Abstract: The present invention is a doll house that can be assembled and disassembled by a small child. The rooms, once assembled, can be stacked upon each other to form large multiple story houses or stacked beside each other to form castles and palaces. The rooms can be large and have large openings for fitting larger dolls and larger doll furniture. The rooms can be easily disassembled for easier storage. The rooms form structures that are safe for children because the rooms self-locate on top of the lower room section. The rooms also have a locking feature that prevents a room from sliding off a lower room by preventing relative lateral motion. These features make the doll house safe for children to build and play with.

Abstract: A simulated eye assembly capable of being changeable from an opened state to a closed state and vice versa. The simulated eye assembly includes an eye portion, and a driving device assembly. The eye portion includes at least one eyelid, and at least one eyeball. The at least one eyelid is coverable on the at least one eyeball. The at least one eyelid is coupled to and driven to rotate with the driving device assembly. When the at least one eyelid is driven by the driving device assembly to rotate relative to the at least one eyeball to the closed state, the at least one eyeball is substantially hidden by the at least one eyelid. When the at least one eyelid is driven by the driving device to rotate relative to the at least one eyeball to the opened state, the at least one eyeball is exposed and viewable.

Abstract: Apparatus and method for separating and replacing a cap from a shank of a tip of a welding electrode. The cap and the shank form a peripheral hollow joint that is defined by a recessed end surface of the shank and a back surface of the cap. The apparatus includes a guide frame having a recessed portion sized for receiving the tip of the welding electrode. The apparatus also includes a cap withdrawing tool movably mounted on the guide frame. The tool has two facing wall sections each having a wedge that is inserted in the peripheral hollow joint. The wedge is forced against the back surface of the cap and removes the cap from the shank by means of a driving mechanism that moves the cap withdrawing tool toward the tip of the welding electrode that is engaged in the recessed portion of the guide frame.
