Abstract: A method and apparatus for identifying porosity in a structure made by an additive manufacturing process in which a laser is scanned across layers of material to form the structure. Pyrometry data comprising images of the layers acquired during additive manufacturing of the structure is received. The pyrometry data is used to generate temperature data comprising estimated temperatures of points in the layers in the images of the layers. The temperature data is used to identify shapes fit to high temperature areas in the images of the layers. Conditions of the shapes fit to the high temperature areas in the images of the layers are identified. Outlier shapes are identified in the shapes fit to the high temperature areas in the images of the layers using the conditions of the shapes.

Abstract: The system and method for forming an ignition sequencer comprising two inseparable portions (a body and an armature) where an armature is articulable with respect to a body to allow for the existence of no less than two distinct stages of the ignition sequence through the articulating motion of the additively-manufactured armature. The ignition sequencer assembly architecture allows for installation of an internal energetic compound while all components are assembled and interconnected. The ignition sequencer assembly architecture allows for installation into a next higher-level assembly using a single, uniaxial, force.

Abstract: A liquid transfer system for transferring liquid from a plurality of containers to a plurality of destinations comprises a plurality of inlet valves. Each inlet valve is operable between an open position allowing liquid from a container to be drawn into the system and a closed position blocking liquid from a container from being drawn into the system. Liquid drawn from each of the liquid containers is delivered to a buffer chamber designed to degas the liquid in the buffer chamber. The buffer chamber leads to a vented feeder chamber that is also adapted to retain a volume of liquid. A chamber connection valve is provided between the buffer chamber and the feeder chamber to allow or block the flow of liquid between the buffer chamber and the feeder chamber. The feeder chamber is connected to a plurality of distribution valves operable to deliver liquid to a plurality of destinations.

Abstract: A corona generator including a body and a first support secured to the body is disclosed. The first support and the body include a plastic. The corona generator further includes an electrode and a second support secured to the body and spaced from the first support. The electrode is mounted to the first support and to the second support. The first support and the electrode are both operatively connected to the body by one or more welds.

Abstract: A pressure fryer having a vessel adapted to cook a food product within a bath of cooking oil. Means are provided for detecting the presence of water in the vessel and the bath and for automatically disabling the heater of the fryer if water is present in such quantity as to create a potentially unsafe condition.
