Title: Hub installing tool
Inventor: NELSEN RICHARD C
IPC: B25B27/06
Filed: 1996-05-29
Abstract: An apparatus and method for installing a hub onto a shaft having an outside diameter and a threaded axial bore is provided. The apparatus includes a threaded screw for threading into the bore, an installer nut threaded onto the screw having an enlarged tool engaging end and a reduced cylindrical extension having a distal end face and an outside diameter. The apparatus further includes an annular bearing removably mountable on the cylindrical extension in an installing position, having a pushing face for contacting the hub and an inside diameter slightly greater than the outside diameter of the cylindrical extension and greater than the outside diameter of the shaft, whereby the pushing face of the bearing does not contact the shaft when the hub is installed onto the shaft.

Patent CA-2182002-A1 (CA)
Inventor: GOOLCHARAN BOYSIE M
IPC: H04M11/08
Filed: 1994-01-25
Abstract: L'invention concerne un système de télécommunication (10) permettant la transmission d'informations vidéo en balayage rapide et en couleurs, d'informations vocales et de signaux de données, par une paire de conducteurs toronnés normalement utilisés pour la transmission vocale et la transmission de données. Le signal est transmis par une paire de conducteurs téléphoniques toronnés (16) sous la forme de signaux à large bande, à une distance allant jusqu'à six mille pieds. On amplifie le signal à large bande reçu de la paire de conducteurs téléphoniques toronnés (16) et on lui applique une impédance proportionnelle à l'impédance de la paire de conducteurs téléphoniques toronnés (16), mais vectoriellement opposée. On obtient ainsi un gain égal à l'unité, et de ce fait, l'affaiblissement des signaux provoqué par l'impédance de la paire de conducteurs téléphoniques toronnés (16) est neutralisée, ce qui permet de conserver fidèlement les signaux vidéo sur un parcours important dans une paire de conducteurs téléphoniques toronnés (16). En plus de la compensation de l'impédance de la paire de conducteurs téléphoniques toronnés permettant de conserver fidèlement les signaux à large bande, différents signaux (vidéo, téléphone et données) peuvent être multiplexés et transmis simultanément par la même paire de conducteurs téléphoniques toronnés (16).

Title: Computerized address location and communication system
Inventor: GRAY KEITH A
IPC: G09B29/10
Filed: 1996-08-21
Abstract: A system for linking common address identifiers, such as street addresses, with standard geographic coordinates so as to locate the address identified and display it on a map. The system includes a searching mechanism in which information culled from address databases is set in a hierarchy of data"tiles" from which such information can be retrieved. Pursuant to either a zip code address input by a system user, or a map view presented on a computer screen, a tile set is selected and analyzed for inclusion of an address identifier input by the system user. An address or addresses selected from the tile set are analyzed for likelihood of matching the address input by the user, and then compared with the original zip code or screen view to confirm inclusion. The address selected as being the most likely match is displayed on the computerized map. In the alternative, the user may select from a listing of likely matches an address to be highlighted on the map. The system is storable on one or more mass storage devices including, but not limited to an optically-readable CD-ROM.
