Patent number: 9599390Abstract: A device for producing artificial snow includes: elements (100) for producing a central jet (101) consisted by a first fluid chosen among air or water; elements (110) for producing a peripheral jet (111) consisted by a second fluid chosen among water or air and different from the first fluid; and nucleation elements (120) for the production of at least one nucleation jet (121). The elements for producing the central jet and the elements for producing the peripheral jet are arranged in such a manner that the opposite contours (103, 114) of their respective jets each define a generating line, which opposite generating lines extend parallel or at least approximately parallel to each other; moreover, the nucleation elements (120) are distributed over the external periphery of the elements (110) for producing the peripheral jet (111).Type: GrantFiled: August 25, 2014Date of Patent: March 21, 2017Assignee: TECHNOALPIN FRANCE SASInventors: Michel Galvin, Eric David, Karlheinz Terrabona

Patent number: 8292261Abstract: A water and/or air dispenser for snowmaking system includes water and/or air supplying ducts and is equipped with at least one valve (9) associated with an electric actuator (10), the actuator (10) being connected to an electric power source (12, 19) and associated with its own management unit (11) to ensure the operation of the valve (9) between the open and closed configurations thereof. The dispenser is associated with security elements able to cause the valve (9) to be positioned in a known security configuration, for example tightly closed, in case of voltage cut-off at the electric source (12, 19), the security elements being integrated and including a capacitor-type electric unit (16), connected to the electric power source and to the actuator (10), the capacitor unit being able to store, and then return, a quantity of energy necessary for complete actuation of the valve, to implement the security elements.Type: GrantFiled: November 28, 2008Date of Patent: October 23, 2012Assignee: Johnson Controls Neige SASInventors: Damien Landreau, Eric David, Pierrick Jouneau, Michel Galvin
