Abstract: A hot and cold mixing valve for connection to hot and cold water lines for feeding a shower head, bath tub or the like. Control is effected by upper and lower valve discs coupled to a stem and spaced axially from one another to provide a mixing space between them. An upper inlet opening terminates at the face of the upper disc while a lower inlet opening terminates at the face of the lower disc, the openings being in substantial alignment with one another. Each of the discs has an arcuate through-opening of tapering width so as to define a wide head and narrow tail subtending an arc of preferably 315.degree.. An outlet port is formed in the valve body in communication with a mixing space between the discs. The through-openings are oriented head opposite tail in complementary overlapping relation so that dead sectors on the discs are simultaneously alignable with the inlet openings to define the off position.

Abstract: An impression cylinder for a rotogravure press having a recessed sheet stock gripper mechanism with a swivelling mechanism that swivels the grippers within the cylinder contour by revolving the grippers around a theoretical axis on the cylinder contour.
