摘要： The invention relates to a method according to which the wet scrubbing of a gas flow is performed in at least three, advantageously six successive steps or phases, and the droplet separation of the scrubbed gases is carried out in a uniform cyclone-like droplet separator composed of several nested cylinders. The invention also relates to a method for momentarily bypassing, during a capacity rise, a scrubbing phase that causes pressure loss. As a result, there is obtained a clean and dropless gas that falls below the allowed dust content limits and can thus be either conducted to combustion or discharged in the open air. The invention also relates to an apparatus, a multiphase scrubber, for realizing the method. The invention is particularly suited to be used for scrubbing hot furnace gases from closed reduction furnaces, where said furnace gases contain easily inflammable components.

摘要： A sledge or equivalent transporting base, consisting of a frame (1) and of thereinunder mounted travelling members such as runners (2), with reference to which the frame is movable in the direction longitudinal to the sledge. To the runner (2) has been pivotally attached an arc-shaped rolling member (3) with the center-point of its radius at the pivotal point and which is free to roll along an opposed counterface (5) on the frame (1). With the aid of the invention, sledge runners which have frozen fast to snow or ice can be easily freed by first backing up so that the load rolls into its rear position, whereafter the sledge is started, whereby with the aid of the load's mass the runners are jerked free from frozen-on snow and ice.

摘要： The invention relates to an arrangement and method for heating gases in a gas circulation duct in connection with continuously operated sintering. In the sintering furnace, hot gas is fed in from above the belt in order to sinter the material located on the belt, and part of the gas circulation duct is formed as a burning zone, a burner ring, where the gas is heated. The burner ring comprises at least one burner unit directed inwardly from the circumference of the gas circulation duct.

摘要： A carrying strap for a weapon, attached to the weapon in such manner that it forms a loop intended to be kept across one shoulder and the back, whereby the weapon can be held in front of the person supported by the carrying strap, ready to fire. A drawback of all carrying straps is that the weapon is hanging upside down when in the ready-to-fire position. The carrying strap of the invention has, at least at one attachment point, a laterally stiff strap section so that the center of gravity of the weapon, in correct ready-to-fire position, lies below the line defined by the stiffener and the other attachment point.
摘要翻译：用于武器的携带带，以使其形成用于保持在一个肩部和背部的环的方式附接到武器，由此武器可以被保持在由携带带支撑的人的前面，准备着火。所有携带皮带的缺点是武器在准备就绪的位置时倒挂。本发明的承载带至少在一个附接点处具有横向刚性的带部分，使得武器的重心在正确的准备就绪位置位于由加强件和另一个限定的线之下附件点。

摘要： A multiphase scrubber for the wet scrubbing of gases in several different phases comprises at least three separate basic scrubbing units so that the scrubbing of the gas is carried out in at least three, advantageously six, successive steps. The droplet separation of the scrubbed gases is carried out in a uniform cyclone-like droplet separator composed of several nested cylinders. A clean dropless gas contains a dust content below the acceptable limit. The scrubber is suited for scrubbing hot furnace gases from closed reduction furnaces.
