Abstract: An oxidation catalyst (Example III) consists of a mixture containing 80% wt. phosphomolybdic acid, 6,2% wt. bismuth oxide, 3,8% wt. molybdenum oxide and 9,5% wt. silica.  Reference has been directed by the Comptroller to Specifications 878,802, 893,077 and 903,034.ALSO:Unsaturated monocarboxylic acids are prepared from olefines by a process characterized in that firstly the olefine is oxidised in a first reaction zone by means of molecular oxygen to an unsaturated monoaldehyde under the influence of a heavy metal compound as first oxidation catalyst and at a temperature in the range 250-650 DEG C.; and the monoaldehyde so obtained is then oxidised by means of molecular oxygen in a second reaction zone to the corresponding monocarboxylic acid at a temperature in the range 350-575 DEG C. and under the influence of a second oxidation catalyst which is an oxygen-containing compound of a heavy metal of Group VI of the Periodic Table (chromium, molybdenum, tungsten and uranium); the first and second reaction zones being separate and employing separate catalyst beds and the total effluent of the first zone being passed on to the second zone without purification.  The reactions are preferably conducted in the presence of water vapour.  Further oxygen and water may be added to the effluent from the first zone before feeding to the second zone.  The contact time in the second zone preferably does not exceed 0,75 second.  The catalysts may be used as such or with a carrier or diluent. The catalyst beds may be in the same or different reactor vessels and may be fixed or fluidised. Gases may be recycled to either zone after product recovery. Pressures in the first zone are preferably higher than in the second. The process may be used for the oxidation of propylene and isobutylene to acrylic and methacrylic acids respectively. The starting materials may be diluted with paraffins.  Specifications 821,999, 822,140 and 839,808 are referred to.  Reference has been directed by the Comptroller to Specifications 878,802, 893,077 and 903,034.

IPC: B23K9/173
Filed: 1958-08-12
Abstract: 880,568. Welding by fusion. KAISER ALUMINIUM & CHEMICAL CORPORATION. Aug. 12, 1958 [Aug. 16, 1957], No. 25913/58. Class 83 (4). In a gas-shielded metal arc-welding process, two concentric layers of shielding gas are used, the inner layer being an inert monatomic gas and the outer layer being any suitable shielding gas. When both layers are of inert monatomic gas the inner layer contains a halogen or halogen containing substance in solid liquid or gaseous form, as described in Specification 801,039. For example, chlorine may be added to the inner layer in quantity from 0.01 to 2% of the total shielding gas. The inert monatomic gas is argon, helium or a mixture thereof, e.g. 75% helium, 25% argon. Other shielding gases specified for the outer layer are carbon dioxide and nitrogen. The workpiece and electrode may be copper or aluminium or alloys thereof such as aluminium alloys containing 4.5% Mg and 0.75% Mn, or 1% Mg, 0.6% Si, 0.25% Cu and 0.25% Cr, or 5% Si. As shown in Fig. 3, the welding process produces a depression in the weld metal and the tip of the electrode is maintained in the plane of the rim of the depression. The inner layer may be fed through the contact tube or may be introduced on the exit side of the contact tube. A welding gun for carrying out the process has an inlet pipe 9, Fig. 1, for the outer layer communicating with the gas nozzle 5 and an inlet pipe 14 for the inner layer connected by a coupling piece 10 to the contact tube 17. A seal 29 prevents escape of shielding gas along the flexible tube 27 through which the electrode 11 is fed. Reference has been directed by the Comptroller to Specification 811,435.

Title: Improvements in or relating to safety control and ignition systems for gaseous fuel burners
IPC: F23N5/10
Filed: 1945-10-05
Abstract: 601,739. Gas burners. ELLIS, L. S. E. (Robertshaw Thermostat Co.). Oct. 5. 1945, No. 25998. [Classes 75(i) and 75(iii)] f Also in Group XXIX] In a safety control system for a main gas burner 10 and pilot burner 44 the closing of a main switch 78 completes the circuit through an initially closed switch 84 to the primary coil 64 of a transformer 60 and thereby energises a pilot burner igniting coil 69 and operates electromagnetically a plunger 62 to raise the stem 31 of a valve 16 against the resistance of springs 26, 34. In the raised position a member 50 on the stem prevents gas from passing to the burner 10 but gas can pass through a conduit 46 from the valve opening 20 to the pilot burner 44. In addition a collar 41 on the stem raises an armature 38 into contact with the pole faces of an electromagnet 36 and completes at contacts 94, 96 a circuit to a heating coil 88 around a bimetallic operator 86 for the contacts 80, 82 of the switch 84. If the pilot burner has been ignited a thermocouple 52 adjacent its flame supplies current to the electromagnet 36 to hold the armature in position with the contacts 94, 96 closed before the operator 86 separates the contacts 80, 82. When this separation occurs the transformer circuit is broken and the stem 31 drops until a collar 40 spaced above the collar 41 engages the armature 38 in which position gas passes to the main burner 10. If flame failure occurs the armature 38 drops and the valve 16 closes, recycling occurring after the operator 86 has cooled. The main switch 78 may be manually or thermostatically operated either independently or in conjunction with a main gas valve 14.
