Abstract: 682,710. Change-speed gearing. HOBBS TRANSMISSION, Ltd. May 9, 1951 [May 16. 1950j, No. 12180/50. Class 80 (ii). Change-speed epicyclic gearing comprises two intermediate shafts 33, 35 adapted to be connected to a driving flywheel 10 by oil-operated plate clutches 31, 30 and having integral sun gears 36, 37 meshing with double planets 40, 41 in a carrier 43 rigid with an output shaft 44, the planets 41 meshing also with a ring gear 45 rigid with the carrier 47 of a secondary train the planets 49 of which mesh with a ring gear 55 secured to carrier 43 and with a sun gear 56, the carrier 47 and sun 56 being adapted to be braked by oil-operated brakes 51 and 58. Four geared speeds are obtained by engaging one or other of the clutches with one or other of the brakes, and direct drive is secured by engaging both clutches. Pressure oil for engaging the clutches and brakes is supplied, under the control of a selector piston valve, from pumps 85, 94 driven from the flywheel 10 and shaft 44. Spring-loaded centrifugally-balanced valves 99 in the flywheel are moved inwards by the oil pressure to open ports 101 leading to the diaphragm spaces 29, and, on relief of the pressure, move outwards to allow the spaces 29 to exhaust through ports 102 into the casing. Other spring-loaded valves 104 operate centrifugally to exhaust the spaces 29 through ports 106 at or below engine idling speed. When the engine is stopped, the valves 104 move to their innermost position in which the ports 106 are closed, so that the engine may be started by towing. In the form shown in Fig. 2, a sixth (overdrive) speed is obtained by engaging the clutch 31 and a brake 108 on the shaft 35. Further, the secondary gearing has double planets 111, 112 meshing with the sun 56, the ring gear 55 and a ring gear 113 carrying a brake 115. By engaging brake 115 and one or other of clutches 30, 31, two reverse speeds are obtained. Specifications 628,499, 628,523, 637,236, 637,251 and 644,173 are referred to.

Washers.-A number of washing-chambers are superposed one upon another or arranged side by side, and the washing water or liquid is continuously circulated through each chamber. In the arrangement shown in Fig. 1, a number of chambers are formed by a tier of trays C, C<1> - - Cx each provided with slotted openings J having lips extending upwards, and with pointed projections extending downwards from the undersides. The slotted openings in alternate trays are at rightar,gles to one another. Above the slotted openings are baffle-plates K for breaking the upwardlymoving gas into streams, and between the openings are spraying-pipes l. The liquor accumulated in each tray passes to the inlet side of a pump, the outlet side of which is connected with the corresponding spraying pipes l, so that the liquor is continuously circulated. A separate pump may be used for each chamber, all the pumps being, if desired, mounted on the same rotary shaft; or a single pump may be arranged to operate all the circulating systems. The gas is admitted at e and leaves at u, the uppermost chamber Z being fitted with tubes S and baffle-plates t to cause the issuing gas to deposit entangled liquid, which passes by drain-pipes into the chamber y below. On starting the apparatus, the trays are filled with liquid to the level of the upstanding lips thereon by admitting liquid to the chamber y. The pumps are then started and the gas admitted, the liquid being broken up into spray as it enters each chamber and subsequently collected in a tray beneath for circulation.

Title: Improvements in and relating to the dewatering of materials, especially cellulose and the like on a rotary sieve cylinder
IPC: D21F9/04
Filed: 1938-04-25
Abstract: 510,034. Filters. STRINDLUND, J. April 25, 1938, No. 12380. [Class 46] A method of removing water from materials, especially cellulose, in which a rotary sieve cylinder having a plurality of cells rotates partially immersed in a pulp mixture, is characterised in that each cell at or adjacent the point where it emerges from the mixture is exposed to an internal pressure, whereby the layer of pulp on the cylinder is removed. In the construction shown in Fig. 1, a cylinder provided with cloth or perforated sheet 1 is divided into cells 5, each communicating with a discharge passage 6. During rotation of the cylinder, each passage 6 is brought into communication with discharge water in the interior of the cylinder, substantially at the same time as the associated cell 5 emerges from the pulp mixture, so that water flows through the passage and clears pulp from the cell. In a, further construction shown in Figs. 3 and 4, each cell 5 communicates with a passage 6 which terminates in the interior of the cylinder. The interior is in communication with a chamber 7 provided with a stationary ring 10, which is formed with an opening 11. As each cell submerges, the air in the associated passage 6 is forced into the interior of the cylinder to create a pressure in the chamber 7 and this pressure is communicated to a cell through the opening 11 to loosen the pulp from the cell. Compressed air may also be supplied to the chamber 7 by means of a fan or other device. The de-watered pulp may be transferred to a discharge chamber by means of an apertured suction roller, or two rollers, one a pressure roller and the other an apertured roller. The latter roller may also be a suction roller.
