Patent CA-2231910-A1 (CA)
Inventor: VAILLANCOURT SYLVAIN P
IPC: B60R7/08
Filed: 1998-05-14
Abstract: PRESENTATION Ici, la particularité fondamentale de mon concept se trouve, non pas basé sur le fait qu'il est innovateur ou encore étranger de sa fonction première... C'est-à-dire pour la protection de documents importants, ou encore, des objets de valeurs. Je dirais qu'il est original par son utilisation exceptionnel. - Pour sa commodité. Alors, mon coffret de sûreté - version petit coffret que l'on retrouve dans les banques - se veut d'être encastrer à l'intérieur d'un siège d'automobile, ou autres véhicules routiers, afin que chaque policier qui intervient dans un grave accident de la route, puisse y avoir accès de façon plus facile à l'aide d'une clé spécialement conçue. - A l'exemple un peu comme cette boîte noire dans les appareils de lignes aériennes (avion) qui enregistre les dernières minutes d'un vol. Mon coffret, procure à tous les policiers, l'identification de toutes les personnes à l'intérieur du véhicule et, par la même occasion les personnes à contacter - donc tous les proches de ces mêmes victimes de la route dans un délai relativement très court. Donc, cela se résume, en quelque sorte, en une économie très appréciable de temps de la part des policiers pour contacter les proches et, par le fait même, des démarches d'identification et de recherches, lors de touts les accidents de la route.

Abstract: In a communications network wherein a central station (CS) is coupled to a plurality of network terminals (T1, T2, T3, T4) via the cascade connection of a common link (L) and respective individual links (L1, L2, L3, L4), and wherein the network terminals (T1, T2, T3, T4) transmit information in a time multiplexed way towards the central station (CS), the central station (CS) assigns timeslots for the upstream transmission to the network terminals (T1, T2, T3, T4) by broadcasting group identifiers (G11, G12, G13, G14). Each group identifier (G12)identifies a precomposed group (G2) of network terminals (T2, T3) which respect a predetermined order for occupying upstream timeslots. In this way, the centralstation (CS) can assign a plurality of timeslots to a plurality of network terminals (T2, T3) by transmission of only one single group identifier (G12).

Title: A service multiplexer with bandwith control and signal source feedback
Inventor: SMITH AVRIL JOY
IPC: H04L12/70
Filed: 1997-01-08
Abstract: A service multiplexer (2) for connecting a plurality of signal sources to a public switched communication network transfers data in the form of asynchronously transferred data cells from a plurality of inputs (4) to an output (6) for connection to the network. The multiplexer (2) includes a bandwidth control unit which receives a bandwidth control signal from the network representative of available bandwidth for transmission of cells to the network and generates feedback control signals for transmission to the signal sources to cause them to alter their data transmission rates in accordance with the available bandwidth. An activity detector coupled to the bandwidth control unit monitors the bandwidth of data received at the inputs. The multiplexer allows ABR  (available bit rate) - commandable signal sources to be linked to a single port of a public network operating on an ABR basis to provide an efficient and fair allocation of bandwidth for each source.

Patent CA-2260040-A1 (CA)
Title: Method and apparatus for indicating a load
Inventor: WAXMAN CORY S
IPC: F16B31/02
Filed: 1997-07-07
Abstract: The present invention provides an innovative method and apparatus for determining continuous, visual clamp load status during tightening and throughout the life of a fastener. The present invention provides a nondeformable element (or in some cases elements) (15) that is suitably configured and positioned within a fastener to amplify the deformation of the fastener as a load is applied to the fastener. In accordance with one aspect of the invention, a lever is connected at an internal pivot point of a cartridge. One end of the lever rests upon an abutment within the fastener, while the other end serves as an indicator. As the fastener is tightened, the fastener will elongate causing the abutment to move away from the lever end.  As the abutment moves, the lever rotates causing the indicator end to move relative to the visual scale which is calibrated to indicate clamping force.  If the fastener loses tension, the fastener will contract, thereby forcing the lever to rotate toward its original position. Assembly and calibration of the device requires the simple, inexpensive process of rotating a cartridge.

Patent CA-2261718-A1 (CA)
Inventor: FICK JAMES R
IPC: A61P35/00
Filed: 1997-07-31
Abstract: The major problem with current direct delivery techniques of therapeutic reagents into solid tumors, especially of cells or large volumes of recombinant DNA reagents or drugs, has been resistance of the tissues to the influx of the fluid and/or cells, resulting in low quantities of the fluid and/or cells penetrating into and remaining in the tumor tissue to be treated.  Increased penetration and/or reduced backflow and diversion through the point of entry, so that more material is introduced into and remains in the tumor, is obtained through the use of a viscous vehicle, most preferably having a similar density to tissue, for the material to be delivered. Preferred materials include solutions or suspensions of a polymeric material which gel or solidify at the time of or shortly after injection or implantation. It has also been discovered that cells such as genetically engineered fibroblasts and keratinocytes can be cultured in the cyst fluid of encapsulated tumors. This provides a means for proliferating genetically engineered producer cells within these types of tumors, increasing the number of cells producing viral particles, which then transduce the surrounding tumor cells with the genetic material, in the preferred embodiment, a lethal gene. A number of different tumor types form "cysts", which contain fluid produced by the tumor cells, including brain tumor cells such as gliomas, and many types of breast, and lung tumors.

Patent CA-2264540-A1 (CA)
Title: Laminated fabric having cross-directional elasticity
Inventor: MORMAN MICHAEL TOD
IPC: B32B5/02
Filed: 1997-09-30
Abstract: Transversely stretchable elastic laminated fabric with cloth-like facings was made by a two-step process. In the first step an inelastic laminate was made by continuously extruding an elastomer sheet between two plies of a fibrous sheet and joining the plies by applying pressure on them between a closed gap niproll assembly.      Two longitudinal slits were made into the laminate. Then the rolls of inelastic laminate so made were taken to an oven and the laminate was unwound and pulled through the oven at an elevated temperature, while tension on the web was increased until the slits necked. The necked laminate was wound up on a takeup roll.      When samples were unwound, surprinsingly they did not grow in width, and they showed good CD-elasticity (elongation and springback). Breathability of the laminate was superior to the laminate formed using an open niproll assembly gap.

Patent CA-2274128-A1 (CA)
Title: A grooming implement
Inventor: O'NEILL KILIAN JOHN
IPC: A46B7/06
Filed: 1997-12-12
Abstract: The invention relates to a personal grooming implement, such as a toothbrush (1), comprising a segmented head (2), wherein the segments (6) are essentially connected to each other only by an elastomer (7), the elastomer preferably being fused to the adjacent segments. In a preferred embodiment the implement is a toothbrush having segments (6) disposed longitudinally along the brush head (2), the segments being connected to each other only by an elastomer which is fused to each segment. The strength of adherence of the elastomer to the segments is such that the head can be repeatedly flexed in each direction without loss of structural integrity. In this manner the use of hinges to connect the segments can be avoided, thus improving the reliability and ease of manufacture of the brush and providing greater flexibility in head design.
