Abstract: A method, system, computer program product, and data structure for trading in which a standardized contract is traded. The contract obligates a buyer and a seller to settle the contract based on a price of the contract at a first effective date. The contract is traded through an exchange that guarantees payment to the buyer of any amount owed to the buyer from the seller as a result of the contract and that guarantees payment to the seller of any amount owed to the seller from the buyer as a result of the contract. The price of the contract is determined based on preselected notional cash flows discounted by at least one point on an interest rate swap curve obtained from a preselected swap rate source.

Abstract: An improved intake valve for an internal combustion engine is provided. The improved valve has a ridge extending from the downstream side of the periphery of the valve head to aid in the improved aerodynamic flow of the fuel mixture gas through the valve opening. The ridge acts as the center portion of an ideal air foil and thus reduces the back pressure, and hence the drag, presented by the valve to the flowing gas fuel mixture. By reducing the drag, more fuel mixture in a given time and space can be provided into the combustion chamber and the horsepower of a given size engine is increased. In other words, a smaller and lighter engine can be used to do the same work, with the net result of better fuel economy, better packaging, lower production costs and so forth. Alternatively, a given sized engine can be made to produce more power.
