Title: Process of producing Acrylonitrile
Inventor: ANDERSON GEORGE CHARLES
Filed: 1967-03-28
Abstract: 1,178,746. Ammoxidation of propylene. EASTMAN KODAK CO. 28 March, 1967 [25 March, 1966], No. 14105/67. Heading C2C. Acrylonitrile is obtained by contacting a vapour-phase mixture containing ammonia, oxygen and propylene with a solid catalyst composition consisting essentially of a calcined mixture of an oxide or an acid or a salt of molybdenum and at least one of an oxide or a salt of niobium and an oxide or a salt of tantalum at a temperature at least high enough to cause the ammonia, oxygen and propylene to react together to form acrylonitrile and water. The catalyst may also comprise an oxide of arsenic and the arsenic content in the catalyst may be controlled by continuously or intermittently vaporizing As 2 O 3  into the vapour phase mixture which is contacted with the catalyst. The mol ratio of ammonia : oxygen : propylene is generally in the range 0.2 : 0.5 : 1 to 2 : 4 : I and the catalysts, which suitably contain by weight 1-34% Mo, 0.5 to 35% Nb or 0À75-41% Ta and 0-19% As, may be supported. The reaction may be effected by a fluidized bed process at 300-550‹ C. employing a contact time of 0À1-20 seconds, an inflammable or non- flammable diluent may be present, and the catalyst may subsequently be regenerated by oxidation, e.g. with an oxygen containing gas.

Abstract: 976,054. Bearings. MASCHINENFABRIK OERLIKON. April 9, 1963 [April 13, 1962], No. 14192/63. Heading F2A. A plain bearing for a shaft 1 having a ring 2 fixed thereon which raises lubricant from a reservoir, comprises a housing 3 which supports an axially displaceable doctor-blade 4, has an outlet port 8 therein which leads to a rising pipe 10, or to a valve 13, connected to an oil cooler (not shown) and has by-passes 11 and grooves 12 therein for the purpose of emergency lubrication. The doctor-blade 4 is fitted in a groove in the housing 3 and, when the shaft 1 rotates in the direction of the arrow 6, lubricant is conveyed from the reservoir through an opening 7 in the housing to the doctor-blade and is passed through the port 8 at a high pressure. The lubricant then passes through the cooler to lubrication-grooves (not shown) of the bearing. Clearances 9 are provided between the housing and the doctor-blade to allow for axial movement of the latter which may take place due to expansion or contraction of the shaft.

Title: Improvements in locomotive boilers
IPC: F22B13/14
Filed: 1920-05-26
Abstract: 168,374. Hawley, C. G. May 26, 1920. Fire-boxes; partitions in water space; water chambers in fire-boxes. - In a locomotive boiler provided with one or more water-circulating elements S in the fire-box, means are provided to divide the flow of water between the water legs of the boiler and the circulating elements. An inverted trough C open at the forward end and strapped or spot welded to the boiler has a leaky telescopic connection 22, closed at 22a, with the intake S<1> of the circulating element S, which is preferably of the type described in Specifications 137,093 and 146,905 as shown. The boiler feed enters at 17 so that a full-length circulation of the water in the boiler takes places as indicated by the arrows. In a modified arrangement in a boiler with a forwardly extending combustion chamber, longitudinal vertical plates attached to the boiler shell extend under the combustion chamber from its forward end to the throat sheet 15 and down to the mud ring 7 so as to form an intake channel for two circulating elements. The plates may be extended past the forward end of the combustion chamber through the medium of a trough-like member. In boilers with barrels of large diameter, the elements S enter the throat sheet on a level with the bottom of the water barrel, and the intake channel C becomes a straight duct, the depending portion of the telescopic connection only being preserved where necessary to admit the wash-out plug 24.

[Class 98 (i)] A diaphragm defining the cross-section of a beam of X-rays or gamma rays falling upon a plane element, e.g. a fluorescent screen or photographic sensitive surfaces, is mounted parallel to the element on a longitudinally extensible member, connecting the source to the element, at a point which moves, as said member is extended or contracted, through a distance which is in constant ratio to the extension or contraction of the member. With such arrangement, the cross-section of the beam where it falls upon the element remains constant irrespective of the extension or contraction. The aperture of the diaphragm may be adjustable. The member may be of lazytongs form, the diaphragm being connected to one of the central or lateral pivots ; or it may be a uniform coiled spring or elastic cord, the diaphragm being connected to any point therealong. If several diaphragms are used to reduce penumbral shadow, they may be located at different pivots of the lazy-tongs or at different points along the spring or cord. The diaphragm and plane element need not be normal to the axis of the beam. Guides or runners may be provided to support the weight of the source, diaphragm and plane element.

Filed: 1974-04-04
Abstract: 1465953 Fluid-pressure servomotor systems HOPKINSONS Ltd 4 April 1974 14954/74 Heading G3P A fluid-flow control valve comprises differential pressure switch means between its inlet and outlet to detect abnormal flow conditions and to actuate a pilot operated valve closing system. The valve may be a main steam isolating valve in a light water nuclear reactor system and includes a gate 14 having a spindle 16 normally controlled by a hydraulic actuator. Spindle 16 also carries a piston 18 having a bleed port 19 such that the steam pressures on opposite sides of the piston are equal during normal operation with emergency pilot valve 22 closed. Pressure tappings A, B, C are provided in the venturi-shaped valve body 15 and connected via lines 32 to pressure switches 25. Should either of the latter be closed by a pressure differential indicative of abnormal flow then an electric signal causes solenoid valve 24 to vent air from above the piston 40 of pneumatic actuator 23. Valve 22 thus opens causing steam pressure above piston 18 to be vented through lines 20, 21 with consequent closing of gate 14. An "open" and "closed" light indicating switch (44) Fig. 3 (not shown) is associated with valve 22. Each pressure switch 25 comprises a pair of opposed liquid filled bellows the motion of which is transmitted through a torque tube to operate limit switches. An additional temperature compensating bellows is provided. The electric circuitry may include electronic relays (46) Fig. 5 (not shown).

Title: Production of non-woven materials
IPC: D04H1/425
Filed: 1966-04-05
Abstract: 1,141,162. Nonwoven fabrics; water-proofing. CARL FREUDENBERG. 5 April, 1966 [7 April, 1965], No. 15129/66. Headings DIP and D1R. In a process in which a nonwoven material is produced by forming fibres into a loose fleece and applying a bonding agent to the fleece as an aqueous solution or dispersion, and in which a substantial proportion of the fibres are normally hydrophilic, that is of such nature that the loose unbonded fleece will collapse to a small fraction of its thickness if dipped in water, substantial collapse is avoided by rendering the fibres hydrophobic by treating them with a water-repelling agent before forming them into the fleece. The fibres may be of wool, linen, or regenerated cellulose. Water-repelling agents that may be used are mixtures of paraffin wax emulsion and aluminium triformate, and a partially etherified melamine-formaldehyde resin in which part of the ether groups are substituted by fatty acids. Non-hydrophilic fibres e.g. of polyvinyl chloride may also be present. In the Examples, the binders are; (1) a cross-linkable acrylate resin dispersion, ammonium oxylate and water; (2) a chlorine-containing film-forming compound and antimony trioxide; and (3) a cross-linkable acrylic resin dispersion, antimony trioxide and ammonium oxalate. The products of Examples 2 and 3 are only slightly inflammable. Similar results can be obtained by the use of other flame-retarding metal oxides, particularly if the binder or fibres or both contain chlorine.
