Title: Electrostatically fiber planted steel sheet and production process therefor
Inventor: TATSUMI TERUYUKI
IPC: B05D1/14
Filed: 2000-08-08
Abstract: A fiber planted steel sheet obtained by forming only a fiber planting layer having excellent adhesion to a substrate made from a composition having special composition on the surface of a surface treated steel sheet as a substrate without forming a primer of a polyester synthetic resin containing an anticorrosive pigment and the like and electrostatically planting short fibers in the planting layer. Therefore, the electrostatically fiber planted steel sheet is produced by coating an aqueous adhesive composition for planting fibers comprising an emulsion resin having a glass transition temperature of -40 to 40 °C, aqueous coloring pigment dispersion, defoamer and pH modifier on the surface of the surface treated steel sheet to form a fiber planting layer having excellent adhesion to the steel sheet on the surface of the steel sheet and electrostatically planting short fibers while the surface of the planting layer retains adhesion.

Title: Liquid venting surgical system and cassette
Inventor: MORGAN MICHAEL D
IPC: A61M1/00
Filed: 2000-08-24
Abstract: A surgical system having a cassette with an aspirant collection chamber and an aspiration vent line that draws fluid from the aspirant collection chamber. The pressure within the collection chamber is maintained near ambient so that when the aspiration vent line is open, fluid flows from the collection chamber and into the aspiration line. Such a system does not require a second source of irrigation fluid, minimizes pressure surges into the irrigation fluid line and does not affect the fluidic performance of the aspiration system. In addition, various vent pressures can be achieved by varying the vertical position of the reservoir relative to the aspiration line.
Patent CA-2316848-A1 (CA)
Title: Improved video coding using adaptive coding of block parameters for coded/uncoded blocks
Inventor: LEE MING-CHIEH
IPC: H04N7/50
Filed: 1998-09-30
Abstract: Video coding efficiency for high motion scenes is improved by adaptively disabling a parameter indicating whether texture and motion data is coded for a macroblock. The COD parameter is disabled when the number of macroblocks with substantially all zero motion and texture data is less than a threshold number. This reduces the number of bits required to code an interframe video image in a video sequence with high motion and large changes from frame to frame. The coded block pattern for chrominance is also used to determine how to perform entropy coding for the coded block pattern for luminance.   In interframe blocks, if the chrominance blocks are coded, it is likely that the luminance blocks will be coded as well. The coded block pattern for chrominance, therefore, is used to select the appropriate entropy coding table for the coded block pattern for luminance.

Abstract: A stabilizer is used to immobilize a portion of the heart or other organ to facilitate a surgical procedure such as anastomosis. The stabilizer comprise s two, C-shaped, organ wall-contacting elements (12, 14), hinged together so that they can form a continuous loop. The hinge allows the C-shaped elements  to be separated so that, after surgery in which a tubular graft connected to  the organ extends through the loop, the stabilizer can be released from the graft. The C-shaped elements are connected to a stem which consists of two lockably articulating parts (30, 36), one of which is immediately connected to one of the C-shaped elements and aligned with the hinge axis. A spring-loade d sleeve (32), surrounding the last-mentioned part of the stem, has pins (76, 78) which engage recesses in the C-shaped parts to lock them in the closed condition, while allowing them to be opened quickly by manipulation of the sleeve. Removable, disposable pads (92) form the organ wall-contacting surfaces. An optional light carrier (102, 104) provides illumination, and ports (114) are provided in one of the C-shaped elements for suction and/or irrigation.

Patent CA-2337818-A1 (CA)
Inventor: KERRES JOCHEN
IPC: H01M8/1023
Filed: 1999-03-26
Abstract: The invention relates to a method for producing nitrated and optionally sulphonated and aminated and optionally sulphonated aryl main chain polymers , in addition to aryl main chain polymers thus modified. Aryl main chain polymers (e.g. (1)) are nitrated by dissolving them in expensive, toxic and environmentally damaging solvents. Aryl main chain polymers which are selectively and simultaneously nitrated and sulphonated were not previously known in literature. The inventive method makes it possible to produce low- cost nitrated (and optionally sulphonated (2)) or post-reduction aminated (a nd optionally sulphonated) aryl main chain polymers without any organic solvent s. Nitration (and optionally additional sulphonation) of the aryl main chain polymers occurs by dissolving them in concentrated sulphuric acid and by adding desired amounts of nitric acid at different temperatures and with different agitating times. The reaction can be carried out (a) as a two-step  process: nitration followed by isolation of the polymer, then optional sulphonation and (b) as a single-step process: simultaneous nitration and sulphonation (2). The nitrated (or additionally sulphonated) polymers can th en be reduced to form aminated (or additionally sulphonated) polymer. The polymers can be reacted with other polymers to form polymer blends. The polymers and polymer blends can be used as ion conducting membranes in elect ro membrane processes.

Abstract: A plug is disclosed that provides for electrically connecting an electronic device, such as a television, to a signal poet providing power, ground, audio/video, control and status-reporting signals to and from the device. The signal port is connected to terminals in a receptacle and the plug includes joining structure that can be inserted in or otherwise coupled to the receptacle to mechanically support the plug and the device. The joining structure is provided with retractable contacts to make the electrical connections with the terminals in the receptacle. The retractable contacts avoid damage when the joining structure is inserted into a receptacle that is fouled with debris because the contacts retract on contact with the debris rather than being bent or pushed out of place. The retractable contacts provide hemispherical, partially spherical, elliptical, flat, or other broad surface areas for electrical connection to the terminals, and the terminals may be provided with complementarily shaped and broad surface areas. The complementary shapes and broad surface areas allow for improved electrical connection even if the joining structure and receptacle are not perfectly aligned. The plug may also include an elongate projecting member terminating with first and second ends, with the first end being operatively connected to the joining structure so that the projecting elongate member extends from it and away from the receptacle. A pivot is provided so that the projecting member is articulable in a pivot plane. The projecting member also includes a connector located adjacent its second end for fastening to a housing/support structure for the electronic device.
