Patent CA-2224065-C (CA)
Inventor: JONES ROGER H JR
IPC: C04B41/65
Filed: 1996-06-03
Granted: 2002-08-06
Abstract: Cured cement matrices are exposed to high pressure dense-phase orsupercritical CO2 which enters the matrix through passages therein to neutralize the natural alkalinity of the cement so that alkali-intolerant materials can be incorporated in the cement. The CO2 converts calcium hydroxide in the cement to calcium carbonate and water, and the high pressure of the dense-phase or supercritical CO2 forms rounded, closely packed and aligned crystals with few or no visible pores or capillaries to enhance the homogeneity and strength of the cured cement and its bonding with, for example, uncoated reinforcing glass fibers. The supercritical CO2 can be used to transport other organic or inorganic materials, including pulverized metal, in solution or suspension into the interior of the cement matrix to alter its chemical and/or physicalcharacteristics.

Title: Engine mounting for belt driven machine
Inventor: THIER RICHARD DAVID
IPC: A01D34/42
Filed: 1998-04-28
Granted: 2001-12-11
Abstract: An engine mounting structure is provided for use with a turf care machine such as a greens mower. Single cylinder engines, such as are used on greens mowers and similar turf care cutting machines, generate significant vibration. Greens mowers and which are used for finish cutting lose cut quality and precision with excessive vibration. To reduce vibration, an improved mounting structure includes resilient mounts to support the rear portion of the engine on the machine frame. To avoid belt misalignment between the engine drive pulley and the driven pulley powering the cutting reel, which can occur when resiliently mounting an engine, the forward portion of the engine is rigidly secured to the machine frame.

Title: Suppression of coherent rayleigh noise in bidirectional communication systems
Inventor: BOIVIN LUC
IPC: H04B10/29
Filed: 1998-09-17
Granted: 2003-04-15
Abstract: Low-noise, bidirectional communications in a fiber optic cable is achieved by coupling a first end of the cable to a spectrally-sliced optical power source. A second end of the cable is coupled to an optical detector having a detector bandwidth, such that the bandwidth of the optical power source is greater than the detector bandwidth. When the bandwidth of the optical power source is large compared to the bandwidth of the detector, the beat frequencies resulting from coherent Rayleigh noise fall outside the bandwidth of the detector and are not detected.

Title: Apparatus for separating particles from a fluid flow and a valve for introducing bled fluid to a mainstream fluid
Inventor: DYSON JAMES
IPC: A47L9/16
Filed: 1997-07-03
Granted: 2004-11-16
Abstract: A bleed valve (30) for introducing bled fluid to a mainstream fluid flowing through apparatus (16) across which a pressure differential occurs, characterised in that the bleed valve (30) is adapted to open so as to bleed fluid into the mainstream fluid when the pressure differential across the apparatus (16) falls below a predetermined value. Th is arrangement is particularly appropriate to vacuum cleaners incorporating cyclonic dust-separating apparatus in that the bleed valve is more reliably operated in response to a reduction in airflow. This ensures efficient functioning of the cyclonic dust-separating apparatus and reduces the risk of overheating of the motor.

Title: Sequential application method for treating plants with exogenous chemicals
Inventor: FENG PAUL C C
IPC: C05G5/23
Filed: 1997-08-14
Granted: 2009-01-13
Abstract: A novel method is provided wherein plants are first treated with an exogenous chemical (e.g., glyphosate herbicide) and then sequentially treated with a liquid accession agent which provides improved biological (e.g., herbicidal) effectiveness such that plants are controlled with lower rates of the applied exogenous chemical (e.g., glyphosate herbicide). Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that can be exhibited when the accession agent is added to a herbicide in a tank mix or simple coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain organosilicone-based and fluorocarbon-based surfactants.

Abstract: The apparatus includes a flow control conduit (2) connectable with an output portion of the heart, prefer-ably a bypassed portion of the aorta, and includes a means of feeding heart fluid (R/O), for example blood or cardioplegia into the heart. The flow control device (1) includes in communication a variable resistance pressure control means (4) which is variably biased to a closed position to maintain on the bypassed heart region a pre-determined level of pressure, to facilitate the creation of back pressure during filling of the bypassed heart re-gion or a beat or pumping phase of the heart, and when the heart fluid pressure increases to reach a predeter-mined threshold, the pressure control means facilitates a release of fluid from the conduit, thus facilitating expul-sion of potential emboli from the bypassed heart region, and enabling "cycling" of the heart whilst in a bypassed condition, prior to the bypassed region being taken off bypass. The invention includes preferred and alterna-tive embodiments of variable resistance pressure control means including a hollow deformable bladder (16) bi-ased by a compressible control fluid externally of said bladder.

Abstract: Butane-utilizing bacteria are used to degrade hydrocarbon pollutants such as trichloroethene (TCE). In situ or ex situ techniques may be used to reduce or eliminate hydrocarbon pollutants from liquid, gas and solid sources. In a preferred embodiment, TCE concentrations in various aqueous environments are reduced by contacting a contaminated wat er source with butane-utilizing bacteria in the presence of oxygen to degrade the TCE by cometabolism or direct metabolism. Suitable butane-utilizing bacteria include Pseudomonas, Variovorax, Nocardia, Chryseobacterium, Comamonas, Acidovorax, Rhodococcus, Aureobacterium, Micrococcus, Aeromonas, Stenotrophomonas, Sphingobacterium, Shewanella, Phyllobacterium, Clavibacter, Alcaligenes, Gordona, Corynebacterium and Cytophaga. The butane-utilizing bacteria have relatively low TCE toxicity in comparison with conventional methane-utilizing bacteria, and demonstrate an improved ability to degrade TCE.

Abstract: A work platform (48) is supported by a sleeve (46) which is movable along a tower (40) having a plurality of vertically equally spaced rungs (45). The raising system (50) of the invention comprises two hydraulic rams (52), pivotably attached to the sleeve (46) and equipped with corresponding hooks (58) at the extremity of their piston rods (52a). The rams (52) are activate d simultaneously in up and down movement but in alternate directions, bearing in a hooking engagement in turn on the rungs (45) of the tower (40) to pull the  sleeve (46) upwards along the tower (40). When a rung (45) is in the path of  a hook (58) in the upward movement, the latter pivots backwards to clear the rung (45) and is pivoted back by means of springs (66). The lowering operati on of the sleeve (46) is done similarly to the raising operation, but there is provided latch levers (82) that an operator must unlatch to allow springs (8 6) to pivot the hooks (58) in a rung clearing position during the retraction of  the corresponding ram's piston rod (52a), so that the hook (58) will clear t he rungs (45).
