Filed: 1965-06-01
Abstract: 1,152,842. Mine roof supports. DOWTY MINING EQUIPMENT Ltd. 1 Sept., 1966 [1 June, 1965], No. 23302/65. Heading E1P. Lost motion is provided in the connection between a mine roof support and a conveyor to permit variation in the spacing between one end of an advancing jack and a pivotal member of the connection. A slot 36 is formed in a block 35 which is secured to the cylinder 11 of the advancing jack 9, and a bolt 39 carried by links 37, 38 of the connection passes through the slot. The links are connected to a flange 42 of a conveyor section 43 by a bolt 41, the flange being movable between the links 37, 38. A tapered guide 44 for limiting the angular movement of the jack parallel to the floor as the jack advances the roof support is secured at its wide end by the bolt 39 and at its narrow end is slidably located on the body of the jack. The guide 44 is arranged for cooperation with stop members 49, 51 secured to the inner edges of floor beams 1,2 of the roof support. The piston rod 13 of the' jack is secured to the floor beams 1, 2 by two pairs of chains 19, 22; 21, 23 and 28, 31; 29, 32. Eyes 24, 25, 33, 34 of the chains engage a pin 16 which extends through a block 15 of the piston rod 13 and shackles 19, 21, 28, 29 of the chains are secured to the-floor beams 1, 2. The chains permit movement of the jack 9, block 15 and pin 16 towards or away from the floor such that rubble trapped between the beams 1, 2 can pass underneath the jack and displace the jack upwardly without causing damage. When the jack is operated to advance the conveyer section the block 35 moves until the bolt 39 engages the end of the slot 36 nearer to the cylinder 11, or the outer end of the block 35 directly engages the flange 42 and the conveyer is advanced. As the conveyer section 43 advances, the permitted transverse angular movement of the jack 9 becomes larger and any lateral displacement of the conveyor due to snaking can be accommodated. In the final advancing movement of the roof support one or other of the floor beams 1, 2, makes contact with the conveyer section and the support is moved such that the beams extend approximately at right angles to the conveyor section. The small movement now permitted between the guide 44 and the stop members 49, 51 ensures that the jack is central of the beams 1,2.

Title: Method for the production and new applications of graphite metals
IPC: C22C1/02
Filed: 1937-09-03
Abstract: 500,657. Compositions containing metals. CUTLOHN, L. Sept. 3, 1937, No. 24156. Convention date, Sept. 3, 1936. [Class 70] Graphite metal is produced by adding to the molten metal or alloy to be graphitized a graphite-containing material in which the graphite has been deposited by the heat decomposition of a metal carbide. A suitable graphite-containing material is the mixture of graphite and calcium cyanamide obtained by heating calcium carbide in an atmosphere of nitrogen. In order to attain a high concentration of graphite, further graphite may be incorporated mechanically with the graphitecontaining material before addition to the molten metal. Thus dry graphite may be incorporated with the graphite - containing material or the latter may be incorporated in a dispersion of graphite in a liquid such as water or glycerine. It is stated that the graphite metals obtained according to the invention prevent the formation of coherent layers of calcareous deposit when used in the construction of boilers, water radiators, &c., and further, that they are resistant to the action of sea-water and other natural waters. The Specification as open to inspection under Sect. 91 comprises also the incorporation of the graphite by a vehicle which carries the graphite not only on its surface but also finely distributed throughout its entire mass, and the use of materials in which the graphite is deposited chemically by decomposition of carbon compounds. This subject-matter does not appear in the Specification as accepted.

Abstract: The invention comprises O,O-dimethyl-O-(4-cyanophenyl) thionophosphate.  It may be obtained by reacting O,O-dimethyl chlorothionophosphate with 4-cyanophenyl or an alkali metal salt thereof.  The reaction is preferably carried out in an inert organic solvent and substantially equimolecular proportions of the reactants are general employed.  When the free 4-cyanophenyl is used the reaction is preferably carried out in the presence of an acid binding agent, e.g. an organic base such as pyridine or diethylamine, or an alkali metal carbonate or bicarbonate. Suitable solvents are hydrocarbons, halogenated hydrocarbons, alcohols, ketones and ethers. A dehydrohalogenation catalyst, e.g. copper powder or a cuprous salt may also be present.  The product has insecticidal properties (see Division A5).ALSO:An insecticidal composition comprises an inert carrier and as active ingredient O,O-dimethyl O - (4 - cyanophenyl) thionophosphate (see Division C2).  The invention also includes a method of eradicating injurious insects, especially borers of rice, from a crop area containing a growing crop which comprises applying to the crop area an insecticide comprising O,O-dimethyl O-(4-cyanophenyl) thionophosphate.  The insecticidal compositions may be in the form of an emulsion, suspension, dust or oil preparation. In preparing the emulsion the active ingredient, which is stated to have low toxicity to warm blooded animals, may be mixed with an organic solvent, e.g. benzene or xylene, and a non-ionic surface active agent to form an emulsifiable concentrate suitable for dilution with water before use. Wettable powders may be obtained by mixing the active ingredient with a non-ionic surface active agent and a powdered carrier and are then added to water to form a suspension.  Dusts may be formed by mixing the active ingredient with a powdered carrier with or without the use of a volatile solvent, e.g. acetone.  Oil preparations may be obtained by dissolving the active ingredient in a solvent such as deodorized kerosene if desired with the use of a co-solvent, e.g. an aromatic hydrocarbon such as benzene, xylene or methylnaphthalene.  A fungicide, herbicide or other insecticide may also be present.

Abstract: 854,873. Densimeters. NATIONAL RESEARCH COUNCIL. July 15, 1959 [July 29, 1958], No. 24368/59. Class 40 (1). [Also in Group XX] To measure the density of a liquid sample, a vessel 14 is filled with the liquid and shaft 20 rotated so that unbalance causes transverse oscillation of the shaft against the action of springs 35 bearing against a bush 34, the amplitude of oscillation being a measure of the density. This amplitude is measured by means of a rod 58 connected at one end to bush 34 and carrying at its other end a coil 61 cooperating with permanent magnet 63 to produce signals which are amplified and indicated or recorded at 65. Alternatively a crystal pick-up may be employed or electrostatic measurement employed making an element connected to bush 34 one of the plates of a capacitor. In a modification the amplitude of oscillation is measured by optical means or the coil-springs 35 are replaced by leaf-springs and a strain gauge is attached to one of the springs. The vessel 14 is pivoted at 15 in plates 16, adjusting screws 18, 21 being provided so that on filling the vessel 14 with pure water and rotating the shaft 20 at constant speed, the system may be made to balance so that the amplitude of oscillation is zero. Closure 29 is then removed, pivoted flaps 52, 56 raised, and vessel 14 tilted anticlockwise to empty the water into a waste pipe 54. The vessel 14 is  tilted back to its normal position, filled with sample liquid and closure 29 replaced, the assembly then being rotated through shaft 20 at the constant speed and the magnitude of oscillation observed. A valve 26 allows flushing out the vessel 14 between samples.
