20090197975 | COMPOSITIONS FORMULATED FOR SOLVENT-REGULATED DRUG RELEASE - This application relates to a composition comprising a mixture of different organic solvents formulated for controlled drug release. The release profile of the drug can be regulated by adjusting the compositional ratios of the solvents. In one embodiment of the invention a first solvent is water-soluble and a second solvent is water-insoluble. The first and second solvents are miscible and together form a solution containing the drug. The hydrophobicity of the composition can be adjusted by altering the relative amount of the second solvent. The composition also includes a solid lipid dissolved in the drug-containing solution. In aqueous environments the lipid may precipitate to form a thin membrane in an outer surface portion of the composition, thereby further regulating the release of the drug. The membrane is preferably renewable. That is, as the outermost portion of the lipid is biodegraded at a target location in vivo, additional outer portions of the lipid precipitate to renew the thin membrane. The composition may be formulated, for example, as a suspension, nanoparticle, microparticle, paste or thin film coating. In one particular embodiment, the composition may be applied to an implantable medical device, such as a cardiovascular stent. | 08-06-2009 |
20100018865 | ELECTROLYTE SOLUTION AND METHOD FOR ELECTROLYTIC CO-DEPOSITION OF THIN FILM CALCIUM PHOSPHATE AND DRUG COMPOSITES - Disclosed herein are electrolyte solutions and methods for electrolytic co-deposition of calcium phosphate and drug composites. The electrolyte solution may be formed by mixing solutions comprising calcium and phosphate precursors together to form an electrolyte solution. The electrolyte solution can have a water content less than 30 weight percent. The electrolyte solution may comprise a water-soluble non-aqueous solvent. A therapeutic agent, such as water-insoluble drug, is also present in the solution. The electrolyte solution thus formed may be used to co-deposit a calcium phosphate coating and the therapeutic agent on a substrate. One method includes the steps of immersing the substrate in the electrolyte solution and applying an electrical potential to the substrate to thereby cause (i) the calcium and phosphate precursors to electrochemically react with hydroxyl groups on the surface of the substrate and deposit the calcium phosphate coating thereon; and (ii) the therapeutic agent to electrophoretically migrate to the substrate and become co-deposited thereon together with the calcium phosphate coating. The method thus provides a convenient and easily controllable means for depositing thin film calcium phosphate and drug composites on substrates such as implantable medical devices. | 01-28-2010 |

20110101951 | Zero-Voltage-Switching Self-Driven Full-Bridge Voltage Regulator - non-isolated full bridge (FB) converters have self-driven synchronous rectifier (SR) MOSFETs in the current doubler rectifier (CDR). The gate terminals of the SR MOSFETs are connected to the bridge leg midpoints of the FB converter. The primary side of the FB converter shares the same ground of the secondary side, which provides the gate drive path for the SRs.

High gate drive voltages can be used to reduce the on-resistance of SRs and the conduction loss. In this way, no additional gate driver circuitry is needed for the SRs compared to the conventional external drive circuitry for SRs.

20110113848 | METHODS FOR REDUCING RIDGE BUCKLES AND ANNEALING STICKERS IN COLD ROLLED STRIP AND RIDGE-FLATTENING SKIN PASS MILL - A method for flattening steel strip by cold rolling the strip by passing it through at least two cold rolling mill stands each having work rolls. A first of the mill stands has work rolls having local rigidity K significantly different from a second mill stand, wherein the local rigidity K is calculated in Kgf/mm/mm accordance with an equation. Also a six high mill for flattening steel strip has an entry side where the strip enters the mill and an exit side where the strip exits the mill. The mill comprises a pair of driven backup rolls disposed on the entry side of the mill, a pair of horizontal support rolls disposed on the exit side of the mill and a pair of small diameter work rolls, the work rolls having an entry side face and an exit side face. The work rolls are disposed between the pair of backup rolls and the pair of support rolls. The entry side face of the work rolls is in engagement with the backup rolls during operation and the exit side face of the work rolls is in engagement with the support rolls during operation. | 05-19-2011 |

20080289494 | DECOMPOSITION OF NATURAL GAS OR METHANE USING COLD ARC DISCHARGE - The invention provides methods and apparatus for a cold arc discharge used to decompose natural gas or methane into its gaseous constituents and carbon in the form of solid particles. The gaseous constituents obtained are mainly hydrogen and acetylene and they are produced in admixture with unreacted natural gas or methane. | 11-27-2008 |
20090038933 | Decomposition of Natural Gas or Methane Using Cold Arc Discharge - A cold arc discharge is used to decompose natural gas or methane into its gaseous constituents and carbon in the form of solid particles. The gaseous constituents obtained are mainly hydrogen and acetylene and they are produced in admixture with unreacted natural gas or methane. The cold arc discharge is generated by a pulsating high voltage discharge imparted through a capacitor to a high voltage electrode or a plurality of high voltage electrodes or through a high voltage electrode to a plurality of capacitor—connected electrodes placed in a reaction zone. The apparatus for performing this process may have a tubular reactor with a cylindrical ground electrode in the middle and a cylindrical outer wall through which the high voltage electrode or electrodes extend into the reaction zone. The apparatus may also have a cylindrical shaft in the middle made of dielectric material in which a plurality of electrodes are embedded, this shaft being surrounded by a high voltage tubular electrode. Natural gas or methane is passed through the reaction zone where it is subjected to the cold arc discharge or discharges and the resulting products flow out of the reactor and solid carbon particles are separated from the remaining gases that are then analysed. | 02-12-2009 |
20110239542 | APPARATUS AND METHOD FOR EFFECTING PLASMA-BASED REACTIONS - There is provided a reactor system comprising a plasma generator and a reaction vessel. The plasma generator is configured for effecting a plasma discharge into a reaction zone to produce a plasma plume. The reaction vessel defines the reaction zone. The reaction vessel includes a reactant flow inlet configured for flowing and discharging gaseous reactant flow into the reaction zone, and a stabilizing gaseous flow inlet configured for introducing and effecting vortical flow of a stabilizing gaseous fluid into the reaction vessel. The vortical flow of the stabilizing gaseous fluid effects a spatial disposition of the plasma plume such that at least a fraction of the gaseous reactant flow intersects the plasma plume. | 10-06-2011 |

20100095493 | LOCKING MECHANISM - A locking apparatus is disclosed. The locking apparatus includes a female receptor for locking with a male member. The male member locks with the female receptor by moving the male member with respect to the female receptor in a first direction. The male member is unlocked from the female receptor by moving the male member an additional distance further in the first direction. The female receptor includes resilient arms to hold and release the male member and spring arms that contact the resilient arms. | 04-22-2010 |

20110007630 | Bandwidth provisioning tools for internet service providers - An accurate bandwidth provisioning tool for Internet Service Providers, for both Voice over IP and data traffic, which is able to predict the demand for network resources based on the network traffic characteristics and the number of subscribers after taking into account subscriber growth and other relevant factors. To predict the demand, the tool uses a Gaussian model for Voice traffic, and a Gamma model, or alternatively, a dimensioning formula, for data traffic. The tool also discloses a method of planning Cable television network capacity when converting analog channels to digital channels. | 01-13-2011 |
