Patent CA-2524121-C (CA)
Title: Drill gripping device and method
Inventor: TJADER MICHAEL
IPC: E21B19/16
Filed: 2004-01-09
Granted: 2012-12-18
Abstract: A drill gripping device is shown with an inexpensive and compact design. In one embodiment, an inexpensive and more compact design is possible through the use of a single actuator with a single gripping portion of a drill gripping device. Embodiments of drill gripping devices shown are further reduced in price and size due to a force amplification device such as a camming arm.  Alternatively, an increased gripping force is possible using an existing size actuator. A drill gripping device is shown with increased precision in gripping. A pair of gripping jaws are synchronized to improve jaw centering capabilities.

Title: Methode de formation d'essieux avec sections de paroi epaissies a l'interieur
Inventor: BUCHOLTZ DENNIS
IPC: B21C25/06
Filed: 2006-02-23
Granted: 2009-08-25
Abstract: Le présent extrait concerne une méthode de formation d'essieu ou tube à épaisseur de paroi variable avec sections de paroi épaissies à l'intérieur, qui comprend l'extrusion de flan de métal tubulaire dans une matrice allongée. Un emporte-pièce allongé pousse le flan à travers la matrice. L'emporte-pièce a une extrémité mettant en butée et poussant le flan dans et à travers la matrice, et une partie allongée qui est séparée de la surface de paroi intérieure de la matrice. Le mouvement de l'emporte-pièce en poussant le flan fait partiellement extruder le flan vers l'avant à travers la matrice jusqu'à ce qu'il soit arrêté, puis extruder vers l'arrière autour de la partie allongée de l'emporte-pièce à travers l'espace pour former un tube. Une bague tubulaire est alors introduite dans le tube extrudé à un endroit prédéterminé et est fixée en place pour donner une section de paroi de tube et paroi de bague combinée épaisse, qui s'étend radialement vers l'intérieur du tube. Il est possible d'utiliser un grand nombre de bagues espacées pour permettre des sections de paroi épaissies espacées dans le tube. Les bagues peuvent être préformées avec une épaisseur de paroi variable autour de leur circonférence pour faire varier l'épaisseur des sections de paroi combinées autour de la circonférence du tube.

Title: Grouping application protocol data units for wireless transmission
Inventor: ADAMS NEIL
IPC: H04W28/06
Filed: 2006-05-24
Granted: 2012-11-13
Abstract: A system comprises a wireless-enabled device that communicates with a wireless- enabled smart card reader to obtain information from or perform operations using a smart card. Commands to access information from a smart card may be sent from the device to the smart card reader, and responses from the smart card may be sent from the smart card reader back to the second device. Communication between the device and the smart card reader via a wireless communication link is slower than communication via a direct link. Communication of two or more commands and/or responses via the wireless communication link may be made more efficient by grouping the commands or responses together in groups.

Abstract: The invention relates to a plane structure, such as a wall, floor, ceiling or roof, comprising profiles (3A) extending mutually parallel in a first direction, elements (1) which can be coupled releasably to the profiles, wherein a profile extends on both sides of an element and wherein the elements are coupled to both adjacent profiles. The invention also relate to the elements and profiles for use in this structure, as well as to the method for building such a structure. An automatic positioning of the elements is created as a result of these measures; this then no longer depends on the skill of the builder. Owing to the releasability of the coupling the elements can simply be stacked on the profiles.

Abstract: For a defined cryptographic process including an original substitution table, split masked substitution tables are provided to resist cryptographic attacks. The split masked substitution tables are defined with reference to a set of random value data words and a mask value. An entry in the split masked substitution tables is defined by selecting bits from the corresponding entry in the original masked substitution table, as masked by the corresponding one of the set of random value data words and by selecting bits from the corresponding one of the set of random value data words as masked by the mask value. The split masked substitution tables are usable in a modified cryptographic process based on the defined cryptographic process to permit a masked output to be generated. The split masked substitution tables are refreshed by each entry in the tables being refreshed upon access during execution of the modified cryptographic process.

Patent CA-2616480-C (CA)
Title: Coated tablet with zero-order or near zero-order release kinetics
Inventor: GOLD THOMAS B
IPC: A61K9/20
Filed: 2006-07-21
Granted: 2014-09-09
Abstract: Tablets for the controlled release of an active ingredient in a zero-order or near zero-order fashion are provided. The tablet includes a core and a coating. The core includes at least one active pharmaceutical agent and a polyethylene oxide with a molecular weight of between about 1,000,000 and 10,000,000, preferably between about 4,000,000 and 8,000,000. The core material is optionally, but preferably, coated with a cellulosic material. The active pharmaceutical agent can be hydrophilic, hydrophobic, or amphiphilic.  When the active pharmaceutical agent is a hydrophilic agent, it is preferred that the coating is a relatively hydrophobic cellulose, such as ethylcellulose or propylcellulose. However, if the tablet is uncoated, it can provide a near-zero-order release rate rather than a zero-order release rate. When the active pharmaceutical agent is a hydrophobic or amphiphilic agent, the hydrophilic polymeric carrier is the same as in the first embodiment, the coating is a relatively more hydrophilic cellulose. The release rate for the active pharmaceutical agent can be controlled by adjusting the thickness of the coating, and, optionally, by adjusting the concentration of the polymeric excipients, as well as certain non-polymeric excipients which may optionally be present. An advantage of using relatively high molecular weight polyethylene oxide is that the release is pH independent, unlike where ionic polymers such as polyacrylic acids are used. Further, active pharmaceutical agents including functional groups that might react with such polymers can be used without an adverse reaction between the active agent and the polymer.
