Portable dispensers and methods of use are disclosed herein. In an exemplary embodiment, a card game is played in which the object of the game is for each player to arrange, for example, six cards into three two-card combinations, with each combination having a predetermined target value of, for example, 7, 14, or 21, such that the values of the cards in each combination come as close to, but do not exceed, the target value for each respective combination. A sampling plan for measuring a characteristic of selected workpieces processed using the operating recipe is determined based on the defectivity metric. The extension cooperates with a rod serving as a stop, in such a way that rotation of the driving device together with the turntable is prevented. A backflow preventing portion is provided in the duct, and when bubbles flow back into the duct from the inner space of the drum through the blowhole, the backflow preventing portion functions as resistance for preventing the back flow of the bubbles. The inner surface of the cap cooperating with the screw thread, at least one outlet port for the hydraulic-fluid flow towards a hydraulic circuit.
