Abstract: The milling head (1) comprises:a principal body (2),an interposed piece (5), which is mounted to rotate on the principal body (2) and which is equipped with a first crown gear (12a),means for driving and for blocking in rotation the interposed piece (5) with respect to the body (2),a spindle-holder (3), which is mounted to rotate along axis XX' with respect to the interposed piece (5), on which is fixed a second crown (12b) adapted to mesh with the first crown (12a), and which is mobile in translation along axis XX' between a position of blockage in rotation in which the crown gears (12a, 12b) mesh in one another, and a position of setting in rotation in which the two crown gears (12a, 12b) are out of mesh,means (13) for setting in translation the spindle-holder (3) between the positions of blockage and of setting in rotation,and means (17, 18, 19) for setting in rotation the spindle-holder (3) along axis XX'.

Abstract: The machine allows filling of internally sterile plastic bags with any liquid and sealing them. The machine comprises: liquid-proportioning apparatus (1), jaws (17, 18) suitable for pneumatically holding the upper lips of the bag to be able to open, fill, close it by heat-sealing (jaws 7, 8). The most important part of the machine consists of devices (10, 11, 12) able to control the jaws to open the bag with cosinusoidal law acceleration, slowly at first, preventing detachment of the upper lips of the bag during opening, and then rapidly operating so as not to delay the successive operations of: closing, sealing and discharging of the filled bag. These devices consist of a toggle-joint lever system. They make possible a notable daily production of filled and heat-sealed bags with a single proportioning and heat-sealing station, or with a limited number of stations.

Abstract: Apparatus for the continuous mixing and homogenization of powdered substances, such as powdered milk, with water or other beverages, comprises a hopper (1) with vibrating sieve (2) and a screw (3) situated at the base of the hopper and actuated with variable angular velocity by a motor (4). The powdered substance is transported by the screw to a nozzle (5) opening into a converging-diverging chamber (6) which functions as Venturi tube. The liquid enters from an injection conduit (7) and is mixed with the powder and the mixture is carried to a homogenization turbine (9, 10) from which it is discharged completely homogenized.

Abstract: The invention relates to a tool magazine for automatic tool-changing device, comprising a circular disc mounted for rotation about a pin and comprising on its periphery a series of housings designed to receive the tools whose axes are directed according to the radii of the disc.At least one secondary disc is rotatably mounted co-axially to the main disc on which secondary disc are hingedly mounted, about an axis perpendicular to a radius of the secondary disc, members for supporting the secondary housings designed to receive the tools, the said secondary housings being adapted to be selectively pivotally engaged in an opening provided in the wall of the main disc.The invention is used for storing tools.
