IPC: C04B11/02
Filed: 1958-08-05
Abstract: <PICT:0897925/III/1> <PICT:0897925/III/2> In the dehydration of gypsum to the hemihydrate in a sealable indirectly heated vessel which is alternately sealed for at least 3 minutes and then vented until the desired dehydration has occured, a minimum positive gauge pressure is maintained in the vessel until the dehydration is completed.  The temperature is maintained below 330 DEG F. during the alternate venting and sealing but finally when the dehydrating chamber is sealed the temperature rises to 330 DEG F. whilst the pressure remains below that previously attained.  Venting is generally effected at 30 to 40 p.s.i.g.  The minimum gauge pressure is generally from 4 to 6 p.s.i.g. and the temperature on venting should not drop below 212 DEG F.  The apparatus employed is the same as that disclosed in Specifications 866,126, 897,923 and 897,924.  As shown in Figs. 1 and 2, a drum 7 is supported by and rotated with an axial pipe 21 which rests on rollers 5 carried by support 2.  Inside the drum the tube 21 carries a concertina-like arrangement of annular dished members 26 peripherally joined to form a series of chambers communicating with the interior of pipe 21 through perforations 25. A gas burner 22 delivers a blast of hot combustion products into pipe 21 from the left-hand side and these gases pass through perforations 25 into the chambers 33 formed by the annular dished members 26. The chambers 33 communicate with tubes 8 (Fig. 2) formed in the walls 7 of the container, by means of pipes 30.  Tubes 8 are provided with exhaust passages 31 having a terminal elbow whereby the hot combustion gases from chamber 33 pass through connections 30 into tube 8 and out through exhaust 31 in contact with the exterior of the drum 6.

Patent GB-256472-A (GB)
Abstract: 256,472. Jackson, W. J. Mellersh-, (Perfecto Gear Differential Co.). Jan. 15, 1926. Variable-speed and reversing epicyclic gearing comprises a plurality of planet gears 26, 27, 31, 32, 33 on a jack shaft 23 which is geared both to a housing 6 secured to a driving-shaft 9 and to the driven shaft 16, and a plurality of centre gears 49, 41, 42 adapted to be meshed with planet gears alternatively. One planet gear 27 meshes with an internally-toothed ring 7 secured to the housing 6. The inner end of the driven shaft 16 is splined into a driven sun gear 17 which constantly meshes with planet gear 26. The jack shaft or shafts are carried in a loosely revoluable cage 22. The centre gear 49 is fast on a revoluble sleeve 51, which carries also a gear 52. When the sleeve 51 is slid to the left, the gear 49 enters into clutch engagement with internal teeth 53 upon the sun gear 17, and the gear 49 meshes with the planet 27. The result is a solid or first high-speed drive. When the sleeve 51 is moved to the right, the gear 49 meshes with the planet 27 and is held against rotation by clutch dogs 54 engaging filed dogs 56. This cause the sun 17 to be driven at lower high speed. Upper and lower low speeds are effected by sliding to left end right a non-revoluble sleeve 37 carrying centre gears 41, 42. Reversed driving is effected when the sleeve 37 is slid farther to the right until the gear 42 enters into clutch engagement with teeth 36 inside a sun gear 34, which is larger than the driven sun gear. The sleeves 51, 37 are operated by bars 63, 67 which slide in guides in a fixed frame 64. A doubly pivoted control lever 71 is moved transversely of the gear into notches 72, 73 in the bars respectively to select, and longitudinally to operate. The edges of the notches are bevelled at 74 to allow of the angular motion. In Fig. 5 are shown the positions of the control lever, two high speeds, two low speeds, two neutrals, and reverse. The bars are interlocked by a ball 75 and are locked in gear positions by a bent spring 76 supported on a stud 77.
