Title: Hoist Mechanism for Bucket
IPC: E02F3/48
Filed: 1969-02-20
Abstract: 1,198,232. Winding arrangements. RUSTONBUCYRUS Ltd. 20 Feb., 1969 [4 March, 1968], No. 9126/69. Heading B8B. [Also in Divisions E1-E2] A hoist mechanism-for the bucket 13 of a dragline excavator comprises two independently driven drums 14, 15, a pair of cables 16, 17 and 18, 19 extending from each drum, and a suspension arrangement which together with the torque/speed characteristics of the drum drive motors, results in an equal sharing of the load of the bucket 13 by the drums. The bucket is supported by a suspension bar 23 which at one end has a rigid beam 27 and at the other end has a pivoted equalizer beam 25, one cable from each of the drums being coupled to opposite ends of each of the beams 27, 25. Any difference in the torque of the drums 14, 15 is balanced out in the cables 16, 18 due to their connection to the pivoted beam 25, but results in a difference in force in the Gales 17, 19 attached to the rigid beam 27. The motors driving the drums 14, 15 produce low torque at high speed, and therefore, any difference in torque between the two drums will result in the higher torque drum slowing down while the lower torque drum speeds up until the torques are equal, whereupon the two hoist drums are kept substantially in step at all times. The beams 25, 27 are each connected to the suspension bar through universal joints 26. A block 29 for the bucket dump rope 30 is mounted on the suspension bar 23, the rope extending between an arch 31 on the bucket, and the drag rope 34.

Abstract: 1413901 Drying articles I SCHUBERT, A SCHUBERT and F SCHUBERT [trading as E HEINE NACHF & INH ALFRED SCHUBERT KG] 23 Feb 1973 [25 Feb 1972] 9128/73 Heading F4G A method of drying an article comprises placing the article in a boiler which is then hermetically sealed, boiling water in the boiler to produce on predetermined elevated steam pressure, allowing the article to dry in the steam for a predetermined time with the temperature of the steam falling, discharging the steam from the boiler and then allowing air to circulate about the article to finish the drying process. The apparatus for carrying out the method has a plurality of accommodation plates each covered with a porous stone to form a condensation shield. Water is supplied to the boiler by a pump 11 and discharged from the boiler through a valve 14. The water is heated by a thermostatically controlled oil fired system 14, the system also being controlled indirectly from a heat sensitive element (17). Steam is discharged through a valve 29 and a fan 26 is provided to create the circulation of air which air enters the boiler through a valve 20. The boiler is provided with a flue gas jacket 21 and an insulated lid.

Abstract: 1375055 Refining Cu/Fe sulphide to form Cu and Fe sulphate, CuS 2 , FeSO 4 , Iron oxide elemental sulphur and jarosite COMINCO Ltd 28 Feb 1972 [5 March 1971] 9138/72 Heading C1A A process for treating complex copper-iron sulphides for the recovery of copper values and sulphur in elemental form, comprises reacting the sulphides with an activation leach consisting of sulphuric acid and metallic copper at 70 to 100 C. to dissolve the iron as iron sulphate and leave the copper as insoluble copper sulphide. The ferrous sulphate solution is then separated and oxidized and hydrolyzed to precipitate the iron compounds and regenerate the acid solution which is then separated from the iron compounds and recycled to the activation leach. The insoluble copper sulphide is subjected to an oxidizing leach to convert the sulphide to elemental sulphur and dissolution of copper as cupric ion in solution. The copper, dissolved as cupric ion can be recovered from the solution, as metallic copper either by hydrogen reduction by bubbling hydrogen into the solution, or by electrowinning.

Abstract: 568,947. Floors; walls. DEHN, F. B.. (Lock-Seal Co.). June 10, 1943, No. 9363. [Class 20 (iv)] A wall, Fig. 1, or a floor, Fig. 7, is composed of a number of spaced plates having ribs 13, 14 formed with undercut bevel faces, the plates being spaced apart by channel-shaped tie plates 15 having bevelled flanges 16 on their inner faces for engaging the ribs, the tie plates being arranged in pairs and being held in their locking position by a filler such as concrete. As shown in Figs. 1 and 2, the wall plates 10 have end flanges 11 and a central projection 12, these being disposed between the ribs 13 and 14 respectively in the assembled structure. Some of the plates are formed without the members 12, 14, as shown in Fig. 1, so that opposing plates of the remainder of the wall break joint with respect to each other. The corner plates 18 have marginal grooves 19 which receive the flanges 11. In constructing the floor and ceiling construction shown in Fig. 7, the plates are held up by temporary supports and spaced apart by the tie plates. The floor plates 23 are shorter than the ceiling plates 22, thus providing spaces 25 for introducing the concrete filling 24, the latter being carried across the floor with the end portions supported on the walls. In a modification, the tie plates are formed with projections upon which are seated boards of insulating material arranged between the floor or wall plates. The wall plates may be made of fire clay, cement, glass or asbestos.
