Definitions

  • evaporator of the character commonly employed in vaporizing liquid oxygen.
  • evaporator is seen to comprise a relatively thick-walled outer vessel commonly referred to as a pressure vessel" and contains a relatively thin-walled inner vessel or basket supported in the outer vessel in a manner which provides a relatively narrow clearance space between the inner and outer vessels.
  • the space within the inner vessel preferably communicates with the clearance space between the inner an outer vessels by means of a ring of holes dis sed in the wall of the inner vessel below its upper edge.
  • the device for preventing overfilling, and consequently the overflow of liquid into the clearance space is shown inserted within the filling opening 1 and comprises a snugly fitted thinwalled cylindrical tube 2 in which a filling conduit or pipe 3 is concentrically disposed but out of contact with tube 2.
  • the lower end of pipe 3 is made to depend into the pressure vessel a substantial distance below the liquid level in-- tended to be maintained within the pressure vessel.
  • the intended liquid level is indicated in the drawing by a line at 4 and the lower open end of the tube 2 is arranged to terminate a short distance above the liquid level 4.
  • the filling conduit is connected in the usual manner with a supply of liquid oxygen, while the annular space about the filling conduit within the tube 2 is vented to the atmosphere.
  • the modified form of device shown in Fig. 2 consists of a thin walled cylinder 2 inserted into the filling opening'l of the evaporator.
  • the cylin der 2 has a pierced part 5 with a sumcient amount of openings for allowing an escape of the gases which are developed during filling.
  • the filling tube 3 projects into this pierced part of the inserted cylinder to such an extent that the outflow ot the gases takes place without any liquid from the entering jet being forced out by and along with said gas. It then however the liquid begins to rise this tree sectional area of the pierced part decreases as the level rises until the escaping stream of gas takes liquid from the level and iorces it out into the atmosphere.
  • the bottom of the pierced part is also con stricted and serves the purpose to prevent small 7 parts of the installation, such asnuts, small spanners and the like, from falling into the liquid container and to prevent it from being damaged thereby.
  • a device for preventing the overfilling of warm converters when filling the same with liquefled gases comprising the combination with an outer wall of such converter having a filling opening, of a thin-walled tube vented to the atmosphere snugly fitted into said opening and depending into said converter to a point short of the desired liquid level, and a filling conduit disposed within said snugly fitted tube and on contact therewith and extending into said converter to a point below the desired liquid level and adapted to communicate exteriorly of said converter with means for supplying liquid.
  • a device for preventing the overfilling of warm converters for liquefied gases having a pressure vessel, comprising the combination with a wall of said pressure vessel having a filling opening, of a thin-walled cylindrical tube vented to the atmosphere snugly fitted into said opening and depending into said pressure vessel, said tube being arranged to communicate with the space in the warm converter above the intended liquid level, and a filling conduit disposed concentrically within but out of contact with said snugly fitted tube and extending into said pressure vessel to a point below the intended liquid level and adapted to be connected with means on the exterior of said pressure vessel for supplying liquid.
  • a device for preventing overflow into the space between the basket and pressure vessel of warm converters when filling the same with liquefied gases comprising the combination with a wall of the pressure vessel having a filling opening, of a thin-walled tube snugly fitted within said filling opening depending into said pressure vessel and formed with a pierced portion at its lower end communicating with the interior of said pressure vessel at a point above the intended liquid level, said snugly fitted tube being provided with connections on the exterior of said pressure vessel for venting the same to the atmosphere, and a filling conduit disposed within but out of contact with said snugly fitted tube and spaced away from thewalls thereof and depending into said pressure vessel to a point below the intended liquid level, said pierced portion being constricted about said filling conduit for preventing the entry by way thereof of extraneous objects into said pressure vessel.
