Title: Improvements in or relating to machines for winding yarn, thread or the like
IPC: B65H63/036
Filed: 1928-07-23
Abstract: 311,263. Universal Winding Go., (Assignees of Swanson, E. R.). May 8, 1928, [Convention date]. Winding machines; stop-motions.-In a drum winding-machine, wherein to arrest its rotation the yarn or like package C, Figs. 1, 2 and 3, is separated from the driving drum 5 and a brake applied approximately simultaneously to - the package, a brake-drum 50 is coupled to the winding-spindle 20 and is engaged by brakeband 56, an intermediate member 70 being moved firstly to apply the brake and secondly to move the winding-spindle support 30 and lift the package C. The lever 70 has lost motion relatively - to the package support 21, the lost motion being utilised for applying the braking action, after which the members 21, 70 move bodily to lift the package C. The stop-motion which operates on breakage of the yarn or on completion of the winding is of the type described in Specification 283,546. The package is wound on a tube T supported on the winding-spindle 20, Fig. 4. which is carried on a support 30 on the arm 21 pivoted at 22. The butt end of the spindle 20 is formed with an enlarged bearing 45 on which is rotatively mounted a flanged disc 50 constituting the brake-drum. The disc 50 is formed with radial splines 51 which engage a cross-slot t in the tube T, and with a flanged rim 55 the interior of which is adapted to be engaged by a brake-band 56 supported at 57 on a pin 58 and having a parallel-sided opening 60 whereby it may be expanded by the cam-portion 62 of a pin 61 adapted to be moved by the member 70 through a crank arm 65 carrying a pin 67 provided with an eccentric bushing 68, the bushing 68 engaging a fork 73 of the lever 70 which is pivoted at 72 on the member 21. The main element of the lifting-means is a rockable rod 87 to which is secured a lever 88 formed with arms 90, 97 under the control of a spring 91 and carrying the spring-controlled lifting-pawl 98 engaging the ratchet 100 which depends from the lever 70. The yarn y is wound on the tube T by the traversing-guide 11 and as the package C grows the arm 21 swings upwardly about the pivot 22, the quadrant 83 riding past the dog 84 and the ratchet 100 past the pawl 98. On the actuation of the stop-motion, the spring 91 turns the lever 88 clockwise (Fig. 8) whereupon the pawl 98 forces the ratchet 100 upwardly to lift the package C off the drum 5. Firstly, however, the pawl 98 rocks the lever 70 and depresses the brake-arm 65 to expand the brake-band 56 and stop the rotation of the package C. The bush 68 may be adjusted on the stud 67 to ensure that the brake is applied simultaneously with the lifting of the package. The brake is released manually to piece the broken end or to turn the package on the spindle 20 by means of a lever 77 secured to the main carrier 21 and provided with a flat cam-plate 76 engaging an opening 75 in the arm 74 of the lever 70. To doff the wound package the spindle 20 is swung forwardly. the crank pin 67 being thereby removed from the slot 73 and the brake released.

Title: Improvements in and relating to electric motor control systems
IPC: H02P29/00
Filed: 1929-07-11
Abstract: 334,994. British Thomson-Houston Co., Ltd., and Green, W. B. July 11, 1929. Regulation, automatic; boosting; equali"ing load on generator.-A motor 1, provided with a flywheel and used for driving a rolling-mill, is controlled so that it runs at full speed until the load-current reaches a predetermined limit, and thereupon its field 2 is strengthened so that it slows down at such a rate that the energy derived from the flywheel assists the load current and keeps the latter within the limit. When the current reaches said limit, a coil 11 operates a relay 8 causing a differentially wound relay 7 to short circuit resistance 6 in the field circuit of a booster 3, the armature of which is in series with the field 2. An antihunting coil 12 is associated with the coil 11 and causes the relay 8 to vibrate at such a rate as to keep the loadcurrent constant. As a transient peak load followed by a sustained full load would cause strengthening of the field 2 but no subsequent weakening so as to allow of return to full speed, the setting of the relay 8 is slowly increased by the action of a magnet 14 and a strong dash-pot 15, the magnet being energized by a relay 16 whenever the field 2 is strengthened. Specifications 3739/07, [Class 35, Dynamo-electric generators &c.], and 3588/09, [Class 80 (i), Gearing, Belt &c.], are referred to.
Patent GB-240424-A (GB)
Title: An improved process and apparatus for the production of pigments from sulphide ores
IPC: C09C1/14
Filed: 1925-08-26
Abstract: 240,424. Kendall, S. W. Sept. 24, 1924, [Convention date]. Pigments. - In the manufacture of pigments comprising sulphates from sulphide ores, particularly lead ores, by heating the ores to vaporize the sulphides without oxidizing them, as for instance in a reducing atmosphere, and oxidizing the sulphides to sulphates, the oxidized fume is chilled by liquid atomized thereinto in limited quantity such that it becomes practically completely vaporized, after which the precipitated sulphates are filtered from the products of combustion in a substantially dry state. Jakna or other sulphide ores are fed by the elevator 2 and worm conveyer 3, Fig. 1, to a rotating sprinkler 4 and distributed over a coke-bed 9 in a furnace 10. The sulphide vapours pass into the oxidizing chamber 12 where they are mingled with cold air entering through adjustable openings 13, whence the oxidized vapours immediately pass to the cooling chamber 14 to cool them below their dissociation temperature. The vapours are chilled by water &c. sprayed by atomizers 15, and pass between water cooled cheeks 16. The sulphate which condenses is removed by doors 24, and a worm conveyer 21, any low grade material being returned to the furnace for retreatment. The fume, comprising fine divided sulphate and combustion gases passes through a conduit 25, Fig. 3, into a space 27a, and thence upwards into the flannel &c. filter bags 28, where the solid material is filtered out, the gases passing into a conduit 28a. The current of gas &c. is maintained throughout the apparatus by a suction fan 29. The bags 28 may be shaken by a handle 34 operating a suspension bar 33, the solid material being removed by scraper conveyers 35 and a worm conveyer 36. The filter chamber may be divided into sections as shown in Fig. 2, each provided with a valve 31. The characteristics of the product. may be varied by the injection of reagents through atomizers 15. Thus, sulphuric acid vapour may be injected to obtain a practically neutral lead sulphate instead of the basic one normally produced from lead sulphide ores. Colours such as a water suspension of ultramarine may be injected to form a product analogous to a lake on a lead base. Separate, atomizers may be used for the reagents if required, and they may be introduced into the combustion or oxidizing chambers. Steam may be injected by nozzles 40, Fig. 1, to prevent formation of sulphites. A particularly suitable pigmentary product which may be obtained has the formula (PbSO4)14 PbO.

IPC: D21C5/02
Filed: 1964-05-25
Abstract: Waste paper is deinked by treating it, preferably at room temperature, with a non-ionic surface-active agent and a polyol. The surface-active agent is of the formula:  <FORM:1081913/D1-D2/1> where R is the aryloxy residue of an alkylphenol in which the total number of carbon atoms is between 7 and 30, R1 and R2 are each hydrogen or alkyl, and n is from 2 to 100; examples are the ethylene oxide adducts of nonylphenol and dodecylphenol.  The polyol is a compound having more than one hydroxyl group, each of which is attached to a separate carbon atom of an aliphatic skeleton; examples are glycols, glycerol, pentacrythritol, trimethylolethane, trimethylolpropane, 1,2,6-hexantriol, sorbitol, isositol and mixtures of these.  An alkali or alkaline salt may also be present; examples are sodium hydroxide, potassium hydroxide and soda ash.  Water may be first placed in a pulper and the active deinking agents then added.  The waste paper is then added; it may be but need not be shredded beforehand but is preferably added dry.  The contents of the pulper are agitated until they are defibred, then dropped to a chest and diluted.  The pulp is then washed, thickened, acidified, e.g. with alum, sulphuric acid or SO2, thickened and formed into a web.  It may be bleached after acidification.

Title: Improved method of making porous metal articles
IPC: B22F3/11
Filed: 1950-09-01
Abstract: 687,598. Powder metallurgy. GENERAL MOTORS CORPORATION. Sept. 1, 1950 [Sept. 20, 1949], No. 21577/50. Class 83 (iv). [Also in Group V] A method of making a porous metal article having a groove therein comprises briquetting a ring containing heatvaporizable material and having a contour of the groove to be formed of larger dimension in the direction of pressure application, placing the ring with metal powder in a die, compressing the powder under pressures substantially higher than the briquetting pressure used in making the ring and sintering the article so formed which volatilizes the heat-vaporizable material and produces a groove in the article. For forming a bush having an external groove a die 30 is used having a pilot rod 34 passing through the bottom wall 36 thereof and co-operating with a punch 38 having a guide aperture 40 for the rod 34. A ring of briquetted heat-vaporizable material 44 is placed in metal powder 42 in the die and the powder is compressed at a pressure between 10,000 and 100,000 pounds per square inch. The briquette is removed from the die and sintered at temperatures appropriate for the metal powder used, e.g. 1500 ‹ to 1800‹ F for copper, tin, or bronze mixtures, 2000‹ to 2200‹ F. for iron mixtures, 1900‹ to 2050‹ F. for copper nickel mixtures. This heat treatment volatilizes the ring 44 so forming a groove 46 in the briquette. The porosity adjacent the groove may be varied by controlling the initial briquetting pressure of the ring 44 which may be 5000 pounds per square inch. The ring may be made of graphite with a metal stearate; a metal stearate per se; stearic acid with a small addition of metal powder and graphite; metal stearate with graphite; zinc stearate or other metal stearates or combinations thereof; a waxy substance such as polymerized ethylene glycol or methylene bis-stearamide with or without a metal stearate or combinations of said waxy substances; salicylic acid; stearic acid; processed wood, wood flour and/or lignin with any of the waxes, stearates or binders; and inert fillers with resin binders such as phenolic moulding powders. A lubricant, such as zinc stearates, is included in the ring. The portions of the article adjacent the groove may be impregnated with another metal, if desired, by including such metal in the ring composition, e.g. in a bronze article of 95 per cent copper and 5 per cent tin, the use of a ring including bronze powder of 60 per cent copper and 40 per cent tin will change the tin percentage in the sintered article adjacent the groove. Specification 558,672, [Group V], is referred to.
