Google indicated that when it downloaded that page, it was given a PDF
document.  It then has a few snippets of the text of that PDF as part
of the search results.

PDFs are not cached at google like web pages (or, at least, they
aren't provided inside their cache for you to grab) otherwise one
could just do a google search for
"cache:http://linkinghub.elsevier.com/retrieve/pii/S0041624X05000582"
and get the PDF that google saw when it last crawled it.

If one can look exactly like the google crawler, then one will get
that PDF just as google saw it (which may not be the full pdf,
either).  But that may be non-trivial depending on how cloaked the pdf
is.
