Title: Improvements in or relating to centrifugal pumps
IPC: F04D13/08
Filed: 1931-09-25
Abstract: 372,672. Centrifugal pumps. LAFONT, L., 32, Place Sebastopol, Lille, Nord, France. Sept. 25, 1931, No. 26804. Convention date, Oct. 4, 1930. [Class 110 (i).] A multi-stage centrifugal pump which is arranged vertically and driven by an electric motor, has a plate keyed to the pump shaft upon which the delivery water pressure acts to raise the pump and motor shafts off the bottom thrust bearing. The pump 9 delivers water, from an inlet 19, through conduits 20, 21, to an outlet 22. Part of the delivery water enters a chamber 24 and presses upon the side of a plate 14 and causes the pump shaft 4 to be lifted off the thrust bearing 6. The motor shaft 3 is connected to the pump shaft by a flexible coupling 5. The stator 8 dips into an oil, or other insulating fluid, bath and is insulated from the rotor by a cylindrical partition 13. Water leaking past the plate 14 enters a chamber 17 and acts as a lubricant by passing through grooves in the plain bearings 11, 11<1>. This water afterwards passes through the air gap between the rotor 7 and stator 8 for cooling purposes and afterwards through grooves in the bearing 11<2>. The discharge of this water is regulated by a needle valve, or alternately, a needle valve may be provided in the chamber 17. The electric motor may be situated on the suction side of the pump. The electric motor may be replaced by another form of motor.

Filed: 1927-10-14
Abstract: 279,826. British Thomson-Houston Co., Ltd., (Assignees of Hoxie, C. A.). Oct..- 30, 1926, [Convention date]. Optical apparatus and record.-Sound is recorded photographically on a moving blank so as to produce a record which in addition to varying in density longitudinally of the record strip in accordance with the sound also varies in density transversely The method of producing the record permits the use of a relatively narrow slit and avoids tha necessity for very fine adjustment of such slit. In making the record, apparatus such as described in Specification 180,296 is employed wherein actinic rays from a source 9, Fig. 1, are directed on to a mirror 12 which is vibrated by the sound and reflects the rays through a cylindrical lens 13 whereby they are focussed on a slit 4 behind which the record 1 is moved. According to the invention, a screeen is inserted between the screen 9 and the lens 10, and in one arrangement the screen 17, Fig. 1, gradually varies in transparency from opaque at one vertical edge to clear at the other so that the beam of rays reacted through the slit varies in density from one edge to the other and is vibrated in accordance with the sound parallel to the length of the strip. Fig. 4 shows the beam falling on the slit plate 3, the slit 4. and the record 16 produced at one side of a picture film. In another arrangement, the screen 17 is replaced by an opaque screen arranged near to, and partially intercepting the beam passing to, the lens 10.

Title: Improvements relating to the coating of electrically conducting bodies
Inventor: ALSTON MERVYN WILLIAM
IPC: C25D13/22
Filed: 1960-08-10
Abstract: 921,938. Coating metal bodies, electrophoretically. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 28, 1961 [Aug. 10, 1960], No. 27730/60. Class 41. The face of a metal body e.g. a cathode or rod is coated electrophoretically from a suspension of a solid coating substance, by bringing the face into contact with the surface of the liquid, withdrawing it slightly to form a short column of liquid below the surface and drawn up by surface tension, and then applying a potential between the metal body and an electrode immersed in the liquid. The body is then wholly withdrawn dried, and the solvent driven off by heating. The process may be used to apply active coatings of alkaline earth carbonates suspended in a binder e.g. methyl methacrylate, or to coating the end of a tungsten or molybdenum rod with finely powdered glass. By this means only the end face is uniformly coated and is free from thickening at the edges. In a suitable apparatus comprising a bath containing a suspension 3 in which an electrode 4 is mounted, the cathode rods are attached to magnetized pins 51 mounted on a plate member 43. This is slidably connected to an upper plate member 42 rigidly attached to a rod 31. In operation, the two plate members are lowered by rack and pinion 32, 33 until the cathode ends contact the surface of the liquid. The lower plate member 43 is then raised a little by arms 48, so that the ends of the cathodes are raised about <SP>1</SP>/16 inch. Current is then applied to electrode 4 and member 43, and the suspension is agitated by a magnetically controlled stirrer 18. The subsequent heat treatment of the coated cathodes converts the carbonates to oxides. Specification 839,504 is referred to.
