Title: Colouring matters of the phthalocyanine series
IPC: C09B47/08
Filed: 1938-12-08
Abstract: 522,293. Dyes. BRADBROOK, E. F., COFFEY, S., HADDOCK, N. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Dec. 8, 1938, No. 35892. [Classes 2 (iii) and 15 (ii)] New pyridinium salts are made by reacting pyridylphthalocyanines with dialkyl sulphates or sulphites, alkyl benzene sulphonates, alkyl p-toluene sulphonates, and alkyl chlorides or bromides. The parent pyridylphthaloxyamines are made by heating pyridylphthalic dinitriles with metal-yielding substances or with hydroxy compounds or acid amides, by heating pyridylphthalic acids, anhydrides or imides with urea and metal-yielding substances, or by heating o-dihalogenophenylpyridines or o-halogenocyanophenylpyridines with cuprous cyanide. These pyridylphthalocyanines dissolve in aqueous solutions of sulphamic acid, and dry compositions suitable for preparing dyebaths may be made by mixing the pyridylphthalocyanines with sulphamic acid. The pyridinium salt may be formed by heating the pyridylphthalocyanine with the alkyl salt ; alternatively, pyridinium salt formation and pyridylphthalocyanine formation may be effected in one operation by heating together an alkyl salt, a pyridylphthalodinitrile and a metal-yielding substance. The quaternary salts from tetra- 4-pyridylphthalocyanines show direct affinity for cellulosic fibres in general, including cotton, paper and viscose, and may be used for direct dyeing in blue-green to green shades ; those from tetra-3-pyridylphthalocyanines have affinity for viscose, but are unsuitable as direct dyestuffs for cotton. In examples, (1) copper tetra-4-pyridylphthalocyanine (made from 4- pyridylphthalodinitrile, see example 1 of Specification 521,749) is converted (a) into the tetramethylpyridinium methosulphate by treating with dimethylsulphate or with methyl alcohol and dry hydrochloric acid, and (b) into the tetra methylpyridinium-p-toluenesulphonate with methyl-p-toluene sulphate ; the same product is obtained from 4-pyridylphthalodinitrile, methyl-p-toluene sulphonate and cuprous chloride, (2) metal-free tetra-4-pyridylphthalocyanine (made by heating 4-pyridylphthalodinitrile with triethanolamine, or by removing the lead from lead tetra-4-pyridylphthalocyanine with acid) is treated with dimethyl sulphate, (3) aluminium tetra-4- pyridylphthalocyanine (made by heating 4-pyridylphthalodinitrile with anhydrous aluminium chloride) is treated with dimethyl sulphate, (4) lead or zinc pyridylphthalocyanines (made by heating 4-pyridylphthalodinitrile with litharge or zinc) are treated with methyl ptoluene sulphonate, and (5) copper tetra-3- pyridylphthalocyanine (made by heating 3- pyridylphthalimide (Specification 521,749, example 3) with urea and cuprous chloride) is treated with dimethyl sulphate or methyl p-toluene sulphonate.

As shown, in a combined torque converter, or fluid coupling, and variable-speed epicyclic gear, a first planet train comprises an engineconnected ring 3, a carrier 4 connected to the fluid-coupling impeller 6, and a sun 7 which may be clutched to the carrier at 9 or braked at 8 respectively for direct or reduced drive of the impeller, and a second planet train comprises an output carrier 13, a sun 12 connected to the fluid-coupling runner 10, and a ring 14 which for first and second gears is braked, the whole of the drive passing through the fluid coupling, and for third and fourth gears is clutched at 16 to the impeller 6, the drive being split into two paths between the first and second trains, one direct mechanical and one through the fluid coupling. A reversing train compounding with the second train is shown, but not described. For forward drive in first and second gears the ring 14 may be braked directly (Fig. 1, not shown) or, as shown, by a one-way detent 22 braked at 23 which latter need only be released for reverse. As shown, a direct brake 15 for the ring 14 provides for engine braking on overrun in second gear. The overdrive/direct train 19, 18, 17 is arranged in the mechanical path as an alternative to the clutch 16, the carrier 18 and the ring 17 being connected to the impeller 6 and the ring 14 respectively, and the sun 19 being braked at 20 for overdrive. Whilst the overdrive may be used on third and fourth gears it is used only on fourth gear to provide fifth gear. To prevent undesirable high-speed idle overdrive of the sun 19, an hydraulically engaged, spring disengaged, multiplate friction clutch may be provided between the carrier 18 and the impeller 6 and disengaged in first and second gear. The clutches may be, as shown, of the multiplate friction type, hydraulically actuated, or fluid couplings filled and emptied to be engaged and disengaged. The torque converter or fluid coupling 6, 10 may be replaced by an hydrodynamic device acting as a coupling in one range and as a torque converter in another range, or emptied and filled in different drive conditions. Control of the overdrive may be manual and/or automatic, e.g. manual-hydraulic overridden, to return to direct drive, by road speed responsive governor pressure.

Abstract: 412,286. Pencil holders. LIVSEY, W., 13, Hope Street, Liverpool. Dec. 30, 1932, No. 36832. [Class 146 (iii).] In a propelling pencil means comprising a common spring interposed between the leadholding socket and the single lateral pin of the propeller rod are provided for reengaging the action after overwinding at either end of the travel, and for returning the parts to normal position after the lead - expelling action. The propeller rod 15, Fig. 1, is provided with the usual lateral pin 16 engaging with the slots 14, 13 of a rigid brass spiral 1 and a tube 2. The tube 2 is fast to a point member 4 and the spiral 1 is pinned to a connecting member 7 which projects loosely into the point 4. On the rear end of the tube 2 is fixed a cap 11, provided with a slot 12 registering with the slot 13. The cap 11 retains the spiral on the tube and thereby holds the point 4 and the barrel together. A split lead-holding tube 18 slides on the rod 15 and has secured to it a tube 22, slotted at 24, Fig. 4, to accommodate the pin 16. A small collar 20, slotted at 21, also slides on the propeller rod inside the tube 22, and between the collar 20 and tube 18 is provided a spring 19. When the propeller assembly is fully retracted, the collar 20 first meets the cap 11, during the subsequent movement of the pin 16 to escape from slot 14 to slot 12, the pin 16 presses on a portion 23 of the tube 22 and moves the tube 22 and tube 18 to compress the spring 19. Thus, overwinding can take place but, as soon as the direction of rotation is reversed, the spring pressure on the projection 16 returns it to the slot 14. When the assembly is fully advanced, the lead-holding tube 18 first strikes the shoulder 26 of the point and then, as the pin is further advanced into the free space 8, it compresses the spring 19 by pressing on a shoulder 25 of the collar 20. Thus overwinding can take place and the projection is immediately returned to the spiral slot when the direction of rotation is reversed. Alternatively, the tube 2 may be constricted at one part to arrest the motion of the spring, or the overwinding action may take place at one end of the motion only.
