    摘要: A negative glow discharge lamp, which includes a light transmitting envelope containing a noble gas film material and a pair of electrodes disposed in the envelope. Ballast capacitors are placed within the base of the lamp and preferably within a cavity formed within the wall of the base surrounding a necked-down portion of the envelope.

    摘要: A high pressure sodium arc tube assembly includes a light-transmitting arc tube containing a fill material including sodium and mercury, a pair of electrodes sealed in opposite ends of the arc tube, and a filament or other resisitive member located within the arc tube and extending between opposite ends thereof. The filament is electrically connected to the electrodes. The filament provides a sufficient electric field and an abundance of electrons dispersed throughout the discharge region to initiate an arc discharge when the electrodes are energized. The filament is selected to produce an electric field in the discharge region prior to initiation of arc discharge of at least 20 volts per centimeter. After an arc discharge is initiated, the voltage between the electrodes drops, and the filament is partially short-circuited by the arc discharge. The filament provides fast initial starting and fast hot restarting, while eliminating the requirement for high voltage starting pulses.

    摘要: A ladder rack device which comprises a frame mounted to a vehicle roof, the frame having at least first and second ladder retaining members and a moveable arm having a proximal and a distal end, the first ladder retaining member being mounted on the proximal end of the moveable arm, a lifting member being provided and having a first end connected at a distal end of the arm and a second end connected to the frame, the lifting member being arranged to lift the distal end of the arm and move the proximal end in an outboard direction with respect to the vehicle, the arrangement being such that the distal end of the arm can pivotably rotate and permit the arm to extend downwardly adjacent the vehicle side while a ladder retaining member thereon will be retained in a secure position. The device is relatively simple and has few moving parts.
