Title: Improvements in the manufacture of artificial filaments and similar products
IPC: D01F2/28
Filed: 1931-09-14
Abstract: Artificial filaments and the like of reduced lustre are produced by incorporating with the solution to be spun, a finely divided relatively insoluble tin compound, preferably stannic oxide, stannic phosphate, or stannic oxychloride.  The tin compound is employed in a state of fine subdivision, the particles being preferably of diameter ,1 to 5 microns, and obtained by grinding either dry or in the presence of suitable liquids such as water, oleic acid, linseed, olive or other oil, part of the spinning solution, or with the solvent used in the spinning solution.  Dispersing agents and/or protective colloids may also be present, e.g. Turkey red oil.  Other liquids such as diethylene glycol, heavy white mineral oil, olive, castor or other oils may be added separately to the solution.  After incorporation of the tin compound the spinning solution is preferably thoroughly mixed and passed through a series of filters.  In an example cellulose acetate is dissolved in acetone and to this is added 1 per cent (of the weight of the cellulose acetate) of stannic oxide or phosphate dispersed in water, acetone, or a solution of cellulose acetate dissolved in acetone.  If desired 1-5 per cent of olive oil or diethylene glycol may be added to the solution prior to spinning.  Specification 343,949 is referred to.  The Specification as open to inspection under Sect. 91 also refers to a process whereby the tin compound is incorporated with the filaments or the like after their formation into hanks, fabrics, or other suitable form, by treatment with a dispersion of the tin compound, preferably in presence of a swelling agent for the cellulosic material of which the filaments are composed.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to calculating apparatus
IPC: G06G1/04
Filed: 1949-10-11
Abstract: 680,131. Calculating-apparatus. MACIVER, P. R., MALBY, J. R., and HAYLLAR, J. Sept. 28, 1950 [Oct. 11, 1949], No. 26142/49. Class 106 (i). In a rotatable disc calculator for evaluating a predetermined function of two variables, values of the two variables are represented by systems of intersecting lines A and B on a disc 2, and results are read by means of a cursor 4 against a scale on a companion disc 1 after setting the cursor to the intersection of the appropriate lines A and B. Results of successive evaluations may be added to provide a cumulative result. The calculator shown evaluates the cumulative moment about the centre of gravity of an aircraft of various loads according to their weights and positions. The lines A represent weight values and are duplicated on either side of a line C representing the centre of gravity of the aircraft, whilst the lines B represent position values. The result scale of the disc 1 is likewise duplicated on either side of a centre of gravity line F to show nose-heavy moments D and tailheavy moments E, and a line G thereon shows the out-of-balance moments of the unloaded aircraft. In using the apparatus, the discs are adjusted to bring the lines C and G together, the cursor 4 is adjusted to the intersection of lines A and B corresponding to a first load so that the resulting moment is then shown by the cursor on the scale D or E. The operation is repeated for the second load, but now bringing the line C to the first resulting moment on the scale D or E. Further loads are similarly taken account of so that the cursor finally shows the out-ofbalance moment of the fully-loaded aircraft on the scale D or E according to whether the aircraft is nose or tail heavy. The disc 2 also has a special scale J for taking account of passengers and other loads which can be regarded as of invariable weight and position. The cursor is extended over the rear of the disc 1 which may be marked with a further scale or scales indicating, for example, limiting values for the final moment. Other uses for which the calculator may be designed are costing according to prices and quantities of materials, and estimating a ship's stability when loaded. The discs may be of aluminium alloy, and the scales printed thereon anodically and in contrasting colours.
