Title: Method of and means for winding thread-like material and the product resulting therefrom
IPC: B65H57/28
Filed: 1929-12-17
Abstract: 350,917. Winding thread and like packages. BRENZINGER, J., Fairfield, Connecticut, U.S.A. Dec. 17, 1929, No. 38637. Convention date, July 13. [Classes 120 (ii) and 120 (iii).] Thread &c. is wound in superposed layers, each of which comprises undulating helices of a plurality of complete turns, adjacent layers being wound in opposite directions by a reciprocation and vibration of the thread-guide relative to the rotating bobbin, the vibrations may be of different periodicity in the two directions of the reciprocation of the traverse to form a winding such as that shown in Fig. 7, thus allowing liquids readily to penetrate during dyeing or other liquid treatment. The bobbin 1, Fig. 1, is continuously rotated by gears 4, 5, and the thread-guide bar 7 sliding in guides 8 is traversed by a cam 9 having cam rollers 13 and a guide 11 for reciprocating a rack member 12 engaging a pinion 15 on the same shaft as a pinion 16 which engages a rack 17 on the bar 7, which also carries a bracket 24 with bearings for a sprocket 25 meshing with a chain 26, driven as shown from the cam wheel. The sprocket 25 has a crank pin 22 which vibrates the thread-guide 3 by the link 20 and lever 19, the periodicity of the vibration being shorter as the sprocket 25 advances to the right in Fig. 1, against the movement of the chain. In a modification the traverse is moved as above described and the bobbin shaft also reciprocated by a gear section &c. driven from the pinion 16, the gear 4 rotating the bobbin shaft through a gear splined thereon. Further modifications are described wherein the vibrations are of constant periodicity and are effected by a constantly rotated crank having link connections &c., the traverse being effected by a cam driven lever &c.

Title: Process for the removal of sulphur dioxide from gas mixtures and redox catalysts for use in this process
IPC: C01B17/60
Filed: 1965-09-13
Abstract: SO2 is removed from an oxygen-containing gas mixture by contact above 300 DEG  C. with a redox catalyst consisting of copper oxide on a carrier.  In examples flue gas containing CO2, O2, N2, H2O and SO2 is passed through a tubular reactor at 410 DEG  C.  SO2 is removed and the spent catalyst containing Cu2S and CuSO4 is regenerated at 430 DEG  C. in a methane atmosphere. The copper catalysts may be promoted with Pd and/or Cr and/or Ag, and stabilized with BaO. The redox reactions may be summarized by the equations: CuO + SO2 + 1/2 O2--> CuSO4 reduction CuSO4 --> CuO + Cu2O + Cu + Cu2S Cu2O + 1/2 O2 --> 2CuO Cu + 1/2 O2 --> CuO Cu2S + 2 1/2 O2 --> CuO + CuSo4.ALSO:Redox catalysts for removing SO2 from gaseous mixtures containing O2 comprise copper oxide on a carrier.  Preferred carriers are Al2O3, SiO2, Al2O3, -SiO2, SiO2, -MgO on mixtures.  Specified promoters are Cr2O3 and/or Pd and/or Ag.  The catalyst may be stabilised with BaO. The catalyst carrier may have a surface area of at least 100m2/gm. An example describes CuO, Cr2O3, Ag and Pd or Al2O3.  Pore volume data for carriers is also disclosed.

Title: Coal drying
IPC: F26B11/02
Filed: 1961-11-07
Abstract: 932,099. Rotary drying drums; drying coal. W. L. PRITTS. Nov. 7, 1961 [May 5, 1961], No. 39760/61. Class 34 (2). In a process of drying combustible material, e.g. batches of coal, the material is dried in a rotary drying drum by the passage of hot gas therethrough, the dried coal and gas discharging from an outlet portion of the drum, and at least a portion of dried, pulverulent material being utilized as a main fuel to a combustion chamber to which it is fed together with at least a stoichiometric quantity of oxygen to provide the hot gas for the drying process. Batches of combustible material, e.g. coal, are dried in a rotary drying drum 40, which is rotated by an external ring gear 45 and which has rows of lifting vanes (not shown), by the passage therethrough of heated air produced in a stationary combustion chamber 24 by burning dried coal dust with a pilot flame which dust has been separated from the dried product. The dust is burned in a sufficient, but preferably excess, quantity of air to assure full combustion of the coal dust and the resultant hot gas is tempered in a non-rotatable chamber 35 through which the batch is introduced by a shoot 37 for entry into the rotary drum 40, the chamber 35 being intermediate the chamber 24 and drum 40 and the tempering, atmospheric air entering through ports 35c in the chamber 35. The dried coal passes from the drum to a discharge chamber 55, the larger particles being discharged on an endless belt conveyer 60 and the fires being carried upwardly by the hot gas through a duct 70 to a cyclone separator 75, the dust passing through a downwardlyconverging portion 75a and duct 78 to the conveyer 60 and the hot gas being exhausted to atmosphere through a discharge duct 80 by a suction blower 81. The portion of dried dust to be used as fuel is withdrawn from the duct 78 by suction applied to a branch duct 79, into a secondary separator 85, the suction being applied to the top of the separator by a suction duct 73 connected to the duct 70 and through which the separated gas is exhausted while the dust is discharged into a horizontal delivery duct 92 connected to a main supply duct 31. The duct 92 has a screw conveyer driven by a motor 95 which is variably driven via a potentiometer unit 110 in proportion to the temperature indication given by a thermocouple 71 in the duct 70 so that the rate of feed of the dust is controlled in accordance with the temperature of the gases leaving the drum. The dust is conveyed into the combustion chamber 24 by air from a blower 100. The pilot flame is supplied by an auxiliary fuel e.g. oil vapour, and air through pipes 13, 12 respectively to a chamber 10 mounted centrally of the inlet end of the combustion chamber 20 to provide a flame at all times during the drying operation, which flame may be turned off by a valve 14 in the supply line controlled from a main control electrical unit B and relit by a spark plug igniter 20.
