Abstract: A fire hazard is automatically detected and a fire is prevented or extinguished in an automotive vehicle upon such vehicle being involved in a collision. The vehicle has an air conditioning system including a container and employing CO.sub.2 as a refrigerant. The occurrence of a collision is detected by an impact sensor. In response to detection of the collision by such a sensor, a processing/control unit opens a valve in a line connected to an outlet at or near a bottom of the container. Thereby, the CO.sub.2 refrigerant is released substantially in liquid phase from the container and passed through the line and is discharged as a fire extinguishing agent into various parts of the vehicle, for example the engine compartment.

Abstract: An apparatus is disclosed for horizontal direct chill casting of light metals, especially magnesium and magnesium alloys. The apparatus includes tundish for containing molten metal and a horizontally disposed mold in communication with the tundish. The mold has a primary cooling circuit for cooling mold walls such that the metal is chilled without any direct contact with the water. Also, a secondary direct cooling circuit is provided. The circuits for primary and secondary cooling water are independent of each other. An insulating transition ring is arranged at the mold entrance. It is important that the total mold depth is short, preferably between 25 and 45 mm. To obtain good surface quality and to avoid discoloring of the metal, it is preferred that the mold has an inlet for supplying protective gas to the transition ring. The inlet opening to the mold should be asymmetrically arranged, nearer the bottom of the mold.

Abstract: A tubular member having integral exterior protrusions is manufactured by providing a hollow element, for example by extrusion, having therein an axially extending interior defined by a surrounding wall having a thickness varying circumferentially. Such hollow element is positioned within a die that has therein lateral voids. The hollow element within the die is subjected, at the interior thereof, to an axially sequential deformation, for example by sequential penetration through the interior by a mandrel. This results in a non-elastic flow of the material of a thicker portion of the wall in lateral directions thereof into the voids in the die. This results in the hollow element, being formed into a tubular member having on the exterior thereof solid protrusions.

Abstract: The invention provides a new feed product, especially a fish feed product in the form of pellets or particles, with high fat content and superior physical properties. The product is made by immersing feed pellets in a first hot oil bath with a temperature higher than 100.degree. C. to secure drying of and simultaneous fat absorbtion. This treatment is followed by a cooling in a warm oil bath kept at a temperature of 40.degree.-60.degree. C. This completes the fat absorbtion and results in a dry product consisting of hard and smooth particles with high fat content, which are free flowing and do not agglomerate.

Abstract: A method and tool for installing a baffle in a tubular member, such as a heat exchanger manifold. The method and tool are adapted to use a baffle having a closed base that acts to obstruct the flow of a fluid within the tubular member, and further having a sidewall extending axially from the perimeter of the base so as to form a recess in the baffle. The tool is generally composed of a sleeve having an elastically and radially deformable end, such as a number of cantilevered members adapted to be elastically bent radially outward. Radially outward deformation of the sleeve enables the sleeve to securely grip the baffle, maintain the orientation of the baffle during its insertion into the tubular member, and then plastically deform the sidewalls of the baffle in order to secure the baffle to the wall of the tubular member.

Abstract: A ring section furnace for the calcination of carbon bodies, has a number of chambers (K1-Kn) in which the carbon bodies are placed when performing the calcination process. During the calcination process, a part of the furnace comprising a minor number of chambers is divided into a preheating zone (K3-K2), a combustion zone (K7-K14), and a cooling zone (K8-K10) that together in a successive manner, are advanced relative to the furnace.
