Pressure cycling reactor
First Claim
Patent Images
1. A pressure cycling reactor for conducting a controlled pressure sensitive reaction comprising,a reaction vessel for containing a sample, a vessel pressurizer connected to the reaction vessel, and a controller connected to the vessel pressurizer for signalling the pressurizer to maintain reaction inactivating pressure P1 in the reaction vessel and signalling the pressurizer to change pressure in the reaction vessel to a reaction activating pressure P2 for a pulsed period t1 and then recycling to a reaction inactivating pressure P3 in the reaction vessel.

26. A reactor for intermittently inhibiting activity of a sample by controlling temperature and pressure conditions of the sample, comprising:
-
a reactor body defining a chamber for receiving the sample, a pressurizer in communication with said chamber mounted for movement between a first position for applying a first predetermined pressure P1 to said chamber, said first predetermined pressure P1 being selected to inhibit activity of the sample, and a second position for changing said chamber pressure to a second predetermined pressure P2 selected to allow activity of the sample, a switch having a first state and a second state to move said pressurizer between said first position and said second position, a controller for changing said switch between said first and second states, means for adjusting temperature in said chamber, and a port in communication with said chamber for removal of the sample from said chamber.
