Abstract: The invention relates to a vehicle seat with a back rest having a frame (2) and a lordosis support (6), with the following additional configuration: The lordosis support (6) comprises a pressure plate (9) that is essentially bend resistant in at least the transverse direction of the seat or the Y-direction, forms a supporting surface in the lordosis region of the back rest and is arranged between two side frame parts (3) of the frame (2); there is at least one holding element (5a, 5b) that extends between the side frame parts (3) with a length-variable adjustment section (21), which runs in the Y-direction and connects to the pressure plate (9), and is affixed there at fixing points (30) arranged opposite each other; in an inoperative position, the pressure plate (9) is arranged with a horizontal clearance (11) or a clearance in the X-direction behind the fixing points (30); there is a driving device with which the length of the adjustment section can be shortened as the horizontal clearance is reduced.

Abstract: The invention relates to a headrest system for a vehicle seat. The headrest system includes a headrest supported by at least one holding rod, a guide component which can be secured in a backrest of the vehicle seat and is configured to accommodate the holding rod, a first electric connector disposed on a free end of the holding rod, and a second electric connector which cooperates with the first electric connector and can be secured in the backrest. The joining direction of the first and second electric connectors runs approximately coaxially to a central longitudinal axis of the free end of the holding rod. Each of the first and second electric connectors includes at least two contact elements, each of the contact elements designed in a rotationally symmetrical manner in relation to the central longitudinal axis.

Abstract: The invention relates to a headrest system for a vehicle seat, said headrest system comprising a headrest (1) supported by at least one holding rod (3), a guide component (5), which can be arrested in the backrest (11) of the vehicle seat and serves for receiving a holding rod (3), a first electric connector disposed on the free end (10) of the holding rod (3) and a second electric connector, which cooperates with the first electric connector and can be arrested in the backrest (11), the joining direction (42) of the two electric connectors running approximately coaxially to the central longitudinal axis (19) of the free end (10) of the holding rod (3), and each of said two electric connectors comprising at least two contact elements designed in a rotationally symmetrical manner in relation to the central longitudinal axis (19) or the joining direction (42).

Abstract: Disclosed is a method for the production of synthetic fuels, wherein, in a first step, a gas mixture consisting of methanol and/or dimethyl ether and/or another oxygenate and water vapor is reacted at temperatures of 300-600° C. in order to form olefins with, preferably, 268 carbon atoms. In a second step, the olefin mixture thus obtained is oligomerized at an elevated pressure to form higher olefins with predominantly more than 5, preferably 10-20 carbon atoms. According to said method, a) the production of olefins in the first step is carried out in the presence of a gas flow which essentially consists of saturated hydrocarbons which are separated from the product flow of the second step and returned to the first step, and (b) the production of olefins is carried out in the second step in the presence of a flow of water vapor which is separated from the product flow of the first step and returned to the first step.

Abstract: A vehicle seat with a headrest for a vehicle is formed from an impact cushion and installed upon a seat back. The headrest is pivoted around a stationary pivotal axle aligned transversely to a longitudinal axis of the vehicle and can be swung from an unused position against the force of a spring into a used position. In the used position, the headrest is held stationary by a toggle linkage, which, within its self-limiting swing zone, acts as a pivoting element between the impact cushion and the pivotal axle.

Abstract: A headrest adjustment assembly is disclosed for adjusting the position of a headrest relative to a seatback. The headrest adjustment assembly includes a guide disposed in the seat back, at least one holding bar disposed within the guide, the guide and holding bar being configured with sufficient clearance to allow selective relative longitudinal and transverse sliding, the holding bar being fixed to the headrest, and a clamping element mounted to the seat back for selectively applying a transverse force to the holding bar to thereby fix the position of the holding bar within the guide and prevent relative transverse or longitudinal sliding.

Abstract: What is described is a method and an installation for the simultaneous production of methanol synthesis gas, ammonia synthesis gas, carbon monoxide and carbon dioxide from natural gas, in which several plant elements (or plant units) are serially arranged one by one in one single production chain, whereat these elements comprise: a first reactor A, in which the natural gas is transformed under oxygen supply into a synthesis gas mixture comprised of carbon monoxide, carbon dioxide, hydrogen and steam (water vapor), a second reactor B, which allows to control the transformation of carbon monoxide into carbon dioxide, optionally a compressor C for compressing the generated gases, an absorber D for the absorption of carbon dioxide and for obtaining the carbon monoxide-hydrogen mixture used for methanol synthesis, a low-temperature separator E, in which ammonia synthesis gas is obtained by introducing liquid nitrogen, and in which simultaneously carbon monoxide, argon and methane are removed.

Abstract: This invention relates to a process as well as a burner for producing carbon monoxide, in which liquid hydrocarbons such as e.g. oil or natural gas are non-catalytically decomposed into carbon monoxide (CO) and hydrogen (H2) at high temperatures. The steam previously used as atomizing and cooling medium is replaced by carbon dioxide, which downstream of the reactor system is separated from the synthesis gas produced and recirculated. To reduce the expenditure of apparatus for providing the gasification medium, the carbon dioxide is withdrawn from the succeeding gas washing, supplied to the burner and expanded through one or more nozzles directly before the orifice opening for the fuel, the differential pressure of the expansion of the carbon dioxide only being 2% to 50% of the reactor pressure.
