Abstract: Embodiments may take the form of a perforating gun of modular assembly. The perforating gun may include at least one centralizing member at an interface between a loading tube and a carrier. Among modular components, the gun may also include an initiator assembly module that is electrically coupled to a modular feedthrough with a connector. The insert and the centralizing member may enhance axial cohesiveness of the modular gun. A shock absorbing mount may be located within the carrier and may receiving the initiator assembly module to provide added axial cohesiveness to the modular gun.

Abstract: An article of apparel includes a garment, such as a T-shirt, having a body portion, sleeve portions and an open neck portion. A partially-completed design is placed on the body portion of the garment so as to be externally visible when the garment is worn by a wearer. One or more holes are defined in the body portion of the garment at locations within the perimeters of portions of the partial design which are physically and functionally related to the portions thereof by allowing exposure of the flesh of the wearer through the holes so as to integrate with and complete the design.
