Title: Improvements in or relating to extrusion press run-out table
IPC: B21C35/02
Filed: 1961-11-20
Abstract: 934,597. Extruding. T. E. HUTCH. Nov. 20, 1961, No. 41441/61. Class 83 (4). [Also in Group XXX] A run-out table for an extrusion press comprises a moving link belt conveyer.

Title: Single lens reflex cameras
IPC: G03B17/18
Filed: 1972-09-07
Abstract: 1409313 Cameras ASAHI KOGAKU KOGYO KK 7 Sept 1972 [9 Sept 1971] 41633/72 Heading G2A An SLR camera has a TTL light measuring and shutter control circuit Fig. (not shown); a changeover member 17 which in a vertical position switches into the shutter control circuit a resistor 4 couplable to an objective 9 arranged to have its aperture fully open during light measurement and in an inclined position switches out the resistor 4 to enable the use of objectives whose apertures are stopped down before light measurement; and means which, when the member 17 is set to the vertical position but an objective which does not couple with resistor 4 is used, disables a hold-on arrangement which normally holds the power source switch S1 closed and/or causes a bulb exposure to be made. Both actions save battery power. As shown, in normal use depression of release 8 rotates a lever 20 to close power source switch S1, and a hold-on lever 23 rotates into position over lever 20 to keep S1 closed until shutter closure causes a gear 33 to move lever 23. When objective 9 is used it couples to a ring 13 to adjust resistor 4. When a non-coupling objective is used ring 13, is free to rotate and a projection 13a moves a lever 14 to tighten a wire 29 attached to lever 23. When wire 29 is tightened by lever 14 and is additionally tightened by lever 17 being positioned vertically, then it pulls hold-on lever 23 away from lever 20 and the switch S1 remains closed only as long as the release 8 is depressed, i.e. a bulb exposure is made. Alternatively, the hold-on arrangement is not affected, but return movement of release 8 de-energizes a shutter holding electromagnet (7), again to make a bulb exposure.

Adiponitrile is continuously produced by hydrogenating 1,4-dicyanobutenes in the liquid phase at 50-200 C. using at least one mole of hydrogen per mol. of 1,4-dicyanobutene and employing a catalyst comprising palladium and silver in the form of the oxides or the metals. The reaction may be effected at atmospheric or superatmospheric pressure (e.g. 50-300 atmospheres gauge) in an inert solvent, e.g. a nitrile, an unsubstituted or alkyl-substituted aromatic hydrocarbon, an aliphatic or cycloaliphatic hydrocarbon or a lower, i.e. C 1-8  aliphatic alcohol. The catalyst may also contain nickel, cobalt, manganese or vanadium in the form of the metals or oxides, promoters, e.g. compounds of Groups I to III and/or VI of the Periodic Table, may be added and the catalyst may be unsupported or supported, preferably on a siliceous carrier. A mixture of 1,4-dicyano-1 and -2-butenes may be employed as starting material and hydrogen is generally employed in an amount which is twice that required stoichiometrically. The oxidic catalysts may be wholly or partially reduced prior to use and they may be employed in the form of spheres, pellets or extruded pieces.

Title: Burned brick
IPC: C04B35/03
Filed: 1964-10-16
Abstract: A ceramically bonded refractory shape is produced by blending dead-burned dolomite, dead-burned magnesia, hard-burned lime or mixtures thereof with 1-2% by weight of a molten saturated fatty acid pitch, forming a shape and firing at, for example, 2500-3000 DEG  F. "Saturated fatty acid pitch" is defined as the residual material obtained by fractional distillation of animal and vegetable materials such as lard, tallow, palm oil, other vegetable oils, bone fat, garbage, sewage, woolgrease and packing-house waste, and the preferred pitch contains 10-20% free fatty acids and 10-30% unsaponifiable organic material, has an acid number of 20-40, and has a maximum iodine value of 10.  The pitch, which is solid at room temperature (70 DEG  F.), should soften between 120 DEG  and 450 DEG F. and preferably between 120 DEG  and 250 DEG  F. The refractory may be blended with up to 3% molten medium or hard pitch simultaneously with the fatty acid pitch; medium and hard pitch can be derived from petroleum or coal and have softening-points 150-250 DEG  F., 275-450 DEG  F. respectively. Preferably fatty acid pitch and medium pitch are used in 1:3 ratio.  The refractory may consist of up to 50% magnesia containing at least 95% MgO, not more than 1% Al2O3 and Fe2O3 and the remainder CaO and SiO2 in a 3-4: 1 ratio, with the balance of the refractory being dolomite. Preferably 50-65% of the refractory is +65 mesh (Tyler) the remainder being -65 mesh. In an example dead-burned magnesia analysing at least 97% MgO is bonded with the fatty acid pitch defined.

Title: Dyestuffs derived from naphtholactams, and process for their production and use
IPC: C09B57/06
Filed: 1965-10-06
Abstract: The invention comprises dyestuffs of the formula <FORM:1058509/C4-C5/1> wherein R represents H, alkyl, aralkyl, cycloalkyl or aryl; R1 represents H or alkyl; and X represents an anion which may be monovalent or polyvalent; the aromatic rings and the radicals R and R1 may contain non-ionic substituents but should be free of COOH and SO3H groups.  They may be obtained by condensing compounds of the formula <FORM:1058509/C4-C5/2> (see Division C2 for preparation) with indole derivatives of the formula <FORM:1058509/C4-C5/3> in the 3-position in the presence of a condensation agent, and, in the case in which R represents H, the dyestuffs, which may be obtained in the form of the salts, are converted, if desired, into the bases from which they are derived, which may be followed by quaternization. Specified non-ionic substituents are halogen atoms, alkyl, alkoxy, NO2, amino, acyl, sulphonamido and non-ionic derivatives of carboxylic groups.  The condensation may be carried out in an inert solvent.  Specified condensation agents are acid chlorides.  Friedel-Crafts catalysts may be added. Examples are given for the production of the dyestuffs. They may be used for dyeing, printing and spin-dyeing of synthetic or semi-synthetic materials, e.g. of synthetic superpolyamides, acetate rayon, cellulose pulp; or leather yellowish red to blue shades, and are particularly useful for dyeing polyacrylonitrile and polyvinylidene cyanide.ALSO:1 - Methyl - 2 - ethyl - naphtholactam - (1,8) is obtained by condensing 2-ethyl-1-amino-naphthalene with COCl2, treating with anhydrous AlCl3 giving 2-ethyl-naphtholactam-(1,8) and treating this compound with dimethyl sulphate in the presence of KOH and dimethyl formamide as solvent. The naphtholactams are useful as intermediates in the formation of dyes (see Division C4).

Title: Method of dissolving metallic oxides and borides, and of extracting uranium values
IPC: C01F3/00
Filed: 1962-11-12
Abstract: A solution containing at least one of the components of a chemically highly stable ceramic or green powder for the formation of such a ceramic is prepared by treating the ceramic or powder with a solvent comprising an aqueous acid, and mercury or silver in a concentration as low as 0.01 M.  The ceramic or powder consists of one or more of the oxides of U, Be, Zr, or Al, or borides of Zr or Ti.  The powder may contain a hydrocarbon binder. The Ag or Hg may be added in elemental form or as a compound, e.g. a chloride or nitrate. The ceramic may be powdered to 100 mesh U.S.S. or finer, and slurried with water.  The temperature may be raised to expedite the reaction. The acid used may be e.g. one or more of HCl, HF, other hydrogen halide acids, HNO3 or H2SO4.  Be and U values may be separated from a solution prepared as above from beryllium oxide-uranium oxide material by liquid solvent extraction.  The U is oxidized from the quadrivalent to the hexavalent state, e.g. by H2O2 or KMnO4; Al(NO3)3 or Be(NO3)2 is added to supply nitrate ions.  An organic solvent, tributyl-phosphate (TBP) or methyl-isobutylketone (Hexone) is added to extract the uranium nitrate as a complex.  Specification 1,010,558 is referred to.

Under normal conditions the valve 16 is upright to prevent escape of compressed air when the trigger 6 is pulled to deliver air from the reservoir 2 through the release valve 11 and channel 12 to lift a control valve 7 which in turn causes the intake valve on the cylinder 5 to open. When the magazine is empty a projection 22 on the magazine slide block 21 tilts the valve 16 so that when the trigger 6 is pulled the compressed air passes through a channel 12a to atmosphere instead of operating the control valve 7. An acoustic warning signal may be given off by the air escaping through the valve 16.
