Title: Improvements relating to retractable undercarriages for aircraft
IPC: B64C25/14
Filed: 1936-12-31
Abstract: 486,211. Retractable undercarriages for aircraft. AIRCRAFT COMPONENTS, Ltd., and BOUND, R. H. Dec. 31, 1936, No. 35859. [Class 4] In a retractable undercarriage of the type in which a pivoted shock-absorbing leg is swung about the pivot for retraction by the folding of a radius rod pivotally connected to the leg, the folding means comprises a jack of which one element is pivoted to one part of the radius rod intermediate the length thereof whilst the other element is pivotally supported about the same axis as that on which the leg swings. A shock absorber strut is pivotally attached to an aircraft structure at 4, Fig. 1. A folding radius rod comprises a part 8 pivotally connected to the strut at 7 and a part 9 pivotally connected to the structure at 11 and, if desired, provided with an inter. mediate hinge 12 permitting some lateral movement during retraction. A hydraulic jack has a cylinder 5 pivotally mounted at 4 and a piston rod 6 engaging a pin 13 on radius rod part 9 by a slot 6A. A spring link capable of contraction from the dimensions shown is pivoted at one end to rod 6 and at the other to a lever 15 formed with a notch engaging a stop 16 on an extension 8A of rod part 8. Initial movement of the jack piston causes lever 15 to rock clear of pin 16 and further movement causes the end of the slot to engage pin 13 and break the radius rod. On extension, which may also be effected by the jack, engagement of stop 16 is made possible by the enforced contraction and subsequent extension of spring link 14. The radius rod and/or the leg may be constituted by a pair of parallel similar elements. When retracted substantially the whole of the undercarriage parts lie below the plane containing axes of pivots 4 and 11. Specifications 458,187 and 473,202 are referred to.

Abstract: 351,894. Incandescent arc lamps. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Nov. 28, 1930, No. 35874. Convention date, Jan. 9. [Class 39 (i).] In a gas- or vapour-filled arc discharge tube for the emission of rays, for example ultra-violet rays, comprising an incandescent cathode and one or more anodes, the anode, or at least one anode is formed of grid shape to attract particles disintegrated from the cathode and prevent blackening of the wall of the discharge tube. In the example the incandescent cathode 3 is formed by a helically wound wire, for example of tungsten, which may be coated with an electron-emitting substance, and the anodes 4 are each constituted by a wire 6 wound into the form of a grid on a frame 5. Gauze may be used in making the anodes. A few drops of liquid mercury may be contained in the tube to provide a filling of mercury vapour, and in addition a gas, preferably a rare gas such as argon, is contained therein.

Abstract: 318,804. Hamel Akt.-Ges., C., and Hamel, E. Dec. 5, 1928. Spindle-driving apparatus.-In spindle-driving arrangements wherein two pulleys for each belt are mounted on pivoted arms arranged on opposite sides of the tin roller and connected by a spring so that the belt is tensioned thereby irrespective of the direction of the drive, the arms 7, 8 carrying the pulleys 5, 6 and connected by a resilient element such as a spring 9, are mounted in supports provided with abutments so that, when the tin roller rotates in the direction of the arrow x, the arm 7 is maintained by the tension of the belt against its abutment, and the pulley 5 acts a guide and the slack portion of the belt is tensioned by the pulley 6 under the control of the spring 9. When the tin roller rotates in the direction of the arrow y, the tension of the belt moves the arms into the position shown in dotted lines and the functions of the pulleys are thereby automatically reversed.

Abstract: 1283137 Leather substitute KALLE AG 30 July 1970 [31 July 1969] 36843/70 Heading B2E Leather-like permeable multi-layer sheet materials are made by applying a solution of a polyurethane in a water miscible solvent said solution having a solids content of 5-30% wt and a viscosity at 25‹C of 500-10,000 cp, applying said solution to one surface of a web of a fibre fleece which is moving at a speed of 0.5-20 m/min, so that the fleece is partly penetrated by a part of the solution, the remainder forming a surface coating having a final thickness of 100-800 microns; applying an aqueous dispersion of a different polymer e.g. a synthetic elastomer having a solids content of 10-50% to the other surface of the fleece and allownig it to be totally absorbed therein, the water in the dispersion partially coagulating the polyurethane solution; applying a coagulating agent for the solution and the dispersion to the web; removing excess coagulating agent and solvent by washing, e.g. in water and then drying the material which has a microporous surface coating 1, a fleece zone 2 bonded by the microporous polymer, a zone 3 bonded by polymer and elastomer and a zone 4 bonded wholly by the elastomer. The fibre may be needled and may be of synthetic and/or of natural fibres. The polymer in the dispersion may be polychloroprene, polybutadiene, polyacrylates, butadiene/acrylonitrile copolymers, acrylonitrile/ butadiene/styrene copolymers, vinyl acetate/ acrylic copolymers. The dispersion may also include stabilizers, emulsifiers, plasticizers, dyestuffs and vulcanizing agents. The coagulating agent may be a mineral acid, for example hydrochloric acid or sulphuric acid, a solution of a hydrolysable salt, for example ammonium chloride or aluminium sulphate or an organic solvent such as ethanol or acetone. In an embodiment a web 7 having opposing sides 7a, 7b is coated with polyurethane solution 10 on face 7a and passed over a suction plate 12 which promotes the absorption of the solution. The web is then sprayed with an elastomer dispersion 17 on face 7b before being passed through the path 19 containing the coagulating agent 20, washed in bath 21 and dried in tunnel 23 and rolled up. The material may be used in the manufacture of upholstery and garments.

Abstract: 976,695. Hydraulic turbines and pumps. ATELIERS DES CHARMILLES S.A. Sept. 24, 1963 [Oct. 17, 1962; July 19, 1963], No. 37457/63. Headings F1C and F1T. A hydraulic installation comprising a turbine wheel and a pump wheel mounted in adjacent positions on the same shaft, a single casing being provided for feeding the turbine and receiving the water delivered by the pump, and means being provided for separating the internal space of the casing from the spaces in which the turbine and pump wheels rotate, is characterized in that a suction pipe of the turbine and a suction pipe of the pump are disposed coaxially on the same side of the wheels over at least a part of their length contiguous to the wheels. The hydro-electric installation shown comprises a turbine rotor 3 and a pump rotor 5, which may be integral with one another as shown, overhung on the shaft 1 of a dynamo-electric machine 2 and surrounded by a common spiral casing 14. When the machine 2 is acting as a generator, water from an upper reservoir (not shown) is fed to the casing 14 and passes through fixed inlet guide vanes 13 and adjustable-pitch stator blades 8 to drive the turbine rotor 3, being discharged through a suction pipe 17 to a lower reservoir 21. As shown, communication with the pump rotor 5 is cut off by an annular gate 23. At off-peak periods, gate 23 is opened and a similar gate 22 is closed to cut off communication with the turbine rotor 3. The machine 2 is then run as a motor to drive the pump rotor 5, which draws water from the lower reservoir 21 through a suction pipe 18 and discharges it through fixed diffuser vanes 16 to the casing 14 and thence to the upper reservoir. As shown, the suction pipe 18 is concentric with the suction pipe 17 over part of its length (or over its entire length, particularly in the case of an installation having a vertical shaft). The guide vanes 13 are curved to reverse the tangential component of flow, whereby the installation runs in the same direction of rotation during both modes of operation. Alternatively, the diffuser vanes 16 are curved for this purpose. The gate 22 may be omitted, its function then being performed by the adjustable stator blades 8. The common reservoir 21 may be replaced by separate reservoirs for the two suction pipes. The turbine and pump rotors (and their suction pipes) may be transposed.
