Title: Sugar refining process
IPC: C13B20/18
Filed: 1971-04-19
Abstract: 1350261 Purifying sugar juices HITACHI SHIPBUILDING & ENG CO Ltd 19 April 1971 [16 Oct 1970] 25254/71 Heading C6B In a process for the production of plantationrefined sugar the juice extracted from the cane or other sugar-bearing raw material and heated to about 55C is subjected to a continuous carbonation process by being passed through a first carbonator in which milk of lime and CO 2  gas are added and then, after separation of calcium carbonate precipitate, through a second carbonator, followed by a heater which facilitates subsequent filtration to remove calcium carbonate. The juice is then decolorized by means of granular active carbon and subjected to further purification, i.e. decoloration, dechlorination and removal of salts and organic non-sugar material, by passage through a combination of ion-exchange apparatus comprising an electrodialysis membrane and cation and anion resin towers, and a succession of evaporators. In one embodiment, the juice leaving the ion exchange apparatus is passed through a monobed tower to complete the dechlorination and adjust the pH value to prevent subsequent inversion, and then through a heater and a succession of four evaporators followed by a vacuum pan and a centrifugal machine in which the molasses is separated. The refined sugar is then crystallized in a cooler and dryer and sieved and bagged. In an alternative arrangement only one evaporator is positioned as indicated above, three others being located immediately upstream of the ion exchange apparatus.

Title: Improvements in and relating to electric motor controllers
IPC: H01H3/40
Filed: 1919-10-15
Abstract: 156,346. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 15, 1919. Gearing, ratchet. - Consists in an arrangement of ratchet and spur gearing connecting an operating handle to a drum controller shaft, which has the following functions:- (1) To-and-fro action of handle produces slow forward movement of controller. (2) After a certain range, or optionally at any time, continuous forward movement of handle produces quick forward movement of controller. (3) Continuous backward movement of handle produces quick backward movement of controller. In the construction shown the first function is performed by a pawl 21 driving a ratchet wheel 12, the pawl being pivoted on a frame 17 which turns with the handle 10 about an axis 10<1>, and the ratchet being in connection through spur wheels 13, 14 with the controller shaft 11. The second function is performed by a stop 24 attached to the frame 17, encountering the edge of a toothed sector 15 in gear with a smaller spur wheel 16 on the controller shaft. In normal starting the movements of the stop are idle until the first part of the forward travel has brought the sector 15 within range, and during the first part of the travel the extent of the handle is limited by a stop pawl 32 which drops into teeth of a stationary ratchet 31. The action of the pawl 32 is superseded, after a definite range, by its arrival on the smooth part of the ratchet 31. If continuous movement is desired at an earlier stage, the operator throws over a releasing handle 36, which lifts the stop-pawl clear of the ratchet. The third function is performed by a lug 25, similar to the lug 24, but adapted to encounter the opposite edge of the sector 15 when the handle is turned back. A pin 26 meets the pawl 21 and lifts it clear of the ratchet 12 in order that these parts may run back freely.
