Abstract: A sterile pharmaceutical composition having as its active principles piperacillin sodium and tazobactam sodium of substantially the same density, mixed with sodium bicarbonate. The mixture is soluble in water to give injectable reconstituted solutions having high stability with time.

Abstract: Mixtures of at least two active principles, of which at least one is the sodium salt, are precipitated from an organic solution containing the same active principles in salified or non-salified acid form.

Abstract: Crystalline acetonitrile solvate of cefuroxime acid, useful for preparing the antibiotic cefuroxime sodium salt.

Abstract: A lance with swinging head (10) for high pressure cleaning equipments, includes: a tubular body (12) connected to the flexible duct coming out of said equipment on one side and,, to the other side, to a cylindrical shaped body (16) and to a nozzle (18) provided with an axial hole (42) with an end throat (42?). The body (16) is provided with an axial drilling with differentiated and increasing diameters starting from its rear end connected to the tubular body (12) towards the opposite front end (22) facing the nozzle (18) and defines, in correspondence with the front end (22) facing the nozzle (18), an annular and shaped seat housing a substantially hemispherical head (34) integral with the same nozzle, partly delimited by a ring (20) fastened to the front end (22) of the body (16).

Abstract: A lance (10) with multiple movement dispenser nozzle (44) includes a tubular body (12) provided with an axial duct (20) for the passage of the pressure water fluid; a shaped sleeve (14) matched at the front end of the tubular body (12); a rotor or rotating element (16) housed into the shaped sleeve (14), and a plate-shaped element (18) supported by a plate (22) associated to the duct (20). On the front part facing the rotor (16), the plate-shaped element (18) is provided with a shaped central recess 26 which circularly extends and having an undulated external profile from which a plurality of additional recesses (32) radially extend. The opposite rear part of the plate-shaped element (18) is provided with an integral tang (24) engaging with the plate (22).

Abstract: A method for decontaminating the copper surfaces (e.g. circuits) of an electronic card from copper salts which can be formed after the soldering of the electronic components onto the substrate employing a water free solution which comprises an alcohol and at least one neutral ammonium salt of an organic acid.
