Granted: 2008-11-18
Abstract: An apparatus and method for bending and/or tempering glass substrate(s) are provided. The amount of near-IR radiation which reaches the glass (1) and (5 ) to be bent and/or tempered is limited (e.g., via filtering (12) or any other suitable technique). Thus, the IR radiation (7) (used for heating the glass) which reaches the glass (1) and (5) to be bent and/or tempered includes most ly mid-IR and/or farIR radiation (10), and not much near-IR. In such a manner, coating(s) (3) provided on the glass can be protected and kept at lower temperatures so as to be less likely to be damaged during the bending and/or tempering process. Heating efficiency can be improved. A ceramic (e.g., aluminosilicate) filter or baffle may be used in certain embodiments in orde r to reduce the amount of mid-IR and/or far-IR radiation reaching the glass to be tempered and/or bent.
Patent CA-2498993-C (CA)
Inventor: HOEVENAARS ANTHONY H
IPC: H02J3/01
Filed: 2005-03-01
Granted: 2012-03-20
Abstract: A harmonic mitigating device for connection between a power distribution system and the load uses a magnetic shunt to control the levels of magnetic coupling between different elements of the device while providing all windings on a single core. This allows for the reduction or elimination of the harmonic MMF induced in the line winding of the device, and as a result the reduction of harmonic currents flowing into the power supply system; and the reduction of the line winding inductance, which in turn reduces the voltage boost of the device under the no-load conditions, reduces the voltage drop at full load conditions and increases the stability of the drive. The invention serves to reduce ripple level in rectifier outputs and buffers transient overvoltages, and a single configuration works with any rectifier type, including SCR bridges.

Granted: 2007-04-10
Abstract: The present invention utilizes a containment tube (30) to facilitate production of a curly puff extrudate (20) and a blade (40) to nick the extrudate (16) as it exists a die. A gap is provided between the tube and an extruder die (12) to allow a blade (40) access to the extrudate (16) as it exits an orifice (14) in the die (12). The blade (40) accesses the extrudate (16) while it is in a viscous melt, before the extrudate (16) has cooled and hardened. The blade (40) nicks the extrudate (16), as opposed to completely cutting it, thereby allowing the extrudate (16) to remain connected throughout processing such as curling in the containment tube (30). The gap also allows steam to be vented form the extrudate (16) as it exits the orifice (14) in the die (12). The curly puff extrudate (20) separates when fried or baked.

Granted: 2012-05-08
Abstract: This invention relates to a novel method for economically processing vacuum residue from heavy crude oils by selectively processing the difficult and easy components in reactors whose design and operating conditions are optimized for the specific feed. The process utilizes an integrated solvent deasphalting (SDA)/ebullated-bed design wherein the heavy vacuum residue feedstock is initially sent to an SDA unit operated with C4/C5 solvent to achieve a high deasphalted oil (DAO) yield. The resulting SDA products, namely asphaltenes and DAO are separately treated in ebullated-bed reactor(s) systems whose design and operating conditions are optimized for a particular feedstock. The resulting net conversion, associated distillate yield and product qualities are greatly improved relative to treatment of the entire residue feedstock in a common ebullated~bed reactor, system.

Inventor: TAYLOR PHILIP LOUIS
IPC: C08K5/5397
Filed: 2004-07-21
Granted: 2013-01-08
Abstract: An autoxidisable architectural coating composition suitable for application to surfaces found in and around buildings at ambient temperatures and in natural daylight by unsophisticated users having no respiratory protection wherein surface autoxidation of the composition is promoted by a combination of low concentrations of metal ions (especially manganese or vanadium) and at least one photoinitiator. The composition avoids the need to use more than trace amounts cobalt ions which are rumoured to be carcinogenic yet achieves adequately fast rates of autoxidation. Preferably the use of cobalt is avoided altogether. The use of the low concentrations of the other metal ions reduces discolouration of the compositions often to levels below what is achieved using conventional cobalt promoters. It also improves gloss. Also a modification in which surface autoxidation is promoted by a combination of a photoinitiator and trace amounts of cobalt ions in the absence of other surface autoxidation promoting metal ions. Finally, a method for applying the autoxidisable coatings to surfaces under ambient temperatures in which they are subjected to natural daylight or similar low energy irradiation.
