  • APPARATUS AND METHODS FOR DYNAMICALLY CONTROLLING THE SPACING OF CONVEYED OBJECTS
    Publication number: 20240025667
    Abstract: A conveying system employs independently controlled flights. The flights are controlled separately from a conveying surface using a linear transport system. The linear transport system allow the position of the flights to be controlled based on a parameter, such as the length of a conveyed object. The flights are pivotally mounted to a mover of the linear transport system and can pivot relative to the conveying surface to allow the flights to fit in a space between an end of carryway and a receptacle.

  • Multiple-doughnut fryer system
    Patent number: 5740720
    Abstract: A new Multiple-Doughnut Fryer System for deep frying a plurality of doughnuts simultaneously and uniformly within one convenient deep fryer. The inventive device includes a housing having a top opening, a fry tank within the housing, three wire mesh baskets removably positioned within the fry tank, and an elongated heating element near the fry tank for heating cooking oil within the fry tank. The wire mesh baskets include a vertical member secured near a looped handle, wherein an aperture and a slot project into the vertical member for removably catching upon a support pin secured to the fry tank for supporting the wire mesh basket within the fry tank.
