Title: Hydromechanical change-speed gear
IPC: F16H47/08
Filed: 1963-07-15
Abstract: 1,045,834. Change-speed gear; hydromechanical change-speed gear; hydraulic clutches. C. SOHULEB-VOITH, M. VOITH, H. W. SCHWEPPENHAUSER, and C. KNAPP, [trading as VOITH-GETRIEBE KOMM. GES.]. July 15, 1963 [July 21, 1962], No. 27999/63. Headings F2C and F2D. A countershaft change-speed gear comprises an input shaft 14 carrying a gear 18 meshed by three gears 19, 20, 21, Fig.. 2 (not shown), selectively coupled to countershafts 22, 23, 24, disposed equiangularly about the axis of the input shaft, by engagement of hydraulically or pneumatically controlled multi-disc clutches 25, 26, 27, gears 28, 29 on the countershafts 22, 23 meshing directly with gears 33, 34 on an output shaft 32 for two forward speeds while a gear 30 on the countershaft 24 meshes through an idler 31 with the gear 33 for reverse. The input shaft 14 is itself the output shaft of an hydromechanical change-speed gear consisting of an hydrodynamic torque converter 8 preceded by a torque-splitting planet gear 3. An engine-powered shaft 1 drives a ring gear 2 meshing the planet pinions of the torquesplitting gear 3 in turn meshing a sunwheel 5 connected through a ratchet clutch 6 with the pump 7 of the torque converter 8. A lock-up clutch 17 is engaged for a direct drive through the torque-splitting planet gear 3 to a shaft 4. integral with the shaft 14. The torque converter turbine 9 drives a sunwheel 10 meshing planets 11 carried on the shaft 4 and meshing a ring gear 12 stationed by engagement of a disc brake 15. To establish a low ratio drive through the hydromechanical gear with torque splitting, the disc brake 15 alone is engaged, to station the ring gear 12. An all-mechanical ratio is established by releasing the brake 15, and instead engaging an hydraulically operated brake 16 within the torque converter 8 to station the turbine 7 and sunwheel 5. A further allmechanical ratio (direct drive) is now established by also engaging the lock-up clutch 17. Over-run braking can be obtained by engaging the lock-up clutch 17 simultaneously with the ring gear brake 15, thus driving the turbine 7. Alternatively, the torque converter may drive to the change-speed gear through an additional countershaft and pair of gears.

Title: An improved process for the separation of finely divided solids from mixtures thereof
IPC: B01J8/34
Filed: 1947-10-20
Abstract: 647,914. Drying apparatus. STANDARD OIL DEVELOPMENT CO. Oct. 20, 1947, No. 28056. Convention date, Feb. 5. [Class 34(ii)] [Also in Groups II and XII] During the process of separating a mixture of finely divided solids such as raw coal, chalcocite copper ore or grain seeds, into its components by passing a gaseous stream upwardly through a deep bed of the mixture confined in a separator (see Group II) the gaseous stream may be heated to an elevated temperature such that moisture is expelled from the mixture that moisture is expelled from the mixture of solids, or such that the coal is preheated for use in carbonization or partially devolatilized (see Group XII). As shown gas or air supplied from valve 8 and conduit 5 passes up through the bed contained in the separator 1 and is discharged from the top through conduit 10. A combustion reaction may be promoted in the bottom zone E of the bed, by introducing gas or other fuel supplied through valve 7 and conduit 6 and burning it in the gas stream supplied through valve 8 and/or 9 to fluidize the solids in the separator. In the separation of finely divided raw coal when small amounts of combustible matter pass out of the bed with the heavier ash, this combustible matter may be burned to supply the heat for the fluidizing gas. Specification 600,326, [Group II], is referred to.
