Abstract: The helmet uses a new fastener to fasten a cage to the helmet shell allowing sides of the cage to be mounted directly against the shell, reducing the width of the shell on each side. A ball is attached to a portion of a bar of the cage to act as a limit stop precluding movements of the cage with respect to the helmet. A chin bar is fastened to the helmet at two points on each side of the shell. The shell is molded with recessed portions designed to receive the two branches of the chin bar on each side where they will be fastened to the shell so that the outer surfaces of the chin guard are flush with the shell at the locations of attachment to provide a smooth transition and reduce weight. An adjustment device to adjust the fit of the helmet to the user includes a star wheel on each side of the helmet attached to an arcuate flexible strip extending rearwardly around the occipital area of the skull.

The lateral adjustment device is between the outer shell and the inner padding and comprises a first leg with a distal end fixed to the outer shell or the inner padding; a second leg; a connecting leg portion interconnecting the first and second legs; a third leg with a distal end mounted to the second leg; and an actuator for moving the second leg between first and second positions with respect to the third leg while pivoting the connecting leg portion such that the first and second legs are movable from a first orientation to a second orientation. In the second orientation, the first and second legs lie in spaced planes.

Abstract: Embodiments of an eye protector are made of a molded plastic part connected with a metal part. The plastic part consists of a generally C-shaped configuration with an elongated portion overlying the eyebrows and arcuate fingers designed to overlie the wearer's cheekbones. The metallic part includes an arcuate portion staggered significantly forwardly with respect to the plastic part. The horizontal stagger virtually precludes a ball from impacting on both the plastic part and the metallic part simultaneously, and the thin profile of the metallic part causes deflection of a ball rather than rebound. Embodiments also include a downwardly depending inverted V-shaped portion that protects the wearer's face below the eyes.

Abstract: An internal combustion engine with a plurality of cylinders operating in a four-stroke mode, with pistons moving with reciprocating motion, employs at least one holding tank that is formed within a branch of an intake manifold. The holding tank may be shared among a plurality of cylinders. The holding tank, in response to an opening and a closure of a holding valve within the manifold, serves alternately as a conduit and a tank to convey a pre-combustion gas (fuel-air mix in gasoline engines) to and from the cylinders. Intake valves are held open beyond termination of induction strokes for entry and extraction a quantity of pre-combustion gas from a cylinder to reduce the compression ratio to a value less than the expansion ratio.

Abstract: The eye guard, while complying with ASTM F803-03, has been ergonometrically designed to comfortably fit on the user's face, and to provide openings for the eyes allowing clear vision while at the same time protecting the eyes from impacts from a lacrosse ball. The eye openings are completely open and have dimensions intended to preclude a lacrosse ball from passing therethrough. The upper edges of the eye openings are displaced rearwardly with respect to the lower edges a sufficient distance to preclude a lacrosse ball from striking the two edges simultaneously in a direction that could possibly cause an eye impact. That displacement is specifically devised to cause a lacrosse ball striking one or the other of the edges to be deflected away from the eyes of the player. The upper edge of the eye openings also defines the lower edge of a visor surface. That visor surface transitions from the openings to the rearward edge of the eye guard where it engages the face of the user above the eyes.

Abstract: Lateral displacement shock absorbing arrays include features allowing them to be effectively installed in environments including helmets having arcuate surfaces. Slotted webbing between adjacent tubes permits their respective axes to tilt with respect to one another to accommodate helmet shape. In this way, the slotted webbing permits each tube to assume an orientation with its axis perpendicular to a tangent to the outer surface of the helmet at that location so that the tube is best aligned with likely impacts. Plural arrays may be assembled together in numerous ways including using a piece of material to which they may be affixed through any one of numerous ways including tabs and slots, posts and holes, stapling, adhesives, laminating, and integrally molding the arrays and material as a one piece assembly. A variety of peripheral shapes for the tubes of the arrays are also contemplated as are numerous materials of construction.

Abstract: A two-stroke cycle internal combustion engine has a cylinder with a cylinder head closing off an end of the cylinder, a crankshaft and a piston connecting with the crankshaft to move the piston in a reciprocating movement within the cylinder. Intake and exhaust valves move into and out of a combustion chamber for openings and closures of the valves. A mixture of fuel and air is forced into the cylinder during an open interval of the intake valve beginning in the middle of the upstroke and terminating in a range of 20-60 degrees before top dead center to improve efficiency and choice of fuel by minimizing compressive forces of the piston during the upstroke. Timing of the closure of the intake valve may be delayed automatically with a reduction in crankshaft angular speed.
