    摘要: A method of treating cellulose pulp which is subjected to an oxygen-delignification stage (3), a washing stage (4), an ozone-bleaching stage (1) and a further bleaching stage, for instance a peroxide-bleaching stage (7). A gas mixture of oxygen and ozone is delivered to the ozone-bleaching stage (1). The used gas mixture is regenerated, i.e. freed from carbon dioxide, and returned to the oxygen-delignification stage (3) and/or to a bleaching stage (7).

    摘要: The present invention relates to a system for filling an empty flexible container such as an airbag with gas essentially instantaneously when the system or vehicle utilizing such system is subjected to sufficient deceleration forces, such as experienced during a collision. The gas-filled container functions as a force absorbing cushion which protects occupants in the vehicle against injuries. The system includes pressure vessels filled with gas under high pressure, one or more conduits connecting the pressure vessels with the flexible container, provisions for opening the connection between the pressure vessels and the flexible container upon sensing retardation or deceleration forces that exceed some threshold value, a container holding or mixing device, and a retardation meter. The pressure vessels are each sealed by a closure device and each has a respective connection conduit which joins the pressure vessels to the flexible container. One pressure vessel contains oxygen and an inert gas. The other pressure vessel contains inert gas and hydrogen. The inert gas is helium, argon and/or nitrogen.

    摘要: A mixture of noble gases having desirable insulative properties for use as a window fill gas is derived from an air separation process without substantial further separation or concentration of the noble gases in the mixtures. The mixture of noble gases is processed to form the fill gas using relatively economical catalytic oxidation processes and drying techniques to provide a suitable fill gas. The processed noble gas or fill gas may contain from about 89 to 95% krypton, 5 to 8% xenon and 0.5 to 2% contaminants including oxygen, nitrogen, hydrocarbons and other constituents typically found in air separation processing.

    摘要: An arrangement for adding an odorant to a consumer gas which is distributed to a consumer site, in order to indicate to people in the vicinity of the risk of fire, explosion, poisoning, suffocation or some other danger, should consumer gas leak into the surrounding atmosphere. The odorant is dissolved in a condensed vehicle gas in a pressure vessel (3), to obtain a solution, master gas, which includes a liquid phase (6) and a gas phase (7). The consumer gas is diluted with an adapted quantity of the liquid phase of the master gas, which is vaporized prior to being mixed with the consumer gas. To this end, the arrangement includes means (18) for correcting the relationship between the two gas flows during the dilution process with respect to the increase in the concentration of odorant in the liquid phase (6) of the master gas that results from the decreasing relationship between the quantity of liquid gas and gas phase (7) in the pressure vessel. This provides for extremely accurate metering of the master gas. The invention also relates to a method of adding an odorant to a consumer gas.

    摘要: A head which is intended to be mounted on a ladle, is provided inside with refractory material. At least one burner for liquid or gaseous fuel and oxygen gas for heating the melt in the ladle is disposed in the head. The head is provided with retainer means for the burner, by the intermediary of which the burner is axially shiftably disposed in relation to the surface of the melt bath and is rotatably disposed in relation to the vertical line of the burner to the surface of the melt bath. Depending upon the burner output, the burner is adjustable so as to emit the best possible heat transfer from the burner flame to the melt bath and, at the same time, to cause the slightest possible chemical action on the melt bath.

    摘要: A method of attaching a connection piece of metal to a metal surface by brazing wherein the required heat is generated by an electric arc. The heat generated by the electric arc is conducted through at least a portion of the connection piece and melts a brazing metal provided between the connection piece and the metal surface. The heat conducting portion of the connection piece prevents direct contact between the electric arc, the metal surface and the brazing metal during melting which prevents disadvantageous thermal actuation of the metal surface. When the current to the electric arc has been disconnected, a mechanical force is applied to the heat conducting portion of the connection piece pressing the latter against the metal surface and pressing out a portion of the brazing metal from underneath the remaining joint-forming surfaces of the connection piece.
