Abstract: A torch ignition apparatus and method, the apparatus including a secondary, torch ignition piston interconnected to the primary piston and operable to produce through compression ignition of a carbureted fuel/air mixture a jet of hot gases capable of igniting a fuel and air mixture compressed in a primary combustion chamber by the primary piston. The apparatus also includes a secondary fuel system for supplementing a low ratio fuel/air mixture in the combustion chamber and a novel hoop valve and exhaust port system for providing a unique, highly efficient flow-through system for exchanging gases in the combustion chamber.

Abstract: A pipe hanger/snubber for supporting and/or protecting high-pressure piping and the like against damage by seismic, vibrational, and thermal shocks to the mechanical integrity of the piping system. The apparatus includes a sealed snubber cylinder containing a non-Newtonian fluid as the hydraulic fluid medium. A working shaft extends completely through the snubber cylinder. A shaft-mounted, perforate load nozzle is moved longitudinally through the non-Newtonian fluid in the snubber cylinder to thereby dissipate the shock forces. Shaft-engaging seals at each end of the snubber cylinder inhibit leakage of the non-Newtonian fluid from the snubber cylinder. Selectively, reservoir apparatus containing non-Newtonian fluid are provided adjacent at least one seal to compensate for leakage, if any, of the non-Newtonian fluid through the seal.

Abstract: A chain-drive transmission including two sets of a plurality of sprockets, each set rotatably mounted on a rotatable shaft. Sprockets on each shaft are paired with a corresponding sprocket on the other shaft and are joined by the drive chain. The diameters of each pair of sprockets are selectively predetermined so as to provide a desired speed range for the chain-drive transmission. A selector and interlock mechanism is also provided so as to suitably select and interlock each preselected sprocket with its respective shaft thereby transmitting torque between the two rotatable shafts through the chain.
