Abstract
Abstract A facsimile recorder with a web compartment for a roll of moist electrolytic recording paper drawn along a path through a recording zone at the opening of a second compartment for a marking electrode has an apertured non-conductive sheet overlying the opening to prevent contact between the electrode and web outside the recording zone and to pass moisture to the electrode so as to prevent accumulation of recording by-products on the electrode.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
206 words
A facsimile recorder for moist electrolytic recording comprising: a housing including a web compartment for holding a supply of moist web and having an exit, a second compartment having an opening, a closure overlying the web compartment to vapor seal the same and extending over the web path, means for feeding the web on a path from the web compartment across the opening of the second compartment, a first electrode in the second compartment, a second electrode opposed to the just electrode along a recording zone on the web path at the opening of the second compartment, and the second compartment opening substantially to the recording zone, and means to supply moisture to the first recording electrode in the second compartment during feed of the web, so as to prevent the accumulation of recording by-products on the first electrode, the closure and means to supply moisture cooperating to prevent escape of moisture along the web when the web is stopped, and said means to supply moisture comprising a sheet underlying the web path and overlying the second compartment opening substantially to the recording zone, the sheet having apertures therethrough communicating with the second compartment for passing moisture vapor from the recording web to the second compartment.
Claim 2
Dependent Claim

A facsimile recorder for moist electrolytic recording comprising: a housing including a web compartment for holding a supply of moist web and having an exit, a second compartment having an opening, a closure overlying the web compartment to vapor seal the same and extending over the web path, means for feeding the web on a path from the web compartment across the opening of the second compartment, a first electrode in the second compartment, a second electrode opposed to the just electrode along a recording zone on the web path at the opening of the second compartment, and the second compartment opening substantially to the recording zone, and means to supply moisture to the first recording electrode in the second compartment during feed of the web, so as to prevent the accumulation of recording by-products on the first electrode, the closure and means to supply moisture cooperating to prevent escape of moisture along the web when the web is stopped, and said means to supply moisture comprising a sheet underlying the web path and overlying the second compartment opening substantially to the recording zone, the sheet having apertures therethrough communicating with the second compartment for passing moisture vapor from the recording web to the second compartment.
Claim 3
Dependent Claim
119 words
A facsimile recorder for moist electrolytic web recording comprising: a housing including a web compartment for holding a supply of moist web drawn therefrom along a path through a recording zone, the housing including a second compartment having an opening around the recording zone, a marking electrode in the second compartment operative on the web in the recording zone, and means to supply moisture to the electrode and prevent the accumulation of recording by-products on the electrode, said means to supply moisture comprising a sheet underlying the web path and extending over the second compartment opening substantially to the recording zone, the sheet having apertures therethrough communicating with the second compartment for passing moisture vapor to the second compartment.
Claim 4
Dependent Claim
119 words
A facsimile recorder for moist electrolytic web recording comprising: a housing including a web compartment for holding a supply of moist web drawn therefrom along a path through a recording zone, the housing including a second compartment having an opening around the recording zone, a marking electrode in the second compartment operative on the web in the recording zone, and means to supply moisture to the electrode and prevent the accumulation of recording by-products on the electrode, said means to supply moisture comprising a sheet underlying the web path and extending over the second compartment opening substantially to the recording zone, the sheet having apertures therethrough communicating with the second compartment for passing moisture vapor to the second compartment.
Claim 5
Dependent Claim
102 words
A facsimile recorder for moist electrolytic web recording comprising: means to feed a supply of most web along a path through a recording zone, wall means having an opening at the recording zone, a marking electrode operative on the web through the opening, and means to supply moisture to the electrode and prevent the aCcumulation of recording by-products on the electrode, said means to supply moisture comprising a sheet underlying the web path and extending over the opening substantially to the recording zone, the sheet having apertures therethrough communicating through the opening with the electrode for passing moisture vapor to the electrode.
Claim 6
Dependent Claim
102 words
A facsimile recorder for moist electrolytic web recording comprising: means to feed a supply of most web along a path through a recording zone, wall means having an opening at the recording zone, a marking electrode operative on the web through the opening, and means to supply moisture to the electrode and prevent the aCcumulation of recording by-products on the electrode, said means to supply moisture comprising a sheet underlying the web path and extending over the opening substantially to the recording zone, the sheet having apertures therethrough communicating through the opening with the electrode for passing moisture vapor to the electrode.
Claim 7
Dependent Claim
25 words
A recorder according to claim 3 wherein the sheet is of non-conductive material preventing contact of the web and marking electrode outside the recording zone.
Claim 8
Dependent Claim
18 words
A recorder according to claim 3 further comprising a sheet means overlying the paper path and said sheet.
Claim 9
Dependent Claim
56 words
A recorder according to claim 5 comprising a compartment for the web supply wherein the sheet means comprises means for vapor sealing the web compartment and the web path to the recording zone whereby, when the paper is stopped the sheet, sheet means and web prevent moisture loss from the web compartment along the web path.
Claim 10
Dependent Claim
19 words
A recorder according to claim 3 further comprising a second compartment including said wall means and enclosing said electrode.
Claim 11
Dependent Claim
23 words
A recorder according to claim 3 further comprising a second marking electrode opposed to the first said marking electrode along the recording zone.
Claim 12
Dependent Claim
22 words
A recorder according to claim 3 further comprising a base, the feed means, wall means and sheet being supported on the base.
