    Application of Simon L. RUSKIN.
    Patent Appeal No. 7413.
    United States Court of Customs and Patent Appeals.
    July 1, 1965.
    Ralph L. Chappell, John F. Smith, New York City, for, appellant.
    Clarence W. Moore, Washington, D. C. (Jere W. Sears, Washington, D. C., of counsel), for the Commissioner of Patents.
    Before WORLEY, Chief Judge, and RICH, MARTIN, SMITH, and ALMOND, Judges.
   MARTIN, Judge.

This is an appeal from the Board of Appeals which affirmed the examiner’s rejection of apparatus claims 8 and 9 in appellant’s application, serial No. 738,-573, filed May 28, 1958 for “Process for the Conversion of Hydrogen,” as covering but obvious variations of two references.

Hydrogen is a component of certain missile propellants and is most effective in the unstable “ortho” state. However, the unstable ortho-hydrogen presents danger of premature ignition. The more stable liquid para-hydrogen, while clearly the better type for storage, has a lower evaporation rate and activity, and thus is less desirable as a fuel. Appellant’s invention is directed to an apparatus inserted into the fuel line between storage tanks of para-hydrogen and a combustion chamber for the conversion of the stable para-hydrogen into the more useful fuel, ortho-hydrogen, just prior to its introduction into the combustion chamber.

As seen in appellant’s Fig. 2 reproduced below:

the apparatus comprises a series of magnets, specifically alnico magnets, which are centrally disposed in the fuel line, preferably thus maintained within a plastic tube and centrally positioned by radial spacers of a non-magnetie material. The magnets in the plastic tube are arranged so that adjacent poles of different magnets have the same polarity, thus: N-S S-N N-S, etc. The liquid para-hydrogen, along with some hydrogen gas, flows from the storage tank through the annular space between the central magnets and the fuel line. The para-hydrogen, as it flows, cuts the generally radial and perpendicular magnetic fields of the magnets and is converted to the ortho state. There is no dispute that magnetic fields will effect the conversion from para- to ortho-hydrogen, both appellant and the Patent Office acknowledging that the phenomenon was known. The Patent

Office is apparently satisfied that the appellant’s device is operable.

Appellant’s claim 8 reads:
8. In an apparatus for supplying hydrogen from a liquefied reservoir source wherein it resides in a para state to an expansion and combustion chamber wherein it exists in an enriched ortho state concentration comprising a para to ortho converting supply line interconnecting said reservoir and said chamber, said supply line being constricted so as to cause a relatively high liquid velocity flow therethrough, and having an internally mounted series of permanent magnets so as to define an annular fluid passageway with said supply line inner wall, said permanent magnets being serially arranged in continuous like-pole to like-pole opposition.

The references relied on for the rejection are:

Winslow et al. 2,583,522 Jan. 22, 1952

Vermeiren 2,652,925 Sept 22, 1953

Winslow et al. (Winslow) is directed to an apparatus for removing particles of foreign matter from fluids, more particularly, metal particles from oil. The apparatus consists of an elongated cylinder with an axially disposed inlet at one end through which particle-laden oil flows. The oil contacts horseshoe-shaped magnets which are positioned on a rod passing through the open central area of each. The rod is axially disposed in the cylinder, and each magnet thereon is separated from the adjacent magnet by a non-magnetic spacer. The effective magnetic field exists between the magnet’s gap, and each gap- is turned slightly with respect to the gap of the adjacent magnet so that the resultant fields form a helix within the cylinder. Spaced from and disposed around the axial magnet-holding rod is a fine cylindrical screen. After contacting the magnets, which retain fine metal particles, the oil flows through the screen and out the top of the cylinder through a radially disposed single outlet.

The Vermeiren apparatus is directed to a device for the “treatment of liquids which give rise to the formation of calcareous incrustations,” specifically, the removal of minerals such as calcium from water. Reference to the Fig. 3 of Vermeiren will assist in the description:

The Vermeiren device consists of a water pipe 1, around which are disposed a series of annular permanent magnets 4. The adjacent poles of different magnets have the same polarity as shown. There is a central member 2, which constricts the water flow to an annular path. The central member 2 is composed of a material “having high magnetic permeability.” The arcuate dashed lines in Fig. 3 represent magnetic field lines passing from the poles of the annular magnets into the central member. Vermeiren states: “the jets of liquid must cut normally the lines of force of the magnetic fields.”

The board affirmed the examiner’s rejection of claims 8 and 9, for the reason that:

* * * In our opinion it would be quite obvious to one having no more than ordinary skill in this art to substitute for the exterior magnets of Vermeiren interior magnets as indicated in Winslow et al. Appellant’s arguments directed to the intended use of the apparatus and to labelling of apparatus parts with relation to the intended function thereof are not significant as to the apparatus claims before us.

The board then made an additional rejection:

In addition to the Examiner’s position we consider the Vermeiren apparatus substantially to meet the terms of appellant’s claims since the interiorly disposed material of high magnetic permeability (part 2) will become magnetic by induced magnetism and will be the functional equivalent of appellant’s permanent magnets. * * * we are unable to discern a difference between appellant’s claimed apparatus and that of Vermeiren.

Appellant has fully discussed both grounds of rejection in submitting on brief to this court.

On the merits of the case, however, we do not agree with the board. It appears correct that Vermeiren’s magnet in combination with the magnetically permeable central part may be considered functionally equivalent to appellant’s magnets. However, the functional equivalent is not enough to be a full anticipation of the specific device claimed by appellant. It is important to note that appellant’s claims are drawn to specific structure, rather than being in a broad “means for” form. It is such latter type of claim which may be anticipated by an apparatus whose structure, though different, achieves the same result. Clearly the string of separate central magnets claimed is not structurally met by the annular magnet plus central permeable part of Vermeiren. Nor can Vermeiren be taken to anticipate the relationship of appellant’s “converting supply line” structure connected between the “reservoir source” and “combustion chamber,” as claimed. Thus the rejection on Vermeiren under 35 U.S.C. § 102 cannot be sustained.

Nor do we think the combination of Winslow with Vermeiren shows that appellant’s device is obvious to one of ordinary skill “in the art to which said subject matter pertains.” While Winslow and Vermeiren are both in what may broadly be called the fluid purification art, we find no suggestion in either that the structure, function or utility of Win-slow can be imported to that of Vermeiren in part or in whole. To make the substitution of the separate central magnets of Winslow for the permeable central part and the annular magnets of Vermeiren would result in the provision of helically oriented horseshoe magnets, which is not the magnet structure of appellant.

The Patent Office argues that it relies on Winslow only for the teaching of centrally disposing magnets, rather than as showing the particular structure. While Winslow does show the concept of a central magnet part within the context of his apparatus for its particular use, the reference cannot fairly be taken to teach the general modification of a device such as Vermeiren’s water softener to produce the device of appellant. Winslow lacks an indication that his central magnets are any more than a specific structure devised to solve a specific problem, which is not that of Vermeiren.

Even were we to grant that Winslow teaches the use of a central magnet in place of Vermeiren’s combination of annular magnet plus central part, we think that the two patents, as a combination of a teaching from an oil purifier modifying a water treating device, to be unrelated to the application to which appellant’s device is put. We find no suggestion in the two references that it would be obvious to provide a device such as that claimed to convert para-hydrogen to the ortho form, even considering that the principle of hydrogen conversion by magnetism was already known. We think the board failed to consider the art and problems therein as being completely foreign to the concepts of the references, and further erred in finding merely functionally equivalent structure to anticipate the specific structure claimed.

Accordingly the decision of the board is reversed.

Reversed.

      * * * H2, consists of two types: ortho- and para- which differ slightly in physical properties; as, specific heat; vapor pressure. They are explained by the different spins of the two nuclei, which may be:
