Patent CA-2249450-A1 (CA)
Inventor: CRIMMINS JAMES W
IPC: H04B10/118
Filed: 1997-03-19
Abstract: A method and apparatus for communicating from a base unit (40) to a plurality of portable infrared devices (48.1-48.8) are described using established communication protocols. The signals are sent along cables from the base unit via stationary infrared receiver/transmitter (RT, 46.1-46.16) modules at infrared carriers in standard transmission and receiving slots to and from the portable devices. The RT modules are distributed throughout a space in the building. Control circuits are used to assure that different infrared carrier signals, originating from nearby RT modules, arrive at any one portable device with a phase difference that does not exceed an acceptable amount. The system also includes circuitry in the base unit to select the best infrared signal detected by several RT modules from any one particular portable device. A hub is described to expand the number of RT modules with which a base unit can communicate.

IPC: B21B39/14
Filed: 1999-03-02
Abstract: An assembly for producing a finished shape for a rod after the last rolling stage of a multi stand steel mill. This apparatus provides an operation for correcting minor surface irregularities and shape distortion of the rod as it exits from the finishing roll stand. The apparatus consists of four rollers mounted in an assembly which resembles a roller entry guide except that the rollers are capable of producing changes in shape of a work product passing therethrough. The orientation of the roller axis is slowly and constantly changed to prevent wear distortion of the rollers which may result when the rollers are required to roll a malformed product from fixed roller axes. The rollers may be driven in some circumstances.

Title: Portable heated appliance with catalytic heater with improved ignition system
Inventor: BONNEMA JAMES V
IPC: A45D1/02
Filed: 1998-03-17
Abstract: A portable catalytically healable appliance (10) is provided. The appliance includes a catalyst support structure (52) to flamelessly combust liquid or gaseous fuel (200) and thereby provide a lower temperature heat source than a heat source that combusts fuel via flame. The fuel is ignited inside the catalytic support structure (52) by a spark electrode (70). The ignition of the fuel inside the structure (52) obviates the need for separate flame arresters. The ignition system includes a piezoelectric device (87) that causes a voltage potential to form between the electrode (70) and the catalytic support structure (52). A spark jumps from the electrode to an interior surface of the structure and ignites the fuel inside the structure, causing a flame to propagate. The flame heats the catalytic structure (52) to an activation temperature, after which the fuel is combusted flamelessly on the surface of the catalytic structure.

Patent CA-2288953-A1 (CA)
Title: Nurse adapter for air seeders
Inventor: MAYERLE DEAN JAY
IPC: A01C7/00
Filed: 1999-11-04
Abstract: A nurse adapter mechanism for an agricultural seeding implement converts an air seeder meter box into a nurse inductor box to convey seed particles to the singulator of a planting mechanism. The nurse adapter mechanism is detachably mounted on the meter box of the air seeder to receive a supply of seed particles therefrom and utilizes the normal air flow for the metering mechanism to effect a nursing of seed particles to a planting mechanism. The nurse adapter mechanism diverts the stream of air into engagement with a pile of seed particles and induce the entrainment of the seed particles for conveyance thereof to the remote planting mechanism. A partition wall divides the nurse induction mechanism into a seed side and an air side. The seed side receives the supply of seed particles from the hopper and allows the seed to pass through a passageway into the air side for engagement by the stream of air. Divider walls are provided to isolate each discharge tube from the other discharges tube so that the planter mechanisms can provide a continuous supply of seed particles. The discharge tubes pass through the seed side of the nurse adapter mechanism in a stacked pair, modular configuration with the respective discharge tubes being adequately separated to permit the passage of seed particles therebetween.

Inventor: SCHWINGHAMMER PAT
IPC: H04W16/32
Filed: 1998-05-13
Abstract: L'invention concerne un système et un procédé d'exploitation d'un système de communications cellulaire. Ce système et procédé maximisent la réutilisation des fréquences, en l'occurrence celle des fréquences porteuses disponibles, ce qui maximise la capacité de trafic du système. L'invention concerne un réseau de cellules extérieures créé par une pluralité d'émetteurs-récepteurs de stations de base connectés à un contrôleur de réseau commun. Ce réseau de cellules extérieures compte au moins un sous-réseau de cellules intérieures en chevauchement pouvant être créé par les mêmes stations de base que les cellules extérieures, ou pouvant être créé en utilisant d'autres émetteurs-récepteurs de stations de base situés à l'intérieur de la cellule extérieure. Deux configurations de réutilisation de fréquences au moins sont appliquées aux cellules, une configuration pour les cellules extérieures et une autre, plus compacte, pour les cellules intérieures. Les cellules intérieures sont définies et limitées par un niveau seuil prédéterminé d'interférence entre voies (rapport porteuse/brouillage), les interférences émanant de cellules intérieures adjacentes opérant sur les mêmes fréquences. L'invention concerne également des unités mobiles capables de mesurer directement à la fois l'intensité du signal reçu (RSSI) et le rapport porteuse/brouillage de la cellule de desserte et des cellules voisines associées. Les unités mobiles établissent des rapports de mesure périodiques et les transmettent au réseau lorsqu'un état d'interférence seuil prédéterminé a été atteint. Le contrôleur du réseau commute alors l'unité mobile sur une des cellules voisines. Le procédé et le système de l'invention peuvent être utilisés conjointement à d'autres techniques classiques d'optimisation de réutilisation de fréquences, telles que les procédés microcellulaires ou de type sous-jacent/à recouvrement.
