Calorimeter

A calorimeter vessel for receiving a sample holding calorimeter bomb comprising:

• base means defining a support for a calorimeter bomb including means for supplying water therethrough;
• a container having sidewalls and being substantially enclosed at one end and open at an opposite end, said open end of said container sealably engagable with said base means with said sidewalls circumscribing said water supply means wherein said container is generally vertically oriented and defines a concavely opening chamber extending downwardly;
• means for moving said container with respect to said base means for opening and closing said vessel defined thereby;
• and
• water level detection means associated with said container at first and second levels, and control means coupled to said water supply means and to said detection means for supplying water initially to said first level at a first rate and subsequently to said second level at a second flow rate, wherein said water supply means includes aperture means extending through said base for providing a first flow path of water and conduit means coupled to said container at an end remote from said open end to provide a second lower flow rate of water to said vessel.

A calorimeter vessel for receiving a sample holding calorimeter bomb comprising:

• base means defining a support for a calorimeter bomb;
• a downwardly opening concave container sealably engagable with said base means;
• cylinder means extending between said base and said container for moving said container with respect to said base means for selectively opening and closing said vessel defined thereby and sealing said vessel when in a closed position;
• and
• means for supplying water to said vessel to fill said vessel to a first level at a first flow rate and subsequently to a second level at a second rate slower than said first rate.

• water level detection means associated with said container at first and second levels, and control means coupled to said water supplying means and to said detection means for supplying water initially to said first level at said first rate and subsequently to said second level at said second flow rate, wherein said water supply means includes aperture means extending through said base for providing a first flow path of water;
• and
• conduit means coupled to said container at an end remote from said open end to provide a second lower flow rate of water to said vessel.

A calorimeter system comprising a plurality of calorimeter vessels each including base means for supporting a calorimeter bomb thereon and a container sealably mounted to the base and movable between open and closed positions for loading the bomb within the vessel so formed and for conducting an analysis respectively;

• a common supply of water and conduit means coupling said supply to each of said vessels, said conduit means including control valve means;
• control means for actuating said control valve means for selectively filling and emptying each of said vessels with water;
• water level detection means associated with each of said containers at first and second levels, wherein said control means is coupled to said detection means for actuating said control valves for supplying water initially to said first level at a first rate and subsequently to said second level at a second flow rate;
• and
• means for circulating water through each of said vessels comprising pump means coupled to remove water from one end of said vessel, and conduit means extending from said pump to an opposite end of said vessel for circulating water through each of said vessels during an analysis.
