Abstract: This invention provides a duct cover system for ducts installed in exposed locations. For use primarily with ducts having generally rectangular cross sections, the duct cover system provides a roof over the duct that may be integral with the duct or retrofitted to the duct. The roof includes at least one cover panel extending along the duct length. The cover panel is inclined laterally relative to the duct bottom wall thereby to shed water and prevent snow accumulation.

Abstract: There is disclosed herein a machine for performing nucleic acid amplification under computer control. The machine utilizes any one of a number of heating and cooling systems under control of a host computer which directs the heating and cooling systems to heat and cool a reaction-chamber-containing heat exchanger at appropriate times in the process. The reaction chambers are pre-loaded with the nucleic acid(s) to be amplified, a thermostable enzyme to catalyze polymerization, specific oligonucleotide primers, and four different nucleotide triphosphates. Also disclosed is the process for the amplification chain reaction implemented by the machine, which utilizes a thermostable enzyme.
