摘要： Method and apparatus for controlling an evaporative gas conditioning system utilizes a controller for controlling the rate at which liquid is introduced into a conditioning chamber, thereby closely controlling the rate at which temperature within the conditioning chamber is adjusted to a desired temperature. Nozzle characteristics of a plurality of different nozzle types are stored in a memory associated with the controller, so that when existing nozzles are replaced with a different nozzle type, an operator can select the new nozzle type, and data stored in memory will be retrieved to permit efficient control of the system without the necessity for manual reconfiguration. Additionally, spray nozzles for spraying water into the conditioning chamber of the system are organized into banks of nozzles, and the banks of nozzles are controlled to maintain optimum water flow through each nozzle, and to evenly distribute the water into the conditioning chamber. Additionally, steady state or stable operation of the system is monitored and data indicative of operating conditions during stable operation, for various conditions, are stored in memory. Upon a change in conditions, such as from a mill on to a mill off condition, data indicative of stable operation with respect to said operating condition is retrieved, and utilized in controlling system 10, particularly, in controlling the volume of liquid introduced into the conditioning chamber, to thereby drastically reduce the transition time associated with a change in mill on/mill off condition.

摘要： A method and apparatus for controlling power to a precipitator 27. After each spark the power to the precipitator is reduced to zero, increased along a fast ramp 15 for a fixed period of time and then increased along a slow ramp 17 until a spark occurs. The fast and slow ramp data is computed and stored (memory 48) and then retrieved after each spark. The data retrieved is the data corresponding to the firing angle at the last spark. Means are provided (selector 51 and memory 52) for dividing (frequency divider 45) the retrieved slow ramp data by a number to select the number of sparks per minute. Also the AC current and the AC voltage in the power to the precipitator are detected and the RMS values are obtained (32 and 34) and compared 35 and if the difference is above a predetermined value the power is disconnected (relay 36 and contacts 23 and 24).

摘要： An electrically variable current limiting reactor which is usable in association with a power supply for an electrostatic precipitator is disclosed herein. The current limiting reactor is capable of having the inductance value thereof varied responsive to system operation conditions. Most particularly the inductance of the current limiting reactor can be modified responsive to the form factor of the sinusoidal AC input current to the power supply transformer. Additionally the inductance of the current limiting reactor can be controlled responsive to the fractional conduction of the full wave rectified current waveform at the output of the full wave rectifier of the power supply. Other conditions can be monitored to control the inductance value of the current limiting reactor such as physical system parameters. An automatic operating control may modify the inductance of the current limiting reactor responsive to the current entering the primary of the transformer of the power supply.

摘要： This device for inductively heating and fusing thermoplastics includes an alternating current passing through a tank circuit, the inductor member of the tank circuit being wrapped around a curved pole piece of a ferromagnetic material. The magnetic flux arising within the inductor coil member flows to the ends of the pole piece and into a screen placed between the materials to be joined. The flux induces a current in the screen, and heat is generated to melt the thermoplastics together. Because only 30-150 watts of power are passed through the tank circuit, a wire which will remain cool under operational wattage may be selected, making air or fluid cooling unnecessary.

摘要： A multiple rapper control (10) for an electrostatic precipitator for monitoring and individually controlling each of a plurality of rappers based on computer (12) stored rapper characteristics including the voltage type, the voltage level, the pre-set electrical input current, the minimum increment between energization cycles, and the maximum duration of energization. Each rapper is connected to a TRIAC switch device (20) linked to a computer (14) and a power control means (16) to vary the input power to each rapper supplied from a power source (18). Current detecting means (22) is bi-directionally connected to the computer (14) and is connected to the power control means (16) to sense and measure the peak electrical input current to each rapper. A preselected logic sequence stored in the computer (12) controls power to each rapper. Optional polarity reversal means (37) eliminate undesirable magnetization of rapper components.
