Title: Improvements in connectors for detachably joining the ends of a length of belting
IPC: F16G7/00
Filed: 1962-01-26
Abstract: 988,876. Belt fastenings. G. V. IRELAND. Jan. 26, 1962 [Feb. 3, 1961; Sept. 11, 1961; Dec. 21, 1961], No. 3021/62. Heading F2Q. In a fastening for V-belts wherein a detachable link 16 shaped as shown in Fig. 5 hingedly interconnects slotted U-shaped saddles 14, 15 nailed or riveted to the belt ends, the slot 31 in each saddle communicates with an opening 25 wide enough to allow the link 16 to be passed therethrough and then turned through 90 degrees to seat as shown in the saddles. The opening 25 is formed by bending down a lug 23 which engages the end face of the belting to position the saddle during nailing. After insertion of the link 16 each lug 23, which has a hole to receive a tool, may be bent up as shown about a weakened portion to block the opening 25 and prevent accidental disengagement of the link. The link 16 shown is made of nylon or other plastics material moulded around a sheet metal core. In a modification, Fig. 6 (not shown), the transverse ends of the link are displaced downwardly relatively to the stem so that the stem and ends are tangent to a common plane.

Title: Improvements in or relating to the froth flotation and other concentration of minerals
IPC: B03D1/02
Filed: 1934-01-30
Abstract: Gold is concentrated from gold ores by forming the ore in finely-ground condition into a pulp with water in the presence of a mercurial reagent such that the surfaces of the gold particles present are modified by the reagent and then separating the gold from the ore by film or froth flotation.  The mercurial reagent may be mercury or a mercury salt, e.g. mercuric cyanide and free alkali cyanide.  Mercury, if used, is not used in an amount sufficient to effect amalgamation.  The mercurial reagent may be introduced into the ore pulp during a preliminary agitation or grinding.  In conjunction with the mercurial reagent may be employed a sulphidizing agent, e.g. an alkali polysulphide, an alkali sulphide, or sulphur, or an organic sulphur derivative of carbonic acid, e.g. an alkali xanthate, or a fatty acid such as oleic acid, or a tin salt such as stannous chloride, or a mixture of two or more of these substances. A tin salt may be mixed with a mercury salt solution and the mixture warmed to precipitate mercury before adding to the pulp.  Flotation oils such as fuel oil, creosote, and pine oil may be added to the pulp during or before the grinding stage and the separation effected by froth flotation in a subaeration machine with the aid of xanthate. Mercury may be worked up into an emulsion with fuel oil before its addition to the circuit.  When separating by film flotation the ore may be ground in a pulp with the mercurial reagent, a sulphidizing agent, and an oil and then deslimed and passed several times over a spitzkast of the type described in Specification 7803/05, [Class 82].

Abstract: 693,902. Valve circuits for radio reception. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 13, 1950 [Feb. 16, 1949], No. 3615/50. Class 40 (v). A frequency-changing arrangement comprises a valve with three, or more, grids in which the inner grid and anode together with the screen grid are back-coupled so as to produce oscillations, the signal being applied to the inner grid and a gain-controlling potential to the outer grid. The anode circuit comprises an I.F. output transformer 15 in series with the oscillator circuit 17 which is back-coupled to the inner grid by means of a coupling coil 6. The signal input circuit 2 is coupled via a filter network 4, 5, provided to reduce radiation of local oscillations, to a tap on the coil 6, which is connected to earth via a condenser and resistance 18. The arrangement is such that in conjunction with the input impedance of the valve a balanced network is formed, so as to avoid radiation of the local oscillations. The screen grid 10 of the valve is connected via a blocking condenser to the join of circuits 15, 17, the valve being effectively connected as a triode for the purpose of generating oscillations; thus variation of the potential of the outer grid, while varying the output, does not affect oscillation. In an alternative embodiment, Fig. 2 (not shown), the tuned oscillator circuit 17 is placed in the cathode lead.

The process may be carried out with the reactants in solution, or in the solid state, and additional reagents may be present, e.g. aldehydes or aldehyde-forming compounds, hydrochloric acid, or catalysts such as aluminium chloride or sulphate, or ammonium chloride.  Phosphoric acid may also be present with the phosphates used.  Specified starting materials include starch, amylose, amylopectin, dextrins, agar, alginic acid, galacto-mannan, and plant gums, either natural or pre-treated by oxidation, hydrolysis, enzymes, irradiation, mechanical or supersonic degradation.  Specified nitrogen compounds are urea, thiourea, methylol ureas, formamide, trimethylamine, triethanolamine, hexamethylene tetramine and ammonium carbonate.
