Title: Method for the treatment of siliceous material
IPC: C01B33/18
Filed: 1957-12-20
Abstract: <PICT:0883272/III/1> The wet solid obtained by filtering an aqueous slurry of hydrated siliceous material, e.g. silica or calcium silicate, which has been precipitated from aqueous solution, is dried by heating with agitation so as to drive off a portion of the water content as steam together with entrained partially dried siliceous material, some or all of the entrained siliceous material being separated from the steam and admixed with the wet solid before or during drying.  Precipitated silica may have a specific surface area of more than 95 sq. m/gm, may be in the form of filterable aggregates of ultimate particles having an average particle size below 0,1 micron, and may contain 8-25%, e.g. 15%, of silica.  From 20 to 90% of the silica may be entrained on drying.  The entrained silica may contain 20-50%, e.g. 40%, of free water.  At least one part of partially dried silica may be mixed with 10 parts of wet solid.  The temperature of heating may be 100-200 DEG C.  A product containing 2-10% of free water and 2-10% of combined water may be produced. From 0,05 to 1% of a quaternary ammonium halide containing two or three methyl groups and one or two other alkyl groups, respectively, and containing 8-18 carbon atoms, may be added to a slurry containing 5-25 gm./l. of silica to aid filtration.  Commercial mixtures of quaternary ammonium chlorides are specified.  As shown, a silica slurry is produced in reactor 1, is diluted to a concentration of 10 gm./l. of silica and is treated with 0,2-0,3 gm./l. of a mixture of quaternary ammonium chlorides.  The resulting slurry is passed at a rate of 1 gal./min. via a storage tank 2 and line 3 to a settling tank 4, where it is mixed with clear liquor which overflows from a second settling tank 7 via line 5 at a rate of 5 vols. of liquor per 1 vol. of slurry.  The settled slurry is pumped via line 6 to the second settling tank 7, where it is mixed with clear liquor which overflows from a third settling tank 10 via line 8.  The settled slurry is pumped via line 9 to the third settling tank 10, where it is mixed with hot water from line 11, which is produced by passing cold water from line 12 through a scrubber 13 in countercurrent to steam from line 14, and sufficient 3,5N aqueous hydrochloric acid via line 15 to reduce the pH to 5.  The settled slurry, which contains 1,5 gm./l. of sodium chloride, is passed via line 16 to a filter wheel 17, and the filtered silica is passed via a belt conveyer 18 and a screw conveyer 19 to a steam heated rotary dryer 20.  Product silica in granular form is removed via line 21, while steam and entrained silica is passed via line 22 to a cyclone separator 23. Steam is passed from the separator via line 14 to the scrubber 13, while separated silica is recycled via line 24 to the belt conveyer 18.  Specifications 756,857 and 774,586 are referred to.

Abstract: 1,108,717. Telegraphy. SIEMENS A.G. 13 Sept., 1966 [14 Sept., 1965], No. 40853/66. Heading H4P. A telegraph system comprises means at a main exchange for testing the distortion on lines leading from it to a second exchange and on lines from the second exchange to subscribers. The main exchange B first sets up a connection over AVL1a to an automatic responder AGc at exchange C and sends a message of preset distortion. A serial-parallel converter SPU in the responder will pass the data to a store SP only if the preset distortion plus the distortion caused by AVL1a is less than a given amount. When the store is full it is read out via the converter, and is passed without distortion to AVL1b. At the exchange B the received signals are checked to determine the distortion of AVL1b. If the degree of distortion is satisfactory exchange B now selects a subscriber via exchange C and lines Lc. Knowing the distortion of lines AVL1, that of Lc may be found. Subsequently, other inter-exchange lines are tested, e.g. exchange B sets up a connection, via AVL1 and the responder relays RSc, to lines AVL2, so permitting AVL2 to be checked for distortion. The responder AGc may be replaced by a responder comprising relays only as at AGd in exchange D.

[Also in Division D1] In processing a running length of monofilament or multifilament, thermoplastic, e.g. polyester, polypropylene or nylon, yarn 11, which may have been drawn and/or edge or gear crimped and will shrink in length or be permitted a controlled relaxation when heated, e.g. to develop and/or stabilize the crimp, is overfed by 3-30% through an elongated conduit 12 in the form of a series of compressed coiled turns lined with a low friction material such as polytetrafluoroethylene, nylon or glass, which it enters at a velocity greater than that at which it leaves at 13. Gas is preheated by its flow through a tube, also in the form of a series of coiled turns, located in close proximity to both a circular heating element and the coils of the conduit. The preheated and compressed gas is delivered to the conduit through which it flows in the direction of yarn travel and the yarn is heated thereby to a temperature of 200- 500‹ F. during its passage therethrough over a period of 0À5-10 seconds. The gas may be delivered by an aspirator 10 or a capillary tube as described in Specification 991,771. The aspirator shown in Fig. 9 comprises a portion 91 fitted into a bore 94 in portion 90 so that compressed gas, when it enters through delivery slots 97 around the forward portion 95, is forced through a bore 93 thereby creating a Venturi effect in the vicinity of portion 95 so that suction is created in the area thereof and the yarn is conveyed thereby through bores 100 and 93 and leaves, in twist free condition, through a flared portion 92 in the direction of movement of the gas to the heating apparatus.

Abstract: 1,164,401. Mechanical interrupters. E. W. BLISS CO. 12 Sept., 1967 [19 Sept., 1966], No. 41556/67. Heading H1N. A repeating cycle time switch having independently adjustable "on" and "off" periods comprises a pointer C continuously oscillated between pointers A and B and arranged to actuate switch contacts as the pointer C passes through the datum position shown. Pointers A and B are manually settable against "on" and "off" scales 14 and 16, respectively, by means of knobs 20 and 24, and thus each determines the duration of the respective "on" or "off" period without interfering with the other. The pointer C is secured to one end of a shaft 26 (Fig. 5) about which a timing plate E is free to revolve. A synchronous motor (64, Fig. 2, not shown) and suitable gearing drives two gearwheels (46 and 54), close to, and coaxial with, timing plate E, in opposite directions and these mesh respectively with two pinions (78 and 80) on shafts 86 journalled in the plate E and also carrying ratchet wheels 82 and 84 (Fig. 5) which thus revolve continuously in opposite directions, as indicated. A pawl 110 is pivoted at X on a bracket 118 attached to plate E and an overcentre spring 116 urges the end 111 into locking engagement with one of the ratchet wheels 82 and 84. A timing control plate G is secured to shaft 26 (and hence to pointer C) and has lugs 112, 114 straddling spring 116 and lugs 106, 108 straddling pawl 110. While pawl 110 is locking wheel 82 (as shown) the plate E, together with control plate G and pointer C, is driven clockwise until pointer C engages a flange on pointer B whereupon control plate G is arrested and lug 114 moves spring 116 overcentre. Lug 106 ensures that pawl 110 frees wheel 82 and snaps over to lock wheel 84, whereupon plate E commences reverse rotation until pointer C is impeded by pointer A and the cycle repeated. Two teeth 164 on plate E co-operate with a Geneva gear on shaft 172 as pointer C passes through its datum position and cause cams on the other end of shaft 172 to actuate two switch units (160, 162, Figs. 2, 3 and 4, not shown) on and off alternately. Coil springs (100, Fig. 6) on the bosses of ratchet wheels 82 and 84 provide sufficient frictional resistance to their reverse rotation to prevent inertial overshoot of plate E when the pawl 110 is released but permit pointers A and B to be reset during operation even to shorter times than that being instantaneously indicated by pointer C.
