Abstract: A hardgeared infinitely variable transmission (IVT) is provided in which at least one quick return mechanism is hardgeared to the rotating transmission input shaft. The quick return mechanisms convert the rotating motion of the transmission input shaft to a variable motion consisting of a near constant linear velocity portion and a rapid return portion for each cycle of input rotation. The near constant linear velocity portion of the motion of each quick return mechanism is selectively engaged to a conversion device which translates the motion to an output rotation. The input/output speed ratio is adjusted by varying the amount and direction of quick return mechanism motion which is selectively engaged to the conversion device. An infinite range of speed ratios can be produced, as well as output rotation in both forward and reverse directions relative to the input rotation.
Abstract: A particle feeding hopper having an elongate agitator positively driven around the hopper's inner surface by a reciprocating ratchet mechanism. The mechanism drivingly engages a circular chain connected to the agitator.
Abstract: A mechanical drive system permits a single electric motor to drive at least three rotary components necessary to the cold starting of a Stirling engine. These components comprise a rotary preheater, an air atominzng pump for facilitaing proper injection of fuel particle size, and a combustion air blower, all necessary to heat the working gas of a Stirling engine prior to engine cranking. The drive system employs a shaft, offset from the engine driven element but drivingly connected thereto. A clutch is interposed between the offset shaft and the rotary starting components, as well as between the electric motor drive and said components. Thus, drive is alternatively transmitted, first from said motor to the component to permit engine temperature increase, cranking is then established, and then drive is transmitted from the engine driven element to said components.
