20120015159 | CYCLIC CARBAMATE COMPOUNDS USEFUL IN ENERGY-CURABLE COMPOSITIONS - Cyclic carbamate functional compounds, which are the reaction product of a cyclic carbamate having an acrylate functional group, such as N-(2-acryloyloxyethyl)oxazolidinone, with aliphatic amine compounds, said cyclic carbamate functional compounds being useful as oxygen scavengers in energy-curable compositions, such as inks, coatings and adhesives, that comprise (a) the cyclic carbamate functional compound, (b) reactive monomers and/or oligomers and, optionally, (c) a photoinitiator. | 01-19-2012 |
20150361284 | DIGITAL PRINTING INKS - The acrylate monomers of the present invention, particularly o-phenyl phenoxyethyl acrylate, provide very fast curing, hard and solvent resistant digital printing inks, and yet are also still surprisingly flexible. These properties make for a technically superior alternative to the widely accepted very hard monomer isobornyl acrylate. O-phenyl phenoxyethylacrylate also has the additional benefit of being free from the strong odor associated with isobornyl acrylate. | 12-17-2015 |

20100039309 | RELATING TO SCANNERS - The invention provides a security scanner that produces a radar profile of a clothed person or another object such as a bag carried by a person at a distance and does not require close proximity of the person or object to the scanner itself. The scanner includes a millimetre wave antenna system optimised for short-range active imaging and arranged to provide rapid high-resolution images of an object or person of interest and processing means for resolving the images so as to detect the presence of predetermined objects. The processing means preferably includes means for comparing contrasts in reflectivity in the scanned images with predetermined expected values from skin and light clothing. The processing means may also include means for detecting predetermined behavioural or physical traits such as the effect on gait on carried weighty objects or stiff structures strapped to the person from the images of a scanned object or person. The scanner may be incorporated within a turnstile access arrangement. | 02-18-2010 |

20150364754 | Silicene nanocomposite anode for lithium ion battery - A higher capacity silicene thin film structure with alternating layers of silicon nanoparticles which will result in an anode for lithium ion batteries. This nanocomposite structure will increase the specific capacity to 3500 mAh/g-1 versus 350 mAh/g-1 for state of the art lithium batteries. Charge/discharge cycles of 5000 with a maximum of 15% loss are also achievable. This is due to the silicene nanocomposites' capability to accommodate the mechanical expansion of the lithiated silicon species. Reliability defects such as copper cracking and delamination will be minimized using a barrier/adhesion metal layer. This will also reduce copper dendrite formation. Particle cracking and lithium plating will also be reduced by using the silicon based nanocomposite. The silicene nanocomposite can be fabricated using UHV-CVD methods minimizing transition to high rate production and recurring manufacturing product costs. | 12-17-2015 |

20100209265 | Gas Well Dewatering System - Power and control logic configurations for gas well dewatering systems are provided. In one example, a reservoir is configured to contain hydraulic, lubricating fluid. An electric motor is configured to receive fluid from the reservoir for lubrication and a hydraulic pump powered by the electric motor is configured to receive fluid from the reservoir and pump the fluid into a hydraulic circuit. A positive displacement oscillating pump is powered by the hydraulic pump and configured to pump fluid from the reservoir to an outlet from the well. The electric motor and hydraulic pump receive the same fluid from the reservoir for lubrication and to create pressure in the hydraulic circuit, respectively. A switching device is connected to the hydraulic circuit and is switchable between a first position wherein fluid pressure from the hydraulic pump causes the piston pump to move in a first direction and a second position wherein fluid pressure from the hydraulic pump causes the piston pump to move in a second direction. | 08-19-2010 |
