Patent CA-2605676-A1 (CA)
Title: Motion restoring intervertebral device
Inventor: CORDARO NICHOLAS M
IPC: A61F2/44
Filed: 2006-04-28
Abstract: A motion restoring intervertebral device includes first and second articulating components positioned between adjacent vertebrae with the articulating surface of the first component being formed by a circular domed convex projection having a first radius. The articulating surface of the second component is formed by a generally concave recess having the first radius in the medial-lateral direction and a second larger sweeping radius in the interior-posterior direction so that the components are capable of rotating against each other in all directions and translate against each other in the anterior-posterior direction, whereby translation away from the center of the first radius will produce device and joint distraction to limit excessive translation.
Patent CA-2607081-A1 (CA)
Inventor: SMITH DAVID M
IPC: B23D59/00
Filed: 2007-10-19
Abstract: A laser module for use with a rotating blade-type cutting device, such as a miter saw. The laser module includes a housing rotating in unison with the saw blade, a power source positioned within the housing for supplying electrical power to the laser generator, and a laser generator control switch selectively connecting the laser generator to the power source. For example, a first laser generator control switch may be a centrifugal switch electrically connecting the laser generator to the power source upon rotation of the laser module at a sufficient speed and a second laser generator control switch may be an on/off switch electrically connecting the laser generator to the power source when in a closed position.

Title: Pyrrolidine derivative or salt thereof
Inventor: HACHIYA SHUNICHIRO
IPC: C07D409/12
Filed: 2006-05-18
Abstract: [PROBLEMS] To provide a compound which can be used for the treatment of a disease associated with a calcium-sensing receptor (CaSR), particularly hyperparathyroidism. [MEANS FOR SOLVING PROBLEMS] It is found that a novel pyrrolidine derivative having an aminomethyl group substituted by an arylaklyl group or the like or a salt thereof has an excellent CaSR agonistic modulation effect and also has an excellent selectivity in the inhibition of CYP2D6 which may cause a drug-drug interaction. Thus, the novel pyrrolidine derivative is useful as a therapeutic agent for a disease associated with CaSR (e.g., hyperparathyroidism, renal osteodystrophy and hypercalcemia).

Title: Sdma for wcdma with increased capacity by use of multiple scrambling codes
Inventor: GOROKHOV ALEXEI
IPC: H04J13/18
Filed: 2006-07-24
Abstract: Systems and methodologies are described that facilitate increasing system capacity in a code-limited WCDMA (e.g., TDD, FDD, ~) wireless communication environment. According to one aspect, a larger code space can be defined by introducing multiple code clusters within a sector, wherein each cluster has a unique scrambling code. Codes within a cluster can have orthogonal Walsh sequences that can be assigned to user devices to facilitate communicating over a wireless network and can overlap with codes in another cluster. The unique scrambling code assigned to each cluster can ensure that duplicate Walsh sequences in another cluster in the same sector appear as a pseudo-noise codes.
Patent CA-2617448-A1 (CA)
Title: Arrangements to detect and respond to disturbances in electrical power systems
Inventor: RUTA JOSEPH W
IPC: G01R19/165
Filed: 1999-08-16
Abstract: A control arrangement and method is provided for detecting and responding to disturbances in electrical power systems. In a preferred arrangement, an integration is initiated that is based on a comparison of actual voltage of a source and a reference voltage. When the integration exceeds a predetermined value, the source is considered unreliable. Also in a preferred arrangement, a determination is made as to whether or not the disturbance is a downstream fault condition. For example, this is useful for applications where a transfer is made from a first source to a second source when predetermined disturbances are detected. In this manner, the transfer of the load to a second source is avoided which would continue the supply of the downstream fault. Additionally, the arrangement distinguishes between various degrees of disturbances to permit appropriate response based on the severity and type of disturbance. For example, a first immediate response, i.e. without intentional delay, is provided for more severe disturbances while a second delayed response is provided for less severe disturbances. The control arrangements transfers the load to an alternate source of power via the use of a high-speed source-transfer switching system that both avoids undesirable current flow between sources and minimizes undesirable transfer delays.

Title: Procede d'extraction de fer sous forme d'hematite d'un minerai contenant des metaux de base
Inventor: WHITE CARL W
IPC: C22B3/16
Filed: 2006-12-13
Abstract: Cette invention concerne d'une manière générale des procédés d'extraction minérale et de traitement de minerai et concerne plus spécifiquement des procédés d'extraction de fer sous forme d'hématite de grande pureté d'un minerai contenant des métaux de base et des procédés d'extraction de métaux de base de matériaux contenant des métaux de base. Un procédé d'extraction de fer sous forme d'hématite d'un matériau contenant des métaux de base consiste à appliquer une étape de lixiviation sur le matériau contenant des métaux de base à pression atmosphérique en l'absence d'un oxydant au moyen d'un lixiviant de façon qu'on obtienne un résidu solide et un lixiviat contenant du fer dissous. Le lixiviant contient un acide et un chlorure. L'acide peut être sélectionné dans le groupe comprenant un acide organique, un acide sulfureux, un acide sulfurique et un acide chlorhydrique. Le chlorure peut être sélectionné dans le groupe comprenant le chlorure de magnésium, le chlorure de calcium, le chlorure de sodium, le chlorure de potassium, le chlorure de fer et le chlorure de lithium. Un gaz de sulfure d'hydrogène formé pendant l'étape de lixiviation est extrait du lixiviat d'une manière continue et mis en réaction avec un gaz de dioxyde de soufre dans une réaction de Claus de façon qu'on obtienne du soufre élémentaire et de la vapeur. Après avoir séparé le lixiviat du résidu solide, on peut ensuite traiter le lixiviat de façon à extraire au moins une partie du fer sous forme d'hématite de grande pureté ainsi que les composants acide et chlorure du lixiviant en vue de leur réutilisation dans le circuit de lixiviation. Le lixiviat ou le résidu solide peut ensuite être soumis à une série d'étapes d'extraction de métaux de base et/ou d'étapes d'extraction de métaux de valeur. On peut appliquer le procédé pour extraire du fer sous forme d'hématite et des métaux de base de minerais de sulfure et de minerais de latérite.

Title: Belt casting machine having adjustable contact length with cast metal slab
Inventor: DESROSIERS RONALD ROGER
IPC: B22D11/124
Filed: 2007-03-15
Abstract: A twin-belt casting machine for casting metal strip. The machine is provided with a casting cavity which includes an upstream fixed casting region, in which the belts are in fixed convergent paths in contact with the cast slab, and an adjacent downstream portion in which the belts are adjustable between alignment with the fixed convergent paths and non-alignment therewith (being less convergent or divergent). When the adjustable portions of the paths are moved outwardly relative to the fixed convergent paths, the belts separate from the cast slab at differing predetermined points within the casting cavity. By adjusting the downstream portion of the casting cavity in this manner, the casting machine can operate at essentially constant throughput for a wide range of alloys while ensuring that the cast slab exiting the caster has a temperature within a predetermined range suitable for further rolling to produce sheet product.
