Abstract
Abstract A separating nozzle element composed of a separating body and end plates enclosing the body, for separating components of gaseous or vaporous mixtures, the separating body being provided with separating structures which delimit separating chambers and gas conduits and the end plates being provided with channels for supplying gas to, and removing gas streams from, the separating chambers and conduits, in which the separating body is produced in successive contiguous layers by carrying out the following sequence of steps a plurality of times until a given separating body thickness is achieved: providing a mold layer; irradiating selected portions of the layer with radiation in a spatial pattern corresponding to the separating structures to render only selected regions of the layer which correspond to the separating structures removable in a predetermined manner; removing the selected regions; and filling the spaces thus created in the layer with a material which is compatible with the gaseous or vaporous mixture whose components are to be separated, in order to form a laminar portion of the separating structures, and after the desired thickness is achieved, removing the remaining material of the mold layers.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
235 words
A method for producing a separating nozzle element composed of a separating body and end plates enclosing the body, for separating components of gaseous or vaporous mixtures, the separating body being provided with separating structures which delimit separating chambers and gas conduits and the end plates being provided with channels for supplying gas to, and removing gas streams from, the separating chambers and conduits, comprising: (a) producing the separating body in successive contiguous layers by carrying out the following sequence of steps a plurality of times until a given separating body thickness is achieved: (i) providing a mold layer of a material whose ability to be removed by a predetermined procedure is influenced by that application thereto of radiation of a given type; (ii) irradiating selected portions of the layer with an effective amount of the given type of radiation in a spatial pattern corresponding to the separating structures to render only selected regions of the layer which correspond to the separating structures removable in the predetermined manner; (iii) removing the selected regions by performing the predetermined procedure on the irradiated layer; and (iv) filling the spaces created in the layer by said step of removing with a material which is compatible with the gaseous or vaporous mixture whose components are to be separated, in order to form a laminar portion of the separating structures; and (b) removing the remaining material of the mold layers.
Claim 2
Independent Claim
235 words
A method for producing a separating nozzle element composed of a separating body and end plates enclosing the body, for separating components of gaseous or vaporous mixtures, the separating body being provided with separating structures which delimit separating chambers and gas conduits and the end plates being provided with channels for supplying gas to, and removing gas streams from, the separating chambers and conduits, comprising: (a) producing the separating body in successive contiguous layers by carrying out the following sequence of steps a plurality of times until a given separating body thickness is achieved: (i) providing a mold layer of a material whose ability to be removed by a predetermined procedure is influenced by that application thereto of radiation of a given type; (ii) irradiating selected portions of the layer with an effective amount of the given type of radiation in a spatial pattern corresponding to the separating structures to render only selected regions of the layer which correspond to the separating structures removable in the predetermined manner; (iii) removing the selected regions by performing the predetermined procedure on the irradiated layer; and (iv) filling the spaces created in the layer by said step of removing with a material which is compatible with the gaseous or vaporous mixture whose components are to be separated, in order to form a laminar portion of the separating structures; and (b) removing the remaining material of the mold layers.
Claim 3
Dependent Claim
34 words
A method as defined in claim 1 further comprising rendering each mold layer insensitive to the given type of radiation after each said step of filling and before the next succeeding step of providing.
Claim 4
Dependent Claim
47 words
A method as defined in claim 1 or 2 wherein the material of the mold layer is an electrical nonconductor, the material employed in each said step of filling is an electrical conductor, and each said step of filling is carried out by an electrochemical deposition operation.
Claim 5
Dependent Claim
38 words
A method as defined in claim 1 or 2 comprising the preliminary step of forming one end plate by providing a base plate and forming channels therein, and wherein the separating body is produced on said end plate.
Claim 6
Dependent Claim

Claim 11
Dependent Claim
61 words
A method as defined in claim 1 or 2 further comprising forming one of the end plates by disposing masses of mold material to conform to the channels of the end plate, and disposing material compatible with, and impervious to, the gaseous or vaporous mixtures in a layer around and between the masses of mold material to constitute the end plate.
Claim 12
Dependent Claim
49 words
A method as defined in claim 10 wherein the material of the mold layer is an electrical nonconductor, the materials employed in each said step of filling and for the end plate are electrical conductors, and each said step of filling is carried out by an electrochemical deposition operation.
Claim 13
Dependent Claim
72 words
A separating nozzle element produced according to the method defined in claim 1 and presenting a plurality of adjacent separating nozzle systems each having at least one separating chamber communicating with an associated inlet conduit and outlet conduit, wherein each said inlet conduit communicates with said chambers of an associated pair of adjacent nozzle systems and each said outlet conduit communicates with said chambers of an associated pair of adjacent nozzle systems.
Claim 14
Dependent Claim
126 words
A separating nozzle element produced according to the method defined in claim 1 wherein said separating body is composed of a plurality of elongate arm members connected end to end and extending along a serpentine path sandwiched between said end plates such that a respective gas collection chamber is formed between each pair of arms and associated portions of said end plates, each said arm presents a plurality of adjacent separating nozzle systems each having at least two outlet conduits for conducting respective components separated from the mixture, and said outlet conduits are arranged relative to said collection chambers such that the collection chambers located at respectively opposite sides of each said arm receive respectively different components from said nozzle structures presented by that said arm.
