  • Patent number: 4458735
    Abstract: An arrangement for automatically controlling the dispensing of a beverage such as a frothy milk shake into an open mouth container such as a translucent paper or styrofoam cup. A dispensing station defines a designated position for the cup to be filled, and a dispensing nozzle is positioned above that designated position. A radiation source is positioned above the cup to direct radiation downwardly through the open mouth thereof such that it passes through the side walls of the cup. A radiation detector is positioned adjacent to an exterior wall of the cup at a vertical position thereon at which the cup holds a "full" dispensed quantity of beverage, such that it produces an output signal indicative of the radiation passing through the wall at the full position. The output signal is compared with a given threshold level, and when it falls therebelow, thereby indicating that the dispensed beverage is at the "full" height, the dispensing operation is terminated.

  • Patent number: 4447918
    Abstract: In a pop-up drain fitting threadedly secured to a spider at the lower end of the drain body, the improvement comprising a detent member pivotally joined to the lower end of the pop-up drain fitting. A stop member is disposed adjacent to the detent member to permit the detent member rotation in only one direction. The detent member depends downwardly by gravitational force to extend through the spider. Clockwise threading motion of the pop-up fitting into the drain body is permitted by the detent arm; counterclockwise rotation of the pop-up fitting causes the spider to impinge upon the detent arm and drive it into the stop member, thereby preventing removal of the pop-up fitting.
