Abstract: This invention relates to a device for the activation of perborate in washing machines, said device comprising a cup (2, 8) for activating perborate which is fed by a perborate metering device (1) or may also lack such device, and is connected to the washing tub (6) through a conduit (7) and is supplied with water through the conduit (9) for the supply of water from the water main, or a conduit (18) arranged as a by-pass in said conduit that supplies water from the water main, or through a conduit (19) connected to the bottom of the washing tub (6); said device also comprising an electric resistance (3) for heating water contained in said cup (2, 8) or at a point upstream said cup, and means (4) that detect the temperature inside said cup (2, 8).

Abstract: A new configuration of the electrodes of a transverse discharge pumped gas laser is disclosed, in which the electrode connected to ground and the electrode connected to the main condenser bank are placed on the same plane so as to face a third electrode connected to a high impedance. There are two distinct discharge regions, one of which is the back path of the current passing through the first discharge region.

Abstract: A FIR Laser cavity comprising a pair of concentric tubes of heatproof dielectric, a pair of nozzles intended for circulating within the space between said pair of tubes a refrigerating and thermally stabilizing fluid; a pair of laser heads disposed at the two ends of said tubular assembly which heads are provided with optical elements; a differential thread sleeve mounted concentrically with said tubes and intended for obtaining the longitudinal micropositioning of one of said heads with respect to one another; two series of three screws which are mounted with a starlike symmetry on said heads and intended for allowing a fine adjustment of the optics carried by said heads along two axes perpendicular to one another and with respect to the geometrical axes of said tubes by means of the elastic deformation of an O ring which is interposed between each head and the tubular body and an output optics carrier and comprising either a reflector and a window for the hermetic seal, or by the reflector alone, which is g
