Title: Gas-liquid contact reaction
IPC: B01J19/18
Filed: 1971-06-15
Abstract: 1343447 Treating liquids with gases BRIDGESTONE TIRE - KK and MITSUBISHI JUKOGYO KK 15 June 1971 [15 June 1970] 27935/71 Heading B1R [Also in Division C3] Apparatus for carrying out a gas-liquid contact reaction comprises a horizontal cylindrical reactor 3 surrounded by a cooling jacket 5, two driving shafts 1 in the reactor rotatable in opposite directions and each being provided with members 2 projecting therefrom, the members on the respective shafts being staggered and arranged to overlap. In use a solution of a high molecular weight polymer of high viscosity dissolved in a solvent of high volatility may be charged into the reactor through an inlet 6, and a reactive gas charged through an inlet 8 so that when the drive shaft 1 and members 2 are rotated shear mixing takes place to constantly renew the gas-liquid surface and allow a steady gas-liquid reaction to take place. Solvent evaporated by the heat of reaction is condensed and runs down the cooled side walls of the reactor to be drawn back into solution and a raised base 17 may be provided to aid this process whereby condensed solvent is gathered into the solution by the rotating members 2. The driving shafts are inclined towards an outlet 7 to move the solution towards the outlet, and a scraper 18 is provided adjacent the outlet to remove solution from the projections 2. Alternatively the projections 2 are inclined towards the shaft, or feeding grooves provided on the base of the reactor to move the polymer solution.

Filed: 1926-11-08
Abstract: 261,038. British Thomson-Houston Co., Ltd., (Assignees of Buckland, B. 0., and Warren, G. B.). Nov. 6, 1925, [Convention date]. Variable-speed gearing. - A turbine drives a gear 28 through a pinion 34 for high speed and through reproducing-gear formed by a pinion 36, gear-wheel 40, and pinions 43, 34 for cruising speed. Clutches 49, 61 are provided for coupling the pinion 43 to the shaft of the gear-wheel 40, and the pinion 34 to the turbine shaft, an extension of which carries the pinion 36. A hand. lever 73 controls the clutches 49, 61 through a rod 72, pivoted cams 57, 68, rods 54, 66 and toggle devices 52, 64, so that one clutch is disengaged before the other is engaged. An interlocking device is provided between the rod 72 and the shaft 6 operating the inlet valves 2 so as to prevent the clutches from being thrown when the valves are open. It comprises a cam 75 on the shaft 6, Fig. 5, which actuates a bar 77 sliding in a groove 80, 81 in a sleeve 79 on the rod 72, which is thus held against movement until a slot 78 in the bar 77 registers with the sleeve 79, this corresponding to the closed position of the valves 2. For increasing or retarding the speed of the turbine rotor in order to synchronize the clutch members before engaging them, a lever 96, Fig. 2, is provided having an arm 95. When moved in one direction, this arm opens a valve 93 and admits additional working-fluid to the highpressure nozzles by way of a pipe 92. When moved in the other direction, the arm 95 opens a valve 101 and discharges fluid through a pipe 100 so as to retard the turbine speed. Clutches.-Fig. 7 shows a device for indicating the relative speeds of the clutch members. The speed of the gear 28 and hence the speeds of clutch members 48, 60 are indicated by a small synchronizing generator 82 having its shaft 82<a> connected to shaft 82. For indicating the speed of clutch members 49, 61, there are provided two small synchronizing generators 83, 84 geared to a shaft 85 forming an extenison of the shaft 46 carrying the gear 40, the rear ratios being such that one generator indicates the speed of shaft 46 and the other the speed of shaft 39. Two synchronous motors 86, 86<a> have their shafts connected to bevel gears 87, 88 of a differential gearing. A pointer 90, carried by the gears 89, remains stationary when the wheels 87, 88 run at the same speed. Motor 86 is electrically connected to generator 82, and indicates the speed of clutch members 48, 60, whilst motor 86<a> is connected by a switch 91 either to generator 83 or to generator 84 so as to indicate the speed of either clutch member 49, 61.

Abstract: 720,358. Bearings. GENERAL ELECTRIC CO. Nov. 14, 1952 [Nov. 20, 1951], No. 28802/52. Class 12 (1) A thrust bearing for a shaft 1 comprises thrust plates 5, 7, Fig. 1, provided with axial holes 5a, 7a, each hole communicating with a diametral groove in its plate, such as 7b in plate 7. The function of these grooves is to cyclically reform the lubricant film on the thrust bearing surfaces 6b of a disc 6, the disc being provided with an axial hole 6c and radially extending grooves 6a, Fig. 2, of cross section as shown in Fig. 4. Radial passages 6d are also provided for the circulation of cooling oil. The plates 5, 7 are frictionally or otherwise prevented from rotation relative to their seats in the support member 4 and the shaft respectively. Oil at 30 lbs. p.s.i. is admitted through an inlet port 9 whence it flows through the axial holes to the grooves 6a, 7b and the passages 6d. Used oil is collected in an annular chamber 9a and is discharged via drain ports 10 and 10a. In operation, rotation of shaft 1 to whicH plate 7 is secured will induce rotation of the disc 6 at a speed intermediate that of the plate 7 and the stationary plate 5, thus causing oil to flow from the grooves 6a up the incline 6h, Fig. 4, and be distributed in a film over the thrust surfaces 6b. The members 5 and 7 are preferably of sintered tungsten carbide and may operate with thrust loads of 10,000 lbs. p.s.i. at 10,000 r.p.m. In a modification, a thrust-bearing member is seated in the shaft and co-operates directly with a thrust plate 5.
