Filed: 1934-09-17
Abstract: 429,149. Drilling-machines. VOMAGBETRIEBS AKT.-GES., Plauen, Vogtland, Germany. Sept. 17, 1934, No. 26658. Convention date, July 31. [Class 83 (iii)] In a drilling-machine having one or more vertically arranged stationary spindles and a hydraulic vertically-fed work-table, the control valve for the table is operated by a handle arranged near the spindle so that vertical movement of the handle operates the valve and lateral movement operates the switch of the motor which drives the spindles. The machine comprises a frame 1 carrying a vertically fed table 12 and a plate 9 to which are attached the bearings 8 for a number of drill spindles 5 which are adjusted laterally by screwed shafts 10 and nuts on the bearings 8. The pulleys 6 on the spindles are all rotated by a belt 4 passing over guide pulleys and driven by a motor 2 within the frame 1. The table 12 has a vertical extension 14, Fig. 1, at one side which carries lower and upper bearings 15, 16, engaging opposite sides of a vertical guide-rod 17 secured to the frame. Rotation of the table about the rod is prevented by a shoulder attached to a bracket on the table and held by spring pressure against a guide-strip 20. The table is fed by a hydraulic cylinder 21, Fig. 3, pivotally supported at 27 on the frame and provided with a piston rod 23 connected to a pivot 24 on the table. Oil is supplied to the cylinder by pipes 30, 31 and a pump 28 driven by a motor 29. The reversing and control valve for the cylinder is operated by a U-shaped handle 32, Figs. 1 and 3, passing round the front of the machine adjacent the spindles 5 and arranged so that oscillation of the handle about the axis of a shaft 33 operates the valve whilst axial motion of the shaft operates the switch 36 for controlling the motor 2. The valve, (not shown), has five positions, the upper and lower extreme positions of the handle 32 causing rapid downward and upward movement of the table, the intermediate lower position causing a slow upward feed, the intermediate upper position opening the bottom of the cylinder to exhaust so that the table may descend by its own weight, and the horizontal centre position shutting off both ends of the cylinder to maintain the table stationary. The handle 32 may also be operated automatically through bevel gears connecting its shaft 33 to a vertical shaft 37, Fig. 1, collars 40 being adjustably secured to the shaft 37 and being provided with cam grooves 41 engaged by a roller 39 on the table so as to rotate the shaft 37 at different parts of the stroke of the table. The pump 28 also supplies oil to a distributing device 43 and thence to the ball bearings of the spindles 5 by pipes 42.

Title: Improvements in or relating to processes of treating oxidized ores
IPC: C22B1/08
Filed: 1932-09-26
Abstract: Oxidized ores containing "reagent metal" are heated to 300-750 DEG C. in a reducing atmosphere containing a combustible reducing agent and sulphur dioxide, then cooled with exclusion of free oyxgen and preferably also of moisture to obtain "reagent metal" compound in an active condition and finally treated with an acidic reagent gas or gases, such as chlorine, hydrochloric acid, ferric chloride, or sulphur dioxide.  Alternatively, active "reagent metal" compound may be separately prepared and added to the ore.  "Reagent metals" are those capable of exhibiting more than one valency and include nickel, cobalt, copper, and manganese, though iron is the preferred reagent since a highly active magnetic oxide results from the reducing treatment described above which enables the desired metal values to be separated magnetically from the gangue.  The reducing agent may be producer gas, natural gas, hydrogen, or coal, and when a sulphurbearing coal is used it may supply the sulphur dioxide necessary.  Less than 1 per cent of sulphur dioxide in the reducing atmosphere suffices, but amounts up to 75 per cent may be p  used. In one example, a Cuban iron ore containing chromium and nickel is reduced with natural gas or finely divided coal in the presence of sulphur dioxide at 600 DEG  C., rendered "quasi-wet" after cooling, treated with chlorine and roasted at a low temperature to chloridize the nickel; or the cooled reduced ore may be treated dry with chlorine at 300 DEG  C.  After leaching to remove nickel, the residue may be treated to obtain a chromium concentrate and leave a tailing rich in iron oxide.  In another example a roasted copper ore containing iron is reduced with coal in the presence of sulphur dioxide, made "quasi-wet" after cooling, and treated with chlorine. Leaching the chlorinated product removes substantially all the copper.  In a third example, a roasted sulphide ore containing copper and nickel and some residual sulphide is reduced with coal at 600 DEG C., made "quasi-wet" after cooling, and treated with chlorine.  The amount of water-soluble copper and nickel is increased by providing additional sulphur dioxide during the reducing step. The treatment of an oxidized iron ore containing phosphorus and manganese is also referred to.  In each case details are given of the results when reduction is effected without adding sulphur dioxide.

Abstract: 1453712 Expandable grippers ARTHUR GUINNESS SON & CO (DUBLIN) Ltd 5 June 1974 [5 June 1973] 26684/73 Heading B8H [Also in Division F2] Apparatus for use in transporting and stacking kegs or pipes comprises a mounting block 4 on a support frame 5, a thrust block 2 which is displaceable relative to the mounting block 4 by an actuator (not shown), a plurality of loadengaging arms 14 (only one shown) extending from a respective pivotal connection on the mounting block 4 downwardly, each arm 14 having a load-engaging pad which is connected to the thrust block 2 by a respective link 8, each of which is length variable and comprises two end caps (8a, 8b) which are relatively movable, Fig. 3 (not shown) with a compression spring 10 located therebetween. In the absence of a load, when the thrust block 2 is in its position shown in phantom in Fig. 1, the pads 6 at the ends of the arms 14 are spaced at a first distance from each other and as the thrust block is moved downwardly through an intermediate position thereof the arms 14 pivot outwardly and the pads 6 attain a position in which the distance therebetween is a maximum. In operation, the pads 6 are located within an area defined by a rim 16 of a keg to be handled and spaced away from the rim 16, and the thrust block 2 is then moved downwardly thereby causing outward movement of the pads 6 towards the position in which spacing therebetween is a maximum, but before reaching that position they engage the keg rim 16 as shown, and further downward movement of the thrust block 2 causes contraction of the links 8 against the action of their respective springs 10 as the links 8 each pass through (a), their dead-centre condition, and when the thrust block 2 reaches a final position in which it engages the top of the keg the links 8 partially expand because they have passed through their dead-centre condition, but they maintain the pads 6 in contact with the keg rim 16, because they are still in a state of compression. The apparatus can be attached to any mobile lifting device such as a fork-lift truck or a crane.
