Patent CA-2290600-A1 (CA)
Title: Augmentation of electrical conduction and contractility by biphasic cardiac pacing
Inventor: MOWER MORTON M
IPC: A61B/
Filed: 1998-07-02
Abstract: Augmentation of electrical conduction and contractility by biphasic cardiac pacing. A first stimulation phase is administered to the muscle tissue. This first stimulation phase has a predefined polarity, amplitude and duration. A second stimulation phase is then administered to the muscle tissue. This second phase also has a predefined polarity, amplitude and duration. The two phases are applied sequentially. Contrary to current thought, anodal stimulation is first applied, followed by cathodal stimulation. In this fashion, pulse conduction through the cardiac muscle is improved together with an increase in contractility. The technique can also be applied to large muscle tissue stimulation other than cardiac muscle.

Title: Support de presentation d'un bouquet floral et procede associe
Inventor: SILVA RENE
IPC: A01G5/04
Filed: 1999-05-28
Abstract: L'invention concerne un support de fleurs transportable, du type masse de mousse florale (16) pouvant être mouillée, logée dans une enveloppe imperméable à l'eau, ou gaine. Cette masse de mousse florale (16) sert de réservoir de même que de dispositif de couplage. L'enveloppe (12) non seulement entoure le réservoir en mousse mais présente des première (18) et seconde (26) extrémités, opposées et ouvertes. La première extrémité (18) sert d'abord à l'insertion d'une tige coupée (22) porteuse de boutons, fleurs et/ou feuilles, dans une première zone (20) d'implantation de la masse de mousse florale, de manière que la tige coupée ait accès à l'humidité, ce qui allonge la durée de vie des boutons, fleurs et/ou feuilles. La seconde extrémité (26), opposée et ouverte, de l'enveloppe permet d'abord l'introduction d'une tige coupée dénudée (30) dans la seconde zone d'implantation (28) de la masse de mousse florale, permettant à cette masse de mousse, enfermée dans l'enveloppe, de servir d'élément de couplage qui va camoufler le fait que les tiges ont été coupées, de manière que l'apparence globale de la présentation florale simule un bouquet non coupé, à tiges longues, sous la forme d'une gerbe que l'on peut porter dans le creux du bras ou soutenir sur le bras.

Filed: 1998-09-28
Abstract: A baffle structure that includes a generally cylindrical portion and at least one generally linear portion is associated with each roll in a yarn processing. The generally cylindrical portion is spaced a predetermined clearance distance from the surface of the roll with which it is associated to define a generally curved channel about the roll. The generally linear portion of each baffle structure extends toward the other roll, with the generally linear portions overlapping each other to define a substantially linear channel between adjacent upstream and the downstream rolls. The generally linear portion extending from the cylindrical portion of the upstream roll toward the downstream roll has an edge thereon. The edge is disposed within a predetermined close distance of the surface of the upstream roll such that the edge lies within the boundary layer of air able to be generated about the upstream roll. The generally curved channels and the substantially linear channel cooperating to define a pathway that substantially encloses the warp array of yarns as the same is moved over and between the rolls. In operation, a substantially uniform transverse temperature is maintained across the pathway at each point therealong, and at least a portion of the heated air about the upstream roll is stripped therefrom as yarn is conveyed from the upstream to the downstream roll.

Abstract: VA mycorrhiza have growth-retardant activity for Poa annua and may be used to control the growth of P. annua in high quality sport or amenity turf consisting mainly of Agrostis or Festuca species. Strains of VA mycorrhiza selected from genera Glomus, Acaulospora, Entrophosphora, Gigaspora, Scutellospora and Sclerocytis may be used. The VA mycorrhiza is applied to the soil as a formulated product in which the VA mycorrhizae constitute the principal component having biological activity on the growth of turf grass.  Dose rates of inoculum having an MPN of from about 200 To 1000 or more propagules per gram are effective and may be formulated with a clay or other solid carrier. The amount of formulated product applied to the turf may be from about 5 g/m2 to about 1 kg/m2. The infective propagules are selected from fungal spores, mycelium, hyphae, and fragments of mycorrhiza infected roots.  These may be applied to sport or amenity turf, or other grassy area in need of P. annua control, or an area in which high quality turf-grass is to be laid or sown.

Patent CA-2320981-A1 (CA)
Title: Change of service profile of mobile subscriber
Inventor: HOKKANEN TUOMO
IPC: H04W8/18
Filed: 1999-02-12
Abstract: A system for changing the service profile of a mobile subscriber includes a location part (31), an evaluation part (32) and a subscriber connection exchange part (33). Besides these, the home location register contains such indi-vidual subscriber connections for the subscriber, which have a different service profile. The duty of the location part is to find out the location of the mobile station in the network and to give location information to the evaluation part. The information may be e.g. a location area iden-tity, cell identity or switching centre area identity which is used in the public land mobile network.  The evaluation part checks to find out whether the location information has changed compared with the location information received earlier.  If it has, it searches the memory for the cor-responding location information and compares the connection information in the record with the current connection information. If the con-nection information is identical, the process re-mains waiting for new location information. If the connection information is different, the eval-uation logic deduces that the connection must be exchanged for a new one and a connection ex-change operation must be started. This may take place so that the connection exchange part dis-connects the mobile station from the network and reconnects to the network using a new MSISDN number. The algorithms and encryption keys relating to this number it fetches from the memory. The network fetches from the home location register the subscriber information relating to this MSISDN number and along with this also the service profile relating to this number. It is most advantageous to implement the location part, the evaluation part and the subscriber connection exchange part on the subscriber identity module (SIM).
