Abstract: A rope edge protection system having a rope protection mat, an edge protection mat, and/or a replaceable abrasion pad in combination for the protection of rope. The rope protection mat is a generally rectangular sheet that may be secured in a sleeve-like configuration around a climbing rope and move along the rope with the user. The rope protection mat and/or replaceable abrasion pad are configured to be replaceable after it is sufficiently worn down from use. The replaceable abrasion pad is configured to be laid flush overtop the edge protection mat. The edge protection mat is a generally rectangular sheet that has one or more frictional sections positioned on a bottom side that add resistance to horizontal force vectors to the edge protection mat during use. The edge protection mat is a multi-layer sheet with a high loft layer to decrease the bend radius of the rope across a ledge.

Abstract: A new and innovative high-pressure priming valve is provided for use in high-pressure fluid systems that require a high level of fluid purity. The priming valve includes at least three ports, some of which are angled. The priming valve also includes a needle that variably blocks and unblocks a pathway to one of the ports between normal operation and a priming operation, respectively. The priming valve includes a sealing insert positioned below a stack of washers that maintain the needle's alignment in response to high fluid pressures exerted on the needle. The sealing insert helps prevent fluid from contacting the stack of washers, which helps prevent biological growth within the valve. The angled ports help facilitate priming valve drainage to further help prevent biological growth. By helping prevent biological growth, the sealing insert helps prevent fluid contamination and enables the priming valve to be utilized for high-purity fluid applications.

Abstract: An abrasion testing apparatus with a base, a test platform, a pair of angle adjustment wheels disposed on opposite sides of the test platform, a drive wheel, a tension control wheel, and a plurality of idler wheels. The test surface can be raised or lowered and the pair of angle adjustment wheels can be moved toward or away from the test platform to change the angle of contact between a material on the test surface and a material being moved by the drive wheel. The tension control wheel is movable to control the tension of the moving material during the test. A method of testing abrasion resistance involves placing a first material on the test platform and threading a second material around the drive, idler, tension control, and angle adjustment wheels, and in contact with the first material and moving the second material against the first material.

Abstract: The knot protector protects ropes and knots from ledges, rocks, railings, edges, walls, cliffs, and other surfaces that may cause the fibers of the rope to be gradually abraded or destroyed. The knot protector includes a sleeve formed from an upper portion, a lower portion, and a shoulder portion. The upper portion defines a first opening while the lower portion defines a second opening. The diameter of the first opening is smaller or less than that of the second opening. The sleeve is formed from a deformable, continuous web and has exterior and interior layers. The sleeve also contains visual safety indicators along the base of the lower portion to provide visibility. The exterior and interior layers are made from durable material to provide the rope with ample protection from abrasion.

Abstract: A rope edge protection system having a rope protection mat and an edge protection mat in combination for the protection of rope. The rope protection mat is a generally rectangular sheet that can be secured in a sleeve-like configuration around a climbing rope and move along the rope with the user. The edge protection mat is a generally rectangular sheet with loops on each corner, but not limited to the corners, to secure the sheet in place against a building or other structure. The edge protection mat is a multi-layer sheet with a high loft layer to decrease the bend radius of the rope across a ledge. Both the rope protection mat and the edge protection mat include visual safety indicators.

Abstract: An edge protector mat is formed from a mat with a top surface, a bottom surface, and a number of metal bars. The top surface contains a number of receptacles grouped into one or more pairs sized, shaped, and otherwise configured to receive opposing ends of the metal bars therein. Each of the metal bars define opposing ends, different ones of which are positioned within corresponding ones of the pair of the receptacles of the top surface. The metal bars are configured to prevent friction from being imparted onto the mat. At least one pair of the receptacles are positioned opposite one another on the mat allowing receipt of different portions of at least one of the metal bars.

Abstract: A convertible backpack that can be used as an edge protection mat to protect ropes against abrasion and includes a flexible mat or sheet that can be configured into a pack and carried on the back of a user to carry equipment, clothing, or other gear. A pair of rope protection members are affixed to the outer surface of the sheet for carrying the pack and are easily removable for use alone or in combination with the flexible sheet to further protect ropes.

Abstract: The present application provides new and innovative high-pressure fluid systems for preventing seal burning due to gas auto-ignition. The provided systems include an o-ring disposed within a seal cavity of a cup seal to decrease the dead volume in the seal cavity. By reducing the dead volume, the o-ring decreases the volume of gas that is able to accumulate and thus helps prevent the gas from auto-igniting as the gas is compressed. By preventing the gas from auto-igniting, the provided system helps prevent seal burning, which helps prevent premature cup seal failure and prevent fluid contamination.

Abstract: A removable marine cover for protecting marine support structures such as bullnoses in addition to nautical lines from abrasive contact has a polymeric cover body including an outward surface attached to a material with a gripping portion is provided. The marine cover has a set of ratchet straps arranged around the periphery to securely attach the cover to the marine support structure. The inward surface may include a wear pad, and may further include a polyurethane coating to reduce the coefficient of friction experienced by the nautical lines while also protecting the support structure from degradation, which ultimately prevents damage to both the support structure and the nautical lines.

Abstract: A fender hook is disclosed that is formed by a base material carrying a gripping material disposed between sections of hook and loop material. By wrapping the base material over upon itself, the gripping material is brought into frictional engagement with a mounting substrate such as a nautical railing and is held in place by the hook and loop material.

Abstract: A rope cuff including a plurality of shoring lines attached to an interior surface and covered with an interior flap formed from a material with a high coefficient of friction is provided. The shoring lines are braided around a mooring line to serve as a chafe guard and the interior flap frictionally engages the mooring line to maintain both the chafe guard and the cuff in appropriate positions. An adjustable hook and loop strap is attached to the exterior surface of the rope cuff to constrict the cuff around the mooring line and provide further frictional engagement between the interior of the rope cuff and the mooring line.
