Abstract
Abstract A basin for use in a sewer system and having a draining device designed as a cover consisting of a housing with a submerged inlet opening and a centrally located outlet opening, the said housing containing an outlet chamber with a circular or helical sidewall along which an inlet tube opens tangentially into the outlet chamber. When the water level in the basin raises, the water flowing into the outlet chamber is caused to circulate in such a manner that it works as a centrifugal brake retarding the water flow.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
Universal basin for use in a sewer system, such as a manhole, gully, sedimentation basin, equalizing basin, and oil and petrol interceptor; comprising a container having an inlet gate, an inlet pipe and a discharge opening; and a draining device mounted in said discharge opening for draining off an approximately constant amount of water through the discharge opening per unit of time, said draining device comprising a cover having spaced end walls and an annular well connecting said end walls defining a hollow housing, a first one of said end walls facing toward said basin having a submerged inlet opening formed therein, the other of said end walls having a centrally located outlet opening communicating with an outlet piping system, an outlet chamber being provided in said housing having a curved side wall portion, an inlet tube extending along said side wall portion and opening tangentially into said outlet chamber; and fastening means being formed along the periphery of said housing for securing said cover to the discharge opening of said basin.
Claim 2
Dependent Claim
172 words
Universal basin for use in a sewer system, such as a manhole, gully, sedimentation basin, equalizing basin, and oil and petrol interceptor; comprising a container having an inlet gate, an inlet pipe and a discharge opening; and a draining device mounted in said discharge opening for draining off an approximately constant amount of water through the discharge opening per unit of time, said draining device comprising a cover having spaced end walls and an annular well connecting said end walls defining a hollow housing, a first one of said end walls facing toward said basin having a submerged inlet opening formed therein, the other of said end walls having a centrally located outlet opening communicating with an outlet piping system, an outlet chamber being provided in said housing having a curved side wall portion, an inlet tube extending along said side wall portion and opening tangentially into said outlet chamber; and fastening means being formed along the periphery of said housing for securing said cover to the discharge opening of said basin.
Claim 3
Dependent Claim
62 words
Universal basin as claimed in claim 1, said housing having an inlet chamber, a partition separating said inlet chamber and said outlet chamber, an inlet strainer interconnecting said chambers, A bottom chamber forming a trap, and said inlet tube connecting said bottom chamber and said outlet chamber, said inlet tube having a discharge end forming the inlet opening to said outlet chamber.
Claim 4
Dependent Claim
58 words
Universal basin as claimed in claim 1, including a groove in the bottom of said basin in parallel with the plane of the draining device, a protective cover having submerged openings being mounted in said groove so as to cover the draining device while simultaneously forming a sedimentation- and clarification chamber between said device and the protective cover.
Claim 5
Dependent Claim
22 words
Universal basin as claimed in claim 3, said groove including hinge means for hinged connection of said protective cover to said basin.
Claim 6
Dependent Claim
79 words
Universal basin as claimed in claim 1, comprising a conical annular groove encompassing said discharge opening and tapering in relative to the direction of installation of said draining device in said openings, a sealing and locking ring engaged in a recess in said groove retaining said draining device in said opening; and a removal ring fastened to the lower end of said sealing and locking ring facing said basin adapted to facilitate removal of the latter from said groove.
Claim 7
Dependent Claim
168 words
Universal basin as claimed in claim 2, said end wall facing the basin forming a protective cover, said inlet opening in said end wall being at its bottom edge that is submerged at lowest water level, a vertical venting tube at the basin side of said end wall, having bottom end thereof open to the basin at a point proximate the center of said end wall and the top end of said venting tube opening into the upper end of said inlet chamber, a downwardly directed outlet tube communicating with the centrally located outlet opening in said other end wall, said outlet chamber having a helical side wall and forming a centrifugal brake, said inlet chamber, bottom chamber and inlet tube together forming a trap, and said outlet tube and the inlet tube of the centrifugal brake forming a syphon system in which the lower end of the inlet tube projecting into the bottom chamber is located at a level above the bottom end of the outlet tube.
Claim 8
Dependent Claim
37 words
Universal basin as claimed in claim 6, comprising an air stabilizer in said outlet chamber forming said centrifugal brake, said air stabilizer being in the shape of a projection directed radially inwardly from the helical side wall.
Claim 9
Dependent Claim
20 words
Universal basin as claimed in claim 6, comprising an inlet strainer located between said inlet chamber and said bottom chamber.
Claim 10
Dependent Claim
66 words
Universal basin as claimed in claim 1, comprising an emergency overflow including a substantially vertical pipe in said basin, the upper end of said pipe opening proximate the top of the basin, and a combined basket and ball float supported on the upper end of, and said pipe, the lower end of the pipe opening on the side of the draining device remote from the basin.
Claim 11
Dependent Claim
67 words
Universal basin as claimed in claim 1, said housing being an undivided double conical housing, a plurality of submerged inlet openings being provided in the bottom part of one housing end wall, an internal inlet tube extending tangentially to the housing communicating with said inlet openings, and an outlet tube directed downwardly from the discharge opening being centrally located in the other end wall of said housing.
