  • Device for producing a cold treatment gas
    Patent number: 4698976
    Abstract: A device is provided for producing a cold treatment gas from nitrogen and air for the cryotherapy of rheumatic diseases in which liquid nitrogen vaporizes and is mixed in the desired ratio with the dry air which is at a higher pressure. The device includes a vessel for the storage of the liquid nitrogen which has a capacity for carrying out at least one or more treatments. Heat exchanging apparatuses are installed in the vessel for channeling a portion of the air which is at a higher pressure.

  • Guidance device for a laser beam for three-dimensional machining of workpieces
    Patent number: 4694139
    Abstract: In a guidance device for a laser beam (17) repeatedly reflected at 45.degree. mirrors at least six controllable movement axes (X, Y, Z, 4, 5, 7) are provided, of which two movement axes (5,7) are horizontal swiveling axes (11, 14), whereby the one swiveling axis (14) is assigned to the laser head (15). It can be achieved not only with two-dimensional cuts but also with three-dimensional cuts by appropriate adjustment of the swiveling angles (.alpha.,.beta.) at the swiveling axes (11, 14) and by a sufficient distance between the two swiveling axes (11, 14), that the point of intersection (27) on the workpiece (26) is always located vertically under the Z-movement axis, whereby the movement programming of the device is simplified. By adjustment of equal swiveling angles (.alpha.,.beta.) simplified circular arc cuts can be performed by rotation around only one movement axis (4) at horizontal workpieces.

  • Procedure for creating an inert gas atmosphere with constant composition of nitrogen and carbon dioxide in a refrigerated container
    Patent number: 4537043
    Abstract: An inert gas atmosphere of nitrogen and carbon dioxide is created in a refrigerated container having a diesel engine. A lower oxygen content is maintained by an oxygen limit control while the nitrogen is led into the interior of the container from a gas bottle connected with the container when the predetermined oxygen limit value is exceeded. While the inert gases are being supplied, a constant flow of cold gaseous nitrogen is produced by an electrical evaporator in the liquid nitrogen storage tank and connected to the generator of the diesel engine while carbon dioxide is removed from the gas bottle, heated, released to a constant pressure and fed into the container via throttle points constituting a parallel-switched group of such throttle points which can be individually activated.
