Title: Method and apparatus for the manufacture of mineral wool
Inventor: AASTRAND ERIK
IPC: C03B37/05
Filed: 2003-12-30
Abstract: The invention relates to a method and an apparatus for the manufacture of mineral wool fibres with a fiberising apparatus comprising rotating rotors, in order to form mineral melt into fibres. The first and second rotors of the fiberising apparatus rotating toward each other form an upper rotor pair, and the fiberising apparatus comprises at least one further rotor, advantageously a rotor pair, which is arranged below the upper rotor pair. Mineral melt is fed from a melting furnace or the like in the form of a melt jet toward a first position on the mantle surface of the first rotor, from where it is thrown out from the mantle surface of the first rotor in the form of a drop cascade toward the mantle surface of the second rotor. A first portion of mineral melt is formed into fibres at the second rotor and blown off the rotor, and a second portion of mineral melt is thrown out from the second rotor in the form of a drop cascade. The main portion of that drop cascade being thrown out from the second rotor is arranged to be thrown toward the mantle surface of the first rotor, toward a second position downstream from said first position on the mantle surface. A portion of mineral melt is formed into fibres at the first rotor and blown off the rotor.

Title: Universal slicer with an insertable housing
Inventor: JOZE BARBARIC
IPC: B26D1/143
Filed: 2004-08-26
Abstract: A food slicer has a substantially parallelepiped or approximately cuboid housing with a rear wall and a front wall disposed at a distance from the rear wall. An interspace is formed between the two walls, the space is accessible via a removable housing wall, and it is used to receive a drive unit with a drive motor and a gear mechanism that drive a circular cutting blade at the front wall. In order to provide the housing of such a food slicer with a high degree of rigidity in a simple manner and to create a food slicer which is easy to assemble, the removable housing wall is formed by one of the narrow-sided housing walls and the other housing walls are joined to form a unit, thereby resulting in a very stable food slicer structure.

Title: Servomotor
Inventor: CARRE JEAN-JACQUES
IPC: B60T13/567
Filed: 1980-06-14
Granted: 1984-12-28
Abstract: The servo unit is provided with an internal bracing member which is stressed upon assembly, permitting mounting to a vehicle using only two fixing screws. The bracing member has an initial shape which is curved in a given direction, forming a clearance between the inside face of the mounting wall and two regions of the bracing member against which the skrews bear. The clearance is eliminated when the bracking member is pressed against the inside face at the moment of definitive fixing of the screws w.r.t the casing. The bracing member provides for better distribution over the whole of the inside face of the braking reaction forces which are applied to the casing.
