Appeal No. 1999-1042 Page 10 Application No. 08/781,220 The appellant’s U.S. Patent No. 5,644,876, upon which the double patenting rejection is based, resulted from application Serial Number 08/297,193, filed on August 26, 1994 (hereinafter “the patent”). This application disclosed two embodiments of the appellant’s invention. The first embodiment (Figures 1-5) discloses a four-sided column and maximizes the number of gas outlets that can be installed at a specified height on the column by providing a pair of angled outlet support surfaces on each side panel which are adjacent to one another in intersecting planes. The second embodiment (Figures 6-9)2 accomplishes a similar objective by utilizing a five-sided column in which the width of each side panel is only slightly wider than that of the gas assembly mounted thereon. The appellant prosecuted to issuance only claims directed specifically to the first embodiment. The present application was filed on January 10, 1997 as a Rule 60 continuation of the first and presented, after entry of a preliminary amendment, claims directed to the second embodiment. 2While described in the specification as illustrating the five-sided embodiment of the invention, it appears to us that Figure 6 shows a four-sided column. However, a five-sided column clearly is shown in Figures 7-9.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 NextLast modified: November 3, 2007
