Thermocycler and sample vessel for rapid amplification of DNA

A thermocycler apparatus and method for rapidly performing the PCR process employs at least two thermoelectric modules which are in substantial spatial opposition with an interior space present between opposing modules. One or multiple sample vessels are placed in between the modules such that the vessels are subjected to temperature cycling by the modules. The sample vessels have a minimal internal dimension that is substantially perpendicular to the modules that facilitates rapid temperature cycling. In embodiments of the invention the sample vessels may be deformable between: a) a shape having a wide mouth to facilitate filling and removing of sample fluids from the vessel, and b) a shape which is thinner for conforming to the sample cavity or interior space between the thermoelectric modules of the thermocycler for more rapid heat transfer.

Method for combustion of a fuel

InactiveUS20050282097A1Increase in flame volumeMinimize residence timeContinuous combustion chamberGas turbine plantsCombustion chamberFront velocity
In a method for the combustion of a fuel, a fuel or a premixed combustible mixture is introduced into a combustion space as a combustible fluid open jet. The velocity of the open jet is selected in such a way that it is impossible for a stable flame front to form, i.e. is in any event greater than the flame front velocity, and that, on account of a jet pump effect, flue gas is mixed into the combustible fluid jet from the combustion chamber in a jet-induced recirculation internally within the combustion chamber. The admixed flue gas dilutes and heats the combustible fluid. The heating causes the spontaneous ignition temperature to be exceeded, and a low-pollutant volumetric flame is formed in a highly dilute atmosphere.

Method and apparatus for pumping and diluting a sample

A pumping apparatus (50) which isolates a sample (52) from a pump (72), thereby circumventing the so-called “memory effect” problem. The sample is pumped into an intermediary, or buffer region (64) using a first pump (54). The sample is displaced from this buffer region by pumping a second fluid (74) into the buffer region using a second pump (72). When the sample is displaced from the buffer region it proceeds to a mixer (78) where it can be diluted before analysis. The second pump is required to operate with a high degree of accuracy so that the sample is diluted by a consistent amount. Preferably, the second pump is a highly accurate piston pump.

Sampling and counting system

A system for testing the efficiency of a test HEPA filter, the system comprises a dilution system and a sampling system. The dilution system processes samples collected upstream of the test HEPA filter. The dilution system has a test portion and a calibrated portion. The calibrated portion aids in determining the dilution ratio of the test portion thereby rendering the dilution system self-calibrating. The sampling system receives upstream samples via the dilution system, and downstream samples collected directly downstream of the test HEPA filter. The sampling system incorporates a flow rate balancing system to ensure accurate counts with respect to samples collected upstream and downstream of the test HEPA filter. The sampling system works well with particle counters fitted with relatively weak fans to draw in samples for counting; this is achieved by connecting the sampling system to both the inlet and exhaust outlet of a particle counter.
