Abstract: An electronically-controlled locker system that utilizes distributing processing to control access to, and assignment of, a plurality of lockers in a school, workplace, fitness center, etc. The system uses a plurality of locker control units that control access to a corresponding set of lockers based on user inputs and on user/locker authorization data that is provided from a central administrator workstation. This administrator workstation communicates with a system control unit that is in communication with every locker control unit and which allows cross-communication between locker control units.

Abstract: A dished screen placed in engine intake manifold openings beneath a carburetor in the path of intake air flow with, under a one-barrel carburetor one recess dished screen being used, and with a two-barrel carburetor two recess dished screens being used. The screen units are positioned so that fuel laden air from the carburetor passes through screening of the screen units with the mesh and wire size of the screening coupled with depressed dished shape of the screen units such as to optimize vaporization atomizing of fuel in the fuel air mixture being fed to the engine. The proper shape and screening size of the dished screen units is an excellent trade-off of intake air/fuel mixture flow obstruction for more efficient fuel utilization resulting in more power and significantly improved mileage and decreased undesired emissions.

Abstract: Disclosed is a system for injecting a mixture of vaporized fuel and air into the intake manifold of an internal combustion engine downstream from the carburetor throttle valve. The system includes a sealed vaporizer operationally parallel with the conventional carburetor system. The vaporizer includes a stabilized float valve for controlling fuel flow therethrough and various check valve arrangements and component arrangements which eliminate any possibility of lost fuel in case of collision or upset of a vehicle powered by an engine employing the vaporizer system.
