Patent CA-2315164-A1 (CA)
Inventor: FEIGE FRITZ
IPC: B02C4/10
Filed: 1999-04-19
Abstract: The invention relates to a method and corresponding device for the fine grinding of solid mineral and non-mineral substances, preferably cement raw materials and clinker, by application of moderate to high pressure once or several times followed by disagglomeration of the obtained ground products in the same device. The ground product is extracted by gravimetric feeding in the form of a defined layer from a feeding container, by means of the upper strand, moving in a translatory manner, of an endless plate conveyor which is guided around a drive and deviation tumbler. The ground product is then pre-ground or subjected to other processing pretreatment depending on requirements, for example dried or wetted, and then ground under pressure by an elastically adjusted grinding roller, after which it is disagglomerated in the same device by a high-speed hammering machine.

Filed: 2000-09-05
Abstract: A large format or large surface area structural component of an aircraft, such as an aircraft fuselage shell, includes a skin panel and a plurality of stiffening elements such as stringers and frames. The skin panel is fabricated from a plurality of individual skin sheets that respectively have different material compositions and different thicknesses, and that are welded together along respective butt weld joints to form the skin panel having different characteristics of strength and the like at different locations. The stiffening structural elements such as stringers and frames may similarly be fabricated by welding together individual material strips respectively having different material compositions and/or thicknesses. Alternatively, an integral shell component can be formed by integrally extruding a skin panel with stringer members integrally formed thereon.      With such a fabrication process and resulting structure, there is no need to carry out chemical or mechanical material removal steps, or material addition steps, for providing areas having different skin thicknesses in the resulting structural component.      There is also no need to use skin sheets having the largest possible dimensions, but instead a great plurality of small individual skin sheets is joined together in the manner of a patchwork quilt, so as to provide the particular individual characteristics at each location as required in the finished structural component.

Patent CA-2325021-A1 (CA)
Title: Powder injection system for a detonation spray gun
Inventor: DE JUAN LANDABURU JULIAN
IPC: C23C4/00
Filed: 1998-01-23
Abstract: The powder injection system is com-prised of a dosing chamber (2) which is di-rectly supplied by a conventional powder supplier (7) and communicates with the bar-rel (1) of the detonation gun through a di-rect conduit (5). Thus, the pressure wave which progresses through the barrel (1) en-ters through the communication conduits (5) and, when reaching the dosing chamber (2), is subjected to a sudden expansion which stops the powder supply from the continu-ous supplier (7) and produces the complete fluidification of the powder contained in the dosing chamber (2). The fluidized powder will then be entrained by suction up to the barrel (1) where it resides until the pressure wave generated in a new detonation cycle entrains said powder to deposit it to the sur-face of the part to be coated.

Title: Belt tensioner and method of installing the same
Inventor: FRANKOWSKI MAREK
IPC: F16H7/08
Filed: 1999-09-15
Abstract: A belt tensioner for tensioning a belt for a motor vehicle comprises a pivot shaft (16), a pivoting structure (14) mounted for pivotal movement on the pivot shaft (16), and a pulley (12) mounted for rotation on the pivoting structure. A spring (18) biases the pivoting structure in a direction that moves the pulley mounted on the pivoting structure into tensioning engagement with the belt. A bolt (32) is constructed and arranged to mount the belt tensioner on the motor vehicle engine mount. The bolt (32) is constructed and arranged to be tightened to predetermined exent for installing the tensioner of the motor vehicle, the predetermined extent is the same extent to which the bolt is tightened during normal operation of the tensioner. A clamping structure (24, 36) applies a predetermined clamping force on the pivot shaft after the bolt is tightened to the predetermined extent. The predetermined clamping force is sufficiently large to maintain the pivot shaft in perpendicular relation to the engine mount and prevent tilting of the pivot shaft when the tensioner is moved into installed tensioning engagement with the belt, yet sufficiently small to permit manual movement of the pivot shaft relative to the mounting bolt for adjusting the amount of tension applied by the tensioner to the belt.

IPC: H01J49/38
Filed: 1999-10-13
Abstract: Pendant le fonctionnement d'un spectromètre de masse à résonance cyclotonique ionique à haut champ et transformée de Fourier, le moment faisant suite à l'ouverture du système d'introduction de gaz échantillon à soupape pulsée où se produit la crête de la pression du gaz échantillon dans la chambre à vide est déterminé par la mesure de l'amplitude du courant de pompe ionique. Le spectromètre de masse à résonance cyclotonique ionique à haut champ et transformée de Fourier utilise ensuite ce moment et la période de temps connue pendant lesquels une source d'électrons utilisée pour un événement d'ionisation est parcourue par le courant pour exciter la source d'électrons afin que la crête de la pression du gaz échantillon dans la chambre à vide se situe dans la période de temps connue. Ceci permet à des ions d'être produits pendant la crête de la pression du gaz échantillon et d'obtenir ainsi la sensibilité maximale pendant les mesures.
