Abstract: An efficient and cost effective system for the collection, concentration, and delivery of disperse solar energy to a central location for use in electrical power generation. The system includes a unique structural design for a strong lightweight parabolic dish heliostat. It couples this heliostat with a small collimating lens (or mirror) and a flat side mirror to redirect the resultant concentrated solar energy beam to a central receiver.

Abstract: A fuel vapor recovery system for an automotive vehicle includes a fuel tank, a first vapor recovery canister, a second vapor recovery canister, and a bypass flow metering element. The first canister has an inlet communicating directly with the fuel tank and an outlet. The second canister has an inlet communicating directly with the outlet of the first canister. The bypass flow metering element is disposed between the inlet and outlet of the first canister and directs a predetermined portion of the vapor from the tank directly to the inlet of the second canister, thereby reducing the vapor flow restriction through the system.
