Filed: 1968-07-16
Abstract: 1,166,427. Ultrasonic testing of bonds. FORD MOTOR CO. Ltd. 16 July, 1968, No. 33759/68. Heading H4D. A bond between a metal member and a rubber body is tested by applying a stress tending to separate the body and member, applying ultrasonic vibrations to the member, and determining the amplitude of echoes from the metal/ rubber interface, bond flaws benig indicated by abnormally high amplitude echoes. In the embodiment shown, for testing an engine mounting comprising a rubber bush 13 and metal flanges 11, 12, stress is applied to the mounting by an hydraulic piston and cylinder arrangement. Probe 22 comprising transmitting and receiving transducers is coupled to flange 11 by a liquid film and is scanned over flange 11. If many similar mountings are to be tested, single-shot multivibrators 27, 29 open gate 26 for a fixed period embracing the arrival time of echoes from the interface between flange 11 and bush 13, and these echoes are passed to amplitude discriminator 31 which actuates a lamp or bell if the echo amplitude is excessive. If different mountings are to be tested the echoes are observed on an oscilloscope triggered by the pulse transmission.

Title: Switching circuits for controlling current flow in a load
Inventor: WRIGHT MAURICE JAMES
IPC: H03K17/73
Filed: 1961-09-21
Abstract: 1,031,460. Semi-conductor controlled rectifier oscillator; switching circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. Sept. 3, 1962 [Sept. 21, 1961], No. 33799/61. Heading H3T. [Also in Division G1A] In a switching circuit comprising a semi-conductor controlled rectifier, a free running oscillator, including a capacitor which is alternately charged and discharged, is arranged so that the discharge current of the capacitor switches off the controlled rectifier if the latter is conducting, and variable resistance means are provided for determining whether or not the controlled rectifier is switched on during the charging of the capacitor. Capacitor 9 charges through resistor 10 and the gate and cathode of the controlled rectifier 6 until the voltage across it is sufficient to cause four-layer diode 11 to break down when the capacitor discharges through diode 11 and the rectifier 6 to switch the latter off if it is conducting. The cycle is then repeated. Since the charging current alone is insufficient to switch the rectifier 6 on the latter will only be switched on provided the resistance of photo-sensitive resistance device 8 is above a predetermined value, i.e. a predetermined part of the current flowing through resistor 7 flows through the gate and cathode of the rectifier 6. In the arrangement of Fig. 2 (not shown), the resistor 7 is omitted and the photo-sensitive device is connected between the gate and the terminal 3.

Title: Method of catalytically inducing oxidation of carbonaceous materials by the use of molten salts
IPC: B01J35/12
Filed: 1971-07-21
Abstract: 1350700 Reduction of air pollution ANTIPOLLUTION SYSTEMS Inc 21 July 1971 [23 July 1970] 34104/71 Headings C5G G10A and G 11 [Also in Divisions F1 and F4] Carbonaceous materials containing hydrocarbons and/or carbon monoxide are brought into contact with a molten salt in the presence of oxygen in order to catalyze the oxidation of said material. Many molten salt mixtures are specified, mainly based on halides. Eutectics are especially useful, and it is preferred that the molten salt bath should be at a temperature approximately 93C above the melting point of the mixture. In general the salt or salt mixture may have a melting point between 50C and 600C. The carbonaceous material may be a liquid or solid fuel, e.g. wood or coal, a plastics material, propane, kerosene, crude oil, natural gas or an automotive exhaust gas. Solid materials may be directly combusted by being added to the baths, any carbon monoxide or hydrocarbon evolved being oxidized in a further bath. In the case of a gas or vapour, the material to be oxidized may be passed over the surface of the molten bath. An oxidizing agent may be present in the bath to give off nascent oxygen and take up ambient oxygen from the mixture of carbonaceous material and air being passed into the bath, thus maintaining a partial decomposition pressure of oxygen above the molten salt. The oxygen may be introduced electrolytically, e.g. by using a nitrate bath, the nitrate anions giving rise to oxygen at the positive electrode. When the carbonaceous material is an automotive exhaust gas, a nitrate oxidizing bath is preferably used at about 365C. The carbonaceous material may also contain sulphur dioxide, nitrogen oxides, chlorine, cyanides, and/or phosphorus compounds which may be removed by adding to the bath getters such as CaO, Na 2 O, MgO, MnO, ZnO, CaO or BaO. Carbon dioxide produced by oxidation of carbon monoxide may be removed by addition of calcium oxide to the bath.

Abstract: 605,168. Welding. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 17, 1945, No. 34111. Convention date, Aug. 15, 1944. [Class 83 (iv)] [Also in Group XXXV] In order to forge the weld, a fluid-pressure system associated with the welding-electrodes for clamping a workpiece therebetween is caused to effect an additional pressure on the electrodes at a predetermined time during the welding-operation, notwithstanding the time lag in. the mechanism. The invention is described as applied to a capacitor discharge welder of the type disclosed in Specification 585,437, [Group XXXV]. Valves 97, 98 in cylinder 99 operate in response to the closure of switch 203 to close respectively the air line 76 to the exhaust port 78 and apply air pressure from source 79 through this air line to piston 74 associated with movable electrode 15 which then closes on to workpiece 19 between it and fixed electrode 17 against a lower air pressure from source 105 controlled by valve 101 in cylinder 103. Back pressure in air line 76 acts upon piston 83 of pressure switch 80 to open contactors 81, 82 to effect, respectively, the opening of a flux resetting circuit for the transformer 11 and the conduction of an electric discharge device 179, which latter controls through capacitors 133 and 161 the conduction of electric control valves 109 and 151 to respectively initiate the flow of welding current through the primary 9 of the welding-transformer 11 and 'the subsequent energization of solenoid 100, which closes its valve 101 to interrupt the air supply from source 106 and open valve 102 to exhaust port 107, thus effecting increased pressure above the piston 74. This pressure is maintained until switch 203 is opened.
