Title: A process for the manufacture of refined products from hydrocarbon mixtures
IPC: C10G21/08
Filed: 1939-01-07
Abstract: 525,403. Fractioning and/or purifying mineral and essential oils by solvents; reconditioning lubricants. FIFE, J. G. (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). Jan. 7, 1939, No. 602. [Class 91] Mineral oils are desulphurized or are separated into fractions of different saturation or type, used lubricating oils are reconditioned, and essential oils are separated into terpenes or sesquiterpenes and oxygen-containing compounds, e.g. alcohols and aldehydes, by treatment with solvent consisting of pure or commercial antimony trichloride alone or mixed with selective or non-selective organic solvents or with inorganic substances e.g. tetrachloride of tin or titanium or tribromide of antimony ; hydrochloric acid may be present. The oil may first be freed from highly unsaturateds e.g. diolefines e.g. by dilute sulphuric acid; it may previously be dewaxed and/or freed from asphalt ; and dewaxing may follow. The extraction may be with 20-200 per cent. of solvent at 35-180‹C.; it may be in one or more stages, and in countercurrent, double countercurrent, and/or crosscurrent ; it may be conducted as described in Specifications 316,137, [Class 91], 355,294, 380,954, 417,617, and 444,535. Other selective solvents used include cresol, aniline and nitrobenzene for aromatics ; liquid propane, naphtha and gasolene for saturateds; diluents specified are carbon disulphide, benzene, toluene, xylene, and other mono- or poly-cyclic aromatic compounds, e.g. aromatic fractions extracted from gasolene or kerosene. Suitable mixtures are 4 moles. of antimony trichloride with 1 of aniline, and 7 moles of antimony trichloride with 3 of antimony tribromide. The antimony trichloride may be recovered by distillation or by washing with dilute hydrochloric acid. The extraction and the distilling apparatus may be of aluminium, silumin, or " Monel Metal." In one example, a residual lubricating oil is dewaxed and freed from asphalt by liquid propane, mixed at 65‹C. with 50 per cent. by vol. of antimony trichloride, and allowed to stand ; the layers are separated by decantation and freed from antimony chloride by washing with dilute hydrochloric acid. Reference is made to the prior use of antimony trichloride or pentachloride for the chemical refining of oils e.g. as described in German Specification 427,285, U.S.A. Specifications 1,601,753, and 1,760,585; and to the prior use as selective solvents of liquid SO  2 , furfural, cresol, and nitrobenzene.

Abstract: 554,385. Pressure gauges. DOXFORD & SONS, Ltd., W., and NATIONAL PROVINCIAL BANK, Ltd., [Representative of KELLER, K. O.] Jan. 19, 1942, No. 771. [Class 106 (ii)] A device for giving an alarm when the fluid pressure in a system varies from a predetermined value comprises a flexible diaphragm or equivalent movable member subjected differentially to the pressure in the system and to a constant fluid pressure, and a valve movable by said member to admit the fluid which is under constant pressure to an indicator, alarm or other operative device when the loading on the member is unbalanced by a change of the pressure in the system to be safeguarded. Fluid from the system to be safeguarded is admitted into space 11 above diaphragm 13 while a constant pressure such as may be obtained from a supply of compressed air passed through an adjustable reducing valve is admitted into space 12. Normally needle valve 17 closes port 18, but if the pressure in space 11 falls below a pre-determined level, valve 17 opens to admit the constant pressure fluid to a cylinder 19 whereby an alarm device is operated. When compressed air is used, a valve 17 may communicate with a whistle. For use in controlling low-pressure systems a compression spring 23 may also act on the diaphragm. For controlling very high pressures, a tension spring 26, Fig. 3 (not shown), is used. A number of different systems may be controlled from the same supply of contact pressure through differently adjusted reducing valves and differently adjusted springs 23, 26.

IPC: B21J13/12
Filed: 1919-01-11
Abstract: 128,857. Armstrong, Whitworth, & Co., Sir W. G., Trevelyan, F. B. T., and Halliwell, W. Jan. 11, 1919. Blocks acting on drums; actuated or applied by springs.-Relates to work-rotating appliances used in conjunction with hydraulic presses, steamhammers, and the like, in which the work is rotated by a chain driven from a motor through a chain drum, the motor and drum being carried on a frame suspended from a crane hook. In order to allow the motor to continue its movement while the work is held stationary during the forging, the driving means between the motor and the chain drum includes an epicyclic gear, so controlled by a friction brake that the motor rotation can continue while the rotation of the chain drum varies. The friction brake can be adjusted during the operation of the motor element. In the form shown in Figs. 1, 2, and 3 the sun-wheel 6 is mounted on the shaft of the motor 5, and drives planet wheels 7 carried on a cage 8. The cage 8 drives the shaft 17, which, through the gearing shown, drives the chain drum 3. The planet wheels 7 also engage with teeth 11 on a drum 10. The brake blocks 12, 12a, engage the drum 10 and are held by the spring 14 and adjusted by the screw 15, which is controlled by a pulley 16 connected to the ground. The apparatus is suspended from a crane by the hook 2. A magnetic brake 22, 23 is provided for the motor. In other forms, the sun-wheel may be driven from the motor shaft through chain or bevel gearing, and the planet wheels may consist of bevel wheels gearing with the sun-wheel and with the drum 10. In the form shown in Figs. 18 and 19, the normally stationary part of the motor itself is mounted on the shaft of the motor and is held by the brake blocks 12, 12<a>. In this case, the chain drum is driven as before by the rotor shaft and, when the movement of the work is stopped or otherwise varied, the stationary part of the motor moves against the brake blocks. Specification 128,136, [Class 83 (iv), Metals, Working], is referred to.

Abstract: 956, 347. Photo-electric control systems. MINNEAPOLIS HONEYWELL REGULATOR CO. Jan. 8, 1963 [Jan. 12, 1962], No.879/63. Heading G1A. [Also in Division G3] Apparatus for controlling a process variable such as the temperature of a heating process comprises a control instrument having a member 16 which may be moved over a scale 12 by means of gearing 20 to set the operating value of the variable such as temperature, the temperature being sensed by a thermocouple 2 so as to energize a galvanometer 4 having a pointer 10, the pointer 10 carrying a vane 14 which co-operates with a light source 22 and photo-electric cells 26, 28 which are carried on the member 16 to control the temperature to constancy taking into account any variations in the conditions of the system subsequent to the original setting of the operating temperature. The vane 14 is provided with two areas 30, 31, the area 30 co-operating with photo-cell 26 and being clear at one end and opaque at the other end whilst the area 31 is clear at both ends and opaque at the centre and is arranged to co-operate with the photo-cells 28. The photo-cell 26 is arranged in a bridge circuit including thermistors 58, 60 the bridge output controlling a magnetic amplifier 32 so that the output terminals 52 is controlled to constancy when the centre of the vane area 31 is co-incident with the photo-cell 26, the bridge circuit then being in the balanced condition. Terminals 52 are connected to the control member for the process. Should however the process conditions alter such as a change in load or an alteration in the calorific value of the fuel, should the process be a furnace, no adjustment of the set point member 16 is needed since any tendency of the pointer 10 to settle in a false position is corrected by means of the vane area 31 causing one or other of the photo-cells to receive a greater illumination thus causing, by way of thermionic amplifiers 90, 98, 100 heating of either heater 110 or 112 associated with thermistors 58, 60 to reset the bridge circuit including photo-cell 26 in a manner which is proportional to the magnitude and time duration of the changed conditions. The control system may alternatively comprise a pressure sensitive senser and a Bourdon type control instrument.

IPC: F16K3/314
Filed: 1993-01-05
Abstract: PURPOSE:To provide a synthetic resin made gate valve molding method improving-stabilizing the shape accuracy of a cavity part in a valve body. CONSTITUTION:A synthetic resin made gate valve molding method is composed of two processes. In the first process, a reinforcing ring 7 made of metal is fittingly set to a core 6a for forming the cavity part of the valve body housing part 4 of a valve casing 1 and fitted into a metal mold to form a cavity. In the second process, fused synthetic resin is injected in the cavity, and when the injected synthetic resin is cooled to a certain degree, a metal mold on the movable plate side is separated from a metal mold on the fixed plate side. Cores 6a, 6b, 6c are pulled out of the injection-molded valve casing 1, and the valve casing 1 is taken out of an injection-molding device, with the reinforcing ring 7 attached to the surface of the inner cavity part of the valve body housing part 4 of a valve casing mold. The valve casing mold with the reinforcing ring 7 attached to the surface of the inner cavity part of the valve body housing part 4 is then put in a water tank 8 and cooled, and the reinforcing ring 7 is removed.
