Appeal No. 2005-0187 Appeal No. 09/758,513 The scanning head 10 shown in FIG. 1 exhibits a cylindrical housing 16, which is sealed against chips, coolant and lubricant and similar disturbing influences. The cable 14 for connecting to the controller 12 is attached to the scanning head 10 by means of a screwable connector 18. In the housing 16 there is an electric motor 20, which is designed as a d.c. motor. The electric motor 20 is fed so as to reverse the polarity by means of a motor driver 22, disposed in the controller 12, via the cable 14. The electric motor 20 drives by way of a precision tooth gearing 24 a shaft 26, which is run coaxially on the face side out of the housing 16. A double lip seal 28 seals the passage of the shaft 26 through the face- sided cover of the housing 16 against chips and coolant. O-ring seals 30 seal the respective face- sided cover[s] of the cylindrical housing 16. A pin holder 32, into which a feeler pin 34 can be clamped, is clamped via a setscrew 36 on the stump of the shaft 26 that projects beyond the housing 16. The feeler pin 34 that is clamped into the pin holder 32 protrudes radially from the shaft 26 [column 2, line 46, through column 3, line 5]. Anticipation is established only when a single prior art reference discloses, expressly or under principles of inherency, each and every element of a claimed invention. RCA Corp. v. Applied Digital Data Sys., Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed. Cir. 1984). In other words, there must be no difference between the claimed invention and the reference disclosure, as viewed by a person of ordinary skill in the field of the invention.
