Patent GB-955682-A (GB)
Title: Production of aromatic sulfonyl chlorides
IPC: C07C309/80
Filed: 1960-08-15
Abstract: Aromatic sulphonyl chlorides are prepared by sulphonating an aromatic compound with chlorosulphonic acid and quenching the reaction mixture after sulphonation with a mixture of an inert, water-immiscible organic solvent having a boiling point not greater than 110 DEG C. and water, separating the organic layer containing the sulphonyl chloride and recovering the sulphonyl chloride from the solvent.  The organic solvent is preferably a hydrocarbon or halogenated hydrocarbon.  In a modification of the process the reaction mixture may be diluted with the organic solvent and this mixture added to water. Examples describe the preparation of acetyl-sulphanilyl chloride using methylene dichloride and water for quenching and chlorobenzene-sulphonyl chloride using hexane and water for quenching.

Abstract: 1,255,668. Bearings. LIPS N.V. 4 June, 1969 [5 June, 1968], No. 28353/69. Heading F2A. An apparatus for transferring a liquid under pressure from a member (not shown) to a passage in a shaft or vice versa, the member and the shaft being relatively rotatable, comprises a bearing. -In an embodiment a bearing 4, Fig. 1, having linings 5 and a radial passage 8, has a shaft 1, having a radial passage 3, mounted therein. The radial passages 8 and 3 are connected together by means of an annular passage 7 in the bearing 4. The latter is also-provided with an annular passage 12 which connects with a radial passage 11 formed in a ring 9. In use pressurized fluid is supplied from the member (not shown), through the radial passage 11 in the ring 9 and is conveyed by means of the passages 12, 8 and 7 in the bearing 4 to the radial passage 3 in the shaft 1. The radial passage 3 passes pressurized fluid to a control device of a controllable pitch propeller (not shown), via an axial passage 2. Some of the pressurized fluid passes between the bearing and the shaft and discharges through outlets 13, 14. The pressurized fluid in the annular passage 12 compensates for the outwardly directed forces due to the pressurized fluid passing between the bearing and the shaft. In modifications the ring 9 is omitted and the passages 12 and 8 are replaced by a chamber 15, Fig. 2 (not shown), and a ring 16, Fig. 3 (not shown), is provided with linings 5 which engage the shaft 1.

Title: Method of treating exhaust gases containing sulphur dioxide
IPC: C01C1/242

Abstract: Sulphur dioxide is removed from exhaust gas by catalytic oxidation to sulphur trioxide, using a vanadium pentoxide catalyst at 340-410 DEG C. and at a space velocity of 1000-8000, followed by reaction of the sulphur trioxide with water vapour and gaseous ammonia at 60-25 DEG C. to form ammonium sulphate crystals.  After the catalytic oxidation the gas is cooled, either before or after the addition of gaseous ammonia (and steam if required), to a temperature at which ammonium sulphate crystals condense from the gas (below 250 DEG  C.) but is maintained above the decomposition temperature of ammonium sulphite.

Abstract: 393,832. Turning bags inside out. MILLIE PATENT HOLDING CO., Inc., 288, Southern Boulevard, New York, U.S.A. Oct. 17, 1932, No. 28941. Convention date, June 18. [Class 112.] Fabric bags, for tea, coffee, &c. are transferred from a bag-making or supply station to a station at which the bag is simultaneously filled and turned inside out. The bags 23, Fig. 4, arrive from the previous station on arms 22 on an intermittently rotating wheel 20 and are pierced by four needles 25, 26 mounted on a head 29 mounted to slide on guides 30 on a frame 31, Fig. 1, pivoted on a journal 32 and then in its lower horizontal position. After the bag has been engaged by the needles, the arms 22 are caused to approach each other, and to free the bag, by the action of an arm 33 on an extension 34 of one of the arms 22. The arms are intergeared and are normally urged apart by a spring 24. At about the same moment the stitching between the bags is severed as indicated in Fig. 3. The needles are moved relatively to each other to open the bag into the square formation shown in Fig. 8, the bag is withdrawn from the arms 22 by a sliding movement of the head 29 upon the frame 31, and the frame is moved into the vertical position shown in Fig. 1 ; the bag is now held mouth downwards over a supporting device 74 comprising relatively movable fingers 74<1>, 74<11>, Fig. 13. The frame descends to lower the bag into position, and pressing members on an arm 94 clamp the bag against the fingers when the frame withdraws. The fingers are mounted on an intermittently rotating table 75, and are opened by springs 85 on guide rods 86, the action being controlled by a fixed cam 84 an rollers 83 on the arms carrying the fingers 74<11>. A partial rotation of the table brings a bag beneath a vertically reciprocable spout 114, Fig. 15, which descends and turns the bag inside out. At the same time a charge of material passes down the spout into the bag, which is delivered on to a table 115, and removed therefrom in any convenient fashion.

Title: Improvements in and relating to electric control circuits
IPC: B23K11/24
Filed: 1945-11-02
Abstract: 627,831. Automatic control systems for welding circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 2, 1945, No. 29154. Convention date, Nov. 7, 1944. [Class 38 (iv)] Voltage, current, control.-Timed applications of A.C. are transmitted from the supply 11 to a load circuit 10 through electronic valves 12, 13, grid controlled by the output of a phase-shifting circuit 24 which also controls an electronic rectifier 30, 31 continuously energizing a resistor 29 with D.C. from the A.C. supply. Variations in the average voltage across the resistor 29 control the phase-shifting circuit to maintain the resistor voltage constant and to render the R.M.S. load current in 10 independent of supply voltage variations. Welding transformer 10 is energized from the A.C. supply 11 through the reversely-parallel connected gas-filled valves 12, 13, the grids of which are supplied with voltages in and out of phase with the anode-cathode voltage, from transformers 17 and 18, the in-phase voltage being controlled by a timer which determines the number of cycles of load energization. A peaked waveform from the saturable transformer 21 is also supplied to the grids, and its phase determines the duration of load energization in each cycle. A second saturable transformer 32 supplies a peaked waveform to the grids of rectifier valves 30, 31, the anodes of which are supplied with A.C. by transformer 34, energized from tappings on the primary of transformer 35 which also supplies valveheater currents, and energizes the time delay relay 37, which delays the application of voltage to the anodes of valves 22. 23, 30, 31, until the heaters are fully operative. The rectifiers energize' a load resistance 29 continuously, the voltage across which is averaged by capacitor 61, and a portion is tapped off by the potentiometer 60 to be amplified by valves 27, 28, the D.C. anode and grid voltage being derived from the resistance chain 49, 50, 51, 52, 53, 54 and glow discharge tubes 42, 43, 44, which are supplied by a fullwave rectifier circuit. The output of valve 28 is applied to the grids of valves 22, 23 which are connected in a static phase-shifting circuit 24 of the kind described in Specification 633,754 which energizes the primaries of the saturable transformers 21, 32. The maximum angle of advance of the peaked voltages of transformers 21 and 32 is limited by a circuit of the type described in Specification 621,466 in which a voltage proportional to the anode-cathode voltage of valves 12, 13 is derived from the outputs of transformers 85, 86, and applied through the rectifier valve 82 to the grids of valves 22, 23. Variations in the voltage across resistor 29 regulate the phase shift of the peaked voltages applied to the grids of valves 12, 13 and 30, 31, to maintain the constancy of the resistor voltage and to stabilize the R.M.S. load current with supply voltage fiuctuations. Resistors 50 and 60 provide means for heat adjustment. Valves 12 and 13 may be used to fire immersion igniter valves controlling the load current.
