Inventor: KASSEL LOUIS STEVENSON
IPC: C07C5/10
Filed: 1956-07-10
Abstract: 794,553. Cyclohexane. UNIVERSAL OIL PRODUCTS CO. July 10, 1956, No. 21297/56. Drawings to Specification. Class 2 (3). Cyclohexane is prepared by the catalytic hydrogenation of benzene with a stoichiometric excess of hydrogen at elevated temperature and pressure in a plurality of contacting zones, hydrogen, cyclohexane and part of the benzene charge being introduced into the first zone at a temperature of 160-205‹ C. and the effluent from each of the zones except the last being cooled by indirect cooling and by admixture of benzene to within 160-205‹ C. Preferably benzene is fed in equal quantities to each contacting zone. Cyclohexane and hydrogen are fed with a portion of the benzene to the first zone in amounts such that the proportions of cyclohexane and hydrogen are 0.5 to 3.0 and 4 to 50 mols. per mol. of total benzene charge respectively. The cyclohexane is added as a diluent. Preferred conditions in the contacting zones are 7 to 35 atmospheres pressure and 260-316‹ C., and the amount of benzene fed to each stage is adjusted so that the temperature does not rise above 316‹ C. The effluent from the last zone is cooled to condense the cyclohexane, part of which is recycled to form the cyclohexane feed to the first zone and the gaseous phase, principally hydrogen, is also recycled. Two to eight zones may be used, four being particularly convenient. Specified catalysts are nickel, palladium, platinum, iron, and " Raney " (Registered Trade Mark) nickel, preferably on a carrier of alumina, silica, kieselguhr, diatomaceous earth, magnesia or zirconia.

Abstract: 532,528. Fabrics composed of agglutinated fibres. ALGEMEENE KUNSTVEZEL MAATSCHAPPIJ N.V. July 24, 1939, No. 21444. Convention date, July 26, 1938. [CLass 140] A fibrous bat is composed of loosely intermatted inorganic fibres and a bonding agent including a thermo-setting condensation product coating the constituent fibres with a thin film which is insufficient to alter materially the physical properties of the individual fibres but bonds these together at their points of contact without substantial reduction of the interstitial spaces between the fibres. The condensation product may be a phenol-formaldehyde, ureaformaldehyde, or alkyd resin ; and the fibres may be glass, slag, or rock wool. The resin may be added to the lubricating mixture usually applied to glass fibres during manufacture ; or this lubricant or other oily or fatty material (e.g. fatty acids, petroleum oil, metallic soaps, waxes) and the resin may be emulsified in water and sprayed on to the fibres during matting. The bat may comprise ¢ to 2¢ per cent. resin. After application to the fibres, the bonding agent is set by heating, e.g. between rollers or belts or in cavities such as the hollow panels of refrigerators and stoves. The material may also be used for insulation in houses and railway and road transport vehicles. The Specification as open to inspection under Sect. 91, refers also to the use of bentonite as an emulsifier. This subject-matter does not appear in the Specification as accepted.

Patent GB-1097455-A (GB)
Title: Method of monitoring and regulating the oxygen blowing process
IPC: C21C5/30
Filed: 1965-05-21
Abstract: The oxygen blowing process for steel production from pig iron, e.g. in a top blown converter, is monitored and automatically regulated by an oxygen distribution parameter (equal to the ratio of the carbon oxidation rate to the pressurized oxygen flow) continuously calculated from the pressurized oxygen flow and waste gas flow values as well as the CO2, CO, O2 and H2 contents in the waste gas, which are continuously measured and transmitted to an electronic computer, and compared with a set value of the parameter, the oxygen flow-rate, the level of the oxygen blowing lance and/or the addition of flux to the bath being adjusted automatically until the measured and set values agree.  The set value may be adjusted manually or by feeding a function varying with the oxygen blowing time into the computer; this function may be corrected by further measured values e.g. bath temperature, converter noise intensity, conductivity between lance and bath, the rate of carbon combustion and the total of carbon burnt in the bath.

Abstract: 1,173,137. Mass spectrometers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 10 May, 1967 [17 May, 1966], No. 21826/66. Heading H1D. In a mass spectrometer the total effective exposure of a photographic plate or other integrating ion-detector is synthesized from two or more successive individual exposures, the succession of individual exposures being terminated automatically at a predetermined number or when the charge laid down on the detector reaches a predetermined value, the individual exposures preferably being of equal duration in time. The charge is monitored on a collector having a slit through which about half of the ions will pass when the beam is in focus in front of the photographic plate, the collector being connected to a capacitor storage circuit which automatically terminates the succession of exposures. This is effected by control of a relay for disconnecting a pulse amplifier controlling the operation of an ion beam chopper which, as shown, comprises a deflector slit 2 defined by the parallel flanges 4, 6 of two halfplates 8, 10. Half-plate 10 and further upstream and downstream plates 16 and 22 are earthed while a deflecting potential is applied to the half-plate 8 to allow the ion beam periodically to pass through the system. Halfplate 8 may be periodically varied between zero and a positive potential to repeatedly switch the beam into the slit 2 or made alternately positive and negative to repeatedly sweep the beam across the slit 2, preferably at a constant rate. The ion source of the spectrometer is of the spark type preferably of the type disclosed in Specification 21825/66. The ion beam chopper assembly shown is preferably located immediately after the ion source and before the electrostatic analyser.
