Filed: 1929-07-06
Abstract: 315,004. Groven, J. H., (Assignee of Soc. Anon. des Ciments Portland Artificiels Belges d'Harmignies). July 6, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Rotary strainers.-The coarser particles of a suspension are separated by straining under pressure, finer particles being retained in the strained liquid. In the case of a rotary strainer arranged for straining inwards the pressure may be due to the liquid level outside the strainer. The strainer 3 is mounted over a receiver 2 to which the suspension is supplied from a pipe 2g through valves 2b delivering on to a plate 2P. Strained liquid is discharged through a channel or channels 3r at one or both ends of the strainer. The cylinder may consist of two layers of gauze, of fine and coarse mesh respectively, supported on longitudinal bars 3g and rings 3
, 3<h>. During rotation the bars 3<g> lilt a portion of the strained liquid and thus flush the strainer. The strainer may also be kept clean by steam, water, or air directed under pressure against the interior or exterior surface. The coarse matter and excess liquid are discharged through valves 2<r> which may be controlled according to the level of the liquid by a float in the vessel or according to the percentage of water in the mixture under treatment or to the rate of revolution of the strainer. The strainer may be rotated by directing the incoming liquid from the valves 2b on to paddles attached to shaft 3a. Paddles may also be provided for stirring the material in the receiver 2. Fine particles of matter discharged with the coarser particles may be recovered by decantation. Reference is made to modified apparatus in which the strainer is divided by a transverse partition into two compartments having gauze of a different mesh, so that the compartments separate products of different qualities which are discharged at opposite ends of the strainer. The invention is stated to be applicable to the treatment of suspensions of chalk, kaolin, talc, coal dust, sand, ores and metallic oxides.

Abstract: 586,075. Rotary heel-breast cutting tools. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Oct. 27, 1944, No. 20923. [Class 17 (i)] [Also in Groups XXII, XXIII and XXIV] The shank 10, Figs. 2, 6, of a rotary tool, such as a cutter 13 for trimming heels for footwear, or a brush or finishing or scouring roll, is movable axially relatively to a rotary driving member 26, Figs. 3, 6, when such member is at rest, until co-operating stop faces 28, and forward face of sleeve 29 position these members relatively for operative coupling, when a face 23 on each of a plurality of latch members 20, all under the influence of centrifugal force exert a wedging action against a co-operating face 52 to cause the stop faces 28, 29 to be thrust firmly together to prevent uncoupling during rotation, while permitting rapid uncoupling by relative axial movement while at rest. The blades 13 of the cutter are clamped between a flange 11 and a collar 12 by a nut 15 adjustable along a screw-thread on the shank 10. Longitudinal grooves 16 on the shank 10 are engaged by axial sliding movement with splines 33 on a centering bush 32 on the driving member or shaft 26 which is splined to a sleeve 43. The shaft 26 has a driving pulley 37 at one end and is mounted in rotary and thrust bearings in a fixed sleeve 46 fast in the machine frame. The three latch members 20 are pivoted on pins 22 in a groove 21 in the collar 12 with their heavier ends outwards. The members 20 may be pressed outwards by light springs 25 (not shown). During relative axial movement of the shank 10 and shaft 26 when inserting the tool, the members 20 first engage an enclosed surface 50 on a sleeve 29 at the open end of the shaft 26 and then the walls 52 of an annular groove of V-section to prevent accidental removal of the tool. Under the action of centrifugal force when the shaft 26 and tool are rotating together the heads of the members 20 are forced outwards into the groove 52 to prevent relative axial movement.

Title: Improvements in or relating to the production of cellulose ethers
IPC: C08B11/00
Filed: 1936-08-04
Abstract: Cellulose ethers of a low degree of etherification which are insoluble in water but soluble in aqueous alkali, are prepared by a process involving the steps of continuously impregnating with a liquid etherifying agent a cellulose pulp sheet which has been previously treated with caustic alkali, continuously subjecting the impregnated sheet to pressure to remove excess of etherifying agent, and allowing the impregnated sheet to undergo reaction. As a modification the cellulose pulp sheet may be impregnated with the etherifying agent and caustic alkali simultaneously.  The impregnation of the sheet with etherifying agent may be carried out by passing the sheet through a bath or spray of such agent and then through squeezing rollers; or by supplying the agent to the squeezing rollers, for example, by spraying the liquid on to one roller or by arranging that this shall dip into a trough, the roller being if necessary, provided with a covering of absorbent material or with an engraved surface.  Aqueous solutions of etherifying agents are conveniently employed, and to them may be added wetting agents; similar additions may be made to the caustic alkali used in the preliminary step.  This preliminary treatment with alkali to produce alkali cellulose may also be conducted as a continuous operation. The further reaction necessary to the etherification of the impregnated sheet may comprise standing at room temperature or at temperatures as high as 150 DEG  C. or as low as 0 DEG  C.  In examples, wood-pulp sheets are treated in the above described manner with solutions of sodium methyl sulphate, sodium chloracetate, dimethyl sulphate, diethyl sulphate, ethylene chlorhydrin, and glyceryl monochlorhydrin, the caustic alkali being contained in the solution of the etherifying agent or the cellulose sheets being first converted into alkali cellulose.  The Specification as open to inspection under Sect. 91 refers to the production of cellulose ethers in general; and it includes examples of the use of propylene oxide as the etherification reagent to give a product soluble in water, and of benzyl chloride to give a product insoluble in all solvents and somewhat water repellent.  This subject-matter does not appear in the Specification as accepted.

Filed: 1945-08-24
Abstract: 600,290. Pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. Aug. 24, 1945, No. 21829. Convention date, Nov. 23, 1943. [Class 40 (v)] For blocking a signal pulse amplifier in the intervals between desired pulses, means are provided, responsive to each pulse, to produce a blocking pulse of duration equal to at least a major portion of the interval. In one embodiment, pulses from input 12, Fig. 1, pass through a mixer 10 to demodulator 13 and also to the blocking wave generator 15. The latter comprises an amplifier-clipper stage 18 and a coupling valve 16 from which negative-going output pulses are applied to a tunable resonant circuit 22 adjusted so that one half of its natural period is equal to the time interval to be blocked. The circuit is shock-excited by the pulse 30 ... 32, Fig. 2, and produces one half oscillation 26, subsequent parts of the wave being damped out by diode 24 across the resonant circuit. The undulation 26 is fed to a limit clipper 34 set at the level 33, Fig. 2, the output of which 'passes to a known type of pulse shaper 36 to provide the rectangular blocking pulse 26a which is applied to the mixer 10. Interfering pulses 40, 41 and noise are thus prevented from reaching the demodulator 13 to which is applied the pulse train d, Fig. 2. In a second embodiment, Figs. 3 ... 6 (not shown), the pulses of each channel of a train of interlaced channel pulses in a multiplex system are selected by a similar blocking wave generator. The pulses applied thereto are first shaped as described in Specification 600,284 to eliminate the shock-excitation effect of one of the pulse edges, and thereby produce a blocking undulation of greater amplitude. Specification 600.244 also is referred to.
