Abstract: A topping dispenser has a housing with a supporting base forming its floor. The supporting base has a base evacuation hole formed in it. There is a sliding gate installed within the base. The sliding gate is biased away from a first end of the base by a spring. The sliding gate also has an evacuation hole formed in it. There is also an agitating finger fixed on the sliding gate which moves through the toppings held in the housing. When the spring is resisted, the sliding gate evacuation hole and base evacuation hole move into alignment as the agitating finger moves through the topping particles separating any adhered or caked particles which are thereby separated and more easily pass through the aligned base evacuation hole and gate evacuation hole.

Abstract: An abdominal exerciser has base and back frames pivotally mounted for movement between upright and recumbent positions, and a seat frame with cushion rotatable on the base frame. A low friction journal between the base and seat frames supports a user's weight. The journal is about 30 to 42% the distance from a rear end of the cushion to its front end so the user's coccyx is vertically aligned with the journal. Arms at each side of the base frame have a pair of extensions connected to either the base or seat frame, each with a U-shaped handhold lying in a plane at an acute angle of about 30 to 80 degrees to the horizontal. A pair of single pulleys or a pair of tandem pulleys are mounted near the rear of the base frame and are engaged by sleeve-covered springs for biasing the back frame toward the upright position.

Abstract: A headphone set has a pair of headphone assemblies for engagement over the ears, each with a cushion and an active noise reduction circuit for reducing noise. A sound conditioning circuit stores various conditioning sounds for the user and an external sound source amplifier in the set is for connection to an external source of sound for supplying sound from the external source to the user. A power supply powers the set and switches are provided for selecting between modes of operation for supplying no sound to the user with no active noise reduction, for supplying no sound to the user with active noise reduction, for supplying the at least one conditioning sound to the user and for supplying sound from the external sound source to the user.
