A steam and water mixing hose station is provided with control of the steam flow ahead of its mixing with cold water which control compensates for pressure drops in either the steam or water pressure to maintain the temperature of the steam/water mixture. The hose station has a temperature controll valve on the steam supply side ahead of a mixing chamber where steam and water are mixed, a sensing chamber connected to the outlet of the mixing chamber with a temperature sensing bulb therein which is connected to the valve to regulate the steam flow to the mixing chamber based on the temperature in the sensing chamber. - 7 -

Why it's free to use
- Filed April 22, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 22, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 22, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
