Patent CA-2573695-A1 (CA)
Inventor: BRINKMAN LARRY FRANK
IPC: C08J3/24
Filed: 2007-01-11
Abstract: Encapsulated base catalysts in the presence of Michael donors and acceptors result in compositions useful as adhesives, sealants, coatings, elastomers, films, and foams by providing unprecedented control over pot-life and cure rate in a two-part or multi-component system and allowing for use as a one-part composition. Encapsulated catalysts prevent premature reaction of the various reactants during storage and processing and yet, upon the rupture of the capsules by a pre-determined event such as the application of heat, pressure, or solvation, produce rapid cure. Use of encapsulated catalysts gives unprecedented control over pot-life and cure rate over compositions previously contemplated. As such the use of encapsulated catalysts also results in the potential for one-part Michael addition compositions previously not known. The use of encapsulated catalysts also allows for faster green strength development by providing for a very rapid cure upon rupture of the capsules.

Abstract: Over human history, a tremendous amount of time, labour and money has been spent on removing and disposing horse manure. Given the population growth in rural municipalities close to major cities and the resultant increase in horse-ownership, a safe and responsible means of manure management has become critical. The Enviro Muck Bucket can help address this dilemma. Combining the advantages of a manure cart, with the benefits of a manure spreader, it can provide a means of effective manure management. It employs a manually-operated muck bucket that is suspended over a chute drum housing a toothed shredding wheel assembly that distributes broken-up manure (fresh or dry) over a chosen area and is intended for use by the smaller-operation horse owner when mucking out stalls and disposing the manure.

Title: Dark, flat element having low heat conductivity, reduced density and low solar absorption
Inventor: HUGO GERD
IPC: C09D7/41
Filed: 2005-12-02
Abstract: The invention relates to a dark, flat element, preferably a plastic, lacquer coating or fiber material, having reduced density, low heat conductivity and low solar absorption. The flat element has a relatively high reflection in the near infrared range of the electromagnetic spectrum in order to reduce heating by sunlight in the near infrared area despite dark tinting in the visible range. Low density and low heat conductivity are obtained inter alia by inserting light filling materials into the flat element. Said flat element can be used in places where surfaces are dark tinted for aesthetic or technical reasons but should not heat up in sunlight and should give off little heat when touched by hand or by other parts of the body. Other areas of application include surfaces which should have a heat insulating effect in addition to the above-mentioned characteristics.

Abstract: The present invention relates to an environmental, health and fire safety system to be used in concert with small scale and portable technologies for the production of transesterified fatty acid alkyl esters for use as biodiesel or other applications. Methanol or other alcohol vapors generated through the transesterification of fatty acids are explosive and limit the application of small scale biodiesel technologies, as they offer significant health, explosion or fire risks. Liquid solvent or fuel spills can cause significant environmental liabilities. The invention allows for the users of all biodiesel fabrication technologies to eliminate solvent emanation and contain liquid spills. A primary enclosure (1), which may be retractable and portable by way of a trailer or skids, is mounted over the transesterification or biodiesel fabrication device (2) prevents possible toxic fumes from dispersing into the surrounding environment. A ventilation system (4) actively forces the possible toxic vapours through a venting system to a location outside the enclosure through a vent (6).  Electrical panel controls (3), if applicable, are mounted preferably outside of the enclosure to meet with electrical and safety regulations. Moreover, an air flow control mechanism is attached to the system to stop power to the transesterification devices if the enclosure and ventilation system are not in place and activated. A sump reservoir is added to the system for the purpose of collecting, through gravity, liquid spills that make arise from the malfunctioning of the biodiesel manufacturing. External reservoirs which hold feedstocks and by products are connected to the biodiesel fabrication devise for through hoses or pipes which penetrate the enclosure through wall breaches (8).

Abstract: A turbine control system for a variable speed electrical generator in a wind turbine mounted atop a support tower (202). The wind turbine converts wind energy into a driving torque applied to the generator (230). The control system includes a turbine support tower position sensor (204) and may also include other tower acceleration and velocity sensors. A wind flow estimator (208) uses the measured motion, generator rotation rate (216) and blade pitch angle (212) to predict wind flow over the swep area of the turbine's rotor, and the tower motion . The predicted wind flow and motion is used in the turbine control system to properly adjust its operating point, to tune the controller, to control the rotor rotation rate, and to damp tower oscillations.
