Title: Method and apparatus for making fine crystal abrasive alumina
IPC: C09K3/14
Filed: 1962-03-05
Abstract: Fine grain abrasive fused alumina is prepared by reducing bauxite with a carbonaceous reducing agent and depositing the molten reduced material containing from 94-100% alumina in a thin curved strip partially solidified by cooling, compressing the strip if desired, prior to charging the curvature of the strip whilst still plastic to fragmentize partially the same, further coding the strip to effect solidification and fragmentation of the strip, and finally crushing the fragmentized product. In the Figure alumina at 2000 DEG  C. is flowed from furnace 10 via spout 12 into graphite trough 14 whose forward side is open, and then in the form of a thin layer, e.g. 1/16 to 1/8 inch thick and 12 inches wide on to the upper curved surface of quenching cylinder 20 of diameter 24 inches rotating at 10-15 revs./min., whose surface is maintained below the melting point of the alumina, e.g. below 1350 DEG  C., by jets of water directed against the inner side of the cylinder from spray head 54. The alumina is then pressed between the surfaces of cylinder 20 and <PICT:0956178/C1/1> squeeze cylinder 24 of diameter 20 inches.  It then falls to conveyer 37, about 14 inches below the line of contact of the cylinders, moving at a speed of 90 feet per minute in a direction away from the downwardly moving surface of cylinder 20. Spray-heads 60 direct jets of water against the underside of the conveyer belt.  In a modification the molten alumina is deposited on the interior of the cylinder, doffed therefrom by rotation and spilled axially from one end by inclining the cylinder.  The final product has a crystal size of less than 1% monocrystalline in 24 grit and 4-14% monocrystalline in 80 grit, i.e. crystals of 1-30 microns.

Title: Predictive control process and system
IPC: G05B13/04
Filed: 1974-02-25
Abstract: 1442040 Automatic control SIEMENS AG 25 Feb 1974 [3 Oct 1973] 8528/74 Heading G3N A predictive control process for automatically controlling a system employs a model of the controlled system which is subjected to a succession of test operations. As shown, an n order actual value vector X is compared in a comparator 4 with a desired value vector W to produce a control error vector E having components Eo-En. These components via a switch 12 and a store 13 are fed to a controlled system model 14. The model 14 receives a control signal of value V 1 , V 2 , of different polarity, or zero, in dependence on the settings of switches 15a, 15b and produces a simulated control error vector e the components of which are squared in a device 16 and summated by a device 17. The maximum value of error vector e is detected by a differentiating device 19 and limit signalling means 20 which together provide an output signal as long as the error vector does not vary, indicating a maximum value. The first pulse from device 20, after the application of a signal V 1 , V 2 , actuates a stepping controller 23 to apply the output of device 17 to a store 24, or 25. The contents of stores 24, 25 are compared in a comparator 22 and modify the stepping sequence of the controller 23. The stepping of the controller 23 is also effected by selected output signals from stages S1-S16 through an OR-gate 44 by a pulse-generator 26. The controller 23 selectively operates switches, as shown. On completion of a predictive cycle, the controller actuates a switch 2a or 2b to apply a control value V 1 , V 2  to the controlled system.

Title: Packing for piston rods
IPC: F16J15/28
Filed: 1933-03-21
Abstract: 416,731. Stuffing - box packing. JONES, G. F., 10, Langbourne Avenue, West Hill, Highgate, London. March 21, 1933, No. 8549. [Class 122 (v).] In a packing of the kind comprising two segmental rings 2, 3 encircled by several concentric flat section springs 1, the innermost spring is provided with projections 4, 5 engaging the ends of two adjacent segments in each ring thereby holding the joints of the rings in spaced relationship. The projections may be provided by the inturned ends of the stepped split in the ring. The pressure of the packing on the rod can be adjusted by so positioning the gaps in the various springs that friction between the contacting surfaces of the springs opposes the fluid pressure acting radially on the ring to the desired extent. In a box provided with a number of recesses containing packing rings the pressure of the various rings is equalized by reducing the number of springs in proportion to the fall of pressure along the box.

Title: Internal combustion engine
IPC: F02B51/02
Filed: 1973-02-22
Abstract: 1426912 1C engine NISSAN MOTOR CO Ltd 22 Feb 1973 [3 April 1972 21 April 1972 28 June 1972 4 July 1972 13 Sept 1972]  8685/73 Heading F1B Fuel and hydrogen peroxide are supplied to the combustion chamber 23, the hydrogen peroxide being enothermically decomposed to water vapour and oxygen and causing combustion of the fuel. In the embodiment shown hydrogen gas, petrol or kerosene is fed by a pump 36 to an injector 29 to open a valve (55), Fig. 2 (not shown), therein which controls the flow of fuel and hydrogen peroxide gas through a divergent nozzle (52). The flow of fuel through the nozzle induces the flow of hydrogen peroxide. Exhaust gases are recirculated to the engine intake by an engine driven pump 39 and the flow of exhaust gases are regulated by a throttle valve 45. The fuel pump 36 and the exhaust discharge control valve 43 are controlled in accordance with the suction in a Venturi 46 in the exhaust gas recirculation passage 44. The exhaust gas recirculation may be replaced by the supply of air or water to the combustion chamber.23. A Wankel engine, Figs. 3 and 5 (not shown), is supplied with hydrogen peroxide through a pair of injectors (64) both receiving fuel and hydrogen supplied by respective pumps (67, 70). The injectors (64) include hydrogen peroxide and fuel check-valves (88 and 99) and in the hydrogen peroxide flow-path within the injector a catalyst (97), e.g. a silver based material, causes decomposition and a swirler (96) is located downstream of the catalyst. Fuel may be supplied to a Venturi (75) in the exhaust gas recirculation passage (73). An exhaust gas reservoir (74) in the recirculation passage may have an exhaust gas release valve (78) and an air intake valve (102) which open above and below respectively certain pressures in the reservoir. Fuel in the form of a rod (152), Fig. 8 (not shown), of plastics material may have one end in the combustion chamber opposite the outlet of the hydrogen peroxide injector (142). The opposite end of the plastics rod (152) is subjected to the pressure in the exhaust gas discharge passage 42 upstream of a discharge valve (141). An engine, Figs 14 and 15 (not shown), may be operated alternatively with supply of hydrogen peroxide and exhaust gas recirculation or air intake and no exhaust gas recirculation. Valves (212, 208 and 219) control the flow of exhaust gas, fuel, and air and exhaust gas for the two alternative modes of operation. The engine may be operated with limited exhaust gas recirculation in the air intake mode of operation, Fig, 16 (not shown). Operation with hydrogen peroxide may occur below a predetermined engine or vehicle speed or in accordance with engine speed, the suction in the exhaust gas recirculation passage, the position of the recirculation control valve and the temperature of the recirculated exhaust gases or of the cooling medium of the engine.

The furnace may be of the channel type in which the additive(s) are mixed in the channel(s) of the inductor(s) or the furnace may be of the crucible type in which the additives are supplied to the melt from above, optionally by injection with a gas stream which may contain oxygen, or from below the melt or from the sides of the melt. The reducing agent and/or oxygen and/or an inert gas (e.g. argon) may be introduced into the melt via porous plugs in the furnace or may be introduced together with ore concentrate via nozzles in the walls or bottom of the furnace. Stirring of the melt may be obtained by the injection of the gas stream from above, by the purging action of the gases introduced through the porous plugs and nozzles and by inductive stirring. Excess reducing agent may be provided to act as a source of heat in the reduction process and oxygen may be supplied separately to the melt through cooled tubes or nozzles in the furnace. A slag may be present on the surface of the melt the viscosity of the slag being controlled by lime and fluorspar additions and by the supply of reducing agent and oxygen to the surface of the melt. Carbon monoxide and hydrogen produced in the process may be burnt to produce electrical energy to supply the induction furnace.
