Abstract: The present invention relates to methods of improving engine braking of a reciprocating piston internal combustion engine by variable valve actuation. One embodiment of the present invention enables independent two-valve actuation for each cylinder, and engine braking horsepower can be optimized using two-valve braking at high engine speeds and one-valve braking at low speeds. Another embodiment of the present invention enables better a sequential valve actuation to reduce engine braking load and compliance. Another embodiment of the present invention enables better engine starting and warming up by controlling timing and lift of each valve.

Abstract: The present invention relates to making optical articles such as opthalmic lenses by molding and, in particular, to using a continuous extrusion-compression molding method to make plastic lenses whereby a polymer melt is fed from an extruder or melting apparatus to a first die of a plurality of rotating or conveyed sequentially processed compression die sets comprising a first die and a second die. The die sets are positioned on die supports on a rotating turntable or conveying system, the lenses formed by compressing the die sets with pressing means associated with each die support, the lenses separated from the dies and the dies recycled to die loading and the melt feed step of the process and the process repeated until the desired number of lenses or other optical articles such as compact disk substrates are produced.
