Title: Mooring device for v.t.o.l. aircraft
IPC: B64F1/12
Filed: 1962-02-12
Abstract: 969,364. Anchoring aircraft. J. V. MICHEL. Feb. 12, 1962 [March 11, 1961], No. 5324/62. Headings B7G and B7W. Means for anchoring a V.T.O.L. aircraft, such as a helicopter A, Fig. 1, equipped with floats 1, comprises a horizontal grid B mounted on a landing platform such as a ship's deck, and a hooking means on a support C on the aircraft adapted to engage one or more bars 5 of the grid B, the support being capable of being urged downwardly of the aircraft to engage the grid, and upwardly to force the aircraft against the grid or to pull the support above the level of the landing gear. As shown in Fig. 3, two hooks 16 are pivoted at 17 on a plate 18 mounted on the rod 8 of a piston 6 in a cylinder 7, the chambers 9, 10 of the cylinder being connectable one to a gas turbine engine compressor tap 14 and the other to an atmosphere discharge port 15, through valve 13. The cylinder is mounted in the airframe by a pivot 49 and is surrounded by an annular elastic centring ring 53. Plate 18 also supports an elastomeric guide 50 which is of elongated vertical section. The plate is pivoted on rod 8 at 52, see the enlarged view of Fig. 2a, and is rotatable about a vertical axis with respect to the rod on bearings 59, being urged to a datum angular position by a spring 60. During flight, the apparatus is in the position of Fig. 3, with the hooking means held retracted by pressure in chamber 10. For landing, valve 13 is changed over by an electric motor or solenoid 67, operated manually by a multiposition switch 39 on the cyclic pitch lever 2, or automatically by a switch 68 closed on setting the collective pitch lever 3 to a predetermined low pitch setting. The hooking means is extended towards the grid, the guide 50 penetrating between two bars, and as it does so, rotating plate 18 and swinging the cylinder about pivot 49 if necessary, so as to locate the heels 20 of the hooks (Fig. 2a) over two bars, with the pivots 17 parallel to the bars. As the heels contact the bars, the hooks are pivoted to engage the bars, and locked by rollers 21 urged into notches 35 in the hooks by a spring 34 acting through a rod 33 and linkwork 31, 27, 26, 23, and 22. This displacement of rod 33 makes contacts 70, 71, to light an indicator 75, Fig. 3, showing hooks engaged, and to change over valve 13, admitting compressed air to chamber 10 to draw the helicopter down on to the grid. At take-off, the hooks are released by a solenoid 37, Fig. 2a, energized by switch 39, and acting on an armature 38 on rod 33, or by a manual release 43 acting on the rod. When in its fully retracted position, the piston 6 actuates a switch (not shown) to light an indicator 74 (Fig. 3). The automatic hook extending switch 68 can be rendered inoperative by a manual switch 73 when a landing is to be made without the anchoring device.

Title: Process for recovering acetylene from acetylene-containing gases
IPC: C07C7/11
Filed: 1938-02-19
Abstract: 511,848. Separating gaseous mixtures. RUHRCHEMIE AKT.-GES. Feb. 19, 1938, No. 5326. Convention date, Feb. 20, 1937. [Class 1(i)] [Also in Group IV] A modification is described in a known process for recovering acetylene from gases containing it by washing with water, in which process (1) the gas is washed with a restricted amount of water under a pressure of 10-15 atm. and at atmospheric temperature; in order to remove readily soluble impurities, (2) the residual gas is washed with a larger quantity of water at the same temperature and pressure, in order to dissolve the bulk of the acetylene, (3) the pressure on the water used in the second step is reduced to atmospheric pressure in one or more stages, whereby gases less soluble than acetylene escape, together with a part of the acetylene, these gases being recompressed and returned to the second step, and (4) the water, after the third step, is subjected to a reduced pressure not below 30 m.m., whereby acetylene is evolved. In the modified process, a part of the acetylene evolved in step (4) is recompressed, preferably after removal of carbon dioxide, and passed into the water before the latter is subjected to step (3), whereby the elimination of sparingly soluble impurities from the water is promoted, and a purer final product is obtained.

The webs also define the peripheral surfaces 21 of the loaded guide portions. The curved portions connecting the loaded and the unloaded guide portions are formed in the ends 23 of the guide element. The sectional elements may have additional peripherally extending arms 33, 35, the arms of adjacent elements abutting to enclose the bearing. Alternatively the radially outer portions of the webs may have peripheral extensions which surround the unloaded guide portions, or the webs and sectional elements may be enclosed in a metal sleeve. The halves of the guide element may be provided with interfitting projections 59 and recesses 61, and the halves may be bonded or welded together. The surfaces 25 may have axially extending grooves in which are engaged ribs projecting radially from the webs (Figs. 4, 5 and 7, not shown). Instead of profiling the ends 55 of the sectional elements to form part of the curved end portions of the paths, separate rings may be inserted.

Filed: 1936-02-25
Abstract: 468,256. Stays. THORNHILL, P. W. Feb. 25, 1936, No. 5579. [Class 65 (i)] [Also in Group XXXIII] A folding stay, particularly for use in aircraft undercarriages, comprising members 10, 11 and a jack disposed, when the stay is straightened, substantially at right-angles to the stay and having its two relatively movable parts separately connected to the members, is constructed, so that the means for connecting the extreme inner ends of the two strut members with the jack automatically lock the stay in its folded condition. As shown, a stay comprises members 10, 11 hinged, respectively, by lugs 14, 15 to lugs 18, 19 on a hydraulic jackcylinder 20. The jack-piston 22 is connected through piston-rod 23 and links 26, 27 to the abutting ends of the members 10, 11. Fluid is admitted to or exhausted from the jackcylinder through pipes 32, 34. Due to the fact that the lugs 14, 15 are disposed to one side of the axis 21 and that the links during folding of the stay pass over a dead-centre, the stay is locked in both its extended and retracted positions. The hydraulic jack may be replaced by a mechanical jack which may be operated by a fluid or electric motor. Specification 442,133, [Group XXXIII], is referred to.

Abstract: 491,156. Vacuum cleaners. HOOVER HOLDING CO., Ltd. (Hoover Co.) Feb. 27, 1937, No. 5940. [Class 8 (i)] In a vacuum cleaner, the height of the nozzle from the carpet is adjusted by a movement of the handle of the cleaner, a clutch being provided to connect and disconnect the handle and the adjusting means. The handle terminates in a bail B pivoted at B<1> the lower edge of the bail being provided with a shallow recess on which runs during sweeping movements the roller c carried by the spring-pressed lever c<1>. The bail B carries the piece E provided with a recess E<1> which forms one element of a clutch, the pin G<1>, constituting the co-operating element, being carried on a plate G, which is mounted on the wheel axle F which terminates the crank F<1>. The clutch is normally held open by the nose H<2> formed on the spring-controlled lever H engaging with a ledge G<2> on the piece G. On depression of the lever H by the foot the spring-pressed pawl J likewise carried by the lever H moves the piece G so that the pin G<1> engages with the recess E<1>. Movement of the handle then causes a pivotal movement of the crank F<1> and consequent adjustment of the wheel height through the piece G which is locked by the movement of the pawl J over a ratchet. A pivoted piece R<2>, the tail R<3> of which engages with the lip of the piece G, is provided with a scale to indicate adjustment heights. A modified form is described which allows the adjustment of the rear wheels instead of the front wheels of the cleaner.
