Title: Variable speed transmissions for automotive vehicles
IPC: F16H47/08
Filed: 1957-05-07
Abstract: 836,569. Variable-speed gears. BORGWARNER CORPORATION. May 7, 1957 [May 8, 1956], No. 14516/57. Class 80 (2). A variable-speed gear for a vehicle, providing a low speed forward and reverse, a split-torque direct drive, and hydrodynamic braking by simultaneous use of direct drive and reverse, comprises planets carried by a final output shaft 11 and directly meshing a ring gear 29 fast with a torque converter turbine 21, and a sun 34 on an intermediate shaft 12, which also carries the driven disc of a clutch 15 which, together with the converter impeller 19 is fast on an input shaft 10, whereby with the clutch 15 engaged, the ring gear 29 and sun 34 are both driven at substantially equal speeds the former through the converter the latter through the mechanical clutch for split torque direct drive. For low speed forward drive, a brake 17 is applied to an equal sun 35 which thus also holds the sun 34 so that the train, in reduction, is driven wholly in series through the converter. Reaction of the converter reactor 24 passes through a oneway device 27 to the now-stationary intermediate shaft 12. For reverse, a brake 16 holds the connected ring gear 36 and turbine 21, and the reactor 24, rotating reversely, drives the sun 34 through the one-way device 27, the train still reducing and still in series with the converter. Input and output driven pumps 47, 48 supply pressure for operating the brakes and clutch.

Patent GB-128206-A (GB)
Title: Improvements in and relating to Reversing Gearing.
IPC: F16H59/00
Filed: 1919-06-10
Abstract: 128,206. Aktiebolaget Ljungstr÷ms Angturbin. June 12, 1918, [Convention date]. Connecting and disconnecting arrangements.- Gearing of the kind in which toothed wheels are moved in their own planes into mesh is operated hydraulically so that the change of mesh can be effected only when the toothed wheels are at rest and the teeth to be intermeshed are in proper relative positions. A driving pinion 1 is secured to a fixed shaft 4. The wheel 2 to be driven is supported in a pivoted frame 16 so that it can be intermeshed with the pinion 1 for forward driving. An idler 3 supported eccentrically in a revoluble disk 18 is adapted to be intermeshed with the pinion 1 and with the wheel 2 for reversed driv ing. The disk 18 is connected by a link 19 and a crank to a shaft 13, which carries a cam 14 working in jaws in the frame 16. Turning the shaft 13 by a hydraulic cylinder 7 effects the change of mesh. The toothed wheels are brought to rest prior to changing mesh by friction segments 37, 38 thrust hydraulically against friction rims upon them. The gears 1, 3 are turned to bring teeth everywhere opposite spaces prior to meshing by pawls 26. An operating-lever 30 pivoted to a valve 32 is interlocked by spring detents 57 with the throttle or like controlling-lever 56 of the source of power, so that the lever 30 can be moved only when the motor is stopped. The toothed gearing is locked during power transmission by a detent 47a on a shaft 46 engaging a recess in a disk 48<a> secured to a shaft 50, which is connected by gearing 49, 51 to the shaft 13. Gearing 48, 52 connects the shaft 50 to the shaft 46, which can move up and down, and at its upper end may or may not engage the pivot 76 of'the lever 30, so preventing the lever 30 being improperly moved The valve 32 is turned about its axis by the lever 30 to change mesh by way of a cylinder 7. The first possible movement is a downward one of the lever 30 depressing the valve 32 and operating the disks 37, 38. If the wheels are in motion, a rod 43 rises and locks the lever 30, so that the valve 32 cannot be turned. This operation is repeated till the rod 43 does not rise. Further downward movement admits fluid under the .end of the shaft 46 raising it and unlocking the shafts 50, 13. This movement also operates the pawls 26. The valve 32 can then be turned to effect the change. Compressed air may be used instead of water or oil under pressure, and helical toothed gearing may be employed.

Title: Improvements in the manufacture of cellulose
IPC: D21C9/08
Filed: 1934-05-16
Abstract: A cellulose of a high degree of purity, suitable for the preparation of cellulose derivatives or for the manufacture of paper, is prepared from chemical wood pulps by extraction with an alkaline solution, for example, a solution of caustic soda or sodium sulphide, which already contains a substance extracted from wood by treatment with alkali. Thus, to the alkali solution used for the extraction there may be added a solution prepared by extracting wood chips with caustic soda; or, alternatively, with the sulphite pulp to be treated there may be mixed sawdust or wood powder, and the whole extracted with caustic soda solution.  For the alkali extraction there may be used cold concentrated caustic soda solution, or preferably alkali of lower concentration, but at raised temperatures up to the boiling point or even at higher temperatures as permitted by the application of pressure; or alternatively, the pulp may first be treated with hot dilute alkali, and then with cold stronger alkali.  After the alkali treatment, the cellulose may be subjected to a chlorine &c. bleach. Specifications 263,938 and 312,098, [both in Class 2 (ii)], are referred to.
