Title: Improved drill testing and/or drilling machine
IPC: B23B47/18
Filed: 1938-07-07
Abstract: 506,971. Drilling and drill-testing machines. KENYON, A. S. G. July 7, 1938, Nos. 20077 and 35645. [Class 83 (iii)] In a drilling or drill-testing machine the drill is rotatably mounted in a fixed head and the work table is fed resiliently towards the drill, clamping means being provided for preventing undue movement of the table when the drill breaks through the work. The machine oomprises a fixed head I supported by four columns 2 and carrying a spindle 15 for the drill 17 which is rotated by gearing 16 and belt 14, from an external source of power. The work table 6 has brackets at the comers carrying ball-bearing rollers 10 which engage guide surfaces 11 on the columns and is fed upwards by two or more sets of pulley blocks and cables 3, 5 and adjustable weights 4. A damping force is applied to the table by one or more dashpots 18 attached to the columns 2 having piston rods 19 connected to brackets on the table, the damping force being arranged so that it does not impede the feed but comes into action when the drill breaks through. The rate of feed before cutting commences may be adjusted by connecting opposite ends of the dashpot by pipes 20 and connecting the several systems in parallel by pipes 20a, an adjustable valve 21 being placed in one of the pipes 20 to vary the speed at which the liquid may pass from one end to the other of the dashpots. The system is kept full of liquid by a reservoir 20b. The work table is returned by means of a screwed sleeve 25 connected thereto by a thrust bearing and splined to a shaft 25a driven by bevel and belt gearing 26, 28 from the external source of power, a nut segment 22 for engaging the sleeve being mounted on a fixed support 23 and being movable into and out of contact with the sleeve by a hand-operated screw 31. The movement of the table is also controlled during drilling by rods 33 pinned at 36, Fig. 2, to the under side of the table and carrying at their lower screwed ends adjustable sleeves 40 on which are freely slidable sleeves 39 screwed into cylinders 32a slidable on the rods. Springs 37 are compressed between flanges 38 on the cylinders and the ends of the sleeves 39. The cylinders are supported by the springs 37 resting on the upper ends of the sleeves 40 and the latter are adjusted on the rods 33 so that the upper ends of the cylinders will come into contact with the lower side of the fixed support 23 when the drill commences to break through the work whereby the springs 37 are further compressed by the sleeves 40 to keep the load on the table constant. When the drill has broken through, adjustable rings or lock-nuts 41 on the sleeves 40 engage flanges 39a on the sleeves 39 to prevent further movement of tho table. The compression of the springs 37 is adjusted initially by the sleeves 39 so as to be equal to the feeding pressure applied to the table by the weights.

Abstract: 1,102,203. Straightening. VOSS ENGINEERING CO. 13 May, 1965 [23 June, 1964], No. 20183/65. Heading B3E. A roller leveller includes four vertical corner posts, a top frame and a bottom frame supported by the posts, a top set of rolls and a bottom set of rolls supported by the top and bottom frames, respectively, means between the top frame and top set of rolls to effect vertical adjustment of the top set of rolls, the top frame being rectangular, and four separate jack means, each for lifting and lowering one corner of the top frame relative to a corner post to unclamp or clamp, respectively, the top frame relative to the four corner posts. An upper set of leveller rolls 22 is backed by backup rolls 24 on a support 38 backed by wedges 35, 54 on a rectangular frame 20 supported on four corner posts (80), Fig. 15 (not shown). A lower set of leveller rolls 23 is backed by rolls 24 on a support 37 backed by wedges 35, 34 on a rectangular frame 21. The frame 21 is formed with arcuate lower surfaces at its sides which are supported in arcuate surfaces of saddles (200), Fig. 18 (not shown). The saddles (200) are, further, supported on wedges (103). The top plate 20 is clamped on and lifted off the parts (80) at each corner by worm and screw means (75), Fig. 15 (not shown), each driven by a separate motor (73). Adjustment of the upper rolls 22 relative to the top plate 20 is effected by movement of wedges 35 by rotation of threaded shafts 243 or by movement of wedges 54 by a motor (45), Fig. 9 (not shown). The wedges 54 at the centre of the rolls are tapered more than those at the ends to bend the rolls into concave or convex shape, thus increasing pressure on the ends or centre of sheet being levelled. Adjustment of the lower rolls 23 relative to the bottom plate 21 is effected by movement of wedges 35 by rotation of threaded shafts 242 or by movement of wedges 34 by individual motors 31. The bottom frame 21 is tilted along the saddles (200) about a centre bottom leveller roll as centre by motor-driven eccentrics (67) (Fig. 13, not shown), thus bringing the upper and lower rolls closer at the outer entrance to the machine. Each saddle (200) is independently vertically adjustable by a motor-driven wedge (103), Fig. 18 (not shown). Stop means control various adjustments.

Patent GB-775114-A (GB)
Title: Improvements in or relating to the production of phosphate-containing fertilizers
IPC: C05B19/00
Filed: 1954-07-14
Abstract: Phosphate fertilizer in the form of pellets or powder is produced in a single stage operation by forming an aqueous slurry of the ferilizer constituents in the desired proportions and injecting the slurry under <PICT:0775114/III/1> pressure into a rotary drier heated with a concurrent flow of hot gas to form the desired pellets or powder.  The resulting pellets or powder are sifted to separate those particles that are larger than the desired size such separated particles being crushed and recycled to the rotary drier separately from the injected slurry, together with any particles that are smaller than the desired size.  The slurry may be injected under a pressure of 2 kg/cm2 and the turbulence of the injected spray may be increased by placing helical fins in the spraying tube.  The initial slurry may consist either of a paste of simple or triple superphosphate resulting from the action of sulphuric or phosphoric acid on a phosphate or of a slurry obtained by mixing water with a simple or triple superphosphate prepared elsewhere. In either case nitrogenated or potassium fertilizers such as ammonium sulphate or nitrate, or potassium sulphate or chloride may be added.  As shown in the drawing a slurry is formed in a vessel 1 provided with an agitator 2 and passed by pump 4 through line 3 to a rotary drier 6 through an injection nozzle 5, under pressure of 2 kg/cm2.  The drying cylinder is provided with helical fins to agitate the material as the drier rotates and is heated by combustion gases from a fire box 7 which enter at a temperature below 900 DEG C.  The products leave the drier and pass through a sifting mechanism made up of screens 8, 8a and 8b whereby the larger pieces are collected at 11 and after passing through a crusher 9 are recycled through line 10 to the rotary drier.  The product size granules of 2-4 mm size are drawn off at 12 whilst fine particles of 1.5-2 mm size are drawn off at 10 for recycling to the drier.  A small proportion of particles of 0-1 mm size are withdrawn at 13.  According to an example (1) crushed Gafsa phosphate was mixed with 30 per cent phosphoric acid in the ratio of 1 part of P2O5 in the phosphate for every 2.9 parts of P2O5 in the acid.  The mixture obtained was injected at a temperature of 55 DEG C. into the drier 6 fed with gases at 550 DEG C. and at the same time twice the quantity of recycled fines were fed hrough line 10.  The product had a 6 per cent moisture content.
