Title: Process for the cooling and purification of hot gases containing a minor proportion of soot and prepared by partial combustion of hydrocarbons
IPC: B01D47/00
Filed: 1965-06-23
Abstract: The invention, a process for cooling and purifying hot soot-containing gases prepared by the partial oxidation of hydrocarbons, by spraying the gases with water in two separate zones in series, is similar to that claimed in Specification 826,209, but the water used in the first zone is alkaline-reacting, e.g. caustic alkali solution or ammoniacal solution may be added to it, although this is unnecessary if the gases contain substances which dissolve in water to give it an alkaline reaction.  The apparatus may be similar to that described in Specification 978,535, in which a catalytic zone for the conversion of COS is intermediate the spraying zones, or may be similar to that described in Specification 1,018,630 in which the catalytic zone is before the first spraying zone.  In both cases, a final treatment with aqueous di-isopropanolamine solution may be included to remove H2S. Scrubbing water may be recycled to both scrubbing zones separately or through both zones in series, soot being removed with oil and make-up water being provided.

Title: Improvements in apparatus for washing coals
IPC: B03B5/20
Filed: 1923-10-24
Abstract: 206,151. Wolf, P. Oct. 24, 1922, [Convention date]. Jigs.-In a coal washer of the kind in which the water pulsations are produced pneumatically, air, which acts on the surface of the water in a compartment 6, is supplied through a pipe 3 to a valve 4 moving in a casing 5 surmounted by an adjustable valve 8; the valve 4 is lifted by the air to cut off the supply and open compartment 6 to exhaust, and then falls by gravity. A profiled obturator 9 carried by the valve 4 regulates the speed of the valve. The coal is fed through a shoot 1. The heaviest impurities S on the bed of felspar F pass through an opening 23 into a chamber 18 placed across the middle of the screen compartment, and are discharged therefrom through outlets 25. Intermediate products M pass by way of passages 27 through the chamber 18 to a discharge 23<1>, 26 in communication with a chamber 19 at the end of the screen, and the lightest products C pass partly over and partly under a sill 28 and by way of side passages to discharge shoots 30. The chambers 19, 18, 6 communicate by pipes 20, 21 with a chamber 17 containing a valve connected to a float 10 in the chamber 6 and so arranged that when the movement of the water in the chamber 6 is large the chambers 19, 18 are in communication with chamber 6; when it is less, the communication ceases; and when it is least, the chambers 18, 19 are put into communication with the atmosphere, thereby ensuring automatic regulation of the apparatus according to the thickness of the accumulating layers of material. If the material to be washed is not fine, the felspar bed may be omitted. Several such apparatus may be arranged in series, and may have supplementary discharge openings for the heavy materials arranged laterally.

Title: Improvements in and relating to methods of and apparatus for purifying oil
IPC: C10M175/00
Filed: 1925-10-26
Abstract: 242,272. British Thomson-Houston Co., Ltd., (Assignees of Brunt, C. G. van). Oct. 29, 1924, [Convention date]. Recovering waste lubricants. - In the re-conditioning of oils containing finely divided. solids in suspension by treatment with an alkali silicate or other weakly basic agglomerating substance soluble in water, the mixed oil and silicate are floated on heated water in a settling tank to separate the sludge, and the cleansed oil is then freed from diluents in an evaporator, and is finally used to preheat used oil passing to the mixer. Using the apparatus shown, used crankcase oil of an internal combustion engine, is drawn through a pipe 9 by a pump 10 and forced through a pipe 11, a heat exchanger 12, and a pipe 13 to a mixer 39 into which water-glass solution is drawn from a pipe 28 by the rotation of the paddle shaft 29 formed with a helical groove G and having only a small clearance in the housing 30. The mixture passes down a pipe 15, and in a zig-zag path for about an hour over the surface of water in a tank 16 provided with baffles 35. The sludge settles out and is discharged through a pipe 45. The oil passes over a baffle 51, under a baffle 50, and through an outlet 17 and a pipe 18 to a trough 19, from which it is distributed over the surface of an evaporator 20 for the removal of diluents. The oil is then cooled by passage through the exchanger 12 and is discharged through a pipe 22. One litre of waterglass solution of 48-50‹ Be. to 50 litres of oil is suitable. 0.1 per cent of resin preferably in solution as in benzol, or of manganese or other heavymetal resinate, preferably in solution in benzol and with 0.1 per cent of stearic or other fatty acid, may be added as described in Specification 235,861. The process is preferably conducted at about 70-80‹ C., an electric heater 38 being provided in the tank 16 to maintain this temperature. Water is fed continuously to the tank 16 through a pipe 40, a pipe 44 surrounding the discharge pipe 45, and a pipe 54 opening opposite the heater 38. The discharge of sludge through the pipe 45 is regulated by moving a valve, comprising a capillary groove in the end of a shaft 47, more or less into its bearing 46. The shaft 47 is flattened beneath the tank 16 to disintegrate the sludge. The evaporator 20, as described in Specification 235,861, comprises an electric heater in a narrow flat casing having capillary ridges and grooves on the outside. The temperature varies from about 125‹ C. at the top to about 150‹ C. at the bottom. The arrangements for continuously feeding and discharging the tank 16 may be dispensed with.

Title: Improvements in or relating to means for the reproduction of sound, particularly music, from phonograms
IPC: G11B17/14
Filed: 1933-09-28
Abstract: 431,132. Reproducing recorded sound. LEVY, G. C., 40, Avenue de Clichy, Paris. Sept. 28, 1933, Nos. 26781 and 26782. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 3, 1934]. [Class 40 (ii)] Sound is reproduced from a record of any type (disc, cylinder, film, &c.) in the reverse direction to that in which it was initially recorded. Thus, in playing a gramophone record, the direction of rotation of the turntable is reversed, the record being played with the tone-arm shifted so that the pick-up is at the opposite side of the turntable spindle to that on which it is ordinarily used, while the inclination of the needle is unchanged ; or the pick-up is turned so as to reverse the inclination of the needle and the tone-arm moves on the usual side of the turntable spindle. Several devices in gramophones are described, whereby movement of the tonearm or of the pick-up from the normal to the abnormal playing position automatically reverses the direction of drive, or allows such reversal to be made. Fig. 2 shows such a device, in which reversing-gear g is controlled by a lever i operated by a cam h fixed to the tone-arm a. In an electrically-driven machine, switches for reversing the direction of drive may be controlled by the tone-arm. Alternatively, mechanical means may be provided for allowing a reyersing-lever to be actuated only when the tone-arm is in the proper position. Re-recording of an ordinary record reproduced " backwards may be effected, by using an electromagnetic or photo-electric pick-up in conjunction with an amplifier and recording-device, together with means for modifying the tone, pitch, rhythm, &c., if desired. The record thus produced is adapted for use with ordinary reproducing apparatus. The invention is stated to be applicable for use in secret telephone transmission.

Title: Multi-stage centrifugal pump
IPC: F04D15/00
Filed: 1945-10-15
Abstract: 602,408. Centrifugal pumps. DEHN, F. B. (Waterous Co.). Oct. 15, 1945, No. 26933. [Class 110 (i)] Two centrifugal pumps arranged in one casing are changed from series to parallel working by the operation of a rotary valve. The pump impellers 66, 67, Fig. 6, are arranged back-to-back on one shaft 26 driven through gears 50, 51. The shaft 26 is supported on three bearings 109, 110 and 101 and is packed by glands 93, 97. Inlet rings 87 run in wearing bushes 89. The pumps are fed from common inlets through intake passages 61, 64, Fig. 7, which shows only the passages for one pump, and they deliver to pipes 27 which communicate with common outlets. A conduit 119 connects the delivery of the further pump which is not shown to the intake passage 64 and the junction is controlled by a rotary valve 65 which in one position closes the conduit 119 and in the other shuts off the passage 64 from the pump inlet and opens the conduit 119 to that pump inlet. A non-return valve 122 is placed in the intake passage 61 and a similar valve 120 in the delivery of the further pump. When the conduit 119 is open, as shown, the pumps operate in series. The passage 61 becomes an interstage passage and the pressure in it keeps the valve 122 closed. The high pressure delivery goes to the pipes 27 and this pressure acting against the interstage pressure of the further pump keeps the valve 120 closed.

Title: Strap tensioning tools
IPC: B21F9/02
Filed: 1974-06-18
Abstract: 1468427 Strap tensioners SIGNODE CORP 18 June 1974 [18 June 1973] 26966/74 Heading F2G A strap tensioning tool comprises a main frame 12 having a nose 14, an anvil portion 15 to the rear of the nose, a gripping assembly 18 immediately above the anvil 15 being pivoted to the main frame 12 and carrying a tension handle 20, extending above the main frame, employed both to tension the strap and to transport the gripping assembly 18 from a strap loading to a strap gripping and feeding position. The strap feeding assembly and the bifurcated pivot end of the tension handle 20 are pivotally secured to the frame 12 through a shaft 44 on which is also mounted a ratchet gear 46 driven by engagement with a drive pawl 48 pivotally mounted on the tension handle 20 between the bifurcations thereof and being biased by a spring in a clockwise direction as viewed in the figure. A second shaft 52 is also provided within the strap feeding assembly 18, being parallel to the shaft 44 and passing through the main frame 12, and having mounted thereon a tension gear 54, engaging with the ratchet gear 46, and a knurled strap feed wheel 56 which co-operates with a wear plug 36 associated with the anvil 15 to grip and feed a strap inserted therebetween. The shaft 44 is biased by a spring 42 acting against the main frame 12 such that the spring resists the raising of the strap feeding assembly 18 relative to the frame 12 through a lift arm 60, pivotally secured to the frame 12 by a pin 61, comprising two arms 62 and 64, the latter of which engages an extending projection of the strap feeding assembly 18 and the former engaging the underside of tension handle 20. In order to prevent reversal of the rotation of the wheels 56 and 54 when the tension handle 20 is released holding pawls 72 and 74 are carried within the drive section 38 of the strap feeding assembly 18 to engage the gear 54 being biased by a coil spring and being placed such that only one holding pawl is in engagement at any one time. The force required at the surface 66 transmitted through the lever 60 from the tension handle 20 to lift the strap feeding assembly 18 relative to the anvil is required to overcome the moment of the strap tension about the shaft 44 and thus, due to the disparity in moment arms between on the one hand the force exerted by tension handle 20 on the lever arm 62 about pivot 61 and on the other hand the strap tension about shaft 44, the operator should therefore find it difficult to accidentally raise the strap feeding assembly 18 releasing the strap by overshooting the tension stroke and contacting the lever arm 62 with the tension handle 20 while the strap is in tension.
