  • Patent number: 5618096
    Abstract: Light emitting panel assemblies include light emitting panel members and one or more light sources positioned/embedded in a light transition area, which increases the efficiency of light entering the panel members along the light input area to be emitted from one or more light emitting surfaces along the length of the panel members. Light may be reflected or refracted by a surface which changes the path of a portion of light such that it enters the input area of the panel member at a more acceptable angle. A uniform light output distribution may be produced by utilizing a pattern of light extracting deformities.

  • Patent number: 4067306
    Abstract: A solenoid actuated device to permit a carburetor throttle valve to close below the curb idle position upon deactivation of an ignition system for an internal combustion engine and to prevent electrical grounding by the device when it is out of contact with the throttle arm. The solenoid actuated device has an armature mounted in a housing for movement between energized and deenergized positions and a shaft extending through the housing is mounted within the bore of the armature for movement therewith. The shaft is in contact with the throttle arm adjacent one end and an electrical lead extends from the other end of the shaft. An insulating sleeve is positioned between the shaft and armature to prevent electrical grounding of the shaft when the shaft is out of electrical contact with the throttle arm. The insulating sleeve and shaft therein may be adjusted longitudinally relative to the armature to control the position of the throttle arm.
