A method of rapidly applying marks by spraying ink or another marking substance on to articles which move at a high speed or from a marker which is moving rapidly, comprising the step of speeding up the ink to be sprayed by centrifugal acceleration produced by rotation around an axis and guiding the ink during acceleration, so as to produce at least one ink jet along a sweeping path directed, during a fraction of a revolution, towards the article to be marked.

Apparatus for high speed marking of articles

The invention provides, at the end of a pipe which extends a valve being part of an exhausting device for pressure-relieving a pressurized fluid, a nozzle which is exactly at the input of a hood, the convergent portion of said nozzle reducing its exit section so as to make it substantially double the maximum passageway section through the valve.

Discharge conduits of steam generators and the like

The invention comprehends a sound proofed valve for fluid under pressure, comprising a movable obturator for progressively uncovering a series of fluid expansion orifices positioned inside an expansion area, a sound proofing means also positioned inside said expansion area and located opposite fluid jets issuing, in operation of said valve, from said orifices, and a permeable splash guard obstacle placed between said orifices and said sound proofing means and spaced from said sound proofing means.

An arrangement for mounting a cascade of guide vanes or other objects extending across a conduit, characterized in that there is provided within the conduit two longitudinal partitions or plates separated by a small gap, and in that said object is formed in two parts each of which has one end fixed to a wall of the conduit and the other to the longitudinal plate nearest to this fixing point.

Arrangement for mounting guide vanes or other transverse objects inside

In and for an installation comprising a fluid source and a plurality of fluid-using receivers to be fed with fluid from said source, a device for supplying fluid from said source to said receivers independently of one another, said device comprising a fluid manifold connected with said fluid source and branching out into a plurality of fluid emission nozzles having each an outlet opening, and a plurality of fluid-receiving pipes each of which is connected with a corresponding receiver and has an inlet opening located in line with and spaced by a gap from the outlet opening of a corresponding emission nozzle, the cross-sectional area of said inlet opening of a receiving pipe being at the very most equal to the cross-sectional area of said outlet opening of said corresponding emission nozzle.
