Abstract: A machine for dispensing an individual portion of a frozen dessert may include a cartridge cart having walls forming a cavity having a longitudinal central axis and configured to accommodate a cartridge. The cartridge may include a tube having first and second ends, a nozzle disposed at the first end, and a piston disposed between the nozzle and the second end and configured to slidably move along the tube. The individual portion of the frozen dessert may be contained within the tube between the nozzle and the piston. The machine may also include a plunger, a drive source operably coupled to the plunger and configured to drive the plunger along the central axis, and a support configured to support the first end of the cartridge such that actuating the drive source causes the individual portion of frozen dessert to dispense through the nozzle.

Abstract: A system for exchanging and storing window-display posters (1-6) has two storage areas (11,12) in which the posters are movably stored perpendicularly to their surfaces. Transport of the window-display posters between the storage zones is effected through two planes that border on the storage zones. At least one of the planes is arranged for displaying several posters. A conveyor is provided for carrying the posters into and out of the planes, as well as for guiding the posters within the planes.
