Abstract: Pour la confection manuelle des vêtements,  il est d'usage courant de tailler les tissus en se servant de patrons.  Il est cependant nécessaire de donner au tissu découpé une grandeur supérieure à celle du patron pour coudre les deux pièces, avant et arrière, du vêtement à confectionner.   La marge additionnelle de tissu est délimitée habituellement en traçant sur le tissu une ligne parallèle au patron.  Par la suite, le tissu est découpé en suivant cette ligne.   La présente invention permet de délimiter la marge additionnelle requise en même temps que l'on fait la coupe du tissu.  Il s'agit d'un guide-ciseaux qui est fixé à la lame droite d'une paire de ciseaux au moyen d'un aimant.  Ce guide-ciseaux permet de délimiter la marge additionnelle nécessaire en même temps que l'on coupe le tissu car il est placé entre la lame droite de la paire de ciseaux et la bordure du patron.

Abstract: La présente invention concerne un transducteur électromagnétique amélioré (20) capable de produire plus de puissance par masse qu'un transducteur classique. Cette augmentation de la puissance est rendue possible par la combinaision d'un boîtier spécialement conçu pour cette utilisation, d'un aimant au néodyme (36) et d'une structure à deux bobines (40). Une telle combinaison permet de dissiper la chaleur produite par le transducteur, ce qui augmente son efficacité et sa puissance. De plus, la dissipation de la chaleur se faisant de manière plus efficace, le transducteur peut être plus petit que les transducteurs classiques, tout en étant plus puissant.

The primary cover has a recess therein for an auxiliary module which is disposed in the recess. A secondary cover is disposed on the primary cover for covering the recess when the auxiliary module is disposed therein. In order to secure the auxiliary module underneath the secondary cover in the recess of the primary cover, the module has deposed thereon a locking protrusion which is complimentary with a locking opening in the primary cover. The locking protrusion is flexible and has a longitudinal central bulge so that as the protrusion is pressed inwardly into the opening, the bulge causes the flexible protrusion to reduce diameter due to the presents of longitudinal slots therein until the bulge has passed the opening in which case it springs outwardly toward its normal position thus securing the protrusion in the base. A flexible pull tab is provided for displacement under the auxiliary or secondary cover so that when the auxiliary or secondary cover is removed the pull tab may be tugged upon to remove the module from the primary cover by providing the reverse operation to the insertion operation previously described.
