[Also in Group XXXIII] In a fight refuelling apparatus for aircraft a rearwardly extensible flexible hose is mounted on a reel which is connected to a fixed point of the aircraft by resilient means, comprising a spring device and a train of gears of high ratio such that a small angular movement of the gear connected to the spring device corresponds to a large angular movement of the reel and extension of the hose progressively loads the spring device, a drogue mounted on the trailing end of the hose furnishing sufficient drag additional to that of the hose itself to ensure full extension of the hose against the effort of the spring device, a motor for reeling in the hose and controllable means for coupling and uncoupling said motor to and from the reel. A reel 13 carrying a refuelling hose 10 is supported in bearings 14, 15 respectively carried by a mounting plate 16 and a gear housing 17 rigidly supported by brackets 18 in an aircraft. The end of hose 10 attached to the reel communicates through an internal cavity 21 in the reel, a rotary seal 22 and a pipe 23, with the fuel tanks of the aircraft. One bearing shaft of the reel is extended by a stub axle 24 having a pinion 25 fast therewith and a larger gear wheel 29 mounted on bearings 30. The pinion 25 meshes with four planetary gears 26 mounted in overlapping relationship on axles 27 in the gear housing 17 and each gear 26 is fast with a pinion 28, all of which mesh with the gear 29. A crank plate 31 is secured to the gear 29 and has two crank pins 32, 32a to which are attached the plungers 33, 33a of a pair of liquid spring units 34, 34a pivoted at 35, 35a to the outer face of the gear housing 17. The reel 13 carries a worm wheel 36 which meshes with a worm 37 driven by an electric motor 38 pivotally mounted on the plate 16. A further pivot on the motor is connected to an electric actuator 43 by means of which the worm 37 may be engaged or disengaged from the wheel 36, the motor being used to wind in a trailed hose. When a refuelling manoeuvre has to be performed the hose 10 is drawn off the reel 13 by its own drag and the drag created by a drogue attached to its end, the units 34, 34a being fully compressed when the hose is fully extended. When the coupling between the two aircraft is made the pilot of the following aircraft causes his aircraft to close on the tanker so that the length of hose paid out corresponds to a predetermined minimum loading of the units 34, 34a, and refuelling is commenced. The use of positive stop means to prevent excessive overloading of the resilient means and excessive payout of the pipe and the provision of emergency hand cranking gear are referred to. Specification 676,430 and U.S.A. Specification 1,881,952 are referred to.

Title: A process and apparatus for the manufacture of articles from fibrous material
IPC: D21J3/00
Filed: 1965-02-24
Abstract: 1,075,814. Pulp moulding. LES FORGES DE ZEEBRUGGE S.A. and I. G. NADEL. Feb. 24, 1965, No. 7877/65. Heading B5A. A process for manufacturing moulded fibrous articles comprises preparing a suspension of fibrous material, bonding agent and chemical additives in a liquid medium, agitating the medium to evenly distribute the fibres, immersing a hollow plunger connected to a source of vacuum into the medium, whereby a felt of fibrous material is drawn on to the faces of the plunger, then removing the plunger and releasing the vacuum. The wet preform of fibrous material is then removed from the plunger and moulded under heat and pressure before dipping in a second bonding liquid and drying and curing the dipped fibrous mass. The suspension is prepared from an aqueous slurry containing combustible and/or propulsive fibres, e.g. filamentary nitro-cellulose, the denier per filament not being greater than 400, whilst the nitrogen content of the nitrocellulose lies between 11À5 and 13À35%, said slurry also containing chemical additives and a bonding agent. The propulsive fibres may be fibrous nitrated cellulose, nitrated cotton or nitrated wood pulp cellulose. In an example sulphate wood pulp cellulose is beaten in a fibre beater (1), added to an aqueous slurry of nitro-cotton fibres in a stock chest (2) and blended therein by an agitator after which diphenylamine in a methanol solution (chemical additive) is slowly added along with an aqueous emulsion of polyvinyl acetate. The slurry is transferred to a tank of water and a hollow plunger, made of perforated material covered with wire mesh, and connected to a vacuum source, is immersed therein. When sufficient fibres are deposited on the die it is removed from the tank, covered with a flexible rubber sheet and the vacuum replaced by slight intermittent pressure applied to the inside of the die to slightly expand the wet felt so that it can be removed from the die as a hollow preform. This is then placed in a steamjacketed heated die, and compressed, dried and moulded to final shape in a drying press (6). The die is connected to a vacuum source to assist in removing water from the preform and also to allow it to be dried at a reduced temperature and pressure. The moulded article is then impregnated with a solution of polystyrene in toluene, dried and finally trimmed. Articles manufactured by this method include cartridge cases and ignition tubes.

IPC: D06C21/00
Filed: 1957-03-11
Abstract: 844,452. Finishing fabrics; rollers. BRADFORD DYERS' ASSOCIATION Ltd. March 4, 1958 [March 11, 1957], No. 7955/57. Drawings to Specification. Classes 42 (1) and 42 (2). In a process of compressive shrinking, wherein the fabric to be treated is pressed into contact with one or two heated metal surfaces, the surface of the or each metal surface is engraved with parallel Schreiner lines in such a manner that the lines impressed on the fabric extend in the direction of travel of the fabric, thereby reducing the glazing effect which normally results when a fabric slides over a heated surface. As particularly described, the fabric is shrunk by passing between a heated roller and a contractible belt, and is finally passed through a Palmer dryer, the surface of the roller being engraved with Schreiner lines running round its circumference in parallel planes all perpendicular to the axis of the roller. Alternatively, it is not necessary to engrave the whole surface with such parallel lines, and the engraving may be in the form of a pattern, thereby producing a patterned effect on the fabric. The glazing of the fabric may be further reduced by subjecting the fabric to a steaming action after it leaves the shrinking apparatus and before it enters the Palmer dryer.
