Patent CA-2602753-C (CA)
Inventor: BARBER JOHN P
IPC: H05B6/02
Filed: 2006-03-20
Granted: 2013-01-15
Abstract: An improved induction heating apparatus is provided for attaching membrane roofs. A top membrane layer is attached to attachment disks that hold sheets of thermal insulation to the top of roof substrates. The heating apparatus emits a magnetic field that raises the temperature of the disks and a heat-activated adhesive on top of the disks which, after cooling, becomes adhered to the bottom surface of the top membrane layer. The disks in turn are attached via fasteners to the substrate portion of the roof structure. The apparatus includes a set of bottom guides that allow a user to find the attachment disks mechanically, without actually seeing those disks beneath the top membrane layer. A fine locator circuit is provided, using a magnetic field, and the apparatus allows a user to stand upright while operating the apparatus.

Title: High r-value window unit with vacuum ig unit and insulating frame
Inventor: THEIOS JASON
IPC: E06B3/00
Filed: 2006-12-11
Granted: 2010-10-19
Abstract: In certain example embodiments of this invention, a window unit may include a vacuum IG (VIG) unit as an inboard lite and a monolithic lite (e.g., with an optional low-E coating; thereon) as an outboard lite. A dead air space may separate the inboard and outboard lites. A highly insulated frame may be used to support the inner and outer lites. The VIG unit may be partially embedded or supported in the insulative frame, so that the insulating frame separates the VIG unit inboard lite from the outboard lite thereby reducing conductivity around the edges of the window unit so that R-value can be increased (and U-value decreased). In certain example embodiments, the total R-value of the window unit is at least about R-8, and more preferably at least about R-IO  (compared to the much lower R-values of conventional IG units).
Patent CA-2631787-C (CA)
Title: Fine bubble delivery for potable water, wastewater, and clean water treatment
Inventor: HINDE JOHN N
IPC: B29C48/11
Filed: 2006-11-28
Granted: 2014-07-29
Abstract: A flexible tubing (10) for fine bubble aeration is provided with an air passageway (20) defined in part by an upper portion (12) and a lower portion (14) . The tubing can be made of a uniform weighted material with more material in the lower portion than in the upper portion. This makes the tubing self-orienting, in that it will tend to orient itself with micro-slits (22) along the upper portion facing upward and the lower portion facing downward when submerged in a body of water. An automated, one-stage production line converts raw tubing material to a finished tubing product without the need for separate processing. A method of coiling the tubing places the micro-slits approximately 90~ away from the surface of a spool hub, thereby avoiding a longitudinal arch in the tubing and ultimately preventing roll-over and improper slit orientation after installation in a water body.

Title: Materiel d'alimentation pour recipient de separation solides- liquides
Inventor: SUTTON CLAY ROBERT
IPC: B01D21/24
Filed: 2009-07-14
Granted: 2012-03-27
Abstract: Méthode d'alimentation d'une charge, par exemple de mousse de bitume traitée par solvant paraffinique, à une cuve de séparation, par exemple une cuve de séparation de mousse de bitume (FSU). La charge est amenée d'un ou de plusieurs orifices d'admission latéraux qui peuvent être essentiellement conformes, et affleurants, aux parois de la cuve. Contrairement à certains systèmes d'alimentation classiques équipant des séparateurs par gravité, qui font appel à une plaque distributrice afin de répartir largement la charge dans une cuve, la charge est alimentée de manière à s'écouler vers le bas le long de la paroi intérieure de la cuve. Ce type d'alimentation se caractérise par un nombre de Richardson supérieur à 1,0. Une alimentation de ce type est particulièrement utile lorsque la charge comporte des particules d'une distribution de grosseurs bimodale qui doivent être séparées d'un flux de déversement. Un tel écoulement lent sert à atténuer le flux vers le haut des particules plus petites, par exemple les solides de minéraux, en les retenant sous les particules plus grosses, par exemple des agrégats d'asphalténes.
