摘要： An industrial control system uses a number of autonomous control units, each associated with one piece of equipment in an industrial process. The autonomous control units include data indicating not only their constraints of operation but also reflecting the constraints of operation of machines to which they are attached and with which they share common operating parameters. An autonomous controller associated with a machine having operating parameters in common with another machine adopts the intersection of the ranges of the machine constraint of the two machines. Machine constraints are preserved to the extent possible as ranges so as to permit flexibility in selecting and seeking goals by the individual autonomous control units.

摘要： Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment (20) to receive a high speed serial link (28) and undertake the control of multiple control points without expensive and awkward long cable runs and electrically isolating circuits for each cable run. Energy and bandwidth limiting on the high speed link allows power levels commensurate with high data rates yet intrinsic safety of the media allowing it to freely pass in and out of the hazardous area. A mixture of intrinsically safe and non-intrinsically safe equipment (24' and 24) on the same logical rack is allowed through a bus isolator (92) providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.

摘要： A motor controller includes a set of thyristors which couple the motor to a source of alternating electricity. A detector senses when the voltage of the source makes a zero crossing. A mechanism is provided to vary the frequency of a clock signal (GATE CLOCK) at a rate determined by a user selectable input which represents the rate at which the motor speed is to change during starting or stopping. The clock signal (GATE CLOCK) is applied to a counter (71) which produces an active trigger signal (FIRE) when a given number of clock signal cycles have been counted following a zero crossing of the source voltage. The active trigger signal causes a trigger pulse circuit (72) to apply a brief trigger pulse to gate electrodes (21, 22, 23) of the thyristors. The varying frequency of the clock signal (GATE CLOCK) alters the relative times at which the thyristors are triggered to vary the amount of voltage applied to the motor. Different frequency variation functions can be stored in a memory for the starting and stopping modes.

摘要： The normally open contact (26) is electrically connected to normal closed contact (24) and disposed within housing (22). Spanner (30) in conjunction with return spring (60) ensures that the contact (26) is switched to normally open position and the spanner (28) ensures that the contact (24) is switched to normally closed position, when housing (22) is mechanically disengaged from a switch operator (94). An Independent claim is also included for method of monitoring control circuit.

摘要： A method and apparatus for measuring the amount of free water contained within a substance includes a waveguide (64) having front and back sides (66, 68) disposed opposite each other. The waveguide (64) defines a chamber (74) for propagating a microwave signal therethrough. The waveguide (64) has an end (78) perpendicular to the front and back sides (66, 68) which forms a short within the chamber. The front and back sides (66, 68) each have an aperture (80) for passing a substance therethrough. A microwave signal in the frequency range of 10-25 gigahertz is directed through the chamber (74) wherein the generated microwave signal is reflected back from the short of the end (78). The generated and reflected signals form a ratio which is used by a microprocessor (60) along with the measurement from an adjacent sensor (12) that provides a dielectric constant measurement corresponding to the density of the substance in order to determine a weight of the substance compensated for free water.
