Patent CA-2151911-A1 (CA)
Inventor: RODE KENNETH A
IPC: F42D1/045
Filed: 1993-12-17
Abstract: An extended delay detonator assembly (1) provides a pre-selected, electronically controlled delay between an incoming non-electric impulse input signal from, e.g., a shock tube (10) or other input transmission line, and detonation of the output charge (44) the energy from which may be used to set off a blasting charge or to transfer the signal to another signal transmission line such as output shock tube (216). In another embodiment, the delay detonator is disposed in a housing (12) closed at one end and opened at the other end for coupling to the input transmission line (10), the signal from which may be amplified by a booster charge (20) mounted within the housing (12). A piezoelectric generator (30) converts the optionally amplified impulse input signal to electrical output energy. A battery-powered programmable electric delay circuit such as that contained in digital delay module (232) is activated by the electrical output from piezoelectric generator (30), counts the pre-selected delay period, at the end thereof ignites an electrically operable output charge (44).
Patent CA-2152213-A1 (CA)
IPC: B21D13/00
Filed: 1995-06-20
Abstract: L'invention s'appelle une PROFILEUSE PORTATIVE. Elle est utilisée dans le domaine de la construction ou de la réparation des revêtements de toiture. Dans ce domaine les couvreurs se servent d'une plieuse à métal qui leur permet de faire sur tous les côtés de divers métaux des plis constituant par la suite un joint vertical entre les deux tôles. La plieuse est d'une longueur de huit (8) pieds. La plieuse ne convient pas puisqu'elle oblige les couvreurs à faire un joint horizontal sur les versants des toitures qui sont dans la plupart des cas supérieurs à huit (8) pieds. La PROFILEUSE PORTATIVE règle ce problème majeur, puisqu'elle permet decréer les joints verticaux sur une longueur indéfinie et élimine complètement les joints horizontaux. Elle fonctionne sur le principe du formage de plis par le passage du métal dans une série de rouleaux. La présente invention constitue une innovation puisqu'elle permet dorénavant de ne plus avoir la présence de joints horizontaux dans une toiture et par le fait même assure son étanchéité. La présente invention est conçue avec un moteur et un régulateur de vitesse. Afin de la manipuler, elle exige la surveillance d'une seule personne. Elle peut profiler à raison d'un pied seconde et elle est munie d'une rampe qui s'installe sur le toit. Il n'y a plus de diverses manipulations pour plier le métal, elle effectue en une seuleopération, le métal profilé. Son principal attrait est qu'elle est relativement légère et elle se transporte sur le site ou la toiture doit être faite.
Patent CA-2154825-A1 (CA)
Title: Dual mode radiotelephone modulator
Inventor: MUCKE LARS H
IPC: H04L27/00
Filed: 1995-07-27
Abstract: A dual-mode frequency and phase RF modulator (11) for use in a transmitter of a radiotelephone.  A dual-mode modulation approach is employed wherein, in the analog (FM) mode of operation, a phase modulator, such as a .pi./4-shift DQPSK modulator,  is bypassed and may be powered down.  A frequency modulated RF carrier is coupled through a bypass circuit (52) to a modulator output   node   (50)   for   transmission   from   the radiotelephone.  In the digital mode of operation, the bypass signal path is disabled, the .pi./4-shift DQPSK modulator is enabled, and in-phase (I) and quadrature (Q) signals are input to the .pi./4-shift DQPSK modulator which provides a phase modulated RF carrier that is coupled to the modulator output node for transmission from the radiotelephone. The teaching of this invention can  be  employed  with  radiotelephones  having,  by example,   TDMA/analog  capability   or  CDMA/analog capability.
Patent CA-2157209-A1 (CA)
Inventor: PEACH ROBERT
IPC: H04B7/204
Filed: 1995-08-30
Abstract: A repeater for a multibeam communications satellite combines the features of coaxial channel interbeam switching and suchannelization of some of the channels. In one embodiment described, the input radio-frequency signals from the input beams are fed through the input multiplexers to form channels. Some, but not all, channels are subsequently subchannelized for interbeam switching. In another embodiment of the invention, a portion of the incoming radio frequency signals bypasses the input demultiplexer and is filtered for noise-limiting reasons, converted down to an intermediate frequency and then subchannelized using SAW filters. The specification also teaches that digital techniques can be used to obtain the same results. Especially in the case of satellites with a large number of beams and a large number of channels, it is not necessary to have full interbeam switching of all the subchannels derived from one channel: instead, the specification proposes the use of parallel configurations of smaller, less complex switching networks.

Title: Adhering chlorosulfonated polyethylene to non-polar polyolefinic elastomers
Inventor: SEXSMITH FREDERICK H
IPC: C09J5/06
Filed: 1994-05-16
Abstract: A method for achieving adhesion between an adhesive composition and a non-polar polyolefinic elastomer. The adhesive composition is based on a chlorosulfonated polyolefin having a chlorine content between about 5 and 30 percent. The adhesive composition is contacted with the surface of the non-polar polyolefinic elastomer at an elevated temperature so as to effect adhesion. The specific chlorine content of the chlorosulfonated polyolefins allows them to be utilized effectively without relying on traditional aromatic nitroso compounds or their precursors.

Filed: 1994-12-13
Abstract: The present invention is a multilayer material for making packages adequate for containing dry materials, which exhibits a superior moisture protection and prevents the migration of greasy compounds through an ethylene vinyl alcohol copolymer barrier layer. This migration, beyond leading stains and poor aesthetics, can jeopardize the strength of the package container. The multilayer material (10) of the present invention is glued together for reforming into a packaging container, and not, as more commonly, heat sealed. To achieve this aim, the EVOH layer (15) is sandwiched between two layers of cardboard or paper (11, 19). The EVOH layer is attached to the two layers of cardboard or paper by tie layers (13, 17) on either side. In this way the cardboard or paper layers of this multilayer material constitute the outermost layers. In reforming said multilayer material into a packaging container, starting from a single blank, the inner part of said container, made of cardboard or paper. can now be glued onto the outer part of said container, also made of cardboard or paper. The present invention does not need therefore more sophisticated assembling techniques, such as for example heat sealing, for the reforming into a packaging carton.

Abstract: Cette invention concerne des procédés de transmission d'informations au système nerveux chez l'homme sans avoir recours aux canaux de perception audiovisuels. Ce procédé consiste à coder des informations en signaux de perception tactiles et à entraîner le sujet humain à reconnaître ces signaux. Les informations primaires sont disloquées en flux individuels qui sont chacun codés sous forme de codes consécutifs discrets. Les codes de chaque flux sont transmis à des éléments distincts les uns des autres et fixés sur la peau du sujet. Lors du processus d'entraînement, on apprend au sujet à pouvoir synthétiser les signaux reçus sous forme d'informations finales qui correspondent aux informations primaires. Les informations primaires sont codées en faisant appel à des signaux ayant des caractéristiques de tension et/ou d'intensité de différentes amplitudes et/ou fréquences, des signaux de vibration mécanique possédant des amplitudes et/ou des fréquences et/ou des localisations différentes, ainsi qu'à des signaux thermiques. La durée des codes et des intervalles de temps entre ces derniers est ensuite modifiée, tandis que l'on règle le rythme de dislocation des informations primaires. Cette invention permet de créer des systèmes de vue ou d'ouïe artificiels, ainsi que de créer un système tout à fait nouveau d'échanges d'informations entre l'homme et la machine. Ce système peut être utilisé dans le contrôle non audiovisuel du fonctionnement d'une machine et dans un dispositif de commande de celle-ci, dans la création de systèmes de communication audiovisuels, dans la création de prothèses adaptatives pour les membres, etc. La particularité de cette invention vient de son caractère non invasif, c'est à dire ne nécessitant aucune intervention chirurgicale, ce qui lui permet d'être utilisée par des individus en bonne santé ainsi que par des individus ayant besoin d'appareils d'assistance.
