Title: Improvements in fluid couplings
Inventor: BECKER JOHN EDWARD
IPC: F16D33/14
Filed: 1959-03-13
Abstract: 882,807. Hydraulic couplings. ROBSON, C. March 4, 1960 [March 13, 1959], No. 8863/59. Class 69 (2). A method of controlling a fluid coupling having an impeller 2 and runner 4 between a driving motor and a load comprises automatically varying the volume of fluid in the coupling in relation to the speed of rotation of the reservoir of the coupling whereby the power transmitting capacity of the coupling is analogous to the power producing capacity of the motor. The reservoir is divided into chambers 12, 13, 23 and 28, the chamber 23 communicating with the working circuit of the coupling by means of a peripheral gap 24, and with the chambers 12, 13 by a scoop tube 26 having nozzles 31, 32. Each chamber 12, 13 has a scoop tube 15, 16 which is carried by a yoke 17 mounted in bearings 18 and urged to a neutral position by a torque bar 19, and each scoop tube is connected by a flexible pipe 20 to a passage 30 leading to the chamber 28 from which fluid is passed to the chamber 23 by a scoop tube 25. During rotation the scoop tubes 15, 16 are moved radially by centrifugal force against the force of the torsion bar and the centrifugal force acting on counterweights 22, scoop tube 15 being arranged to move radially inwards, and scoop tube 16 radially outwards, with increases in the speed of rotation of the reservoir. In the lower speed ranges, both scoop tubes 15, 16 are in their radially-outermost position to empty the chambers 12, 13 and the coupling is filled. In the higher speed ranges, the centrifugal force moves the scoop tube 15 radially inward so that fluid accumulates in the chamber 12 and the slip of the coupling increases. When the engine is slowed by a load tending to stall the coupling, the scoop tube 16 moves radially inwards so that fluid accumulates in the chamber 13 to increase the slip of the coupling.

Title: Alkylation of hydrocarbons utilizing evaporative cooling
IPC: C07C2/62
Filed: 1955-03-28
Abstract: <PICT:0803481/IV (b)/1> Isoparaffinic hydrocarbons are alkylated with olefinic hydrocarbons by intimately mixing them in the presence of an acid catalyst in a reaction step maintained under pressure sufficient to maintain the reactants in liquid phase, withdrawing the hydrocarbon and catalyst mixture, separating the acid catalyst from the reactants, chilling the effluent by self evaporative cooling, and passing the chilled reactants without separation in indirect heat exchange with the mixture of hydrocarbons and acid being alkylated so as to lower the temperature of the materials undergoing reaction.  In a preferred embodiment, butylene is added through line 9 and isobutane through line 10 and fed to a heat-exchanger 12 and then to the reactor 1 to which is also fed 98.6 per cent sulphuric acid through line 15.  Alkylation is effected by rapid agitation by the impeller 3 and then the mixture is discharged through pipe 19 to the acid settling tank 16.  The hydrocarbon phase separated in the settler passes through line 21 and pressure is reduced at valve 22 after which the liquid vapour mixture is passed through line 23 to the distributing-head 5 of the reactor and through the tube bundle 4 where, as a result of the reduction in pressure, it acts as a coolant.  The chilled and partially vaporized effluent passes from the opposite side of the circulating head, through line 24 to suction trap 25 where, on separation, the liquid passes by pump 29 through pipe 30 to heat-exchanger 12, and then to neutralization and fractionation steps shown at 32.  The vapours separated out pass through line 33 to compressor 34 from which they are discharged through line 35 to condenser 36.  U.S.A. Specification 2,649,486 and 2,664,452 are referred to.

Title: Improvements in the manufacture and production of acrylic esters from ª‰-chloropropionic acid esters
IPC: C07C69/54
Filed: 1930-03-24
Abstract: Ten parts of highly active granulated charcoal are mixed with 5 parts of an aqueous sodium silicate having a specific gravity of 1,38.  The mixture is dried by heating at 100-150 DEG  C., and the dry granules are impregnated with a mixture of 3 parts of pure phosphoric acid, 1 part of barium oxide, and 1 part of phosphorus pentoxide, and heated at 200 DEG  C.  The grains are then allowed to cool while excluding the access of moisture.  The catalyst is used p  in the treatment of vapours of b -chloropropionic esters, acrylic esters being produced.ALSO:Hydrogen chloride is split off from b -chloropropionic esters by means of acid-reacting, difficultly-volatile substances containing an inorganic radicle, e.g. concentrated sulphuric and phosphoric acids, zinc chloride, toluene sulphonic acid or mixtures thereof.  the amount of catalyst required is usually at least 5 per cent by weight of the ester, about 10 per cent being preferred.  When the process is carried out continuously by distilling off the acrylic ester formed, the catalyst serves for a p  considerable time.  In the liquid phase the temperature of working depends on the boiling-point of the ester employed, but it is preferred to have the temperature not substantially above 200 DEG  C., the process usually being carried out in vacuo.  If the reaction is carried out in the vapour phase, temperatures between 150-250 DEG  C. are usually preferred, and the catalyst may be supported on a carrier, e.g. active charcoal may be impregnated with a mixture of phosphorus pentoxide and phosphoric acid, or with sodium silicate followed by a mixture of phosphoric acid, barium oxide and phosphorus pentoxide.  Examples are given.

An inductor-type cycle hub generator has an annular rotor 10 having at its inner periphery two staggered sets of teeth 12 surrounding a stator comprising two coils 23, 24 embracing an axially polarized permanent magnet 15 having at its ends toothed pole-pieces 18. Each pole-piece 18 is transversely fitted to the magnet 15 and has two staggered sets of diametrically opposed teeth 21, 22. The rotor and stator pole-piece teeth have the same width and pitch. When the pole-pieces are mounted on the magnet 15, the teeth 22 of both pole-pieces are in alignment with each other, and the other teeth 21 are also aligned with each. As the rotor revolves with the hub, the flux from the magnet 15 alternates in its flow via the pole-pieces 18 according to the position of the pole-piece teeth 21 or 22 relative to the rotor teeth 12. Thus, when pole-piece teeth 22 are in alignment with one set of the rotor teeth 12, the flux flows to embrace the coil 23 or 24. As the rotor revolves one tooth pitch, the flux flows to embrace the other winding.
