Power control for hot gas engines
A hot gas engine in which the expander piston of the engine is connected to an expander crankshaft. A displacer piston of the engine is connected to a separate displacer crankshaft which may or may not be coaxial with the expander crankshaft. A phase angle control mechanism used as a power control for changing the phase angle between the expander and displacer crankshaft is located between the two crankshafts. The phase angle control mechanism comprises a differential type mechanism comprised of a pair of gears, as for example, bevel gears, one of which is connected to one end of the expander crankshaft and the other of which is connected to the opposite end of the displacer crankshaft. A mating bevel gear is disposed in meshing engagement with the first two level gears to provide a phase angle control between the two crankshafts. Other forms of differential mechanisms may be used including conventional spur gears connected in a differential type arrangement

Surface treatment for valve seats
Valve with embedded fine particles of diamond in the metal surface of the valve seat resists galling, corrosion, erosion, and cold welding. Diamond powder has an average particle diameter of 0.01 micron and is used with a standard fine diamond polishing compound
Multiple Belleville spring assembly Patent
Multiple Belleville spring assembly with even load distributio
Embossed metal diaphragm has two-way stretch
Diaphragm with embossed pattern has greater structural rigidity than one with smooth surfaces, but under severe stress, tensile loads will flatten embossing. This provides necessary additional panel stretch needed to prevent rupture of diaphragm material. Hexagonal embossing-configuration allows panel stretch in any direction or in all directions simultaneously
