(concurring).
The record shows that the Board of Appeals here consisted of an examiner-in-chief and two acting examiners-in-chief. Appellants do not challenge the legality of that board. I participate in the merits of this appeal for the reasons stated in my concurring opinion in In re Mindick, 371 F.2d 892, 54 CCPA -; see also In re Wiechert, 310 F.2d 927, 54 CCPA-. In so doing, I agree with the reasoning and conclusion of the majority.
