Patent GB-342743-A (GB)
Title: Improvements in the manufacture of artificial silk filaments
Filed: 1929-08-09
Abstract: The lustre and softness of artificial silks are modified by incorporating in the spinning solution fine particles of a non-volatile oleaginous material such as heavy white petroleum oil and of a pigment such as titanium dioxide insoluble in the solution and having a particle size less than 0,75 microns, and before spinning passing the solution through at least a portion of the usual filtering system.  By filtering the solution, aggregations of particles are broken up, while the oleaginous material besides acting as a softening agent with respect to the filaments also serves to facilitate the filtering operation.  In the case of nitrocellulose silk, the oil is dissolved in a portion of the alcohol-ether used as solvent, the titanium dioxide pigment is ground with the remainder of the solvent, the nitrocellulose is dissolved by thorough mixing in the solvent so prepared, and the solution obtained is subjected to the filtering operations usual before spinning.  A similar procedure is adopted in the preparation of solutions of cellulose acetate in acetone, the oil being dissolved in a portion of the acetone or in ether.  As an alternative procedure the oil may be mixed with the solution of the cellulose material.  Specifications 243,350, 290,693 297,364, and 339,603, [all in Class 2 (ii), Cellulose &c.], are referred to.

IPC: G05D7/06
Filed: 1965-06-11
Abstract: 1,105,974. Tube mills. POLYSIUS G.m.b.H. 11, June, 1965, No. 24714/65. Heading B2A. [Also in Division G3] The amount of grit separated in a sieve grinding mill, e.g. for cement, and re-fed to the grinder automatically controls the amount of fresh material supplied to the mill so that the total input to the mill is maintained at a value which is automatically varied in response to mill noise to keep the latter between limits. In Fig. 1, the output of a two-chamber mill 1 is transported by a bucket elevator 2 to a sieve 3, grit from which is returned to the mill. Weighing conveyors 4, 5 produce signals respectively dependent on the rate of flow of grit and fresh material to the mill. The sum of these signals is compared with a desired total flow signal 12 and any difference acts through a controller 7 to correct the total flow by automatically adjusting the rate of supply of fresh material. A microphone 6 responsive to noise in the mill produces a signal which, if greater or less than predetermined signals 14, 15, acts to adjust the desired total flow signal 12 to prevent mill noise from getting outside satisfactory limits. In one modification, one of a number of microphones associated with different chambers of a multichamber mill may be selected to effect control. In another modification, each of a number of microphones is effective if the noise it detects is outside predetermined limits. In a third modification, one or more of a number of microphones may vary the limits of another microphone which controls the noise. A signal dependent on the rate of flow of grit may also be derived from the power taken by a motor driving the bucket elevator or the sieve.

Filed: 1939-08-29
Abstract: 535,178. Chlorinating titanium ores. PITTSBURGH PLATE GLASS CO. Aug. 29, 1939, No. 24802. Convention date, June 30. Drawings to Specification. [Class 1 (iii)] In the chlorination of ilmenite or other material containing titanium or iron to produce a mixture of chloride vapours, the major portion of the iron chloride is condensed with a quantity of titanium chloride (preferably at least 15 per cent.) sufficient to ensure the elimination of the major portion of the iron chloride and thus to prevent plugging of the system. The condensed mixture may be heated in the presence of a portion of the uncondensed vapour or of chlorine to re-volatilize the titanium chloride. The heating may be effected in a part of the condenser itself; in this case a long condenser is used in the first part of which the chlorides condense on to a conveyer belt which carries them to the further end of the chamber, where a suitable heating means operates. The residual iron chloride falls to the floor of the chamber and is moved by scrapers to a discharge opening. The invention is particularly applicable to the chlorination process described in Specification 535,179. Specifications 533,378 and 533,379 also are referred to.
