Patent CA-2322428-A1 (CA)
Title: Toy vehicle jumpset with crossing rise and descent paths
Inventor: LAMBERT GERARD L
IPC: A63H18/02
Filed: 1999-01-28
Abstract: A toy vehicle jumpset includes a booster (14) coupled to a trackway (11) for receiving toy vehicles (47). The output of the booster is coupled to an upwardly curved, vertical launch ramp (15) which directs the toy vehicles in a vertical rise. An inverted vertical loop (16) is positioned to receive the upwardly directed toy vehicles and redirect the toy vehicles downwardly to a landing ramp (17) in a travel path which crosses the vertical rise path. A return trackway guides the toy vehicles from the landing ramp back to the booster entrance to repeat the cycle. A pair of safety shield sleeves (30, 31) are supported by a tower (20) between the launch ramp and the inverted vertical loop to prevent the user from leaning into the vehicle travel path and risking potential injury.
Patent CA-2325738-A1 (CA)
Inventor: NILSSON MARGARETA
IPC: D21C9/10
Filed: 1999-04-07
Abstract: A method in bleaching of pulp is described, in which the pulp is subjected to a peroxide bleaching step, whereupon the pulp is washed and the washing liquid from the washing is separated from the pulp in the form of a filtrate. The method is characterised in that the filtrate is treated with an aluminium compound, such as aluminium sulphate or polyaluminium sulphate, for precipitation of interfering substances, such as oxygen-demanding organic material and metals, that the precipitated material is removed from the filtrate, that the aluminium content of the filtrate after precipitation of interfering substances is adjusted to at most 20 ppm, and that the filtrate is then recirculated to the peroxide bleaching step. By the method, a reduced consumption of hydrogen peroxide in the peroxide bleaching step is achieved.
Patent CA-2327281-A1 (CA)
Inventor: DOLBY RAY MILTON
IPC: G10L19/008
Filed: 1999-04-05
Abstract: A spatial audio coding system, including an encoder and a decoder, operates at very low bit-rates and is useful for audio via the Internet. The listener or listeners preferably are located within a predictable listening area, for example, users of a personal computer or television viewers. An encoder produces a composite audio-information signal representing the soundfield to be reproduced and a directional vector or "steering control signal". The composite audio-information signal has its frequency spectrum broken into a number of subbands, preferably commensurate with the critical bands of the human ear. The steering control signal has a component relating to the dominant direction of the soundfield in each of the subbands. Because the system is based on the premise that only sound from a single direction is heard at any instant, the decoder need not apply a signal to more than two sound transducers at any instant.

Title: Narrow spectral width high power distributed feedback semiconductor lasers
Inventor: MAWST LUKE J
IPC: H01S5/12
Filed: 1999-03-31
Abstract: High power edge emitting semiconductor lasers are formed to emit with very narrow spectral width at precisely selected wavelengths. An epitaxial structure is grown on a semiconductor substrate, e.g., GaAs, and includes an active region at which light emission occurs, upper and lower confinement layers and upper and lower cladding layers. A  distributed feedback grating is formed in an aluminum free section of the upper confinement layer to act upon the light generated in the active region to produce lasing action and emission of light from an edge face of the semiconductor laser. Such devices are well suited to being formed to provide a wide stripe, e.g., in the range of 50 to 100 µm or more, and high power, in the 1 watt range, at wavelengths including visible wavelengths.

Title: Portable visual instructional aid for coaching sports
Inventor: BOWN DAVID J L
IPC: A63F3/02
Filed: 2001-03-21
Abstract: A portable visual instructional aid for coaching sports involving the use of a simulated miniature sport playing surface and tokens that are used to represent individual players and other sport equipment. The simulated miniature sport playing surface provides a top-view of the sporting field, court, ice rink, pool, or the like. It is constructed from a flexible material that can be easily rolled up or folded for compact storage and transport but when unfurled or opened it quickly assumes a flat state. The playing surface is preferably constructed from water-resistant or waterproof material to permit the instructional aid to be used during wet weather conditions. Tokens are used to represent individual players and equipment used to play the sports. The coach then uses these tokens to setup game situations on the playing surface to teach the strategy and tactics of a particular sport.
Patent CA-2341737-A1 (CA)
Title: Abrasive polishing method
Inventor: RHOADES LAWRENCE J
IPC: C09C1/68
Filed: 1999-08-25
Abstract: The present invention is based on the practice of abrasive machining with no sealed working chamber by the employment of a visco-elastic abrasive medium, behaving predominantly as an elastic solid at the applied.strain of the orbital working motion, and applying orbital or other relative working motion to produce strain rates which bring the medium into a predominantly elastic deformation and often near, but not to exceed, the compressive stress limit at the strain rate employed. The preferred visco-elastic abrasive medium is a rheopectic poly(boro-siloxane) filled with viscosity increasing stiffening agents and high loadings of the abrasive of choice and relatively minor amounts of plasticizers. The system is operated in an open chamber under applied strain rates such that at least about 50 %, particularly about 50 to 99 %, and preferably about 80 to 95 %, of the deflection of the medium under the conditions of operation occurs by elastic deformation and is elastically recovered, and less than 50 %, particularly about 1 to 50 %, preferably about 5 to 20 %, of the deflection of the medium occurs by fluid or plastic flow.

Abstract: L'invention concerne une méthode de production d'une électrode négative pour une cellule secondaire au lithium ayant des couches minces de lithium et un électrolyte solide inorganique à base de sulfide. Dans la méthode, on utilise un matériau à base d'électrode négative et une matière brute électrolytique solide inorganique placés respectivement dans des contenants fermés. Le matériau de base a une surface de métal lithium. Le matériau de base et la matiere brute sont respectivement retirés des contenants fermés dans un espace de chambre, qui est substantiellement inactive au lithium et qui est isolé de l'air et adjacent à un système de dépôt de couches minces. Le matériau de base et la matière brute sont transférés dans le système de dépôt de couches minces sans être exposés à l'air. Dans le système, la matière brute est utilisé, et une couche mince d'une électrolyte solide inorganique est formée sur le matériau de base. Le matériau de base ayant une couche mince est transféré, sans être exposé à l'air, vers un espace de chambre, qui est substantiellement inactif au lithium. Dans l'espace de chambre, le matériau de base ayant une couche mince est placé dans un contenant fermé. Par conséquent, on peut produire une électrode négative sans qu'elle soit degradée par l'air.

IPC: H04H20/76
Filed: 2000-02-11
Abstract: A system and method implemented in an interactive television system for scheduling delivery of modules of interactive television applications from a broadcast station to a receiving station. In one embodiment, the system calculates a start time from a predetermined end time and transmission interval for a module. In other embodiments, a transmission interval may be calculated instead of being predetermined, or all of the scheduling information may be explicitly provided to the broadcast station. The module is packetized and transmission of the packets for the module is begun at the corresponding start time. All of the packets except the last packet are transmitted within the transmission interval (i.e., between the start time and the delivery time.) The greater the transmission interval, the greater the flexibility the broadcast station has to schedule delivery of the packets and modules. The last packet is held until the scheduled delivery time and is then transmitted. Because a module is considered to have been delivered to the receiving station when the last packet is received, the delivery time of the module is controllable to within the limits of the last packet's delivery.
