Abstract: An orthodontic appliance has a cylinder with a spring urged plunger therein. The spring is compressed when the plunger is moved into the cylinder: and, one end of the cylinder and the extending end of the plunger are attached between the teeth to be moved. The attachments to the teeth allow universal motion so the jaw is free to move in all directions anatomically possible. To extend between the upper and lower teeth, the cylinder can be slidable within a second cylinder. The second cylinder allows greater extension of the appliance while maintaining the integrity of the appliance.

Abstract: A method and apparatus for displaying, to the driver of a vehicle (12, 14), an introductory or other portion of messages received by a mobile communications terminal (50) of the vehicle.  The message display method may be implemented in a system which includes one or more vehicles (12, 14) in communication with a central control station (18). At least one of the vehicles (12, 14) is equipped with a mobile communications terminal (50) for communication with the central control station (18). In a preferred implementation, the mobile communications terminal (50) is coupled to an internal data link (92) of the one vehicle, to which is also connected a display device (102) in view of the vehicle driver. A first message packet is generated, at the central control station (18), for use by the vehicle driver.  The first message packet is then transmitted from the central control station (18) and received by the mobile communications terminal (50). In a preferred embodiment, an introductory or other portion of the first message packet is provided to the display device (102) by way of the internal data link (92). This advantageously allows the vehicle driver to be apprised of the contents of incoming messages even without direct access to the mobile communications terminal (50).

Title: Dispositif de retenue d'une tige pourvu d'elements de contact positionnables, separes, servant a mesurer la tige
Inventor: OSBURN ANDREW W
IPC: B05C1/08
Filed: 1996-06-06
Granted: 2004-01-27
Abstract: Un corps métallique rigide est placé en aval d'un applicateur de revêtement. Ce corps supporte une pluralité d'éléments de contact positionnables, formés dans un matériau présentant une haute résistance à l'usure et un frottement réduit, ces éléments s'étendant vers l'intérieur à partir du corps et venant en contact avec une tige tournant à faible vitesse. Au moins un des éléments de contact peut être réglé pour soutenir la tige afin que celle-ci ait une rotation stable, et pour retenir un joint efficace se trouvant entre les éléments de contact et la tige, ce qui évite au fluide de clarification/lubrification de fuir et de pénétrer dans le revêtement qui a été appliqué. Les éléments de contact peuvent avancer vers l'intérieur au fur et à mesure de leur usure et de celle de la tige, ce qui prolonge la durée de vie du dispositif de retenue de la tige. Des vis peuvent être placées en appui contre un élément de contact arrière de façon à traverser des plaques support segmentées, ce qui permet de réduire le poids du revêtement dans la largeur du substrat. De plus, une conduite d'air peut être positionnée entre le corps et un élément de fixation arrière en vue de régler l'épaisseur totale du revêtement.
