Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
186 words
An apparatus for cultivating microorganisms, comprising: a container for the culture liquid; means to feed the culture liquid into said container; an aerating agent supply means; rotatable ejector means located inside said container for receiving the culture liquid and aerating agent to disperse and intermix the same; means to impart rotation to said ejector means; said container including a diffuser therein adapted to provide a directional flow of the culture liquid to the ejector means, said rotatable ejector means comprising a hollow body located inside the container beneath the diffuser and including a cylindrical-shaped portion for receiving the culture liquid in the container and arranged concentrically below the diffuser in spaced relation therewith, a toroidal portion coupled to said cylindrical portion for receiving the culture liquid from said cylindrical portion, ejectors on said toroidal portion, and a mixing chamber extending in prolongation of each said ejector and having an inlet connected to the aerating agent supply means, said ejectors being mounted on said toroidal portion within the mixing chamber, said mixing chamber extending from the ejectors in a direction opposite to the direction of rotation thereof.
Claim 2
Independent Claim
186 words
An apparatus for cultivating microorganisms, comprising: a container for the culture liquid; means to feed the culture liquid into said container; an aerating agent supply means; rotatable ejector means located inside said container for receiving the culture liquid and aerating agent to disperse and intermix the same; means to impart rotation to said ejector means; said container including a diffuser therein adapted to provide a directional flow of the culture liquid to the ejector means, said rotatable ejector means comprising a hollow body located inside the container beneath the diffuser and including a cylindrical-shaped portion for receiving the culture liquid in the container and arranged concentrically below the diffuser in spaced relation therewith, a toroidal portion coupled to said cylindrical portion for receiving the culture liquid from said cylindrical portion, ejectors on said toroidal portion, and a mixing chamber extending in prolongation of each said ejector and having an inlet connected to the aerating agent supply means, said ejectors being mounted on said toroidal portion within the mixing chamber, said mixing chamber extending from the ejectors in a direction opposite to the direction of rotation thereof.
Claim 3
Dependent Claim
25 words
An apparatus as claimed in claim 1, wherein the ejectors are mounted tangentially on the toroidal portion in the plane of rotation of said ejectors.
Claim 4
Dependent Claim
43 words
An apparatus as claimed in claim 1, wherein the rotatable ejector means includes a rectangular box-shaped duct having outside surfaces cooperating with the toroidal portion to guide the culture liquid to the ejectors, said duct feeding the aerating agent to the mixing chamber.
Claim 5
Dependent Claim
42 words
An apparatus as claimed in claim 1, comprising vertically arranged baffle plates to partition the interior space of the container between the inside surface of the container and the outside surface of the diffuser to accelerate the discharge of spent aerating agent.
Claim 6
Dependent Claim
49 words
An apparatus as claimed in claim 1, comprising vertically arranged baffle plates to partition the interior space of the diffuser to prevent formation of a suction vortex in the culture liquid at the place of its inlet into said hollow body and to make said liquid continuous and uniform.
Claim 7
Dependent Claim
40 words
An apparatus as claimed in claim 1, wherein the culture liquid receiving portion is divided into two zones symmetrical with respect to the axis of rotation of the ejectors so as to provide a bilateral intake of the culture liquid.
