Abstract: The present invention provides a comprehensive, integrated, computerized system for facilitating transactions in goods or services. The system is capable of facilitating transactions from early or initial stages, such as an electronically proposed purchase order, through to later or final stages, such as payment on an invoice or invoices relating to the transaction. The system is integrated to include the participation of various providers of services ancillary to transactions, such as guarantors, insurers, and shippers. The system may allow sellers or buyers to electronically propose amendments and counter-amendments to, and to amend, through mutual agreement, a purchase order agreement. Any amendments are accounted for in later stages of the transaction facilitated by the system.

Abstract: An electromechanical VVA system for controlling the poppet valves in the cylinder head of an internal combustion engine. The system varies valve lift, duration, and phasing in a dependent manner for one or more banks of engine valves. A rocker subassembly for each valve is pivotably disposed in roller bearings on a rocker pivot shaft between the camshaft and a roller follower. A control shaft supports the rocker pivot shaft for controlling a plurality of rocker subassemblies mounted in roller bearings for a plurality of engine cylinders. The control shaft rotates about its axis to displace the rocker pivot shaft and change the angular relationship of the rocker subassembly to the camshaft, thus changing the valve opening, closing, lift and duration. An actuator attached to the control shaft includes a worm gear drive for positively rotating the control shaft.

Abstract: An electromechanical VVA system for controlling the poppet valves in the cylinder head of an internal combustion engine. The system varies valve lift, duration, and phasing in a dependent manner for one or more banks of engine valves. A rocker subassembly for each valve or valve pair is pivotably disposed on a control shaft between the camshaft and the roller finger follower. The control shaft may be displaced about a pivot axis outside the control shaft to change the angular relationship of the rocker subassembly to the camshaft, thus changing the valve opening, closing, and lift. A plurality of control shafts for controlling all valvetrains in an engine bank defines a control shaft assembly. The angular positions of the individual control shafts may be tuned to optimize the valve timing of each cylinder. The system is applicable to the intake and exhaust camshafts of diesel and gasoline engines.
