Filed: 1965-01-28
Abstract: 1,099,982. Curving. HITACHI ZOSEN KABUSHIKI KAISHA. Jan. 28, 1965 [Feb. 15, 1964; Feb. 22, 1964], No. 3784/65. Heading B3E. Roll apparatus for curving metal plate comprises an upper and a lower workpiece delivery roll, rotating in opposite directions and a rear bending roll raised or lowered in a direction at an angle to a line transversely through the longitudinal axes of the delivery rolls, the drive for the elevation or lowering of the bending roll being started by control means including a group of switches which are adjustable and successively actuated during delivery of a workpiece and a control means including switches being provided for stopping the elevating or lowering of the bending roll. A plate 3 to be curved is first held at its tip by rollers 1, 2, a front bending roller 6 is then raised by means 31, 32 driven from a motor 30 through a driving shaft 34, which shaft 34 also moves a cam member 38 between switches 37 and 36. The rise of the roller 6 is stopped by engagement of the switch 36 by the cam 38 which also starts rotation of rollers 1, 2 which is stopped when projection 40b attached to the plate 3 engages a switch 40a. The roller 6 is then lowered until stopped by actuation of switch 37. The rollers 1, 2 are then restarted and a clutch 25 engaged to drive a cam 23 along a shaft 24, the resultant actuation of the switch 17 causing a motor 9 to drive, through a stepless change-speed gear and shaft 11, means 7, 8 to raise the rear roller 5. The rise of the roller 5 is stopped by actuation of a switch 13 by a cam 15 moved along a threaded part 12 of the shaft 11. Actuation of a switch 19 by the cam 23 then reverses the motor 9 to lower the roller 5, actuation of the switch 14 stopping such descent. Actuation of a switch 18 causes the roller 5 to rise again, this rise being stopped by the switch 13 and actuation of the cam 20 causes the roller 5 to descend, its descent being stopped by the switch 14. The cam 23 then actuates a switch (not shown) to stop the rolls 1, 2 and the cam 23 is returned to its starting plane by disengaging the clutch 25 and engaging the clutch 26 to a drive source 28. In another embodiment, Fig. 4, means to control the movement of the bending roller 5 and drive of the rollers 1, 2 includes cams 43-46 on a shaft 42, driven through a stepless change-speed gear 69 from the drive to the roller 2, engaging switches 47-50, each adjustable by a hand operated bevel gear 51-54. Switches 63-66 at the ends of the roller 5 serve to stop the rise of the roll 5 and start rotation of the rolls 1, 2.

Title: Improved hard-burned iron ore agglomerates and method for the production thereof
IPC: C22B1/24
Filed: 1964-01-30
Abstract: <PICT:1009966/C1/1> In a process for preparing hard-burned aggregates from magnetite or haematite ores, or iron ore in which both are present, and associated gangue materials, the ore is mixed with flux to provide a basic reagent for slagging the acidic components of the gangue, the mixture is formed into agglomerates, the agglomerates are heated in an oxidizing atmosphere to a pre-burning temperature at which magnetite if present will be converted to haematite and below that at which liquid slag will form, until a substantial number of adjacent granules of haematite bridge together, and the agglomerates are burned at a temperature at which a liquid slag is formed and held within the network of bridged haematite grains.  As shown, ore and flux from hopper 1 are delivered via conveyer 2 to balling drum 3 wherein the mixture is sprayed with water via pipe 4.  Agglomerates from drum 3 are screened by device 5 to desired size, e.g. half-inch diameter, undersized agglomerates being recycled by conveyer 7. The desired agglomerates are conveyed to travelling grate 11 in furnace 10, through zones 14, wherein they are dried and pre-burned at between 1800 DEG  and 2200 DEG  C., 15 wherein they are burned at slagging temperature, to cooling zone 16.  Cooling air entering 16 via 22 is passed to zones 14 and 15 via conduit 23 and thence via opening 27 to exhaust conduit 28.  Sufficiency of pre-burning is indicated by continuing until all CO2 has been evolved, or by inspection of a micro-photograph of the agglomerate, or by testing a sample by tumbling the agglomerates, e.g. in a rotary drum.  In a second embodiment which applies the process described in Specification 835,981, the agglomerates are tumbled during burning at slagging temperature, whereby the agglomerates acquire a densified shell of bridged haematite grains.

IPC: F04B39/00
Filed: 1920-02-10
Abstract: 162,817. Young, A. E. Feb. 10, 1920. Compound p i s t o n pumps; pump-actuating mechanism.-In a twostage compressor in which the stages are of substantially equal volume, gas is admitted to the second stage by the motion of a pin and sliding block which transmit power from the crank. In the apparatus shown, the first and second stage pistons a, b are rigidly connected, and are actuated from a crankshaft through a block e sliding in contact with surfaces on the pistons or on parts connected to them. In the first stage, gas or vapour is drawn in at a valve g and forced through a valve h in the piston and passages opening at ports i into a receiver space between the axially aligned cylinders. The motion of the sliding block e uncovers at intervals a passage f through the piston b whereby the gas from the receiver passes to the second stage compression cylinder above the piston. Where, as in refrigerating plants, gases at two different pressures are to be withdrawn simultaneously, the gas at higher pressure may be led into the receiver space at the port m.
