Title: Charging apparatus for furnaces
Inventor: GREAVES MELVIN J
IPC: F27D3/00
Filed: 1961-02-13
Abstract: 915,499. Feeding charges. INLAND STEEL CO. Feb. 13, 1961, No. 5295/61. Class 78 (1). [Also in Group XII] In a charging apparatus 10, interposed by a passage 14 between an ore reducer and a melting furnace, and comprising a plunger assembly sliding closely in a waterjacketed plunger housing section 13, which has a fuel feed 29 from a hopper 30 and connects into the passage 14, the assembly comprises a cylindrical body section 28, Fig. 3, containing the rod 39 of a piston 82 disposed outside the cylinder and movable away therefrom to form therewith a fuel container. The operating means include a fixed piston assembly 11 which acts with a movable cylinder 12 and the plunger body assembly to provide a reciprocable feed action. The plunger body section 28 is joined to and separated from the cylinder 12 by a cover member 36, carrying the piston-rod 39 and being formed with a radial hole 37, opening into the fluid cylinder 12 and controlled by a valve 101. The fluid cylinder 12 is also connected to the flexible dust boot 75 of the fixed piston assembly 11 by a cover 40, and contains a piston 43 carried by the rod 39, and the piston 44 of the fixed piston assembly. The latter comprises a double tube piston-rod 60, 70 fixed to a stationary bracket 62 at one end and to piston 44 at the other. The inner tube 60 has a fluid supply port 64 controlled by a valve 102 and a fluid delivery port 66 leading into the cylinder 12. The annular space between the tubes is connected to a fluid supply port 72 controlled by valve 103 and to ports 73 behind the piston 44. The plunger body section 28 comprises two sections keyed across at one end 78, and containing at that end a guideway 80 in which slides one end wall 83 of a plunger member 81, the other end wall of which, the piston 82, forms, together with the end wall 89 of the body section, and the lateral walls 84, 85, Fig. 5, of the plunger assembly, a collapsible chamber 88 which is open at the top and bottom. Operation.-The commencement of the operating cycle is shown schematically in Fig. 9, in which 101, 102, 103 represent three-way solenoid valves, each connected to a fluid-pressure line P and an exhaust line E. Fuel from hopper 30 is conveyed in the chamber 88 positioned between body section 28 and piston 82 and passes through the body section 13 into the passage 14 where it drops out, valves 101 and 103 being connected to the exhaust line. The piston 82 is then closed up to the plunger body section 28 by pressurizing valves 101 and 102 and neutralizing valve 103. The plunger body section is then withdrawn in its closed-up state by pressurizing valve 103. Finally the body section 28 is withdrawn from the piston 82 by exhausting valve 101, leaving the assembly as in Fig. 9 again.

Title: Improvements in or relating to process for applying protective coatings to the innersurfaces of tanks and vessels
IPC: B05D7/22
Filed: 1953-02-26
Abstract: Protective coatings are applied to the inner surfaces of tanks and vessels by introducing thereinto a fluent coating composition comprising a petroleum residuum from an asphaltic crude containing a surface active agent which substantially increases the adhesivity of petroleum residua to metal surfaces, confers upon them an affinity for metal surfaces greater than that of water, and promotes water repellency of such residua, floating the coating composition on the surface of a body of water in the tank or vessel as a uniform surface layer contacting the confining surfaces thereof at its margins, and altering the surface level of the water substantially to effect substantial surface coating of the tank or vessel interior thus contacted by the coating material.  Petroleum residua cut back to a Saybolt-Furol viscosity of 25 to 50 seconds at 122 DEG F. with a liquid petroleum oil, e.g. a light lubricating distillate having a Saybolt-Universal viscosity of 100 seconds at 100 DEG F., are preferred.  The preferred surface active agent is tall oil; others mentioned include condensation products of a diamine with alkyl or alkenyl substituted succinic or succinamic acids, anhydrides or acid esters thereof as disclosed in U.S.A.  Specification 2,482,586; water insoluble polyamines obtained by hydrogenating the condensation product of an alpha-beta unsaturated aldehyde and ammonia or an amine as disclosed in U.S.A.  Specification 2,520,720; or combinations of sulphur with an oleophilic aliphatic monoamine as disclosed in U.S.A. Specification 2,478,162; the calcium salt of sulphonated liquid petroleum fractions; and long chain aliphatic nitriles, e.g. octadecane nitrile.  In an example, a ship's ballast tank is coated by pumping thereinto a mixture comprising 33.3 volumes of a 42 to 45 second Saybolt-Furol viscosity at 210 DEG F., straight run residuum produced from an asphaltic crude, cut with 63.8 volumes of a non-refined petroluem disillate having a Saybolt-Universal viscosity of 125 to 145 seconds at 100 DEG F. and mixed with 2.9 volumes of crude tall oil, the resultant mixture having a Saybolt-Furol viscosity of between 30 and 40 seconds at 122 DEG F. Water is then introduced into the bottom of the tank below the coating material, which forms a uniform layer over the upper liquid surface, its margins merging with the upstanding walls of the tank.  The introduction of water is continued until the tank is filled, when a uniform coating is formed over its inner surface.  Alternatively, the tank may be filled with water, a surface layer of the coating material introduced, and the water thereafter drained.

Title: Turbines
Inventor: CARTER ALFRED DENIS SNOWDON
IPC: F01D9/04
Filed: 1951-03-09
Abstract: 722,001. Turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 6, 1952 [March 9, 1951], No. 5775/51. Class 110 (3).  In a single-stage turbine the row, or in a multi-stage turbine the last row, of rotor blading which is of aerofoil form and substantially cambered is followed in the direction of fluid flow by an immediately adjacent row of stator blades, also of aerofoil form, which are in number a substantial proportion of the blades in the rotor row and have a low camber compared with, and not greater in chord than, the blades of the rotor row. It is stated that the presence of the stator blades reduces the secondary losses in the rotor blades and provided that the losses in these blades are not too high this will result in an increase in turbine efficiency. The invention is described with reference to a gas-turbine jet-propulsion plant having a row of nozzle blades 13, a row of rotor blades 2 and a further row of stator blades 15. In this arrangement the gases enter the blades 15 with a purely axial velocity so that these blades are of a symmetrical streamlined section and are untwisted. The chord of the blades 15 is less than that of the blades 2. In a modification the blades 15 are given a slight camber to remove any whirl velocity in the exhaust gases leaving the blades 2. The blades 15 may be used to support the exhaust cone from the turbine casing.

Title: Improvements in or relating to milling machines for copying
IPC: B23Q35/10
Filed: 1936-02-26
Abstract: 470,929. Copying milling-machines. BRISTOL AEROPLANE CO., Ltd., WHITEHEAD, F. W., and BALL, C. A. W. Feb. 26, 1936, No. 5787. Addition to 417,709. [Class 83 (iii)] In a copying milling-machine having a tracer co-operating with a pattern to limit directly the relative movement between the cutter and work, the cutter and tracer are reciprocated relatively to the work and pattern by means of a crank and connecting rod having a yielding connection so that the amplitude of reciprocation may be limited by contact of the tracer with the pattern. The work 10, Fig. 3, such as a cylinder head for an air-cooled internal - combustion engine in which the cooling fins are to be cut, is adjustably secured by bolts and slots to a table 12, and the cutter 16 is rotatably carried by a head 15 reciprocated on guides 14 by means of a connecting rod 21 and a variable throw crank 24. The crank-pin 38, Figs. 6 and 7, carries a foot 41 adjustable in a radial slot in the crank disc 24 by means of a screw 43 and the disc is driven by a shaft 25. The crank-pin is held axially by a nut 39 and washer 40 in bushes 36 mounted in a shoe 26, 27 embracing the connecting rod and held together by studs 28. Friction pads 29, 30 of fibre &c. are held in the shoe in engagement with the connecting rod, the upper pads being pressed by springs 31. In operation, the work is fed slowly and continuously towards the cutter as the latter is reciprocated by the crank, the length of the reciprocations being limited by a vertically depending tracer 19, Fig. 1 (not shown), engaging the sides of the pattern 20 secured to the work table 12, and the shoe 26, 27 slipping on the connecting rod 21 whilst the crank is completing its rotation. When the tracer has reached the bottom of the cavity in the pattern, the machine may be stopped automatically, and if the diameter of the cutter is equal to the space between the fins on the work, the latter may then be displaced vertically to allow the cutter to operate on the next adjacent space. The stroke of the crank-pin is adjusted so as to be slightly greater than the maximum width of the cavity in the pattern. The work may be reciprocated by the connecting rod 21 and the continuous feed may be applied to the cutter head. Lubricating.-The relatively sliding surfaces on the shoe 26, 27 and the connecting rod 21 are lubricated by oilers 33, Fig. 6, supplying oil through ducts 34 to felt strips 35 engaging the connecting rod. The crank-pin 38 is also lubricated by means not shown.

Title: Improvements in or relating to electron amplifier discharge devices
IPC: H01J25/04
Filed: 1937-02-26
Abstract: 478,095. Cathode-ray tubes. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. Feb. 26, 1937, No. 5850. Convention date, March 4, 1936. [Class 39 (i)] In an electron amplifier discharge device arrangement wherein an electron beam is subjected to longitudinal control, the controlled beam is projected through one or more hollow electrodes, which act as coupling-out electrodes for collecting energy contained in the density waves set up in the beam by the longitudinal control action, each of the electrodes being substantially equal to or less than #v/2c long, where #, v, c represent respectively the wavelength of the control frequency in space, the beam velocity and the velocity of light. The electron beam from a filament K is controlled by a Wehnelt cylinder Z which sets up rarefaction and compression waves in the beam. The latter in passing through the hollow electrode E induces charges thereon, and the current passing from the electrode is substantially proportional to the space charges located momentarily inside the electrode, which are again proportional to the control voltage applied to the cylinder Z. The length of the coupling-out electrode is preferably #v/2c# and there may be a number of such electrodes spaced along the beam, the distance between the middles of successive electrodes being #v/c. In a modification, two intermeshed coupling-out systems may be provided, by arranging a number of the electrodes along the beam and connecting alternate electrodes together to form two groups, so that the charges set up in one set of electrodes have opposite signs to those set up in the other set, thus producing a push-pull arrangement which can be connected to an oscillating circuit or the like.

Title: Improvements relating to the recovery of solvent mixtures used for refining or dewaxing hydrocarbon oils
IPC: C10G73/06
Filed: 1938-02-24
Abstract: <PICT:0493999/III/1> In the process of recovering solvents from raffinates or extracts obtained in the extraction or de-waxing of mineral oils with solvent mixtures, which consists in evaporating the solvents in stage evaporators and blowing out the high boiling solvent by introducing vapours of the normally gaseous low boiling solvent, as described for example in Specifications 443,491 and 453,325, the low boiling solvent vapours are derived from a cooling apparatus in which the mixture of oil and solvent is cooled by self-evaporation of the low boiling solvent.  Solvent mixtures specified are, cresol and propane, benzene and sulphur dioxide. Lubricating oil is treated in a tower 3 with benzene and sulphur dioxide from a receiver 4 passing through an expansion valve 5 to a cooler 6.  The resulting raffinate passes to condenser pressure evaporator 9 maintained at 120 DEG  C. and a low pressure evaporator 11 at 140 DEG  C.  Benzene is removed from the oil in evaporator 11 by sulphur dioxide vapours from the cooler 6 and pre-heated if desired in a heater 13.  The oil is freed from small amounts of sulphur dioxide in an evaporator 14, and is removed through a pump 16.  The sulphur dioxide is pumped off from evaporator 11 and is recompressed.  The extract drawn off from the tower 3 is similarly treated in a further series of evaporators.
