Abstract: An apparatus for trapping loose food particles in a deep frying vessel has been developed. The apparatus includes a top plate that has a perforated region that allows the loose food particles to fall into the trap pan which sits off the bottom of the vessel. The top plate abuts the side wall of the vessel and sits over the trap pan. The top plate has an unperforated region over any gap between the trap pan and the side wall of the vessel.

Abstract: The invention represents a novel system for controlling the yield of an explosive charge that enables the explosive yield to be selected or decreased from full-yield detonation incrementally down to low-yield detonation using a continuous linear shaped charge jet spiraled around the main charge explosive and deflagrating a selected portion of the main charge explosive. The spiral linear shaped charge jet initiation system activates and projects a liner in a radial direction across a diameter of the main charge explosive in a spiral around its axis at a preselected deflagration velocity toward a main-charge detonation shock front reducing the main charge explosive.
