If you look at some hydraulic schematics, you'll see a rich duality
between electric and hydraulic circuits. For example, the pressure
drop across an orifice is analogous to the voltage drop across a
resistor. Hydraulic power is pressure * flow (i.e. V * I).

Hi Bob,
Do not discuss patents here please !
This is highly contageous and attracts law suits.
Without the mentioning of patents the general idea would have come across as
well.
Kind regards,

Oh good heavens. Mentioning the existence of a patent, and
suggesting it as good reading because it contains interesting and
geeky science stuff, attracts LAWSUITS?
Regardless, I would also say do not discuss patents here, for
various (legal and otherwise) reasons.

Ok, that's fine by me, as it's your list. But could you explain
how it could be dangerous? That suggestion sounds quite ludicrous
to me.
For starters, archived proof that you knew of the existence of a
patent automatically triples any damages you may have to pay.

Tom,
I didn't find a gschem hydraulic symbol library, so I'm attempting to
build one. My first stumbling block is the use of filled and
non-filled triangles, which differentiate hydraulic pumps from
pneumatic compressors. Is it possible to draw filled triangles or
polygons with gschem?

In general, it really does present a huge legal risk, so I agree
with the policy.
