Abstract: 1,139,319. Centrifugal pumps. ACF INDUSTRIES Inc. July 12, 1966 [Aug. 6, 1965], No.31232/66. Heading F1C. [Also in Division H2] A submersible centrifugal pump comprises a cylindrical motor casing 19 formed with a support 23 for a lower bearing 26, the bearing being held in place by spring fingers 27. An outer cylindrical shell 46 into which the casing 19 is slid is provided with a similar arrangement for the upper bearing 28. The pump casing 83, of moulded plastics or cast metal, is provided with a castellated projection 92 which is inserted into the shell 46 to abut the bottom of the motor casing 19. Lock tabs 52 formed on the shell 46 are then bent inwards so that their upper bevelled surfaces engage the bottom of the motor casing 19 to hold it within the shell. Fingers (57), Fig. 3 (not shown), extending upwardly from a retainer plate 54 to embrace the pump casing 83 are bent inwardly to engage lips (50) on the shell 46 adjacent the lock tabs 52, thereby holding the pump casing in place. A filter assembly 61 comprises a screen 71 held between plates 63 and 68, and a cylindrical screen 74 held by the rim 64 of the plate 63. At its upper end, the screen 74 is clamped by a ring 77 against a seal ring 76 which embraces the shell 46. The discharge conduit 13 passes through the seal ring 76 and is supported by a bracket 14; a locating collar 99 may be provided. The seal ring 76 is provided with a vent tube (103), Fig. 6 (not shown), for discharging vapour accumulating in the annular space 75.

A structure for subaqueus oil exploitation has a shaft 101 attached by a universal joint 67 to a tank 50 and supporting pipes 80, each pipe conducting oil to a platform 66 or being used as a drilling-string conduit. The tank has an open bottom and houses a vessel 51 with a skirt 54 fixed to the peripheral wall 56 of the tank by radial tubes 55, said wall being partially filled with concrete for ballasting purposes and so as to leave a space 60. The shaft 101 comprises either a single tube, Fig. 8 (not shown), or tubular portions 102, 104 and a trussed portion 103. When transporting the structure to the site the vessel 51, the space 60 and the upper part of the tank are filled with air to render the tank buoyant, the upper end of the shaft being temporarily filled with water, Fig. 16 (not shown). To sink the tank the interior thereof and the space 60 are flooded and the water in the shaft is expelled, whereafter the vessel 51 is flooded in two stages, Figs. 17 to 20 (not shown). The pipes are then slid through guides 81 and holes in a ring 57. The portion 102 may be filled with concrete or be used to store oil. The portion 104 provides buoyancy to keep the shaft erect. When shaft includes a single tube the latter may be used for oil storage, ambient water being given access to the lower end of the tube. Alternatively, the tube is partially charged with water or filled with compressed air to equalize pressures. The vessel 51 may be omitted and the bottom of the tank closed, Figs. 3 to 7 (not shown), in which event the tank may store oil and be secured by piles. The tank may be replaced by a weight of similar shape, Figs. 1 and 2 (not shown), or a pile. The pipes may pass through the interior of the shaft, Fig. 2.
