Abstract: 646,706. Control of two D.C. motors. JENKINS, R. G. C. (Abbey, N. D.). May 15, 1947, No. 13158. [Class 38(iii)] [Also in Groups V, VIII and XXII] In a tube forming mechanism including a cut-off device (see Group XXII), the carriage 24, carrying the cutting-off device 25 is driven to and fro on rails 22 in synchronized relation with the tube 15, by an endless chain 26 from a reversible D.C. motor 34. The motor armature is fed from a generator 48 driven from the main drive shaft 18 so that variation of the speed of the tube mill drive results in a corresponding variation of the speed of the motor 34 over the greater part of the travel of the carriage 24. The carriage is decelerated towards the end of its travel in either direction in order that reversal may be made gently, by the operation of limit switches 36 or 39 by cam arms 43, 42 respectively, whereby a rheostat 50 is inserted in the generator field circuit, the back e.m.f. of the motor then overcoming the output voltage of the generator, and power is fed back to the generator, acting as braking means on the motor 34. Reversal at the end of the travel in either direction is effected by the operation of limit switches 35 or 40 which reverse the supply to the generator field.

Patent GB-887590-A (GB)
Title: Dimerization of monoolefins
IPC: C07C11/02
Filed: 1959-04-20
Abstract: Olefines having 6-12 carbon atoms are dimerised in the presence of a boron trifluoride hydrate with a ratio of 0.5-100 mols of olefin per mol of catalyst at 0 DEG C.-60 DEG C. with intimate mixing for 0.1-6 hours and recovering the dimer.  Single olefines may be dimerised or mixtures, e.g. low polymers obtained by polymerisation of propylene, olefines obtained by steam cracking hydrocarbons or cracking waxes. Pressures of 0-150 p.s.i.g. are preferred.  After settling, the catalyst phase is separated and the hydrocarbon phase washed with water which may contain caustic soda; boron trifluoride may be recovered from the washings.  The product is then distilled to remove unreacted olefines and higher boiling polymers.  The products are useful in the production of plasticisers, detergents, oil-soluble sulphates and as feedstocks for the oxo reaction.
Patent GB-134867-A (GB)
IPC: C10B39/04
Abstract: 134,867. Wellington, S. N. Aug. 19, 1918. Cooling discharged materials.-In a cokequenching apparatus of the kind consisting of a chamber which can be moved into alinement with the oven, and is large enough to receive the whole charge therefrom on a floor formed by an endless conveyer, the chamber is water-jacketed, and the spraying-pipe connexions are so arranged that the water is forced on to the coke to be cooled by the steam pressure generated within the jacket. As shown, the chamber a is mounted on a truck c, and is provided with vertically-moving end doors and a movable discharge shoot n controlled by a pivoted rack n<1> and a hand-wheel. The conveyer g passes over end sprockets h, one of which may be adjustable, and the lower lap is cooled by water in a trough having an overflow to maintain a constant water-level. Dust can be removed from the trough by opening an end door and operating the conveyer in the reverse direction to that of normal working. The walls of the chamber form an inverted-U shaped steam-generator which is provided with a steam drum k, a safetyvalve, and the usual gauges. Within the chamber, water-spray pipes are fitted, and their controlling-valves may be connected for simultaneous operation by an outside cable s. These spray pipes take their water-supply from pipes which extend nearly to the bottom of each limb of the generator, so that when the valves are opened the water is forced on to the coke by steam pressure. Mounted on the apparatus is a steam-engine p which is arranged to drive, through gearing and a clutch, either the wheels of the truck or the conveyer g, and it can also run free of both, so that it can be used for hauling coke wagons &c. The engine takes steam from the drum k or from a reservoir m for excess steam and water.
Patent GB-134928-A (GB)
IPC: F02M69/00
Abstract: 134,928. Matricardi, G. Nov. 13, 1918. Spray carburettors.-Fuel is sprayed into a small separate chamber, where it is mixed with a small portion of the total air supply, the resulting mixture passing through a heated chamber to the induction tube, where it is mixed with the bulk of the air supply which is admitted past a suctionactuated valve which actuates the fuel valve, the fuel supply being controlled by a pressure regulator which may be independently adjusted while the engine is running. Fuel from a tank 18 passes by way of a valve 23, pipe 8, and needle valve 12 to a chamber 5, to which air is admitted through ports 6. The mixture passes through a pipe 13 heated by an exhaust conduit 14 to the induction pipe 2 on the engine side of the throttle valve 3. The bulk of the air supply is admitted past a suction-actuated spring-loaded valve 9 working in a casing 4 and carrying the needle valve 12.

A three-way cock 27 may place the valve 23 in communication with a lightfuel tank 29. The portion of the pipe 13 in the conduit 14 may be of U shape to increase the heating-surface.
Patent GB-583958-A (GB)
Title: Improvements in and relating to package binding
IPC: B65B13/12
Filed: 1944-07-14
Abstract: 583,958. Package binding mechanism. CHEESMAN, J. J. July 14. 1944, No. 13544. Addition to 553,788. [Class 94 (i)] [Also in Group XXXVII] The mechanism described in the parent Specification for binding articles with flexible strip is modified by the provision of coil size limiting means whereby upon the accummulation of a predetermined amount of strip, or the withdrawal of strip beyond a predetermined limit, electrical means operate a warning signal, or act to stop the machine temporarily or permanently. When stopped temporarily a hand-switch can restart the machine, but permanent stopping means involves resetting of the machine. The invention is described as applied to the machine described in Specification 566,309 which is also a modification of the invention of the parent Specification, and the packing wire S is passed over rollers 50x and restrained by a band 57b as in the prior Specification, and a switch P is provided which is controlled by a curved feeler 65 which extends across two rollers 50x so as to eliminate vibrations which would occur if a smaller feeler were employed. The feeler 65 is attached to-a spring-controlled plunger 63, Fig. 5, which moves radially of the ring which supports the wire S and binds it around the stationary package. Pivoted to the plunger 63 are two snap contact members 63c adapted to engage spring contacts 61a or 62a which are connected in parallel by strips 66 and are arranged in a circuit including an automobile push-button control switch, the electromagnet of which is temporarily de-energized when the members 63c which normally engage the contacts 61a are moved to engage the contacts 62a as shown in Fig. 5 on passage of their pivot 63e past dead centre position; a spring 63d assisting the snap action. This occurs when the plunger is forced outwards by the wire. If the machine continues to run further outward movement of the plunger 63 breaks the circuit completely and the machine has to be re-set before packaging can continue. When the feeler 65 is set so as to act only upon accumulation of excessive wire the springs of contacts 62a are made stronger than those of 61a and upon reversal of the members 63c the snap action occurs so quickly that the electromagnetic switch fails to be de-energized sufficiently to break the circuit. The switch can be arranged to operate warning movement of the plunger 63. The plunger 63 can operate warning signals instead of or in addition to the operation of the electromagnetic switch. A single pivoted snap action may replace the double snap action device shown.

Title: Improvements in the manufacture and production of vat dyestuffs
IPC: C09B3/32
Filed: 1933-05-10
Abstract: Vat dyes are prepared by reacting dibenzanthrone, isodibenzanthrone or their halogen substitution products in a halogen-sulphonic acid with chlorine or bromine or agents supplying these halogens, in the presence of at least 2 per cent of sulphur by weight of the mixture of the said compound and halogen-sulphonic acid.  Preferably, between 8--12 per cent of sulphur by weight of the mixture of dye and acid is employed or a corresponding amount of a substance supplying sulphur, such as sulphur monochloride, is employed.  Temperatures up to about 80 DEG  C. may be used and halogenation catalysts may be present. The products contain halogen and sulphur and are insensitive to temperature in dyeing, yielding green-blue to violet-blue shades fast to drops of water.  In examples, (1) dibenzanthrone is brominated in chlorsulphonic acid in presence of about 9 per cent sulphur to give a product containing bromine, chlorine and sulphur; (2) dibenzanthrone is chlorinated in chlorsulphonic acid in presence of about 9 per cent of sulphur at 50 DEG  C.; by adding to the reaction mixture before leading in the chlorine a small amount of bromine a dyestuff containing chlorine, bromine and sulphur is obtained; (3) dibenzanthrone is treated with potassium bromide in chlorsulphonic acid in presence of about 8 per cent sulphur; (4) monobromdibenzanthrone (prepared by bromination in chlorsulphonic acid in presence of a small amount of sulphur) is brominated in chlorsulphonic acid in presence of about 11 per cent sulphur. Specification 341,229 is referred to.

Title: Improvements in or relating to submarine mines
IPC: F42B22/00
Filed: 1927-05-24
Abstract: 296,040. Vickers, Ltd., and Pratt, H. B. May 24, 1927. Mines, marine.-Relates to submarine mines of the kind having a stream line casing adapted to be attached at the end of its axis of symmetry to a mooring cable, and consists mainly in so disposing the weights of the mine that the downward moment of the weights and the upward moment of the buoyancy about the point of attachment are balanced or nearly balanced, whereby the mine is maintained stable with its axis along the direction of the current. As shown in Fig. 1, the mine 1 is attached at its nose 7 to a mooring cable 6. The centre of buoyancy is at 9 and the centre of gravity at 8. A weight 4 is adjustably attached to one of the tail fins 3 to regulate the position of the centre of gravity. The tension of the mooring cable is adapted to arm the mine by an arrangement similar to that described in Specification 262,917. The mooring cable 6 is attached at 7 to the outer end of a lever 20, Fig. 2, pivoted in a watertight socket 22 and connected at its inner end by a link 24 and an arm 25 to a switch 17. A spring 26 bears on the lever 20 and holds the switch open until the pull of the cable overcomes the spring and closes the switch, thereby arming the circuit of horn batteries 15. This arming operation is delayed until a soluble 'plug 27 has dissolved away and released a bolt 28 locking the lever 20. The inner end of the lever 20 is also connected by a Bowden wire 35 to a slotted link 36, Fig. 3, connected with a trigger 33. When the lever 20 closes the switch, it also pulls this trigger and releases a piston rod 34, which is moved by a spring 32, bringing a primer 31 against a detonator 18.
