  • Patent number: 6543932
    Abstract: An improved and accurate enthalpy tunnel is presented, designed to condition and control airflow patterns within the main tunnel and air sampling subsystem so as to present a homogenous volume immediately upon introduction into the enthalpy tunnel. The air volume velocity is slowed and the air volume is completely mixed in a settling chamber which also serves to maintain the static discharge pressure on the unit under test. The rectangular design in use in the industry is replaced with circular geometry, using a cylindrical tunnel shape as opposed to a rectangular shape. The circular geometry creates a flat, uniform velocity profile. This tunnel improves the design of current art enthalpy tunnels by using a single nozzle instead of a bank of nozzles, presenting to the sampling mechanism a smooth, stable and uniform flow profile. The sampling method used in the prior art is replaced with a sampling tunnel that also conditions its air flow profile, leading to consistent sampling.

  • Patent number: 6521746
    Abstract: New immunological carrier systems, DNA encoding the same, and the use of these systems, are disclosed. The carrier systems include chimeric proteins which include a leukotoxin polypeptide fused to one or more selected GnRH multimers which comprise at least one repeating GnRH decapeptide sequence, or at least one repeating unit of a sequence corresponding to at least one epitope of a selected GnRH molecule. Under the invention, the selected GnRH sequences may all be the same, or may correspond to different derivatives, analogues, variants or epitopes of GnRH so long as the GnRH sequences are capable of eliciting an immune response. The leukotoxin functions to increase the immunogenicity of the GnRH multimers fused thereto.
