Patent CA-2275281-A1 (CA)
Title: Emergency call initiator
Inventor: BALACHANDRAN SHRIDHARAN
IPC: H04W4/90
Filed: 1997-12-15
Abstract: A system and method for enabling emergency call initiations in response to the detection of a vehicle accident is disclosed. A number of sensors (10) located about the vehicle, for example, air bag deployment sensors, initiate call activation signals upon detection of a vehicle accident. The emergency call activation signal is transmitted to an associated cellular telephone unit (15) via wireline or non-wireline communications, and a timer (35) initiates a timeout period. Once the timer (35) has measured the proper timeout period, an emergency call setup is begun. The emergency call setup may be discontinued at any point by a user abort command (115). Otherwise, the mobile switching center (65) serving the cellular telephone (15) is alerted to initiate an emergency call. The MSC (65) utilizes location information from the base station (60) of the cellular telephone (15) and emergency information (68) from the home location register (70) of the cellular telephone (15) to contact and provide an emergency operator with emergency information.

IPC: B01F7/00
Filed: 1998-01-06
Abstract: L'arbre d'un rotor (40) traverse axialement un cylindre (24) intérieur délimité par un carter (22). L'arbre (40) est monté tournant par l'une de ses extrémités. Un courant de matière de consistance moyenne est introduit axialement dans le cylindre tandis que des produits chimiques de blanchiment sont introduits axialement par un orifice sur un rotor monté sur l'arbre (40). La tête (54) du rotor (50) comporte des passages constituant une turbine qui renforcent la force de percussion des produits de blanchiment dans le sens radial, lesquels sont ainsi répartis sur la totalité de l'ouverture du cylindre. Des ailettes fuselées (62) partant du rotor (50) près de la tête (54) de rotor créent des tourbillons circulant qui mélangent les produits de blanchiment à la pâte. Comme les ailettes (62) fuselées s'étendent radialement en direction des parois (24) cylindrique, du carter (22) les tourbillons s'étendent jusqu'auxdites parois. Les produits de blanchiment et la pâte, intimement mélangés, sont ensuite poussés dans un cylindre (28) perforé séparant l'intérieur du carter cylindrique (22) d'une volute (26) de sortie par des ailettes (62) s'étendant quasiment jusqu'au cylindre perforé (28). Ce dernier (28) présente une "porosité" d'environ 10 % et les trous qui y sont percés ont un diamètre voisin du pouce (2,54cm). Le cisaillement produit entre les ailettes radiales fluidifie la pâte et lui mélange complètement les produits de blanchiment.

Title: List output viterbi decoding with crc outer code for multi-rate signal
Inventor: BAR-DAVID AYAL
IPC: H03M13/09
Filed: 1998-03-20
Abstract: A method and apparatus for decoding a frame of multi-rate encoded digital data which contains redundant information provided to validate the decoding operation. A frame of data is received which contains information bits and cyclic redundancy check (CRC) bits. In accordance with the invention, the received frame is decoded and a check is conducted to determine whether the CRC bits correspond correctly for the decoded information bits. If the decoded frame passes the CRC test process, the decoded frame is provided to the user. However, if the decoded frame does not pass the CRC test, then at least one additional decoding process is performed on the received frame. In the first exemplary embodiment of the present invention, on a failure of the CRC check, the data is decoded using a trellis decoder (224) and the data that yields the next most likely path through the trellis is selected. In a second illustrative embodiment, if the CRC  test fails, the trellis decoder (224) then identifies all paths having metrics within a predetermined threshold of a metric associated with the optimal path through the trellis. The CRC test is then performed on the decoded frame with respect to the suboptimal paths (starting with the most likely path). If any of these paths pass the CRC check, the information bits are output by the decoder (224). If not, an error is declared.

Title: Water-injection nozzle assembly with insulated front end
Inventor: SEVERANCE WAYNE STANLEY JR
IPC: H05H1/28
Filed: 1999-11-26
Abstract: A nozzle assembly for a plasma arc torch includes inner and outer metal nozzle members and an annular insulating element press-fit between the inner and outer nozzle members so that the nozzle members are electrically insulated from one another and bores of the nozzle members are coaxial. Additionally, the annular insulating element is constructed such that the inner and outer nozzle members are secured together to define a water passageway between the interior surface of the outer nozzle member and the exterior surface of the inner nozzle member. The nozzle assembly may further include an outer insulating element secured onto the exterior surface of the outer nozzle member, in which case the annular insulating element between the nozzle members may not be press-fit to the nozzle members. The annular insulating element may define at least one port for introducing water into the water passageway. The port extends in a direction that is generally tangential to an imaginary circle around the longitudinal discharge axis so that the water swirls in the water passageway. Alternatively, the nozzle assembly includes an annular insulating swirl ring press-fit between the inner and outer nozzle members. The swirl ring is displaced along the longitudinal discharge axis from the first annular insulating element and is positioned between the first annular insulating element and the bore of the inner nozzle member.

Title: Coupling communications signals to a power line
Inventor: RICKARD ROBIN PAUL
IPC: H04B3/56
Filed: 1998-10-02
Abstract: A power line communications system has a power line (40) having a plurality of conductors (B, R, Y) which carry communications signals. A set of communications signals are coupled to a set of the plurality of conductors, each signal being coupled to a respective one of the set of conductors and the phasor relationship of the set of communications signals is chosen such that radiation of communications signals from the power line is minimised. The phasor relationship may be achieved by phase shifting one or more of the signals. This method allows communications signals to be transmitted at higher power levels, thereby extending range of transmission, while minimising radiation from the line.

Title: Central hauling pool
Inventor: LOLAND GEIR
IPC: B63B/
Filed: 1998-10-26
Abstract: The invention concerns a central hauling pool (1) e.g. for a fishing vessel, with the central hauling pool (1) constituting a generally vertical main tube (2) through the vessel, with a free lower opening or mouth (8) towards the sea and a free upper opening (4) towards the atmosphere. The novel and characterizing feature of the invention is that the upper part of the main tube (2) has a tube transition (5) constituting a large relative widening of the cross section area below the water line in the main tube (2) to an upper tube part (3). The effect of such a widening of the upper part of the central hauling pool is that the oscillations of the water surface are damped considerably as compared to the heave of the ship and the waves of the sea.
