Abstract: Un champ magnétique alternatif généré par un électro-aimant très puissant (1, 2) ou par un aimant rotatif provoque un courant de signaux indicateurs dans les fils d'un câble (3) à examiner. On surveille le signal indicateur en l'une des extrémités du câble (3) ou en ses deux extrémités à l'aide d'un récepteur (4) relié aux fils du câble. Le signal indicateur reçu est amplifié et renvoyé par un radiotéléphone au point de transmission, où on l'écoute pour détecter la position du câble et, le cas échéant, un défaut dans une section de câble. Selon l'invention, on envoie entre les fils du câble (3) une tension directe suffisante pour créer un courant dont le circuit se ferme lorsqu'il traverse un emplacement défectueux (9), le signal indicateur étant alors séparé du courant produit par cette tension directe.

Abstract: Un appareil de mise en plis permanente dans lequel des radiations infrarouges sont utilisées afin de chauffer les cheveux concurremment avec une composition de mise en plis permanente jusqu'à une température de 100°C. Le chauffage des cheveux se réalise par l'enroulement des cheveux sur des gabarits à génération d'infrarouges. L'appareil permet d'effectuer une mise en plis permanente après une durée de chauffage de seulement 5 à 60 secondes. Des solutions relativement diluées de la composition de mise en plis permanente sont nécessaires, ce qui élimine le besoin de neutraliser les cheveux après la mise en plis. Ainsi, l'utilisation de l'appareil permet d'effectuer une mise en plis permanente des cheveux en trente minutes environ.

Title: Circuit de prechauffage pour lampes a fluorescence
Inventor: MUEESSLI DANIEL
IPC: H05B41/24
Filed: 1990-10-26
Abstract: En vue de supprimer les inconvénients des circuits de préchauffage de types connus montés sur des ballasts électroniques traditionnels, inconvénients selon lesquels ceux-ci consomment inutilement du courant et produisent de la chaleur pendant toute la durée de mise en circuit du ballast, il est proposé, conformément à l'invention, un circuit qui est coupé après allumage de la lampe à fluorescence (FL). La résistance sensible à la température (PTC22), branchée en série avec un condensateur à égalisation de potentiel (C32) est montée en parallèle par l'intermédiaire d'un condensateur à circuit oscillant de série (C22), conjointement avec une première diode (D1) et reliée, par l'intermédiaire d'une seconde diode (D2), à une sortie haute tension (''+'') du ballast (EGV11). De cette façon se trouvent chauffés, dans une première phase après mise en circuit du ballast (EVG11), d'une part le filament incandescent (W1, W2) de la lampe à fluorescence (FL) et , d'autre part, la résistance (PTC22) de faible valeur ohmique à l'état froid, de telle manière que cette dernière prenne une forte valeur ohmique. Il s'ensuit que si aucun courant d'allumage ne circule entre les filaments incandescents (W1, W2), la tension entre ces derniers augmente jusqu'à l'obtention de la tension d'allumage de la lampe. Après allumage de la lampe à fluorescence (FL), la tension entre les filaments (W1, W2) décroît jusqu'à atteindre la tension d'allumage. Etant donné que cette dernière est plus faible que la tension à la sortie haute tension (''+'') du ballast (EVG11), il ne peut s'écouler à partir de celui-ci aucun courant par la résistance (PTC22). La première diode (D1) empêche que le courant circule, à partir de la sortie ''out'' du ballast (EVG11), par la résistance (PTC22).

Title: Transducteur cylindrique piezoelectrique produisant ou detectant des vibrations asymetriques
Inventor: OWEN THOMAS E
IPC: H01L41/113
Filed: 1990-09-12
Abstract: Un transducteur (10) se compose d'une enveloppe cylindrique (12) et d'au moins d'une paire de sections piézoélectriques (14a et 14b). Chaque élément de la paire de sections piézoélectriques (14a et 14b) est lié rigidement à la paroi du cylindre (12), dans une position diamétralement opposée à celle de l'autre élément de la paire. Le fonctionnement en tant que transducteur de source acoustique est possible par alimentation électrique de chaque section piézoélectrique (14a et 14b) de manière à provoquer l'allongement et la contraction des sections piézoélectriques (14a et 14b), respectivement déphasées l'une par rapport à l'autre, sur la longueur du cylindre (12). Cela provoque une courbure avec flexion dudit cylindre (12), la courbure étant asymétrique par rapport à l'axe (12y) du cylindre. Lorsque l'on utilise une paire de sections piézoélectriques (14a et 14b) de cette manière, le transducteur (10) se rapproche d'undit pôle acoustique, et si l'on utilise plus d'une paire, le transducteur (10) peut servir à se rapprocher dedits pôles acoustiques polarisés d'ordre supérieur. Divers modes de réalisation de l'invention sont particulièrement utiles, soit comme source soit comme détecteur acoustique dans des trous de sondages remplis de liquide, destinés à des applications géophysiques.

Abstract: A granules syringe, particularly for impregnating granules of a bone cement with blood and for dispensing the impregnated granules, includes a transparent tubular barrel for receiving the granules between a porous front cover and a porous plug. A piston which is separate from the plug and has an integrated seal is disposed behind the plug. When the piston is retracted, the seal is closed so that the vacuum is generated to suck the blood through the porous cover into the granules. When the piston is subsequently advanced, the seal opens so that air has been removed from the granules and passed through the porous plug is permitted to escape rewardly. Upon removal of the cover, the plug is then advanced by the piston to dispense the impregnated granules.

Abstract: A container assembly which is especially adaptable to form a final presentation enclosure is constructed from a flat blank (30) of material. The flat blank is provided with a plurality of fold lines forming a bottom wall (32), side walls (34, 36, 38, 40) and the top wall portions (48, 50, 52, 54) which act in conjunction with one another to enclose a space. The side walls are connected by joining portions constituting bellows-type folding members (42). The container is constructed in accordance with the normal hand movements of a person assembling it, wherein the joining members (42) are initially easily folded inwardly thereby drawing up the respective side walls to which they are attached. The natural grasping movement of the hands is then used to complete assembly. The container does not utilize tabs, glue or other fastening means normally associated with a variety of containers. The top walls are formed so as to be exposed at the top of the container to allow securing of the top wall portions by any suitable means. There is also provided a variable volume container by means of the joining members which extend into the interior of the container. The joining members act to center and protect a smaller item within the container or can be completely moved to make available the total volume of the container.
