Title: Improvements relating to chlorine-containing catalysts
IPC: C07C5/27
Filed: 1962-06-26
Abstract: C4 and higher paraffin hydrocarbons boiling in the gasoline range are isomerized in the presence of hydrogen below 400 DEG  F. with a catalyst containing A12O3 and from 1-15% of chlorine, at least part of the chlorine being attached at electron deficient sites which are characterized by the fact that on reaction of the catalyst with dry benzene in toluene, electron spin resonance spectra of a radical cation of benzene or toluene are obtained at N.T.P.  Isomerization is preferably applied to pentanes and/or hexanes. Typical isomerization conditions are:-Temperature from 50 DEG  up to 400 DEG  F. preferably 150-350 DEG  F. Pressure 0-20000 p.s.i.g., preferably 225-1000. G.H.S.V.=0.05 to 10 v./v./hr. Hydrogen/hydrocarbon mole ratio 0.01 to 20:1.  If desired HCl or CCl4 may be added to the reaction zone.  The main isomerization product is 2:2-dimethylbutane.ALSO:A catalyst suitable for use in hydrocarbon conversion processes comprises alumina and from 1-15% of chlorine by weight, at least a part of the chlorine being combined with the alumina at electron deficient sites which are characterized by the fact that, on reaction of the catalyst with dry benzene or toluene, electron spin resonance spectra of a radial cation from benzene or toluene are obtained at atmospheric temperature and pressure.  The catalyst may be prepared by contacting alumina with SOCl2 under non-reducing conditions and at a temperature of from 300-1100 DEG  F. such that chlorine is taken up by the alumina without production of AlCl3.  The carrier may be rho, chi, eta or gamma-Al2O3 although kappa, theta and delta aluminas are also mentioned.  The surface area of the catalyst may be more than 250-300 sq. m./gm.ALSO:A catalyst suitable for use in hydrocarbon conversion processes comprises alumina and from 1-15% of chlorine by weight, at least a part of the chlorine being combined with the alumina at electron deficient sites which are characterized by the fact that, on reaction of the catalyst with dry benzene or toluene, electron spin resonance spectra of a radial cation from benzene or toluene are obtained at atmospheric temperature and pressure.

Title: Improvements in or relating to straight-bar knitting machines
IPC: D04B11/00
Filed: 1936-09-03
Abstract: 471,584. Knitting-machines. BLACKBURN & SONS, Ltd., G., and START, H. W. Sept. 3,1936, No. 24521/35. [Class 74 (ii)] An electromechanical unit for adjusting anti-friction rollers or other members in a straight-bar machine comprises a slidable member that is also angularly movable, under control of an electromagnet, into and out of engagement with a mechanical device and which, when moved by the latter device, operates the part to be adjusted through a supplementary sliding member that is locked on being moved from its normal position. As shown in Figs. 1 and 3, on energization of an electromagnet L, a lever J, loose on a shaft K and connected to the armature L, is rocked so that its roller J<1> is acted on by a face cam H<1> on a shaft G which revolves at the same speed as the main cam-shaft D. The lever J is thus moved to the right (as viewed in Fig. 3), pushing before it a sliding member M, against the action of a spring M<4>. A slidable rod M<1> is thus resiliently urged to the right, through the medium of a spring M<2>, and, through a second rod Q and a bracket Q<1>, shifts a roller Q<4> from one to the other of two cams Q<6> as soon as the positions of these cams permit such movement. When the member M is moved to the right, it rocks a locking member P about a fixed pivot O and a stud P<1> thereon is thus made to follow an upper cam track N<1>, the stud P<1> being finally pulled down to the central point of a cam track N<3>, under the combined action of springs M<4>, P<4>, so locking the member M. To release the member M, the electromagnet is again excited to move the roller J<1> into the path of the cam H<1>, and the member M is moved far enough to the right to cause the stud P<1> to move into a lower cam race N<2>, back along which it is free to travel when lever J is allowed to return by the cam H<1>. This allows spring M<4> to return the member M and hence the rod M<1>, by means of a collar M<5>, against which the member M acts. At the end of its travel along the cam race N<2>, the stud P<1> trips a spring-controlled switch N<4> which normally closes the entrance to the lower race N<2>, and so again enters the upper race N<1>. The current to the electromagnet is controlled by one of a series of switches A, actuated by lifts B<1> on a drum B which is racked round by a pawl C and ratchet wheel B<3>. The pawl is operated through links, by a cam C<5> on the camshaft D, but is rendered effective or ineffective by a controlling disc C<2>, which is, in turn, controlled by the main pattern chain E. A complete electromechanical unit is provided in connection with each part of the machine which has to be adjusted.

Title: Heating tube systems incorporating means for providing uniform distribution of the heated medium
IPC: F22D1/02
Filed: 1962-06-27
Abstract: <PICT:0938723/III/1> Uniform distribution of a medium consisting of a mixture of liquid and vapour flowing from a single supply tube 1 via a header 7 to parallel tubes 2, 21 disposed in a furnace so as to be heated thereby is achieved by inserting within the discharge end of the tube 1 an axial core or mandrel 8.  The medium may be a water/steam mixture in the tube system of a forced flow steam generator or a mixture of petroleum fractions or of other liquids one of which is at least partially vaporized, in a distillation unit. The core 8 extends into the supply tube for a distance between one tenth and one third of the length of the tube and may be of conical or other streamlined form.  The annular passage 9 left between the core and tube results in a flow of increased velocity and consequently of very intimate dispersion of the vapour in the liquid with resultant uniform distribution to the parallel tubes.

Abstract: 481,569. Hydraulic shock absorbers. PRATT, J. H., MANLEY, G. E., and GIRLING, A. H. G. Sept. 14, 1936, No. 24953. [Class 108 (iii)] In a hydraulic shock-absorber any increase in the volume of liquid due to temperature changes is compensated for by a variation in volume of a flexible or resilient member which is disposed inside the shock-absorber casing and is subject both to atmospheric pressure and to the pressure of the liquid. In the shock-absorber shown, pistons 3a, 3b connected together and held in engagement with the ball-end 10 of the operating crank 11 by a bent wire spring 9, are adapted during operation to force liquid from either cylinder 1a, 1b through a byepassage 34 or 35 in the shock-absorber casing and into the interior of a tube 24a or 24b through a port 26 on the wall thereof, thus moving a ball-valve 21 against the action of a spring 28 until the corresponding port 26 in the other tube 24b or' 24a is uncovered by the ball when the liquid flows out through the port and byepassage 35 or 34 to the other cylinder. On the return movement of either piston towards the centre of the. shock-absorber liquid passes from the central reservoir space 2 through a non-return valve 8 on the piston to the other side of the piston. Any expansion of the liquid due to increase in temperature causes compression of a rubber bag 15 the open end of which is fixed in the hollow operating shaft 12 by means of a metal thimble 16 pressed into the outer end of the shaft and apertured to permit communication between the bag and the atmosphere.

Filed: 1928-08-31
Abstract: 303,411. Akt.-Ges. Brown, Boveri, et Cie. Jan. 2, 1928, [Convention date]. Heating parts. - Means are provided for preheating a turbine and for keeping it hot in order that it may be put into operation quickly, when required, without it being subjected to heavy heat stresses. This is achieved by passing through it a heat carrier, such as superheated steam or air, which has been heated so that it will preheat the turbine to a temperature equal to that prevailing when the turbine is in operation. Fig. 2 shows an arrangement in which air, heated in a steam heat-exchanger 10, is passed through a pipe 11 to the first stage 5 of the turbine from which it is drawn off at a point 7, which may also be a steam tapping point, and returned by a fan 8 to the heat-exchanger. The air also serves to heat the valve gear 15, and may have access to the interior of the rotor. The heat-exchanger 10 may be heated by an oil furnace or flue gases. During preheating the turbine shaft may be turned slowly by a barring device. When the turbine is to be put into operation, the heating system is cut off by closing valves 16, 17. In a modification, flue gases from the boiler are used as the heat-carrier. Fig. 4 shows an application to a multistage turbine 25, 26, 29 in which the heated air is driven by a fan 27 throughthe first two stages in series, the final stage being left open without flow, or being kept under vacuum. The air is heated by electric heating elements 35, 36, 37, connected in series or in parallel according to the heat required. The flow of heating air through the stages may be varied and regulated. Fig. 6 shows a modification in which the air, heated by an electric device 54, is caused to circulate in the space 57 outside the turbine casing 59 after it has passed through the turbine. The electric heater may be controlled by a thermostat 60 acting through a relay device 63, 64, and a controller 65. Relay controlling devices may be employed where steam or flue gases are used as sources of heat.

Filed: 1962-06-23
Abstract: A lubricating composition comprises ground molybdenum disulphide and a dispersing carrier, stabilizer or the like including oil, water, alcohol or mixtures thereof or resin solutions containing thermosettable or thermoplastic carriers.  In an example, a water or oil dispersion contains 10-40% of ground molybdenum disulphide.ALSO:Molybdenum disulphide is ground in the presence of salicylic acid or phthalic anhydride as a grinding aid.  The grinding aid is 0,1-3 times, preferably twice, the weight of the disulphide. The disulphide is ground, preferably in a ball mill, until it is in a particulate form having a mass mean diameter between 0,45 and 2 microns and containing a maximum of 0,1% by weight of particles larger than 32 microns.  After grinding, the disulphide is separated from the grinding aid.  For example, the ground material is slurried with an alcohol, preferably isopropyl alcohol, and the slurry filtered to separate the disulphide from the alcohol solution containing the dissolved grinding aid. Alternatively, the grinding aid is removed from the ground material by sublimation.  Examples are described.
