A method of manufacturing a fluidic actuator that comprising generating a member that includes a web and a pair of cavities and closing the cavities by closing one or more respective openings of the cavities to generate a first closed bladder and a second closed bladder.

A line system for connecting a liquid intake assembly to a liquid tank including a first fluid line for conducting a first fluid, a second fluid line for conducting a second fluid, the first and the second fluid lines being connected in an area between their respective first and second end by a connecting structure extending between the first and the second fluid lines, the connecting structure being integrally connected both with the first as well as with the second fluid line, at least one section of the first fluid line and one section of the second fluid line being arranged fluidically in parallel to each other, and the connecting structure having a fastening formation embodied in one piece with the first fluid line and a counterpart fastening formation embodied physically separately from the fastening formation and in one piece with the second fluid line.

A blow molded article of manufacture includes first and second battery enclosures each having respective first and second laterally outward extending flanges, and a parison made of a polymeric material. The first and second battery enclosure components are disposed facing each other and with their respective first and second laterally outward extending flanges registered with each other and spaced apart from each other by an offset. The parison is sandwiched between and connects together the first and second battery enclosure components, such that the parison conforms with interior surfaces of the battery enclosure components and with the parison substantially filling the offset. The article of manufacture may be cut along a cut line through the parison and within the offset around an outer perimeter of the article of manufacture, thereby separating the article of manufacture into first and second battery enclosure assemblies. Methods of formation are also disclosed.
