摘要： A comprehensive multiple rapper control system controls rapping intensity with enhanced accuracy, controls a large number of rappers in any desired sequence with intensity control for each individual rapper, and includes alarm circuitry for reliably indicating open circuited and short circuited conditions in the rapper coils or in the electrical connections to the rapper coils. For enhanced accuracy, a short boost pulse of full lift energy is applied immediately prior to a lift pulse of controlled energy. The boost pulse overcomes initial rapper plunger sticking forces so that total rapper plunger lift accurately reflects the electrical energy supplied during the subsequent controlled pulse. Advantage is taken of the relatively constant boost pulse which is supplied to every rapper in the system regardless of the energy supplied during the control pulse to provide an alarm circuit. Current through each rapper plunger lift coil is sensed during at least a portion of the boost pulse. An alarm condition is signaled if this sensed current is outside of a predetermined range.
摘要翻译：全面的多重敲击控制系统以更高的精度控制振打强度，以任何期望的顺序控制大量的敲击者，每个敲击器具有强度控制，并且包括报警电路，用于可靠地指示说唱器线圈中的开路和短路条件与敲击器线圈的电气连接。为了提高精度，在受控能量提升脉冲之前立即施加全升降能量的短暂升压脉冲。升压脉冲克服了初始的敲击器柱塞粘附力，使得总的敲击器柱塞提升精确地反映在随后的受控脉冲期间提供的电能。优点是提供给系统中的每个敲击器的相对恒定的升压脉冲，而不管控制脉冲期间提供的能量如何，以提供报警电路。在升压脉冲的至少一部分期间感测通过每个敲击器柱塞提升线圈的电流。如果该感测电流超出预定范围，则发出报警状态。

摘要： An electric dust precipitator comprising a chamber, a pair of dust collecting electrode groups, disposed in parallel with each other in the gas-flow direction in the chamber, the electrode groups being spaced apart by a distance of more than 400 mm, each electrode being made of a tubular member through which a cooling fluid for controlling the temperature thereof is passed and a plurality of discharging wires disposed in parallel with and between the dust collecting electrode groups wherein a high direct current voltage is applied between the discharging wires and the dust collecting electrodes, and a control system including a detecting means which detects the number and quantity of spark discharges caused by reverse ionization per unit time and a control means which controls the temperature of the cooling fluid with aid of a detected signal.

摘要： An electrostatic air cleaner having a deenergizing or grounding device operative upon opening of a closure member to ground electrical components within the cleaner cabinet. The device includes at least two spaced contacts and a bridging element. One of the contacts is connected to ground and the other to a component within the cabinet. A spring biases the bridging element toward engagement with both contacts. An operator connected to the bridging element forces the bridging element out of engagement with the contacts when the closure member engages the operator upon closing of the closure member. The operator is resilient to compensate for variances but is less resilient than the spring so as to overcome the spring.
