Abstract: A system and method for facilitating the construction of computer programs. The system enables an administrator to define dialogs associated with commands from a computer programming language. Users construct computer programs by using the dialogs. In particular, an user invokes a dialog. Code corresponding to a command associated with the invoked dialog is then automatically generated. The code is in a form and has a syntax defined by the computer programming language. The code is inserted into the computer program being constructed. Computer programs can also be constructed using dialogs and objects. In particular, a plurality of objects each corresponding to a resource in a target environment are defined and instantiated from a plurality of object classes. At least one of the dialogs is associated with each of the objects. An operator selects one or more of the objects (representing the resources in a system), and invokes a dialog associated with the selected objects.

Abstract: In some embodiments, the invention includes a method of regularity extraction including generating a set of templates for a circuit through computer automated operations on a description of the circuit. The method also includes covering the circuit with instances of a subset of the templates. In some embodiments, the set of templates includes single-principal output templates, where a single-principal output templates is a template in which all outputs of the template are in the transitive fanin of a particular output of the template. The set of templates may also include tree templates. In some embodiments, the set of templates is a complete set of templates given certain assumptions including that the set of templates include all maximal templates of involved classes of templates and a template is not generated through permuting gate inputs.

Abstract: A system and method for object representations of program and script components. A graphical user interface displays a plurality of program components in a plurality of rows in a scrollable table. Each scrollable table comprises a first column that contains iconic representations of the program components and a second column that contains generated program code for the program components. An operator edits the program by manipulating the icons, editing invocation of dialogs or editing the generated program code directly.

Abstract: A system and method for object oriented central maintenance. Program code for a plurality of program components is generated based on operator interaction with dialog definitions. Central maintenance is performed by changing the definitions of at least one of the dialog definitions that form at least part of a program component in the program. Program code for each program component that is based on the changed dialog definition is regenerated and replaces the previously generated program code.

Abstract: A fan apparatus 10 for use on the dashboard 101 of a vehicle 100 includes a housing member 20 having a fixed Louver element 22 for introducing ambient air into the interior of the housing member 20. The air will be heated by a heating coil member 30 and the heated air will be forced through at least one downwardly angled hinged Louver panel 25 by at least one fan member 40. Wherein, the angular orientation of the fan member 40 can be altered by the manipulation of an elongated stem element 43 which projects through an enlarged opening 26 in the housing member 20.

Abstract: Fluidics flow control of a multiphase supply using a cylindrical chamber is achieved by introducing the supply flow radially into the chamber. The supply flow exits through a port in the center at the chamber. A control fluid is then introduced tangentially about 90.degree. upstream from the supply port. A second control fluid port may be added about 90.degree. upstream from the first control fluid port, but preferably two sets of supply and control ports are added with like ports diametrically opposite each other. The control fluid flows against the circular wall of the control chamber, which introduces a vortex in the flow of the supply flow that decays into a spiral path to the exit port in the center of the chamber. The control flow rate may thus be used to control the spiral path, and therefore the supply flow rate through the exit port.

Abstract: The electric parameter metering machine comprises electric parameter pickup circuitry for sensing the instantaneous analog amplitude value of a electric parameter waveform in at least one phase in an electric power distribution system at selected time intervals during each full cycle, an A/D converter for converting the analog amplitude values to digital signals and signal processing circuitry including a memory for storing the digital signals. The signal processing circuitry includes a microprocessor operable to apply a conventional waveform analysis technique to the digital signal information collected with respect to a selected number of cycles of the electric parameter waveform to obtain an instantaneous RMS value of the electric parameter and operable to process a sequence of instantaneous RMS electric parameter values at discrete time intervals to obtain time averaged or demand electric parameter values.

Abstract: A microprocessor based recloser control has a microcomputer for causing trip and close operations of a recloser in response to the conditions of the power distribution lines being protected and operator commands. The microcomputer may be overridden by a mechanical switch in the recloser control. If power to the recloser control is lost, the microprocessor will continue to function with power storage means for a limited duration. Towards the end of that duration, this microcomputer will power down the microprocessor in an orderly manner allowing automatic return to its functions when power is restored. After the microprocessor is no longer functioning, a secondary overcurrent trip circuit is relied upon to cause a trip operation of the recloser for extended durations of power outage. The secondary overcurrent trip circuit can be disabled by the microprocessor.

Abstract: A voltage regulating transformer utilizing a microprocessor and a versatile multipurpose set of hardware modules and software modules it is described. A standard tap changing mechanism is driven in response to an analog control signal to change the output voltage of the transformer in response to digitally sampled values of voltage and current which have been transformed from the time domain to the frequency domain through a software program using Fourier transform techniques. The output current is also transformed and digitally processed to determine the power factor and the direction of power flow through the transformer. By inserting the digital values of the line characteristics to the load, line drop compensation is provided for. The difference in voltage across the input and output transformers is transformed to a digital signal and internally processed to provide an indication of the position of the tap changing mechanism without relying upon mechanical devices.

Abstract: A method of desulfurization is described in which high sulfur coals are desulfurized by low temperature chlorinolysis (12) of coal in liquid media, preferably water, followed by hydrodesulfurization (26) at a temperature above 500.degree. C. The coals are desulfurized to an extent of up to 90% by weight and simultaneously dechlorinated to a chlorine content below 0.1% by weight. The product coals have lower volatiles loss, lower oxygen and nitrogen content and higher fixed carbon than raw coals treated with hydrogen under the same conditions.Heating the chlorinated coal to a temperature above 500.degree. C. in inert gas such as nitrogen results in significantly less desulfurization.

Abstract: A method of desulfurizing coal is described in which chlorine gas is bubbled through an aqueous slurry of coal at low temperature below 130 degrees C., and at ambient pressure. Chlorinolysis converts both inorganic and organic sulfur components of coal into water soluble compounds which enter the aqueous suspending media. The media is separated after chlorinolysis and the coal dechlorinated at a temperature of from 300 degrees C. to 500 degrees C. to form a non-caking, low-sulfur coal product.
