Abstract: The invention relates to a battery holder (1) comprising a floor (100) and a frame (200) delimiting a housing intended to receive all or part of a battery. The floor (100) comprises a plurality of profiles provided with male locking members (142) and female locking members (122). The floor (100) varies between: a separate configuration in which the profiles are separated; a snapped configuration in which the male locking members (142) and the female locking members (122) cooperate with each other to oppose a return to the separate configuration and are also movable relative to each other according to a predetermined degree of freedom; a locking configuration in which an interlocking and sealing agent (130) is interposed between the male locking members (142) the female locking members (122) and removes (irreversibly) said degree of freedom.

Abstract: A translationally maneuverable trailer jack track system includes a frame having dual opposing inwardly facing elongated slotted sides. The frame is adapted to mount to a trailer frame between a ball coupler and a trailer. A carriage is mounted inside the frame with opposing side elements, each opposing side element bears on and is movably disposed within one of the dual opposing elongated slotted side elements, where the carriage has a centrally located jack collar and at least one threaded receiving element. A drive screw traverses the frame lengthwise and is threaded through the carriage threaded receiving element, where the drive screw is constrained on one end by a fastening device and has a drive cap on the other end.

Abstract: Corrugated tubing (2) having a smooth or semi-smooth bore, and methods for fabricating such tubing are provided. A length of corrugation tubing (2) can be formed with a filler (4) or liner material inside the tubing. The filler material (4) or liner material may yield one or more improved properties such as reducing head (pressure) loss, reducing friction, sound damping, fire resistance, and corrosion resistance. The corrugated tubing with a smooth or semi-smooth bore can be included in a piping system in which a fitting is connected to the tubing.
