Patent CA-2261600-C (CA)
Inventor: ALLGULIN TORKEL
IPC: B01D53/78
Filed: 1998-05-22
Granted: 2004-03-02
Abstract: A method for removing gaseous elementary mercury from a gas that can be permitted to contain sulphur dioxide. The gas is treated in a washing tower with washing liquid that circulates in a closed system and that contains 0.01-300 mmol/l mercury (II) ions and at least twice this amount of chloride ions. The elementary mercury present in the gas is oxidised and solid mercury (I) chloride is formed. A part of said formed solid mercury (I) chloride is passed to a reaction unit for oxidation to mercury (II) chloride. Chlorine intended for said oxidation and liquid intended for taking-up mercury (II) ions formed by said oxidation process is caused to pass up through a reaction zone in the bottom part of the reaction unit and said zone is kept substantially full of solid mercury (I) chloride. The quantity of chlorine is adapted so that said chlorine will be essentially consumed during its passage up through the reaction zone. The liquid and its content of formed mercury (II) ions is united and mixed with the washing liquid present above said reaction zone and thereafter the so united washing liquid is passed with its increased mercury (II) content to the closed circulating system to be recycled to said washing tower as a compensation for the mercury (II) ions consumed for the oxidation of elementary mercury.An appara tus for effecting the method has a washing tower (11) and a reaction unit (26) with a smaller cross section than the tower (11). The reaction unit (26) is connected to the bottom of the tower (11) and has conduits and means for maintaining a closed circuit system of washing liquid from a liquid outlet (41) in the lower part of the tower (11) to a liquid inlet (40) in the upper part of the tower (11). The lower part (42) of the washing tower (11) below the level of the liquid outlet (41) has a tapering cross section for adaptation to the reaction unit (26).</SDOA B>

Title: Controlling aip print uniformity by adjusting row electrode area and shape
Inventor: YOUNG MICHAEL YU-TAK
IPC: B41J2/045
Filed: 1999-05-13
Granted: 2003-03-11
Abstract: An acoustic ink print head includes an array of individual emitters. Each of the emitters have a corresponding transducer with a lower electrode, a separate layer of a piezo-electric material located on the lower electrode, and a separate upper electrode provided on the upper surface of the piezo-electric layer. The upper and lower electrodes are connected to a source of conventionally modulated RF power. A dielectric layer is deposited on top of this structure and lenses are etched into the top of the dielectric layer. The lenses focus energy generated by the transducer to a region of the upper surface of a body of liquid located above the transducer. Tree lenses concentrate sound waves from the transducers thereby disturbing the surface and causing droplets to be emitted. The print head is formed as an array of individual emitters. The upper electrodes of the individual emitter array have varying surface areas dependent upon their location within a row of electrodes and their output efficiencies. The upper electrodes are altered in order to provide a uniform end-to-end print output.

Title: Method and apparatus for monitoring haemodynamic function
Inventor: DUNLOP COLIN
IPC: A61B8/06
Filed: 1998-05-13
Granted: 2009-07-07
Abstract: The present invention relates to a method and apparatus for monitoring haemodynamic function in animals and humans during anaesthesia and surgery. During anaesthesia and surgery the subject's haemodynamic, respiratory, neuromuscular and neurological functions are monitored as indicators of the condition of the health of the subject. Commonly, variations in blood pressure are used to imply corresponding variations in cardiac ouput, i.e. good blood pressure equals good cardiac output. The present invention utilises a device to monitor changes of blood flow in peripheral blood vessels of the subject as an indicator of cardiac output. This is believed to provide a much more accurate indicator.

Title: Turbine blade to disk retention device
Inventor: GEKHT EUGENE
IPC: F01D5/02
Filed: 1999-11-22
Granted: 2008-08-19
Abstract: The invention provides a turbine blade retention device installed in an axially extending gap between the blade root bottom and the slot floor. The retention device has two parts: a blade root retention clip and a spacer bar.  The clip has an elongated web of a selected web thickness and width less than the width of the slot floor. The clip includes a forward and a rearward transverse flange extending radially outwardly and extending laterally from forward and rearward ends of the web. The flanges serve to engage the forward and rearward faces of the rotor hub disk respectively, and to engage forward and rearward faces of an associated blade root. The height of at least one flange is less than the gap depth to permit conventional sliding installation of the blade root. The spacer bar is installed in the gap between the clip and slot floor to hold the clip radially outward in engagement with the forward and rearward faces of the blade root. The spacer bar has a thickness that, together with the clip web thickness, substantially equals the gap depth. Preferably, the spacer bar extends axially through the gap and has forward and rearward bent over tabs for engaging the forward and rearward faces of the rotor disk hub.

Title: A method of performing an impregnating treatment on a resin-containing wood substrate
Inventor: HENRIKSEN OLE
IPC: B27K3/34
Filed: 1999-11-04
Granted: 2010-11-02
Abstract: The impregnating or extracting treatments of resin-containing wood substrate using a resin-soluble supercritical fluid as delivering or extractive solvent medium problems due to exudation of resin from the wood substrate at pressure release necessary before the termination of the treatment are avoided or reduced by displacing at least partially the supercritical fluid by a fluid of relatively low solubility in the resin before pressure release down to atmospheric pressure is terminated. Thereby the total process time can be substantially reduced.
