Fluorine -containing chlorocarbon compounds are prepared by electrolyzing a chlorohydrocarcarbon in liquid anhydrous hydrogen fluoride while subjecting the reaction mixture to agitation as by means of a stirrer which may form the anode. A readily ionizable compound, e.g. anhydrous lithium fluoride, may be included in the cell to facilitate the reaction. The process may be carried out in a modification of the cell disclosed in Specification 668,609, in which the nickel anode is rotated by a motor, the anode-bearing shaft passing through a stuffing-box in the cell lid packed with shredded polytetrafluoroethylene. A drain may be provided in the cell and the cell may be surrounded by a cooling bath. Alternatively, as shown, the anode may comprise fixed parallel nickel plates 22 on opposite sides of a hollow shaft 23 carrying paddles 24 whereby on rotating the shaft the electrolyte passes up the inside of the shaft and is dispersed by the paddles.

Title: Improvements in clutches
IPC: F16D27/105
Filed: 1948-09-03
Abstract: 647,448. Belt pulleys ; friction clutches. COMMUNICATION ENGINEERING PTY., Ltd. Sept. 3, 1948, No. 23267. Convention date, Oct. 8, 1947. [Classes 80(i) and 80(ii)] The drive from a shaft 11 to a belt pulley 34 is transmitted through a coil clutch engaged by an electromagnetic friction clutch and which comprises two symmetrically interwound coil springs 14, 15, each secured at one end to a boss 12 on the shaft 11 and supporting at the other end the armature 18 of an electromagnet 21 fast with the drum 34 and with a sleeve 20 round which the springs 14, 15 wrap when the electromagnet is energized to retard the armature 18. The springs 14, 15 are screwed on to a tapered thread on the boss 12 and secured by screws 16, 17. The shaft 11 can move axially relative to the sleeve 20 sufficiently to allow the extension of the springs on contracting, the movement being limited by a collar 33. The armature 18 may have a friction facing 19 of brass or other nonmagnetic material, and the electrical circuit to the electromagnet 22 is made through a slip ring 29 on a stationary insulating plate 26, two contactors 30 in parallel, the electromagnet coil 23, the magnet body 21, the sleeve 20 and the shaft 11. The electromagnet 21 is screwthreaded on the sleeve 20, being positioned thereon by a split nut 24 clamped by a screw 25. Adjustment of the electromagnetic air gap is effected by clipping a special tool 37, Fig. 4, over the collar 33 so that a square shank 38 engages notches in the collar 33 and sleeve 20 to prevent their relative rotation. The nut 24 is then unclamped and slacked off by a pin inserted in holes (not shown), in the nut periphery, the magnet 21 adjusted by a pronged tool engaging similar holes in the end face thereof, and the nut 24 again positioned and clamped. To allow air gap inspection without dismantling, holes (not shown), are provided in the surface of the pulley 34. These holes may be opposite the air gap or, to prevent the entry of dust therethrough, may be opposite the magnet 21 and brought over the air gaps by unscrewing the screws 40 holding the pulley 34 in place and moving the latter axially relative to the magnet 21. The pulley 34 may be covered by an adhesion-promoting layer of rubber or other material also perforated for the screws 40 and for air gap inspection.

Abstract: 1,240,909. Pulse width discriminators. FERNSEH G.m.b.H. 7 May, 1969 [11 May, 1968], No. 23380/69. Heading H3P. In a pulse width discriminator the input pulse (at 1) allows a capacitor 11 to charge to produce an output having an amplitude proportional to the pulse width. This output is applied to a threshold device 13 to provide an output when the voltage exceeds a value corresponding to a minimum pulse duration. A second capacitor 16 is discharged by 15 during the presence of this output and charges when the output ceases, the capacitor voltage being fed to a further threshold device 18 followed by an inverter 19. The time constants and the threshold levels are so chosen that the period during which the second capacitor voltage remains below the threshold after the cessation of the output of the first, is equal to the delay before the first threshold is exceeded so that output and input pulses are of equal length. As shown, the output of the threshold circuits 12 and 17 are shaped by Schmitt triggers 13 and 18. Circuit 14 is a further inverter.

Title: Olefin separation and recovery
IPC: C10G25/03
Filed: 1957-07-24
Abstract: Mixtures of hydrocarbons containing n-paraffins and normally liquid n-olefines are resolved by passing through a molecular sieve at 175-450 DEG F., withdrawing unadsorbed hydrocarbons including cis n-olefines, passing a normally gaseous olefine into the adsorption zone whereby n-paraffins are desorbed and finally purging the adsorption zone and recovering the olefines thereby desorbed. Preferably the adsorption is carried out in the vapour phase at 0-400 psig and a space velocity of 0,1-5 vol./vol./hr. and the n-paraffins are desorbed at the same temperature using propylene.  The purging may be performed with steam at 220-350 DEG F. or an inert gas, such as ammonia or by evacuation; if steam desorption is employed the sieve is reactivated by drying.  The feed may be a vaporised naphtha fraction e.g. boiling in the range 85-450 DEG F. or a catalytic reformate.  Cyclic or branched chain hydrocarbons are not adsorbed.

In a delta shaped aircraft, vertical lift is produced by fans, mounted in the fuselage, to rotate about vertical axis, and driven by the discharge jets from the horizontal propulsion gas turbine engines. Two or four fans may be employed and mechanical coupling between them is provided to enable all the fans to continue working in the event of failure of one of the turbines. The discharge jets are directed, by means of ducting, downwards on to turbine blading mounted round the circumference of the fans. Adjustable static blading is positioned above the fans and fixed stator blading below them which the inlet and outlet air flow are each controlled by longitudinal vanes in the upper and lower wing surfaces. To effect pitch control, either the adjustable stator blades are moved to alter the relative upward thrusts of the fans or the fan rotor blades may be similarly adjusted and vanes in the lower fuselage surface may be inclined to deflect the air stream from the vertical to give control in yaw. By closing more vanes on one side of the fore and aft centre line the line of action of the air stream from the fans can be displaced laterally to afford control in roll.

Filed: 1927-09-08
Abstract: 302,203. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. S, 1927. Separating.-Mixtures of gaseous or low boiling hydrocarbons with or without other organic substances of low boiling point are separated into their components by subjecting them after liquefaction to fractional distillation under elevated pressure. The separation is obtained by gradually releasing the pressure while maintaining the temperature or by gradually raising the temperature while maintaining the pressure. Cyclohexane is decomposed by passing its vapours through a quality tube filled with calcium aluminate at about 600‹ C. as described in Specification 297,398, [class 2 (iii), Dyes &c.], and a mixture is obtained containing 28 parts by weight of ethylene, 14 parts propylene, 4 parts butylene, and 40 parts butadiene. The mixture is liquefied by compression and introduced into a still connected with a tall pressure fractionating column. The pressure is reduced to 15 atmospheres and ethylene alone is liberated. Heat is then applied and propylene distils over at 25‹ C. under pressure of 12 atmospheres while butadiene is separated at 45‹ C. under 5 atmospheres pressure, and finally butylene at 52‹ C.
