Abstract: A device for taking milk by creating a vacuum in its container and supplying it already whipped directly to the cup for the preparation of Italian cappuccino coffee in combination with the steam nozzle of an expresso coffee machine. A device of this type comprises a tubular body having an inner conical seat in the vicinity of one end with which the output conical surface of an injector cooperates to form a space, the injector being extended in the form of a rod provided with splash-guard members up to the opposite end of the tubular body for leak-tight connection with the steam nozzle and with the tubular body. An air intake upstream of the splash-guard members and a rubber connection for taking the milk from the container are disposed to communicate with the space while at the downstream end of the conical seat there are disposed two coaxial nozzles forming a space via which the milk is whipped and discharged.

Abstract: A method of and a machine for measuring out of ground material, in particular coffee, of which the grains and beans are first of all ground and during the course of the grinding are deposited in a pre-measurement chamber. In this chamber, a piston transfers and packs the measure that is to be used, and variations in the preset measure are corrected.
