Abstract: A thin, flexible protective firearm cover is disclosed. The firearm cover can comprise a narrow barrel portion to receive and enclose a muzzle end of a firearm, a butt portion to receive and enclose a butt end of the firearm, and an intermediate portion between the barrel portion and the butt portion. The intermediate portion can have a size-adjustable opening that flexibly expands to allow the firearm to pass through. Reducing the size of the opening draws the butt portion and the barrel portion toward one another to secure the firearm cover about the firearm when the firearm is disposed in the cover. The firearm cover is thin and flexible to provide for compact storage of the firearm cover when the cover is not in use.

Abstract: An adjustable eyewear restraint comprises a first strap having a first adjustment end and a first eyewear coupling end, and a second strap having a second adjustment end and a second eyewear coupling end. The straps are slidably and frictionally engageable to one another to allow adjustment of a length of the restraint by moving adjustment ends of the straps relative to each other. The straps can be slidably interwoven to each other about opening(s) of respective adjustment ends. The opening(s) slidably receive an opposing strap. A strap has a loop, coupleable to eyewear, that comprises first and second edges attached together to form an attachment portion substantially in-line with the first edge. A frictional element is frictionally and slidably coupleable to an earpiece to retain the loop and allow adjustment of a length of an eyewear retainer. Associated systems and methods are provided.

Abstract: An eyepiece shield (10, 10b) for a sporting optic (14, 14b), such as binoculars or a spotting scope, comprises an irregular frusto-conical shell (22, 22b) with a narrower end circumscribing at least one eyepiece hole (26), and a wider end circumscribing an oblong eye opening (30, 30b). The eye opening is non-parallel with the eyepiece hole, and has a concave profile with respect to at least one viewing axis (34) between the holes. The shell comprises a flexible and resilient, laminate material with different inner and outer layers sandwiching an intermediate foam layer. In addition, the shield comprises a fastener (114) with first and second fastener portions (118, 120) carried on opposite sides of the shell at the eye opening to closed the shield with the opposite sides of the eye opening folded in towards one another, and the fastener is fastened with the first and second fastener portions joined together.

Abstract: The present disclosure relates generally to a system for inerting a fuel tank. The system includes a fuel pump, a jet ejector, a first flow path between the fuel pump and the jet ejector, a valve along the first flow path, the valve blocking the fuel flow from the fuel pump to the jet ejector when closed, a second flow path from the ullage of the fuel tank to the jet ejector to allow fuel vapor from the ullage to travel from the ullage to the jet ejector, a vaporizer downstream of the jet ejector and configured to vaporize the fuel received from the jet ejector into the fuel vapor, and a third flow path along which the fuel vapor flows from the vaporizer to the ullage so that an fuel-air ratio in the ullage of the fuel tank is maintained at greater than a flammable fuel-air ratio.

Abstract: The present disclosure relates generally to a system for removing fuel from a mixture of air and fuel vapor in an ullage space of an aircraft fuel tank. The system includes a compressor for drawing the mixture of air and fuel vapor from the ullage space and directing the mixture of air and fuel vapor through a heat exchanger where the mixture of air and fuel vapor is cooled. The system also includes a turbine configured to be driven by the mixture of air and fuel from the heat exchanger. Power from the turbine can be transferred back toward the compressor to assist in driving rotation of the compressor. The system further includes a separator for receiving the mixture of air and fuel vapor from the turbine and separating at least some liquid fuel from the mixture of air and fuel vapor. From the separator, a separated liquid fuel and a mixture of air and fuel vapor with reduced concentration of fuel vapor are returned to the aircraft fuel tank.

Abstract: A cloth accessory and methods for the use thereof are disclosed and described. In one aspect, the cloth accessory may include a cover member forming an enclosure with a cavity therein, and a cloth attached to the cover member. The cloth may have a first configuration wherein the cloth is retracted substantially into the cover member, and a second configuration wherein the cloth is extended substantially out of the cover member without becoming detached there from.
