Title: Improvements in counter current washing processes for granular or similar material
Inventor: ROSE LESLIE
IPC: B03B5/62
Filed: 1960-02-02
Abstract: 928,647. Washing granular materials. KIRKLEES Ltd. April 28, 1961 [Feb. 2, 1960], No. 3581/60. Class 82 (2). Granular materials are washed by a multistage counter-current process according to a method in which, in each washing stage, wash liquid is introduced from below into wash vessels containing the granular material at such a pressure that it not only percolates through the material but also fluidises it and the liquid remains in the vessels in contact with the fluidized material for a predetermined period of time and is then drained away, leaving the granular material within the vessels. The invention has particular application to washing sodium carboxymethyl cellulose with a washing medium of aqueous methanol or aqueous ethanol. Separate stage tanks A are arranged in a ring around a cylindrical tank B, which can be raised and lowered in relation to the tanks A by a cable C. Each tank A is provided with an inner vessel D having a perforated base, into which the granular material is loaded, and the vessels D may also be raised and lowered by a pulley block E which can run on a circular rail E<SP>1</SP>. The tank B is subdivided into segments b, each being associated with a storage tank A, with which it is in communication through a flexible pipe E<SP>2</SP>. Also the stage tanks A are interconnected, each being in communication with the next vessel but one before it through a flexible pipe e<SP>1</SP>. Washing liquor is introduced to a stage vessel through its conical base, underneath the perforations, at a pressure of 1-5 1b. per square inch, or more, fluidises the material, settles, and is allowed to drain into the associated space b; and the cycle may be repeated. The above cycling is performed by raising and lowering the tank B, air displacement being provided for by flexible pipes e<SP>3</SP> connecting the tops of the tanks A to a space above the liquid level in the segments b. At the end of the cycling a valve is operated to disconnect the tank A from its segment b and to connect it to the stage tank A next but one previous, the whole of the liquor being transferredthe reto. The inner vessels A are raised out of their stage tanks at the end of all the stages of the washing operation. The various stops may be controlled by a process timer of known design.

Abstract: 707,554. Copy-milling. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Feb. 15, 1952 [Feb. 15, 1951], No. 3703/51. Class 83 (3) A multiple-spindle vertical milling or drilling machine having compound slides 16, 18 is adapted for copying work-pieces, such as turbine or compressor blades 12, by fitting a cylindrical milling cutter 14 on one spindle and a stylus 13 on the other spindle and by supporting the work and the pattern 11 in a pivoted cradle 7 on a carrier 2 which is movable across the direction of longitudinal traverse of the slide 16 on a baseplate 1 secured to the slide 16 and is biased towards the spindles by springs or by weighted cords on pulleys. In operation, the lateral traverse of the machine is used to bring the carrier 2 towards the spindles until the cutter engages the work and the movement is continued until the carrier moves across the baseplate against the action of the springs or cords sufficiently to give the desired pressure of the tool on the work. A longitudinal traverse is then made to cut a facet on the leading edge of the work and after each traverse the cradle is indexed to present a new facet, either by hand, in which case sufficient friction must be provided to keep the cradle in its angular position, or by a ratchet 15 operated by an adjustable cam plate 20 on the machine head. Adjustable tooth guards 26 on the ratchet determine the starting and stopping positions of the cuts. The pattern and work are mounted so that the pivotal axis of the cradle and the centre of curvature of the leading edge of the blade more or less coincide. The pattern may be chrome-plated to prevent undue wear. Beds and framings.-The cairier is supported on ball-bearings running in races 1b which are of V-section, with the exception of the upper track 2b one side, which is flat topped.
