  • Patent number: 6280804
    Abstract: A novelty windmill which includes a propeller, a drive shaft which is driven by the propeller, a motion transmitter for transmitting motion to a display item, and a display item which is moved by the motion transmitter. The novelty item is placed on a vehicle, so that the windmill and display item move as the vehicle is driven. The novelty windmill preferably includes a brake mechanism which controls the speed of the windmill. The brake mechanism may be in the form of a friction member which causes frictional force on the drive shaft when an air brake lever is rotated or otherwise moved due to the force of moving air on a brake paddle member. The display item can be a movable mascot or insignia for a sports team. The windmill may be placed on a moving vehicle.

  • Patent number: 3979223
    Abstract: An improved system for electrochemical impregnation of active material into an electrode for a galvanic cell comprises utilizing a constant potential during the impregnation as well as a screen or barrier interposed, in the bath, around the electrode while it is impregnated to mitigate the deposition of active material on the outside of the electrode surfaces. A more densely packed electrode having a higher charge rating per unit volume results. In a preferred embodiment the active material comprises a minor amount of a second ion and the ratio of the two ions in the bath is maintained by use of a consumable electrode in the bath having the desired ratio of ions therein.
