The invention discloses a casing buckling induction brace with a mixed sunken type induction unit. The casing buckling induction brace comprises end restrained sections, a buckling induction section, an inner casing and an outer casing. The buckling induction section is clamped between the inner casing and the outer casing. The inner casing and the outer casing are each connected with one end restrained section. The buckling induction section comprises at least one mixed sunken type induction unit in the axial direction of the brace. According to each single mixed sunken type induction unit, m same mixed sunken type subunits are arranged sequentially in the circumferential direction to form a space body with the section of an m-edge shape. Each mixed sunken type subunit is a space body formed by folding two trapezoidal plates and eight triangular plates which are located in the same plane. The casing buckling induction brace maintains elasticity under the action of a small earthquake, the buckling induction section enters a yield stage under the action of a medium earthquake or a large earthquake, and the good hysteretic energy consumption performance of the casing buckling induction brace can also achieves an effect of a damper.

Embodiments for a fuel filter are provided. In one example, a diesel fuel filter comprises a header having an inlet port, an outlet port, a recirculation inlet port, and a recirculation outlet port; and a filter body made having different material than the header, the filter body coupled with the header and housing a filter membrane. In this way, electrostatic discharge may be reduced.

The invention discloses a sleeve buckling induction brace with a circular spiral type induction unit. The brace is composed of an end constraint section, a buckling induction section, an inner sleeve and an outer sleeve.
