The bore includes an inlet opening configured to receive a flow of relatively high pressure fluid and an outlet opening coupled in flow communication with the inlet opening and configured to discharge an underexpanded jet of fluid when the flow of relatively high pressure fluid is received at the inlet opening. The resonance chamber and the nozzle are positioned relatively and sized to facilitate emitting a tone from the tone generator assembly having a frequency less than two kilohertz.

Abstract: Techniques for supporting an automated clearing house system (ACH) for facilitating resolution of ACH transactions. When a transaction item is blocked for an account, the associated transaction is paused so that the transaction item can be presented to the client. When the indication from the client is indicative of accepting the transaction item, the transaction is allowed to process. When the indication is indicative of returning the transaction item, the transaction is stopped and the transaction item is returned. On-line authorization maintenance information may be received from the client so that transaction items can be processed based on the on-line authorization maintenance information, which may be used edit a current authorization entry or to create a new authorization entry for a trading partner. A decision to approve a blocked transaction item may be decided by an employee of a client. However, approval may further require approval by a second employee.

Abstract: A method for monitoring operation of a rapper in an electrostatic precipitator using a rapper control system is described. The method includes determining model electrical characteristics of the rapper. The model electrical characteristics of the rapper correspond to model mechanical operating characteristics of the rapper. The method also includes storing data corresponding to the model electrical characteristics and the model mechanical operating characteristics of the rapper, determining actual electrical characteristics of the rapper, and comparing the actual electrical characteristics of the rapper to the stored model electrical characteristics to determine actual mechanical operating characteristics of the rapper.

Abstract: A pulse detonation cleaner system is described. The cleaner includes an elongated combustion chamber configured with at least one fuel injection inlet and one air inlet to provide fuel to the combustion chamber. The fuel and air are mixed and ignited to produce a flame. The flame is accelerated into a detonation as it propagates downstream through the combustion chamber. The detonation and its products are vented from the combustion chamber into a vessel to be cleaned. The shock and high-pressure products of the detonation are used to release debris from the walls of the vessel and blow them away.
