Abstract: Disclosed are apparatus and methods for separating an egg yolk from a whole egg. Embodiments of the disclosure are described as having a vacuum-producing means coupled to a hollow cavity portion which has a yolk-entry aperture. After placing the yolk-entry aperture against a portion of the egg yolk, the vacuum-producing means may be operated to draw the egg yolk through the yolk-entry aperture thereby creating a shearing force between egg yolk and egg white that is effective for separating yolk from white. The separated yolk may be retained in the apparatus until expelled. Other described embodiments incorporate a yolk-retention aperture that is effective for both separating egg yolk from egg white and also retaining the separated egg yolk in the apparatus until expelled.

Abstract: A variable weight end structure 10 that provides for variable tail-end weighting of racquets, clubs, or sporting equipment with handles. The end structure 10 comprises an interface element 17 and a weighting element 18 that allows a player to quickly and easily add and vary tail-end weights. The variable weighting end structure 10 provides a player with a more versatile racquet/club, providing increased power and control, reduced shock, while not significantly changing swing weight.
