Title: Improvements relating to the dehydration of aliphatic alcohols
IPC: C07C29/82
Filed: 1942-02-04
Abstract: 566,025. Dehydrating alcohols. STANDARD OIL DEVELOPMENT CO. Feb. 4, 1942, No. 1461. Convention date, Dec. 27, 1940. [Class 32] Aliphatic alcohols containing from. 2-5 carbon atoms in the molecule and boiling up to 150‹ C. are dehydrated by azeotropic distillation with an entrainer comprising an aliphatic hydrocarbon having from eight to twelve carbon atoms in the molecule, particularly polymers of unsaturated hydrocarbons, e.g. iso-octane, di-isobutylene, iso-octene. A mixture of iso-propyl alcohol and water is fed through line 1 to a fractionating tower 10 to which the entrainer is admitted through line 2. The ternary vapour mixture taken off overhead is condensed in condenser 5 and passed to a separator 7 from which the upper phase comprising the entrainer, some alcohol, but little water, is refluxed to the tower 10 through line 8, while the lower aqueous layer is removed through line 9 for separation of its alcohol and entrainer contents. The dehydrated alcohol is recovered through line 11. The water layer is separated by distillation in tower 14, the alcohol and entrainer being recovered overhead and returned through line 15 to tower 10. Alternatively, the aqueous layer may be passed to a vessel 19 to which a small quantity of water is supplied through line 20 and the mixture passed to separator 22 where an upper layer of entrainer separates and is returned through line 23 to column 10.' German Specifications 142,502 and 287,897 are referred to.

IPC: F16H15/12
Filed: 1921-01-14
Abstract: 179,979. Blake, E. G. Jan. 14, 1921. Variable-speed friction gearing.-A variablespeed friction gearing and arrangement of prime movers for motor vehicles, motor boats, &c., comprises a pair of internal-combustion engines 1, 2 running in opposite directions and mechanically coupled to run synchronously, the crank-shafts being disposed transversely of the frame or chassis and the fly-wheels 8, 9 facing each other and driving a single friction wheel 11 feathered upon the driven shaft 10. The engines are mounted on cradles 15, 16 pivoted at 17, 18 to the frame 3 and guided thereon bv studs and slots 19, 20, springs 21, 22 normally forcing the fly-wheels against the friction wheel, the periphery of which is provided with a resilient facing 14. The flywheels are simultaneously released from frictional contact with the wheel 11 by wedge bars 34, 35 operated through clutch pedal mechanism and adapted to be projected between the cradles and rollers 36, 37 carried by the frame. The fly-wheels are coupled by wheels 23, 24 mounted freely on the shaft 10 and having pegs 25, 26 engaging apertures in the peripheries of the flywheels. The spindle 28 of the wheel 23 may be formed for engagement by the usual starting handle. The engines may be located at the forward or rear end of the frame and in the latter case may drive direct on to the differential gear. In a modification, the driven shaft does not extend past the centre-line of the engines and the bosses of the fly-wheels are coupled by forked shafts carrying bevel-wheels each engaging a bevelwheel on the starting-handle shaft and another bevel-wheel running freely on a sleeve thereon. The reverse is obtained by moving the fly-wheels away from the friction wheel and moving the latter so that the face thereof engages a plate clutch carried by the starting handle-shaft. In a further modification the engines are fixed and run in the same, direction and the crank-shafts are coupled bv an intermediate shaft carrying a friction bevel-wheel. The fly-wheel of one of the engines is carried by a pinion rotatably mounted on the sleeve of a pinion splined on the crankshaft and is driven by the latter pinion through intermediate gearing to rotate in the opposite direction to the other fly-wheel. The whole of the gearing driving the first fly-wheel is carried by a plate rotatably mounted on a boss on the engine cradle and having a cam-surface engaging the boss. The plate can be rotated from suitable clutch pedal mechanism to move the flywheel axially into or out of engagement with the friction wheel; a spring disposed between the fly-wheel and the bevel friction wheel on the intermediate shaft keeps the cam-surface against the boss on the engine cradle. Reverse is obtained by taking the slidable fly-wheel out of engagement with the friction wheel and sliding the latter until an inclined surface in the face thereof engages the bevel friction wheel on the intermediate shaft.

Title: Improvements in or relating to process and apparatus for manufacturing wool-like artificial filaments
IPC: D02G1/02
Filed: 1946-01-22
Abstract: A process for the manufacture of wool-like artificial filaments comprises the transfer under twist of a wet pre-impregnated regenerated cellulose filament such as is produced by the viscose or cuprammonium processes, from one twister to a second rotating in the opposite direction (both twisters imparting a false twist to the filament) and drying the filament during the transfer and preventing its exposure to any material sliding friction.  The two twisters and the inlet and outlet openings in the drying device for the filaments should be accurately aligned to prevent the filaments from rubbing against the walls of the said apertures. The twisters may comprise an inner rotating part for twisting the filaments and an outer stationary part in which the other part rotates.  The pre-impregnation may take place by means of water, or more advantageously, by means of aqueous solutions of pre-condensation or prepolymerization products which on drying will form the condensation or polymerization product within the filament, such as a ureaformaldehyde condensation product.  The two twisters may rotate at different speeds, and in this case the second should run at a higher speed than the first.  Both may for convenience be driven from the same driving shaft using suitably selected drive discs.ALSO:A process for the manufacture of wool-like artificial filaments comprises the transfer under twist of a wet pre-impregnated regenerated cellulose filament such as is produced by the viscose or cuprammonium processes, from one twister to a second rotating in the opposite direction (both twisters imparting a false twist to the filament) and drying the filament during the transfer and preventing its exposure to any material sliding friction.

[Also in Division G3] In a machine for making rubber soles, an electric motor 1 drives a pump which injects material through a nozzle 11 into moulds 10 which are brought up to the nozzle in succession. The running-time of the motor is controlled in accordance with the arrangement of markings, such as metallic studs 12 on the underside of the mould, which represent a code for the quantity of material that the mould can hold. As shown, proximity or contact-making transducers 6<SP>1</SP>, d<SP>1</SP>,f<SP>1</SP>, lie opposite studs 12 and supply signals to OR-gates b, d, f. The motor 1 drives a disc 2 having teeth 3 associated with a slot transducer 4 which produces pulses as the motor rotates and applies them through a shaper 6 to the first stage Za of a counter chain Za-Zf. Signals appear at the outputs of OR-gates b, d, f, due to the signals from the transducer b<SP>1</SP>, d<SP>1</SP>, f<SP>1</SP>, and, as soon as signals are applied to the second inputs of all the OR-gates a, c, e, from the corresponding stages of the counter chain, all inputs of an AND-gate are occupied by signals. This gate then responds to stop the motor after a predetermined number of pulses have been delivered from the shaper 6. The stages of the counter chain may be constituted by bi-stable multi-vibrators, or a decimal system involving counter tubes may be used. The pulses supplied to the counter chain may be taken from a separate generator in synchronism with the motor, and metallic fibres may replace the studs 12.
