  • Patent number: 11807560
    Abstract: A water treatment system includes an ozone generator combined with an electrolytic chlorine generator in a compact, efficient and serviceable assembly. The system may include a modular and replaceable ozone generator, which allows a damaged or non-functional ozone generator to be quickly and efficiently replaced. In order to protect the ozone generator from damage, a fail-safe drain valve assembly may also be provided which will expel backflowing pool water before it is allowed to backflow into the ozone generator. The water treatment system may further include an insulated electrolytic chlorine generator that mitigates or eliminates current leakage for efficient operation.

  • Patent number: 11078476
    Abstract: This invention provides a technology for isolating nucleic acids from wax-embedded samples that is superior to the current state of the art. Standard protocols with this objective typically comprise dissolving the wax-embedded sample in an organic solvent, extracting nucleic acids from the organic solvent into an aqueous buffer, and isolating the nucleic acids from the aqueous buffer. The technology described here includes using hexadecane as the solvent to dissolve the sample, precipitating and washing the extracted nucleic acids, and dissolving the nucleic acids in a lysis buffer that includes NP40 and SDS. By implementing the reagents and techniques described in this disclosure, the user can obtain a product that has better yield, less degradation, and contains more unique mRNA transcripts for subsequent sequencing and analysis.
