Patent CA-2233649-A1 (CA)
Title: Procede de mise en oeuvre de plusieurs fonctions de relais et montage a relais multiples configure selon ce procede
Inventor: ROOS STURE
IPC: H01H67/22
Filed: 1996-10-08
Abstract: Pour réduire le coût d'un montage à relais multiples, on utilise une partie commune fixe (6) pourvue d'aimants permanents (7), une partie commune mobile (10) pourvue d'aimants permanents (11) et des bobines fixes (9) à noyaux mobiles (8) à commande magnétique connectés à leur moyen de couplage respectif (12). Lorsqu'on raccorde les bobines à une source de courant électrique, les noyaux (8) se déplacent dans un sens ou un autre selon le sens du courant. Lorsqu'on désire établir un contact électrique par l'intermédiaire du moyen de couplage (12), le courant passe dans une bobine (9') dans un sens et dans les autres bobines (9) dans le sens inverse. Lorsqu'un contact est établi, le noyau (8') est repoussé par l'aimant permanent (7') de la partie fixe (6) et attiré par l'aimant permanent (11') de la partie mobile (10) pendant son déplacement. Le moyen de couplage (12') relié au noyau (8') peut par exemple servir à connecter entre eux des conducteurs de télécommunications. Les noyaux restants (8), attirés par les aimants permanents fixes (7), ne bougent pas bien que la partie (10) émerge de la partie fixe (6) sous l'effet des forces de répulsion agissant entre les noyaux et les aimants (11).

Title: Latch assembly with keyed rose plate for adjustment to doors of differing thickness
Inventor: HURST BARCLAY H
IPC: E05B63/00
Filed: 1998-09-14
Abstract: A latch assembly with a keyed rose plate for quick and easy adjustment to doors of different thickness without the use of threaded components. The latch assembly includes a latch body with an outside end having at least two grooves. The grooves are preferably spaced longitudinally apart from one another by one-half (1/2) the difference in standard door thickness. An outside rose plate has an oblong central opening which allows it to fit eccentrically over the outside end of the latch body. Once aligned with one of the grooves, the outside rose plate may be moved laterally with respect to the latch body to engage in the groove with which it is so aligned. An inside rose plate fits over the inside end of the latch body so that the inside rose plate is free to move longitudinally along the inside end of the latch body. By engaging the outside rose plate in the appropriate groove for the door thickness and fixing the rose plates to one another and snug against the door, the latch body is maintained in the center of the door. The engagement of the outside rose plate in one of the grooves secures the rose plate axially and rotationally with respect to the latch body.

Title: Eeg based activation system
Inventor: CRAIG ASHLEY RONALD
IPC: A61B5/375
Filed: 1997-04-10
Abstract: The invention concerns an EEG based activation system that may be used to turn an appliance ON or OFF. EEG signals have been used for control purposes using biofeedback methods.

Title: Method and apparatus for expanding and conferring a cup shape to the terminal junction segment of bi-axially oriented pipes made of thermoplastic material
Inventor: TABANELLI GIORGIO
IPC: B29C57/08
Filed: 1999-01-13
Abstract: The invention provides for conferring a cup shape to the terminal junction segment (2) of pipes that are bi-axially oriented longitudinally and circumferentially and hence very sensitive to diameter and length reduction through heat, by means of passage into a furnace (4) which heats the segment (2) to a differentiated temperature, increasing towards the end of the segment (2), whose inner diameter progressively drops down to a controlled value, as temperature increases (whilst length is simultaneously reduced, with a corresponding increase in thickness). Preferably then, in an appropriate station (33), an additional heating is executed to a plastic deformation temperature suited to obtain a correct preliminary dilation of the terminal segment (2), introducing a rigid element (34) which acts as inner contrast, thereby inhibiting any retraction thereof. Here the segment (2) undergoes a thickening of the dilated wall both during the introduction of the rigid element (34), and during its extraction therefrom. Such terminal segment (2), dilated and heated, is then easily and rapidly fitted onto a calibration expander (3), itself also heated to such a temperature as to limit heat absorption from said segment (2). Here too the terminal end (2) thickens yet again and takes its shape and, after the possible additional heating to force the terminal segment (2) to adhere spontaneously and perfectly to the underlying expander (3), at least the outer surface of the terminal segment (2), thus shaped, is cooled.
