Abstract: PROCEDE DE MONTAGE SUR UN SUBSTRAT SOUPLE DE COMPOSANTS ELECTRONIQUES MINIATURES A PATTES DE CONNEXION A SOUDER L'invention concerne le montage, sur un substrat souple (6), de composants électroniques miniatures du type "beam lead". Elle a pour objet un procédé de montage consistant, après avoir soudé une première patte de connexion (2) d'un composant (1) sur le substrat (6), à cambrer chacune des autres pattes de connexion (3) du composant considéré (1) pendant leur soudage en appuyant la patte de connexion considérée (3) sur une plage métallisée (5) du substrat (6) au moyen d'une pointe (10) d'un outil de soudage tout en effectuant avec cette dernière pointe (10) un mouvement de rapprochement vers le corps du composant considéré (1) avant de procéder au soudage proprement dit. Grâce à ce procédé de montage, les composants électroniques "beam lead" ne sont plus plaques au substrat avec leurs pattes de connexion en extension mais arqués sur ces dernières, ce qui leur procure une liberté de débattement leur permettant d'absorber les contraintes mécaniques en s'aplatissant plus ou moins sur le substrat.

Inventor: ADESSI ALFRED A
IPC: A63B23/035
Filed: 1991-04-25
Abstract: A multi-purpose exercice apparatus for safely performing weight lifting exercises that eliminates the need for an assistant, comprising a bench (22) that is supported on the floor at both ends, one end of which is pivotally anchored (28) to an elongated U-shaped weight supporting frame (26) which encompasses and surrounds the supported bench (22). The U-shaped frame (26) further includes a vertical support (34, 36) that is attached to a positionable weight lifting handle bar (40). Free weights are mounted on each side (42) of the moveable end (26b) of the U-shaped frame (26).  Because of the length of the longitudinal side members (26a, 26c) of the U-shaped frame (26) extending from one end of the exercice bench (22) to the opposite end, the path of the handle bars (40) is essentially linear. The apparatus provides for maximum efficiency and safety in bench pressing, squatting and other free weight exercises.

Patent CA-2076590-A1 (CA)
Inventor: BOGART FRANK J
IPC: H04M3/00
Filed: 1992-08-21
Abstract: Which call feature module, if any, is invoked in response to a user's input of a feature access code is made dependent upon the context in which the feature request is made, in a call-processing arrangement (200) that uses storeddefinitions of syntax (320, 350) and grammar (400, 410) of the network numberingplan. The syntax definitions are definitions (312) of individual symbol strings,including the feature access codes, and include the string's associated virtual node-point identifier (VNI 334) which indicates the string's influence on feature selections. A VNI (254) resulting from the VNIs of symbol strings included in the entire symbol sequence input by a user serves, along with parameters (1230, 1231, 1232) of the context, as a multi-dimensional pointer into a matrix (1202) of feature numbers (1203). The feature module (205) which corresponds to the feature numberpointed to in the matrix by the pointer is then invoked and executed to provide a corresponding call feature.

Title: Linerless label dispenser
Inventor: BOREALI JEFFREY J
IPC: B65H35/10
Filed: 1993-11-12
Abstract: Linerless labels in a continuous web, in roll form, are dispensed. The roll is mounted for rotation by a vertical shaft, and periodically a drive roller with conveyor tapes wrapped around it is rotated to pull the web from the roll in an amount sufficient to unwind approximately one length of label from the roll. The adhesive face of the web engages the circumferential periphery of the drive roller and the conveyor tapes past the drive roller, the exit roller effecting separation of the leading label from the conveyor tapes. An idler roller engages and tensions the web between the roll and the drive roller, and a knife blade is mounted at about the point that the web leaves the drive roller. The components are disposed so that the web engages at least about 170 degrees of the circumferential periphery of the drive roller, with the adhesive face contacting the drive roller circumferential periphery and conveyor tapes.      First and second optical sensors sense marks on the web to start and stop rotation of the drive roller so as to unwind one label at a time from the roll, and the roll is automatically braked to prevent the roll continuing to unwind when driving action by the drive means is interrupted.
