20160006306 | Magnet-Bearing Moving Part for Permanent Magnet Synchronous Machine - The moving part, designed to move past a fixed rotor with coils, comprises a metallic chassis to which magnets, arranged in parallel rows of alternating polarity, are bonded. Non-metallic fixing strips, screwed to the chassis, are positioned longitudinally between each row of magnets, extend along the entire length of these rows and mechanically immobilize the magnets. Each fixing strip comprises a bearing base with convex rounded flanks which immobilize the magnets vertically and collaborates with a concave rounded portion, formed in the adjacent edge face of the magnets over at least half of the height thereof. The strip also comprises a longitudinal upper extension acting as a spacer between the rows of magnets and immobilizing the magnets laterally. The invention is of benefit to the manufacturers of rotary or linear electrotechnical machines such as motors or generators. | 01-07-2016 |

20110011421 | DEVICE FOR CLEANING A FOOD CUTTER GRATING DISC - This invention relates to a device for cleaning a grating disc used for cutting food. The grating disc has two sets of parallel blades, the blades delineating quadrilateral-sectioned spaces in a main plane of the grating disc, a main plane of each blade being substantially perpendicular to the main plane of the grating disc. The device has at least one tooth, the tooth being sized such that it is able to be inserted into the spaces delineated by the blades. The device including a pin aligned with the tooth or teeth, an end of the pin protruding relative to one end of the tooth or teeth. The pin being capable of sliding into a space delineated by the blades at the same time that the tooth or teeth are inserted into one or more spaces delineated by the blades. This invention also relates to a set for cleaning a grating disc, comprising such a device. Finally, this invention relates to a method for cleaning a grating disc used for cutting food. | 01-20-2011 |
