Patent CA-2220456-A1 (CA)
Title: Flue gas scrubbing and waste heat recovery system
Inventor: HINKE THOMAS V
IPC: B01D53/60
Filed: 1996-05-29
Abstract: A system and method for the reduction of NOx in a flue gas are disclosed. A P4 in water liquid/liquid emulsion is injected into the flue gas to induce phosphorus-accelerated oxidation of the NO in the flue gas. NO2 and phosphorus oxides are subsequently removed from the flue gas stream at a location sufficiently downstream of the injection site that the oxidation of NO in the flue gas is substantially complete prior to the removal of NO2. This significantly improves the NOx recovery rate of the present system and method over those of the prior art. The system can be retrofitted to the waste gas stream of any stationary combustion source regardless of the fuel burned. The system is advantageously used in connection with a wet scrubber for the removal of NO2 and other water soluble flue gas components. Injection of the emulsion results in the creation of ozone by means of the controlled oxidation of white phosphorus. The ozone reacts with nitrogen oxide (NO), which generally accounts for 90 % of flue gas NOx, to produce nitrogen dioxide (NO2). The reaction products (NO2 and the P4O10) can be removed from the flue gas together with SO2 and particulates in the wet scrubber wherein they are efficiently transferred from the gaseous phase to the buffered scrubbing liquid. In the scrubber, the temperature gradient is preferably set through the dew point, so that it recovers both latent as well as sensible heat energy from the flue gas which energy can be sold to commercial or residential consumers to recover at least a part of the capital costs (purchase and operation) associated with the system.

IPC: A01N37/18
Filed: 1998-01-23
Abstract: An agent for contact lenses, comprising chloroacetamide.  According to the present invention, chloroacetamide, which is the bacteriocidal component to be contained, is scarcely adsorbed not only to hard contact lenses and gas-permeable hard contact lenses, but also to soft contact lenses, and even if adsorbed, moreover, chloroacetamide is quickly released and is not accumulated on the contact lens to a greater extent.  The inventive agent containing, in addition to chloroacetamide, sodium lauryl sulfate shows more superior bacteriocidal effect and cleaning effect.  Therefore, the present invention provides an agent for contact lenses having superior bacteriocidal effect and cleaning effect, which can be used safely and with ease for various contact lenses inclusive of soft contact lenses.

Title: Glass for information recording medium substrate and glass substrate
Inventor: ZOU XUELU
IPC: C03C3/062
Filed: 1997-09-04
Abstract: SiO2 -Al2 O3 -RO (where R is a bivalent metal) glass which has a high specific elasticity larger than 36 × 10 6 Nm/kg or a high Young's Modulus larger than 110 GPa and has a high transition temperature (high heat-resistance) higher than 700 °C. A glass substrate which has an excellent surface smoothness (surface roughness Ra < 9.ANG.) and a high strength can be provided by using this glass. Since the glass has the excellent heat-resistance, the glass substrate is not deformed during the heat treatment which is necessary for the improvement of the characteristics of a magnetic film. Since the glass substrate has the excellent surface smoothness, the reduction of the floating height of a magnetic head (i.e. the increase of the recording density) can be achieved. Since the glass substrate has a large specific elasticity and a large strength, the thickness of a magnetic disc can be reduced and, further, the breakage of the magnetic disc can be avoided.

Title: Absorbent wound dressings
Inventor: ADDISON DEBORAH
IPC: A61L15/60
Filed: 1998-04-30
Abstract: The invention provides a wound dressing (1) comprising a wound contacting sheet (4) laminated to one side of an absorbent layer (3) of water-swellable absorbent material such as a polyurethane. A liquid water-impermeable backing layer (2) is laminated to the other side of the absorbent layer (3).  The wound contacting sheet is provided with one or more slits (5) therein. Expansion of the absorbent layer (3) due to absorption of wound exudate causes the slits (5) in the wound contacting sheet (4) to expand, thereby allowing passage of high flow rates of wound exudate. If the flow of exudate falls, then the slits close, thereby avoiding excessive drying of the wound surface.
