Latest Patents
One of Trowbridge's latest patents is a power converting apparatus and method. This invention comprises a transformer and a converting circuit designed to convert direct current into a series of pulses. The primary winding includes a pulse train that forms an effective current with reciprocal positive and negative sine wave components for each half cycle of a chosen frequency. Additionally, a gating circuit is mounted with the transformer to sequentially pass the pulses in the positive sine wave components, followed by the pulses in the negative sine wave component. This setup allows for the formation of a chosen frequency alternating current component. A filter is also included to remove selected components of the received signal while providing an output of the chosen frequency alternating current.
Another significant patent by Trowbridge is a method for acoustical cleaning. In this exemplary embodiment, the efficiency of an acoustic-energy-type cleaner for vessels, such as heat exchangers, is greatly enhanced. This is achieved by propagating a plurality of opposing acoustic wave trains through the fluid in the vessel. The method involves continuously varying at least the frequency or phase relationship of these opposing wave trains to create constructive interference. This results in a series of augmented acoustic waves that are spatially displaced in relation to each other and successive in time interval, effectively sweeping over the surfaces of the body to be cleaned.
