Abstract: A method for the regeneration of spent pickling acids. Said acid is mixed with such a minor quantity of a stronger acid that the losses of said stronger acid are compensated. The mixture obtained is stripped, whereby the weaker acids are vaporized. The vapor phase containing the weaker acids is passed to a condenser. The condensate obtained forms the regenerated pickling acid. The spent pickling acid can also be passed directly to an evaporator in which a solution containing a stronger acid is circulated. The vapor from the evaporator is passed to an absorption column and thereafter to a condenser, the regenerated acid being formed of the condensate from said condenser.

Abstract: A method and a device relating to a transmission ion chamber (11). The transmission ion chamber includes four flat inner ion trapping electrodes (15 to 18) and four outer flat ion trapping electrodes (19 to 22). The transmission ion chamber is inserted in a beam of therapeutic rays. The inner electrodes are completely exposed to the beam, and the ion currents from these electrodes are used to cause the beam to be symmetric with reference to the centre line (14) of the primary collimator inserted in the beam. The characteristic feature of the invention is that the outer electrodes are exposed to the beam, on one hand, and are struck by the shadow of the primary collimator inserted in the beam, on the other hand. The ion currents from the outer electrodes are used to center the beam in relation to the centre line (14) after the beam first being caused to be symmetric in relation to the centre line (14).

Abstract: An optical sensor (10), such as an infrared sensor for detecting overheated wheels or wheel bearing on trains passing along a section of track, comprises an optical system (24) having its receiving optical axis angled (e.g. perpendicularly) to the line of sight of the sensor through a sighting aperture (26). A mirror (30) is pivotally mounted in the line of sight and is movable between a first (operating) position in which it reflects rays travelling along the line of sight to the optical system (24), and a second (aiming) position in which an observer can look through a viewing aperture in the top of the sensor and see through the sighting aperture (26) via the mirror (30). When cross hairs (36) between the viewing aperture and the mirror (30) appear superimposed on cross hairs (38) between the mirror (30) and the sighting aperture (26), the observers' line of sight through the aperture (26) is the same as that of the optical system (24) when the mirror is in the first position, thus permitting the sensor to be aimed accurately and easily at a target. <IMAGE>
