Abstract: An internal combustion engine for a vehicle provides variable displacement by selectively driving one or more engine crankshafts mounted within a single unitary engine block. In several embodiments the crankshafts are connected to a common output shaft with a one-way clutch between the common output shaft and at least one of the crankshafts. In one aspect starter gearing is independently associated with each of the first and second crankshafts and a starter is provided for selective engagement with the starter gearing of either of the crankshafts. In another aspect, an accessory drive for driving accessory systems of the vehicle receives power from any crankshaft which is operating, yet is isolated from any crankshaft that is not operating by a one-way clutch.

Abstract: The high spin golf club uses modified grooves for use on all types of known golf clubs, wherein the modified grooves maximizes control of the golf ball through increasing backspin. The high spin golf club's modified grooves can be used alone or in a combination with conventional grooves to tailor the properties of the club face. The modified grooves are of varied configurations and all modified grooves can be used in combination with any other modified or conventional grooves to maximize the backspin of the golf ball and tailor the spin properties of the face of the club. Further a method for making high backspin golf clubs that reduce cover damage of golf balls is disclosed.

Abstract: An improved window sash lock keeper is provided having a slot to provide clearance for a burr, which is typically found on a surface upon which such a sash lock keeper is mounted. The improved keeper is typically mounted flush to a surface of an extruded window component. The clearance slot allows the keeper to be mounted with improved precision and thereby reduces interferences caused by misaligned window hardware.
