Title: Improvements in or relating to the balancing of the resistances of mass-resistors
IPC: H01B1/24
Filed: 1938-05-27
Abstract: 515,682. Electric resistances. SHEVLIN, J. T. (Siemens & Halske Akt.-Ges.). May 27, 1938. No. 31162/37. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 13, 1938] [Class 37] The invention relates to " mass resistors " consisting of a mixture of conductive and, or, semi-conductive particles, e.g., metal powder and, or, carbon, and non-conducting hardenable binding agents such as varnishes or synthetic resins. The mixture is normallv moulded to the desired shape and then subjected, preferably under pressure, to heat treatment during which a stable resistance value is attained. The resistances of some of such resistors, which are mass produced, do not fall within allowable tolerance values, and, according to the invention, these are subjected to a further heat treatment at a temperature exceeding the manufacturing temperature to alter their resistance. The nature and duration of this subsequent heat treatment is found by experiment and it may alter the resistance values positively or negatively according to the constituents of the resistors. An example is given in the Specification.

Abstract: <PICT:0755913/III/1> <PICT:0755913/III/2> Apparatus for the production of dispersions, suspensions or emulsions comprises a plurality of series of primary successive dispersing systems, each series being arranged on relatively rotatable surfaces between which the material to be treated flows, and streams of material from the series of systems being impacted against one another so as to mix and have a disintegrating action.  As shown in Fig. 1, the apparatus comprises a double cone 1 rotatable within a casing 2a, 2b.  Teeth are provided on the outside of the double cone and on the inner surface of the casing. Material to be treated enters at 28a and 28b and, after passing between the teeth, flows through horizontal annular gaps formed with cavities 15, 151 and then through narrow gaps 16, 161.  Finally the two streams impinge on one another in the annular gap 27a, 27b and leave the apparatus.  In a modification, Fig. 4, a single conical rotor 101 formed with teeth on both sides is arraged between stators 102a, 102b.  In a further modification (Fig. 3, not shown) the gap and cavity systems 15, 151, 16, 161 are omitted and the gap system 27a, 27b is of nozzle-shaped cross-section.  The apparatus may be immersed in a liquid to be treated so that a continuous circulation of the liquid takes place.  The rotatable cone may be driven via a shaft 13, Fig. 1, or 113, Fig. 4, by a motor above the level of the liquid; compressed air may be supplied to the casing surrounding the shaft in order to prevent liquid or spray reaching the motor. Alternatively (Fig. 10, not shown), the motor may be below a glass vessel through the base of which the driving shaft passes.

Patent GB-843604-A (GB)
Title: Improvements in and relating to electric protective switches
IPC: H01H73/30
Filed: 1956-10-17
Abstract: 843,604. Electrically tripped (or released) switches. IGRANIC ELECTRIC CO. Ltd. Oct. 17, 1956 [Oct. 17, 1955], No. 31601/56. Class 38 (5). A switch tripping mechanism has a heater and two thermally-responsive elements disposed so as to be heated thereby with the first element acting to move the heater and the second element relative to one another, and the second element acting to trip the switch. As applied to a switch similar to that described in U.S.A. Specification 2,673,268, a longitudinallyslidable trip-bar 16 is slotted at 94 for lostmotion engagement by a spring 56 which is normally prevented from moving the bar by its engagement in a toothed wheel 84. The wheel 84 is mounted on the end of an inner part 76 of the second thermal element comprising parts 70, 76 coupled by solder 78. The part 70 is in the form of a sleeve which is press-fitted in an opening 74 in the first thermal element which is a bimetal plate 50 with its edges held in grooves 62, 64 in casing 12. The heating coil 54 surrounds the second element so as to heat it and also heat the bimetal so that its centre moves upward moving the second element further into the coil. When the solder 78 melts, the wheel 84 can move to allow the spring 56 to move the bar 16 to the left, Fig. 1). This moves a lever 24 clockwise about its pivot on a carrier 26 against the bias of a compression spring 27 so that bridging contacts 22 carried by the lever 24 unlatch from fixed contacts (not shown), and a spring 34 moves a push-button 28 attached to the carrier 26, lever 24 and contacts 22 upward to a position where the contacts 22 engage stops or auxiliary contacts (not shown). To reset the switch the button 28 is pressed and a finger 38 on the carrier 26 rocks a member 36 so that a projection thereon engaging a notch 32 in the bar 16 moves the bar to the right with consequential anticlockwise movement of the lever 24 acted upon by the spring 27. When the button 28 is released the contacts latch on to the fixed contacts. The spring 56 is carried on legs 86, 88 of a member 72 which is located by pressed-out projections 92 engaging in holes in the bimetal plate 50. Alternatively the bimetal plate may move the solder element away from the heater and each thermal element may be of other known form, e.g. bellows.

Abstract: 936,178. Lap-forming machines; drafting arrangements. COTTON, SILK & MANMADE FIBRES RESEARCH ASSOCIATION. Oct. 6, 1959 [Oct. 7, 1958], No. 31912/58. Classes 120 (1) and 120 (2). [Also in Group XXXV] In a process for spinning textile yarns, a property is measured before processing takes place in a machine so as to control the machine to correct for short-term fluctuations in the property and the property is measured after processing so as to control the machine to compensate for fluctuations in the property which are long term relative to the processing time. As shown, Fig. 1, cotton is fed at a constant rate from a feed lattice 20 via a pedal roller 21, to a scutcher comprising a beater 11, a top cage 12, a bottom cage 13, calender rollers 14-17 and lap rollers 18, 19. The thickness of the cotton passing over the pedal-roller is measured by a pedal assembly pivoted at a knife-rail 23. The pedal assembly, through links 22, 24 is coupled to a lever 25 pivoted about a nut 26 connected to a bell-crank 28 actuating a plunger 29 of a valve 30. Variation in the thickness of the cotton is compensated by the valve varying the speed of an hydraulic motor 31 driving the pedal roller 21 through a worm and wheel 34, 35. The motor is supplied with fluid from a tank 32 by a pump 32. The output of a detector 36, responsive to the position of the calender roll 14, is dependent on the thickness of the processed cotton and through an amplifier 37a energizes a servomotor 37b which through a gear-box 37c and a worm and wheel 38, 40 drives a screw 41 to position the nut 26, pivoting lever 25, so as to correct longterm fluctuations in the thickness of cotton delivered by the machine. In a modification, the pedal roller is driven via a continuously variable gear from the calender rolls, the pedal assembly varying the gear ratio. In a drafting machine, Fig. 3, comprising front rollers 59, 60 back rollers 47, 48 and measuring rollers 49, 50, the output of a detector 36, responsive to the movement of the roller 59, through a time delay unit 62 and amplifier 63 controls an actuator 64 varying the ratio of a gear 55, 56 through a link 70. A pivot 71 of the link 70 is positioned in dependence on the relationship between the output of a detector 65 and a reference signal 67 by a servomotor 68 through an amplifier 66.

Title: Improvements in or relating to a carbon black separating and conveying system and process of collecting same
IPC: B01D51/02
Filed: 1952-12-19
Abstract: In a furnace process for the production of carbon black where the black is agglomerated and separated from the hot furnace gases in a plurality of dry separators the black separated in the separators is <PICT:0742187/III/1> collected and conveyed to a central collector by a portion of the hot furnace gases before or after some or all of the black has been separated therefrom.  The hot effluent of gas, water vapour and suspended carbon black from furnace 2 may be cooled in quench section 6 equipped with a water jacket and direct water spray 7 and passes to discharge conduit 13, where it may be further directly or indirectly cooled at 12.  In passing along discharge conduit 13, the effluent passes through electric precipitator 16, cyclones 17, 18, 19, and bag filter 21, where carbon black is collected before reaching outlet 14.  Some effluent at about 210 DEG F. say 475 DEG F. is withdrawn through pipe 38 to pipe 31 and is pumped by 32 to collect the carbon black flowing from separators 16-19 and 21, through star valves 22 and outlet conduits 23, 24 and 26-28, and carry it to one or more dry separators 33, 34 where the carbon black is again separated and passes through surge tank 49 and micropulverizers 51 to collection.  The gas from separators 33, 34 may be recycled through pump 32 after a sufficient amount has been removed through bleed conduit 41 to compensate for hot gases added through 38 to maintain the temperature above the dew point say 175 DEG F.  The gas from bleed conduit 41 may be passed to conduit 13 or vented at 46.  Sonic separators or wet separators may also be used in the system but in the case of wet separators the carbon black is not collected therefrom by gas, but the resultant slurry may be passed to the spray 7.  The preferred arrangement is shown but the effluent gas may be withdrawn at any point between the furnace 2 and the outlet 14, while the bleed conduit may be connected to any point of conduit 13 upstream of at least one separator.  The conduit 31 should afford a continuous cycle but may be used as a once through system by valve 36.  The pump 32 may be in any position in conduit 31.
