Appl. No.:

7/092970

Inventors:

Abstract:

In a reel-to-reel web transport (such as a magnetic tape recorder), apparatus is provided for accurately positioning a takeup reel to receive the lead end of a web. The takeup reel is rotated in web supply and takeup directions by a brushless direct current (DC) motor. A magnetic hysteresis brake is coupled to the takeup reel when the reel is rotated in a web supply direction. The rotational position of the takeup reel to receive the lead end of a web is coincident with a stable torque equilibrium position of the DC motor. A control circuit is provided (1) for commutating the DC motor in a supply direction to couple said brake to said takeup reel, until a position sensor associated with the reel is actuated; (2) for commutating the motor for one more cycle in the same direction to bring the motor to rest at a position past the predetermined position; and (3) for commutating the DC motor for one cycle in the reverse direction, to uncouple the brake from the takeup reel and to bring the motor to rest at the stable equilibrium position which is coincident with the web receiving position of the takeup reel.

Abstract:

The Canopy Tent Pole Mounted Bottle Opener (“Opener”) is a device that will be used for opening bottles and cans in conjunction with a canopy tent leg. While neither the canopy tent nor the canopy tent leg is a part of this patent application, the Opener is designed to be compatible and used in conjunction with several different types and brands of canopy tent legs that are already in the market. Using a simple, but effective design, the Opener can be attached to any of the canopy tent's collapsible legs and allow the user to pry open a bottle or can of his/her beverage of choice. The angle in which the Opener has been designed is unique and the only angle in which the proper amount of downward force may feasibly be applied to pry open a bottle without spilling the contents. Moreover, the protruding portion of the Opener can serve as a hook that may be used to hold a garbage bag to catch and collect discarded bottle caps. The hook may also serve several other functions such as a coat or hat rack as the user sees fit.
