Title: Polyfluorosulfonamido amides useful as intermediates in the synthesis of polyfluorosulfonamido amines
Inventor: SHTAROV ALEXANDER BORISOVICH
IPC: C07C311/09
Filed: 2010-07-01
Abstract: Current methods for making polyfluorosulfonamido amines, which involve the use of a diamine reactant, provide low yields and produce an undesirable fluorine containing bis-sulfonamide by-product representing an economic loss. The bis-sul-fonamide by-product is particularly undesirable because it shares very similar physical properties with the desired monoamine product thus making isolation of the desired polyfluorosulfonamido amine product difficult and costly. Furthermore, instead of the efficient incorporation of fluorine to make the desired polyfluorosulfonamido amine product, the bis-sulfonamide by-product con-stitutes a substantial loss of costly fluorinated starting material. The bis-sulfonamide by-product also constitutes an undesirable impurity that can worsen surfactancy, repellency, or other performance characteristics of the desired polyfluorosulfonamido amine product. The present invention provides a method of making a polyfluorosulfonamido amine without the production of a bis-sul-fonamide by-product by reacting a polyfluoroalkylsulfonic compound with a monoamino amide rather than with a diamine reac-tant as in previously known methods.

Patent CA-2775188-A1 (CA)
Inventor: LIMAYE AMIT UDAY
IPC: A61M5/32
Filed: 2012-04-20
Abstract: Disclosed is a safety pen needle assembly which includes a hub, a needle fixed to a transverse wall of the hub, and a shield formed to at least partially telescope over the hub. An outer ablumenal surface of the hub and an inner lumenal surface of the shield are formed with cooperating thread elements to permit relative rotation between the hub and the shield. In an initial state, the shield and the hub are configured with a rotation-resistance arrangement which inhibits relative rotation between the hub and the shield. The rotation-resistance arrangement is surmountable to allow relative rotation between the hub and the shield with an at least threshold amount of torque being applied.  Advantageously, a safety pen needle assembly can be provided having a shield threaded onto a hub with the assembly being mountable with the needle being in a shielded state.  This minimizes the possibility of needle stick during mounting of the safety pen needle assembly.

Title: Formulation of drugs and vaccines in the form of percutaneous injectable needles
Inventor: GARCIA DE CASTRO ANDREWS ARCADIO
IPC: A61K9/00
Filed: 2010-10-08
Abstract: The invention relates to percutaneous administration of drugs and vaccines in form of solid penetrating needles, "injectable needles", comprising a polymeric matrix resulting from the polymerization of a polymerizable paste or mixture. The injectable needles are hard enough to penetrate the skin and can be administered percutaneously by simple pusher or injector delivery devices. The manufacturing procedure of the injectable needles allows for the incorporation of the drug as preformulated stable microparticles and incorporation of modifying agents to modulate stiffness, solubility and drug release. Drugs formulated in these injectable needles offer a safe, simple and effective alternative to conventional percutaneous drug delivery systems based on hypodermic needles and syringes that require refrigerated storage and reconstitution prior to administration.

Inventor: DAVIS RICHARD
IPC: E21B10/30
Filed: 2011-03-31
Abstract: A method for hardening a portion of the outer surface of a downhole tool body includes friction stirring the vulnerable surface of the tool. Such friction stirring generally includes rotating a friction stir weld tool in contact with the surface until a portion of the tool penetrates the tool. The friction stir weld tool is then translated (while rotating) across a predetermined region of the surface thereby creating a friction stir zone. The friction stir zone is generally considerably harder, and therefore more wear resistant, than the parent material that makes up the tool body. The resulting downhole tool includes at least one surface with a hard friction stir zone.
