Title: Improvements in or relating to electric motors
IPC: H02K5/132
Filed: 1940-10-11
Abstract: 545,834. Motors. STEVENS, A. H. (Jackson Co., B.). Oct. 11, 1940, No. 15190. [Class 35] An electric motor particularly of the oil &c. filled submersible type for use at the bottom of a narrow well casing comprises a stator assembly including a number of independently wound stators such as 5, 6 and spacers 13 built into shells 10, 10<SP>1</SP> and a rotor assembly including a number of rotors such as 1, 2, shafting 3, 4 connecting the rotors in axial alignment and bearings such as 46, 52, 55, 67, the rotor assembly of rotors, shafting and bearing means being insertable as a unit into the stator assembly. At the top and bottom of the casings 10, 10<SP>1</SP> are bearing housings 12, 16 and each spacer member 13 has a bore 71 in which engages a cartridge 51 supporting the axial bearings 52, 55 for the shafts the opposite ends of which are held in correct alignment by coupling sleeves 61, 63 keyed to the ends of the shafts and having interengaging jaws 63, 64, one of the sleeves overlapping the shaftends. The end thrust of the whole motor assembly is taken by the thrust-bearing 46 at the lower end of the bearing housing 12 and the casing assembly is rendered fluid tight by gasket 24 at the end of the adjustment rod 17 of the lower bearing housing 16, gasket 22 at the junction of the upper bearing housing 12 and casing 10, and gasket 32 under the seating of the end cover 31. Within the housing 12 is a seal assembly for the shaft 35 comprising a seal housing 38 and mercury filled chamber 38a as described in Specification 520,040, [Group XXVI]. When the motor comprises several stators and rotors the bores in the respective spacer members 13 and the bearing holding cartridges 51 engaging therewith are of slightly diminishing diameter downwardly so that all the interengaging parts of the rotor assembly and stator assembly approach easily until just prior to reaching their final positions, the final movement being under the conditions of a push fit. Electric current enters through a fluid tight cable 87 to a terminal box 88. The motor is preferably of the 3-phase type and the windings of the successive stators all connected in series each winding terminating in rods such as 102, 112 projecting towards one another into the spacer numbers 13 and connected by coupling sleeves such as 122. Besides the power conductors for the three phases a fourth conductor leads to an oil level control terminal 89 which functions in the manner described in U.S.A. Specification 2,002,912, to close a circuit including an alarm or motor cut out if the external liquid entering the casing 21 through the balance tube 75, 76 should rise to contact with the terminal.

Title: Fluid conveying apparatus
IPC: B63B27/34
Filed: 1961-04-27
Abstract: 916,533. Loading fluid cargoes; fluid-pressure counterbalanced apparatus. CHICKSAN CO. April 27, 1961 [May 9, 1960], No. 15193/61. Classes 78 (2) and 78 (4). Apparatus for connecting two containers for the transfer of fluid therebetween, particularly for use between ship and shore, comprises a pipeline supported by a crane-like structure in three pivotally-interconnected sections C, D, E, the first of which is also pivotable about a horizontal axis 30 with respect to a fixed base B, so that the apparatus may, when required, be moved from the position of use shown in Fig. 4 to a lower position of use in which the normally vertical section C extends substantially horizontally as shown in Fig. 7. As shown, the base B is secured to a turntable A on a pier P and the pipeline consists of rigid lengths 20, 32, 40, 46 with swivel couplings between adjacent lengths coaxial with the corresponding horizontal pivots 30, 34, 44 between the frame parts B, C, D, E. When in use loading or unloading a ship 62, slight movements of the latter cause movement of the frame member C, D, E about their pivots, and this movement is resiliently opposed by pressure in hydraulic cylinders 140, 268, 312 connected by cords or chains 132, 242, 300, respectively, to the appropriate sections. For this purpose the pressure in cylinders 140 and 268 are normally held at a constant value sufficient to counterbalance their respective frame members C, D and their cords 132, 242 are wrapped round eccentric cam surfaces 128, 188, respectively, so that the counterbalancing force in each case increases in proportion to the moment of the apparatus about the respective pivot 30 or 34 to retain the apparatus balanced in all operating positions thereof. Deliberate lowering of the section C into the position of Fig. 7 is achieved by reducing the pressure in cylinder 140. Movements of the boom portion D of the framework is effected by an additional pair of cylinders 210 situated one on each side of the framework. Of these cylinders the one shown pulls a rod 208 and with it pulley 206 to cause cable 200 to rotate the boom section D clockwise as viewed in Fig. 7. The other cylinder 210 (not shown) is similarly arranged but is effective to produce anticlockwise rotation of the boom and positional control is achieved by simultaneously pressurizing one cylinder of the pair and venting the other. When not in use, these cylinders are provided with just sufficient pressure to retain the cables 200 in slight tension. A similar provision is made for the control of the movements of the outer arm E of the structure whose movements about pivot 44 are controlled by cylinders 312 through cables 300. The hydraulic control system (not shown) provides independent control of each of the cylinders by the opening or closing of appropriate valves and the requirement for a constant pressure in the counterbalancing cylinders is met by an hydraulic accumulator (not shown) in which the fluid is contained in a reservoir with a movable top cover which supports a constant weight.
