Abstract
Abstract An irradiator apparatus designed to perform a sterilization treatment or like process on waste material especially in the liquid state such as sewage or general industrial waste wherein a radiation source in the form of radioactive material is utilized to eliminate various types of micro-organisms or other undesirable elements which are carried by the liquid waste material. The apparatus includes a structure comprising a plurality of parallel baffles arranged about a substantially centrally located core mounted within the casing and structurally designed to support a plurality of radioactive material elements serving as the radiation source. The core also includes a plurality of parallel baffles which communicate with the baffles of the casing to define a somewhat serpentine flowpath along which the liquid travels as it passes through the irradiator.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
255 words
An irradiator of the type utilizing radioactive material as a source of radiation for treating liquids, said irradiator comprising: a. a casing including flow directing means to at least partially define a flowpath of said liquid as it passes through said irradiator; b. core means mounted within said casing in communication with said flow directing means such that said flowpath of said liquid as it travels through said irradiator is partially defined by said core means; c. said flow directing means of said casing having a plurality of baffles arranged in intercommunicating relation so as to at least partially determine a flowpath both to and from said core, said casing baffles being arranged in adjacent parallel relation to one another, each of said casing baffles intercommunicating with at least one other adjacent casing baffle, whereby said liquid is successively directed through predetermined casing baffles as it travels through said irradiator, and said core means having a plurality of baffles arranged in intercommunicating relation to one another so as to at least partially define the portion of said flowpath within said core, certain of said core baffles being positioned in intercommunicating relation with predetermined baffles of said casing, whereby a continuous flowpath from said liquid is established as it passes through said irradiator; d. means attached to said core to support a plurality of radiation sources in exposed irradiating relation to said flowpath; and e. inlet and outlet means cooperating with said casing to permit ingress and egress of liquid as it flows through said irradiator.
Claim 2
Dependent Claim
255 words
An irradiator of the type utilizing radioactive material as a source of radiation for treating liquids, said irradiator comprising: a. a casing including flow directing means to at least partially define a flowpath of said liquid as it passes through said irradiator; b. core means mounted within said casing in communication with said flow directing means such that said flowpath of said liquid as it travels through said irradiator is partially defined by said core means; c. said flow directing means of said casing having a plurality of baffles arranged in intercommunicating relation so as to at least partially determine a flowpath both to and from said core, said casing baffles being arranged in adjacent parallel relation to one another, each of said casing baffles intercommunicating with at least one other adjacent casing baffle, whereby said liquid is successively directed through predetermined casing baffles as it travels through said irradiator, and said core means having a plurality of baffles arranged in intercommunicating relation to one another so as to at least partially define the portion of said flowpath within said core, certain of said core baffles being positioned in intercommunicating relation with predetermined baffles of said casing, whereby a continuous flowpath from said liquid is established as it passes through said irradiator; d. means attached to said core to support a plurality of radiation sources in exposed irradiating relation to said flowpath; and e. inlet and outlet means cooperating with said casing to permit ingress and egress of liquid as it flows through said irradiator.
Claim 3
Dependent Claim
64 words
An irradiator as in claim 1 wherein adjacent communicating casing baffles are arranged to inter-communicate with one another such that said liquid flows parallel to the longitudinal axis of said casing baffles but in an opposite direction in each successively communicating casing baffle partially defining said flowpath; whereby said flowpath of said liquid has a generally serpentine configuration as it travels through said irradiator.
Claim 4
Dependent Claim
70 words
An irradiator as in claim 1 wherein adjacent communicating core baffles are arranged to inter-communicate with one another such that said liquid flows parallel to the longitudinal axes of said core baffles but in an opposite direction in each successively communicating core baffle partially defining said flowpath within said core; whereby said flowpath of said liquid within said core has a generally serpentine configuration as it travels through said irradiator.
Claim 5
Dependent Claim
51 words
An irradiator as in claim 1 wherein said radiation source supporting means comprises: a plurality of sleeves adapted and arranged to support a separate source of radiation, said sleeves each being mounted within one of said core baffles so as to be directly in line with said flowpath within said core.
Claim 6
Dependent Claim
33 words
An irradiator as in claim 4 wherein said sleeves have an elongated configuration designed to support a pencil of radioactive material, said sleeves each being mounted parallel to one of said core baffles.
Claim 7
Dependent Claim
34 words
An irradiator as in claim 4 wherein each if said core baffles has a plurality of sleeves mounted therein such than an individual source of radiation is removably supported within each of said sleeves.
Claim 8
Dependent Claim
50 words
An irradiator as in claim 1 further comprising a cover shield secured to said casing, said inlet and outlet means arranged on said shield in angular relation to both said shield and said casing; whereby harmful radiation is prohibited from escaping from said casing through said inlet and outlet means.
Claim 9
Dependent Claim
188 words
An irradiator of the type utilizing radioactive material as a source of radiation for treating liquids, said irradiator comprising: a. a casing having a plurality of baffles arranged in adjacent inter-communicating relation to one another so as to define a predetermined flowpath throughout said casing, pre-determined casing baffles inter-communicating with adjacent casing baffles at points axially spaced from one another in opposite directions; b. a core mounted within said casing in communication with said casing baffles, said core including a plurality of baffles arranged in adjacent to one another and to predetermined casing baffles so as to partially define said flowpath, said core baffles inter-communicating with adjacent baffles, along said flowpath, at points axially spaced from one another in opposite directions; whereby said flowpath has a generally serpentine configuration through said irradiator; c. means attached to said core to individually support a plurality of radiation sources in plurality of core baffles so as to arrange said radiation sources in exposed irradiating position within said flowpath; and d. inlet and outlet means cooperating with said casing to permit ingress and egress of liquid as it flows through said irradiator.
Claim 10
Dependent Claim
188 words
An irradiator of the type utilizing radioactive material as a source of radiation for treating liquids, said irradiator comprising: a. a casing having a plurality of baffles arranged in adjacent inter-communicating relation to one another so as to define a predetermined flowpath throughout said casing, pre-determined casing baffles inter-communicating with adjacent casing baffles at points axially spaced from one another in opposite directions; b. a core mounted within said casing in communication with said casing baffles, said core including a plurality of baffles arranged in adjacent to one another and to predetermined casing baffles so as to partially define said flowpath, said core baffles inter-communicating with adjacent baffles, along said flowpath, at points axially spaced from one another in opposite directions; whereby said flowpath has a generally serpentine configuration through said irradiator; c. means attached to said core to individually support a plurality of radiation sources in plurality of core baffles so as to arrange said radiation sources in exposed irradiating position within said flowpath; and d. inlet and outlet means cooperating with said casing to permit ingress and egress of liquid as it flows through said irradiator.
