Title: Improvements in the purification of carbon black
IPC: C01B31/00
Filed: 1929-10-10
Abstract: Carbon black, especially that obtained by the reaction of chlorine or chlorinated hydrocarbons with hydrocarbons as described in Specifications 317,165, [Class 90, Non-metallic elements], and 343,676, is freed from volatile impurities by maintaining it in dispersion in a suitable gas at temperatures from below 150 DEG  C. to 900 DEG  C. according to the gas employed.  The gases specified are air, nitrogen, carbon dioxide, carbon monoxide, superheated steam, hydrogen, coal gas, coke oven gas or natural gas.  The temperature should be below about 150 DEG  C. for gases containing free oxygen, below about 500 DEG  C. for gases containing combined oxygen and below 900 DEG  C. for gases containing no oxygen.  The carbon may be drawn from a hopper by an injector worked by the preheated gases, the intimate mixture of carbon and gas passing into a heated coil or vessel and the carbon being finally removed by filtration using porous alundum slabs.  A heated vertical tube is preferably substituted for the coil or vessel, the suspension passing up it at a velocity exceeding the rate of settling of the carbon particles.  According to an example, carbon black containing moisture and hydrogen chloride is mixed with carbon dioxide at 300 DEG  C. and passed through a silica coil at 500 DEG  C., the time of contact being 0,8 seconds.  The carbon separated on an alundum filter was free from the above impurities.  Specification 344,227, [Group XXVIII], is referred to.

Abstract: 1513819 Core and effect yarn; bulking yarns by turbulent flow AKZO NV 23 July 1975 [27 July 1974] 30783/75 Headings D1F and D1W A doupioni like fancy yarn 20 is produced from a textured base filament 5' and a textured or non textured effect filament 3 by blow nozzle 15 which operates under a blowing medium pressure which alternates between a fixed low (non-zero) value and a fixed higher value, the nozzle exerting a suction and plaiting effect, the base filament 5' being delivered under a relatively high uniform tension, the effect filament being delivered under a relatively low tension when the blowing pressure is low and substantially without tension when the blowing pressure is high. Preferably the blowing medium is ambient temperature air although heated air or saturated or unsaturated steam may be used to obtain shrinkage or fixing. Air line 17 may supply air at a pressure of 4 to 5 atmospheres and line 18 supplies air at 0.5 to 2 atmospheres, filament brake 6 being activated when the lower pressure line is connected. Alternatively a single variable pressure valve may be used. Interlacing occurs under both pressures; the higher pressure sucks in long lengths of yarn 3 and forms it into loops and kinks about yarn 5'. Pressure alterations may be at regular or irregular intervals. Effect lengths of 15 to 40cm separated by intervals of 1.2 to 12 metres are preferred. The process speed is 80 to 600 m/min. Base filament is overfeed by 2.5 to 3.5% at a tension of 0.025 to 0.04 g/dtex for a total tension of 6 to 10g. As shown a stretched base filament 5 passes through heater 11 and a friction or twisting tube 12 before entering blow nozzle 15. Alternatively, freshly spun base filament 5 may be stretched between delivery units 9, 13 or between delivery unit 9 and an additional delivery unit inserted between unit 9 and heater 11.

Title: Throttle
IPC: G05D7/01
Filed: 1975-07-24
Abstract: 1488205 Fluid regulation UKRAIN NI INST STANKOV I INSTRUMENTOV 24 July 1975 30963/75 Heading G3H [Also in Division F2] A throttle device comprises a stationary housing 1, a rotor 2, and an insert 6 spaced from the rotor by a small clearance 7 to define therewith a restricted flow-path 'A' between inlet and outlet ports (not shown) in the housing. In use the rotor is driven by a reversible motor 9, whereby the flow rate along the flow-path 'A' is dependant on the speed and direction of rotation of the rotor. The insert is made of a material having a higher coefficient of thermal expansion than that of the housing material so that it automatically adjusts the clearance 7 in accordance with temperature changes of the controlled liquid flow and thus avoids changes in flow-rate due to the consequent changes in the viscosity of the liquid. The device may have several inserts spaced concentrically about drive-shaft 8 and each defining a respective flow-path with a common rotor, Figs. 4 to 6 (not shown). A plurality of inserts may be located on each side of a common rotor, Fig. 7 (not shown). The flow along the respective paths may be in parallel or the paths may be inter-connected for series flow. In another embodiment, Fig. 1 (not shown), the insert almost completely surrounds the peripheral surface of the rotor to define the restricted flow-path ('A'). Various formulae are given for calculating the clearance 7 and for determining the length 'S' of the insert.

Abstract: 825,120. Aircraft ventilators. LUNDY MANUFACTURING CORPORATION. Oct. 4, 1957, No. 31086/57. Class 137 A combination fan, valve, and duct structure comprises a cylindrical duct 12, a fan element 14, and a valve element 16 substantially centrally disposed within said duct, said valve element including a plurality of movable blades 56 having first and second positions, said blades in the first expanded position thereof acting to contact the inner surface of said duct to completely seal same, and in the second contracted position to lie in disengaged position with respect to said duct to define an annular opening with said duct through which air may pass, and means for opening and closing said valve upon the starting and stopping of said fan. As shown, motor 104 drives shaft 103 and gear 102 which meshes with gear 105 which in turn meshes with internal ring gear 108 which is capable of rotation on its needle bearings 109. From the ring gear 108 the drive to the fan is communicated to gears 111 and 48 which latter is integral with fan shaft 45. When the motor is started the torque ring 108 upon gear 111 is made to turn its pivot pin 74 through an arc about the axis of the shaft 45, rotating with it valve ring 52 and putting valve-closing spring 54 under tension. The movement of pin 74 is limited by an arcuate slot 114. When motor 104 ceases to drive the fan the torque of spring 54 restores valve ring 52 to its original position and closes valve 16. This arrangement is particularly suited for use in aircraft where a single control for both motor and valve can replace individual controls.
