A spacer for use with a metered dose inhaler (MDI), comprising a continuous solid metal body which defines a chamber having a total volume of between 50 and 400 ml, wherein said body has a generally oblong shape which is rotationally symmetrical about a longitudinal axis and an opening at each end, one of the openings being adapted for connection to a metered dose inhaler (MDI). 17. The spacer of claim 16, wherein the body is composed of stainless steel. THE PRIOR ART The prior art references of record relied upon by the examiner in rejecting the appealed claims are: Kraemer 5,427,089 Jun. 27, 1995 (filed Sep. 8, 1993) Calvert et al. (Calvert) 5,522,383 Jun. 4, 1996 1 Applicants' amendment (Paper No. 16), filed October 8, 1998, prior to the final rejection (Paper No. 18), includes changes to claim 16, the abstract and the specification. Notwithstanding the examiner's approval of entry of this amendment (See Paper No. 18), we note that the record does not show that the amendment has been formally entered. Nevertheless, because the examiner has indicated that the correct reading of claim 16 is that which is found in the appendix to the brief, we shall treat the copy of claim 16 in the brief as being the correct one for purposes of deciding this appeal.Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
