Abstract
Abstract A separating pot for glandless electrical or magnetic drive assemblies includes a pot jacket having a generally tubular body with two ends and a flange portion at one of the two ends, the pot jacket being composed of fiber reinforced plastic with the fiber being wound in alternating layers of circumferential windings and helical windings, and with the flange portion being composed of additional circumferential windings; a bottom member disposed within and closing off the other of the two ends of the pot jacket, the end of the pot jacket being an open end, the bottom member having a generally cup-shaped portion which includes a rim portion surrounding an interior bottom face, the rim portion facing the open end of the pot jacket and extending in an axial direction away from the interior bottom face, the bottom member being in a press fit with the pot jacket and being glued to the pot jacket, the rim portion having a generally conically-shaped interior surface which is enlarged in a direction away from the interior bottom face.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
178 words
A separating pot for glandless electrical or magnetic drive assemblies, comprising: a pot jacket having a generally tubular body with two ends and a flange portion at one of said two ends, said pot jacket being composed of fiber reinforced plastic with the fiber being wound in alternating layers of circumferential windings and helical windings, and with said flange portion being composed of additional circumferential windings; and a bottom member disposed within and closing off the other of said two ends of said pot jacket, said one end of said pot jacket being an open end, said bottom member having a generally cup-shaped portion which includes a rim portion surrounding an interior bottom face, said rim portion facing said open end of said pot jacket and extending in an axial direction away from said interior bottom face, said bottom member being in a press fit with said pot jacket and being glued to said pot jacket, and said rim portion having a generally conically-shaped interior surface which is enlarged in a direction away from said interior bottom face.
Claim 2
Dependent Claim
178 words
A separating pot for glandless electrical or magnetic drive assemblies, comprising: a pot jacket having a generally tubular body with two ends and a flange portion at one of said two ends, said pot jacket being composed of fiber reinforced plastic with the fiber being wound in alternating layers of circumferential windings and helical windings, and with said flange portion being composed of additional circumferential windings; and a bottom member disposed within and closing off the other of said two ends of said pot jacket, said one end of said pot jacket being an open end, said bottom member having a generally cup-shaped portion which includes a rim portion surrounding an interior bottom face, said rim portion facing said open end of said pot jacket and extending in an axial direction away from said interior bottom face, said bottom member being in a press fit with said pot jacket and being glued to said pot jacket, and said rim portion having a generally conically-shaped interior surface which is enlarged in a direction away from said interior bottom face.
Claim 3
Dependent Claim
18 words
A separating pot as defined in claim 1, wherein said bottom member is composed of fiber reinforced plastic.
Claim 4
Dependent Claim
64 words
A separating pot as defined in claim 1, wherein: an adhesive glues said pot jacket and said bottom member together, with said adhesive being hardenable at or above a temperature which corresponds to a temperature of an operating environment in which the separating pot is to be used; and said bottom member including at least one or more circumferential grooves for receiving said adhesive.
Claim 5
Dependent Claim
63 words
A separating pot as defined in claim 2, wherein an adhesive connects said pot jacket and said bottom member together, with said adhesive being hardenable at or above a temperature which corresponds to a temperature of an operating environment in which the separating pot is to be used; said bottom member including at least one or more circumferential grooves for receiving said adhesive.
Claim 6
Dependent Claim
42 words
A separating pot as defined in claim 1, further comprising at least one layer applied to at least one of the exterior and the interior surfaces of said bottom member and said pot jacket, said at least one layer being corrosion resistant.
Claim 7
Dependent Claim
41 words
A separating pot as defined in claim 1, further comprising at least one layer applied to at least one of the exterior and interior surfaces of said bottom member and said pot jacket, said at least one layer being wear resistant.
Claim 8
Dependent Claim
41 words
A separating pot as defined in claim 2, further comprising at least one layer applied to at least one of the exterior and interior surfaces of said bottom member and said pot jacket, said at least one layer being corrosion resistant.
Claim 9
Dependent Claim
41 words
A separating pot as defined in claim 2, further comprising at least one layer applied to at least one of the exterior and interior surfaces of said bottom member and said pot jacket, said at least one layer being wear resistant.
