IPC: D04C5/00
Filed: 1919-11-25
Abstract: 159,031. Tomlinson, M. G. Nov. 25, 1919. Bobbins, winding.-In apparatus for winding brass bobbins used in twist lace machines means are provided for automatically bringing the indicator pointer and associated parts to rest when the bobbins have been filled. In a known apparatus the indicating-pointer 21 is mounted on a shaft 17 carrying a clutch member 19 and is brought to rest when the bobbins have been filled to the requisite degree by the disengagement of the clutch 19 from the coacting member 18, which is mounted on a loose sleeve 16 driven by a felt roller over which the bobbin threads pass. According to the present invention, the shaft 17 is moved endways against a spring 25 by the movement of an arm 27 over a fixed edge cam 28, the arm 27 being pivoted at 31 to the end of a shaft 26, on which is mounted a toothed quadrant 23 gearing with a pinion 22 on the shaft 17. A plate or projection 30 on the quadrant bears on the rear face of the pinion 22 and enables the endways movement of the shaft 26 to be transmitted to the shaft 17 through a collar 24. The lower end 33 of the arm 27 bears on a flat vertical plate 34, and the upper end is formed as a handle by means of which the parts can be re-set. The winding-shaft may be brought to rest simultaneously with the disconnection of the parts 18, 19.

Drawings to Specification. [Class 97 (iii).] Relates to improvements in a grading machine of the two pantograph type wherein relative movements are adapted to take place between the model and a member for contacting with the edge of the model in directions mutually perpendicular to each other and in parallel planes, for example of the type described in Specification 335,200, [Class 97 (iii), Thermometers &c.]. To enable a cut-out portion of the model to be reproduced on the pattern at a graded distance in a given direction from the edge but having dimensions in this direction equal to that of the. cut-out portion of the model, means are provided to render the pantographic mechanism inoperative without disturbing the relative positions of the members connected. For example, in a grading machine in which a combined model and workpiece holder is connected to a model guide by pantograph levers when it is desired to suspend operations of a pantograph lever the latter is clamped to the machine frame and its connection with the model holder freed. To enable a portion projecting at an angle from the model to be graded in different proportions along its length and width, the model holder is angularly adjustable so that the length and width of the projection may be made to lie respectively along the perpendicular directions of travel of the holder.

Filed: 1938-10-13
Abstract: 520,152. Artificial filaments etc.; treating textiles with liquids. LEWIS, F. D. Oct. 13, 1938, No. 29631. [Classes 2 (ii) and 15 (ii)] Tinted solid or inflated threads, filaments, , films, monofils, and other articles obtained from cellulose esters or ethers including cellulose acetate have incorporated therewith an unpurified coloured or/and purified white highly refractive, high-boiling halogenated diarylamine having a high melting point preferably above 100‹C. for imparting a diminished lustre to the materials. Chlorine, bromine, or iodine compounds may be used. The halogen compound may be obtained by passage of halogen through the liquid diarylamine, or by halogenation of the diarylamine dissolved in alcohol or other solvent. The halogen compounds used may be odourless or may have a floral aroma. The delustrant may be dispersed in the spinning solution provided it is only sparingly soluble in the acetone or other solvent used, or it may be used in the form of a salt, e.g., an acid-reacting salt which is dispersed in the spinning solution. In this case the salt is decomposed during or subsequently to spinning by an alkaline treatment. The salts may be dispersed alone or together with an acid-reacting salt of a watersoluble amine or amide or with an alkyl or terpenyl sulphate or pyrosulphate of barium or lead. The spinning solution may also contain an oleate of potassium, barium, or lead. Halogenated diphenylamine, ditolylamine or dibenzylamine, or a mixture of polychlor mono- and di-#-naphthyl benzidines, or a tetrachlor methyl diphenylamine may be used. Salts of these compounds with hydrochloric, sulphuric, or tungstic acid may be used. Amide or amine salts which may be used additionally include aniline hydrochloride, guanidine sulphate, aniline hydrogen tartrate or citrate. The alkaline treatment may be effected with bicarbonates, organic carbonates, ethanolic magnesium hydroxide, or aqueous barium hydroxide. The filaments may become inflated when treatment is effected with a carbonate. Tetrabromdiphenylamine, or polychlor-##<SP>1</SP>-dinaphthylamine may be dispersed directly in the solvent employed. In an example, tetrabrom-diphenylamine hydrobromide is dispersed in an acetpne solution of cellulose acetate. The solution is dry spun and the pinkish thread is treated with sodium bicarbonate. In another example, a coloured halogenated diarylamine and a sulphate of a water soluble amide or amine is dispersed in a cellulose ether solution which is then spun into a solution of barium hydroxide. Specification 517,886 is referred to. The Provisional Specification comprises also the use of aryl or aralkyl amides or amines, e.g. diaryl guanidines and dialkyl diaryl ureas as delustring substances.

Title: An improved method for the smelting of ores in shaft furnaces
IPC: C21B5/00
Filed: 1951-12-24
Abstract: In a method of smelting ores, particularly iron ores, in shaft furnaces which are charged at the top and which are provided with blast tuyeres near the bottom, the furnace is charged with briquettes, preferably of egg-shape, comprising fine-grained ore, a reducing agent consisting partly of caking hard coal and partly of non-caking fuel and a binding agent such as lime, clay, marl or pitch, the height of the charge column within the furnace shaft is maintained at 2-6 metres above the tuyere level, the distance between two opposite furnace walls where the tuyeres are disposed is about 1-3 metres, and the charge column is maintained substantially at the selected height during the smelting operation.  The waste gases leaving the furnace shaft are first freed from dust, and then subjected to a condensation process in two stages, a thick tar obtained in the first stage being used as a binding agent for the briquettes which have a volume less than 300 c.c., preferably 40-80 c.c.  The ore may also be supplied in lumps of substantially the same size as the briquettes.  The blast may be heated to about 500 DEG  C. and mixed with oxygen or a cold blast containing additional oxygen may be used.  A typical composition for the briquettes is: 32 per cent non-caking hard coal, 11 per cent caking hard coal, 36.5 per cent iron ore, 14.5 per cent limestone, 2 per cent tar pitch, and 4 per cent thick tar (from the aforementioned condensing stage).  The grain size of the ore and limestone is 0-3 mms. and of the coal 0-5 mms.
