Title: Improvements in or relating to speed governors for compression ignition engines
IPC: F02D1/00
Filed: 1953-06-01
Abstract: 722,725. Fluid-pressure servomotor-control systems. PERKINS, Ltd., F., and CONDIE, J. R. June 1, 1953 [March 3, 1952], No. 5518/52. Class 135. Means for regulating the speed of fuel-injection compression-ignition engines of the kind in which the fuel pump rack 6 is actuated by a spring-loaded diaphragm 5 subject to pressure in the induction manifold 1 communicated through a pipe 4, comprises means responsive to engine speed for varying the pressure in the induction manifold. As shown, a diaphragm 9 connected by an adjustable link 12 to the engine butterfly valve 2 and biased by a spring 14 is connected by a pipe 11 to the pipe 4 so that a variation of engine speed, giving rise to a change of pressure in the induction manifold, causes the butterfly valve to be adjusted so as to cause the diaphragm 5 to vary the fuel delivery. In a modification, the butterfly valve is adjusted by a centrifugal governor instead of by the diaphragm 9. The relative positions of the butterfly valve and the diaphragm 9 or the output member of the centrifugal governor may be varied by a hand control operating either on the linkage between those parts or on an eccentric associated with the butterfly spindle. It is stated that electric or hydraulic transmission may be provided between the butterfly valve and the speed responsive means and that the latter may, alternatively, be electric or hydraulic.

Filed: 1948-02-25
Abstract: 654,272. Making pellets from finely-divided solids. MONSANTO CHEMICAL CO. Feb. 25, 1948, No. 5595. Convention date, July 19, 1943. [Class 87 (ii)] Pellets of phthalic anhydride, ferric sulphate, aluminium sulphate or sodium sulphate are formed by placing a mass of the substance, in a finely-divided state, in a drum 10, rotating the drum, and continuously supplying, through a pipe 18, additional finely-divided solids and either a substance which is a liquid, e.g. water, an aqueous solution of the substance or the substance in a molten state, or a substance which is solid but which melts on heating to react with the finely-divided solids into the mass of the substance below the surface of the mass. The liquid is preferably fed into a sparsely-filled region A, Fig. 2, caused by the rotation of the drum. By adjusting the amount of liquid and additional finely-divided material added to the drum, the material in the region A is kept relatively plastic. The temperature of the material may also be controlled by cooling or heating the drum, and cooling or heating the additional finely-divided solid material. The additional material is supplied by transferring pellets from the drum 10 to screens 25, 26 by screw conveyers 20, 21 and then feeding the fines through a pipe 30, and some of the pellets, after being ground in a grinder 28, through pipe 29, back to the drum by a conveyer 17. The drum may be inclined to increase the capacity of the drum and to remove selectively from the drum, the larger pellets. The pellets may be cooled, heated or dried after formation. Specification 654,246 is referred to. The Specification as open to inspection under Sect. 91 comprises also carrying out the process without the addition of finely-divided solids, by continuously supplying only hot molten liquid. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the treatment of natural rubber latex
IPC: C08C1/08
Filed: 1947-03-03
Abstract: Natural rubber latex is separated into yellow and white liquid fractions by adding an alkaline substance such as ammonia to bring the pH from 6.8 to 8.8 and then adding an aqueous solution of a magnesium salt such as magnesium sulphate to provide a final concentration of 0.015 to 0.100 grammol of magnesium ion equivalents per litre, and allowing to stand till separation into two layers is effected.  The latex is preferably diluted before treatment.  The two layers may be separated and then either retained as latex in which case the pH should be raised, or else coagulated Alternately, the layers may be allowed to stand until the yellow layer coagulates, the coagulum then being removed to leave a white low-nitrogen content latex.
