Abstract: A method for preparing a super-hydrophobic membrane by cleaning a metal mesh by immersion in an organic solvent; subjecting the cleaned metal mesh to a surface modification treatment to increase its hydrophilicity; coating the treated metal mesh with a hydrophobic organic substance; and drying the metal coated mesh for obtaining the super-hydrophobic membrane. The super-hydrophobic membrane obtained thereby.

Abstract: A passenger bicycle seat assembly (20) includes a box plate (30) that secures the assembly (20) to the bicycle (28). A position locking device (44) extends from the bottom of the box plate (30) and engages the frame (26) of the bicycle (28) and prevents movement of the assembly (20) from side to side. The box plate (30) defines a hole (54) that extends through the box plate (30). The hole (54) is disposed adjacent to the rear end (34) of the box plate (30) and secures the box plate (30) to the bicycle (28). The hole (54) encloses and fits the mounting shaft (24) that extends between the operator seat (22) and the frame (26) to prevent movement side to side and forward and backward along the frame (26).
