Abstract: An Adjustable Pressure Suit Torso, which is a combination of a flexible pressure suit attached to rigid rings, in an assembly of rigid rings and brackets. The rigid rings form openings configured to receive the head, limbs and entry way of a wearer. These rigid rings are attached to one another by brackets, thereby forming an assembly of rigid rings and brackets. The flexible pressure suit is attached to the rigid rings, and otherwise constrained upon pressurization by the rigid ring and bracket assembly. The brackets can be offered in different sizes or made adjustable so as to vary the overall size of the rigid ring and bracket assembly. The flexible pressure suit can be provided in the largest possible wearer size (99th percentile male) and any excess in the flexible suit when donned by a smaller wearer can be folded up while still constrained by the ring and bracket assembly.

Abstract: A novel Adjustable Pressure Suit Torso manufactured from a combination of rigid metal or composite components and flexible textile and membrane materials has been developed. It offers many advantages over primarily soft or rigid approaches to the construction of torso components used in pressure suits such as space suits or high-altitude flight suits. The Adjustable Pressure Suit Torso comprises a series of rigid rings as openings for the limbs and head to extend into from the torso, rigid brackets that are fixed between the rigid ring components, and flexible materials that span the area between the rings to act as a pressure vessel. The brackets have specific sizes and can be easily exchanged to resize the torso to fit a wide range of users. The loading imparted on the pressure suit from operation or pressurization is reacted by the rigid components.

Abstract: The invention provides a renewable composite filter media for removal of particles from a fluid stream comprising a membrane filtration layer comprising a porous polymeric membrane having an upstream side and a downstream side relative to the direction of fluid flow, a first depth filtration media layer having an upstream side and a downstream side relative to the direction of fluid flow, the first depth filtration media layer being disposed on upstream side of the membrane filtration layer; and at least one additional depth filtration media layer removably attached to the upstream side of the first depth filtration media layer. In this aspect, the first depth filtration media layer may be removably attached to the membrane filtration layer.
