Patent CA-2337805-A1 (CA)
Inventor: BARKSBY NIGEL
IPC: C08J9/30
Filed: 1999-06-29
Abstract: L'invention concerne des élastomères de polyuréthanne microcellulaires permanents présentant des liaisons urées fortement réduites voire pour ainsi dire inexistantes. Ces élastomères peuvent être préparés sans recourir à des agents d'expansion physique organiques, par moussage d'un mélange moussant contenant des polyols réactifs à l'isocyanate et des prolongateurs de chaîne ainsi qu'un composant isocyanate moussant. On obtient le composant isocyanate en faisant réagir un excédent stoechiométrique de di- ou de polyisocyanate avec un composant polyol contenant un polyol très faiblement insaturé. De manière surprenante, ces élastomères produits par moussage font preuve d'une résistance au déchirement, d'une compression rémanente et d'autres propriétés physiques fortement améliorées par rapport à tous les élastomères microcellulaires de densité équivalente, expansés à l'eau.

Filed: 1993-08-17
Abstract: Window cover systems include window cover material in the form of pleated panels or slats. The window cover material is suspended from a traverse track and is traversed along the track for opening and closing the window system. Arrangements for maintaining spacing and alignment of pleats or slats are provided. The alignment maintaining arrangements include traverse tapes which are substantially rigid in longitudinal and lateral directions in the plane of the tape, and are flexible in a direction perpendicular to the tape. The arrangements also include attaching the window cover material to vertical edge members and providing foldable spacer-members between adjacent edge-members. In one arrangement, a box-pleated panel of window cover fabric is suspended from a traverse track on slide-members. The slide-members are each attached to a spacer-tape at regular intervals along the spacer-tape. The spacer-tape is substantially rigid in the traverse direction and in a vertical direction perpendicular to the traverse direction. The window cover system is opened and closed by rolling and unrolling the panel and the spacer-tape around a roller located at one end of a window frame. Other arrangements include combined, tape-supported vertical slat blinds and vertical pleated drapes in which the tape(s) are supported by sprockets or wheels/pulleys.

Patent CA-2359673-A1 (CA)
Inventor: MEDVINSKY SASHA
IPC: H04L12/22
Filed: 2000-01-28
Abstract: The present invention allows consumer communications device in the figure su ch as an IP telephony adapter (110) to self-generate public key pairs (224) and  certificates (214). This eliminates the need for such keys and certificates to be sent to the devices from an outside source so a single-trust approach can  be maintained. A manufacturer's certificate is installed into a device at th e time of manufacture. The device only issues itself certificates based on a signed request from an external outside server. The device's self-issued certificates incorporate information obtained from the server in a profile. This allows control by the server over a device's self-issued certificates. In order to prevent tampering, and breaking, of the self-issued certificates, t he certificate issuing process occurs within a secure microprocessor.

Title: Method and arrangement for inspection and requalification of lined vehicles used for transporting commodities and/or hazardous materials
Inventor: EUNG MICHAEL
IPC: G01M99/00
Filed: 2000-09-29
Abstract: A test procedure for inspecting a vehicle (100) adapted to transport commodities. This procedure includes the steps of inspecting (S500) a lining  disposed in a tank of a tank car and comparing (S510) crack, blister, and corrosion conditions on the liner with predetermined models. These predetermined models convey a discrete range of severity levels of cracks, blisters, and corrosion conditions and permit determination (S520) of severi ty level for the compared condition(s). The severity level for the condition is  then documented (S530). Standardization of inspection findings facilitates trending analysis of each tank car or vessel lining to determine when requalification of a given lining should be carried out, thus improving the safety with which commodities (including regulated hazardous materials) are shipped and stored.
