Abstract: An at least partially moveable motor-vehicle outer skin is already known per se. An actuator formed of a polymer and/or ion-exchanging and/or other material exhibiting various conformations is provided so that the outer skin can be moved. This material is moveable as a result of physical or chemical effects. The novel outer skin of a motor vehicle requires no expensive tools for the production thereof. The flat section of the outer skin of the bodywork of a motor vehicle is made of a flexible material. A flexible material such as material for convertible top covers is easily moveable yet the surface thereof cannot be increased. This material is tensed at least over one part of the rib of the motor vehicle, e.g. over a space frame. At least one mechanically moveable adjusting element is provided beneath or on top of the edge of the section enabling the outer skin to be deformed. The adjusting element is normally connected to the rib of the motor vehicle.

Abstract: The convertible skate includes wheels that are interchangeable between an in-line configuration and a conventional roller skate configuration. The skate can be readily changed between the different configurations by depressing a first button to release a latch and unlock the front pair of wheels from a first configuration. The front wheels can then be rotated into and locked by the latch at their second configuration. The same type of conversion method and apparatus can be used to convert the rear pair of wheels between different configurations. The skate may also include a reverse spinning brake that prevents the skate from rolling backwards. The reverse spinning brake works in either the in-line configuration or the conventional roller skate configuration without requiring any changeover process between configurations.

Abstract: A lever controlled battery terminal connection, comprising a body having upper and lower portions, said lower portion defining a re-entrant recess to receive a battery terminal post, a lever carried by the body to pivot relative to said body upper portion and relative to said recess, the lever having one pivoted position wherein clamping force is transmitted to the post by the lever.
