Title: Hoisting winch in particular for a boring machine
IPC: B66D1/44
Filed: 1973-10-03
Abstract: 1439624 Hydraulic winches BENOTO-SAM 3 Oct 1973 [3 Oct 1972] 46226/73 Heading B8B A winch for hoisting a load and allowing the load to fall freely includes a cable drum 11 driven by a reversible hydraulic motor 8 whose rotor is connected to the drum and is capable of rotating freely with respect to the stator upon application of an auxiliary control pressure to the rotor. The motor 8 has supply and return ports 8a, 8b for powered winding in or paying out, and a control port 8c which when pressurized disconnects the drive between stator and rotor of the motor 8. A band brake 13 is normally applied to the drum 11 under spring pressure, which spring is compressed by fluid pressure to release the brake automatically when pressure is supplied to drive the motor and also when a cylinder device pilot valve 51 is manually operated to produce the command control pressure at motor port 8c for free fall condition of the drum. The control pressure generated by the valve 51 is limited by a calibrated relief valve 57 in line 56, and is also fed through line 58, and check valve 59 to safety pressure relief valves 44, 45 where the control pressure suppresses the pressure setting of these valves 44, 45 which are set to short circuit the pressure from the main pressure supply pumps 29, 30 to tank upon a predetermined limit which sets the motor torque available, being exceeded. This prevents the supply of pressure to drive the motor whilst the free fall condition exists. The main pressure pumps comprise high and low output pumps 29, 30 enabling the motor to be driven at different speeds, the supply from the pump 30 being controlled by a manual direction control valve 35 and that from the pump 29 by a similar valve 42, the two supplies being connected in series for supply to the motor. The valves 35, 42 permit progressive control of the rate of flow of hydraulic fluid therethrough to control the motor speed within the range of the appropriate pump delivery rate. An accumulator 55 in the line 54 between the valves 51 and motor part 8c absorbs fluid from the motor housing when motor drive is selected and assists the pressure from the valve 51 when the drive is neutralized for free fall.

A number of baffle plates 19 extend laterally from the container 7 to engage spacers 17 of the outer fuel assemblies 10c. Further baffle plates 20 are disposed between the baffle plates 19 but these do not extend as far as the core 2. In the embodiment described the space between the container 7 and the spacers 17 is sealed off in a fluid-tight manner by the baffle plates 19 but this is not an essential feature. The coolant enters the reactor vessel 1 through an inlet port 3 and flows down between the vessel 1 and the container 7 before flowing up through the core 2 to an outlet port 4. Coolant leaving the core 2 through its sides is forced back in again by the baffle plates 19 and this alternating movement of the coolant affords good mixing in the marginal fuel assemblies of the core. The reactor is provided with guide strips 21a, 21b, 21c which serve to guide the outer fuel assemblies on their introduction to or extraction from the core. The guide strips, which extend parallel to the longitudinal axis of the core, may be provided over the entire length of the core.

Title: Hydrometallurgical method for the direct extraction of metals from minerals and other substances
IPC: C22B3/10
Filed: 1962-12-17
Abstract: A metal is selectively removed from a metal-bearing material by leaching with aqueous HCl, separating the solution, selectively crystallizing and separating the chloride, reducing the chloride to metal by heating in H2 below its melting point, and hydrolysing the liquor to give HCl gas, which is absorbed in water and recycled.  The metal may be Fe, Co, Ni, Sn, Zn, or Cu.  In the example, FeCl2 is reduced at 575-675  DEG C., e.g. in H2 given off in the leaching process, thus generating a mixture of H2+HCl which may be used to dehydrate the crystals prior to reduction, or the HCl may be absorbed and the H2 recycled. Product Fe is cooled in H2 or inert gas, scrubbed with water to remove soluble chlorides and dried.  In Fig. 7 (not shown), metal chloride is fed from inert atmosphere hopper 66 via vibrating feeder 70 into tube 60, along which it is carried by rotating paddles.  H2 is passed along in counter-current.ALSO:A metal chloride is obtained by leaching a metal-bearing material with aqueous HCl, separating the solution, selectively crystallizing and separating the chloride, and hydrolysing the resulting liquor to give HCl gas which is absorbed in water and recycled.  The metal may be Fe, Co, Ni, Sn, Zn, or Cu.  The crystals may be washed, filtered, and at least partially dehydrated (wash liquor and water removed being recycled) and are then heated in H2 below their melting point to give the metal.  The metal-bearing material may first be crushed and partially reduced below 1000 DEG  C. to render it acid soluble.  In the example, Fe3+ is reduced with coal at 750-875 DEG  C. to Fe2+ and then leached at 110 DEG  C. with 30-38% HCl.  The temperature and pressure of crystallization are controlled to permit selective crystallization of FeCl2 (see Fig. 3, not shown), which may be recrystallized. The liquor containing the other chlorides may then be crystallized under different conditions to give e.g. AlCl3 crystals. The FeCl2 crystals are dehydrated in a counter-current of H2 + HCl at 300-450 DEG  C. and reduced (see Fig. 7, not shown) at 575-675 DEG C., e.g. in H2 given off in the leaching process, thus generating a mixture of H29HCl, which may be used in the dehydration, or the HCl may be absorbed in water and recycled, and the H2 used in the reduction.  The product iron is cooled in H2 or inert gas, scrubbed with water to remove soluble chlorides, and dried. The process may be operated continuously.  The mother liquor from both FeCl2 and AlCl3 crystallizations may be hydrolysed in a fluidized bed, with air and natural gas (see Fig. 4, not shown), to give oxides of the other metal chlorides present.  These oxides, e.g. Al, Ca, Mg, may be used as pigments, or reduced to metallic form.
