Abstract: A baby rocking device, adapted to impart a reciprocating cycling rocking movement to a perambulator, push-chair or the like, comprising a single roller, having an electric motor arranged inside the roller, the roller configured for rolling on a floor. The roller includes an inner non-rotating core having two ends portions projecting from opposite ends of the roller and connected to two receiving and supporting members configured for receiving two respective wheels of the perambulator or push-chair, so that the perambulator or push-chair is placed astride the single roller, and a cylindrical outer shell for contact with the floor, which is rotatably mounted on the inner core. The electric motor is carried by the inner core and is provided for actuating the rotation of the outer shell alternately in two opposite directions of rotation, so as to cause rolling of the single roller on the floor alternately in two opposite directions.

Abstract: An apparatus for selecting products on the basis of their composition via X-ray fluorescence spectroscopy includes an X-ray source that emits an X-ray beam towards a product sample, and a particle detector for receiving an X-ray beam diffused by the product sample and generating a signal received that can be analysed to determine a chemical composition of the product sample and selecting a type of product corresponding to said chemical composition of the product sample. The apparatus includes a first vacuum chamber located between an output of the apparatus facing the product sample and the X-ray source, and a second vacuum chamber located between the output of the apparatus facing the product sample and the detector. The apparatus also includes an optical module with polycapillary lens located downstream of the X-ray source, which is configured for focusing the X-ray beam and is associated in a vacuum-tight way to the first vacuum chamber.

Abstract: A copper metal alloy, for use in making elements for promoting and/or stimulating vital energy comprises between 60% and 70% in weight of copper (Cu), between 16% and 24% in weight of silver (Ag), between 3% and 6% in weight of zinc (Zn), between 3% and 6% in weight of manganese (Mn) and between 0.5%> and 6%> in weight of germanium (Ge). Tin (Sn) in percentage comprised between 3% and 6% can also be provided for. Platinum (Pt) can also be provided for between 0.1% and 5% in weight. The alloy is used for making for example sheets in form of plates or strips which are associated to articles of various types.

Abstract: A wrist belt or bracelet having a timepiece function, comprises an annular plastic material body within which a flexible material strip which carries display means, an electronic control unit and an electrical power supply battery, is embedded. The display means and the electronic control unit are provided for displaying the time through numbers or symbols which are lighted along the abovementioned strip.
