Abstract: The piston of an internal combustion engine has an odd number of sockets formed in the top surface thereof. With the piston in its top dead center position, a thin slit is formed between the cylinder head and the top of the piston. The sockets form acoustical chambers for detonation waves which may be generated in the cylinder such that with the piston in its top dead center position, these detonation waves travel in random fashion between the acoustical chambers formed by the sockets thereby attenuating such waves and minimizing the effects of detonation.

Abstract: This invention relates to improvements in engines of the reciprocating piston type, especially reciprocating piston internal combustion engines suitable for stationary and non-stationary uses. The pistons of the engine are operatively connected to the drive shaft of the engine via an elongated gear-roller gear pinion mechanism. In association with a cylinder-piston unit of the engine there is provided a roller gear pinion, engaged with the drive shaft such that rotation thereof rotates the drive shaft. An elongated roller gear is pivotally connected via an end to a piston, and the opposite open end of said elongated roller gear is meshed with the roller gear pinion. The elongated roller gear is guided through a path via appropriate mechanism which maintains continuous contact between said gears such that reciprocation of the piston within a cylinder produces rotation of the drive shaft.

Abstract: In a two-stroke spark ignition engine, fuel is injected through the cylinder wall at a location opposite to and above the level of the exhaust port (120). The fuel is delivered in the form of a number of streams such as, for example, streams (60), (61), (62). One of the streams (60) is directed upwardly across the cylinder to deliver fuel towards the combustion chamber cavity (122). This stream (60) is arranged not to impinge on the spark plug (123) but is caused to create a fuel rich cloud within the cavity (122). Streams (62) are directed downwardly and outwardly from the injection location and an optional stream (61) may be directed across the cylinder towards the exhaust port side of the cylinder.

The free piston includes a projection which abuts an abutment in the second cylinder and motion of the free piston is damped. Valves in the second cylinder maintain the desired pressure in the pneumatic cushion.

Abstract: An instrument panel member comprising a multiple-ply back sheet of fiberglas reinforced material impregnated with a polyester resin, a multiple-ply front sheet of the same material and one or more electroluminescent (EL) lamp elements positioned therebetween. The overall structure is cured at a temperature and pressure selected to provide adequate curing without damage to the EL lamp elements and so as to minimize warpage of the final structure. The thickness of the back sheet is selected to accommodate the dimensions of the EL lamps and any electrical connectors used therewith while the thickness of the front sheet is normally much less and need only be such as to permit light from the EL lamps to be seen therethrough.

Abstract: A piston for an internal combustion engine including a crown, a skirt and bosses. The skirt has a circumferentially extending faucet rib in a lower portion of the skirt and reinforcing ribs which extend in a thrust and thrust-opposing direction of the piston from the bosses straight to the faucet rib. Reinforcing ribs increase the rigidity of piston in the thrust and thrust-opposing direction and suppress parmanent deformation of the skirt in the thrust and thrust-opposing direction, resulting in decreasing slapping sounds in a piston and cylinder structure without sticking of a piston with a cylinder bore.
