Title: Time diversity communication system
Inventor: ITO SHOGO
IPC: H04B7/02
Filed: 1995-03-10
Abstract: The probability of receiving signals correctly in a selective radio paging receiver is improved by a time diversity reception scheme. Time diversity reception is therefore applied to both the address signal and the message signal that make up a paging signal. In other words, time diversity reception is performed for each error-corrected or error-detected code word, without distinguishing between the address signal and the message signal, said code words being the units which make up these signals. For example, a received signal comprising correctly decoded code words can be obtained by selecting, from among code words with the same content that have been received over a plurality of times, those code words that are judged to have been correctly decoded in accordance with error detecting logic. Alternatively, by selecting, from among code words that are judged to have been correctly decoded in accordance with error correcting logic, those with the smallest number of error-corrected bits, code words with the least likelihood of miscorrection can be selected from among corrected code words with the same content that have been received over a plurality of times. The probability of correct reception by a selective radio paging receiver is improved by these means. Moreover, when a code word has been correctly decoded, by prohibiting reception during the time intervals when code words with the same content and that are subsequently transmitted would be received, part of the selective radio paging receiver can be stopped from working, as a result of which, battery consumption can be decreased.

Patent CA-2180760-A1 (CA)
Inventor: DUVAL MAURICE J
IPC: B41K1/00
Filed: 1996-07-09
Abstract: Les estampes et les têtes d'estampage sont en général de construction monobloc et entièrement fabriquées de métal (acier dur et résistant aux chocs). Les estampes à un ou deux caractères sont taillées en pointe afin dégager le pourtour du caractère pour éviter un contact de ce même pourtour avec la surface lors de l'opération de marquage. Ces étampes sont toujours monoblocs. Les têtes de marquage sont taillées dans un bloc métallique et reliées mécaniquement à une queue, elles sont monobloc {queue intégrée) pour le marquage manuel. Ces têtes sont gravées sur leur face de marquage ou évidées afin de recevoir des caractères amovibles. A cause des phénomènes dynamiques existants dans le marquage par impact, les têtes de marquage actuelles, généralement conçues pour des applications statiques (travail sur presses), présentent un certain nombre d'insuffisances. De plus le coût de fabrication de la tête (usinage d'un évidement prismatique, traitement thermique de la pièce) est relativement élevé. Dans la présente invention, les éléments métalliques nécessaires au transfert de charge pour le marquage sont incorporés dans un bloc d'élastomère. Le bloc d'élastomère assure un contact précis des caractères avec la surface (perpendicularité); le pourtour grâce à ses propriétés élastiques, pouvant servir d'appui sans affecter le marquage. Le bloc d'élastomère assure le guidage latéral, le parfait alignement des éléments métalliques (queue, barre d'appui et caractères amovibles) ainsi que le contact de ces éléments métalliques entre eux. Cette construction fournit de plus une sécurité quasi absolue au travailleurs en cas de rupture des éléments métalliques. La construction d'une tête pour le marquage sur une surface courbe est nettement simplifiée. Une simple barre d'appui cintrée permet de fournir un appui pour les estampes de sorte que leur surface de marquage épouse la courbure de la surface à marquer.

Title: Method of venting smoke from highrise residential buildings
Inventor: IVISON JOHN T
IPC: F24F7/06
Filed: 1996-12-31
Abstract: In highrise residential buildings, venting to remove smoke from corridors is required in case of fire. In prior art systems, separate supply and exhaust shafts are provided and connected to each floor's corridor through  motor-controlled damper.  A disadvantage of the prior art system is that it thus requires two motorised dampers per floor and an expensive control system and wiring. The invention provides a method of venting smoke from a multi-floor building by providing a single supply and exhaust venting shaft communicating with each floor, with an air supply and exhaust grille opening into each corridor and communicating with the venting  shaft; providing a supply source of pressurized air, and an exhaust source of reduced pressure each communicating with the venting shaft, and damper means for selectively closing or opening the communication of the supply source of pressurized air and exhaust source of reduced pressure to the venting shaft. Under normal conditions where pressure is desired in the corridors, the supply source is operating and the communication of the supply source is open to the venting shaft and the exhaust source communication to the venting shaft is closed.  In case of a fire where venting of smoke or air is desired in at least one of the corridors is desired,  the exhaust source is activated and communication of the exhaust source to the venting shaft is opened and supply source communication to the venting shaft is closed.

Abstract: A connector comprising a body having a body central bore defining a body axis, with one end contoured to conform to the surface of the support member, and another end shape to coaxially abut the free end of the hollow member. Expansion means are carried by the body for close entry into the hollow member when the body and the free end abut. Drive means pass through the body central bore and have one end adapted to engage the support member, and another end engaging the expansion means, to impart a radially outward force component to the expansion means as the drive means is drawn toward the support member. The expansion means can be in the form of resilient fingers cantilevered from the body into the hollow member, and the drive means can be a wedge member drawn by a bolt, toward the support member, for urging the resilient fingers outwardly. In an alternative configuration, the expansion means can be in the form of a metal clip having a plurality of transversely extending prongs, which are preferably arranged such that the cantilevered fingers pass between the prongs to maintain the prong orientation relative to the body axis.  The drive means can, for example, be in the form of a threaded bolt which threadably engages and draws the clip toward the support member such that the prongs are urged outwardly into engagement with the hollow member.
