Filed: 1975-02-24
Abstract: 1491810 Signalling by sound waves MOBIL OIL CORP 24 Feb 1975 7612/75 Heading G4F In transmitting information from downhole in a well through liquid therein an acoustic signal of constant frequency (e.g. 15 Hz) and phase is generated downhole and the signal is altered by the information to be transmitted to shift its phase (e.g. by -180 degrees) in a time period which produces, when the signal is synchronously rectified, a time for the phase shift effectively equal to zero; the latter condition is met with a time period equal to one normal period of the acoustic signal. Information may be transmitted as a digital word, with signal phase shift being effected in response to designated bits of the word; and information may be transmitted whilst the well is being drilled. In an embodiment housing 11, Fig. 1, within drill collar 12, has a mud turbine 13 which drives an electric generator 14, electricity from which is supplied through control unit 15 to motor 16; the latter drives rotor 17 of a signal generator, valve 18, through drive train 20. Slots 17a of rotor 17 in combination with slots 19a of stator 19 effect repetitive opening and closing of valve 18 to cause an acoustic signal to be generated in the drilling mud. A transducer 22, e.g. a strain gauge, is applied to control unit 15, Fig. 2 (not shown), which includes a digital word generator. Several transducer outputs may be multiplexed. Drive train 20 includes sun and planetary gears &c. whereby a digital "1" information bit causes temporary change of the speed of rotor 17 in accordance with the invention, Fig. 3 to 5 (none shown).

Title: Method of and apparatus for producing stable-dung pulp
IPC: A01C3/02
Filed: 1955-03-22
Abstract: 768,073. Treating stable dung; fertilizers; drainage systems. SCHMIDT, F., and EGGERSGLUSS, W. March 22, 1955, No. 8319/55. Classes 33 and 111. A pump 3, Fig. 1, forces liquid from the lower part of a dung reservoir 2 along pipes 4 to conveying ducts 5 into which stable dung is fed through openings 6. The ducts 5 enter reservoir 2 at the top ; the straw and excremental material remain at the surface -of the reservoir contents ; and it is thus the liquid constituent of the dung itself which is pumped out as the conveying liquid. On completion of the dungconveying process the pump 3 is used to produce in the reservoir 2 a uniform pulpy mass which is thereafter forced by the pump alone a pipe 8 to a silo 9 ; a biological decomposition plant 10 may be interposed. After a time a floating surface, which may become solid, forms on the contents of the silo 9. A pump 11 is used to withdraw thin liquid from the bottom of the silo 9 along pipe 12 and four-way stopcock 21 and return it through one or other of a number of jets d<SP>2</SP>, Fig. 3, on a rotating pipe 13, Fig. 1, to break up the surface when this occurs. Nozzles not required are rendered inoperative by moving downwards the plates s<SP>2</SP> in which they are located. The pulp is withdrawn from the silo 9 by reversing the setting of stopcock 21 and raising one or more nozzle plates s<SP>2</SP> to uncover their respective holes b to serve as suction holes. The flow is then from pipe 13 through stopcock 21 to pump 11 inlet, and from pump 11 outlet through stopcock 21 to pipe 15. The pulp may be discharged either into a tank 14, where chopped straw and artificial fertilizers containing potash, nitrogen and phosphoric acid may be added and the whole circulated by pump 18 through emulsifier 19 prior to discharge to a cart 16 or sprinkler system 17, or directly to the cart or sprinkler system. An alternative path from reservoir 2 to tank 14 is via a manure store 20.

Title: Improvements in or relating to a method and apparatus for atomizing metals or alloys
IPC: B22F9/08
Filed: 1947-03-28
Abstract: 640,457. Atomizing metals; washing granular material. FEDERAL-MOGUL CORPORATION. March 28, 1947, Nos. 8432 and 8433. Convention dates, Feb. 6, 1946. [Class 82(ii)] In a method of and apparatus for atomizing metals or alloys-especially alloys in which copper and lead are the principal components and on which a minimum coating of oxide is desired-in which a fine stream 46 of molten metal or alloy is introduced in a confined space into a stream 34 of water projected at high speed transverse to the molten metal stream and in which space a non-oxidizing or reducing atmosphere is maintained surrounding the said streams, air is flushed from the said space and replaced by a continued introduction of the gas to maintain a pressure within the space slightly greater than atmospheric. A uni-directional flow of water may also be created in the lower part of the confined space into which the atomised metal falls and by which it is solidified and gravitationally separated according to size of particles. The apparatus includes means 74, 84 for dissipating the force of the stream 34 of water subsequent to its atomizing action. In the arrangement shown, molten metal or alloy is introduced into a removable crucible 38 and broken up into a fine stream 46 by apertures 40, falls into the closed container 10 and into contact with the transverse high speed water stream or spray 34 ejected from a nozzle or nozzles 12. The non-oxidising or reducing gas such as nitrogen, hydrogen, helium, or illuminating gas, is introduced from a pressure bottle 24 via the tubes 28, 30, and/or by a tube 32 leading to the interior of the nozzle 12 where the action of the water stream helps to introduce and diffuse the gas in to the container 10. A tube 48 may be provided to confine the action of the water stream on the molten metal, and a glass window 50 may be fitted. The force of the water is dissipated by a perforated screen 74 which also reduces the turbulence of the gas, and by a plate 84 which also serves to direct the atomised molten metal downwardly. and to confine turbulence to the forward portion of the container. Atomised metal falls into a body of water in the lower part of the container where it is solidified and in which a flow is produced by a water inlet 86 to carry particles over the first baffle 82 into troughs 76, 78, 80 where the particles are classified according to size. Depending baffles 96, and water supply nozzles 94 near the bases of the troughs are provided to assist the classifying process, the settled particles being raked into side troughs 100 (not shown)- partitioned at 108-by means of rakes 110. The baffles 84, 96 have apertures 98 near their upper ends to ensure inter-communication between the upper gas-filled parts of the container, whilst a gas outlet 52 and water seal 54 are provided. The Specification as open to inspection under Sect. 91 comprises also the subjectmatter of Specification 648,379. This subject-matter does not appear in the Specification as accepted.
