Title: Improvements in or relating to slide fasteners
IPC: A44B19/60
Filed: 1948-10-26
Abstract: 655,337. Sliding clasp fasteners. TALON, Inc. Oct. 26, 1948, No. 27799. Convention date, Oct. 31, 1947. [Class 44] [Also in Group XXII] A machine for making and applying stop members to releasable fasteners comprises means for feeding a continuous length of wire to shearing and bending tools which form the stop member and transfer means for moving the stop member to a station where it is attached to a stringer tape. The machine is driven by an electromotor through a one revolution clutch 15 actuated by a pedal rod 24 and rotating a shaft 10. The latter is geared to a shaft 7 carrying cams 37 actuating the shearing and bending mechanism, a Geneva stop mechanism 72 rotating a blank carrier 63 and a shaft 53 of a feed roll 51. The wire feed mechanism comprises a roller 51 on the driven shaft 53 co-operating with an idle roll 52 on a lever 58 urged by a spring 60. Shearing. The wire W is fed through a guide 50 into a die block 61 and is severed by an edge 34a of a punch 34 reciprocated by cams 37. Bending. Within the cutting punch 34 a bending punch 38 is reciprocated by grooves in the cam 37. It co-operates with a die 42 slidable in the block 61 against spring pressure. Blanks transferring. The blank carrier 63 is rotated by a geneva stop mechanism and comprises jaws 75 pulled by springs 78 against stops 101 and guided on a plate of the carrier 63. The jaws are closed by the end 89 of a plunger 88 actuated from the cam 37. Operation. The wire is fed into the die block 61 and sheared by the punch 34. When the one revolution clutch is operated, the punch advances and pushes the blank into grooves 45 in the bending die 42 and pushes the bending die against the urge of springs 86 flush with a surface 87 on the carrier. The bending punch 38 then forces the blank through an aperture in the die 42 to convert it to U-shape, Fig. 7, not shown, and to position it between jaws 75 in the carrier. The carrier is then rotated by the geneva stop mechanism to bring the jaws to the attaching station where the stringer tape is inserted by hand into the projecting legs of the stop. On operation of the plunger 88 the part 89 moves the jaws 75 outwards and wedge surfaces, 76, 77, Fig. 13 (not shown), close the jaws to clamp the stop on the tape. The tape is removed and the parts restored at the end of the cycle.

Title: An improved process for providing a resistant coating upon the surfaces of aluminiumor aluminium alloys
IPC: C25D11/08
Filed: 1927-10-20
Abstract: 290,901. Gower, C. R. R., and O'Brien & Partners, Ltd., S. Oct. 20, 1927. Aluminium compounds, obtaining. - A resistance coating is produced on the surface of aluminium or an aluminium alloy by anodic treatment in a bath containing a substantial proportion of sulphuric acid or of a substance giving rise to sulphuric acid at the anode. Bichromate of potash, hyposulphite of soda, acetate of lead, barium sulphite, or sulphocyanide of ammonia or of potash or mixtures thereof may be added to the bath to colour the coating. Ammonia or an ammonium salt may be added to darken the colour. The bath may contain 1¢-2 lbs. sulphuric acid per gallon of water, or may contain 10 per cent by volume of acid. The bath should be cold on starting but not below 60‹ F. The treatment may last from 25 to 70 minutes. The object may be first cleaned with an abrasive powder, then immersed in a boiling solution of brown potash and washed in cold or hot water. It is then connected as anode and put into the electrolyte bath with the current on. The object is suspended by a short thick wire of copper or of a metal not attacked by the bath. A large object may first be partially immersed and then reversed to treat the remainder. A voltage of 6 is employed, the current density being initially 10 amps. per sq. ft. to a steady falling value of 2 amps. per sq. ft. The object may be treated successively in different baths. To obtain a thick coating, the object is treated repeatedly in the same bath, being dried and exposed to the air or oxygen between successive treatments. Detailed directions for the preparation of baths to produce coatings of particular colours are given. A final anodic treatment in a bath containing sulphuric and nitric acids may be employed to give the coating a hard white or silvery appearance.

Title: An improved process for eliminating sulphur compounds from gases
IPC: C10K1/34
Filed: 1927-10-20
Abstract: 310,063. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Oct. 20, 1927. Purifying processes; materials and compositions for purifying. - Sulphur compounds are removed from coal gas, water gas, or producer gas, by passing the gas with sufficient oxygen or oxygen-containing gas to form sulphur-oxygen compounds, over solid adsorbents, particularly active charcoal or bodies containing it, at 150-250‹ C., or over compounds of alkaline earth metals, aluminium, or heavy metals with non-metals other than oxygen of the 5th and 6th groups of the periodic system. Ammonia is added if necessary before or after the catalytic treatment to ensure the formation of ammonium salts, or the sulphur-oxygen compounds are washed out with aqueous ammonia. Nitrides, phosphides and sulphides of copper and the iron group of metals are suitable agents, the temperature required being up to 400‹ C. In a modification, the adsorbent charcoal is first charged with sulphur in known manner by limiting the oxygen supply, the sulphur then being oxidized by supplying air or oxygen at 150-250‹ C. The hot gases coming from the catalyst may be cooled only to the degree in which sufficient water vapour for the formation of ammonium salts, particularly sulphite, is present, gaseous ammonia then being added and the salts precipitated as in an electrical separator. In an example producer gas containing 2.7 grams of sulphur per cubic metre is mixed with 2 per cent by volume of air and passed over a granular catalytic alloy, consisting of 67 per cent of iron, 22 per cent of phosphorus and 11 per cent of silicon, heated to 400‹ C., 0.4 per cent by volume of gaseous ammonia is mixed with the escaping gases at 350‹ C., the ammonium salts being separated as by means of a high tension electric field. Specification 280,947 is referred to.

Abstract: 431,763. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Foulke, T. E. ; 30, Evelyn Place, Nutley, New Jersey, U.S.A.) Oct. 10, 1933, No. 27923. Void [Abridged as open to inspection under Sect. 91 of the Acts, April 12, 1934]. [Class 39 (i)] In a gas discharge device for use as a relay, sputtering of cathode material on the envelope is prevented by means of a shield or by forming the electrodes to act as shields. As shown, a shielding disc 7 of mica or glass is secured to the anode 6 by wires 8, and a smaller mica disc 9 spaces the anode from the envelope. A cathode 4 and an anode 5 for producing a starting discharge are of semicircular shape, and are mounted on leads 2, 3. The distance between the electrodes 4, 6 is greater than the distance between either electrode and the envelope. The back of the electrodes 4, 5 is coated with aluminium powder as described in Specification 397,107 so as to confine the glow to the front of the electrodes. The electrode 4 is coated with alkaline or alkaline earth metal by spraying a mixture of barium or strontium carbonates or nitrates mixed with a binder such as nitrocellulose and cellulose acetate. The envelope is evacuated and heated to 450‹ C. to drive off occluded gas. The electrodes are heated to 1300‹ C. by a highfrequency magnetic field to reduce the carbonates &c. to oxide and the binder to carbon. A filling of neon with one half per cent of argon at a pressure of 50 mms. is introduced and a high-frequency discharge with a steep wave front is passed between the electrodes 4, 5 so as to break up a part of the barium oxide, leaving barium cemented by oxygen and barium oxide. Any oxygen evolved is cleaned up by the aluminium coating. For use with alternating current the electrode 5 is similarly coated. The electrodes 4, 5 are connected with the secondary of a transformer 16 through a battery 15 and a resistance 17. A resistance 20 and contacts 21, normally open but arranged to be closed by a magnet 19, are connected between the anode 4 and the output which includes a battery 18. The auxiliary discharge between the electrodes 4, 5 starts a discharge between the anode 6 and cathode 4, the discharge being broken by the insertion of the resistance 20 through the contacts 21. In a modification, Fig. 2, (not shown), the electrode 5 is omitted and the anode 6 consists of a nickel or iron disc ; the magnet 19, contacts 21, the transformer secondary, and the load battery 18 are connected in series between the two electrodes.

Filed: 1922-10-23
Abstract: 211,535. Simon, W. G., and Simon, F. R. Oct. 23, 1922. Automatic-feed weighers are provided with extracting means controlled by or through the weigh-beam, such means being adapted to extract a portion of the material being weighed when the weigh-beam has descended owing to an overweight. The extracting means may comprise a suction pump, fan, screw or other device actuated by any desired power. As shown, a sack 3 carried by a weigh-beam 8 is adapted to be filled from a hopper 7 until the weigh-beam descends when the supply is cut off in known manner. As the weigh-beam descends it closes a switch 10 controlling an electric motor 5, thus causing a pump 4 connected to the motor to extract material from the sack through a pipe 1 until the weigh-beam is in equilibrium when the switch is opened and the suction ceases. The material extracted from the sack is returned to the hopper 7 through a pipe 6. In a modification, the motor 5 runs continuously and the weigh-beam operates a valve 11 in the suction pipe 1.
