Title: Method for extracting anthocyanin derivatives from a plant source
Inventor: SAVARD SYLVAIN
IPC: C07D311/62
Filed: 2012-12-14
Abstract: The present document describes a method for extracting anthocyanin derivatives from a plant source. The method comprises the step of separating a homogenized extract of plant source in a polar acidified solvent for obtaining a residual solid, and a filtrate mixed with the acidified polar solvent. The separation includes a coarse filtration done by centrifugation of the plant source extract, by a filtration with a first filter having a pore size of about 100µm, and a fine filtration is done using a second filter having a pore size of about 10µm. Then, the filtrate mixed with the acidified polar solvent is evaporated for substantially separating the acidified polar solvent from the filtrate to obtain a semi-solid extract of anthocyanin derivatives.

Abstract: An image recording device having a projected viewfinder is described that projects individual, or multiple sets of synchronized framing beams onto a target image that are coaxially aligned with the field of view of the camera. The set of framing beams is projected onto the target image beyond the scope of the field of view being recorded by the image recording device but still within the field of vision of the operator of the device. In this way, the operator of the image recording device will be able to clearly see the framing beams identifying the limits of the recorded areas, while not having any portion of the field of view of the image recording device obscured by the framing beams themselves.

Filed: 2015-01-19
Abstract: This device designed to attach to standard heater duct used today. Twelve inch inlet pipe. A box shape with air baffle, curved front to allow for better air flow and ease of placement. It has 10 inch wheels attached to the front and a removable handle bolted under the box.  The overall height when placed under the engine is 14 inches on a level surface. The width is 14 inches and length of the box is 36 inches. A welded aluminum construction makes it 45 lbs total weight. We measured the road height of bumpers to determine the best size allowing standard trucks on the road today. This also allows for engine warm up of heavy equipment engines in service but blocks might lift the heater closer to the engine on bigger equipment. This device will allow for a standard heating attachment that will save time and prevent accidents from misplaced heater ducts.

Abstract: A method of recovering oil and producing steam for injection into an injection well to assist in the recovery of oil from an oil bearing formation. An oil-water mixture is recovered from an oil bearing formation. Oil is separated from the mixture to produce an oil product and produced water where the produced water includes suspended solids and dissolved solids. The produced water is directed to a treatment system and treated by removing suspended solids and dissolved solids to produce treated water. The treated water is directed to a forced circulation steam generator and pumped therethrough. The water passing through the generator is heated to produce at least one water-steam mixture. The steam produced in the generator is mixed to 30% or less quality steam. The flow of treated water to the generator is maintained such that the flow of water to the generator is at least five times greater than the steam produced by the generator. The steam produced is collected and directed into the injection well.

Abstract: Multi-speed transmission for electric vehicles (EVs) can reduce the size of the electric motor and provide an appropriate balance between efficiency and dynamic performance.  Currently used multi-speed transmissions for EVs were initially designed for internal combustion engine (ICE) vehicles. Since ICEs cannot operate below certain speeds and their speed control during gear changes is not an easy task, the presence of clutches or torque convertors is inevitable for start-ups, idle running and gear changing. This, however, is not the case for EVs as electric motors are speed controllable in a wide range of operating speeds. Accordingly, transmissions without clutches or torque converters are established for EVs.
