Title: Improvements in the manufacture of tin-plated lead collapsible tubes
IPC: B21C23/22
Filed: 1942-03-11
Abstract: 553,819. Making cased collapsable tubes. BELTS & CO., Ltd., and DUNN, E. STATHER-. March 11, 1942, No. 3199. [Classes 83 (ii) and 83 (iv)] A collapsable tube is made by separately rolling, or otherwise making, three layers of tin, lead, and tin, punching compound discs from the superposed layers and then extruding. The scrap is easily separated into its constituents for re-use. The inner and outer tin layers, and, if desired, the lead may be alloyed with other metals to ensure the same rate of extrusion and improve ductility, rigidity, &c. To reduce the unplated end-portion, the discs 1 may be cut slightly larger than the extrusion-die cavity 3 and be placed in an additional recess 2 in the die of the same diameter as the discs. The punch 6 then produces a plated extruded tube with a thick and partly plated end ring, which is cut off.

Title: Method and apparatus for enabling liquid slags to solidify in a highly porous condition
IPC: C21B3/06
Filed: 1937-02-04
Abstract: 469,377. Treating slag. BUDERUS- 'SCHE EISENWERKE. Feb. 4, 1937, No. 3361. Convention date, Feb. 5, 1936. [Class 22] Liquid slag is deposited on the surface of a rotating body or wheel and caused to solidify in a porous condition by supplying water or steam from the interior to the surface of the body or wheel through devices not taking part in the rotation. As shown, liquid slag drops from a channel 11 into the trough-shaped rim of a rotating wheel 1, and water or steam is forced from a conduit 7 through apertures 6 constituting a grate extending around the wheel. Excess water is caught in a trough 8 and overflows to a channel 10. A retaining plate fitted in the trough-shaped wheel rim prevents slag and water flowing backwards against the rotation of the wheel, and interior curved plates are provided under the apertured zone in front of and behind the spraying nozzles and trough 8. The rim of the wheel may be cylindrical instead of trough shaped. One wheel may have several apertured zones, the slag being supplied to the intervening non-apertured surface which may be convex in form. The slag deposited on the wheel, may also be subjected to the action of water, steam, or gas directed from above, e.g. so as to bank it up on the wheel.

Title: Improvements in processes and apparatus for the production and consolidation of metals and alloys
IPC: C22C33/02
Filed: 1941-03-12
Abstract: 557,868. Extracting iron and other metals; alloys; metal forging; moulding. STEVENS, A. H. (Minerals & Metals Corporation). March 12, 1941, No. 3377. [Classes 72 and 82 (i)] [Also in Groups V and XXII] In the reduction of ores for the production of metals or alloys, finely concentrated ore is reduced directly at a temperature below both the melting and sintering temperatures of the metal to be produced and the metallic powder produced is compressed in a protective atmosphere into a self-sintering mass while the powder is still hot from the reducing operation. The gangue may be separated, e.g. by magnetic concentration, from the metal between the reducing and compressing steps in a non-oxidizing atmosphere and carbon or powdered alloying metals added to the metal powder at this stage and after the separation. Alternatively in the production of iron alloys.oxides of the alloying metals may be added to the iron ores before reduction . The ore 8, free from gangue, is fed on to the hearth 10 of the reducing chamber 2 of the furnace 4 and flows therealong, being acted upon by reducing gases which pass obliquely through the ore bed through orifices 12 to which they are fed by conduits 14. A predetermined minimum depth of ore is maintained. on the hearth by a dam 15 over which the reduced ore flows into a shoot 16 connected to the furnace. The metal particles 24 fall between briquetting rolls 18, 20 enclosed in a casing 26 and provided with half-moulds 22, Fig. 2, and the consolidated metal 27 falls on to a conveyer 28 contained within a casing 30 and is passed either to an electric or open hearth furnace, where, if iron ore is treated, the iron is converted into steel or to a storage' bin for further treatment. In a modification, Fig. 4, the reduced metal falling down the shoot 16 is cooled down by blasts of reducing gas introduced through lower perforations 42 and perforations 44 in the side of the shoot 16, the gas streams from the latter perforations being inclined as shown. To assist in the separation of any gangue which may still be sticking to the metal, magnets 40 on the shoot 16 cause the metal to move towards the wall on which the magnets are and the metal then falls down the shoot 16, the freed gangue passing away by a shoot 36. The metal is converted into a sheet by rollers 46, 48 which is further compressed by the 4-roll arrangement 50, 52, 54, 56, the sheet then passing over rollers 60, the whole being enclosed in a casing 58. The compacted metal may be extruded through a die or may be introduced into a heated container and both the latter and its contents extruded through a die.

Filed: 1919-02-14
Abstract: 160,472. Anninger, M. Feb. 14, 1919. Gas, supplying by meter.-A prepayment meter comprises a pair of screwed shafts each having thereon a nut and so arranged that both nuts must be in their zero position in order that the supply may be cut off. The meter shaft 1 drives through worm gearing a shaft 3 carrying a pinion 4 which engages pinions 5, 6 loose on shafts 7, 8. Sleeves 9, 10 connected to the shafts by pins and slots carry pinions 21, 22 which may be slid into engagement with projections 23, 24 on the pinions 5, 6 so as to rotabe therewith. Nuts 13, 14 are mounted on the screwed parts of the shafts 7. 8 and carry pointers 15, 16 which move over graduated scales, and fingers 17, 18 which engage collars 19, 20 on the sleeves 9, 10, as the nuts respectively approach their zero position, and disengage the pinions 21, 22. The collars 19, 20 also engage bell-crank levers 29, 30 connected respectively by links 33, 34 to levers 31, 32 controlled by springs 35, 36 and having notches adapted to engage the ends of the levers 30, 29 respectively. The levers and collars are so arranged that when one of the wheels 21, 22 is clutched to the pinion 5 or 6 the other is disengaged. The particular wheel that takes the drive from the wheel 4, and therefore the nut 13 or 14 that is driven, is determined by the actuation of a setting-rod 46 or 47 by a key applied to the end of one of the shafts 7, 8 to set the nut back. The ends of these rods engage the collars 19, 20 and the rod last actuated disengages the wheel with which it is associated and engages the other wheel. As one of the nuts, for example 13, reaches the end of its travel the finger 17 thereon engages the collar 19 and disengages the wheel 21, and at the same time the collar acting through the bell-crank levers and catch-levers engages the wheel 22 and starts the shaft 8. A floating lever 39 connected by links &c. to the valve 44 is adapted to be engaged by the nuts 13, 14 but will only be moved bodily to actuate the valve and shut off the gas when both nuts reach their limiting positions.

Title: Improvements in or relating to the moulding, shaping and working of dough
IPC: A21C7/00
Filed: 1922-02-08
Abstract: 193,261. Greenwood, E., and Sharp, A. Feb. 8, 1922. Dough-working machines.-In dough working machines of the kind described in Specification 108,699, a clot of dough is rotated in contact with an exterior moulding surface about an axis initially defined by a spindle embedded in the dough, and the spindle is caused to travel relatively to the dough in a direction towards and away from the exterior moulding surface. Two coaxial spindles 7, 8 rotated in the same directions at different speeds from the shaft 5, receive axial movement which causes them to approach and recede from one another by means of cams 11, 12 keyed to a shaft 13 driven from the main shaft 3. The moulding surface comprises two series of rollers rctatably mounted on spindles carried by levers 20 adjustably mounted at 21 on a rocking shaft 22 carried in bearings by the gear box 2. Rocking motion is communicated to the moulding surface by means of cams 23, 24, keyed to the shaft 13, either of which can be brought into engagement with a roll 26 carried by a spring-controlled arm 25 keyed to the shaft 22. Clots of dough are fed to the moulding surface by a conveyer band 29 mounted between an idle roller 30 and a roller 31, the latter being keyed to an intermittently rotated shaft 32 driven from the cam shaft 13 by means of chain gearing. The differential speed of rotation of the spindle stretches and works the dough and the moulding surface 18 shapes it into cylindrical form. As the moulding surface is caused to approach the spindles by means of the cams 23, 24 the spindles 7, 8 are caused to travel relatively to the dough towards the circumference thereof, and similarly when the moulding surface recedes from the spindles the latter will travel relatively towards the centra of the dough. At the completion of each moulding operation the dough is removed from the moulding surface by arms 43 on the cam shaft 13, the said arms having projections 44 adapted to pass between the rollers. In a modification, the moulding surface and its movement towards and away from the spindles are provided by eccentrics rotated at the desired speed and carrying sleeves or, the like rotatable thereon by contact with the rotating lump of dough. In another modification, the differentially rotated spindles may be replaced by a spindle or spindles used mainly to define the normal axis of rotation of the dough and to form one boundary of the gap in which working takes place, the actual rotation of the dough being effected by means such as crank pins or by an endless belt driven around rollers movable with the moulding surface.

Abstract: 1, 071, 371. Gyroscopic apparatus. BODENSEEWERK PERKIN-ELMER & CO. G.m.b.H. Jan. 28, 1965 [Feb. 8, 1964], No. 3829/65. Heading G1C. A stabilized platform 50 having three stabilizing gyros 78, 80, 82 is mounted in three gimbals, an inner roll gimbal 52, a pitch gimbal 56 and an outer roll gimbal 60 to prevent gimbal lock, the inner roll gimbal 52 and pitch gimbal 56 being maintained perpendicular to each other by means of an angle pick-up 80 controlling a follow-up motor 74, a micro-switch (not shown) being provided on the outer roll gimbal 60 to be actuated whenever the angle between this gimbal 60 and the pitch gimbal 56 approaches a right angle, the micro-switch controlling the motor 74 to give prompt turnover of the outer roll gimbal 60 and prevent precession and other disturbing effects when the aircraft in which the platform is mounted carries out a vertical or near-vertical climb or dive. The spin axes of the gyros 78, 80 are arranged parallel to the axis 54 of the platform with their input and precession axes mutually at right angles to each other. The spin axis of the gyro 82 is horizontal and radial with respect to the axis 54. Slave torque motors 68, 70, 72 are controlled by the gyros to stabilize the attitude of the platform 50 in space. If the aircraft in which the platform 50 is mounted flies a very accurate loop path the gimbal turnover of the outer roll gimbal will take place very rapidly in order to preserve the required gimbal attitude relationships, thus causing disturbing torques to affect the platform. The action of the microswitch referred to prevents this by starting the gimbal turnover before the vertical climb attitude is reached. An electrical circuit to effect this is described in the Specification also a means of preventing continued action of the motor 74 by the micro-switch, if the aircraft leaves its loop path in the vertical climb attitude to follow a path along an angle of sideslip.
