Title: Ore reduction methods and apparatus
IPC: C21B13/08
Filed: 1961-12-05
Abstract: 927,342. Reduction of iron oxides. R-N CORPORATION. Dec. 5, 1961 [Dec. 6, 1960], No. 43571/61. Class 72. A process for the direct reduction of iron oxide material comprises charring coal to provide a low volatile coke char with evolution of gases, mixing iron oxide material and the char, and reducing the oxides in a furnace without fusion, the evolved gases being burned with a controlled amount of oxygen to produce heat for the reduction. As shown, coal of size passing # inch mesh is delivered to a bin 35 from the bottom of which it is delivered to a fluidized feeder 41 wherein it is dried and preheated to 160‹ F. by gases. The dried coal then passes to a fluidized bed pretreater 44 where it is heated under oxidizing conditions and then flows to a fluidized bed coker 65 where the bed is maintained at 1550‹ F. and the volatile content of the coal reduced to 5%. The coke then passes to one of a series of bins 23-26, provided for the storage of iron oxide, limestone, fresh coke and recycle coke, from which it is fed with iron oxide and limestone to a rotary furnace 1, the gas from the coker being conveyed to a burner 22 at the other end of the furnace. Excess coke from the furnace discharge may be recycled to the bins 23-26. A moving grate coker may replace the fluidized bed coker. Specifications 803,008 and 882,324 are referred to.
Patent GB-1481180-A (GB)
Title: Tyre identifying apparatus
IPC: G06V10/20
Filed: 1974-10-09
Abstract: 1481180 Character recognition systems YOKOHAMA RUBBER CO Ltd 9 Oct 1974 [9 Oct 1973] 43820/74 Heading G4R An apparatus for scanning and recognizing a mark, such as a group of alphanumeric characters, on the side of a tyre includes mechanism for positioning the tyre before a scanning system and for causing relative rotation between the scanner and the tyre so that the mark appears in the field of view of the scanner, the scanner output feeding a recognition unit. Circuitry is provided for eliminating the effects of slowlyvarying amplitude changes in the scanner output. The tyre moves along a roller conveyer and its internal diameter is determined by known means. In one arrangement, Fig. 2, when the tyre 1 reaches the scanning position it is centred on a platform 5 by arms 7. The platform is raised to the required distance below scanner 11, as determined by a photocell 9 or switch or by the previously measured width of the tyre. Scanner 11 and the light source are moved horizontally as determined by the tyre diameter to a position in which the mark will be viewed as the platform is rotated. After scanning the platform is lowered to return the tyre to the conveyer. Instead of rotating the tyre a prism and mirror arrangement may be rotated over the tyre to direct light via a dove prism to an axially-mounted scanner (Fig. 11, not shown). The mark on the tyre comprises an embossed alphanumeric group of characters which may be preceded by a start symbol. The characters are roughened relative to the background, or vice versa. The scanner output consists of a series of pulses whose amplitude represents character or background (black or white) together with a slowly varying distortion signal arising from the characteristics of the tyre surface. A circuit, Fig. 9, compares at 45 the amplitude B of the present pulse 52 with two values. If it exceeds the upper value pulse 52 is assumed to represent white, and if it is lower than the lower value it is assumed to represent black. If it lies between these values a signal #V 0  from generator 46 is added to or subtracted from B, dependent upon whether the preceding pulse S2, which had an amplitude A, represented white or black. The resulting signal B  #V 0  is compared at 50 with A. If it is less than A pulse S2 is assumed to represent white, and if it is not it represents black. The black/white pulses pass to a recognition unit for comparison with signals representing reference characters. Read-in to the recognition unit may be prevented until the start symbol has been detected.

Abstract: 1,080,488. Rolling. ALLMANNA SVENSKA ELEKTRISKA A.B. Nov. 3, 1964 [Nov. 4, 1963], No. 44711/64. Heading B3M. [Also in Divisions G3 and H2] A rolling mill having working rolls 11 and 12 driven by motors 13 and 14 includes means 15 and 16 for measuring the output torques of the motors, the measured torque values being fed, together with a speed reference signal 27 and signals from tachometers 30 and 31, to integrating amplifiers 23-26. The outputs from these amplifiers and from current regulating circuits 17 and 18 are fed to controllers 19 and 20 for regulating the load distribution of the motors 13 and 14 to a desired value. The measured values of torque are each fed both to an amplifier associated with its own motor control system and to an amplifier associated with the other motor system the inputs to the controllers 19 and 20 thus representing the actual load distribution between the motors. Alternatively, the measured signals can be combined to produce a value corresponding to total roll torque, the motors then being controlled to regulate the gradient of the curve of roll torque against speed of revolution. The control system can be applied to the motors of two successive stands of a continuous mill, one motor for each stand driving both the rolls.

Abstract: 1510350 Ink-recirculation apparatus INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1975 [23 Dec 1974] 45267/75 Headings B6C and B6P Liquid dispensing apparatus especially in an ink-jet printer, Figs. 1 and 2 (not shown) includes an outlet for a stream of liquid under pressure into a region open to atmosphere; a collector for liquid dispensed from the outlet but unused and a return flow conduit including a liquid trap and a pump, the trap being located between the collector and the pump to limit the entry of atmosphere to the amount required to replace liquid used and thus not collected for recirculation. In the system shown in Fig. 6, ink is supplied from bottle 100 through hoses 104a to 104g connecting bubble catchers 120, 122, pump 116, capillary 151 main valve 154, conduit 155 to ink-jet nozzle 125. Undeflected drops are collected in gutter 53 and pass through J-tube 115, hoses 113b and 113a back to bottle 100, which is rigid and sealed. Withdrawal of liquid from bottle 100 by pump 116 during printing creates a vacuum in the return conduit; depending on the level of liquid in J-tube 115, ink or air is drawn back into bottle 100. Thus whether ink or air is drawn back depends on the rates at which ink is being used or collected as represented by the level of ink in J-tube 115 in relation to servo point 115b. A reservoir 133 is associated with J-tube 115 to allow for overfilling of the tube, e.g. when the temperature of bottle 100 rises and prevents an effective vacuum being created in the return line.

In Fig. 1, the support means are provided by flanges, screws 12 securing the latches in position. Shock waves are produced by an explosive 17. Baffles 10 on the latches are struck by the shock waves and increase the clamping forces. In various modifications, Figs. 2-6 (not shown), the screws 12 may be replaced by keys (13, Fig. 2), the latches (9b, Fig. 3) may be pivoted on pins (20) located in the die or on members attached to a casing (7a, Fig. 4) for a concrete die. The latches may be adjustable by screw threads (Fig. 6), or formed in two parts (14, 15, Fig. 5) pivoted together at an angle which tends to straighten when the shock waves strike baffles (10a) on the latches. The latch-flange (11a) is adjustable and secured by screws (16). The die may be formed of ice.
