Title: Apparatus for conveying liquid metal
IPC: B22D11/14
Filed: 1974-01-03
Abstract: 1440687 Continuous casting URAL ORDENA TRUDO KRAS ZNAM POLITEKHNICHE INST IM S M KIROVA 3 Jan 1974 00318/74 Heading B3F [Also in Division F4] Molten metal is conveyed to a mould 12 (which may be straight and downwardly directed) from a vessel 1 through a movable inlet box 3, a duct 7 having two inwardly convex walls, Fig. 3, and flanked by inductors 14 for urging the metal through the duct, and an outlet box 10, there being a drive 6 for applying a force to the inlet box 3 to move it axially of the duct 7 to ensure sealing of the joint between the box and duct. The duct 7 may be assembled from separate lengths and the casting may be intermittently withdrawn from the mould 12 shown. To counteract tension in the ceramic convex side walls of the duct 7, they are compressed, by pneumatic jacks 20 (pivotally secured to the housing 15 of one pumping inductor 14) by way of a plate 18 and insulating layer 19, against a base support 17. The pumping inductors 14 are urged towards the duct 7 by drives 16. When a downwardly-directed mould is used, the metal flow under gravity may be increased or decreased by the inductors 14 for stabilization. With intermittent casting withdrawal, when upwardly casting, as shown, the pressure exerted by the top jacks 20 is changed in step with the liquid pressure in the duct passage 8. The inlet or outlet of the inlet box 3 or outlet box 10 respectively can be closed, e.g. after a batch of metal has been cast, by a transverse slide 22; it carries an electricallyinsulating bushing 24 for a flow opening. Before a cast, the refractory lining of the duct 7 may be heated by currents induced in an inserted steel sheet body by the inductor 14. It is heated at the ends by current passed by water-cooled shoes (25) to the slides 22 at their ends where the shoes, when driven, apply force to operate the slides.

Title: Improvements in or relating to the isomerisation of olefinic compounds
IPC: C07C5/25
Filed: 1961-01-04
Abstract: The isomerization of olefins is effected in the presence, as catalyst, of a complex of a feed olefin with a halide of palladium, platinum, rhodium, ruthenium or iridium in the absence of a halogenated straight chain organic acid and a phosphorus oxychloride. The complex may be formed in situ from the halide or a complex thereof containing a compound which is displaced by an olefin, e.g. palladous chloride-benzonitrile, and the olefinic feed.  The feed may be a C4-C10 mono- or poly-olefin, preferably a branched chain olefin. Reaction is effected in the liquid or gaseous phase, preferably at the boiling point of the olefin with product distilling off.  The feed should be free of water, oxygen and sulphur-containing compounds.  In the examples 4-methylpentene-1 is converted to 4-methylpentene-2 and 2-methylpentene-1 and -2 in the presence of palladous chloride or its complex with benzonitrile, cyclohexene or ethylene.

Abstract: 802,906. Gas turbine engines; axial-flow compressors. NAPIER & SON, Ltd., D. Dec. 22, 1955 [Jan. 6, 1955], No. 468/55. Classes 110 (1) and 110 (3). In a gas turbine engine of the kind comprising an axial-flow compressor, one or more combustion chambers and a turbine mounted coaxially with and driving the compressor, an air bleed passage leads inwards from the annular working passage of the compressor towards the compressor rotor axis. A duct arranged coaxially with the compressor rotor communicates with the air bleed passage and leads towards the turbine, means also being provided for delivering cooling air from the duct outwards to the turbine rotor. The air bleed passage leading inwards from the compressor working fluid passage is formed by a non-rotary structure connected to the stator of the compressor and provided with curved vanes which convert the rotational movement of the air at least partly into movement with a component towards the axis of rotation of the compressor. In the embodiment described the compressor has twelve stages, the last two stages being shown in Fig. 2 and comprising blade rows 10, 11 mounted on discs 15, 16 which are in splined engagement with the hollow turbine-compressor shaft 4. The interstage guide vanes 12 carry at their inner ends an annular wall member 21 and a second wall member 22 is secured to the member 21 by means of rivets 25. The wall 22 is provided with curved guide vanes 24, Fig. 3, so that a passage is provided between the two walls 21, 22. The rivets 25 pass through the vanes 24. Apertures 26 are also provided in the vanes 24 and walls 21, 22. Air is led from the downstream side of the guide vanes 12 through the passage between the walls 21, 22 to an annular chamber 30 formed by the rotor discs 15, 16 and thence through four radial outlets 31 into four radial conduits 32 in the hollow shaft 4. The air then enters a duct 33 mounted coaxially within the shaft 4 and flows towards the turbine being discharged through radial outlets across the turbine rotor. Some air could also flow to a balance piston and to the bearings for cooling purposes. The periphery of the disc 17 secured to the shaft 4 forms a seal with the inner wall 18 of the diffuser duct 13. Gas seals are also provided between the walls 21, 22 of the non- rotary structure and the portions 28, 29 of the rotor discs 15, 16.

Title: Improvements in and relating to stopping and restarting mechanism more particularly for kinematograph apparatus
IPC: G03B21/50
Filed: 1924-01-08
Abstract: 232,298. Kamm, L. Jan. 8, 1924. Clutches, claw ; operating clutches.-Means for stopping and restarting mechanism such as the feed mechanism of a kinematograph projector, such mechanism being driven. by a member which continues to rotate when the mechanism is stopped and having independent means for driving or starting it by hand, comprises a clutch, means for throwing the clutch out of action and holding it so, and means associated with the mechanism whereby, when the mechanism is started up by hand, the holding means is released, the clutch then re-engaging so that the mechanism is again driven by the continuously rotating member. Fig. 3 shows a pulley E driven continuously by a belt from a motor and rigidly secured to a toothed wheel driving the shutter of a kinematograph projector. The pulley E is loose on a shaft D driving the feed mechanism, and is normally clutched to it by a pin F projecting through the pulley into a slot G<1> in a disc G secured to the shaft. The pin F is connected to a rod K which extends into the shaft D and is normally pressed into it by a spring L. The pin and disc may be disengaged, for stationary projection &c., by moving a lever O so as to shift axially a rod N which is connected by a bar N<2> to the rod K. A spring-pressed arm N<4> then engages in a notch n in the rod N to hold the pin F in the disengaged position. A shaft c, Fig. 4, geared so as to rotate when the feed mechanism is hand driven, carries a substantial disc R having a conical surface R' formed with three or more, recesses loosely containing balls S. A disc U having a similar conical surface U<1> surrounding the disc R is axially movable on the shaft, and is so moved by the engagement of the balls S and the surface U<1> when the hand drive is used to restart kinematographic projection. A pin V is then moved axially to push an arm P which is secured to the shaft of the arm N<4> and lift this arm from the notch n. The spring L then causes the clutch to re-engage and the hand drive may be discontinued. The notch n may have a chamfered edge to facilitate re-engagement of the clutch. A modified ,arrangement of levers for stopping the feed mechanism is described.

Title: Methods of treating and processing animal and vegetable oils
IPC: C11B3/04
Filed: 1949-01-08
Abstract: Animal or vegetable oils are treated with an aqueous solution of an alkali salt of ethylenediamine tetra-acetic acid, with or without additional alkali hydroxide, whereby, according to the conditions: (1) the oil is freed from metallic or inorganic impurities, or (2) free fatty acids are eliminated, as well as the metallic or inorganic impurities, or (3) the oil is saponified. In treatment (1), the oil is agitated with an aqueous solution of ethylenediamine tetra-acetic acid having at least two but not more than three neutralized carboxy groups, but if the metallic or inorganic impurities in the oil are non-basic compounds, a small proportion of a basic compound, e.g. an alkaline-earth oxide, hydroxide or carbonate, may also be added.  The aqueous phase is separated from the purified oil, concentrated, and acidified to about pH 1-2 to precipitate the aminoacid for re-use. In treatment (2), the oil may be agitated with an aqueous solution of the aminoacid containing sufficient alkali hydroxide to neutralize the free fatty acids in the oil and two carboxy groups of the aminoacid.  Alternatively, sufficient alkali hydroxide solution to neutralize the free fatty acids may be added first, followed by a solution of the dialkali salt of the aminoacid or, as a further alternative, the oil may be treated with a solution of the trialkali salt of the aminoacid.  The aqueous soap solution obtained may be acidified to about pH 4.5 to precipitate the free fatty acids, and the mother liquor may then be acidified to about pH 1.2 to precipitate the aminoacid In treatment (3), the oil may be treated with a solution containing the aminoacid and sufficient caustic alkali to react with the free and combined fatty acids in the oil and with not less than two or more than three carboxy groups of the aminoacid, or alternatively the oil may be treated with a solution of the tri- or tetra-alkali salt of the aminoacid. The aqueous soap and glycerine solution obtained may be treated with brine to precipitate the soap, and the mother-liquor then concentrated until most of the sodium chloride has precipitated. The residual solution may then be acidified to about pH 1.2 to precipitate the aminoacid, whereafter glycerine is finally recovered by neutralization and distillation. In all three treatments, the proportion of aminoacid salt may be 2-10 per cent, preferably 5 per cent, of the weight of the oil, and the volume of the aqueous phase may be 50-100 per cent of that of the oil.  The treatments may be effected at atmospheric or raised temperature.  The alkali salt of the amino acid is preferably the sodium salt, but the potassium, lithium or caesium salt may also be used.
