Abstract: Un système de communication fixe sans fil (100) est un système téléphonique à ligne fixe ou hybride et un système radiocellulaire hybride. Plus particulièrement, ce système téléphonique fixe sans fil (100) assure une liaison de communication instantanée entre un terminal fixe sans fil (101) d'un utilisateur et un système de communication à fil (105), ce qui permet à l'utilisateur de composer un autre numéro d'utilisateur et de recevoir des tonalités de progression d'appel telle que la tonalité d'invitation à numéroter. Cette liaison est établie par détection (403) d'un signal de décrochage au niveau du dispositif de communication, par transmission (405)d'une demande d'établissement de communication à numéro de téléphone "fantôme" sur le système cellulaire classique, et par la reconnaissance (411) dudit numéro "fantôme", par la demande (413), en réponse à ce dernier, d'une liaison audio sur le système de communication à fil (105) et par la liaison (415) de la liaison audio sur le système de communication à fil avec le dispositif de communication par le système de radiocommunication cellulaire classique.

Abstract: A thrust bearing includes an annular first retainer, an annular second retainer and a plurality of rollers. The first retainer and second retainer are secured together to form a bearing cage. Each retainer has a circular outer sidewall, a concentric circular inner sidewall, and a web that extends between the outer sidewall and the inner sidewall. The web has a planar interior surface with a plurality of openings each adapted to accommodate a radiused portion of one of the rollers. The use of a web with a planar interior surface, without dividers, provides two advantages. The design leaves a maximum amount of room for rollers in the bearing which increases the bearing's capacity. The assembled cage allows for better lubricant flow to lubricate the bearing and wash potentially abrasive particles away from the rollers.

Abstract: A flexible shaft having at least one end formed to have a helical square shape, wherein successive cross-sections have square shapes progressively rotated with respect to each other. The overall rotation from where the square cross-section begins to the adjacent end of the shaft is preferably in the range of to 20 degrees. The helical square end is preferably shaped by swaging utilizing helical square dies preferably made by electron discharge machining. When the helical square end of the flexible shaft is forced into a mating square opening of an end fitting, the helical square configuration of the shaft end causes it to be deformed and bind tightly in the fitting with an interference fit, thus reducing vibration and noise when the shaft is rotated. Instead of a helical square shape, the end of the flexible shaft may alternatively have another helical polygonal shape.
