Abstract: A method, system and apparatus for selecting cells is disclosed. An example embodiment provides spatial information denoting the location, on a four part array of sensors, referred to as a quad array, of the center, of each particle that passes through the focused laser beam in a cell sorter. The center of a particle is commonly determined by the average fluorescence intensity within the field of view of a Side Fluorescence (SFL) collection lens. Fluorescence collected by an SFL lens from a particle having any orientation and any position in the core stream produces a spot large enough to illuminate all four segments of a quad array. By independently measuring the fluorescence intensity recorded by each of the four array segments for a particle, it is possible to calculate the x-y coordinate position across the quad array segments of the average total fluorescence emission collected from that particle.

Abstract: A container with a lid sealed thereon wholly encloses a space which can contain a casket. The container wall, the lid wall, and the seal bar flow of matter into the space containing the casket. The container wall and the lid wall both also wholly enclose chambers which am filled with concrete. There is a fenestrated spacer attached between the walls of both the concrete filled container chamber and the concrete filled lid chamber with the concrete passing through the fenestrated spacer to link the concrete filling the container chamber to the container and to link the concrete filling the lid chamber to the lid to give the container and the lid the strength of concrete.

Abstract: An overwidth slitting method slits a metal strip into two lengthwise pieces while trimming the side edges from the strip. The metal strip is placed on parallel spaced apart conveyors adjacent a slitter for conveying the strip to the slitter. The conveyors are raised above a plurality of vacuum cups which are disposed between the conveyors and are spaced along the length of the strip. The raised metal strip is aligned with respect to the slitter and the raised conveyors are lowered to a position where the bottom surface of the aligned strip engages the vacuum cups between the conveyors. A vacuum is applied to the vacuum cups for holding the strip in alignment relative to the slitter and then the metal strip is advanced on the conveyors into the slitter while sequentially releasing the vacuum from each vacuum cup engaged with the bottom surface of the metal strip as it advances. The advancing metal strip is simultaneously slit into two lengthwise pieces while the side edges are trimmed therefrom.
