The invention relates to a method for isolating polyhydroxyalkanoates from production cells which comprisesi) disintegrating the production cells, subsequentlyii) separating off the cell fragments from the polyhydroxyalkanoate grains by means of a continuous jet separator;iii) the concentrated polyhydroxyalkanoate grains are washed with an aqueous alkali solution and theniv) with an aqueous acid. This invention provides the ability to carry certain unique weapon shapes that can not be carried on current ejector racks due to the lack of access to the rack once the weapon is raised into position. The heat spreaders are positioned under the LED module. The upper electrode is located over the substrate and the upper electrode is composed of several electrode locations and has several openings, wherein each opening exposes the corresponding doped region.
