Abstract: 897,940. Making pipes. CARTWRIGHT, W. L. March 3, 1961 [March 8, 1960], No. 8109/60. Class 99(2). In a method of manufacturing fibre reinforced resin tubing, resin impregnated fibres 1 are drawn longitudinally over a mandrel 10 and further resin impregnated fibres 13 are helically wound on top of the fibres 1, the motive force for drawing the fibres along the mandrel and through a curing oven being applied mainly through the longitudinal fibres. As shown, glass fibre rovings 1 are led through a resin bath 2, passed through a thermostatically controlled pre-heating chamber 6 and by means of guide plates 7 and 8 and a temperature controlled die 9 the rovings move longitudinally along a mandrel 10 supported on plates 7 and 8. The die 9 and the mandrel 10 may have a P.T.F.E. liner 11. The rovings are finally cured in a muffle seating chamber 12 and the tube 16 so formed is helically wrapped with resin impregnated glass rovings 13 by means of a rotating disc 13. The built up tubing is then wrapped with " Cellophane 19 " (Registered Trade Mark) until it is finally cured on passing through a muffle heating chamber 20. Successive layers of longitudinal and helical fibres may be applied and/or any combination of helical windings such as crossed helices may be used.

Abstract: 100,739. Siemens & Halske Akt.- Ges. June 24, 1915, [Convention date]. Electrodes.-Wires constituting an electrode hang freely and are weighted at their lower ends. The weights, which also serve to space the wires, may be glass balls or cylinders, short pieces of capillary tubing fused on to the wires, or glass bulbs d, Fig. 2, containing shot or the like. If a single weight f, Fig. 6, is used for two or more wires, it is grooved as shown at g, or otherwise designed to space the wires properly. The upper ends of the wires mav be attached to a common conductor b, Fig. 2, or the wires may be weighted at both ends and hung over or looped around a conductor b, Fig. 6. In the latter case, the electrodes are arranged so that wires of opposite polarity are equidistant. A bipolar electrode'may be constructed by hanging wires a, Fig. 8, over an insulating-partition B. The anode part of each wire may then be of platinum or other rare metal, and the cathode part of cheaper metal. Thin horizontal wires a<1> may cross-connect the main wires. Connexions may be immersed, being protected by a coating or sheathing, or may be above the surface of the liquid and shielded from spray.

[Class 119] [Also in Group XXIX] An electrically driven recording-apparatus, e.g. a kinematographic camera, is operated synchronously with the firing of a machine gun on an aircraft by an hydraulic system. A pump 24 draws fluid from a reservoir 25 and delivers it to a valve 27 whereby the fluid may either be returned directly to the reservoir through pipes 29, 40, or delivered through a pipe 38, first to a cylinder 7 controlling an electrical contact 10, and then to a cylinder 39 controlling, through a plunger 35, the firing mechanism of the machine-gun 33. A kinematographic camera 3 is in circuit with a battery or generator 2, the lines 1 of the camera circuit having terminals 4, 5 which are bridged by the contact 10. A byepass valve 30 having a knob 32 under the control of the airman, when operated, cuts off flow through the pipe 37 whereupon, owing to a restriction 23 in the pipe 40, pressure is built up in the pipe 22 to operate the firing mechanism of the guns and to start the camera motor. The contact device 10 is constructed as a two-part cylinder 6, 7, Fig. 2, with an interposed diaphragm 13 and spring-pressed plunger 8 operating a button 42 to close the contacts 4, 5. The cylinder 7 is offset from-the line B-B of the pipe 22 with a port communicating between the pipe and the chamber 15 below the diaphragm,

Title: Magnetic core materials and their manufacture
IPC: H01F1/24
Filed: 1927-03-28
Abstract: 269,510. Standard Telephones & Cables, Ltd., (Assignees of Bandur, A. F.). April 17, 1926, [Convention date.]. Insulation. - Magnet cores, particularly for loading coils for telephone circuits, are formed of particles of a magnetic material separated by an insulating material comprising kaolin and flux. The magnetic material preferably comprises a nickel-iron alloy containing more than 25 per cent of nickel, for example 78¢ parts of nickel and 21¢ parts of iron. These ingredients are melted in an oxidizing atmosphere and poured into a mould, the resulting brittle alloy being reduced to fine particles of such a size that all will pass through a 120-mesh screen and a large percentage will pass through a 200-mesh screen. The finely-divided particles are then annealed in a closed container at from 750‹ to 980‹ C., preferably at about 925‹ C. The annealed alloy is again reduced to a finelydivided form and mixed with the insulator, which is prepared as follows. One part of kaolin is dissolved in three parts of water by heating to 95‹ C. and stirring until it forms a thin homogeneous colloidal mass. To this is added 4 per cent of the weight of the kaolin of a flux such as boric acid to lower the fusion temperature and increase the adhesive quality of the kaolin, the boric acid preferably being dissolved in the hot distilled water in which the kaolin is mixed. The powdered alloy is added to the mixture and stirred or rolled in a revolving drum, the temperature being maintained at 100‹ C. The dried insulated dust particles are then pressed into cores or rings under high pressure, and are impregnated with a solution of zinc hydroxide containing an excess of ammonia The rings are then dried at 100‹ C. ' and heated in an oven to 290‹ C. for several hours to reduce the amount of chemically combined water. They are then annealed in closed pots at about 675‹ C., partly fusing the kaolin and decomposing the zinc hydroxide to form an oxide coating on the particles. A number of the rings so formed are stacked coaxially to form a core. which is then wound with a toroidal winding. Other flux materials such as borax, common salt, or magnesium sulphate may be substituted for the boric acid to lower the fusion temperature of the kaolin.

Abstract: 372,040. Controlling change-speed gearing ; locking rods. THOMSON, B., Combe Close, Woldingham, Surrey. March 21, 1931, No. 8772. [Classes 80 (ii) and 80 (iii).] In control mechanism for change-speed gearing, the operative connection between control and striking members 1, 2, Fig. 2, is effected through a member 6 which serves to lock the striker 2, the lock being released by the member 1 in making a change. The lock member 6 is pivoted at 7 on a sleeve 4 of the striker 2, which slides on a fixed guide bar 3. The member 6 is shown as locking the striker in gear position with a dog 14 engaged with a recess 21 in the bar 3. The member 6 is held in locking position by a spring ball 28 pressing against a slope 17. In moving the striker 2 to the right to neutral, the first part of the movement of the control 1 rocks the member 6 on its pivot to disengage the dog 14. In the neutral position the member 6 is square over the bar 3 with the ball 28 engaging a medial notch 18 in its base. The member 6 slides over the bar 3 farther to the right, until another dog 15 slips into a recess 22. A modified form is shown in Fig. 4 in neutral. The bar 3 in this case slides and carries the striker, not shown. The dogs 14, 15 lock by engaging over the edges of a fixed transverse plate 32. The member 6 is releasably held in its three pivoted positions by a spring ball 36.
