  • Small-size hermetic helium 3 refrigeration stage
    Patent number: 4300360
    Abstract: The invention provides a small-size hermetic refrigeration stage containing helium 3 and easily incorporated in a conventional helium 4 metal cryostat.The stage consists essentially of a metallic enclosure containing a certain volume of helium 3 and having a first receptacle constituting the pumping chamber and consisting a mass of an adsorbing body for the helium 3 at a very low temperature, a second receptacle constituting a condenser for the cooled helium 3 and a duct.The stage of the invention is particularly suited for maintaining the sensitive element of an infrared detector at a temperature of less than 1.degree. K.

  • Portable helium 3 cryostat
    Patent number: 4136526
    Abstract: The invention relates to apparatus maintaining extremely low and constant temperatures. The helium 3 (He.sup.3) cryostat is disposed inside a portable helium 4 (He.sup.4) cryostat which is constituted by a Dewar jar 2 with helium 4 at 6. The helium 3 cryostat comprises an evaporation chamber 11, a reservoir 13, an adsorption chamber 16 with an adsorbent 17, two pipes 15 and 18 and a valve 20. Particular applications in conjunction with a bolometer, the sensitive element of which is shown at 26.

  • Method of treatment of an oxidizable material by a biochemical process
    Patent number: 4100062
    Abstract: The present invention relates to a method of and an installation for the treatment of a material oxidizable by a biochemical process, in which at least one oxygenation process is applied to a mixture comprising water, the oxidizable material and a biomass, this oxygenation process comprising at least the three following operations:(1) In an oxygenation zone substantially isolated from the ambient air, establishing a biochemical oxidation system comprising firstly a liquid mass of the mixture to be treated, limited by the lower portion of the oxygenation zone, and secondly a gaseous atmosphere comprising oxygen, surmounting the liquid mass and limited by the upper portion of the oxygenation zone;(2) Circulating in the oxygenation zone by means of a mechanical oxygenation device, one of the constituents of the biochemical oxidation system, namely the portion of the liquid mass and the portion of the gaseous atmosphere, each limited by the portion of the oxygenation zone, in contact with each other;(3) Supplying
