Abstract: This invention relates to a combustion control apparatus for a powdered coal-fired furnace that monitors noxious substances contained in burning waste gases, unburned substances in ash and power data of a pulverizing mill in order to operate the combustion furnace safely and efficiently. The combustion control apparatus infers from the current states optimal control amounts― that will keep in the minimum allowable ranges the noxious nitrogen oxides and the in-ash unburned substances that affect the combustion efficiency―and thereby controls the combustion furnace with good stability. 
     The combustion control apparatus qualitatively evaluates as fuzzy quantities the density data of nitrogen oxides contained in exhaust gases and of unburned substances in the ash and power data of the pulverizing mill. Based on the evaluation result, a fuzzy inference is formed to determine the optimum control amount of two-stage combustion air ratio for minimizing the nitrogen oxides and also the optimum control amount for a fine/coarse grain separator to extract powdered coal of a grain size most effective for minimizing the unburned substances in the ash.

Abstract: A method of selectively etching a body (18) of a semiconductor material, such as single crystalline silicon, having regions (20,22) of n-type and p-type conductivity to remove at least a portion of the n-type region. The body is placed in an etching solution of an etchant (14) having a high pH value and a positive voltage is applied between the body and the etchant. This forms passivating layers on the surfaces of the two regions with the passivating layer on the n-type region being different from that on the p-type region. The voltage is then removed and the body is etched for a period long enough to remove all of the passivating layer from the n-type region and at least a portion of the n-type region, but is not long enough to remove all of the passivating layer from the p-type region. This is allowed by the difference between the passivating layers on the two regions. The steps of forming the passivating layers and etching them is repeated until a desired amount of the n-type region is removed.

Abstract: A multiplying digital-to-analogue converter is of the kind in which digitally weighted currents proportional to a voltage applied to an analogue input (19) are generated at respective outputs (3) of a current mirror arrangement (1), these currents being switched to an output (9) in accordance with the value of a digital signal applied to a digital input (11). In order that the converter can accommodate analogue input voltage of either polarity relative to ground and generate corresponding output currents a bias current is applied to the current mirror input (2) from a current source (15). This results in digitally weighted bias currents being generated at the current mirror outputs (3). These bias currents are offset by corresponding bias currents generated at respective outputs (6) of a second current mirror arrangement (4).

Abstract: A method and apparatus for enabling analysis of a flowable material enclosed in a transport system having an infrared transparent wall portion. A temperature differential is transiently generated between a thin surface layer portion of the material and a lower or deeper portion of the material sufficient to alter the thermal infrared emission spectrum of the material from the black-body thermal infrared emission spectrum of the material, and the altered thermal infrared emission spectrum is detected through the infrared transparent portion of the transport system while the altered thermal infrared emission spectrum is sufficiently free of self-absorption by the material of emitted infrared radiation. The detection is effected prior to the temperature differential propagating into the lower or deeper portion of the material to an extent such that the altered thermal infrared emission spectrum is no longer sufficiently free of self-absorption by the material of emitted infrared radiation. By such detection, the detected altered thermal infrared emission spectrum is indicative of characteristics relating to molecular composition of the material.

Abstract: A refrigeration system (10), which conditions the air of a conditioned space (14) via heating and cooling cycles, includes a heat exchanger (42) and, in a first embodiment, heat pipes (58). A cryogen (18) is circulated through the heat exchanger during a cooling cycle. During a heating cycle the flow of cryogen is terminated and heat is transferred into the heat exchanger via the heat pipes. In another embodiment, the temperature of evaporation of a liquid cryogen in the heat exchanger is selected according to the desired temperature of the conditioned space, via selectable cryogen flow paths (232,238,244) which provide different pressures and thus different evaporation temperatures. Vaporized cryogen drives a motor (128) connected to a fan (130) which circulates air between the conditioned space and heat exchanger. In still another embodiment, the mass flow rate of liquid cryogen is controlled (318,320) as a function of the degree of superheat (314,316 in evaporated cryogen exiting the heat exchanger, and as a function (312) of a predetermined floor temperature of conditioned air discharged into the conditioned space.

Abstract: When, on switching off screw centrifuges, the speed has dropped to such an extent that the centrifugal force is smaller than the force of gravity, the liquid ring formed inside the centrifuge drum under the centrifugal force collapses and there is a discharge of liquid at the solid discharge of the centrifuge. According to the invention, it is proposed, immediately before reaching this critical speed, to modify suddenly and briefly the speed of the centrifuge drum (2) and/or of the screw conveyor (4) so that the liquid ring "screws" through the screw turns (3) of the screw conveyor (4) to the other end of the centrifuge (1) - towards the discharge openings (5) for the liquid (11). <IMAGE>

Abstract: This invention relates to a process for producing a nonequilibrium distribution of methylamines by the catalyzed reaction of methanol and/or dimethyl ether with ammonia and by the catalytic reforming of a methylamine containing feedstock. One process selectively affords a reaction product enriched in mono and dimethylamines and low in trimethylamine, at high conversion of methanol or dimethylether. A variation of the process effects reforming a methylamine containing feedstock, optionally containing ammonia over a catalyst. The key to achieving this low TMA selectivity at high conversion resides in the use of a microporous zeolite, preferably chabazite, catalyst having a geometric selectivity index (GSI) less about 3, a shape selectivity index (SSI) greater than about 5 and a sorption capacity for 1-PrOH of at least 0.5 mmol/g.

Abstract: Apparatus for providing displays in which the locations of nodes of a graph relative to each other are a function of the significance of a relationship between the nodes. The technique used to locate the nodes produces groups of nodes with significant relationships to each other which are set visually apart from the other nodes. The relationships between the nodes are defined by using a statistic to give weights to links between the nodes. Statistics may also be used to determine the size, shape, and color of the nodes and the color and width of the links. The display may also include histograms which show the numbers of links or nodes which have given values of the statistics and which relate the colors in which the nodes and links are displayed to values of the statistics. The histograms may further be used to interactively define masks for links and nodes, and masked links and nodes are not taken into account in making the display.
