Abstract: 412,617. Pistons. LUCAS, Ltd., J., and PITT, H. W., Great King Street, Birming- ham. Dec. 31, 1932, No. 37051. [Class 122 (i).] A vehicle shock-absorber of the fluid-controlled piston-and-cylinder type comprises a hollow piston c having an axial bore i equal in diameter to that of the piston-rod d, a dummy-rod k supported within the cylinder a and extending into the bore i, and a passage in the rod d along which oil &c. accumulated in the bore i can be displaced when relative movement occurs between the piston and cylinder. The piston-rod d extends into a reciprocating chamber b and is connected through a lever e with a spindle f to which the usual operating arm g is secured. The rod k may be supported from the end of the cylinder by means of resilient spring-pieces l. On movement of the piston to the left, fluid is forced past a screw-adjustable valve rand through a byepassage o to the other side of the piston, while on movement to the right, fluid flows from one side of the piston to the other past a non-return valve q in the piston. During the latter movement any oil &c. which has leaked into the piston past the dummy rod is displaced along the piston rod and past a non-return valve or breathing-hole j in the end of the rod, into the chamber b. This fluid is replaced by fluid drawn from the chamber b into the cylinder a through a passage in the chamber wall, a slot u in the aperture containing the valve r, and the byepass o.

Title: Improved iron ore pellet and process and apparatus for the production thereof
IPC: C22B1/24
Filed: 1962-10-02
Abstract: <PICT:1011594/C1/1> A self-fluxing pellet is produced by kilning a pellet comprising a core of iron ore and flux material, e.g. compounds of Ca or Mg, surrounded by a flux-free iron ore coating. In Fig. 6, a mixture of flux (32%) and iron ore (68%) in hopper 1, ground to - 14 U.S. mesh, is funnelled on to conveyer 2 and delivered to drum 3 where it is sprayed with water and forms into balls which roll down the rotating drum.  Screening device 5 delivers cores of diameter 3/8 inch, via conveyer 6, to drum 10. Iron ore from 11, and water, are introduced along the length of the drum and the resulting ore-coated pellets are screened at 17 to deliver pellets of diameter 1/2 -inch to furnace 20.  A gas permeable conveyer 21 carries pellets through drying zone 24 (at 500 DEG  F.), burning zone 25 (at 2200-2400 DEG  F.) and cooling zone 26.  Cool air from wind-box 31 passes up through 26 to conduit 35.  This preheated air supports combustion of fuel introduced into 25 through nozzle 40 and also flows through conduit 37 to zone 24. These gases are drawn into suction box 30 and exhausted at 42.  In a preferred embodiment, furnace 20 is replaced by furnace 70, illustrated in Fig. 7.  Hood structure 72 and baffles 73 define three zones:  74 for preliminary drying, 75 for final drying at 500-900 DEG  F., and 76 for preburning at 1600-1800 DEG  F., while rotary kiln 77 defines final burning zone 78, at 2200-2400 DEG  F. Pellets are carried on conveyer 81 at such a rate that in 75 water vapour escapes through, but does not crack, their coating, and in 76 any magnetite in the ore is converted to haematite and bridging of grains of haematite is initiated in the coating. Pellets are then tumbled in 78, where a continuous network of haematite is produced and the coating is densified and confines any liquid slag formed; and are finally cooled in an upward-flowing air stream in 83.  This preheated air enters firing hood 86 of kiln 77 having burner 90, and hot gases proceed through 78, downward through 76 to suction box 91 and conduit 92, downward through 75 to conduit 94 and wind-box 95, upwards through 74, and are exhausted at 96. Ca and Mg ferrites are shown to be present in the core. Specification 835,981 is referred to.

Abstract: 374,838. Coking and carbonizing processes ; rotary retorts. MEIER, A. J., Kirkwood, Missouri, U.S.A. Dec. 12, 1930, No. 37551. [Class 55 (i).] The gases evolved during the distillation of carbonaceous materials in a rotary retort are superheated and the distilled material allowed to pile up in a heap, the superheated gases then being forced through the heap before passing through the agitated material. Coal is fed to an inclined rotary retort 6 from a hopper 1 and conveyers 3, and after distillation piles up in a container 9. The gases are taken off through an off-take 13 and pass to storage 21 after passing through heat exchangers 15, 16 and a bye-product recovery plant 18. The storage 21 supplies gas to off-takes 20, 22, 35 respectively ; the first feeds gas to burners 25, 25a in hot stoves 29, 31, after preheating in the heat exchangers 15, 16; the second supplies gas for outside consumption ; the last supplies gas to be superheated in the hot stoves, after being preheated in conveyers 11 through which hot coke is ejected, and prior to injection through the retort through pipe 55. Secondary air is supplied to the burners 25, 25a through pipe 27 after traversing the heat exchangers. The hot stoves are alternately heated and cooled, and the gas to be superheated is delivered to that stove in which combustion is not taking place at that particular time. The temperature of the superheated gases is controlled by a valve 39 and thermostat 44. During the heating up of the stoves the combustion products are taken off through a pipe 32 to preheat coal in the conveyers 3 before admission to the retort. The retort may be water cooled and cold water may be supplied to the jacket from an adjacent rotating water wheel. Water from the hub 66, Fig. 5, passes through radial tubes 67 on release of valves 68 within the tubes, to inlets 63 in the periphery of the jacket. A valve 68 is released when a nozzle fixed to the valve is forced inwards by impact with a valve 64 in an inlet 63. A similar arrangement for receiving heated water from the jacket is provided.

Title: Electrical Control Method and Apparatus
IPC: B03C3/66

Abstract: 1,154,972. Control systems for electrostatic precipitators. JOY M.F.G. CO. 23 Aug., 1966 [30 Sept., 1965], No. 37685/66. Heading H2H. A control system for an electrostatic precipitator comprises means whereby the average discharge electrode voltage is maintained at a maximum value. The precipitator 10, 12 is supplied from an A.C. source 13 by way of a step-up transformer 14 and rectifier 18, the voltage across the precipitator electrodes being controlled by way of a saturable reactor 22 serially connected between the A.C. source and the primary winding of the transformer 14. A signal proportional to the voltage across the precipitator electrodes is fed to a transformer 32, 33 and is then rectified to give a steady D.C. signal by a rectifier and filter 34. The output of the rectifier 34 is fed to a dual time constant unit 36 having a short time constant whilst the precipitator voltage is rising and a long time constant whilst the voltage is falling and the output voltage of this unit 36 is fed to a polarized differentiating unit 38. The unit 38 is constructed to produce a D.C. output signal only when the precipitator voltage is falling and this signal is proportional to the rate of decrease of the precipitator voltage. The output voltage of the unit 38, after amplification, controls a trigger circuit 42 which produces a single output pulse each time it is energized from the unit 38. The pulses are amplified and used to control a "flip-flop" unit 48 whereby alternate output signals of opposite magnitudes are produced. These signals control a scan generator 52 whereby alternately rising and falling D.C. outputs are derived having a slow rate of rise or fall. The output of the generator 52, suitably limited and amplified, is used to feed the control winding 24 of the saturable reactor 22 and thus to control the voltage applied to the precipitator electrodes 10, 12. Thus, should the precipitator voltage tend to fall along a curve 66 on either side of a maximum value 68, the reactor 22 will receive a signal to return the voltage to the value 68. A time delay unit 50 may be provided to prevent false operation of the control circuit and a filter unit 73 provided to isolate the units before the filter from those after the filter. Furthermore a switch may be incorporated in the control circuit so as to enable manual control of the precipitator voltage to be made. The saturable reactor may be replaced by a thyristor.

A device for maintaining a belt central on its supporting idlers 12, 13, 14 comprises a bracket 10 having a plate 11 arranged transversely of the direction X of belt travel carrying bearings (not shown) for the spindles of the rollers. The bracket 10 has a stiffening rib 15 which rests on part of the conveyer frame 18 and is further supported by a horizontal pivot pin 16 resting in a U-slot in a support 20 fixed to the frame 18, the slot being 10% larger than the pin 16. A vertical pivot pin 17 attached to the rib 15 rests in an aperture 19 in the frame 18, the aperture 19 being 12¢% larger than the pin 17. This mounting permits the bracket 10 limited angular movement about axes parallel to and perpendicular to the direction of belt travel. When the belt wanders off-centre the forces acting on the bracket cause it to tilt towards the side to which the belt is moving and forward on that side introducing a centralizing force on the belt.
