Title: Process and apparatus for moulding articles
IPC: B29C35/00
Filed: 1975-10-16
Abstract: 1501747 Injection moulding integral skin foam articles SCHLOEMANN-SIEMAG AG 16 Oct 1975 [19 Oct 1974] 42424/75 Heading B5A Integral skin foam articles are injection moulded by injecting unfoamed material containing blowing agent into a closed mould to fill the mould cavity, causing or allowing an unfoamed skin to form, transferring a portion of the material within the skin to a storage chamber to thereby allow the transferred material and the remaining core material to foam, compacting the transferred material in the storage chamber, and in the next cycle injecting the compacted material with a further charge of unfoamed material so that the compacted material is completely encased by the fresh material. Plasticized material is fed past a non-return valve 3 into an injection cylinder 1 from which it is injected by a ram 4 through an outer nozzle 12. A control member 11 in the nozzle 12 contains a sleeve 14 which is slidable to close the nozzle after injection by means of cylinder 16 acting through a transverse slide 15. A cranked rod 18 is moved within the slide 15 by a cylinder 19 to retract a closure needle 17 within the sleeve 14 after formation of the skin to allow material to flow out through the sleeve into storage chamber 24. A piston 25 is displaced by the incoming material against a fluid pressure in a second chamber 28. After closing the sleeve 14 the piston 25 is used to compact the material in the chamber 24 ready for injection simultaneously with the material from cylinder 1 in the next cycle, the sleeve 14 acting as an inner nozzle to confine the compacted material within the fresh material. Alternatively the compacted material may be injected between two injection stages of the fresh material. In another embodiment (Fig. 6, not shown) an injection cylinder (1a) and a storage cylinder (23a) are arranged in parallel on either side of the nozzle axis, and the end of the sleeve is connected directly to a coaxial operating cylinder (16a).
Patent GB-425009-A (GB)
Abstract: 425,009. Controlling aircraft; steering ships; gyroscopic apparatus. SCHNEIDER & CIE, and FIEUX, J., 42, Rue d'Anjou, Paris. Sept. 14, 1934, No. 26454. Convention date, Dec. 1, 1933. [Classes 4 and 114] [See also Group XX] In direction control apparatus for air or marine craft or navigation instruments of the kind in which a reference gyroscope directly regulates the distribution of fluid to the surfaces of a servomotor piston controlling the rudder &c., an additional distributing passage is provided for each face of the piston and is controlled from the gyroscope through the intermediary of a friction coupling, such control being responsive to the change in direction of the vessel &c., at the termination of each yaw. In the construction shown the gyroscope comprises the usual horizontal and vertical pivoted frames 2, 3, Fig. 2, and the rotor 1 is driven by compressed air admitted through a pivot 9 to the nozzle 7. Integral with the main supporting frame 8 is the servo-motor cylinder 41, to the chambers of which on each side of the piston 44, Fig. 3, compressed air is admitted through passages 47, 48, 53 or 47<1>, 48<1>, 53<1>, and from which exhaust takes place through two sets of passages on each side, viz. :-52, 51 or 53, 49, 50, and 52<1>, 51<1> or 53<1>, 49<1>, 501. Connection between the passages 49, 51, 52, 53 is controlled by a sliding valve 13 directly actuated from the vertical frame 3 of the gyroscope through a counterweighted lever 11, Fig. 2, while connection between the two sets of passages 47, 48 and 49, 50 is controlled by two sliding valves 23, 24 actuated by the horizontal arms 21, 22 of a pivoted frame 18, Figs. 1 and 3, which in turn is rocked by movement of a friction plate 14 integral with the frame 3 through the medium of a coacting friction finger 15 at the end of a lever arm 17. Thus, on any deviation of the vessel &c., from its course arising, compressed air is admitted to the appropriate side of the piston 44 through, say, the passages 47, 48, while the passages 49<1>, 50<1> and 52<1>, 51<1> are free to exhaust; immediately the vessel commences to return to its course, the valves 23, 24 are again actuated through the friction coupling 14, 15, allowing the previously admitted air to exhaust through the passages 49, 50. The actual control of the rudder, &c., is effected through piston rods 45, 46, fitted with restoring springs 64, 65, Fig. 7, and connected through links and levers 66, 67, 69, 70 to a rocking lever 71. Gyroscopic apparatus. Precession of the gyroscope is corrected as regards the frame 2 by means of a jet of air directed from a nozzle 54, Fig. 1, upon a vane 5 mounted upon the frame 2, and as regards the frame 3 by the differential frictional effort exerted upon the rotor 1 either by permanently adjustable friction arms 29, 30, Fig. 1, or by friction arms 35, Fig. 2, pivoted at 34 and controlled by the pilot by means of press-buttons 39.

Title: Magnesium based alloys
IPC: C23C8/08
Filed: 1973-09-13
Abstract: 1465687 Magnesium based alloys MAGNESIUM ELEKTRON Ltd 13 Sept 1974 [13 Sept 1973] 43032/73 Heading C7D The strength and other metallurgical characteristics of Mg-based alloys, especially those containing at least one of Zr, Th and the rare earth elements including yttrium together with up to 10% Zn, may be significantly improved by the introduction of hydrogen into the solid alloys by diffusion at temperatures of 400C to the alloy solidus. The rate of hydrogen diffusion may be accelerated by heat-treatment at an elevated temperature in the presence of moisture which is reduced during treatment. The alloy may be heat-treated at temperatures up to 20 C of the solidus, preferably at about 480 C, in a controlled hydrogen atmosphere containing water vapour, added by passing the hydrogen over or through water or ice or an aqueous solution of an inorganic salt or ethanol, to give a specific moisture content, expressed as a dew point temperature, which should be not lower than -20 C at the start of the process and should be lowered to -40C or below as the treatment progresses. This "wet" followed by "dry" hydrogen atmosphere is shown to improve the rate of hydrogen penetration into the alloy. Typical alloys contain 4¢%Zn, 1% RE and Th and 5¢% Zn, 1¥% Th and Zr are hydrided at 500-510C while other examples containing 5¥% Zn, 2¢% RE and 0À6% Zr are hydrided at 480C. Treatment of the alloys with chromic acid prior to heat-treatment improves the rate of penetration.
