Abstract: 1,250,277. Crucibles. SWISS ALUMINIUM Ltd. 21 Feb., 1969 [23 Feb., 1968], No. 9568/69. Heading F4B. [Also in Division C7] In a process in which a melt of Al or Mg or Albase or Mg-base alloy is treated in an essentially closed container with a non-metallic agent that is gaseous at the temperature of the melt, the treatment resulting in the escape from the melt of a vapour that condenses to a solid at room temperature, the said vapour is condensed as a solid on a surface within the container above the melt by cooling that surface. Apparatus for the introduction of a gaseous agent is shown in Fig. 1 and comprises crucible 1 containing melt 2. Pipe 3 for the agent passes through cover 4 which is cooled by passage of water through pipe 6. Apparatus is also described for the introduction of (a) solid agent where the agent is contained in a bell with a perforated bottom plate, the bell being lowered into the melt (Fig. 3, not shown); (b) solid or liquid agent where a volatilization chamber for the agent is mounted inside the crucible or other vessel and communicates with the interior of the melt via a tube (Fig. 4, not shown, and, for solid agents only, Fig. 5, not shown). In the modification shown in Fig. 7, molten metal flowing to a continuous casting mould through trough 40 is treated with gas introduced through tube 46 within the container formed by deepened portion 41 of the trough and baffles 42, 43. In further modifications, (1) solid treating agent may be held at the bottom of the crucible or other vessel by a perforated plate on to which the metal is allowed to flow, (2) the agent may be introduced as briquettes, (3) liquid agents may be absorbed by a solid, e.g. kieselguhr, and introduced in this form, (4) solid or liquid agents may be volatilized outside the container and introduced as vapour, and (5) vapour escaping from the melt may be condensed on a coiled pipe, e.g. air-cooled, which passes through the crucible or other vessel (Fig. 6, not shown).

Abstract: 1,266,370. Programmed control of warehousing. TRIAX CO. Aug.26, 1969 [Sept. 19, 1968], No.42466/69. Heading G3N. The position of a load carrier of a warehousing system, employing a rack-type storage structure, is verified to provide a check on the programmed position control. The verification is effected in three alternative ways (1) by duplication of position sensors and selector switches of the primary control system and actuating a storage extractor on coincidence, (2) spot-checking, in response to position sensors, certain positions of the load carrier and preventing actuation of the load carrier, to deliver or pick-up a load, if verification does not occur at the checking positions, and (3) by actuation of an individual address sensor device at each storage location which is checked with the programmed position address before extractor motion can begin. When the position is not verified the load carrier is returned to the starting position.

Abstract: 1290195 Railway systems JERVIS B WEBB CO 1 Jan 1970 [6 Jan 1969] 0047/70 Heading B7L A monorail transportation system or railway, comprises a rail 14, mounted on a planar support 12, and a vehicle 11; the rail has two oppositely facing track surfaces 22, 23, which extend substantially perpendicular to the support and on which are mounted electric conductor bars 18, 19; the vehicle, Fig. 2, has mounted on its frame 26 three wheels 28 which engage the support and may be either fixed or castering, two guide rolls 32, an electrical pick-up assembly 34, which engages the conductor bars, and a driving assembly comprising a motor 40, a drive roll 38 and an idler roll 36, the drive and idler rolls engaging the track surfaces 22, 23 respectively. The motor 40 and a shaft 47 of the drive roll 38 are both mounted on a bracket 45, the latter being mounted on a pivot pin 41 connected to a boss 44 secured to the vehicle frame 26, such that the pivoted axis lies between the shaft 47 and the centre of the motor. This arrangement ensures continued traction when the vehicle traverses curves. Normally the drive roll is urged into engagement with the track surface by a spring 50, mounted in a recess 51 of the boss 44, bearing on a plate 48 attached to the motor base 49. Referring to Fig. 2, if the vehicle travels in the direction of the arrow 59 the centrifugal force exerted on the motor 40 causes it to rotate in a clockwise direction, thus rotating the bracket and urging the drive roll into engagement with the track, the vehicle travels in the direction of the arrow 60, the motor rotates in an anti-clockwise direction, urging the roller away from the track and preventing binding. These pivotal movements are limited by the plate 48 engaging the boss 44. The motor is preferably operable by a relatively low voltage (24 volt D.C.) the current being collected from the conductor bars by the electrical pick-up assembly. This assembly, Figs. 8, 9, preferably comprises a carbon shoe 74 having conductor bar engaging portions 75, 76 and being pivotally mounted at 77 on a bracket 78 of insulating material, the bracket being secured by a pivot pin 79 to a boss 80 on the vehicle frame. A spring 82 is connected to the bracket 78 and to a second boss 83, a lead wire 84 being connected to the shoe. The circuit is completed by a second similar shoe engaging the other conductor bar. Apart from supplying current the conductor bars also form a headed portion which overlaps the drive and idler rolls, and guide rolls to prevent them jumping the rail.

The decomposition is carried out by heating the bleomycin A 2  at about 80‹ to 120‹ C. for 3 to 24 hours either on its own preferably under reduced pressure or in an inert atmosphere (e.g. nitrogen), or in a non-solvent liquid medium, e.g. toluene, xylene, benzene, tetralin, cyclohexane, ethyl acetate or butyl acetate. The product, which contains demethylbleomycin A 2  together with unchanged bleomycin A 2  is dissolved in 0À05 molar aqueous ammonium chloride, adsorbed on cross-linked dextran gel and eluted with 0À1M ammonium chloride, when the demethylbleomycin elutes first followed by the starting material. Each fraction is adsorbed on charcoal, washed and eluted with aqueous HCl/acetone, then treated with anion-exchange resin at pH 6À0 followed by evaporation of the solvents, to give the required demethylbleomycin A 2  and bleomycin A 2  (as the copper-containing hydrochlorides). The latter compound may then be re-cycled to give a further yield of the demethyl compound. The demethyl bleomycin A 2  copper-containing hydrochloride may be treated with H 2 S in methanol to give the copper-free hydrochloride and/or treated with anion-exchange resin to replace HCl by another anion, e.g. Br-, SO 4 -, H 2 NSO 3 -, CH 3 COO- and cyclohexylsulphamate.

Abstract: 1316116 Spinning yarns; textile drafting rollers COURTAULDS Ltd 1 Oct 1970 [2 Oct 1969] 48428/69 Headings DID and D1F A yarn of varying colour characteristic is produced by drafting and twisting together yarn components, e.g. slivers, rovings or tops, of which at least one is of different colour character, i.e. of different colour or different dyeing affinity, from the remainder. This one component is fed to the drafting stage at different rates, the rate of feed of the remainder being changed in timed relationship with change in the rate of feed of the one component so that the yarn when formed will be uniform in cross-section. Each component is drafted between back rollers exclusive to itself and front rollers common to all the components and then passes to twisting spindles. The paths between each of the back rollers and the front roller and the speeds and forms of rollers are such as to subject the components to identical drafting conditions. In the operation of the apparatus shown, pairs of components 50, 51 (of different colour character) and 52, 53 (also of different colour character) pass through channel guides 54, 55, and 56, 57 and through conical guides 58, 59, and 60, 61, to the nips of back rollers 6 and 10, 7 and 11, 8 and 12, 9 and 13, thence through condensers 62, 63, to front rollers 23, 24, and 25, 26, and subsequently to spindles whereby they are formed into yarns. Clutches 35 and 37 are energised alternately under the control of time-switch operated switches, Fig. 3 (not shown) to transmit a drive from main shaft 38 alternately to shaft 5 carrying rollers 6 and 9 and to shaft 20 thence to sleeve 16 carrying rollers 7 and 8. The rates at which the controlling switches open and close are adjusted so that the phasing-out of the feed of one component of each pair and the phasing-in of the feed of the other component at each changeover of the drives yield a final yarn of uniform cross-section.
