Abstract
Abstract In an apparatus for preparation of high-melting-point high-toughness metals by reduction of chlorides thereof with an active metal which comprises a heatable and tightly closable reaction chamber, an evacuable and coolable condensation chamber for separating the unreacted active metal and the formed chloride of the active metal from the formed object metal and an intermediate connecting section for communicating and cutting off the two chambers, the improved apparatus which is characterized in that it comprises a seal pot closing means having a funnel and a pot which is closed by introducing a melt of a fusible and vaporizable material and solidifying it therein, is disclosed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
An apparatus for the preparation of high-melting-point high-toughness metals by reduction of chlorides thereof with an active metal which comprises a heatable and tightly closable reaction chamber, an evacuable and coolable condensation chamber for condensing the unreacted active metal and the formed chloride vaporized in the reaction chamber to separate these from the formed object metal, and an intermediate connecting section for communicating and sealing off the two chambers, wherein said apparatus comprises a seal pot closing means having a funnel provided in the intermediate connecting section and pot for fusible and vaporizable sealing material which receives the lower pipe of the funnel and the heating means for melting and vaporizing the fusible and vaporizable material, and wherein the pot of the seal pot structure is provided with a conduit with a valve means for the fusible and vaporizable material.
Claim 2
Independent Claim
140 words
An apparatus for the preparation of high-melting-point high-toughness metals by reduction of chlorides thereof with an active metal which comprises a heatable and tightly closable reaction chamber, an evacuable and coolable condensation chamber for condensing the unreacted active metal and the formed chloride vaporized in the reaction chamber to separate these from the formed object metal, and an intermediate connecting section for communicating and sealing off the two chambers, wherein said apparatus comprises a seal pot closing means having a funnel provided in the intermediate connecting section and pot for fusible and vaporizable sealing material which receives the lower pipe of the funnel and the heating means for melting and vaporizing the fusible and vaporizable material, and wherein the pot of the seal pot structure is provided with a conduit with a valve means for the fusible and vaporizable material.
Claim 3
Dependent Claim
26 words
The apparatus as recited in claim 1, wherein the pot of the seal pot closing means is provided with a drain duct with a valve means.
Claim 4
Dependent Claim
15 words
The apparatus as recited in claim 2, wherein the pot has an oblique plane bottom.
Claim 5
Dependent Claim
25 words
The apparatus as recited in claim 3, wherein the drain duct is provided in a straight line with the oblique bottom plane of the pot.
Claim 6
Dependent Claim
24 words
The apparatus as recited in claim 4, wherein the valve means consists of a bush provided in the tapping pipe and a water-cooled plug.
Claim 7
Dependent Claim
185 words
The apparatus as recited in claim 4, wherein the intermediate connecting section has a flange outwardly extending from the bottom edge thereof, a short cylindrical wall concentric with the intermediate connecting section per se and smaller than said flange per se in diameter is provided on the upper surface of said flange, said wall is provided with a flange outwardly extending from the top edge thereof, the internal container comprises a cylindrical member and a base plate with at least one perforation and supporting legs, the cylindrical member is provided with a flange outwardly extending from the top edge thereof, the retort is also provided with a flange outwardly extending from the top edge thereof, and the flange of the retort, the flange of the cylindrical member of the internal container and the flange of the short wall of the intermediate connecting section are laid one over another with a gasket therebetween and fixed together, whereby the bottom flange of the intermediate connecting section is inserted in the cylindrical member and the outward periphery of the flange reaches the inside wall of the cylindrical member.
Claim 8
Dependent Claim
161 words
The apparatus as recited in claim 4, wherein the intermediate connecting section has a flange outwardly extending from the bottom edge thereof, a short cylindrical wall concentric with the intermediate connecting section per se and smaller than said flange per se in diameter is provided on the upper surface of the flange, said wall is provided with a flange extending from the top edge thereof, the internal container comprises a cylindrical member and a base plate with at least one perforation and supporting legs, the retort is provided with a flange outwardly extending from the top edge thereof, and the flange of the short wall of the intermediate connecting section is laid over the flange of the retort with a gasket inserted therebetween and fixed together, whereby the bottom flange of the intermediate connecting section is inserted into the retort and rests on the top edge of the cylindrical member of the internal container and reaches inside surface of the retort.
