Abstract: Static mixers are arranged so that its longitudinal direction is substantially vertical. A liquid supply mechanism supplies the liquid containing impurities from the upper end of the static mixer into the static mixer. A gas supply mechanism supplies gas from the lower end of the static mixer into the static mixer. The static mixer is fabricated so that one or more mixing elements comprising a passage tube through which fluid can pass and one or more spiral blades arranged inside the passage tube are, continuously or through one or more spacers, arranged in the longitudinal direction thereof. The liquid drops down inside the static mixer and the gas rises up inside the static mixer, so that the two are subjected to gas-liquid contact inside the static mixer.

A static type fluid mixer includes a passage pipe for the passage of a fluid and a spiral blade body arranged in the passage pipe with the longitudinal direction substantially perpendicularly but being absent in the center portion of the passage pipe. A liquid and a gas are supplied into the static type fluid mixer and a fluid is returned from the bottom portion of the static type fluid mixer to the upper portion via the pipe for the fluid circulation. The fluid is maintained in the static type fluid mixer at a pressured state higher than the atmospheric pressure.

Abstract: A mixing element comprises a cylindrical passage pipe through which a liquid flows, and a plurality of blade bodies disposed inside the passage pipe. The blade bodies forms inside the passage pipe a plurality of fluid passages extending spirally and in a longitudinal direction of the passage pipe. And, a gap between the blade bodies forms an opening for communicating the fluid passages to each other. These spiral blade bodies are produced independently to the passage pipe, after that, they are joined to an inner face of the passage pipe. Thus produced fluid fixer has an extremely high mixing-agitating effect.

Abstract: Holes are formed in boundary portions of a blade member between first blade sections which are spirally twisted in a clockwise direction, between second blade sections which are spirally twisted in a counterclockwise direction and/or between the first and second blade sections thereof. Thus, the blade sections are joined to each other at portions lying on both sides of the hole. That is, the first and second blade sections are joined at two points or on both side portions and therefore the mechanical strength of the blade member is high.When the fluid passes from the first blade section into the second blade section or passes the boundary portion between the first or second blade sections, it passes the hole formed in the central portion. When the fluid flows along the spiral fluid path, it flows with a turning movement and moves between the center and the side wall of the tubular member.

Abstract: While the work-mounting sections of the work mounting member is intermittently rotated around the circle by a driving mechanism, works are fed to the work mounting sections at the first position by a work supplying device, predetermined liquid mixture is injected to and applied on works, at the third position, by a injecting mechanism, and those works which have been applied with the liquid mixture are discharged from the work mounting sections, at the second position, by a work discharging mechanism. Upon completion of injection of the liquid mixture in the works, the work mounting sections is moved and is stopped when the next work comes to the third position, and the liquid mixture is likewise injected to and applied on the work. The above operation is repeated, so that injection of the liquid mixture to works, supplying works onto the work mounting section and discharging them therefrom are sequentially executed while the work mounting sections are intermittently rotated around the circle.

Abstract: A mixing element according to this invention comprises a passage tube through which fluids to be mixed pass, a fluid structure providing a plurality of fluid passage in the interior of the passage tube, and an auxiliary body disposed on the inner wall surface of the passage tube and at least a part of the surface of the fluid passage structure, whereby the area in contact with the fluids and the shearing force are increased, whereby the mixing effect is improved.

Abstract: A blade is formed integrally on the inner peripheral surface of a cylindrical passage tube, thus constituting an element. A porous or meshed auxiliary body is disposed on the surface of the blade or the inner peripheral surface of the passage tube. The auxiliary body serves to increase the area in contact with the gas flowing through the element and to accelerate capture of particulates in the gas.

Abstract: An element of a sound arresting device has a cylinder and a blade integrally formed in the cylinder and helically twisted along the longitudinal direction of the cylinder. A plurality of elements are coupled to each other along their longitudinal direction and are fitted in a pipe. The ends of the two adjacent blades are perpendicular to each other. The pipe is covered with a sound insulating material. The elements and the pipe are made of a porous metal material, a porous plastic material or a porous ceramic material. When the sound arresting device is used as an automobile muffler, acoustic waves propagating in the gas are repeatedly mixed, interfere with each other and are absorbed by the apertures and the sound insulating material, thereby decreasing noise from the engine. Dust in the exhaust gas is captured by the apertures of the elements and the pipe, and is removed from the exhaust gas.

Abstract: A mixing element for a motionless mixer comprises a passage tube through which fluids flow and a helical blade formed in the passage tube so as to be integral therewith. The interior of the passage tube is partitioned by the blade to form a plurality of fluid passages. The blade extends from one end of the passage tube to the other in the longitudinal direction of the passage tube to be twisted helically clockwise (right-handed) or counterclockwise (left-handed). The corner portions of the fluid passages are rounded. The end edges of the blade are curved in the direction of the thickness and rounded. The motionless mixer is formed by alternately and longitudinally coupling right- and left-handed rotation type mixing elements. The mixing elements are so arranged that the facing end edges of the blades of each two adjacent mixing elements cross at right angles.

Abstract: A method of manufacturing brazed parts by brazing a metal part with a base material made from a metal plate on which a pressing operation is accomplished at a work station. The base and filler materials are stamped with the filler material initially on top of the base material. A portion of the filler material is formed through and held in position in a through hole in the base material. The metal part and the base material are then brazed through the filler material.
