An electrodeless fluorescent lighting device is disclosed comprising an outer bulb (22) coated internally with a fluorescent coating (20) which fluoresces when impinged by ultraviolet radiation generated in the bulb by an excitation means (12) which accelerates electrons within a toroidal chamber (14), filled with an ionizable gas which emits ultraviolet radiation under bombardment with electrons....

A suction unit aspirates blood and possibly rinsing fluids from e.g. an operation point, and sources are available for anti-coagulant dilution media. - The blood feeds into a collection container for treatment, and then to a filter for removal of filtrate, including at least part of the dilution medium. Finally, the blood reaches container from which it is returned to the patient. A measurement de...

The present invention relates to a device for hard- boiling eggs without their shells in a microwave. The device comprises a cylindrical beaker which safely accommodates, surrounded by water, a cylindrical cooking vessel with an egg-shaped base into which the egg yolk and white are placed, a dome-shaped lid being provided to close off the said vessel.

The invention concerns a sectioning machine for panels comprising: - one inlet platform (1) for the sustainment of one primary beginning panel (11), to be sectioned, in addition to sectioned strips of second panels (12), obtained from the primary panel (11); - one cutting station (2) designed to simultaneously cut and draw on orthogonal sides between them, first on the primary panel (11) and respe...

The container for glass phials, flacons and the like, comprises a box-type case (1) suited to contain a plurality of phials (2) orderly arranged side by side. Inside the case (1) are devised to be inserted and restrained a plurality of separating elements (3) which define corresponding seatings (4) for housing the phials (2) and which are provided at one end with flaps (6) which are given a transv...
