摘要： Impeller means 4 and 5 is provided in a container 2 for agitating fluid. The impeller means is movable to effect fluid flow. The impeller means includes an impeller 4 which is separate from a wall portion of the container to a point of which the impeller 4 is connected by supporting means 5. Movement of the impeller means relative to the wall portion is achieved by making the impeller means flexible.
A vibrator 6 may be provided to cause movement of the impeller means. The characteristics of the components can be chosen so that when the vibrator is activated the impeller vibrates with a greater amplitude than the wall portion 3. This can be achieved by vibrating the wall portion at a frequency approximately equal to a resonant frequency of the impeller means.

摘要： Conduits 8 and 9, 27 and 28 interconnect two compartments. Conduits 8 and 28 of one type together present a lower resistance to flow from one compartment to the other 6than conduits 9 and 27 together and conduits 9 and 27 of the other type together present a lower resistance to flow from the other compartment 6 to the first 7 than the conduits 8 and 28 together. Pressure is varied in one compartment causing fluid to flow between the compartments and the different resistances to flow of the conduits causes mixing without the intrusion of a mixing device from outside the compartments.

摘要： Sea water containing dissolved oxygen is pumped through a main gas ejector (4) supplied with nitrogen. During flow of the sea water and entrained nitrogen from the main gas ejector (4) to an auxiliary gas ejector (5), part of the entrained nitrogen is dissolved and displaces dissolved oxygen from solution. Most of the mixed nitrogen and oxygen collected in a separation chamber (6) is passed through a catalytic burner (7) to remove the unwanted oxygen which is replaced by nitrogen from a topping-up source (9) and the resultant nitrogen mixture is fed to the main gas ejector (4) which is operated so as to provide sufficient suction to draw gas through the catalytic burner (7). Part of the mixed nitrogen and oxygen collected in the separation chamber (6) is fed to the auxiliary gas ejector (5) which is operated so as to increase the gas to liquid interface. Sea water and entrained nitrogen flow from the auxiliary gas ejector (5) to the separation chamber (6) through a stepped desorption tube (3) which causes additional turbulence and retards the flow of sea water, thereby enhancing the solution of nitrogen and removal of oxygen. Sea water with reduced disssolved oxygen is continuously removed from the separation chamber (6).

摘要： In a fluid flow device, fluid flows from an outer conduit (17) to an inner coaxial conduit (16) through a communicating chamber (21) at one end of the conduits. In order to prevent turbulence in the fluid flow due to the change of axial direction, vanes (25 to 28) are provided, some of the vanes (25 and 26) which extend into the communicating chamber. Preferably some of the vanes extend continuously from the outer conduit through the communicating chamber to the inner conduit. A flow straightener (15) may also be provided downstream of the vanes in the inner conduit.

摘要： Dans un dispositif à écoulement de fluide, un fluide s'écoule d'une conduite externe (17) vers une conduite coaxiale interne (16), à travers une chambre de communication (21) à une extrémité des conduites. Afin d'empêcher toute formation de turbulences dans l'écoulement du fluide à la suite d'un changement de la direction axiale, des ailettes (25 à 28) sont montées, dont quelques unes (25 et 26) s'étendent dans la chambre de communication. De préférence quelques unes des ailettes s'étendent en continu de la conduite externe à travers la chambre de communication vers la conduite interne. Un redresseur d'écoulement (15) peut également être disposé en aval des ailettes dans la conduite interne.

摘要： Des conduits (8 et 9, 27 et 28) relient deux compartiments. Les conduits (8 et 28) d'un type présentent une résistance à l'écoulement d'un compartiment (7) à l'autre (6) inférieure à celle des conduits (9 et 27) et les conduits (9 et 27) de l'autre type présentent une résistance à l'écoulement de l'autre compartiment (6) au premier compartiment (7) inférieure à celle des conduits (8 et 28). On fait varier la pression dans un compartiment, ce qui provoque l'écoulement du fluide entre les compartiments et les différentes résistances d'écoulement des conduits provoquent le mélange sans pénétration d'un dispositif de mélange depuis l'extérieur des compartiments.

摘要： A high pressure abrasive jet is created by feeding a mixture of carrier liquid abrasive material at high pressure through a conduit to a nozzle (222). The mixture may be formed at said high pressure. Valves (211, 212) which carry the high pressure mixture are provided with a trap (204, 208) above and a settlement volume below so that when flow stops, the abrasive material can settle from under the trap entirely into the settlement volume, thus leaving the valve to operate in clear carrier liquid. A high pressure abrasive jet can be formed by feeding carrier liquid and abrasive material into a vertically extending conduit leading to a nozzle at its lower end, the high pressure being generated by the head of the conduit's contents.

摘要： The water conduit (4 and 5) is formed with a plurality of radially adjacent coaxially arranged tubular parts (4 and 5) which are serially connected by semi-toroidal bends provided by baffle plates (8) extending between each pair of radially adjacent coaxially arranged tubular parts (4 and 5) and an adjacent fairing (9) mounted on the radially inner tubular part of each said radially adjacent pair of coaxially adjacent tubular parts (4 and 5). Each baffle plate (8) has an outer peripheral portion (12) which is curved so as to cooperate with the adjacent fairing (9) to provide a curved water path. A hollow centre body (18) is supported by a further conduit (20) for longitudinal movement within the outlet nozzle (7) of the water conduit (4 and 5) and a branch pipe (21) from the inlet means (6) to the water conduit (20). This water issues from outwardly directed openings (23) in the centre body (18) to vary the flow through the outlet nozzle (7) and is controlled by a valve (22) in the branch pipe (21).

摘要： De l'eau de mer contenant de l'oxygène dissous est pompée au travers d'un éjecteur principal de gaz (4) alimenté en azote. Pendant l'écoulement de l'eau de mer et de l'azote entraîné depuis l'éjecteur de gaz principal (4) vers un éjecteur de gaz auxiliaire (5), une partie de l'azote entraîné est dissous et déplace l'oxygène dissous de la solution. La plus grande partie de l'azote et de l'oxygène mélangés et recueillis dans une chambre de séparation (6) passe au travers d'un brûleur catalytique (7) pour éliminer l'oxygène non désiré qui est remplacé par de l'azote provenant d'une source (9) rétablissant le niveau et le mélange d'azote résultant est envoyé à l'éjecteur de gaz principal (4) qui est actionné de manière à produire une aspiration suffisante pour entraîner le gaz au travers du brûleur catalytique (7). Une partie de l'azote et de l'oxygène mélangés et recueillis dans la chambre de séparation (6) est envoyée vers l'éjecteur de gaz auxiliaire (5) qui est actionné de manière à accroître l'interface gaz/liquide. L'eau de mer et l'azote entraîné s'écoulent de l'éjecteur de gaz auxiliaire (5) vers la chambre de séparation (6) au travers d'un tube de désorption en escalier (3) qui provoque des turbulences supplémentaires et retarde l'écoulement de l'eau de mer, améliorant ainsi la solution de l'azote et l'élimination de l'oxygène. De l'eau de mer à teneur réduite en oxygène dissous est extraite en continu de la chambre de séparation (6).
