    Abstract: 382,890. Rotary drying drums. DUNCAN STEW ART & CO., Ltd., London Road Iron Works, Glasgow, ANIMAL FOOD PRODUCTS, Ltd., Felstead, Essex, and CROSBIE, J. B. TALBOT-, Raheen, Chesters Road, Bearsden, Dumbartonshire. May 6, 1932, No. 13086. [Class 34 (ii).] A revolving drum through which passes material subjected to the drying action of hot air or gas introduced through the circumferential wall of the drum is constituted as a perorated shell which is machined externally so as to be truly cylindrical and smooth. The drum may be formed in sections aligned and interconnected by flanged rings. The hot gas is introduced into the drum through elongated supply ports each of which is narrow circumferentially of the drum but may extend nearly the whole axial length of one division of the drum. The ports are framed with wide sealing flanges conforming closely to the curvature of the drum and approximated closely to the drum to minimize gas leakage. These flanges are constructed as or backed by ducts for cooling water, and may be faced with wired asbestos composition or like fibrous material. As shown in the drawings, the perforations in the drum 1 are countersunk on the inner surface, and the flanges 4 of the gas supply ports 3 are faced with fibrous material 5 and cooled by water entering by the port 6 and leaving by the port 7.

    Abstract: 368,088. Liquid pressure engines. DUNCAN STEW ART & CO., Ltd., HOLMES, E. P., London Road Iron Works, Glasgow, IMPERIAL CHEMICAL INDUSTRIES, Ltd., and GOODFELLOW, B. R., Millbank, London. March 23, 1931, No. 8810. [Class 69 (ii).] In an installation in which liquid is supplied by a pump to apparatus from which it is discharged at a pressure above atmospheric, the discharge liquid is utilized for assisting the pump drive. The discharge liquid is led by a pipe 8 to a drive cylinder 1 coaxial with the pump 2, the cylinders having aligned rams 3, which may be of the same or different diameters. The valve box 4 of the cylinder 1 is controlled by timing-gear 5. The drive ram 3 is assisted by an auxiliary ram 14, the cylinder of which is supplied by an auxiliary pump 9 through pipes 11, 12. The return movement of the rams 3, 14 is effected by a ram 15 subjected to constant pressure. The Provisional Specification states also that the auxiliary pump may supply liquid also to the main drive ram, or the auxiliary drive ram may be dispensed with.

    Abstract: 327,531. Stewart & Co., Ltd., D., and Holmes, T. E. March 1, 1929. Actuating by liquid pressure; valve gear.- Apparatus for forcing viscous liquids comprises one or more rams 1, Fig. 1, each working in a hydraulic cylinder 4 and a cylinder 2 for the viscous liquid, the latter cylinder being provided with inlet and delivery valves 10, 11, the operation of which is controlled by the pressure valve of the hydraulic cylinder. The valves 10, 11 are connected to pistons 13', 18 in cylinders 14, 19, one side of the pistons being always under pressure admitted through pipes 16, 20 supplied from a pipe 25, which also supplies the cylinders 6 of rams 5 for effecting the return stroke of the ram 1. Hydraulic pumps are connected by pressure and return pipes 35, 41 to a valve block 29 fitted with a pressure valve 30, Fig. 3, exhaust valve 31, non-return valve 32, and a valve 33, and the pipe 41 is also connected to a storage tank. During the return stroke of the ram 1, the valve 10 is open so that viscous liquid may enter the cylinder 2, and a lever 74 is in the position shown, so that the exhaust valve 31 is open and the valve 30 closed to allow liquid from the cylinder 4 to pass through the pipe 38, non- return valve 32, and valve 31 to the pipe 41 . At the end of the return stroke, a tappet 105 acts through members 102 to remove a detent 97 from engagement with a member 92; a weight 89 then actuates the lever 74 to open the valve 30 and allow the exhaust valve 31 to close. Pressure liquid then passes from the pipe 35 through the valve 30 into a chamber 40, whence it passes through the pipe 23 to close the valve 10, and through a pipe 55 to close a valve 51 to prevent passage of liquid through a pipe 52 to the storage tank. When the pressure in the chamber 40 reaches a predetermined valve, it acts on a shoulder 106 to open the valve 33 and obtain access to the pipe 38 leading to the cylinder 4; finally the pressure acts through the pipe 23 to open the valve 11, and the forward stroke of the ram 1 is commenced, continuing until a cam 81 returns the lever 74 into position to allow the valve 30 to close to open the exhaust valve 31, and to move the member 92 into engaging position with the detent 97.

    Abstract: 320,826. Stewart & Co., Ltd., D., and Crosbie, J. B. Talbot-. Jan. 14, 1929. Extracing sugar; purifying saccharine liquids. -In the manufacture of sugar where the sugar is extracted by diffusion and the juice is purified bv treatment with lime and carbon dioxide and filtered, the sweet water separated from the pulp and the water pressed from the pulp in pulp presses is neutralized by means of the filter press cake from which it removes residues of sugar. The neutralized water is refiltered and returned as diffusion water to the diffusion process.
