Abstract
Abstract A tank for processing photographic materials has an opening which is closed with a movable cover provided with an inlet and outlet for water. A hose is connectable with a source of water and a releasable connecting element connects the hose with the inlet in the cover. The connecting element has a flow passage for the water and is at least in part transparent so that the interior of the passage can be observed. Also, the connecting element has a port which communicates with the flow passage and which can be partly or completely closed at the will of the user.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
180 words
A receptacle, particularly a tank for processing of photographic material, comprising a vessel having an opening; a removable cover for said opening and provided with an inlet aperture and an outlet aperture; a conduit adapted to be connected to a source of liquid; and a connecting element for connecting said conduit with said inlet aperture, said connecting element comprising an outer portion having a first passage therethrough and adapted to communicate with said inlet aperture, an inner tubular portion received in and defining with part of said first passage an annular clearance and having a second passage therethrough which communicates with said first passage upstream of said inlet aperture, one of said passages communicating with said conduit so as to receive liquid therefrom, said outer portion having at least one intermitently closeable part therein communicating with the other of said passages and with the ambient atmosphere for allowing air to be aspirated through said other passage and said port when flowing liquid fills at least part of said clearance and said first passage intermediate the inlet aperture and the clearance.
Claim 2
Dependent Claim
180 words
A receptacle, particularly a tank for processing of photographic material, comprising a vessel having an opening; a removable cover for said opening and provided with an inlet aperture and an outlet aperture; a conduit adapted to be connected to a source of liquid; and a connecting element for connecting said conduit with said inlet aperture, said connecting element comprising an outer portion having a first passage therethrough and adapted to communicate with said inlet aperture, an inner tubular portion received in and defining with part of said first passage an annular clearance and having a second passage therethrough which communicates with said first passage upstream of said inlet aperture, one of said passages communicating with said conduit so as to receive liquid therefrom, said outer portion having at least one intermitently closeable part therein communicating with the other of said passages and with the ambient atmosphere for allowing air to be aspirated through said other passage and said port when flowing liquid fills at least part of said clearance and said first passage intermediate the inlet aperture and the clearance.
