Patent GB-580714-A (GB)
Title: Improvements in the production of crimped filaments
IPC: D06M13/144
Filed: 1944-10-05
Abstract: Filaments having a basis of cellulose acetate are crimped by treating the loosely associated filaments with a softening liquid comprising ethyl or methyl alcohol or acetone or mixtures thereof, and a diluent therefor, subjecting them while still wet with that liquid and substantially free from tension to the action of water, and then drying them while still substantially free from tension. The treatment with water is preferably effected at an elevated temperature.  The softening liquid may be aqueous ethyl alcohol of 50-95.5 per cent strength, aqueous acetone of 20-80 per cent strength, an aqueous solution of acetone and ethyl or methyl alcohol, or a solution of ethyl or methyl alcohol or acetone in an inert organic liquid such as benzene, toluene, xylene, or a paraffin hydrocarbon.  After the softening treatment the excess of liquid is removed, e.g. by centrifuging and the filaments are immersed in water at 60-212 DEG  F.  The filaments may be dried while supported on screens or racks in a chamber through which hot air is circulated; or they may be dried in a rotary drier.  Continuous filaments or cut fibres may be treated.  The filaments may be dry-spun filaments which have not been subjected to any tension or draw-down during the spinning operation.  The treated filaments have a crimped or crinkled appearance like wool.  They are resilient and recover their structure even after the prolonged application of pressure.  Specification 548,112 is referred to.

IPC: B64C27/16
Filed: 1929-06-21
Abstract: 315,401. Oehmichen, E. July 13, 1928, [Convention date]. Helicopters; propelling; steering.-For propelling and steering a helicopter having a single lifting screw or a series of lifting screws with a resultant unbalanced torque, a series of propellers is provided, in s plane passing through the centre of gravity of the machine and perpendicular to the lifting axis, the thrust of which can be varied to produce an appropriate counter torque for varying and maintaining the orientation of the machine and also to give, when required, a resultant thrust to produce translational motion. The propellers may be of variable pitch or driven at variable speeds. Fig. 4 shows diagrammatically two such propellers p<1>, p<2> of variable, pitch driven by belts t' from the main engine Mo, and mounted on arms b<1>, b<2> extending from the body of the machine. The pitches of the two propellers are varied in the same or opposite senses by connections to a differential gear d<1>, d<2>, s, the pinion s being mounted on a shaft having a, lexer lm connected to a bar di for producing variations of pitch in the same direction. Differential variation of pitch is produced by turning a hand-wheel V, a propelling resultant being produced when the thrusts of the two propellers are unequal. A modification is described in which the differential gear varies the speed of the propellers by moving rollers keyed to the propeller shafts across the faces of friction-driving discs. The bar di may be connected also to a rear rudder. Fig. 6 shows a modification in which the pitch-control cables are passed around a drum ta provided with a hand-wheel V on a shaft o which can be moved bodily by a lever l<1>, return springs rs<1>, rs<2> being provided on the cables. An arrangement is described wherein the thrust of a constantly driven propeller is balanced or unbalanced by two variable thrust propellers similar to those already described. Any number of propellers may be used provided they can be controlled to give a balanced or unbalanced resultant.

Abstract: 846,751. Controlling vehicles. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd., and KERSHAW, J. W. G. June 20, 1958 [June 20, 1957], No. 19472/57. Class 79(5). [Also in Group XXXIV] A deadman's valve or switch 2 at the back rest of a vehicle driver's seat is normally depressed by the driver but is released to automatically apply the brakes. On release, a spring 1 closes atmospheric valve 4 and opens valve 3 to admit compressed air from line 6 to chamber 16 of emergency valve 5, to move a piston 12 against spring 13 to close atmospheric valve 11 and open inlet valve 10 to supply compressed air from chamber 21 to the brake cylinder 19 via double check valve 15, the flow of air to emergency valve 5 being delayed by a choke 22 and a chamber 23 so that should the deadman's valve 2 be accidently released the driver can re-operate the valve to prevent operation of emergency valve 5. Compressed air flowing to chamber 16 operates a switch 24 to operate a warning buzzer, and a switch 26 may be included between valves 15 and 5 to sound a horn on brake application. The automatic braking arrangement can be rendered inoperative by locking a valve 14 in a closed position by a lever 8, the closure of valve 14 being indicated by flag 9. The brakes are normally applied by a pedal operate valve 20 through the double check valve 15; the valve 15 may be omitted and the foot valve 20 connected to the atmospheric port 18 of emergency valve 5, Fig. 2 not shown. In Fig. 3, not shown, for electrical control, the deadman's valve is replaced by a switch, release of which energizes a solenoid controlled valve for supplying pressure to the emergency valve. In another arrangement, Fig. 4 not shown, the deadman's valve when released, cuts off a supply of pressure to the emergency valve, pressure in the emergency valve being vented via a cancelling switch and a pneumatic horn, the valve being operated to supply compressed air to the brake cylinders. Apparatus may be included in the above arrangements to cut off fuel supply and/or the ignition, release the clutch or move the gear to neutral, when the emergency valve operates; also the cancellation device (valve 14 in Fig. 1) may be operated and/or rendered effective by operation of the vehicle hand-brake. The driver's back rest may be hinged at the lower end to operate a deadman's switch when it pivots forwards.
