Title: A process for dyeing high polymers
IPC: C08F2/44
Filed: 1965-05-26
Abstract: Cellulosic materials; natural protein fibres, e.g. wool and silk; and synthetic polymers, e.g. nylon, polyurethanes, polyesters, polyolefins, p.v.c. and polyacrylonitrile are (1) oxidized in an atmosphere containing molecular oxygen and/or ozone to form peroxides therein, or (2) impregnated with a free radical polymerization catalyst and then optionally heat-treated and are then dyed with dyes containing 1 to 10 polymerizable double bonds in the molecule.  The dyestuff which may be an azo, tri-aryl, phthalocyamine, phenazine, oxazine or anthraquinone dye, either forms a graft polymer with the substrate or forms a homopolymer.ALSO:Cellulosic materials; natural protein fibres, e.g. wool and silk; and synthetic polymers, e.g. nylon, polyurethanes, polyesters, polyolefins, P.V.C. and polyacrylonitriles are (1) oxidised in an atmosphere containing molecular oxygen and/or ozone to form a peroxide therein or (2) impregnated with a free radical polymerisation catalyst and then optionally heat-treated in an oxygen atmosphere and are then dyed with dyes containing 1 to 10 polymerisable double bonds in the molecule.  The dyestuff either forms a homopolymer within the substrate or reacts with the substrate via the double bonds to form a graft polymer.  Dyeing may be carried out in water or in an organic solvent or in a mixture thereof optionally under an inert gas, e.g. nitrogen or carbon dioxide which may be passed into the dyebath.  The dyebath may contain (i) compounds which accelerate decomposition of the peroxide in the substrate, e.g. amine, sulphinic acid, formic acid, diazothioethers, mercaptans phenyl hydrozine, sodium thiosulphate or bisulphite ferrous salts and triethanolamine and (ii) a conventional carrier for the dye.  Azo, triaryl, phthalocyanine, phenazine, oxazine and anthraquinone dyes may be used.

Patent GB-479914-A (GB)
Title: Improved means for removing from gases, oxygen or other active gases
IPC: B01D53/46
Filed: 1936-08-14
Abstract: <PICT:0479914/III/1> Small proportions of oxygen or other active gases, e.g. hydrogen sulphide or other sulphur products are removed from gases such as nitrogen by passing the gas mixture through a chamber provided with means, not dependent on the movement of the gas mixture, for causing molten metal to pass therethrough in the form of fine particles so that the active gas combines with the metal to form a compound which is carried out of the chamber by the uncombined metal.  Suitable metals are lead, cadmium or alloys thereof.  In the apparatus shown, a casing 1 is provided with a bearing 10 for a rotating wheel 2 formed with peripheral buckets 3.  Metal melted in reservoir 18 by gas burners &c., (not shown) flows through holes 22 into the bottom of the casing 1, is lifted by the buckets, and is distributed by serrated teeth 15 on the edges of the buckets into a trough 11 from which it flows down a chamber 13 having inclined vanes 14, the surfaces of which are serrated.  The gas to be purified passes up the chamber 13 through inlet 19 and escapes through outlet 17 formed in the wall of the casing 1.  The molten metal, and the oxide or other compound formed in chamber 13, collect in reservoir 18.  The oxide or other compound is skimmed off the top of the molten metal over a weir by a skimmer 24, and may be reconverted into the metal by heating with reducing-agents.
Patent GB-849010-A (GB)
Title: Method for manufacture of aluminium fluoride
IPC: C01F7/50
Filed: 1957-07-16
Abstract: Oxidic aluminium - containing material is reacted at 38-88 DEG C with phosphate-contaminated fluosilicic acid, solids are removed from the reaction mixture, a quantity of a strong mineral acid sufficient to provide a normality of at least 0.5 is added and aluminium fluoride trihydrate low in phosphate content crystallised and removed from the solution.  The alumina-containing material may be solid hydrated alumina or bauxite and may be added as a slurry; the phosphate-contaminated fluosilicic acid may be that obtained as a by-product of the reaction of phosphate rock with sulphuric acid or in the concentration of wet process phosphoric acid by absorbing the evolved gases in water or aqueous hydrofluosilicic acid.  The aluminium to fluoride ion ratio in the reaction mixture is preferably at least 1:3 and up to 20% Al2O3 in excess of that required for this ratio may be added.  If desired, a water-soluble ferric salt such as the sulphate may be added to the fluosilicic acid to precipitate some of the phosphate present, prior to the precipitation of fluoride. Acids mentioned are sulphuric, hydrochloric and nitric; the acid is preferably first used to wash the solids filtered from the reaction mixture.  The crystallisation may be performed by allowing the solution to stand, or it may be maintained at 10-79 DEG C., and may be assisted by seeding.  The recovery of aluminium and fluorine may be improved by reacting the mother liquor from the crystallisation with a further quantity of the aluminabearing reactant and crystallising the resultant aluminium fluoride directly by allowing to stand, with or without seeding.  This second product is not as pure as the first.  The trihydrate may be dehydrated by calcining at 232-316 DEG C.  Reference has been directed by the Comptroller to Specification 643,379.

Title: Control mechanism
Inventor: NATHO PAUL JULIUS
IPC: F16K31/122
Filed: 1966-05-23
Abstract: 1,090,523. Linkwork; valves. ACF INDUS. TRIES Inc. May 23, 1966, No. 22840/66. Headings F2K and F2V. In a mechanism controlling movement of a member 68, e.g. a valve stem, between two positions, a lever 70 pivoted at 71 to the member 68 is pivoted at one end 88 to a toggle linkage 86, 94 which when in a first position, as shown, locates the pivot 88 so that movement of the other end 72 of the lever 70 causes movement of the member 68, and when in a second position (Fig. 3, not shown) permits movement of the pivot 88 so that movement of said other end 72 does not effect movement of the member 68. A slot 74 in the end 72 of the lever 70 is engaged by a crank-pin 82 of a shaft 78 of a motor 76, the energizing circuit of which includes a master switch 112 and parallel switches 122, 132. A link 90 having a fixed pivot 92 controls the locus of the pivot 88. A spring 100 biases the links 94, 86 leftwards. As shown, a solenoid 102 energized from the switch 112 holds an armature 116 on the link 86 to maintain the toggle linkage in said first position against the action of a spring 69 which urges the member 68 upwards. The motor switches 122, 132 are held open by the lever 70 and the link 86 respectively, the member 68 being in a first, lowermost position. Manual opening of the switch 112, or failure of the electric supply S, deenergizes the solenoid 102, allowing the spring 69 to move the member 68 upwardly to its second position and to move the toggle linkage to its second position (Fig. 3, not shown), the switch 132 being closed. Closure of the switch 112 starts the motor 76, pivoting the lever 70 about 71 to return the toggle linkage to its first position, where it is then held by the solenoid 102. The switch 122 having meanwhile been closed, the motor 76 continues to rotate, causing the lever 70 to pivot about 88, moving the member back to its first position. At the end of this movement the switch 122 is opened and the motor stops, the shaft 78 having completed one revolution. The member (68) forms the stem of a control valve (62), (Fig. 1, not shown), controlling the admission of pressure fluid from a pump (P) to the actuator (42) of a gate valve (10) having a parallel expanding double wedge gate structure (24). The valve (10) is opened by hydraulic pressure on a ram (48) and closed by a spring (58). With the switch 112 closed the valve (62) admits fluid to open the valve (10), opening of the switch 112 allowing closure of the valve (10).

Abstract: 1388039 Automatic exchange system TELEFONAKTIEBOLAGET L M ERICSSON 17 May 1972 [18 May 1971] 23273/72 Heading H4K In a telecommunication system two subscribers who are already engaged in an audio connection can both send a special service request to a connection centre which on reception of both requests causes the establishment of a special connection path between the subscribers. Two systems in which some subscribers have video or data equipment are described. In one embodiment (Fig. 1, not shown) the connection centre is a registering and signalling only centre, each substation with wide band equipment being coupled to a common wide band transmission line via a channel selecting circuit (Fig. 2, not shown) arranged to respond to tones from the centre. In a second embodiment (Figs. 3 and 4, not shown) the connection centre is a wide band switching arrangement capable of interconnecting wide band subscriber lines and trunks. During a call in either embodiment either subscriber can initiate a video connection request by depressing either a transmit or a receive button at his substation. Depression of a button loops a wide band line pair to the associated connection centre which identifies the subscriber and test to see if there is a first tone on the line pair. As there is not metering is initiated and the time pair is coupled to a generator for the tone which is transmitted over the line pair to the substation, then over the audio connection to the other subscriber. If that subscriber responds by depressing his receive or transmit button as appropriate looping the line pair to the associated connection centre, the latter makes a second response identifying that subscriber and testing the line for the presence of the tone. As the tone is present the centre responds and scans the appropriate video links for a free channel. When a free channel is found a tone characteristic of the channel is transmitted to aud registered in (in the case of the first embodiment) the two subscriber channel selecting circuits or (in the case of the second embodiment) the connection centre equipment which responded to the first subscriber to initiate a video connection request. The required connection is established and retained until one or other subscriber depresses a release key. The direction of video transmission can be reversed during the call by both subscribers depressing the appropriate buttons.
