02 Jul 1984TL;DR: In this paper, an improved version of an improved storage and reclamation apparatus with a downwardly facing bell mouth coupled through a pipe to a pump is described. But it does not handle the overflow from the tank into a second tank which has a second bell mouth mounted at the bottom of the tank.
Abstract: This is an improved apparatus used with a storage and reclamation apparatus which handles slurry formed of particulate matter and fluid. The reclaim apparatus includes a tank having a side wall and bottom. The slurry is added into the tank and is subsequently removed from the tank by a downwardly facing bell mouth coupled through a pipe to a pump. Fluidizing jets surround the bell mouth with a dilution control port mounted between the mouth and the pump. The dilution control port is connected to a second pump in series with a source of fluids. Process control apparatus measures the flow and density of the material being drawn into the mouth and adds or reduces dilution fluid in accordance with a set point so that a constant density is maintained at all times. The improved version accepts the overflow from the tank into a second tank which has a second bell mouth mounted at the bottom of the tank. Solids and fluids are sucked into the second bell mouth and used as the source of fluid for the dilution port of the first tank.

TL;DR: In this article, the main body of a turbine can be operated under both wet and dry gas conditions by a method wherein moving blade and stationary blade can be fixed and removed in respect to the turbine.
Abstract: PURPOSE:To enable one main body of a turbine to be operated under both wet and dry gas conditions by a method wherein moving blade and stationary blade can be fixed and removed in respect to the main body of the turbine. CONSTITUTION:A rotor 5, casings 1, 2 and 3, and an inlet bell mouth 4 which constitute the main body of turbine are of such a structure and size as enabling its operation under both wet and dry gas conditions. To the rotor 5 are removably attached moving blades 6 and to the inner casing 3 are also removably attached stationary blades 7. When the gas condition is to be varied, the turbine can be operated only with a replacement of the moving blades and the stationary blades.

TL;DR: In this article, an annular body, having arced curved surface, is formed at the tip end part of the fan to form a smooth air introducing path by the ANNular body and a suction port having the shape of bell mouth.
Abstract: PURPOSE:To reduce noise by a method wherein an annular body, having arced curved surface, is formed at the tip end part of the fan to form a smooth air introducing path by the annular body and a suction port having the shape of bell mouth CONSTITUTION:The annular body 4a, having the curved surface of the shape of arc, is formed at the tip end of the fan 4 The smooth air introducing path is formed by the annular body 4a and the suction port 3d of the shape of bell mouth According to this method, when air flows from the suction port 3d of the fan case 3 into the fan case 3, the flowing air passes the suction port 4c of the fan 4 smoothly without causing any turbulence as shown by arrow signs B and, then, flows into the fan case 3 through spaces between blades 4b Accordingly, noise may be reduced remarkably
