Abstract: This invention relates to a metathesis catalyst compound comprising an asymmetrically substituted N-heterocyclic carbene (NHC) metathesis catalyst and a process to make linear alpha-olefins comprising contacting a feed material and an optional alkene (such as ethylene) with said catalyst, where the feed material is a triacylglyceride, fatty acid, fatty acid alkyl ester, and/or fatty acid ester, typically derived from biodiesel.

Abstract: The invention is a container with a sealing lid and a compression nut and is composed of compressible cylindrical walls. The container volume can be adjusted to equal the volume of content minimizing content contact with air. The container can be further pressurized for preservation of contents that need pressurization. The container walls are created in the form of helical collapsible screw thread bellows. The integration of a compression nut, a screw and a collapsible bellow arrangement enables the container to be compressed precisely, effortlessly, easily while retaining structural rigidity, stability and providing a non-slip gripping surface. By adjusting the pitch of the screw threads a variety of mechanical advantage ratios can be achieved thus the effort for compressing the container can be optimized. The compression nut is detachable and transferable from one container to another enabling it's cost to be shared between multiple containers.

Abstract: Space saver container is a concept of shrinking containers so that its volume matches the volume of the contents. Thus as the contents are progressively consumed the container can progressively reduce in volume freeing up space outside the container for example in the closet or refrigerator where it may be stored. The reduction can be tailored to the situation in which the container is normally used. Thus in the case of say milk cartons the container reduces its foot print but in the case of ice-cream container the height is reduced thus increasing stacking space. The containers available today can create shelf space only when the contents of the containers are gone and when they are ready to be removed for disposal. The concept of space saver container volume reduction is enabled by a collapsible bellow structure that is biased to attain its maximum volume. The user forces the bellow shape to contract thus shrinking the container to match the volume of the content.
