Are there any?
my dictionary does not know the word "transpile"
what do you what?
evaluating ruby code inside an C Program or porting c-structs or c++
classes into ruby objects?
both is possible

translating an ruby program into an c program is not as simple possible
because of ducktyping and dynamic stuff like including and extending
objects ans classes
c or c++ chould not handle that as simple

Translators I know of are ruby2c and ruby2cext:
https://rubyforge.org/projects/ruby2c/
https://rubyforge.org/projects/ruby2cext/
Never tried the later.

I wondered as well. To me it sounds like "read a Ruby program and
output a pile of C code" where "pile" doesn't necessarily need to be a
complete program. 
evaluating ruby code inside an C Program or porting c-structs or c++
classes into ruby objects?
Or translate a Ruby program into a C program?
Kind regards

Performance gains would probably be marginal - unless all the dynamic
features were omitted.

Nobody talked about "simple" though.
Btw, this is exactly what was asked:

Hmm
It would seem to assume that the source is a subset to the target
language. Which would explain Pascal to C but the unlikeliness of C to
Pascal.
So perhaps Ruby to Scheme which could then be compiled with the Gambit
Scheme compiler.
Not sure what the upside would be other than the bragging rights

For type-inferred code we saw ~12x improvements. For straight translations w/ fully dynamic ruby we saw marginal performance losses because we couldn't cheat the way the interpreter does (eg regexp match nodes dispatched directly where we had to use rb_funcall or we couldn't take advantage of COW string hacks).
I demonstrated this in my rubyconf 2005 talk. I don't think any video of it exists.

Translating was a lot less tough than I thought it would be (compared to, say, the parsing of ruby).

Well, both Pascal and C are Turing complete - so conversion in either
direction is possible. Of course, if you look to the small details
needed for driver implementations such as direct memory access a
standard Pascal will have a hard time doing all C's tricks. But this
is basically just a question of the standard library provided.
