Patent GB-347222-A (GB)
Title: A new or improved process of refining metals and alloys of low melting points
IPC: C22B9/02
Filed: 1930-01-24
Abstract: In the purification or separation of metals of low melting-points by heating the metal under treatment to a temperature sufficient to melt the mass but below the melting-point of alloys of the metals present as impurities with each other, the metal is filtered at a temperature at which the main mass is molten.  A metal may be added to alloy with the impurities.  Lead containing copper, tin and antimony is heated to 327 DEG  C. and the solid alloys of copper and tin, copper and antimony are filtered off.  Copper or aluminium may be added to the mass if the initial copper content is insufficient to precipitate the antimony as an alloy.  Alloys of lead and tin used as bearing metals may be purified in a two-stage process by heating the alloys to a temperature slightly above the melting-point of the main mass, filtering off the solid copper-tin alloy, and then adding aluminium to the filtrate to combine with antimony and copper and filtering off the aluminium-antimony and aluminium-copper alloys.  Aluminium or zinc may be added in the first stage to remove copper and further aluminium added in the second stage to remove antimony.  The separated copper-tin alloys may be used as bearing metals.  The filtering apparatus may comprise a cylinder of iron or other metal unattacked by the molten mass, in which a piston moves with a clearance through which the molten metal may pass.  The apparatus may also comprise a series of metal plates, assembled face to face, but spaced slightly apart.  This grid of plates is used with the edges towards the molten mass which is forced through the filter so formed. Specification 241,224, [Class 82 (i), Metals, Extracting &c.], is referred to.

Title: Improvements in jack or actuator systems
IPC: B64C25/24
Filed: 1946-01-28
Abstract: 613,129. Toothed gearing. VANCE, W. G. C., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Jan. 28, 1946, No. 2718. [Class 80 (i)] [Also in Group XXX] In a motor-driven jack or actuator unit, adapted for alternative manual operation and primarily for use on aircraft, the motor drive is through an epicyclic gear controlled by a reaction brake which is released when the manual driving means is engaged so that the manual drive does not turn the motor. The shaft 2 of the motor 1 drives the output shaft 9 through an epicyclic gear comprising a sunwheel 6 on the shaft 2, an internally-toothed annulus 10 and interposed planet-wheels 7 on a carrier 8 secured to the shaft 9. The annulus 10 is mounted to rotate in a fixed housing 11, and a flange on it is pressed into braking engagement with the housing by a spring- loaded ring 12. This maintains the annulus stationary whilst the motor drives the shaft 9 through the sun-wheel 6 and planet-wheels 7, though slip would occur in the event of an overload. The manual drive of the output shaft 9 is through bevel gears 14; 15 from a shaft 16 terminating in a clutch 17 for engagement with a complementary element 19 on a handle 18. When the handle is applied to the jack, a flange 20 on it rocks a lever 21 and this releases the ring 12 from the annulus 10 which is then free to rotate in the housing 11. The handle 18 therefore drives the shaft 9 without effect on the motor 1 which is held by a normally applied, electrically-released brake 4.

Title: Thread cutting and nipping mechanisms for sewing machines
IPC: D05B65/00
Filed: 1919-02-07
Abstract: 142,561. Fairweather, W., (Singer Manufacturing Co.). Feb. 7, 1919. Button-hole sewing-machines; thread-cutters and end-holders.-In a buttonhole sewing-machine in which the needle thread s cut and held at the completion of a button-hole and is released after the commencement of the next stitching operation, the thread-nipper is operated to release the needle-thread end by connexion with the main shaft of the stitching- elements. The thread-cutter and end-holder comprises two arms 41, 42, Fig. 7, pivoted at 40 on an extension of the workclamping foot 22'. The lower arm 42, in conjunction with a fixed blade, cuts the thread, and the upper arm 41 nips the thread against the underside of an upper plate. The arms 41, 42 are operated together by means of a rod 49, Fig. @. The rod is urged rearwardly for the cutting and nipping operation by a spring 52 and is restrained by a latch 57, which is withdrawn by the feed-cam, acting through a lever 74 at the close of a cycle of operations and just prior to the opening of the work-clamp by means of the same lever 74 and a plate 63. During the first revolution of the main shaft 5, Fig. 1, of the stitching- devices, a switch cam 90 operates upon a lever 88, Fig. 1, and a lever 86, Fig. 4, is swung to the right and the rod 49 actuated to retract the thread-nipper and release the thread. After the lateral movement of the lever 88, the spring-pressed pin 89, engaging the groove in the cam, is, pressed outwards by a rise in the cam-surface and is latched in its extreme position out of contact with the cam by a latch 96. The lever 88 being freed, a spring 94 returns it to its original position and removes the lever 86; the rod 49, however, remains locked by the latch 57 until the completion of the button-hole stitching. After the completion of the stitching, the stitching-elements are, by the bar 14 and the usual toothed gears, turned back to initial position, and, in this movement, a tooth 103 on the bar 14 engages with a latch tooth 100, Fig. 4, past which it had previously snapped, and moves the latch 96 from engagement with the pin 89. The pin thereupon moves into the groove of the cam 90 and is available for the operation of the lever 88 on the first revolution. The needlethread passes a tensioning-device 125, a rotary take-up 127, and down the centre of the hollow needle-bar. A thread pull-off 130 is operated prior to the commencement of stitching, by means of a lever 135 and a pin 140 on the cutter-lever 8.
