Abstract: A coupling for two adjacent rail sections of a model railway has a bed member with rails and conductor rail held thereon and downwardly extending projections electrically connected to the rail and conductor rail. A coupling member is arranged beneath the bed members and has two upwardly opening, electrically conductive, elastic, locking elements that engage the extending projections such that projections on adjacent rail sections are mechanically and electrically connected. One locking element comprises upwardly protruding elastic tongues that interlock with the projections, and the other locking element comprises two parallel spring wires, connected by a contact spring and set apart by spacers such that projections are insertable there between. A locking element, on the underside of the coupling member, forms the elastic tongues. A connecting element, resting against the locking element, protrudes on both sides of the coupling member in the form of a contact lug.

Abstract: The driving mirror assembly comprises a carrier and mirror pivotable in relation to a base by motor driven spindles. The carrier is mounted on the base by a universal ball joint and is coupled to the base by a cross piece of spring sheet metal which engages around the universal joint. The spring sheet metal is cruciform in shape so as to have four connecting points, a diagonally opposite plan of points being connected respectively to a pair of posts attached to the carrier and the other diagonally opposite pair of points being connected respectively to a pair of posts arranged on said base.

Abstract: An automobile mirror device comprises a mirror mounted in a carrier which is connected by a universal joint to a base. A threaded spindle, driven by an electric motor, engages a split nut held by a spring steel stirrup pivotally connected to the carrier. When the mirror is tilted by rotation of the spindle to either of its end positions, the thread will disengage the nut by forcing apart the parts of the nut.
