Title: Improvements relating to hydraulic turbo couplings
Inventor: BASEBE ARTHUR CECIL
IPC: F16D33/12
Filed: 1959-09-07
Abstract: 912,670. Hydraulic couplings. SINCLAIR, H. Sept. 1, 1960 [Sept. 7, 1959], No. 30518/59. Addition to 799,234. Class 69 (2). The valve 30 responsive to a decrease in filling of the working circuit of the hydraulic turbo coupling described in the parent Specification to increase the rate of the restricted flow therefrom is modified and comprises a first float 37 coupled to a valve member 33 and movable relative to the coupling axis to actuate the member in accordance with the radial depth of liquid in the reservoir chamber 11, and a second float 39 also coupled to the valve member and movable in a float chamber in which, while the coupling is in operation, liquid is maintained at a substantially constant depth. The working circuit is formed by a casing 4 secured to an impeller 1, input shaft 8 and the reservoir 11, and contains a runner 9 secured to an output shaft 10. Liquid discharged from the working circuit through leak-off nozzles 21 and the valve 30 passes to the reservoir chamber 11 from which it is conveyed by an adjustable scoop tube 15 to a cooler and returned to the working circuit through a duct 22, chamber 24 and ports 25. More than one valve 30 may be provided and each consists of a member 33 controlling orifices 40A, 40B, 40C in a cylinder 32 and connected by a rod 34 to a disc 35 secured to the first float chamber 37, which is of annular form, and to the second float chamber 39 which is disposed in the chamber 38. The cylinder 32 is secured to a second cylinder 31 disposed between the easing 4 and reservoir 11 and formed with ports 41 . . . 44. During normal operation with the working circuit full and the scoop tube 15 in its radially-outermost position, the liquid in the working circuit can pass through the leak-off nozzles 21 and through a restricted path consisting of ports 45, 46 to the interior of the cylinder 31 and through ports 41 . . . 44 to the reservoir chamber. Some liquid passes through ports 36 in the plate 35 to fill the chamber 38. The liquid in the reservoir chamber 11 is of insufficient depth during normal operation to move the member 33 from the position shown so that the orifices 40A, 40B, 40C are closed. When the scoop tube is moved to empty the working circuit, the increased depth of liquid in the reservoir chamber acts on the float 37 to move the member 33 and successively open the orifices 40A, 40B, 40C to increase the flow from the working circuit to the cooler. In an alternative embodiment, the member 33 and cylinder 32 are replaced by a conical member cooperating with a hole in a disc.

Filed: 1961-08-24
Abstract: 1,002,540. Gyromagnetic resonance apparatus. CALIFORNIA RESEARCH CORPORATION. Aug. 24,1961, No. 30547/61. Heading G1N, In a free precession nuclear magnetic resonance well logging arrangement, remanent fields arising from metallic deposits or metal in the drilling fluid on removal of the polarising field are compensated or eliminated by the application of reverse or diminishing alternating fields respectively, subsequent to the switch off of the polarising field. In the arrangement of Fig. 1 application of the polarising field by coil 12, which serves also to pick-up the resonance signal is controlled by push-button 44 through a relay 16, contacts 18 of which connect the polarising battery 39 in one position and compensating battery 36 in the other, the precession signal being applied to oscilloscope 51 through blocking condensers 48, 49 and an amplifier 47. Experiments to determine the strength of the compensating signal by applying over-compensating signals are described. In an alternative arrangement an additional threeposition double-pole switch may select for connection to the coil, the compensating voltage, a relaxation voltage, or neither. In a further alternative arrangement described with reference to Fig. 7 (not shown) a capacitor is connected across the polarising coil so that an oscillating current is set up at switch off, the frequency of oscillation being substantially higher than the expected former frequency and the decay time being sufficiently short that precession may be detected. A thyrite resistor or a plurality of cold cathode tubes may be shunted across the coil to control the decay time. A multiple switching arrangement for periodically or cyclically reversing the polarising current flowing in the field coil after initial interruption of the main current source is described with reference to Fig. 12 (not shown).

Title: Improvements in or relating to the production of carbon black
IPC: C09C1/56
Filed: 1950-12-22
Abstract: <PICT:0689134/III/1> In the production of carbon black of the type where an axial stream of hydrocarbon in gaseous form surrounded by a helically moving blanket of hot gas is passed into a reaction zone, the hydrocarbon in the axial stream is fed at a rate so high that an increased yield of tarry unacceptable black results and this black is detarred to produce tar-free carbon black.  The hydrocarbon employed is preferably a gas oil and the hot gas forming the helically moving blanket may be formed by the combustion of methane and air.  Air alone may be injected through tangential ports to burn a portion of the axial stream to form the blanket or a mixture of air or free oxygen containing gas and any fluid fuel of liquid, gaseous or granular nature may be used.  The resulting carbon black may be detarred by treatment with chloroform or acetone but the detarring is preferably effected by oxidation with air at 400 DEG -1200 DEG F, as shown in Fig. 2.  Carbon black produced in a furnace 16 and cooled in cooler 43 before collection in collector 46, is passed to a conveyer 49, a portion of the black may be pelletted if desired by withdrawal through pipe 53 and pelletting as described in Specification 638,863, before passing up elevator 67 to join unpelletted black fed through pipe 51 directly from the conveyer 49 in the hopper 68, feeding to the p  detarring drum 72.  Air entering at 86 and preferably mixed with oxygen-lean air recycled from the process, is preheated to 400 DEG -1200 DEG F in 88 and passed to drum 72, a portion of the effluent from which may be recycled directly or through the heater 88.  The detarred carbon black is withdrawn from line 79 to a bin 82, or passed to a flushing drum 77 and flushed with an inert gas such as nitrogen, carbon dioxide, hydrogen or oxygen at a temperature low enough to prevent oxidation.  The product is then collected in bin 84. 0.1 to 5 per cent of sulphur dioxide may be added as an oxidation catalyst from tank 103 to the air entering at 86.  The black, if desired, may be simultaneously detarred and pelletted in drum 72. Reference is also made to detarring carbon black by treating it in a fluidized bed with 97 per cent nitrogen and 3 per cent oxygen by volume.  Specifications 607,296, 621,031, 649,091, 670,227, 679,818 and 689,141, also are referred to.

Abstract: 719,920. Photosensitive vesicular diazotype print material. GENERAL ANILINE & FILM CORPORATION. Dec. 11, 1952 [Dec. 12, 1951], No. 31410/52. Class 98(2) A solution of 5 to 1 parts of a thermoplastic hydrophobic resin such as polyvinyl acetate or polymethylmethacrylate or of a cellulose ester such as the acetate or nitrate, and 1 to 6 parts of a resinous copolymer made from a vinyl compound such as methyl-, isobutyl-, 2-methoxy-ethyl- or 2-ethoxy-ethyl-vinyl ether and maleic anhydride or this when substituted by a lower alkyl group, is coated on a support and dried to give a clear layer, and the layer is treated with a moist water soluble nitrogenous base, usually aqueous ammonia vapour, to make the copolymer hydrophilic. and then photosensitized by application of an aqueous solution of a stabilized diazo compound and, finally, dried. Irradiation of the material with actinic light through a design and then subjection to an elevated temperature develops an image and reduces the water sensitivity of the layer. If desired the print may be re-exposed to light to destroy remaining diazo compound. Clean whites with soft tone gradation result. In Example 1 specified proportions of cellulose acetate and a vinyl methyl ether-maleic anhydride capolymer, with polyvinyl methyl ether as plasticizer, dissolved in a mixture of ethylene glycol monomethyl ether and acetone are coated on black paper, dried, and the material is passed through ammonia vapour several times at 180F., washed with dilute HC1. dried at 50C., sensitized by immersion in an aqueous ethanol-ethylene glycol solution of N,N-diethylaniline -4-diazonium chloride zinc chloride double salt acidified with citric acid, and again dried. On exposure through a positive transparency to ultraviolet rays and development by sudden application of heat, as by use of a rotary ironing mangle at 347F. a stable image with soft gradation and good moisture resistance results. Exposure to direct actinic light destroys the remaining diazo compound without adversely affecting the prints. Nine further examples specify further copolymer coating formulations for use by the procedure of Example 1. If a transparent support as of glass or regenerated cellulose is used a negative print results.
