Title: Improvements in or relating to purification of hydrocarbon oils
IPC: C10G33/02
Filed: 1952-03-07
Abstract: Oil- and water-insoluble contaminants are removed from hydrocarbon oils, particularly hydrocarbon oils to be used as feed stocks for catalytic cracking processes, by intimately mixing the hydrocarbon oil with water to form an initial emulsion of the oil with the water, forming from this initial emulsion a minor unbroken emulsion phase and a major free oil phase, and separating this unbroken emulsion phase as a whole from the free oil phase. The contaminants which may be iron, its oxides and sulphides, other metal compounds, carbon, siliceous materials and heavy hydrocarbonaceous materials such as pitches and asphalts, become concentrated in the minor unbroken emulsion phase, which may be treated, for example by processes involving filtration or distillation, to obtain uncontaminated oil therefrom. Alternatively, this minor unbroken emulsion phase may be broken, for example by long time gravity settling, treatment with caustic alkali or other chemical emulsifiers, or by electrical precipitation, and the contaminated oil obtained may be distilled or it may be recycled by mixing with the hydrocarbon feed oil from which the initial emulsion is formed.  The hydrocarbon oil to be purified may be a gas oil, a lubricating oil, a cutting oil or an oil for oil burners.  In preparing the initial emulsion, the oil and water may be intimately mixed at elevated temperature and pressure in a mixing valve to produce a water-in-oil emulsion. The initial emulsion may be converted into a minor unbroken emulsion phase and a major free oil phase by gravity settling, but the conversion may be facilitated by the addition of emulsion breaking agents such as petroleum sulphonates, or by filtering, centrifuging or applying electrical precipitation.  Suitable conditions under which the purified oil may be catalytically cracked are described.  The process of Specification 680,244, for breaking an emulsion, is disclaimed.

Title: Improvements relating to shearing machines for removing loose fibres from yarn, cordor twine
Inventor: MACKIE JOHN PRINGLE
IPC: D06C13/00
Filed: 1955-03-03
Abstract: 801,342. Smoothing cord &c. MACKIE & SONS, Ltd., J. Feb. 10, 1956 [March 3, 1955], No. 6328/55. Class 109 [Also in Group IX] In a shearing machine of the form described in Specification 403,038, Fig. 1 (not shown), for removing loose protruding fibres from a cord or twine of long fibres e.g. flax, hemp, jute, sisal or manilla, and in which the cord is passed along the length of rotary spiral cutting blades and then passes through a false twist device which causes the cord to rotate about its longitudinal axis as it passes the blades so that the cord is sheared evenly around its periphery, the motion of the false twist device is derived from the motion of the cord itself: immediately movement of the cord ceases the drive to the false twist device is interrupted and the danger of snarling in the cord is avoided. In a modification of the earlier machine and as shown in Fig. 2, cord leaving a false twist device 15 comprising rollers 16, 17, 18, passes around the lowermost groove of a driven haul pulley 19 and then around the lowermost groove of an idler pulley 20, thence around a pulley 45 on the shaft of the device 15 (which is driven thereby) returning to the second groove from the bottom of the pulley 20 and from there to the third groove from the bottom of the pulley 19. In an alternative driving arrangement, Fig. 3, cord leaving the device 15 is passed backwards and forwards around successive grooves in the pulleys 19 and 20 finally leaving the top groove of the pulley 19 to pass to a guide and a wind-up bobbin (not shown): the idler pulley 20 is provided at its base with an additional groove which accommodates a flexible belt 46 passing around (and thus transferring any motion of the pulley 20 to) the pulley 45. In each apparatus stoppage of the pulley 19, and hence of the movement of the cord, causes the cord to slacken and the pulleys 20 and 45 to cease rotating.

Patent GB-734879-A (GB)
Title: Manufacture of 6-acyl-2-naphthols
Filed: 1953-03-10
Abstract: 6-Acyl-2-naphthols are manufactured by acylating a 2-hydroxy-1-naphthoic acid or a 2-naphthol-1-sulphonic acid with an organic acid chloride or anhydride in the presence of a Friedel-Crafts catalyst, and heating the acylation product in the presence of an aqueous mineral acid to split off the carboxyl or sulphonic acid group.  Instead of a pure 2-naphthol-1-sulphonic acid there may be used as starting material a crude sulphonation mixture obtained by treating 2-naphthol with chlorsulphonic acid in a solvent suitable for the subsequent acylation.  In examples: (1) 2-naphthol is sulphonated with chlorsulphonic acid in nitrobenzene, the reaction mixture is added to the addition product formed by introducing aluminium chloride and acetyl chloride into nitrobenzene, and the acylation product is isolated and heated with dilute sulphuric acid to produce 6-acetyl-2-naphthol; (2) 2-hydroxy-3-naphthoic acid is sulphonated with chlorsulphonic acid in dichlorethane in the presence of aluminium chloride, and the product is treated as in (1) (but using dichlorethane again as solvent in the acylation step) to give 6-acetyl-2-hydroxy-3-naphthoic acid; (3) 2-hydroxy-1-naphthoic acid is treated with succinic anhydride in dichlorethane in the presence of aluminium chloride, and the product is heated with dilute sulphuric acid to form 6-succinyl-2-naphthol; (4) the same product is obtained similarly from the mixture obtained by sulphonating 2-naphthol as in (3).

Filed: 1936-03-05
Abstract: 453,475. Revolving creels for gilling, doubling, drafting, and like machines. SMITH, W. PRINCE-, Hillbrook, Keighley, and AMBLER, G. H., Dumb Mills, Frizinghall, Bradford, both in Yorkshire. March 5, 1936, No. 6678. [Class 120 (ii)] In a revolving creel for use with gilling, doubling, drafting, and like machines each of the individual driving rollers C serving to rotate the balls of sliver is fitted with a stopmotion the action of which is controlled by the amount of the sliver extending from the corresponding ball to the machine. Each ball A is supported on fluted rollers B, C, Figs. 1 and 2, mounted respectively on shafts B<1>, C<1> each roller C being driven and each roller B being an idler. The roller C is provided with an end flange 1 projecting from a housing 2 having walls 3, 4 and enclosing a shouldered sleeve 5 integral with a boss 6 secured to the shaft C<1> by a set screw 7, Fig. 3, the boss 6 serving as the driver for the roller C by contact of one of three lugs 6A, 6B, 6C thereon with a lug 9A on a latch member 9 which is pivotally mounted on a pin 8 supported by bearing flanges 2A. The lug 9A on the latch 9 is projected forwardly into a slot 4A in the wall 4 by a spring 11, Fig. 4. A face cam 14 having a working surface 14A and formed with a tail-piece 14B is pivoted at 13 and a duplicate cam (not shown), is provided at 15. A collar 17 having a segmental slot 17A is secured on a stationary rod 16 a rocking arm or detent 18 being loose thereon and having a segmental projection or lug 18B narrower than the slot 17A, Fig. 6. A feeler is provided comprising a rod 21 supported on wires 20 projecting from collars 19 loose on the rod 16 and a bifurcated tappet comprising two curved fingers 22, 23 integral with the boss 19B of collar 19 is arranged to embrace the detent 18. When the sliver is being delivered normally to the machine it occupies the path S<1>, Fig. 2, and supports the rod 21 as shown dotted. When supplied in excess of demand it occupies the path S<2> and the rod 21 and wires 20 move angularly down to operate the stop-motion and stop the rotation of roller C which remains stationary till the slack is taken up and the sliver drawn back to the position S<1>. Lowering of the rod 21 moves the collars 19 angularly on the rod 16 until the tappet finger 22 engages the detent 18 and moves it angularly until the lug 18B reaches the end of the slot 17A. Then the nose of the detent 18 engages the member 14B and rocks the cam 14 so that the face 14A moves the latch member 9 until the lug 9A is withdrawn from the lug 6A, 6B, or 6C with which it is in contact thereby stopping the drive. As the sliver is used and returns to the position S<1> reverse angular movement of the collars 19 brings the tappet finger 23 into contact with the detent 18 removing its toe from the tail piece 14B of the cam 14 and permitting the spring 11 to force the latch 9 forward until the lug 9A again projects through the slot 4A and engages one of the lugs 6A, 6B, 6C.

Title: Improvements in or relating to apparatus for measuring blood pressure
IPC: A61B5/022
Filed: 1938-03-04
Abstract: 494,815. Blood-pressure measuring- apparatus. SIEMENS & HALSKE AKT.- GES. March 4, 1938, No. 6875. Convention date, March 12, 1937. [Class 81 (ii)] In apparatus for continuously measuring blood-pressure in which compressed air is fed to an inflatable sleeve through a pipe which also communicates with a closed chamber, there is provided in the chamber a bolometer arrangement which is influenced by the air pulses set up by the pulse beat, and regulates through an amplifier the supply of air. A sleeve comprising two cushions o, u, secured about the upper arm of the patient, is inflated by air from a pressure vessel 2 through valves 3, 5, 6 and an electromagnetically-controlled valve 4. Quick-filling and quick-discharge valves 11, 12 are also provided. The sleeve communicates through slot-nozzle 8 with a chamber 9 containing a bolometer bridge 15, 16, 17, 18 which is fed from transformer 20. For the measurement of the systolic blood pressure, the pressure within the sleeve, which is first greater than the systolic pressure, gradually drops due to escape of air from chamber 9 through valve 7 and relief valve 10, until at about the systolic blood pressure, a pulse beat causes a jet of air to be ejected through slot 8 on to the branches 15, 16 of the bolometer bridge which are thereby cooled. The potential disturbance in the bolometer bridge is amplified in amplifier 21 and causes the electromagnetically-operated valve 4 to open. This is kept open by a retarding arrangement in the amplifier until the bolometer reaches its equilibrium state, whereupon the cycle is repeated. The pressure fluctuations are indicated by manometer 14 and recorded by pressure recorder 13, the systolic blood pressure being shown by the lower peaks of the curve. An oscillograph 24 may be connected to the output terminals of the bolometer bridge through amplifier 23. For measurement of the diastolic blood pressure, the valve 4 is normally open, the pressure gradually increasing until a pulse beat causes a sufficiently large air impulse to operate the bolometer thereby causing the valve 4 to close. The valve remains closed for a predetermined period during which the pressure drops, due to the escape of air through valve 10, below the value at which the apparatus is sensitive to pulse beats. The valve 4 then opens again and the cycle is repeated. The upper peaks of the curve correspond to the diastolic blood pressure.
