Abstract: An airbag unit having an airbag and at least one inflator. The airbag unit is especially suitable for preventing an element located outside the passenger compartment of a vehicle from intruding into the passenger compartment during an accident. The airbag is made of a hose formed of a one-pieced woven element extending from a first end to a second end. The hose is bent or folded, such that two parallel sections (24a, 24b) of the airbag are formed with each section (24a, 24b) enclosing a chamber. The airbag is very robust and can be designed such that in its deployed state its thickness is large in relation to its volume.

Abstract: The invention relates to an extrusion device (1) for compacting metal parts, in particular shavings (3), for example made of Fe, Cu, Mg or alloys of these elements or other low melting metals or their alloys, into homogenous extrusion mouldings with at least one extrusion unit with an extrusion die (5) formed by a die housing (9) which forms a die cavity (8) and has a guide arrangement for an extrusion element (7) adjustable by a drive device (6), and with an inlet opening (28) for the shavings (3) in the die housing (9), whereby a compression channel (18) is arranged opposite a front face of the extrusion element (7) facing the mould cavity (8) and adjacent to the mould cavity (8) in the direction of a passage surface (15) for a material strand (2).

Abstract: A protective furnace gas for protecting a bath of magnesium in furnace equipment includes a mixture of inert gas such as nitrogen and 0.3 to 1.5% by volume of SO2, the mixture being provided in a temperature-controlled room wherein the temperature is at least 22° C. and preferably 25° to 35° C.

Abstract: A first sleeve and a second sleeve are put onto the shaft at a predetermined axial distance apart and are pressed radially. The shaft is encapsulated between the first and the second sleeve with a thermoplastic in such a way that a vane body, which has at least one aperture, is formed. The vane body is encapsulated with a sealing compound in such a way that a sealing lip is formed on the vane body at the margins.

Abstract: Inlet pipes extend from a collector to the cylinder inlets of the internal combustion engine. The inlet pipes are formed with mutually facing openings in their adjacent walls. Control flaps each have a shaft, which is respectively provided with a damping element and is mounted by way of the damping elements in a bearing bush. The openings in the inlet pipes are selectively closed and opened with the control flaps.

Abstract: In order to achieve an improved chip and shaving ejection in a portable per, a small portion of the motor cooling air stream is diverted and directed through an air passage into a chip ejection channel. The volume flow of this chip ejection air stream may be controlled by a control slider gate to suit various operating conditions. The chip ejection air stream also serves to cool the drive belt and planing head. The diverted air flow keeps the chips in a sufficiently loose state to assure an effective, clog-free ejection of chips. Furthermore, a deflection flap is used in the chip ejection channel to eject the chips to either side of the tool as desired.
