Abstract
Abstract In apparatus wherein a moving wire is drawn through a reaction tube and a material is deposited thereon, a reactor seal is provided to isolate the reactant gases within the tube from the surrounding atmosphere. The reactor seal comprises a fitting having a generally vertically disposed passageway therethrough within which is disposed a pair of aligned orificed inserts through which the wire is drawn. A pool of liquid metal is supported on the lower insert at the orifice thereof by surface tension forces. Both inserts have downwardly converging inner walls leading to their orifice to facilitate threading.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
In a vertically arranged reactor vessel wherein a vapor deposition is effected on a moving filamentary substrate, a reactor seal comprising: a liquid sealant comprising a pool of mercury disposed at an end of the vessel and through which the substrate moves; an end fitting forming an end closure for the reactor vessel, the fitting having a generally vertically disposed passageway therethrough through which the substrate is drawn and the fitting supporting said liquid seal in said passageway; and a filamentary thread guide received in said passageway above said liquid seal and having a downwardly convergent passageway therethrough said guide comprising a baffle means to substantially prevent vaporization loss of said mercury pool.
Claim 2
Dependent Claim
113 words
In a vertically arranged reactor vessel wherein a vapor deposition is effected on a moving filamentary substrate, a reactor seal comprising: a liquid sealant comprising a pool of mercury disposed at an end of the vessel and through which the substrate moves; an end fitting forming an end closure for the reactor vessel, the fitting having a generally vertically disposed passageway therethrough through which the substrate is drawn and the fitting supporting said liquid seal in said passageway; and a filamentary thread guide received in said passageway above said liquid seal and having a downwardly convergent passageway therethrough said guide comprising a baffle means to substantially prevent vaporization loss of said mercury pool.
Claim 3
Dependent Claim
180 words
In a vertically arranged reactor vessel wherein a vapor deposition is effected on a moving filamentary substrate, a reactor seal comprising: a liquid sealant comprising a pool of mercury disposed at an end of the vessel through which the substrate moves; an end fitting forming an end closure for the reactor vessel, the fitting having a generally vertically disposed passageway therethrough through which the substrate is drawn; a first insert disposed in said fitting passageway, said insert having a generally vertical passageway therethrough, said passageway terminating in an orifice small enough to retain said liquid sealant thereon through surface tension forces and large enough to allow free passage of said filamentary substrate therethrough; said liquid sealant being supported by said first insert; a second insert disposed in said fitting passageway above said first insert, said second insert having a generally vertical passageway therethrough concentric with said fiRst insert passageway, said second insert passageway terminating in an orifice small enough to substantially prevent vaporization loss of said liquid sealant and large enough to allow free passage of said filamentary substrate therethrough.
Claim 4
Dependent Claim
180 words
In a vertically arranged reactor vessel wherein a vapor deposition is effected on a moving filamentary substrate, a reactor seal comprising: a liquid sealant comprising a pool of mercury disposed at an end of the vessel through which the substrate moves; an end fitting forming an end closure for the reactor vessel, the fitting having a generally vertically disposed passageway therethrough through which the substrate is drawn; a first insert disposed in said fitting passageway, said insert having a generally vertical passageway therethrough, said passageway terminating in an orifice small enough to retain said liquid sealant thereon through surface tension forces and large enough to allow free passage of said filamentary substrate therethrough; said liquid sealant being supported by said first insert; a second insert disposed in said fitting passageway above said first insert, said second insert having a generally vertical passageway therethrough concentric with said fiRst insert passageway, said second insert passageway terminating in an orifice small enough to substantially prevent vaporization loss of said liquid sealant and large enough to allow free passage of said filamentary substrate therethrough.
Claim 5
Dependent Claim
21 words
The invention of claim 2 wherein the passageways in said first and second inserts are formed by downwardly converging inner walls.
