Title: Improvements in Cigarette Filling Machines.
Inventor: LINDELOEF LEONARD
IPC: A24C5/02
Filed: 1916-05-10
Abstract: 106,135. Lindelof, L. May 10, 1916. Cigarette-making machines.-Consists in improvements in machines of the kind wherein a continuously rotating disk 4 is provided with a number of filling-tubes 15, on the ends of which cigarette-paper tubes are threaded and a string of tobacco is introduced into the opposite end of a filling- tube 15 by means of a feed-tube 26 which rotates with the tube 15 during the filling operation and is afterwards returned rapidly to the next filling-tube 15. One feature of the invention consists in providing a supplementary feeding device for the string of tobacco comprising two grooved feed-rollers 37, 38 which enter openings in the wall of the tube 26 and embrace the tobacco from opposite sides. The rollers and feed-tube 26 are carried at one end of a lever 23 pivoted on a shaft 70, the other end of the lever 23 having a roller in contact with a cam 25 on the main drive shaft 5. The rollers 37, 38 are driven from a toothed wheel 42 on the shaft 70 through toothed wheels 39, 40, 41. The wheel 42 is driven from the shaft 5 at the same angular speed as the lever 23 at the springing-back of the supply tube 26 from a filling tube to the following one, with the object of stopping the turning action of the gearwheel 42 on the feed-roller during this return motion. Another feature of the invention consists in making the connexion between the stationary part 43 of the feedapparatus and the tube 26 by means of a movable tube or channel 44 built up of two telescoping sections pressed apart by a spring 45; the tube 44 is rounded at both ends and is inserted in socketlike recesses in the parts 26, 43. For removing the paper tubes filled with tobacco from the tubes 15, a rod or piston 46 movable into the tubes is provided, the reciprocating movement of which is effected by a lever 47 and camgrooved disk 48 secured to the shaft 5. The rod 46 is connected to the lever 47 by a ball-andsocket joint, while its other end slides in a sleeve in an arm 49 on the lever 23.
Patent GB-568047-A (GB)
Title: Improvements in the production of cellulose esters
IPC: C08B3/22
Filed: 1943-04-28
Abstract: Organic esters of cellulose are obtained by esterifying cellulose with an organic acid anhydride in the presence of an acid catalyst, e.g. sulphuric and/or phosphoric acid, and a solvent for the ester, and ripening the primary ester with water in solution in at least two stages, the commencement of each of which is marked by an increase in the amount of water and a decrease in the amount of catalyst present in the solution. Further ripening stages may be effected with increased amounts of water.  The ripening treatment may be carried out at elevated temperatures.  The catalyst content is decreased by neutralizing with a salt or mixture of salts of magnesium, calcium or zinc, e.g. the acetates, or with magnesium, calcium, aluminium, barium, copper, lithium or strontium carbonate, or with zinc oxide or an oxide or hydroxide of aluminium, barium, copper, lithium or strontium.  The neutralizing agent may be added to the solution with the water for ripening or in solution in glacial acetic acid or separately, in powder form.  Cellulose, which may be subjected to a pretreatment with, for example, acetic and/or formic acid in the presence of sulphuric acid, is employed in the form of cotton, cotton linters, wood-pulp, regenerated cellulose, or cellulose material obtained from grass, straw, or husks.  The process is particularly applicable to the manufacture of cellulose acetate, but other esters such as the propionate, butyrate, acetate-propionate and acetate-butyrate may be obtained thereby. The cellulose esters so prepared have a high stability and heat-resistance and have improved moulding properties.  They may be employed for the manufacture of filaments, fibres, moulding compositions, &c.  Numerous examples indicating various ripening treatments are given.

Abstract: 567,007. Shoe stiffenera. BRITISH UNITED SHOE MACHINERY CO., Ltd., and MAcDONALD, D. B. April 29, 1943, No. 6749. [Class 140] A shoe stiffening member comprising a fibrous base charged with nitrocellulose is subjected to treatment at room temperature with a solvent composition to bring it into relatively soft condition to permit forming of the member into the desired shape in the shoe, evaporation subsequently taking place to permit the shaped member to harden, the solvent composition comprising ethyl alcohol and camphor, the ethyl alcohol being present in greater amount by weight than the camphor, and the composition being such that but for the camphor it would not exercise adequate solvent action. From 1¢ to 30 per cent by weight of camphor may be used. The solvent composition may comprise a mixture of in. dustrial methylated spirits and benzene, or a mixture of industrial methylated spirits, petroleum spirit and benzene. Low-boiling solvents (e.g. ethyl acetate or methyl ethyl ketone) may be added. The camphor may be obtained from the celluloid cutting scrap used in the preparation of the nitrocellulose solution. Nitrocellulose - charged counter - blanks may be softened with a composition comprising industrial methylated spirits, petroleum spirit, benzene, butyl acetate, and camphor. Specifications 117,068, 210,168, [both in Class 140], 493,066 and 535,617, [Group VII], are referred to.

Title: Signal transmission systems
IPC: F22B37/42
Filed: 1960-02-26
Abstract: 884,869. Automatic control systems. SUL. ZER FRERES S.A. Feb. 26, 1960 [March 5, 1959], No. 6873/60. Class 38 (4). [Also in Group XXIX] In a signal transmission system only the maximum or minimum signal of a number of signals is normally transmitted but the next signal in order of magnitude is transmitted when the maximum or minimum signal is outside a limiting value. In a steam generator, for example, a number of thermocouples or resistance thermometers may produce electrical signal voltages representative of the temperature at different points of the tubes of a superheater surface. In Fig. 1 such signal voltage U 1 -U 4  are applied through rectifiers 14, which may be of the semi-conductor type, so that a common line 15 is at a voltage corresponding to the highest of the signal voltages, since only the rectifier associated with that voltage will be conductive. The consequent current through this rectifier operates its associated relay 13 so that the highest signal voltage is disconnected from a second common line 17 to which the remaining signal voltages are connected through rectifiers 16 so that line 17 is at a voltage corresponding to the second highest signal voltage. The highest signal voltage is normally transmitted from line 15 through contacts of a relay 18 to a device 12, which may operate to regulate the superheater temperature automatically, e.g. by controlling water injection, but, should the difference between the highest and next highest signal voltages exceed a predetermined value, indicating that the highest signal voltage is the result of a fault in the detector, relay 18 operates to substitute the next highest signal voltage from line 17 to control device 12. In modifications changeover is effected if the difference between the highest signal voltage and the mean of some or all of the signal voltages exceeds a predetermined value, or if the absolute value or rate of change of the highest signal voltage exceeds a predetermined value. The voltages on the common lines may be maintained above a minimum value by a voltage applied through rectifiers. More than one high signal voltage may be rejected. An arrangement involving only fluid-pressure signals with means to ensure smooth changeover is described (see Group XXIX). Applications to the control of temperature of the fuel elements of a nuclear reactor and to the control of pressure are referred to.

Title: Improvements in or relating to the production of microspherical carbon particles
IPC: C01B31/08
Filed: 1951-03-22
Abstract: Spherical carbon particles are produced by decomposing a gaseous suspension of liquified finely-divided carbon-rich material composed of carbohydrates, pitches, or resinous materials; when the starting material is solid it has a particle size of 20-500 microns and when liquid a droplet diameter of 50-200 microns.  The material may be treated for 5-30 seconds at a temperature of 800 DEG -1200 DEG F.  In the apparatus shown, a saturated aqueous solution of molasses is sprayed through nozzle 7 into a stream of hot flue gas, nitrogen, or steam, introduced at 1; carbon microspheres are separated in cyclone 11 and collected at 15; <PICT:0699470/III/1> when powdered carbohydrate is used it is introduced from hopper 17.  In another example powdered cane sugar is blown into the top of a heated quartz tube.  Other suitable starting materials are hydrolyzed starch, petroleum and coal tar pitches, and resin.  The carbon particles may be activated with steam or carbon dioxide, and are useful as heat transfer media, for contacting fluids, as adsorbents for the desulphurization of gases or the removal of unsaturated hydrocarbons from hydrocarbon mixtures, or as catalysts or catalyst carriers in fixed bed or fluidized processes, e.g. the cracking of hydrocarbon oils.
