  • Centralized control device for controlling the application of voltage to a load provided with a power factor correction capacitor
    Patent number: 7288904
    Abstract: A centralized device for supply voltage control of a load with power factor correction condensers for lighting engineering applications has an array converter for obtaining a portion of power, with a plurality of switches located between the network sinusoidal supply and the load. The centralized device has controlling and regulating means for managing both the activation and deactivation states of the switches of the array converter so as to avoid sudden voltage changes across the load and provide for control of the load voltage.

  • Hydraulic nozzle used especially as a shower attachment, with sprayer comprising a chamber for mixing toilet products in tablet form with water
    Patent number: 5957387
    Abstract: Nozzle (10) for showers with a sprayer (30) comprising a mixing chamber (51) in which is placed a soluble toilet product in tablet form (80), replaceable, said chamber being connected to said nozzle (10) by a pair of threads on the sides which, on rotating said sprayer (30) in one direction or the other, cause the chamber to move axially between a washing position when water passes through said mixing chamber (51) and dissolves the toilet product (80), and a rinsing position when the water passes through an annular chamber (32) that surrounds said mixing chamber (51).
