Abstract: The invention relates to a charger module (1) for an internal combustion engine, comprising a mechanical charger (2) and two charge coolers (3, 4), mounted downstream of the charger (2), for cooling the compressed charge air. The aim of the invention is to reduce the costs for producing such a charger module without impairing the rigidity or structural stability of the charger module (1). For this purpose, the charger (2) and the two charge coolers (3, 4) are inserted in a common housing (5) which surrounds the charger (2) and the two charge coolers (3, 4) at least on the bottom side and on two opposite sides.

Abstract: A gas concentration-measuring device makes it possible to measure gas components in a gas sample. An interferometer, based on a dual-band Fabry-Perot interferometer (1), is provided with a transmission spectrum that can be set by a control voltage (38). The control voltage (38) of the dual-band Fabry-Perot interferometer (1) is synchronized over the course of time with the activation and deactivation of the radiation sources (11, 12).

Abstract: A device for measuring the concentrations of paramagnetic gases in a gas sample has at least one modulatable magnetic flux source, which has an air gap, to which a gas sample can be fed. A controllable power source, for generating current and voltage signals, is coupled with the modulatable magnetic flux source in order to generate a modulatable magnetic flux within the air gap. Two measuring points are arranged at least partly within the air gap. Each measuring point has an electrically controllable heating device and a heat conduction-measuring unit or resistive measuring device. Each measuring point is coupled with a variable power source to heat the heating device to a working temperature. Each measuring point is coupled with a measuring circuit to measure heat conduction measured signals generated by the heat conduction-measuring unit, from which the concentrations of paramagnetic gases, which are contained in the gas sample, can be derived.

Abstract: A gas concentration measuring apparatus is in miniaturized form and permits the measurement of anesthetic gas components. A variable interferometer is provided on the basis of a Fabry Perot interferometer (1) wherein the mirrors (2, 3) can be changed in spacing with respect to each other. The mirrors (2, 3) have coatings which make possible the transmission in two spectral ranges (??1, ??2).

Abstract: A lock cylinder which can be actuated from one side by a knob and from the opposite side by a key, has a locking-member hub and a cylinder core which has tumblers adapted to be positioned by the key. A free passage is provided between a coupling member and a locking-member hub so that the coupling member entrains the locking-member hub only in one direction of rotation and can be freely turned back from the entrainment end position.

Abstract: A drive-rod lock having drive-rods which can be displaced by turning the door handle or the like, and a nut associated with the door handle, which nut, held in its basic central position, can be swung out of said position against spring action in the opposite direction, the lock case bearing a cuff rail which continues beyond the lock case into freely extending cuff rail sections (1') behind which there are guided the drive-rods (48) which so control additional locking members, for instance swivel bolts arranged in the region of the cuff rail sections (1').

Abstract: A drive-rod lock has drive rods which can be displaced by turning a door handle or the like, and a nut associated with the door handle. The nut, held in its basic central position, can be swung out of that position against spring action in the opposite direction. The lock case bears a cuff rail which continues beyond the lock case into freely extending cuff-rail sections behind which there are guided drive rods. The drive rods control additional lock members, for instance swivel bolts, arranged in the region of the cuff-rail sections. These locking members operate both by the turning of the door handle and as a result of release of at least one force accumulator acting on the drive rods. Operation is obtained by means of a release which is actuated upon the closing of the door by the frame, or the like, and for a favorable positioning of the release even with a small depth of the drive-rod lock.
