Latest Patents

One of Larson's latest patents is for a reciprocating engine piston seal. This apparatus is designed to seal the gap between a piston and the engine cylinder wall in either a reciprocating engine or a reciprocating compressor. It features a series of functionally identical, gas-bearing-supported seal blocks that are positioned in a circumferential slot around the engine piston. Gases from the engine chamber are fed to the gas bearing, which supports the seal block during piston travel. The seal block also includes a gas accumulator cavity for gas storage, with an orifice that feeds gas from the accumulator to the gas bearing interfacing with the engine cylinder wall. Additionally, the apparatus incorporates a reaction piston that receives gas from the engine chamber.

Another significant patent by Larson is a flow control device for solid particulate material. This device is particularly useful for managing recycled granular solids in a fluidized bed combustion vessel. It consists of a horizontal material feeder conduit that connects to the fluidized bed and an upstanding material collector conduit. The collector conduit retains a quantity of material to create a pressure sealing head, allowing for controlled flow rates into the combustion vessel. A gas-assisted flow initiator and controller is integrated into the feeder conduit to direct pressurized gas into the solid particulate material, facilitating its movement into the combustion vessel.
