Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
153 words
A rectilinear plate type condenser having a condensing and heat transmitting plate surface along which a steam condensate flows downwardly in the form of a film, said plate surface having a plurality of vertically spaced, horizontal top portions formed therein, each top portion being connected to the next succeeding downwardly spaced top portion by a downwardly and outwardly inclined surface portion thereby forming a step portion at the lower end of each downwardly and outwardly inclined surface portion along said plate surface, said downwardly and outwardly inclined surface portions being horizontally spaced whereby the condensate formed on each inclined surface portion of said plate surface will freely fall from the lower end of each downwardly and outwardly inclined surface portion downwardly to the next step portion at the lower end of the next succeeding downwardly and outwardly inclined surface portion until the collected condensate reaches the lowermost end of the heat transmitting surface.
Claim 2
Dependent Claim
153 words
A rectilinear plate type condenser having a condensing and heat transmitting plate surface along which a steam condensate flows downwardly in the form of a film, said plate surface having a plurality of vertically spaced, horizontal top portions formed therein, each top portion being connected to the next succeeding downwardly spaced top portion by a downwardly and outwardly inclined surface portion thereby forming a step portion at the lower end of each downwardly and outwardly inclined surface portion along said plate surface, said downwardly and outwardly inclined surface portions being horizontally spaced whereby the condensate formed on each inclined surface portion of said plate surface will freely fall from the lower end of each downwardly and outwardly inclined surface portion downwardly to the next step portion at the lower end of the next succeeding downwardly and outwardly inclined surface portion until the collected condensate reaches the lowermost end of the heat transmitting surface.
Claim 3
Dependent Claim
23 words
A rectilinear plate type condenser in accordance with claim 1, wherein the surface of the outwardly inclined surface portion is smooth and uninterrupted.
Claim 4
Dependent Claim
48 words
A plate type condenser in accordance with claim 1, wherein each downwardly and outwardly inclined surface portion is provided with a plurality of laterally spaced, vertically disposed grooves, the free lower end of each groove terminating in a projection portion to facilitate the collection and dropping of condensate.
