Abstract: Floor underlayments, floor underlayment systems and related methods are provided herein. A floor underlayment sheet can include a middle body portion having first outer face and a second outer face with the middle body portion having a thickness. The floor underlayment sheet can also include a first end portion extending outward from the middle body portion from a first side of the middle body portion. The first end portion can have an outer face that aligns with and is contiguous with the first outer face of the middle body portion and an inner face that is opposite the first end portion outer face. The floor underlayment sheet can further include a second and portion extending outward from the middle body portion from a second side of the middle body portion. The second end portion can have an outer face that aligns with and is contiguous with the second outer face of the middle body portion and an inner face that is opposite the second end portion outer face.

Abstract: A safety system for a fluid conduit having: a hose; a first housing connected to the hose with an internal cavity having a first connection point and a first check ball opening cavity; a second housing connected to the hose with an internal cavity having a second connection point and a second check ball opening cavity; a perforated retention tube positioned longitudinally within the hose and in communication with the first connection point and the second connection point; a first check device contained within the first check ball opening cavity and interposed between the perforated retention tube and the first check ball opening cavity; and optionally a second check device contained within the second check ball opening cavity and interposed between the perforated retention tube and the second check ball opening cavity.

Abstract: A safety system for a fluid conduit having: a hose; a first and second housing connected to the hose, each housing having a first and second opening and an internal cavity having a first cavity and a first recess; a perforated retention tube positioned longitudinally within hose; a first valve seat disposed in the first housing and a second valve seat disposed in second housing; a first valve body pivotally attached to the first housing at a first pivot point and having a first tab protrusion protruding through the perforated retention tube and a second valve body pivotally attached to the second housing at a second pivot point and having a second tab protrusion protruding through the perforated retention tube.

Abstract: In a preferred embodiment, an engine coolant crossover assembly includes a crossover conduit member carrying an integral liquid cooled alternator and liquid cooled exhaust gas recirculation valve. The integration of one or both of these parts into the coolant crossover eliminates many parts from the total assembly. These parts include; attachment brackets, coolant hoses, hose clamps, cast mounting blocks, coolant tubes and attachment bolts. Reduction of these parts reduces system costs, assembly time, mass and potential coolant leak paths. A temperature sensor and a thermostat housing may also be included in the crossover assembly. The assembly may also be made part of an intake manifold for an integrated air fuel module of a V-type engine.
