Latest Patents

Chaffee holds a patent for a "Fluid bearing supporting system for rotary drums and the like." This invention features a large diameter rotary drum that is horizontally supported by a series of saddle-like expansible liquid bearing pads. These pads have a large effective contact area with the drum, ensuring stability and support. Additionally, a fixed saddle adjacent to each bearing saddle supports the drum when it is not floated upon the bearings. The system is designed to keep the bearings and the lower portion of the drum submerged in a liquid within a sump, which is maintained at a specific temperature through a cooling tower or heat exchanger. The design includes separate adjustable valves that supply activating liquid to each bearing pad, along with individual pressure gauges for monitoring.
