  • Patent number: 7205459
    Abstract: According to the invention, there is provided an inbred corn plant designated LIZL5. This invention thus relates to the plants, seeds and tissue cultures of the inbred corn plant LIZL5, and to methods for producing a corn plant produced by crossing the inbred corn plant LIZL5 with itself or with another corn plant, such as another inbred. This invention further relates to corn seeds and plants produced by crossing the inbred plant LIZL5 with another corn plant, such as another inbred, and to crosses with related species. This invention further relates to the inbred and hybrid genetic complements of the inbred corn plant LIZL5, and also to the SSR and genetic isozyme typing profiles of inbred corn plant LIZL5. This invention further relates to methods of transforming the inbred LIZL5 and cells thereof, transformed plants produced by these methods, progeny transgenic plants, and seed derived therefrom.

  • Patent number: 3986386
    Abstract: A method and apparatus for measuring particulates contained in the exhaust gases from internal combustion engines which dilutes the exhaust gases with prefiltered and precooled air to produce a constant volume mixture which may be sampled for exhaust gas emissions as well as for particulates. After mixing of the exhaust gases and the pretreated air, sampling of the mixture by isokinetic probes produces a uniform sample of particulate matter which is collected on temperature controlled filters for analysis.
