Publication number: 20230003174Abstract: A Stirling cycle machine with a liquid fuel/gaseous fuel burner. The burner may include a preheater to capture the thermal energy of the exhaust. The burner directs the preheated air to each burner head, where it enters a prechamber. Each burner head includes a fuel nozzle that directs liquid or gaseous fuel into the prechamber. The prechamber is fluidically connected to a combustion chamber via a prechamber nozzle that has a smaller opening than the prechamber. The burner head ignites the fuel air mixture in the prechamber with an ignitor located above or within the prechamber. The flame is initially lit as a diffusion flame in the prechamber. The flame is pushed out of the prechamber into the combustion chamber by an increased air flow rate. The liquid fuel from the nozzle now evaporates in the prechamber and forms a prevaporized flame in the combustion chamber.Type: ApplicationFiled: September 7, 2022Publication date: January 5, 2023Inventors: Dean Kamen, Christopher C. Langenfeld, Prashant Bhat, Stanley B. Smith, III

Publication number: 20220367027Abstract: A peristaltic pump, and related method, are disclosed that includes a cam shaft, a plunger-cam follower, a tube receiver, a spring, a plunger, a door, and a plunger lift lever. The cam shaft includes a plunger cam. The plunger-cam follower engages with the plunger cam of the cam shaft. The spring provides a bias and the plunger is biased toward the tube receiver by the spring. The plunger is coupled to the plunger-cam follower where expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates actuates the plunger away from the tube receiver. The door lever can be actuated between a first position and a second position. The plunger lift lever is coupled to the door lever to actuate the plunger away from the tube receiver when the door lever is actuated to the second position.Type: ApplicationFiled: May 26, 2022Publication date: November 17, 2022Inventors: Dean Kamen, John M.
