According to the invention, the two-axes-compensation and anticollision device comprises a structure (11, 12, 14, 14', 15, 15.1, 16) for connection between a horizontal plate (Bl) fixed to a manipulator arm (B) and a horizontal, plate (B2) for attachment of the operating tool (P) having a variable-geometry articulated parallelogram configuration, under the action of forces a component of which is directed along a cartesian axis in the horizontal plane (X, Y), and controlled translational sliding mobility, under the action of forces a component of which is directed according to the other cartesian axis in the horizontal plane (Y, X), so as to exceed, by means of variation of geometrical configuration and/or by means of controlled mobility, a physical barrier with respect to which said tool operatively interferes, if the order of the interference between said parts falls within a range of predetermined dimensional tolerances with respect to the cartesian axes (X, Y) in the horizontal plane. Spring means (15.2, 17, 17.1, 17.2, 18, 19; 16, 16.1, 16.2, 21, 22) for compensation of said variation of geometrical configuration and/or of said controlled mobility, after said physical barrier has been exceeded, automatically restore the initial geometry and arrangement of said structure.

The present invention relates to a machine for triturating composite materials, particularly for triturating solid urban waste, which comprises a shredding apparatus (4) that is in turn composed of a cutting element (7) provided with multiple blades (9) arranged side by side along an axis, of means for actuating the blades with a rotary motion about the axis, and of a complementary cutting element (16) which is laterally adjacent to the cutting element. The complementary cutting element (16) cooperates with the cutting element in shredding the material conveyed between the cutting element and the complementary cutting element, and is movable away from the cutting element to allow material that withstands the action of the blades (9) of the cutting element to pass between the cutting element (7) and the complementary cutting element (16).

A positive-displacement pump for fluid products, in particular paints, colorants and the like, comprises a pump body (2) in which there is formed a pumping chamber (3), in which a piston (5) is mounted for sliding and is controlled so as to advance and withdraw in order to vary the useful volume of the pumping chamber (3). The pumping chamber (3) is placed in communication with a pumping pipe (38) leading into an upper region (42) which is located at the highest location of the pumping chamber (3).
摘要:
A dispensing machine for producing paint samples including a main delivery unit for delivering at least two main paints via at least two main pumps, and a colourant delivery unit for delivering a plurality of colourants via a corresponding plurality of colourant pumps. The main pumps are volumetric pumps each having a first swept volume. The colourant pumps are volumetric pumps each having a second swept volume, less than the first swept volume. The machine additionally includes at least one magazine for empty containers. The machine can include at least one magazine for container cover elements. A handling system conveys a container from the container magazine to a common delivery zone and from there to a capping station.
摘要:
The invention relates to a preparation process of a flame retardant composition made from brominated bismuth and/or antimony compounds complexed with melamine, in which melamine, at least one between the bismuth carbonate and antimony sesquioxide, hydrobromic acid in aqueous solution are placed in contact with each other so as to trigger chemical reactions which lead to the formation of a complex of brominated bismuth or brominated antimony with melamine and melamine bromohydrate. The reagents are placed in contact in the presence of at least one reaction carrier defined by at least one compound chosen from the group consisting of melamine, melamine phosphate, melamine polyphosphate, ammonium phosphate, ammonium polyphosphate, triphenylphosphate,graphite, silica, lignin, coke and compounds containing triazine rings condensed or linked by -NH groups. The reaction carrier is not involved in the reactions. There are no polymeric compounds in quantities such as to create a polymer matrix. The reagents being introduced into the reactor in an amount defined by the stoichiometric ratios of said reactions. The reaction carrier is introduced into the reactor in an amount defined with respect to the total weight of the reagents so that it can perform a modulator function.

A positive-displacement pump for fluid products, in particular paints, colorants and the like, includes a pump body in which there is formed a pumping chamber, in which a piston is mounted for sliding and is controlled so as to advance and withdraw in order to vary the useful volume of the pumping chamber. The pumping chamber extends in accordance with a longitudinal axis which is inclined, in a non-vertical manner, with respect to a horizontal plane and having an upper region which is positioned at a greater height with respect to a horizontal plane and in the region of which the pumping chamber is placed in communication with at least one intake pipe of a fluid product.
