Abstract: 638,325. Fluid-pressure servomotor-control systems. BRYCE FUEL INJECTION, Ltd. Nov. 18, 1947, No. 30576. [Class 135] A hydraulic governor, e.g. for variable-speed fuel injection engines comprises an enginedriven pump in a liquid circulating system, a manually-variable leak-off orifice, and a spring- loaded control plunger subject to the pressure downstream of the orifice while a constant pressure is maintained upstream of the orifice. A three-gear pump 7, 8, 9 delivers liquid from the chamber 2 to the passage 12 leading to one or more orifices 18 in the cylinder 19 in which slides a plunger 20 connected to the engine fuel control member and loaded by the spring 21 to move the control member to the minimum fuel position. The plunger has one or more grooves 23, the edges of which control the orifices according to the angular position of the plunger when rotated by a speed control lever. The pump draws liquid from the cylinder through the passage 11 while a constant pressure is maintained in the passage 12 by a spring-loaded release valve 15 controlling the return passage 17 to the chamber 2. In a modification, the gear pump is replaced by two pumps in a chamber connected to the orifice and the release valve. One pump maintains a constant pressure in the chamber while the other draws liquid from the control cylinder and delivers it to the chamber.

Abstract: 533,831. Sugar-cane mills. COLONIAL SUGAR REFINING CO., Ltd. Dec. 1, 1939, No. 31272. Convention date, Dec. 30, 1938. [Class 59] A sugar-cane mill is provided with means for enforcing entry of the cane between the rollers of the mill train, and with means for indicating a deficiency in the feed to the rollers. The mill comprises a conveyer 1 for delivering cut cane or megass to feed rollers 5, 6 from which the compacted cane passes to a train of crushing rollers 30, 31, 35. The cane falls from the conveyer into a hopper head 2 which is extended forwardly to provide space for excess feed. The hopper walls 7, 10 diverge slightly towards the rollers 5, 6, are inclined to the vertical, and terminate close to the surfaces of the rollers. A septum 9, arranged in the hopper neck, has its lower end at a distance from the roller 6 and provides a passage 11 for any cane which may pass between it and the wall 10. A tappet 12, pivoted at the foot of the septum, is connected to a self-opening switch 15 in the circuit of an alarm lamp 16 which is lighted when any material passes through the passage 11. Three tappets 17, 18, 19 project through the wall 7 into the space 24 through which the whole of the feed normally passes, and they are rocked by the pressure of the mass of descending cane. The uppermost tappet, 17, is connected by a link 20 to a device controlling the supply of steam or electricity which drives the mill. When the feed from the conveyer is below normal, the tappet 17 is not rocked and the drive of the mill is retarded. If the supply of cane continues to fall below normal, the tappets 18 and 19 are successively released and switch on signal lamps 21, 22, respectively. The compacted cane from the rollers 5, 6 is forced downwards through a tubular shoot 23 of rectangular section. The top and bottom of the shoot diverge slightly in a downward direction, and the upper and lower ends are arranged close to the rollers. Any juice extracted by the rollers 5. 6 is caught by a pan 31x and flows thence through a pipe 34. The cane is forced by the rollers 5, 6 positively into the shoot 23 and reaches the rollers 30, 31 in a compacted condition.
