Title: Improvements in or relating to a process of and apparatus for the distillation and gasification of solid carbonaceous material
IPC: C10B49/06
Filed: 1928-07-07
Abstract: 322,765. Karrick, L. C. July 7, 1928. Coking processes; producers.- Carbonaceous material such as coal is passed in the form of powder together with steam through a heated conduit, the solid residue separated, and the hot vapours and gases used to generate a further supply of steam which may be used to gasify more powdered fuel from which the hot gases are again employed to carbonize lump coal by direct contact therewith, coke, resins oils and gas being recovered. Pulverized fuel from a, hopper 13 in which it is preheated, is fed by a conveyer 17 to a pipe 4 together with steam under pressure through a valve 6, the pipe being heated by burners 11 to between 700‹ and 1200‹ F., when low temperature distillation is effected, but from 1350‹ to 1850‹ F. when water gas is required. Pieces of metal fed from a hopper 20 serve to scour the inside of the pipe 4. The gases are separated from the ash and coke in a cyclone separator 23 and pass through a cooling coil 27 to a vessel 29 in which resinous substances, tar acids, ammonia, water, gases and oil, are separated. Steam generated in the cooler 26 is used for the complete gasification of powdered fuel in a coil 38 functioning in a manner similar to pipe 4, the solid residue being removed in a cyclone separator 49. The hot gases at 1200‹ to 1850‹ F. are led by pipe 51 to a retort 53 in which lump coal is carbonized by direct contact with the gases, which enter either through inlets 56 or 58 and leave through outlets 60 or 85, passing through a cyclone separator 61 to a condenser 63 and bye-product separator 64. The coal may be preheated by the passage through it of hot gases in a hopper 55, these gases passing downwards and preventing distillates from below entering the hopper. Steam from a main 81 may be heated by being passed by pipes 78, 79 through the hot coke and through the charge above, and this steam supply may also be used to preheat the fuel in the hopper by admission through a pipe 87. This steam supplied to the coke may contain salts such as sodium nitrate, sodium chlorate or a halogen salt or odoriferous materials such as oil of pine or cedar so as to impregnate the coke discharged.

Title: Apparatus for feeding a flattened tubular web or tube of flexible material
IPC: B65H20/04
Filed: 1963-05-20
Abstract: 961,116. Feeding webs. FR. HESSER, MASCHINENFABRIK A.G. May 20, 1963 [July 17, 1962], No. 19878/63. Heading B6B. Relates to apparatus for feeding (continuously or intermittently) flattened tubular material in which the web is in contact with a feed drum 5 over a predetermined arc defined by guide rollers 4, 6. According to the invention, slip between the two plies of the web as it passes round the drum is prevented by grippers 15 which rotate with the drum and are moved into and out of gripping position by cam mechanism at the points where the web meets and leaves the drum. The drum is driven selectively by two chain drives having different ratios; normally the slower drive is operative. The outgoing web passes over a biased roller 8 to form a loop. If a tension increase shortens the loop, a switch 36 is actuated to throw in the faster drive until the tension has been reduced. The surfaces of the drum and grippers have rubber layers to increase friction.

A reusable tube coupling comprises a sleeve 12 has grooves 22 into which a tube 10 is swaged 10 prior to making the coupling by swaging a union member 16 having a tapered mouth 32 adapted to sealingly coact with a tapered end portion 34 of the sleeve, and an externally-threaded nut 14 having an internal flange providing a side face 42 which is adapted to abut a side face 40 of an intermediate enlarged sleeve portion causing the tapered end portion 34 of the sleeve to sealingly engage the mouth of the union member and be inwardly and elastically deflected thereby until the other side face 38 of the enlarged sleeve portion engages the end face of the union member to limit further tightening of the nut. The said enlarged sleeve portion is recessed at 44 to facilitate slight elastic deformation of the sleeve part 41 by the nut to prevent slackening of the nut by vibration The nut and sleeve side faces 42 and 40 are inclined at 45 and 55 degrees respectively prior to tightening the coupling and the mouth preferably tapers at an angle of 12 degrees. Another tube 18 is swaged into annular grooves 17 formed in bore of said union. In a modification, Fig. 6 (not shown), a tube is held in the other end of the union by a sleeve in the manner described above.
Patent GB-147875-A (GB)
Title: Improvements in and relating to the letter width spacing mechanism in typewriters
IPC: B41J19/32
Filed: 1920-07-09
Abstract: 147,875. Wanderer - Werke vorm. Winklhofer & Jaenicke Akt.-Ges. Oct. 2, 1914, [Convention date]. Letter-spacing mechanism.-In differential escapement-mechanism of the kind in which the loose dog is associated with a stop which is adapted to permit of a single-space or a double-space movement, the universal bar for the dogrocker is operated by all the type-levers, and the stop is withdrawn to permit of the double-space movement by means of a universal bar operated by the key-levers that are associated with double-width types; the arrangement ensures the withdrawal of the stop before the dog-rocker is operated. In the arrangement shown in Figs. 1 and 4, the type-levers actuate a universal bar 33 connected to rock arms 36 of which one abuts on a rocker 2 provided with fast and loose dogs 3, 7. Normally, a tooth 6 on the loose dog engages the escapement wheel 1, and the loose dog abuts on a stop 10. When released, the loose dog is rocked by a spring 9 until the tail 8 is arrested by an adjustable stop 13 which is pivoted on the rocker and is controlled in the following manner. The key-levers 29 associated with double-width types are provided with lugs 31 for actuating a universal bar 30 carried by arms 26 which are connected by a yielding link 27, 28 to a lever 21 engaging a roller 18 on the stop 13. Normally, a spring 14 retains a pin 16 on the stop 13 in contact with the end of a slot 15 in the rocker, and the stop is positioned for permitting of a single-space movement of the loose dog. When, however, the double-width keys are operated, the stop 13 is rocked into a positi in for permitting of a double-space movement of the loose dog. Thereupon, the rocker releases the tooth 6, the loose dog swings until arrested by the stop 13, and, upon return of the rocker, a tooth 5 on the loose dog engages the escapement wheel, as shown in Fig. 4, and the escapement wheel describes a double-space movement which is arrested by the engagement of the loose dog with the stop 10. The movement of the lever 21 is limited by a stop 24. Fig. 1, further movement of the universal bar 30 being permitted the yielding link 27, 28. The screw for securing the fast dog 3 may be employed for the stop 10, the head of the screw being employed to guide the tooth-part 5. To provide for uniform double-spacing, the universal bar 30 can be retained in the depressed position by means of a crank 38, Fig. 1.
Patent GB-404346-A (GB)
Title: Improvements in the manufacture of artificial filaments, threads, ribbons, films andother artificial products
IPC: C08L1/00
Filed: 1932-07-14
Abstract: The process described in the parent Specification according to which the lustre of artificial filaments, yarns, films, &c. is reduced by incorporating therein insoluble organic fibrous material, including regenerated cellulose and cellulose derivatives, in a finely divided state, is modified either by the employment of an organic fibrous material reduced to a fine state of subdivision by precipitation in a liquid medium, or by the use of finely divided cellulose benzoates in particular dibenzoyl cellulose as the delustring agent. The cellulosic material to be afterwards precipitated, may be dissolved in sulphuric acid, zinc chloride, thiocyanates, cuprammonia solution etc.; or it may be converted into viscose and subsequently precipitated from such solution. Precipitation may be effected by heat, by chemical action, or by dilution as with water and other non-solvents; thus, from a zinc chloride solution, cellulose may be precipitated by water, dilute acids, alcohol &c., from cuprammonia solution by salts, acids, alkalies, sugar &c., from viscose by acid reagents, and from a solution of dibenzoyl cellulose, the latter may be precipitated by a non-solvent such as a hydrocarbon or ether. Any residues of zinc in the cellulose precipitated from zinc chloride solution may be removed by dilute acids, and similarly copper may be removed from the cellulose obtained from cuprammonia solutions. The necessary subdivision of the cellulose or cellulose derivative during the process of precipitation may be effected by agitation or stirring as by mechanical means or by means of liquid jets or by introducing a gaseous precipitating agent through spray nozzles; and precipitation may be carried out in the presence of dispersing agents such as organic sulphonic acids, gelatine, glue &c. In examples, a solution of cellulose in sulphuric acid is diluted with water to the point of precipitation whereupon it is projected as a spray into sodium sulphate solution under vigorous agitation producing a cellulose suspension which is subsequently dialysed and then transferred to acetone for addition to a cellulose acetate spinning solution; a solution of dibenzoyl cellulose is sprayed into an excess of alcohol, and the resulting finely divided product incorporated in a viscose spinning solution.

Title: Improvements in textile winding machines
IPC: B65H54/74
Filed: 1956-06-29
Abstract: 819,662. Winding yarns. HOLT Ltd., T., and BRIERLEY, E. Sept. 30, 1957 [June 29, 1956], No. 20123/56. Class 120(2) A winding machine includes a pivotally- or slidably mounted package holder, a traverse cam and reciprocating thread guide, means for rotating the package holder and traverse cam and means for regulating the movement of the package with increasing diameter by using the rotation of the package to drive a lightly loaded wheel or rol- 1er which in turn transmits motion to mechanism to move the package as it builds up by positively moving out the package at a predetermined rate and at the same time progressively decreases the package spindle and traverse speeds in correspondence. In the arrangement shown the spindle 10 on which the yarn package 16 is wound is driven from shaft 23 through friction discs 21, 20, the former being integral with a boss 22 slidable on the shaft 23, and pairs of stopped pulleys 18, 17 reciprocated by a traverse cam housed in box 25 and rotated by shaft 26 driven from the shaft 14 through coned pulleys 28, 27 and belt 29. The latter is adapted to be shifted along the pulleys by a bell shifter wrapped by belt 19. Thread guide 31 is 30. A roller 32 is freely mounted at opposite ends in a pair of pivotally mounted bell-cranked levers 33, 34 each Weighted so as to keep the roller 32 in contact with the package 16. In operation, when the diameter of the package 16 reaches a cer- .tain point the roller 32 is pressed back until it contacts a friction wheel 38 on shaft 39 which is thus rotated and through a reduction gearing in gear-box 40 moves a rack 56 outwards in the direction of arrow B and so forces the spindle housing 11 and thereby the package 16 outwards for a predetermined distance. This action breaks the drive to the wheel 38 until such time as the package size again causes contact between the roller 32 and the wheel 38. During the gradual outward movement of the rack 56 the lever 57 is rocked about pivot 58 and causes the boss 22 and driving disc 21 to be slid along the shaft 23 thereby reducing the rotational speed of the disc 20 and consequently the spindle and traverse speeds. When the package 16 reaches its predetermined diameter or on breakage of the yarn a stop motion operates to disengage the disc 20 from disc 21.

Title: Improvements in fluid pressure control systems for the injection nozzles of compression ignition engines
IPC: F02M47/02
Filed: 1939-07-12
Abstract: 531,133. Valve gear; oil engines. KAMMER, G. S. July 12, 1939, No. 20352. [Classes 7 (iii) and 7 (vi)] A fluid-pressure control system for the rapid release and restoration of pressure in a pipe line for actuating fuel-injection valves comprises a valve with two opposite seatings, one controlling a connection to the fluid supply and the other to an exhaust, while the line to be controlled is in communication with the space in which the valve works, the valve being normally held on to the low-pressure seating by the high pressure, and moved on to the high-pressure seating by elastic means under the control of a timing- arrangement. Fig. 1 shows a valve 7 adapted to close a seating 11 to a fluid-pressure supply 10, or another seating 9 leading to an exhaust 13, while the body of the valve is connected at 12 to the fuel-injection valve, which opens when the fluid pressure in the line 12 is released. In the position shown, the fluid-pressure supply 10 opens the valve and flows into the line 12. The valve is moved down to cut off the supply and open the line 12 to the exhaust 13 by means of a cam 2, which acts on an arm 5 of an elastic torsion bar 3 having a second arm 6 engaging the valve. The cam 2 is tapered so, that the timing may be varied by axial adjustment. In multicylinder engines, the torsion bars 3 are arranged around the same cam 2. A spring may be used in place of the torsion bar, especially with pneumatic systems. The invention may be used with the fuel-injection systems described in Specifications 524,709, [Group XXVIII], 526,723 and 528,042.

Abstract: 1,047,038. Making bearings; bending. GLACIER METAL CO. Ltd. Aug. 13, 1965 [May 15, 1964], No. 20426/64. Headings B3A, B3E and B3Q. A method of making a formed article of laminated construction includes subjecting one face of a laminated blank from which the article is to be formed to a local treating step where a bend is to appear. A bearing blank may be formed by bonding a lining of high tin-aluminium alloy to a steel backing by passing the two component strips together through rollers at a temperature below the melting point of tin. The steel backing is then locally annealed at a temperature below 200‹ C. The heating may be effected by a D.C. or A.C. arc in a protective argon or other atmosphere. The annealing may be effected in two regions parallel to the edges of the strip. Tungsten electrodes may be positioned downstream of a roller which takes out bends across the width of the strip. The strip may be annealed at one arc, cooled, then treated again by a similarly positioned arc. Cooling may be effected by carbon dioxide or jets of water. The electrodes may be transversely vibrated to anneal over a zig-zag path. A plastic, e.g. PTFE, covered steel may be treated. The strip is cut into blanks after treatment.
