Abstract

108,590. British Thomson - Houston Co., (General Electric Co.). Oct. 18, 1916. Vacuum obtained by condensation of vapour.- Relates to improvements upon the means for exhausting by means of a current of mercury vapour described in Specification 105,357. Within a cylindrical metal vessel 1, Fig. 1, there is an upright conduit 3, surmounted by an open cap 4 conducting vapour from mercury 5 heated by an electric coil 6. Passage of the vapour through the cap draws air downwards through a pipe 9 communicating with the vessel to be exhausted, condensation occurring upon the walls of the cylindrical vessel, which are cooled externally by means of a cooling-coil 11 soldered to the wall, and the condensed vapour returning under the direction of a baffle 15 through apertures 17, 14 and grooves 18 to the main body of the liquid. A rough pump withdraws the air by a connexion 13. Tn a modified form the mercury-vapour uptake is bent over through 180 degrees into a somewhat similar but jacketed condenser, having a trapped communication with the vessel to be exhausted, this passage being subdivided by diaphragms so as to impede the flow of any mercury vapour towards the vessel.
