Abstract: Medical devices are disclosed that include a tunable ultrasonic transducer assembly, as well as related assemblies and methods. A medical device includes a transducer controller, a transducer having an input side connected with the ultrasound transducer controller via an input electrical conductor, and a tuning assembly that is electrically connected between the input electrical conductor and the ground potential. The tuning assembly is adjustable to provide a selected inductance from a number of different inductance values. The tuning assembly includes a multi-position switch and a plurality of tuning inductors. The switch is operable to select combinations of tuning inductors, thereby providing a selected inductance value between the input electrical connector and the ground potential so as inductively tune the medical device.

Abstract: Pellets can be injected into oil and gas production equipment that may contain stagnant or slow moving system fluids to treat the stagnant or slow moving system fluids to prevent conditions such as corrosion. The pellets have a density such that they may be moved through the equipment by system fluids passing therethrough. When the pellets come into contact with the stagnant or slow moving system fluids, sufficient pellets enter the stagnant or slow moving system fluids to treat it. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: The present invention provides a device for producing a water treatment solution from a solid chemical block for distribution into a water system selected from the group comprising an institutional water system and an industrial water system. The device includes a housing to contain the solid chemical block. A fluid, preferably water at ambient temperature, is introduced into the housing to dissolve the block and form a liquid solution that may then be dispensed into either an institutional water system or an industrial water system. A method of dispensing the liquid solution with the device is also provided.
