Abstract: A door guide for a rear door or tailgate of a station wagon with the guide including a first member, fixed to a body portion of the station wagon, having at least one wedge-shaped recess which is adapted to receive a projection of a second fitting member, fixed to the door or tailgate, when the door or tailgate is closed. The second member includes a metallic base body with the projections thereof having, in run-in zones, two opposed recesses. An elastic abrasion-resistant material is applied by an extrusion coating on the base body with a projecting bead-like elevation of material being provided at the projections. The bead-like material is adapted to be at least partly forced into extrusion-coated recesses in the process of closing the door or tailgate.

Abstract: A servo brake system with at least two circuits, equipped with a tandem master cylinder, in which two working pistons are arranged coaxially one behind the other; a transmission shifting device thereby automatically shifts in case of failure of the servo installation to a larger pedal travel with a mechanically applied brake pressure that is reduced within permissive limits; the working piston of the actuating side thereby includes a bore coaxial to the other working piston, in which a plunger piston is guided which is actuatable by the input piston.

Abstract: A breech-closing mechanism for an automatic rifle having a breech chamber and a first locking and stop device comprises a longitudinally movable slide formed with a cam slot, a second locking device rigid with a longitudinally slidably bolt mounted in the slide and rotatable relative thereto. A longitudinally movable locking member is non-rotatably mounted in the slide and a radial cam follower pin is rigid with the bolt and extends through an angled slot in the locking member into the cam slot. The locking member is spring-urged forwardly relative to the slide and is carried along by the slide into engagement with the first locking and stop device. The slide moves forwardly relative to the locking member against the spring force when the locking member is in said engagement until the pin is at the forward end of a longitudinal arm of the angled slot.

Abstract: An installation for preheating the suction mixture of a carburetor internal combustion engine with a heat pipe extending from a place of the exhaust gas line system to a place of the suction pipe system and with a heat-absorption zone, on the one hand, and a heat emission zone on the other; the heat pipe leads from its heat-absorption zone to a lower part of the suction pipe directly adjoining the carburetor outlet and in its heat emission zone partly surrounds with its flat condenser jacket from below the flow channel of this pipe along a wall surface area while leaving free the main part of the pipe cross section.

Abstract: An inflatable impact cushion for passengers of a motor vehicle, which in case of an accident is adapted to be selectively filled with the available gas by the increasing pressure by means of several sequentially triggerable ignition stages depending on the strength of the deceleration; in the starting condition, a portion of the protective cushion is separated off by a seam or the like, while the seam or the like is destroyed by the increasing pressure in such a manner that in the end condition the entire volume of the protective cushion is available.

Abstract: A method and apparatus is disclosed for cooling the interior of a motor vehicle which motor vehicle is powered at least in part by hydrogen liberated from a hydride. Cooling of the interior such as the passenger compartment or cargo area is achieved by using the heat of the interior to supply at least part of the heat necessary for heating the hydride to liberate hydrogen. The apparatus includes, in combination with the interior of a vehicle a hydride container and heat transfer mechanism for transferring the heat of the interior to the hydride container thus cooling the interior.
