  • Publication number: 20080308508
    Abstract: The dual purpose rack and divider assembly of this invention has a base, wings, base slats, and cross slats which can be assemble in either a rack or a divider configuration. A mortise on the base and tenons on the wings and base slats provide an interlocking mechanism that allow transformation from a divider to a rack and to provide stability when in the rack configuration. The base has parallel mortises in a spaced relationship. The wings has one or more toes or tenons with a taper for insertion into and interlocking in the mortises on the base. The wings can be pivotally attached to the base. The base slats have one or more tenons with a taper for insertion into and interlocking in the mortises in the base. The toes on the base slats straddle the toe(s) of the wings when in the configuration of a rack. The base slats have at least two slots in a parallel spaced relationship with the slots extending half way across the base slats.

  • Patent number: 5711708
    Abstract: A two circuit timer that has a primary circuit that controls a first external load, a secondary circuit that controls a second external load, a timer that controls deactivation of the primary circuit to reset the first external load and to open the secondary circuit to deactivate the second external load, and an actuator that activates the timer and closes the secondary circuit to activate the second external load. The two circuit timer functions as a video game controller and has a cycle that is initiated by the actuator. The actuator can be a momentary contact push button, a coin actuator or accepter, a start button on a hand controller, a key pad or a key on a computer keyboard. The actuator starts the timer and closes contacts in the secondary circuit to allow the second external load to be activated. At a preselected timed interval the timer momentarily opens the primary circuit to deactivate the first external load.
