transport chamber (claims 1, 3 to 17 and 25 to 30) and for
making a chamber (claims 21, 23, 24 and 31 to 34). They are
reproduced in Appendix A of appellants' brief.1
The references applied in the final rejection are:
Cross 1,699,688 Jan. 22,
1929
Koch et al. (Koch) 4,433,951 Feb. 28,
1984
Claims 1, 3 to 17, 21 and 23 to 34 stand finally rejected
as
unpatentable over Koch in view of Cross, under 35 U.S.C.
§ 103(a).
The examiner takes the position that, as to claim 1, Koch
discloses all the claimed limitations, except "generating a
chamber housing from a rolled forging that is a solid aluminum

1In reviewing the drawings of the application, we note
the following, which should be corrected: (1) Figs. 1, 2A and
2B should be labeled "Prior Art," Manual of Patent Examining
Procedure § 608.02(g). (2) Reference numerals 500 (p. 13,
line 12), 700 (p. 15, line 24) and 706 (p. 16, line 17) are
not in the drawings. (3) In Figs. 5B and 7, ports 316 are not
properly illustrated. Since the interior of housing 302 is
cylindrical and the outside has facets 305, the walls would be
of varying thickness, but ports 316 are shown as though the
inner and outer wall surfaces are parallel. Also, the upper
two ports are not parallel to the upper surface of the
chamber.
