Title: Servo-brake
IPC: F16D57/06
Filed: 1924-10-09
Abstract: 223,897. Fabrique Nationale d'Armes de Guerre, Soc. Anon. Oct. 22, 1923, [Convention date]. Fluid-pressure. - A liquid-operated brake for vehicles comprises pump gears 5, 6 surrounded by a casing 8 connected by an arm 12 to the brake rigging and located in a chamber 1 containing oil &c. The casing 8 is rotatably mounted on the shaft 4 which drives the gear 5 and the shaft is driven from a moving part of the vehicle. Normally the pump gears draw oil into the casing 8 through an aperture 9 and deliver it through an outlet 10. When, however, a cylindrical valve 11 carried from the shaft 4 by a sleeve 14 is moved by a fork 15 to restrict or close the outlet 10, pressure is developed in the casing 8, which opposes the action of the pump and thus causes the casing 8 to rock in an anticlockwise direction, Fig. 1, to apply the brakes. A safety valve 13 is provided to limit the pressure developed in the casing 8 and therefore the braking pressure. The shaft 4 may be disposed vertically and the arm 12 connected to the casing 8 then be located outside the chamber 1, whilst a second pump rotating in an opposite direction from the first may be provided to effect braking when the vehicle is moving backwards, the valves of both pumps being subject to a single control member.

Title: Process for the separation of one or more constituents of liquid mixtures
IPC: B01D3/34
Filed: 1922-09-06
Abstract: 204,196. British Cellulose & Chemical Manufacturing Co., Ltd., and Bader, W. Sept. 6, 1922. Acids &c., distilling.-Volatile constituents of a liquid mixture are separated by heating the liquid to a temperature below its boiling-point while it is covered with a thin layer of a liquid, such as oil, which floats upon and is immiscible with the liquid, and preferably has a higher boiling point, and continuously removing the vapours by a gas or air current passed over the surface. The composition of the vapours is determined mainly by the solubility of the constituents in the oil. The gas or air may be used as heating-agent for the liquid, and it may be cooled, compressed, or liquefied to separate the vapours. As applied to the distillation of dilute acetic acid, the liquid is passed in succession through trays 1 from an inlet pipe 2, through overflow pipes 5, to an outlet pipe 6, and the surface of the liquid in each tray is covered with a thin layer of a high-boiling petroleum distillate, for example, spindle oil. Air from a blower 7 is passed through a heat exchanger 8, and over a radiator R which brings its temperature to about 100‹ C. and then in succession through the horizontal spaces between the trays, radiators R<1> - - R<5> being used to maintain its temperature at about 100‹ C. The vapour-laden air passes through t"he heat exchanger 8 to a condenser 10 and is returned to the blower 7. In treating acetic acid of 30 per cent strength a distillate of 60 per cent strength is obtained. A second treatment will yield acid of 80 per cent strength and a third treatment acid of 92-95 per cent strength.

Title: Method of producing mixtures of different denier filaments or fibres
IPC: D01D4/02
Filed: 1959-07-14
Abstract: Mixtures of filaments or fibres are produced by feeding viscose into a spinning bath through at least two spinnerets each having different numbers of apertures, the rate of feed to the spinnerets being the same, the filaments or groups of filaments of heavier denier being spun from at least one spinneret the total aperture cross-sectional area and the diameter of each aperture of which are greater, respectively, than those from which the other denier(s) are spun. All the filaments are drawn off at the same rate, whereby those of heavier denier are subjected to a greater stretch than the others, so that the crimping properties of the filaments of different deniers are substantially equalized or brought nearer to each other.  The spun filaments or bundles thereof are combined to form a rope which is then treated and dried, or stretched and cut into staple lengths, which are then finished.

Each plane comprises sticks 13 covered with fabric or paper and each stick has centrally clamped thereon a mortised block 14. The fuselage sticks 18, 19 pass through the blocks and through holes in vertical spacing members 21, and at their front ends abut against U-shaped clips 16, Fig. 4, which have T-shaped ends held by the blocks 14. The rear ends of the members 18, 19 pass through similar mortised blocks 29 on the horizontal rudder sticks 27, their ends abutting against a wide clip 30. The wire frame of the vertical rudder has ends which engage holes in the blocks 29, and is held in place by cords 34. A cord 31 connected to the top of the rear stick 21 passes through a screw-eye on the front rudder stick 27 and is connected to the bottom of the said stick 21. Paper or fabric is pasted round the cord 31. Brace and stretch rods 35, 36 space the outer ends of the main planes, the brace rods 35 holding the rods 36 in place. Cords 37 connect the upper rear ends of the brace rods and the front ends of the rudder 28, and the outer ends of the cords 39 on which the auxiliary planes are formed are connected to the brace rods to hold them in place. Cords 40 prevent curvature of the planes 38. The tension of a diagonal cord 48 between the main planes can be varied to stagger the main planes and to give them an angle of incidence. The kite is flown by means of cords 45 connected to the outer ends of the lower planes 12, a cord 44, 46 connected to the rudder, and an operator-control cord 43. When the cord 43 is taut, the cords take the position shown in Fig. 1, the part 46 being pulled into alignment with the cord 43. The best length for the cord 46 is stated to be 4 inches. A propeller 41 pivoted to the front stick 21, is apertured at 42 so that in flight the propeller gives a whirring sound. The Specification as open to inspection under Sect. 91 (3) (a) comprises also provision for adjusting the lengths of the cords 39 of the auxiliary planes in order to curve the main planes. In addition the rear ends of the members 18, 19 pass through holes in metal fittings 30, Fig. 1 (Cancelled), through ears 33 on which and between the members 18, 19 pass the horizontal rudder sticks 27. A W-shaped clip 39, Fig. 8 (Cancelled), passes round the ends of the members 18, 19 and inside the stick 27 to hold the fuselage members in place. In this modification the cord 31 is passed through a wire fitting 36 pivoted in the ears of the fitting 30. This subject-matter does not appear in the Specification as accepted.
