Title: Improvements in and relating to electric control systems
IPC: G05D3/14
Filed: 1945-05-25
Abstract: 592,766. Inductive relays. BRITISH THOMSON-HOUSTON CO., Ltd. May 25, 1945, No. 13203. Convention date, May 25, 1944. [Class 40 (iv)] [Also in Group XXXVIII] In a correspondence control system, the saturation of two saturable reactors, controlling a follow-up motor, is varied in accordance with deviations from correspondence by D.C. signals proportional to the deviation. The Figure shows an arrangement in which any lack of correspondence between the arms of potentiometers 13 and 14 coupled to control (11) and follow up (10) members causes a current to flow through saturation control windings 18d and 19d of saturable reactors 18 and 19, thus varying the impedance and hence the current through windings 18b and 18c and 19b and 19c which are respectively connected in series with the two two-phase half-wave rectifier systems 26, 27 and 28, 29 and the common centre tapped transformer 20. The output current of rectifier circuit 26, 27 for example flows through positive feedback winding 18g, the coil of relay 23, contacts 25c of relay 25 and compensating control windings 18c and 19c connected in parallel with a resistor. Windings 18d and 19d are arranged to vary the saturation of reactors 18 and 19 in opposite senses, so that when the deviation between potentiometers 13 and 14 exceeds a predetermined value one of relays 23 and 25 lifts, closing either of contacts 236 and 256 so that if line 53 is energized (i.e. switch 43 is in the automatic position) split field motor 12 is energized and runs to bring potentiometer 14 and member 10 into correspondence with the controlling member. The closing of contacts 236 causes a current to flow through an antihunt winding 18y which reduces saturation, so that relay 23 cuts in and out as correspondence is approached, similarly for reactor 19 and relay 25. Trimming resistors 44 and 45 are connected in series with potentiometer 13, also the motor 12 may be directly operated by setting switch 43 to energize line 54 or 59. The arrows on the reactors indicate the direction of the fluxes produced by the respective windings.

IPC: C01B31/12
Abstract: 133,452. Broxburn Oil Co., and Findlater, R. H. Oct. 11, 1918. Carbon.-The carbonaceous residue of the distillation of bituminous shales, cannel coal, &c. is ground, washed, and digested with sulphuric, hydrochloric, nitric, or hydrofluoric acid in a digester 5, the mixture is filtered in a press 13, and the filter-cakes digested in a digester 60 with caustic soda, the carbon being filtered off in a press 63 and washed with water, dilute acid, and then water. Alternatively, the material may be treated first with acid, as described above, then with sodium carbonate, in which case some silica separates on cooling, and then with caustic soda. The acid extract collected in tanks 11 is filtered in a press 18 to remove any calcium sulphate which separates during cooling, and is then passed to saturators 24 arranged in two groups A, B and C, D used alternately. Ammoniacal gases which may be derived from the shale distillation are passed in by a pipe 26 to the lower saturator A, the outlet gases passing by a pipe 27 to the saturator B, leaving finally at 28. When the liquor in A is filtered in a press 33, the liquor from B is passed into A, and fresh liquor is run into B. Alternatively, ammoniacal liquor may be used for this precipitation. The press-cakes from the press 33, consisting of alumina and iron hydrate, are digested with caustic soda in a digester 39, iron hydrate being filtered off in a press 42, and sodium aluminate solution being passed through a tank 46 and pipe 48 to towers 49, in which it is treated with gases containing carbonic acid, the alumina being finally separated in a press 53, while the sodium carbonate may be caustified for re-use. Any ammonia evolved in the digester 39 is passed by a pipe 67 into the saturators. The caustic soda extract from the digester 60 is concentrated for sale as sodium silicate. The ammonium salt solution from the press 33 is withdrawn at 35 and evaporated.

Abstract: 1,086,881. Boring earth; wells. CHEVRON RESEARCH CO. March 31, 1965 [April 1. 1964], No. 13770'65. Heading E1F. During drilling, or working on, an underwater well from a floating vessel 1 through a marine conductor 15 the buckling of the conductoir due to the material contained therein is prevented by applying a tension to the conductor in addition to any tension which may be applied to prevent buckling of the conductor for other reasons such as displacement of the vessel, movement of the water, or weight and loading of the conductor. The tension to compensate for the weight of the material contained 'in the conductor is equal to the weight in water of the material which may be drilling fluid with, or without, drill pipe or casing. The top of the conductor is supported laterally in the shaft 3 of the vessel and has a part 54 biassed into contact with the vessel. Below the part 54 the conductor has a flexible joint 49 which is above a telescopic joint 50. The lower end of the conductor has a ball joint 48 and is connected to the wellhead 20, which includes blowout preventers 22, 23 and a connector 24 by means of a connector 45. The total tension may be applied through cables each connected at one end to the conductor and at the other end to either a constant tension winch on the vessel or to weights suspended over pulleys on the vessel. As shown the total tension is applied by a float 90 which may be supplemented by a second float, but in modifications the buoyancy of the float is supplemented or replaced by forming the conductor with a double wall. The tension may be reacted by the connection of the wellhead to the bed 11 or it may be wholly or partly reacted by a ring 110 connected to the conductor to be level with the ball joint.

Abstract: 699,151. Heating granular materials for use as heat transmitting-media. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. June 13, 1951 [June 15, 1950] No. 14012/51. Class 64 (ii) A fluidizing gas, e.g. hot combustion gases for heating a medium flowing in pipes 9, is dispersed by a bed 6 of a particulate solid surrounding a gas inlet 2, the particle size of the bed material being larger than that of the mass 7 which is to be fluidized and which is supported by the bed. Moreover the mass 7, e.g. of dune sand, when quiescent, rests mainly or wholly on a permeable partition 5 located immediately above and serving to restrain the bed material from displacement relative to the containing vessel during operating. The sand acts.as an intermediary for the transmission of heat from the fluidizing gas to the pipes 9. The particles of the bed 6 in the main have a maximum dimension between 2 and 10 mm. and the partition 5 covering the bed is perforated with 2 mm. openings. These particles, e.g. of gravel or granulated rock, are angular or irregular in shape, are of higher specific gravity than the mass 7 to be fluidized and may be cemented together, by surface fusion, chemical means or a cement, at least in the upper part of the bed 6. The grains of the fluidized mass 7 have an average maximum dimension of 180 microns. A cap 3 deflects the burner combustion gases leaving each inlet 2 and these gases pass out of the cylindrical vessel 1 by an outlet 8.

Abstract: 543,750. Drawing wire. HYDRAWMAT MACHINE CORPORATION. Sept. 10, 1940, No. 14052. Convention date, Dec. 7, 1939. [Class 83 (iv)] In wire drawing apparatus in which an independently driven drum is located after each die, the danger of breakage of the wire is reduced by applying an initial loading, which is insufficient to start the movement of the wire. The load applied to the first drum is less than the resistance of the first die, and a load is applied to each succeeding drum which is greater than that necessary for pulling the wire through the associated die, the total force exerted being substantially equal to the total resistance of the dies. A small increase in the load applied to the last drum will then effect movement of the wire. The drums are driven by separate fluid-operated turbines 9. 10, 11, the jet-nozzles 12, 12a of which have independent regulating-valves.
