I. CLAIMS IN DIFFERENT CATEGORIES
Example 1
Claim 1: A method of manufacturing chemical substance X.
Claim 2: Substance X.
Claim 3: The use of substance X as an insecticide.
Unity exists between claims 1, 2 and 3. The special technical feature common to all the claims is substance X.
Example 2
Claim 1: A process of manufacture comprising steps A and B.
Claim 2: Apparatus specifically designed for carrying out step A.
Claim 3: Apparatus specifically designed for carrying out step B.
Unity exists between claims 1 and 2 or between claims 1 and 3. There is no unity between claims 2 and 3 since there exists no common special technical feature between the two claims.
Example 3
Claim 1: A process for painting an article in which the paint contains a new rust inhibiting substance X including the steps of atomizing the paint using compressed air, electrostatically charging the atomized paint using a novel electrode arrangement A and directing the paint to the article.
Claim 2: A paint containing substance X.
Claim 3: An apparatus including electrode arrangement A.
Unity exists between claims 1 and 2 where the common special technical feature is the paint containing substance X or between claims 1 and 3 where the common special technical feature is the electrode arrangement A.
However, unity is lacking between claims 2 and 3 since there exists no common special technical feature between them.
Example 4
Claim 1: Use of a family of compounds X as insecticides.
Claim 2: Compound X1 belonging to family X.
Provided X1 has the insecticidal activity and the special technical feature in claim 1 is the insecticidal use, unity is present.
Example 5
Claim 1: A process for treating textiles comprising spraying the material with a particular coating composition under special conditions (e.g., as to temperature, irradiation).
Claim 2: A textile material coated according to the process of claim 1.
Claim 3: A spraying machine for use in the process of claim 1 and characterized by a new nozzle arrangement providing a better distribution of the composition being sprayed.
The process according to claim 1 imparts unexpected properties to the product of claim 2.
The special technical feature in claim 1 is the use of special process conditions corresponding to what is made necessary by the choice of the particular coating. Unity exists between claims 1 and 2.
The spraying machine in claim 3 does not correspond to the above identified special technical feature. Unity does not exist between claim 3 and claims 1 and 2.
Example 6
Claim 1: A fuel burner with tangential fuel inlets into a mixing chamber.
Claim 2: A process for making a fuel burner including the step of forming tangential fuel inlets into a mixing chamber.
Claim 3: A process for making a fuel burner including casting step A.
Claim 4: An apparatus for carrying out a process for making a fuel burner including feature X resulting in the formation of tangential fuel inlets.
Claim 5: An apparatus for carrying out a process for making a fuel burner including a protective housing B.
Claim 6: A process of manufacturing carbon black including the step of tangentially introducing fuel into a mixing chamber of a fuel burner.
Unity exists between claims 1, 2, 4, and 6. The special technical feature common to all the claims is the tangential fuel inlets. Claims 3 and 5 lack unity with claims 1, 2, 4, and 6 since claims 3 and 5 do not include the same or corresponding special technical feature as set forth in claims 1, 2, 4, and 6. Claims 3 and 5 would also lack unity with one another.
Example 7
Claim 1: A high corrosion resistant and high strength ferritic stainless steel strip consisting essentially of, in percent by weight: Ni=2.0-5.0; Cr=15-19; Mo=1-2; and the balance Fe having a thickness of between 0.5 and 2.0 mm and a 0.2% yield strength in excess of 50 kg/mm squared.
Claim 2: A method of producing a high corrosion resistant and high strength ferritic stainless steel strip consisting essentially of, in percent by weight: Ni=2.0-5.0; Cr=15-19; Mo=1-2; and the balance Fe, comprising the steps of: hot rolling to a thickness between 2.0 and 5.0 mm; annealing the hot rolled strip at 800-1000 degrees C under substantially no oxidizing conditions; cold rolling the strip to a thickness of between 0.5 and 2.0 mm; and final annealing the cold rolled strip at between 1120 and 1200 degrees C for a period of 2-5 minutes.
Unity exists between product claim 1 and process claim 2. The special technical feature in the product claim is the 0.2% yield strength in excess of 50 kg/mm squared. The process steps in claim 2 inherently produce a ferritic stainless steel strip with a 0.2% yield strength in excess of 50 kg/mm squared. Even if this feature is not apparent from the wording of claim 2, it is clearly disclosed in the description. Therefore said process steps are the special technical feature which correspond to the limitation in the product claim directed to the same ferritic stainless steel with the claimed strength characteristics.
