Patent CA-2328147-A1 (CA)
Title: Pulley
Inventor: KACHELE BRUNO
IPC: F16H55/50
Filed: 1999-04-09
Abstract: A pulley (1) consists of a pulley basic body (3) [sic] which has a cylindrical outer circumferential surface (8). Sitting on this cylindrical outer circumferential surface (8) is a tire (3), which is of sandwich-like design with regard to its radial extent.  This results in a plurality of rings (13, 14, 15) concentric to one another. The ring (13) which is furthest on the inside in the radial direction and the ring (15) which is furthest on the outside in the radial direction are in each case elastomeric rings, whereas a reinforcing ring (14) is located between them. The elastomeric outer ring (15) is harder than the elastomeric inner ring (13), so that a very abrasion-resistant surface is achieved, over which the rope runs, whereas the elastomeric inner ring (13) provides for adequate resilience. The reinforcing ring (14) is provided in order to distribute the rope load as uniformly as possible over the elastomeric inner ring (13 ).

Patent CA-2328636-A1 (CA)
Title: Air drilling system
Inventor: WALTER BRUNO H
IPC: E21B6/06
Filed: 2001-01-04
Abstract: Down hole Intermittently Rotatable Air Motor is placed above Air Hammer and percussive drill bit. By applying weight on the drill string Air Motor is engaged. Air Motor intermittently rotates the Air Hammer and percussive drill bit at low RPM. By lifting the drill string off bottom, thus eliminating the weight on bit Air Motor is disengaged and a free flow of the compressed air is facilitated through the Air Motor into the Air Hammer and the percussive drill bit. In the Air Motor a closed valve is operatively moved downwards by compressed air flowing down the drill string, the valve when it attains its lower position being opened and being returned under the influence of a spring or other upwardly urging means acting on the valve to its upper position at which the valve is closed thereby to complete the cycle of operations. The valve is so continuously coupled to a torque member that the downward movement of the valve causes turning of the torque member so that during the downward movement of the valve the rotor and the Air Hammer and the drill bit are rotatably driven by the torque member but are not rotated during the upward movement of the valve. During the upward movement of the valve, the compressed air flows through the open valve and continues to energize the Air Hammer and to flow through the nozzles in the drill bit. Valve is prevented from rotating by being engaged on the outside in straight longitudinal grooves while on the inside it is engaged in angular grooves that are on the outside of the torque member. Thrust bearing is protected from the destructive shocks caused by Air Hammer by implementing hard elastomer washers.

Title: Machine for manufacturing paper or board
Inventor: LAAPOTTI JORMA TAPIO
IPC: D21F3/02
Filed: 1999-05-07
Abstract: A paper machine having a double-felted first press nip and a double-clothed second press nip adapted to permit variable positions for press members. The first press nip has a suction zone partially downstream of the press nip, the top felt separating from the bottom felt before the downstream end. The bottom felt then carries the web to the second press, a top felt carrying it to the second extended press nip. A pickup suction roll, arranged in the top felt loop, transfers the web from the first press bottom felt to the second press top felt. The latter bottom felt leaves the suction roll at the downstream end of the suction zone and has suction boxes before the web transfer to the top felt of the second press. Heat-supply devices are arranged outside the two top felts on opposite web sides.

Patent CA-2340984-A1 (CA)
Title: Light with a light-guiding element
Inventor: BOHLE MARKUS
IPC: F21V8/00
Filed: 1999-08-19
Abstract: The invention relates to a light (1) which has at least one light source (4) and a wedge-shaped light-guiding element (3). The face (10) of the light-guiding element situated at the point at which the two wedge surfaces (11, 13) are furthest apart is the light entry surface for the light emitted by the light source (4). The first wedge surface (13) forms an acute angle with the light entry surface (10) in such a way that it reflects the light that is radiated into the light entry surface (10) against the second wedge surface (11). The second wedge surface (11) is the light exit surface of the light-guiding element (3). The wedge shape of the light-guiding element (3) ensures that the light is emitted evenly over the total breadth of the light-guiding element and that the light is emitted from the light-guiding element over an angular range which is suitable for illumination purposes without causing a glare effect for the observer. According to a first aspect of the invention, the light exit surface (11) is also profiled with adjacent elevations and indentations crosswise to the direction of the wedge in order to further improve the radiation characteristics of the light-guiding element. According to a second aspect of the invention, a transparent diffuser (20) is positioned at a distance in front of the light exit surface (11) of the light-guiding element (3). The side of said diffuser facing away from the light exit surface is profiled with adjacent elevations and indentations. The distance between the diffuser (20) and the light-guiding element (3) prevents light from entering the diffuser at any angle, hereby increasing the effectiveness of the profiling.

Title: Codec mode decoding using a priori knowledge
Inventor: BRUHN STEFAN
IPC: H04L1/14
Filed: 1999-08-27
Abstract: A communication system supports multiple source coding/channel coding schemes.  A mode indicator can be transmitted with payload data to inform the receiver of the particular scheme currently being employed. The mode indicator may be encoded using a relatively weak channel coding to minimize extraneous overhead transmissions. To enhance the likelihood of successfully decoding the mode indicator, which has information that is highly important in successfully decoding the payload data, various value likelihood parameters can be calculated and combined to identify a most likely mode. Included in the likelihood (soft) parameters is one parameter which can be calculated based on a model of the mode information's likely value (e.g. Markov model).

Le circuit DSP ou le microprocesseur peut intervenir dans d'autres fonctions des dispositifs de pointage ou de recherche ainsi que dans la fonction de rotation, et peut commander un ou plusieurs dispositifs de pointage et/ou de recherche. Chacun des générateurs BPA comprend un registre à décalage à rebouclage linéaire (LSFR) rechargeable ou son équivalent, un compteur chargeable pointant sur l'état du générateur en question, et un dispositif de commande de rotation pouvant recevoir un ordre de rotation et commander le registre et le compteur de pointage pour faire avancer ou reculer d'une certaine valeur de déplacement. L'augmentation de vitesse est effectuée par la commande DSP. Une table des états LFSR et des numéros d'index correspondants sont conservés en mémoire. Ces états LFSR permettent de subdiviser le nombre possible total d'états possibles. Il convient d'espacer uniformément les états mémorisés autour du cercle BPA. La rotation rapide est rendue possible par le circuit DSP, en deux temps. Dans un premier temps, le générateur BPA est chargé de telle sort qu'il passe directement à l'état le plus proche au moyen de la table. Dans un second temps, la commande de rotation du générateur BPA intervient pour assurer le restant de la rotation.
