Abstract: A drilling bit for drilling earthen material such as an oil well rotary cone drilling bit, which includes means for preventing foreign particles such as sand, rock cuttings, etc., from reaching the rotational bearings of the bit cones. This end result is principally achieved by means of a centrifugal slinger disc or wall which is positioned in external concentricity with the drill bit cone bearing, and operates to drive granular particles away from the bearings, thereby preventing such particles from reaching these bearing surfaces. The granular particles are driven by the slinger action through a series of apertures forming a channel running out to a peripheral region of the bit cones. A channel continuation is also provided for lubricating fluid, which may comprise ambient water or oil placed in chambers surrounding the bearings, this channel providing access for such lubricating fluid inwardly to the bit cone bearings. A disc-shaped wall member is provided opposite the slinger disc to minimize the escape of oil from the chambers when the bit is stationary. A ring member carrying a plurality of curved vanes, this ring member being externally concentric with the supporting shaft of the cone and located near the outer periphery of the bit cone may also be employed to prevent larger foreign particles, such as cuttings, from entering into the region of said slinger.

Abstract: A two cycle, spark ignition internal combustion engine of the class having a combustion chamber divided into a relatively small ignition region and a larger combustion region including the cylinder and piston is defined. Substantially stoichiometric fuel-air mixtures are independently supplied to the ignition region in substantially fixed quantity and to the larger region in variable quantity and compressed simultaneously so that the mixtures remain completely separated prior to ignition. The mixtures are stratified with respect to excess air supplied to both regions and to exhaust gases in the engine cylinder, and combustion initiated in the ignition region ignites the variable-sized mixture in the larger region. Burning proceeds from stoichiometric mixtures to lean mixtures as the stratified excess air is mixed into the burning gases. When no fuel is supplied to the large region, the small region functions independently and burns its fuel efficiently. The exhaust gas recycled in the cylinder acts to stabilize the combustion by retaining heat from cycle to cycle at light load and absorbing heat at heavy load.

Abstract: A method for operating a two cycle, spark ignition, internal combustion engine of the class having a combustion chamber divided into a relatively small ignition region and a larger combustion region in which the piston reciprocates. Substantially the same stoichiometric fuel-air mixtures are independently supplied to the ignition region in substantially fixed quantities and to the combustion region in variable quantities. These mixtures are compressed simultaneously so that they remain completely separated prior to ignition. The mixtures are stratified with respect to excess air supplied to both regions and to exhaust gases in the engine cylinder, and combustion initiated in the ignition region ignites the variable-sized mixture in the larger region. Burning proceeds from stoichiometric mixtures to lean mixtures as the stratified excess air is mixed into the burning gases. When no fuel is supplied to the combustion region, the ignition region functions independently and burns its fuel efficiently. The exhaust gas recycled in the cylinder acts to stabilize the combustion by retaining heat from cycle to cycle at light load and absorbing heat at heavy load. Stratification is obtained partially by providing separate chambers for the ignition region and the combustion region, but principally the stratification is maintained by means of stable dynamic flow patterns established in said regions.
