Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
A sample conditioner, comprising: a heat exchange chamber comprising a coolant jacket with coolant inlet and outlet means for receiving and discharging a liquid coolant and a sample inlet means; a vapor conduit located within said coolant jacket and having one terminus sealingly secured to the sample inlet means; a series of baffles affixed within the heat exchange chamber which receive and support said vapor conduit and insure thorough circulation of a coolant about said conduit; a separation chamber comprising a container means having an opening for receiving the second terminus of the vapor conduit which is sealingly affixed to the container means along the periphery of said opening, a vapor outlet means formed in said container means, a mist coalescer affixed along the periphery of the interior wall of said container means at a point between the second terminus of the vapor conduit and the vapor outlet means, a deflector plate located between the mist coalescer and the second terminus of the vapor conduit and a condensate outlet formed in said container means.
Claim 2
Dependent Claim
174 words
A sample conditioner, comprising: a heat exchange chamber comprising a coolant jacket with coolant inlet and outlet means for receiving and discharging a liquid coolant and a sample inlet means; a vapor conduit located within said coolant jacket and having one terminus sealingly secured to the sample inlet means; a series of baffles affixed within the heat exchange chamber which receive and support said vapor conduit and insure thorough circulation of a coolant about said conduit; a separation chamber comprising a container means having an opening for receiving the second terminus of the vapor conduit which is sealingly affixed to the container means along the periphery of said opening, a vapor outlet means formed in said container means, a mist coalescer affixed along the periphery of the interior wall of said container means at a point between the second terminus of the vapor conduit and the vapor outlet means, a deflector plate located between the mist coalescer and the second terminus of the vapor conduit and a condensate outlet formed in said container means.
Claim 3
Dependent Claim
46 words
The sample conditioner of claim 1, wherein: the portion of the container means having the opening for receiving the second terminus of the vapor conduit is sealingly secured to the coolant jacket to form a common wall between the heat exchange chamber and the separator chamber.
Claim 4
Dependent Claim
14 words
The sample conditioner of claim 2, further including: baffles affixed to the vapor conduit.
Claim 5
Dependent Claim
14 words
The sample conditioner of claim 3, wherein: the vapor conduit is a coiled tube.
Claim 6
Dependent Claim
31 words
The sample conditioner of claim 4, wherein: the mist coalescer is a perforated cone to which the deflector plate is afixed at the apex thereof to form a unitary separator element.
