Abstract: A fuel system for a liquefied gas drive system. The fuel system has a liquefied gas tank and a cooling system for the vaporized content of liquefied gas, which comprises a liquid nitrogen tank, a nitrogen pump, a heat exchanger, and a nitrogen cooler, which are connected to each other in a pipework circuit. The heat exchanger is arranged in the interior of the liquefied gas tank. Also disclosed are a vehicle, a plant and a machine, in each case with a fuel system, and a method for cooling the vaporized content of liquefied gas of a liquefied gas drive system.

Abstract: An injection head for injecting fluids into a mixing space is provided, comprising a porous plate with a concave first side, which faces the mixing space, and with a second side, a partition with a first side, which faces the second side of the porous plate, and with a convex second side, at least one fluid supply space, which is arranged between the partition and the porous plate, and a plurality of injector elements, which run through the partition and the porous plate and in each case open with an outlet into the mixing space.

Abstract: An improved headlight or lamp assembly for vehicles which incorporates a lens element bonded to a first reflector element. The first reflector element contains a vertically oriented slot centrally located to receive and retain a second reflector element. The second reflector element is a one piece metal stamping that conforms to the curvature of the first reflector element at its slot and contains a socket for retaining a bulb. Removal and replacement of the bulb is therefore achievable by moving the second reflector element in directions that are transverse to the optical axis of the lamp assembly.
