re Silicone wax emulsion and method of manufacture By www.freepatentsonline.com Published On :: Tue, 14 Apr 2015 08:00:00 EDT Disclosed herein are silicone wax emulsions and methods of manufacturing the same. One method of manufacturing silicone wax emulsions as disclosed herein comprises charging alpha-olefins of C-18 or greater chain length to a heating and mixing vessel along with undecylenic acid and blocking the carboxylic acid of the undecylenic acid with a compound containing a trimethylsilyl group by adding the compound in sufficient quantity and heating as a melt until blocking is complete. While maintaining a melt temperature, a silicone polymer containing methyl hydrogen siloxy units is added, followed by a hydrosilation reaction catalyst to effect a hydrosilation reaction. This results in an acid functional silicone polymer. The acid functional silicone polymer is combined with an emulsifier, and the molten combination is added to a stirred solution of alkaline agent and water that has been heated to a temperature above the silicone wax melting point.

re Double-sided cutting inserts with anti-rotation features By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT A double-sided cutting insert may generally comprise a top surface, a bottom surface, at least one side surface interconnecting the top surface and the bottom surface and forming at least one cutting edge, a through hole extending between the top surface and bottom surface, wherein each of the top surface and bottom surface comprise at least one anti-rotation element. The cutting insert may comprise a single anti-rotation element on the top surface and a single anti-rotation element on the bottom surface. The anti-rotation element may be proximate to the through hole. A cutting tool using the cutting inserts, as well as methods of making and using the same are also described. Full Article
re Cutting insert, cutting body and clamping mechanism of a cutting tool assembly for chip removal By www.freepatentsonline.com Published On :: Tue, 19 May 2015 08:00:00 EDT A cutting insert (14) is formed with an insert aperture (32) opening out to insert top and bottom surfaces (14A, 14B) of the cutting insert (14). In a plan view of the insert top surface (14A), the cutting insert (14) and the insert aperture (32) both have oblong shapes which are elongated along a common insert longitudinal axis (AIL). The aperture (32) includes first and second side surfaces (32A1, 32A2) which each extend along the insert longitudinal axis (AIL), and aperture first and second end surfaces (32B1, 32B2) which each extend transverse relative to the insert longitudinal axis (AIL). At least one of the aperture first and second end surfaces (32B1, 32B2) is formed with a clamping lip (32C1, 32C2). Full Article
re Hybrid digital and channel microfluidic devices and methods of use thereof By www.freepatentsonline.com Published On :: Tue, 26 May 2015 08:00:00 EDT The present invention provides a hybrid digital and channel microfluidic device in the form of an integrated structure in which a droplet may be transported by a digital microfluidic array and transferred to a microfluidic channel. In one aspect of the invention, a hybrid device comprises a first substrate having a digital microfluidic array capable of transporting a droplet to a transfer location, and a second substrate having a microfluidic channel. The first and second substrates are affixed to form a hybrid device in which an opening in the microfluidic channel is positioned adjacent to the transfer location, so that a droplet transported to the transfer location contacts the channel opening and may enter the channel. The invention also provides methods of performing separations using a hybrid digital and channel microfluidic device and methods of assembling a hybrid digital microfluidic device. Full Article
