Title: Improvements in or relating to panels, windows and like hinged members
IPC: E05F11/38
Filed: 1926-03-29
Abstract: 259,472. Barnes, A. R., and Barnes, A. March 29, 1926. S p r i n g hinges; pivoting- adjustments.-A hinged window, panel, or flap, more particularly for use on motor and other vehicles, is provided with a spring-controlled retaining catch comprising a pawl and ratchet device and a window closing- spring in combination with a mechanical braking device adapted to engage with a movable part of the hinge against the action of the closing spring and to be actuated in timed relation to a hand-operated releasing device for permitting the window to be closed by the said spring. In the arrangement shown in Fig. 5, the support A, of a, window, is mounted to turn on a stationary pillar against the action of a closing spring, and a slidable ratchet member F<4> is pressed by a spring F<3> into engagement with a ratchet member E on the member A. The member E is attached to a lower member with an inclined surface K that is engaged by a braking member J<3> under the action of a spring L. The window may be opened by hand against the action of its closing spring and it is held in the open position by the ratchet device E, F<4>. The rack F<4> has a stem F<5> with a projection f engaged by a cam G<2> on a hand-operated spindle H. When the rack F<4> is depressed to permit of the window moving towards its closed position under action of its closing-spring, further movement of the handle moves the cam M<1> into engagement with the end j<4> of the stem J'. The shoe J<3> serves as a brake as the window closes, and this braking action is increased as the window is nearing its fully-closed position, by a shoulder K<1> which acts upon the heel of the incline of the shoe J<3>. A modified construction is described. Specification 232,741 is referred to.

Filed: 1946-03-19
Abstract: 613,459. Automatically-adjustable couplings. BENDIX AVIATION CORPORATION. March 19, 1946, No. 8519. Convention date, March 28, 1945. [Class 80 (ii)] [Also in Group XXVII] In centrifugally-adjustable ignition timing shaft coupling a pinion 7, which is journalled upon a bearing 10 on a rotor shaft 5 and has a splined end 9, Fig. 1, that engages with a part of an interval combustion engine, meshes with the toothed segments 15 of a pair of diametrically opposed centrifugal members 18 which are pivoted upon sleeves 19, Fig. 1, the latter being pinned to and projecting from each side of a plate 11 also journalled upon the bearing 10. Pins 22, Fig. 3, in the plate 11 define the normal and maximum counter-clockwise position of the centrifugal members 18 which latter are connected by adjustable tension springs 24, Fig. 3, to the plate 11. Adjacent the left-hand side of the plate 11 and pivoted upon the other ends of the sleeves 19 is another pair of centrifugal members similar to the members 18, but differing from them in that they are of smaller mass and are subjected to a greater spring tension. Toothed segments 35, Fig. 1, on the lighter centrifugal members engage with a driven pinion 31 that is splined to the rotor shaft 5. At a given speed the pivotal movement of the centrifugal members causes the rotor shaft 5 to be moved ahead in the direction of rotation relative to the pinion 7. At a higher speed movement of the lighter members will cause a reverse relative displacement of the rotor shaft 5 and pinion 7. In a modification only one of each pair of centrifugal members is employed and these are disposed at opposite sides of the plate 11 and diametrically opposite each other. Specification 610,567 is referred to.

Abstract: 870,297. Moulding glass. GENERAL ELECTRIC CO. Ltd. March 10, 1960 [March 12, 1959], No. 8610/59. Class 56. Glass bodies each having one shaped surface are produced by placing glass charges in shaped recesses, having surfaces not wetted by molten glass, in holders which are then placed in a centrifuge, with the mouths of the recesses facing inwards, the centrifuge being heated to glass melting temperature and subsequently cooled while still being rotated. The holder 13, Fig. 6, has a number of recesses 14 and holes 16 in which wires 17 are placed. The charge of glass is in the form of a length of tubing or a sintered bead. The wires 17 may have a coefficient of expansion such that they become fused into the glass body or may be of a material, for example copper, having a coefficient of expansion greater than that of glass so that they can subsequently be removed. They may be tapered to facilitate this. The form shown provides recesses in which frusto-conical projections are cast about the holes so produced to provide for subsequent fusion of wires through the holes. The centrifuge shown in Fig. 7 comprises an annular silica tray 18, on a shaft 22 driven by a motor 24, enclosed in a furnace 21 with a lid 33 operated by a pneumatic cylinder 32. The holders 13 are placed within the tray against the outer upturned side 20. The tray has a silica lid 26 with spokes 28 connected to a hub 27 fitting on the shaft. As the centrifuge is heated by gas burners 38 nitrogen or other inert gas is fed from a pipe 44 and a gland 34 through a duct 35 within the shaft 22 to a manifold 36 and thence to holes 37 in the silica tray.

Filed: 1945-04-07
Abstract: 589,995. Sewing-machines. SINGER MANUFACTURING CO. April 7, 1945, No. 8646. Convention date, Jan. 1. Drawings to Specification. [Class 112] Lock-stitching by hooks; presser-bars; frames. -In order to improve high-speed stitching by reducing the pressure of the under-thread against the needle-hole in the throat-plate and thus its friction against the needlethread and the resistance to feed of the work, the needle-bar of a straight eyedneedle machine is inclined so that the descent of the needle has a forward component; the needlehole can thus be more nearly above the rear edge of the bobbin-case, from which the underthread emerges, while the needle still passes through the axis of the loop-taker. The presser bar is substantially parallel to the needle-bar. The whole standard and arm of the machine may be inclined, thus facilitating inspection of the work, or the inclination may be confined to the head or to the guides for the needle-bar and presser bar. Feed by dogs.-In order,to provide additional clearance near the loop-taker in the usual fourmotion feed mechanism comprising arms on two horizontal rock-shafts, the feed-lift rock-shaft carries a forked arm engaging a block on the feed-bar, instead of the usual arrangement in which the feed-bar is forked. The arm on the feed rock-shaft is arranged so that it never reaches the vertical position, the rear-end of the feed-dog being thus made to rise before the front end and to drop quickly near the end of the feeding movement. ' Upper and lower shafts, connecting; lubricating.-The two shafts are bevel-geared to a vertical shaft, the gearing giving a two-to-one ratio. The bevel gear on the lower shaft also engages a bevel gear on the shaft of a rotary oil-pump which supplies the bearings of the machine. Specification 452,001 is referred to.

Title: Improvements in method of refining waxes
IPC: C10G73/42
Filed: 1949-04-01
Abstract: Crude waxes, particularly for candles, are refined by heating the wax in the presence of an acid activated alkaline earth mineral for a period of time and at a temperature and pressure sufficient to precipitate therefrom the impurities naturally present therein, and thereafter removing therefrom the precipitated impurities.  Colour, odour-imparting bodies and other impurities are thus removed from the waxes, which are also stabilized.  A calcination activated alkaline earth metal oxide may be mixed with the acid activated mineral so as simultaneously to saponeify fatty oils present and increase the melting point of the wax.  Beeswax is particularly referred to.  The alkaline earth mineral specified comprises Montmorillonite (Mg Ca)O.Al2O3 5 SiO, n(H2O) which may be mixed with small proportions of Montronite (Al2Fe)2O3, 3 SiO2n(H2O) and Saponite, 2 MgO, 3 SiO2n(H2O), which mixture is found naturally.  The mineral is preferably activated with hydrochloric acid, and preferably until it has a pH of about 4.  The purification is effected in an enclosed vessel at a temperature of about 200 DEG  to 300 DEG F., under a pressure of about 10 to 25 lbs. per sq. inch, for about 10 to 60 minutes, with mechanical agitation.  In the case of beeswax, vessels of stainless steel or aluminium alloys should be used with neoprene, a synthetic rubber, or leather gaskets.  Air may be injected into the vessel to oxidize some of the more volatile oils &c. and also steam may be passed in.  The calcination activated alkaline earth metal oxide, when used, may be activated magnesium oxide.  After the heating treatment, the wax is pumped to a pressure type filter to remove the precipitate.
