  • Publication number: 20100011640
    Abstract: A non-interactive advertising display is provided for use by golfers in their golf carts, which supplies useful advertising information to the cart occupant(s). In some cases, the display holds print advertisements protected under a clear removable film. Furthermore, the system is free from being unduly obtrusive in comparison to some interactive advertising methods due to its static, printed delivery—which can be free from animation, video or sound—and its unique placement, mounting under the front of the roof of the cart as opposed to the roof mounting poles. The advertising display can be used to attach to many commonly occurring golf cart roof shapes. This is due to a universal design and removable mounting brackets. Furthermore, the non-interactive advertising display can be maintained without the use of tools. Because the display can be manufactured in a way that purposefully matches cart roof colors this further minimizes the display's obtrusiveness.

  • Patent number: 4337055
    Abstract: A belt tensioning apparatus for tensioning a belt that extends between a driving shaft and driven shaft which are immovably supported with respect to one another. There is a flat spring, the free end of which bears against one run of the belt at a point between the two shafts. The opposite end of the spring is rigidly fixed so as to orient the spring within the plane of the belt such that the spring elastically deflects the belt run into a taut condition. A second leaf spring supported for cooperation with another belt run. Plural flat springs backing up the first mentioned springs for increasing the force applied thereby to the belt runs.

  • Patent number: 4290205
    Abstract: A gauge for use in a wheel balancing machine for ascertaining the location of the plane of the inner edge of the wheel rim. The gauge includes a flat resiliently flexible plate which has an edge that is graduated in units of distance. Extending from the plate remote from the edge is a support bar and there is means for mounting the support bar for slidable movement along its longitudinal axis to permit positioning of the graduated edge adjacent to the inner edge of the wheel rim so that the position of the rim can be ascertained by comparing its location with that of the graduations.
