Title: Improvements in and relating to the liquid treatment of tows of regenerated protein fibres
Inventor: WORMWELL ROBERT LOUIS
IPC: D01D10/04
Filed: 1952-11-12
Abstract: In the treatment of a tow of regenerated protein fibres for a considerable time in a liquid treating bath, flotation of the tow in the bath is ensured by first treating the tow with a substantially non-volatile, water-immiscible liquid which is inert to the fibres and which has a specific gravity not greater than 1.1 so that the liquid is entrained in the fibres, and then feeding the tow in convolutions on to the surface of the liquid treating bath, allowing the tow to accumulate in the bath for a sufficient time to produce the desired effect, and then continuously withdrawing the tow at a rate substantially equal to the rate of feed by removing it from the underside of the mass of convolutions.  Preferred water-immiscible liquids are higher paraffin oils such as white oil.  The liquid treating bath may comprise a hardening liquid, an insolubilizing liquid or an esterification liquid, as described in Specification 690,492. Specifications 565,011 and 618,925 also are referred to.

Abstract: 964,617. Aircraft fuselages; driving aircraft. ENGLISH ELECTRIC CO. Ltd. July 8, 1963 [July 24, 1962], No. 28509/62. Heading B7W. An aircraft fuselage comprises a fixed cockpit 2 and a nose portion 4 hinged to the cockpit about a transverse horizontal axis 6, so that it may be drooped to increase the field of the pilot's downward vision, e.g. for landing, and the nose portion may also be swung about a vertical axis to shorten the aircraft for stowage. As shown, the nose is pivotally supported by arms 5, each working in a channel 9 so that no sealing is required between the pressurized cockpit and the nose. The latter contains a radar dish aerial 10 rotatable about axis 11. Part spherical bulkheads 7, 7<SP>1</SP> on the cockpit and nose respectively may have co-operating tracks and antifriction rollers. When drooped, e.g. by hydraulic jacks (not shown), the nose exposes windows 12, 13, 13<SP>1</SP> (Fig. 2), in bulkhead 7, so that the limit of downward vision is increased from say ten degrees below the horizontal datum to twenty degrees. A retractable panel 15 is hinged to the cockpit at 15, and on the ground may be attached to the nose by a vertical hinge so that the nose can be swung through 180 degrees after being detailed from the arms 5. Alternatively, the panel 15 may be hinged to one arm 5, which is then correspondingly shorter, and be permanently hinged to the nose. The connection between the other arm 5 and the nose is then releasable on the ground, or extensible to effect folding back of the nose. Hot air may be blown from narrow slots beneath windows 12, 13, 13<SP>1</SP> to remove rain and ice.

Abstract: 188,197. Leydekkers, W. H., and Ruddle, W. O. Oct. 28, 1921. Reel and web apparatus.-An advertising device for moving vehicles comprises a number of blinds I, bearing advertisements, mounted upon rollers D carried in discs C, C<1> secured to a centrol rotating spindle B. Each roller D has secured to one end thereof a pinion F gearing with a fixed toothed wheel G notched at H. Motion is communicated to the shaft D from the motor vehicle through a flexible shaft S, or the equivalent, toothed wheels R, Q, and a worm and worm wheel L which transmit motion to an eccentric-actuated pawl O engaging a ratchet wheel P having the same number of teeth as there are rollers. A ratchet device with small teeth is provided at T to prevent the shaft B slipping back when the vehicle reverses. Rotation of the shaft B advances the blinds to a position in which they drcp into the notch H in the wheel G. In this position each roller is disengaged from the wheel G and the blind unrolls by its own weight to display an advertisement. Further movement of tlie shaft E carries the unrolled blind forward until its roller is again engaged with the wheel G. The roller is then free to rotate as the step-bystep movement of the shaft B continues and thus the blind is re-wound. A spring, not shown, assists the re-engagement of the roller pinions F with the wheel G, and a spring J prevents the blinds unrolling until they reach the notch H.

Abstract: 249,907. Speck, T. R. Dec. 4, 1924. Muffle furnaces; charges; cooling discharged materials. - A process for annealing and tempering metals in a non-oxidizing atmosphere consists in coating the articles or containers therefor with oil or a mixture of oil and water, placing them in a loading chamber where there is sufficient heat partly to vaporize the oil, and finally passing them into the heating chamber where the vaporization is completed. A furnace for carrying out this process comprises, as shown, downwardly inclined loading, heating, and cooling chambers 3, 2, 10 respectively, the latter terminating in a hood 12 which extends below the surface of oil or oil and water in a sealing tank 11. For removing the discharged containers 15 fom the tank 11 there is provided n shoot 16 delivering on to a platform 17 carried by a winch 18 or other raising device. In starting up the furnace, the containers 15 and/or the articles are coated with oil and placed in the loading chamber 3 from which, after opening the counterweighted door 7, they are fed into the heating chamber 2 where the vaporization of the oil begun in the chamber 3, is completed, thus producing an inert atmosphere. The furnace may now be worked continuously by recharging the chamber 3 with the containers 15 which are removed from the tank 11 and thus already coated. with oil.
