Abstract: 1468989 Removal of organo-lead compounds from water ASSOCIATED OCTEL CO Ltd 17 Dec 1975 [19 Dee 1974] 54994/74 Heading C1C A process for the removal of water-soluble organo-lead compounds from aqueous media comprises converting the water-soluble organolead compounds into insoluble form, and separating the insoluble lead compounds from the aqueous media, wherein the insoluble lead compounds are separated by adsorption on to activated carbon. Reduction (to cause precipitation) may be carried out in alkaline solution, using an alkali metal borohydride, such as sodium borohydride, in an amount of from 30-50% by weight based on the weight of lead in solution. The water-soluble organo-lead compounds may also be caused to precipitate by reaction in alkaline solution with a molar excess relative to the soluble lead compound of an alkali metal sulphide or an organic compound containing at least one N-C-S group in the molecule, such as dithiocarbamic acid, mercaptobenzothiazole, quinoxaline dithiol, thiourea, thioacetamide or dimercaptothiazole. The precipitant may be used in a molar ratio precipitant : organo-lead compound in the range 5 : 1 to 20 : 1. The process is suitable for removing organolead compounds from aqueous effluents resulting from a lead alkyl manufacturing process, e.g. from the washing of lead alkyl storage or transporation tanks.

Title: Tufting machines and methods for producing terry-like fabrics and fabrics produced thereby
IPC: D05C15/00
Filed: 1966-12-12
Abstract: 1,100,170. Tufting machines; tufted fabrics. SINGER CO. 12 Dec., 1966 [27 Dec., 1965], No. 55468/66. Headings D1G and D1K. A tufting machine comprises a first reciprocating needle for penetrating backing fabric to project a loop of yarn therethrough, a second reciprocating needle for entering the loop of yarn presented by the first needle and projecting a loop of yarn therethrough, and looper means for entering the loop of yarn projected by the second needle and for holding the same while the second needle retracts. As shown, backing fabric F passes between a worksupporting plate 51 and an upper plate 52 carrying a series of fingers 53. A reciprocating needle bar 27, located above plate 51, carries a series of needles 28 the axes of which are substantially normal to plate 51. A reciprocating needle bar 21, located below plate 51, carries a series of needles 22 the axes of which are parallel to plate 51. In operation, a needle 28 carrying yarn Y2 passes on one side of a finger 53 to penetrate the backing fabric. As needle 28 begins to ascend, a needle 22 is advanced to pass between needle 28 and the loop of yarn Y2 thereon, whereby continued ascent of needle 28 leaves said loop on needle 22. When the latter commences its return stroke, a looper 37 enters the loop L1 of yarn Yl thereon to hold loop L1 as needle 22 retracts. After needle 22 has withdrawn from the loop of yarn Y2, a take-up operates on yarn Y2 to tighten said loop about the loop L1. Before needle 28 next descends, the backing fabric is fed and plate 52 is shifted laterally, whereby needle 28 passes on the other side of finger 53 to form an upper loop L2 of yarn Y2 thereover. Finger 53 is formed with a hump 71 adapted to expand the loop L2 as the latter passes off the finger 53, thereby further tightening the loop of yarn Y2 under the fabric upon the loop L1.

Abstract: 1434266 Automatic control of speed and tension MASCHINENFABRIK WIFAG 10 Dec 1973 [11 Dec 1972] 57129/73 Heading G3R In a control system for a moving web, the speed of a roller, driving the web in conjunction with a pinch roller, is rectroactively controlled. The motor has an alternative control according to the web tension error, as sensed by a swing roller around which the web passes. In the emodiment, for control of a paper web to a printing machine, the web drive motor 5 is controlled by the error between the actual motor speed, as measured by tachometer 6, and a desired speed from tachometer 7 that is driven by the printing machine motor. Any error from amplifier 9 passes via switch 10, limiter 11 and amplifier 12 to controller 14, that varies the armature power to motor 5. In response to a command to increase the web speed, switch 10 is, manually or automatically, moved to its alternative position, where motor 5 is controlled by amplifier 18 according to the difference between the actual web tension, as sensed by a dancing roller 4, and a desired tension set on potentiometer 16.
