Lanolin-free lanolin substitute compositions comprising:A) from about 5 to about 95% by weight, of at least one plant sterol fatty acid ester;B) from about 1 to about 20% by weight, of at least one polyglyceryl di-polyhydroxy fatty acid ester;C) from about 1 to about 20% by weight, of at least one polyglyceryl di-fatty acid ester;D) from about 0. The lid includes a shield projecting from its inner surface and located between two electronic components when the lid is closed so that its leading end can abut on a mounting surface on which the two electronic components are mounted. In addition, the optical elements are configured in such a way, that pupil planes of the optical representation paths intersect the reflecting surface of the deflection element or are located at a distance from said reflecting surface. A range setting arm of the system may adjust the total output of the first drive wheel to match the total output of the second drive wheel. The angles are reinforced by two or more webs bent from the plane of the legs and attached, for example by welding, to the intermediate section.
