Title: Push-button control device for a radio or television tuner
IPC: H03J7/02
Filed: 1972-03-17
Abstract: 1376607 Push-button tuners PYE Ltd 17 March 1972 [29 April 1971] 12134/71 Heading H3Q [Also in Division H1] In a push-button control device for a radio or television varicap tuner with A.F.C. having a plurality of potentiometers 3 and a corresponding plurality of push-buttons 7, 8, each pushbutton has a first part 8 which, when the pushbutton is depressed, operates an associated switch for connecting the corresponding potentiometer into the tuning circuit of the tuner and co-operates with latching means 10-13 so as to be retained in the depressed position when the push-button is released and a second part 7 which operates A.F.C. cut-out means 20, 22 when the push-button is depressed and which returns to the undepressed position when the push-button is released, the A.F.C. cut-out means 20, 22 is operable by the second parts 7 of all the push-buttons and is arranged to remain in operation only while the second part 7 of one of the push-buttons remains in the depressed position and the second part 7 of each pushbutton also is rotatable to adjust the corresponding potentiometer to tune the tuner. When all the push-buttons 7, 8 are in their released position a pivoted plate 23 occupies the dotted position and the contacts 20, 22 of the A.F.C. cut-out switch 19 are open. When a push-button 7, 8 is pressed in as shown by 4c first the rear end 25 of the push-button moves the plate 23 about pivot pins 24 and closes the contact pin 22 on to spring blade contact 20 so as to short out the A.F.C. A cam surface 13 on outer sleeve 8 moves a locking bar to the right against the action of a spring to release any previously depresssed button and then a collar 9 closes a switch to switch the associated potentiometer into the tuning circuit. The locking bar now engages shoulder 14 to hold the sleeve 8 in. The fixed contact 20 is connected to the A.F.C. circuit and the movable contact is connected to a reference potential such as ground. On release of the pushbutton 4c the sleeve 8 is held in by the locking bar 10 and the rod 7 slides within the sleeve 8 and is returned by a spring 16 to its released position. This causes the plate 23 to move back to the dotted position so that the A.F.C. cut-out switch contacts 20, 22 open. Tuning adjustment can be made to the button which has been pressed by pressing in its rod 7 so that the plate 23 causes the A.F.C. cut-out switch contacts 20, 22 to close again. Then by rotating the rod 7 the spindle of the potentiometer 3 can be adjusted via gearing 25, 26. The wiper of the potentiometer is connected to a pin 3 which co-operates with a member 27 which is visible through a slot 24 at the front 5 of the tuner. Instead of the A.F.C. cut-out switch operating to short the A.F.C. it may be normally closed and arranged to open when the push-button is pressed so as to interrupt the A.F.C.

Patent GB-697226-A (GB)
Title: Improvements relating to the catalytic desulphurisation of petroleum hydrocarbons
IPC: C10G45/24
Filed: 1949-05-09
Abstract: A blended fuel suitable for use as a tractor vaporizing oil or power kerosene is passed in admixture with recycled hydrogen over a dehydrogenation-hydrogenation catalyst which is not poisoned by the presence of organic sulphur compounds, at a temperature and pressure to effect the conversion of a considerable proportion of the sulphur in the fuel to hydrogen sulphide and to produce a hydrogen-rich gas mixture which is separated from the treated fuel and recycled to the reaction zone as the sole source of hydrogen to the reaction zone and at a rate sufficient to maintain the necessary partial pressure of hydrogen therein.  The catalyst combines activity for dehydrogenation of naphthenes to aromatics with activity for the conversion of organically combined sulphur to hydrogen sulphide.  Suitable catalysts include metal sulphides and oxides, especially those of the 6th group of the Periodic Classification, used either alone (e.g. chromium oxide, tungsten sulphide), mixed with other sulphides and oxides (e.g. tungsten sulphide pelleted with nickel sulphide), in combination (e.g. cobalt molybdate or thiomolybdate), or mixed with or deposited on a porous support such as natural or processed bauxite, kieselguhr and alumina.  The preferred catalyst is cobalt molybdate supported on alumina.  The temperature at which the process is carried out may be between 700 and 800 DEG F, and the pressure may be between 50 and 250 lb./sq. in.  The pressure may be set at a predetermined level, excess gas being withdrawn, or it may be allowed to rise to an equilibrium pressure at which the hydrogen evolved equals the hydrogen consumed.  The hydrogen sulphide in the separated gas may be allowed to build up to an equilibrium concentration or it may be removed from the recycle gas.  If desired, the catalyst may be activated prior to its use in the process by treatment with hydrogen sulphide or a hydrogen sulphide containing gas.  The fuel to be treated may be a blend of an aromatic kerosine extract and kerosine with or without a naphtha, or a catalytically cracked fraction, kerosine and naphtha.  In an example a blend of 41 per cent of SO2-extracted kerosine, 33 per cent of kerosine and 26 per cent of naphtha (all by volume) is vaporized and passed to an autofining zone at 780 DEG F at a pressure of 100 lbs./sq. in.  The catalyst used is cobalt molybdate supported on alumina.  The gas produced is recycled to the autofining zone.  The sulphur content of the fuel is reduced from 0.544 to 0.05 per cent. Specifications 612,006, 654,152, 663,038, 669,536, 669,552, 669,553, 697,083, 697,222 and 697,227 are referred to.

Title: Treatment of zirconiferous materials
Inventor: EVANS ARTHUR WALLACE
IPC: C22B34/14
Filed: 1957-04-18
Abstract: In the recovery of zirconium values as soluble compounds from zirconiferous materials rich in silica, e.g. zircon sand, the finely divided zirconiferous materials are admixed with at least one finely divided alkali metal oxide, hydroxide, or carbonate, and at least one finely divided alkaline earth metal or magnesium oxide, hydroxide, or carbonate, and the mixture is then roasted, under conditions such as substantially to avoid fusion or sintering of the mixture.  The amount of alkaline earth metal or magnesium compound employed is preferably in the range of 0,2 to 1,8 stoichiometric equivalents per equivalent of zirconia+silica, and the amount of alkali metal compound is preferably in the range of 0,1 to 1,9 stoichiometric equivalents per equivalent of zirconia+silica.  The zirconium values may be recovered from the roasted product by digesting with a mineral acid, preferably in excess, and lixiviating with water, preferably at elevated temperature, to dissolve the zirconium.  The digestion with the mineral acid, for example hydrochloric or nitric, preferably sulphuric, acid, is carried out such that the treated material is in the form of a slurry, paste or, preferably, a substantially dry pulverulent mass. Advantageously dilute acid may be added during the lixiviation with water.  The mixing prior to roasting is preferably carried out in the dry state for example in a drum with vanes, or it may be mixed as a slurry or paste, and either dried or fed as it is to the roasting, which may be carried out in stationary or moving hearth furnaces either in crucibles or directly, or preferably either in batches or continuously in a rotary furnace in which it undergoes mixing during the roasting.  The zirconium sulphate solution obtained when the roast is digested with sulphuric acid may be used for incorporation with titanium dioxide pigments either by neutralizing the solution either in situ or prior to mixing with the titanium dioxide.  The thus coated or mixed pigment is then dewatered and dried.
