the lower header 1b, because the surface tension of the water is reduced when the water is gathered at the tip of the heat transfer pipe at the joined part 5. Thus, the performance to smoothly flow out the water or steam drain is improved and consequently the effect to result in the reduction of damage and deformation accidents of heat transfer pipes due to freezing is improved.

Title: Monitor optical fiber and faulty position detecting method using said fiber
Inventor: KAWASE MASAAKI
IPC: G01M11/00
Filed: 1978-07-10
Abstract: PURPOSE: To secure monitoring at all times for the optical fiber by the presence or absence of the optical pulse reflected by providing previously the uneven points or the light reflecting parts due to the half-mirror and the like to the optical fiber with proper distances.  
     CONSTITUTION: Light reflecting parts 2 are provided to optical fiber 1 with proper distances by the method in which the reflecting material is evaporated to the cross section of the fiber or other methods. As a result, when the optical pulse is transmitted from the terminal of fiber 1, part of the optical pulse propagating within fiber 1 is reflected at part 2. This reflected pulse is measured along the time axis (lateral axis), and thus waveform 5 is observed. In case the fiber is cut off between the No. n and No. (n+1) reflecting parts counted from the measurement end of fiber 1, only n-units of reflected optical pulse is observed. Thus, the cut-off area of the fiber can be detected by counting the number of the reflected optical pulse.
