Abstract
Abstract A method of producing separating nozzles with slot-shaped nozzle-channels of a very high degree of accuracy for separating gaseous or vaporous substances into particles of different molecular weights, this method consisting of first producing a thin molding bar which consists of a material which may be easily melted or chemically dissolved and is made of a size and shape exactly corresponding to those of the inner surfaces of two walls of the nozzle channel which consist of strips of a very thin sheet metal which are applied upon and thus molded to the shape of this bar. Small partitions of sheet metal are also inserted into the molding bar which, when the nozzle walls are completed and the material of the molding bar is completely removed, remain between and thereby reinforce the nozzle walls.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
24 words
A method as defined in claim 1, in which said filling material is removed by thermal action from said nozzle walls and said partitions.
Claim 2
Dependent Claim
24 words
A method as defined in claim 1, in which said filling material is removed by chemical action from said nozzle walls and said partitions.
Claim 3
Dependent Claim
22 words
A method as defined in claim 1, in which said partitions are produced before said strips are applied upon said molding bar.
Claim 4
Dependent Claim
56 words
A method as defined in claim 1, in which said partitions are secured to a supporting element so as to project therefrom and to be disposed in a row behind each other, whereupon the spaces between the adjacent partitions are filled out with said filling material so as to form said molding bar containing said partitions.
Claim 5
Dependent Claim
57 words
A method as defined in claim 5, in which said partitions are produced by being partly punched out of and erected from said supporting element so that each partition remains connected to said supporting element at one side extending transverse to said row and is bent about said side so as to project from said supporting element.
Claim 6
Dependent Claim
46 words
A method as defined in claim 6, in which when said spaces between said adjacent partitions are filled out with said filling material, the apertures formed in said supporting element when said partitions are partly punched out therefrom are likewise filled out with said filling material.
Claim 7
Dependent Claim
22 words
A method as defined in claim 1, in which said strips are applied upon said molding bar so as to adhere thereto.
Claim 8
Dependent Claim
21 words
A method as defined in claim 1, in which said strips are produced by a galvanic process on said molding bar.
Claim 9
Dependent Claim
39 words
A method as defined in claim 1, further comprising the step subsequent to the application of the strips upon said molding bar of finishing one of said strips so that its end portion terminates into a thin separating edge.
Claim 10
Dependent Claim
53 words
A method as defined in claim 1, in which said strips forming the walls of said nozzle channel including the very thin edges of the ends of said walls are applied upon said molding bar in the form of a rolled sheet metal after it has been rolled substantially to its final shape.
Claim 11
Dependent Claim
22 words
A method as defined in claim 1, in which said filling material forms the support of said partitions in said molding bar.
Claim 12
Dependent Claim
28 words
A method as defined in claim 12, in which said partitions are inserted into said filling material and are firmly connected to said walls of said nozzle channel.
Claim 13
Dependent Claim
17 words
A method as defined in claim 1, in which said partitions are embedded in said filling material.
Claim 14
Dependent Claim
29 words
A method as defined in claim 1, in which a continuous bar of said filling material is made and then provided with slots into which said partitions are inserted.
Claim 15
Dependent Claim
21 words
A method as defined in claim 1, in which said filling material consists of a nonmetallic material such as casting resins.
Claim 16
Dependent Claim
17 words
A method as defined in claim 1, in which said filling material consists of a casting metal.
Claim 17
Dependent Claim
21 words
A method as defined in claim 1, in which said walls of said nozzle channel consist of a chemically resistant metal.
Claim 18
Dependent Claim
24 words
A method as defined in claim 1, in which said walls of said nozzle channel consist of a metal having a high melting point.
Claim 19
Dependent Claim
27 words
A method as defined in claim 1, in which said walls of said nozzle channel consist of a metal containing nickel at least as an alloy component.
Claim 20
Dependent Claim
29 words
A method as defined In claim 1, in which said walls of said nozzle channel consist of a metal containing a precious metal at least as an alloy component.
Claim 21
Dependent Claim
42 words
A method as defined in claim 4, in which said partitions and said filling material when combined so as to form said molding bar are machined together to the size and shape corresponding to the inner cross section of said nozzle channel.
Claim 22
Dependent Claim
35 words
A method as defined in claim 9, in which when producing said strips forming the walls of said nozzle channel by a galvanic process the very thin parts of said walls are attained by masking.
Claim 23
Dependent Claim
29 words
A method as defined in claim 13, in which said partitions are inserted into said slots in said filling material before the strips are applied upon said molding bar.
Claim 24
Dependent Claim
22 words
A method as defined in claim 12, in which said partitions are inserted into said filling material so as to adhere thereto.
Claim 25
Dependent Claim
28 words
A method as defined in claim 15, in which said partitions are formed in said slots in said filling material together with the formation of said nozzle walls.
Claim 26
Dependent Claim
22 words
A method as defined in claim 26, in which said partitions and said nozzle walls are produced together by a galvanic process.
Claim 27
Dependent Claim
17 words
A method as defined in claim 12, in which said filling material consists of a casting metal.
Claim 28
Dependent Claim
26 words
A method as defined in claim 12, in which said filling material consists of a metallic material containing a light metal at least as a component.
Claim 29
Dependent Claim
27 words
A method as defined in claim 9, in which said walls of said nozzle channel consist of a metal containing copper at least as an alloy component.
