EBMisor Response to amendment filed Feb. 20, 1912. Cancel Figs. 1 and 2 and amend the specifi cation accordingly. Claim 7 is objected to as being substantially identical with claim 8 and also on account of the expression"spaced plane surfaces". A "surface" cannot be an element of a claim; the part having the surface should be directly included. There will probably be an interference involving all the remaining claims.
