Abstract: A centering mechanism for maintaining a tunnel structure equidistant from the two parts of an articulated vehicle. The mechanism includes a base plate pivoted to the tunnel structure and having a pair of vertical pins spaced apart on the base plate. Each of the pins accommodates a pair of levers which have toothed portions meshing with tooth portions on aligned levers on the other pin. The levers are connected in pairs to the adjacent chassis member by links so that upon movement of the chassis members about a horizontal axis, equal and opposite rotation of the links occurs to keep the tunnel centered.

Abstract: An articulated vehicle includes a pivotal connection to permit movement between the chassis portions about a vertical and a horizontal axis. To reduce lateral deflection between the chassis portions a torque transmitting linkage is mounted at roof level and comprises a pivoted link mounted on a vertical pin on one of the chassis members. A pair of lateral links extend from the pivoted link to the other of the chassis members. The lateral links are generally parallel and prevent pivotal movement of the pivoted link upon a lateral force being applied to one of the chassis members.

Abstract: A process for the reproduction of oil painting and the like, having a relief surface, using a relief mold taken from the original and a thermoplastic foil, imprinted with a color picture corresponding to the original, the foil being molded while being heated and which includes placing the foil upon the relief mold in a fitting alignment and heating the foil essentially homogeneously to its liquefying temperature across its entire surface.
