Title: Method of separating a complex fluid stream into its component parts
IPC: B01D3/00
Filed: 1937-05-14
Abstract: 500,942. Centrifugal separation; fractional condensation. LOUMIET ET LAVIGNE, J. May 14, 1937, No. 653/39. Convention date, May 14, 1936. Divided out of 499,024. [Class 23] [Also in Group III] A complex fluid stream is separated into component parts, during its passage at high velocity in a helical path, and while the centrifugal and gravitational forces are effecting the separation the temperature conditions tend to condense the denser component, and to evaporate any condensed portion of the lighter component. An arrangement suitable for the separation of water and alcohol is shown in Fig. 1. The tanks V<1>, V<11> contain helical coils for the passage of the fluid ; the entry part T is of circular section and this merges into the uppermost of the helical convolutions which have a cross-sectional area equal to that of the part T but are broadened in the direction of the resultant separating force. The upper part 101 of the coil in the tank V<1> acts as a separating coil as described in Specification 499,024 and the resultant stream is led to the lower coil 102. Injections of the original fluid are made through the supply pipe M to a central zone in each convolution of the coil 102 as described in Specification 499,024 and after the rectification achieved in this coil watery liquid is extracted by the pipes E while alcohol vapours pass through pipes to the cylinder F which is constructed round a central well W, and thence by the pipe E<4> to the cylinder Fx in the second tank V<11>. The fluid under treatment passes from the coil 102 to the coil 102a in the tank V<11>. From this it passes to the lower coil 103, which is of the general form described in Specification 490,703 and is for the purpose of condensing the alcohol vapours so that the condensate can be extracted by the pipes R. The cooling liquid enters the tank V<11> by the pipe K and passes upwards to the pipe K<1> which leads it to the tank V<1>, where the top convolution of the coil 101 is cooled only by vapour and not by the liquid. The convolutions of the coils are formed with flange like extensions 105, Fig. 3, and the heating effect caused by friction evaporates the more volatile part of the fluid. If desired this flange can be cooled by a jacket 107. A number of such flanges may be used where internal partitions are used as shown in Fig. 5.

Title: Method of Processing Fly Dusts Containing Sulphur, and Smelter mixed Oxides or other mixed Oxides Containing Zinc and Lead
IPC: C22B7/02
Filed: 1968-01-04
Abstract: 1,173,251. Extracting metals. UNTERHARZER BERG-und HUTTENWERKE G.m.b.H. Jan. 4, 1968 [Feb. 2, 1967], No.589/68. Heading C7D. Fly dusts, smelter mixed oxides and/or other mixed oxides containing sulphur, zinc and lead are processed to give a crude lead, a slag rich in zinc and sulphur and a secondary fly dust which can be sintered, by mixing them with barium sulphate and excess reducing agent (e.g. coke) and melting the mixture in a furnace at 820‹ -1000‹ C. The process may be carried out in a rotary tube furnace supplied with a counter-current flow of combustion air at 200‹ -300‹C. using, as the source of barium sulphate, barytes or a lead-zinc ore containing barium sulphate. The crude lead is preferably tapped in the presence of air so that zinc can evaporate therefrom and be oxidized: further zinc may be removed by tapping the lead into a pot containing solid lead so that the molten lead cools whereupon zinc dross forms on its surface, this dross being removed and purer lead being tapped from the bottom of the pot.

Title: Improvements in or relating to ionization gauges suitable for leak detection in evacuated systems
IPC: H01J41/04
Filed: 1946-01-07
Abstract: 619,133. Determining physical qualities of materials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 7, 1946, No. 622. Convention date, Jan. 31, 1945. [Class 37] [Also in Groups XIX and XL (a)] Apparatus for detecting a leak in an evacuated device comprises a thin metal window permeable only to hydrogen, means for subjecting one side of the window to the pressure in the device, the other side of the window being maintained at a pressure lower than the pressure in the device, means for bathing the exterior of the device in an atmosphere rich in hydrogen, and means for measuring the amount of hydrogen which passes from the interior of the device through the window. As shown, an ionization gauge comprising a sealed glass vessel 1 enclosing a cathode, grid, collector, and a barium berylliate getter, has an extension compartment 6 with an outlet 7 for connection to the evacuated device. Within the compartment 6 and sealed into the vessel 1 is a window 8 of palladium or other material permeable only to hydrogen and heated by a tungsten or molybdenum coil 9 connected to a battery &c. The outlet 7 is connected through a liquid air trap 12 to an exhaust system 13, provided with stop cocks 14, 15, and to the evacuated device 17 such as a radio valve. The'valve 17 may be surrounded by a hydrogen hood 18, or it may be probed for leaks by a jet of hydrogen, any hydrogen entering the valve passing through the system into the gauge which registers a corresponding rise in pressure. Traces of hydrogen may be introduced into the system to remove any oxide film formed on the window 8 by including in the system a palladium thimble 20, surrounded by a heating coil 21, to which the hydrogen can be supplied ; or hydrogen may be generated by a tungsten filament 19 exposed to the interior of the system and heated to about 900‹ C. to decompose oil vapours present in the system from the pump. Any hydrocarbon vapours in the system are prevented from reaching the window 8 by the trap 12.

Title: Improvements in and relating to combined service and safety brakes for shaft elevators
IPC: B66D5/26
Filed: 1937-01-08
Abstract: 466,407. Fluid - pressure brakes. SHEVLIN, J. T. (Siemens-Schuckertwerke Akt.-Ges.) Jan. 8, 1937, No. 660. [Class 103 (i)] In a brake system for shaft elevators of the kind in which the normal or service brake is actuated by the admission of compressed air or steam to an operating cylinder and is combined with a safety brake operated by means of a weight, the service brake cylinder 5 and piston 6 are movably interposed in the link system between the safety weight 13 and the brake blocks 2 so that, when the safety braking means become operative, both the cylinder 5 and the piston 6 are displaced. In the arrangement shown in Fig. 1, the piston 6 is operated to apply the brakes by admitting compressed air to the cylinder 5 from a container 18 via a valve 19 and flexible piping 31, while the weight 13 is normally maintained in a raised position by admitting pressure to a cylinder 14 through a pipe 20 and control valve 21. The rods 8, 30 which actuate the valves 19, 21 are connected to a common differential lever which permits the valve 19 alone to be actuated, or in the case of emergency, both valves 19, 21. In the latter case, the cylinder 5 and piston, being mounted on the end of a pivoted lever 10 of the safety brake mechanism, move upwardly to apply the brakes to the drum 1. In a modification, Fig. 2 (not shown), the service cylinder 5 is mounted upon the piston of the safety brake cylinder, this piston in turn being carried upon the end of the lever 10. In another construction, Fig. 3, the service brake cylinder 52 is formed as part of the piston 43 of the safety brake, which is controlled by a weight 44. The pistons 43, 53 are additionally controlled by the admission of fluid pressure through ducts 49, 56 under the control of service and safety brake levers 60, 75 coacting with a differential lever 69. A safety release magnet 64 is also incorporated. The pressure in the annular space 50 surrounding the cylinder 52 may be maintained by the closing of an adjustable throttle valve 72, the position of which may depend upon the pressure in the fluid supply pipe 62.

Title: Process and apparatus for the dry mechanical extraction of fibres from the stems of textile plants
IPC: D01B9/00
Filed: 1951-01-12
Abstract: 699,521. Preparing fibres for spinning. ANGIOLINI, A., and BARBUTI, R. Jan 12, 1951 [Jan. 12, 1950], No. 959/51. Class 120(i) Fibres are freed from plant stems, from the wood or straw tissues, from incrusting substances and from internal surrounding tissues, without previous treatment of the stems and in dry state, by feeding them, while disposed in a layer, perpendicularly to a plurality of operating cylinders whereby they are rolled, broken, scutched, shaken, cleaned and softened or further scutched, and brushed, the scutching being effected by cylinders provided with teeth engageable with each other and with a gap therebetween and rotating at a peripheral speed greater than the advancing speed of the fibres. As shown, Fig. 1, stems 1 are fed longitudinally between cylinders 5, 5<SP>1</SP>, 6, 6<SP>1</SP> and 31, 31<SP>1</SP> which have progressively increasing peripheral speeds and which roll and stretch the stems. Between the pairs of cylinders the stems are supported on inclined planes 7, 8. From cylinders 31, 31<SP>1</SP> the stems pass between pairs of toothed breaking cylinders 9 which rotate at the same peripheral speed as cylinders 31, 31<SP>1</SP>. The thickness of the teeth of cylinders 9 at the pitch line is preferably not greater than a quarter of the distance between the ends of the teeth which is equal to the length of each tooth. Means is provided for adusting the engagement of the teeth. The stems are fed by cylinder 9 to a group 10 of cylinders, Fig. 3, comprising feed and delivery cylinders 11, 13, covered with resilient material, and scutching cylinders 12, similar to cylinders 9 but rotating at a speed greater than that of. the stem material. Additional toothed cylinders 16 are provided for treating the terminal portion of the stems after they have left cylinders 12. Cylinders 13 rotate slightly slower than cylinders 11 so as not to tension the fibres. From the scutching cylinders the fibres fall on to a lattice conveyer 17 which is vibrated by a device 20 to cause woody residues to fall on to an inclined' plane 21. The fibres then pass to a series of cylinders 22 having lengthwise grooves, or to one or more pairs of scutching cylinders to group 10; in either case the last pair of cylinders has circumferential grooves to subdivide the ribbon of fibres into bundles. The fibres are then brushed by cylindrical hair or wire brushes 12, two resilient metal strips 26 engaging the brushes to assist in brushing the rear part of the fibres. Brushes 23 operate in a casing 27 connected to a waste-removing exhauster. For treating short fibres, a further pair of stretching cylinders 29 stretches the fibres as delivered from the brushing treatment by cylinders 25. The ribbon of fibres. issuing from cylinders 29 is removed by a belt 30.

Title: Laminated creped tissue products and the manufacture thereof
IPC: D21H27/40
Filed: 1971-01-11
Abstract: 1344541 Laminate CANADIAN INTERNATIONAL PAPER CO 11 Jan 1971 [12 Jan 1970] 961/71 Heading B5N A laminate suitable for use as towelling comprises a pair of creped tissue webs, each having a basis weight of 9 to 16 lbs. per ream and a crepe ratio of between 1À2 and 1À5 and each having substantially parallel lines of creping and having portions of the surface raised with respect to other portions, said webs being superposed with their lines of creping parallel and being bonded by an adhesive disposed between the web in a pattern which leaves substantial unbounded regions while each web being in a different condition of stress in the plane of the web perpendicular to the lines of creping the raised portions on each web opposing those on the other. The webs are preferably embossed prior to bonding. The adhesive, e.g. polyvinyl alcohol, may be in aligned spots, which may be smaller in regions of greater concentration of spots, and which may form a guilt pattern. The laminate may be made by drawing tissue webs 10, 9 over tensioning rolls 15, 16 and thence into respective nips of embossing rolls 12 and 13, 18 and 19. The adhesive is applied in a pattern to web 10 from roller 24 having rubber impression mat 27 on its surface and the webs are then bonded in the nip of rolls 28, 30, the latter carrying a mat 31 corresponding to that on roll 24 so that pressure is restricted to the adhesive areas. The speeds of the unwind stands 5, 6 embossing rolls 12, 13, 18, 19 and laminating rolls 28, 30 are adjusted in order that the webs are united at different tensions. After lamination the tension is relaxed so that one of the webs has a greater area than the other in the unbonded region and thus buckles and improves the hand of the product. The thickness of the laminate is such that 130 sheets each 10 inches long produce a roll 5¥ inches in diameter when wound on a 1¢ inch diameter core.

Filed: 1938-01-12
Abstract: 507,672. Vehicle bodies. CAMPBELL, J. Jan. 12, 1938, No. 966. [Classes 103(iv) and 108 (i)] An upper deck of a plural-deck road or rail vehicle adapted, e.g. for the transport of livestock, is made in sections including a verticallymovable intermediate section 16 lying opposite a door on one side or between oppositelydisposed side doors and capable of being raised from an operative position into an inoperative position near the vehicle roof. As shown, the upper deck comprises two end sections 12, Fig. 1, each mounted to swing into a horizontal or a vertical position about a shaft 13 adapted to roll on tracks 15. The middle section 16 normally rests on the ends of the sections 12 when horizontal or on other supports and is suspended at each corner on cables or ropes 17 passing over pulleys 18, the two ropes 17 at each side being spliced together to one of a pair of ropes 19 which pass over pulleys 20 to drums 21 oil a winding-shaft 22 by means of which the middle section can be raised, counterbalance weights 31, Fig. 2 being connected by four cables 29 passing over pulleys 30 to the corners of the section to enable the section to be raised without undue manual effort. Alternatively, either the weights or the winding apparatus may be dispensed with. Beneath the middle section a loading ramp is stowed comprising a floor 32, Fig. 4, having cross-spars 32a and collapsable sides 33, rollers 34 at the corners of the floor being adapted to run on a pair of transverse runners 35 secured to the underside of the section 16. As the ramp is drawn out at either side of the vehicle and lowered into either of the inclined positions shown in Fig. 5 it rests upon one of a pair of horizontal bars or rollers 36, Fig. 4, movable vertically between guides 37 on each door post 11 and suspended from the cables 29 so that the ramp on being slid out is also counterbalanced by the weights 31 which normally pull the bars 36 against the underside of the ramp. Alternatively the ramp may he counterbalanced by means separate from the means for counterbalancing the middle section. A pivoted stop on the section, 16 permits the front pair of rollers 34 on the ramp to be drawn off the runners 35 and obstructs the rear rollers. To allow the ramp to be moved into the full-line position shown in Fig. 5 the middle section is formed with an H-shaped frame 42, Fig. 6, having its two open portions lying opposite the side doorways, and covered by n pair of hinged floor sections 43 which when open permit the upper end of the inclined ramp to be brought close to the cross-bar 44 of the frame 42. If the vehicle has only one side door, the flooring 43 at the opposite side may be permanently fixed to the frame. A spring- pressed catch holds the middle section in its inoperative position' near the roof. Specification 397,110 is referred to.

Filed: 1987-01-06
Abstract: PURPOSE:To prevent exertion of the compressive stress of the coating layer itself on an article by forming a protective coating of >=2 layers consisting of an inside layer and outside layer having the Young's modulus higher than the Young's modulus of the inside layer and providing a stress relieving layer between the article and the inside layer. CONSTITUTION:The protective coating layer of a glass fiber 1 consists of the inside layer 2, the outside layer 3 having the Young's modulus higher than the Young's modulus of the inside layer and high strength, and the stress relieving layer 4 provided between the optical fiber 1 and the inside layer 2. The material to be used as the soft inside layer is exemplified by thermosetting silicone rubber, thermoplastic rubber, etc., and the material to be used as the hard outside layer having the Young's modulus higher than the Young's modulus of the inside layer is exemplified by the resins similar to the resins for the inside layer, material which is increased in the Young's modulus in compsn., thermoplastic resins, etc. The stress relieving layer is provided between the article to be protected by the coating and the inside layer and may be provided with a gap. The direct transmission of the working strain of the cladding and the compressive stress to the object (fiber) is thereby obviated.
