Abstract: A solar air heating module provides heated air to a ventilation system. The solar air heating module includes a collector for heating and drawing in outside air and a housing. The collector includes an absorber plate for absorbing incident sunlight and includes a plurality of perforations therethrough. The perforations are distributed across the absorber plate for allowing passage of air into the collector. The collector also includes a collector tray mounted behind the absorber plate. The collector tray includes an output for allowing the passage of air out of the collector. The collector tray is spaced from the absorber plate to define a cavity therebetween in which air can to flow towards the output. The housing is mounted to the collector tray and forms a plenum therewith for receiving air from the output. The plenum is at a lower pressure than that of the outside air. The plenum is connected to the ventilation system. A plurality of modules may be combined to form a system.

Patent CA-2699885-A1 (CA)
Inventor: CUEVAS BRIAN J
IPC: A61M16/04
Filed: 2008-09-15
Abstract: There is provided a balloon cuffed tracheostomy tube (160) with a balloon (175) designed so as to enhance the tube's anchorability without sealing the tracheal stoma (210). The tracheostomy tube device includes a conventional curved hollow tube.  The distal (165) end of the tube is adapted for insertion through a tracheal stoma and into the tracheal lumen (200) of a patient's throat. The device further includes an inflatable balloon enveloping a portion of the tube. The balloon has a distal portion (180) substantially centered about and attached to the distal end portion of the tube, and a proximal portion (185) attached to the bend region of the tube and positioned substantially off-center relative to the proximal portion of the tube and about the bend region below the proximal plane of the device. Upon inflation, this configuration provides for expansion of the balloon around the distal end portion of the tube and the proximal end portion of the tube below the proximal plane of the device to seal the trachea below the tracheal stoma and to avoid sealing the trachea above the tracheal stoma. This configuration of the balloon should allow secretions to exit the stoma so that they do not accumulate and become a possible source of ventilator acquired pneumonia.

Patent CA-2721573-A1 (CA)
Title: Solvent assisted oil recovery
Inventor: HUGHES TREVOR
IPC: C09K8/524
Filed: 2009-04-23
Abstract: The recovery of oil from a reservoir is assisted by injecting a diluent into the reservoir formation to reduce the viscosity of the crude oil.    This diluent is a mixture of a material which is an asphaltene precipitant, especially supercritical carbon dioxide, and a more polar material which comprises at least one aliphatic compound which includes at least one of a cycloaliphatic ring, an olefinic unsaturation, an ester or ether group. The inclusion of such an aliphatic compound which is more polar than the asphaltene precipitant reduces asphaltene precipitation and can enhance the efficiency of oil recovery when the precipitant is by supercritical carbon dioxide.
