A device for storing and dispensing different product possesses at least two interlocking product dispenser units each possessing a product dispensing outlet through which stored product may be selectively dispensed. The devices are connected in series through an insulating film using a wiring layer formed on the surface of the substrate. Methods and systems are also disclosed for handling requests to perform database operations on data that is in the process of being redistributed. The total energy detected in the signal being below a noise threshold indicates presence of noise or silence. Air trapped within the tubular cutting blade, between the finger and a cutout dough piece that does not form part of the dough product, may become compressed during blade retraction. The invention is characterized in that the base body for deburring the bores of a diameter<20 mm, comprises on the front thereof a smaller-diameter guide sleeve which is provided with a longitudinal bore formed therein forming a sliding guide element for guiding the control bolt tip sliding in said bore.
