Title: Heat treatment of carbon materials
Inventor: LYNUM STEINAR
IPC: C01B31/04
Filed: 1996-07-05
Abstract: The invention concerns a method for heat treatment of carbon materials and especially carbon black in a plasma process for increased order in the nanostructure, i.e. an increased degree of graphitization in the carbon black particles. The process consists in an upgrading of commercial carbon black qualities and non-graphitic carbon materials. The heat treatment is conducted in a plasma zone where the residence time and power supplied are controlled in order to ensure that the carbon material does not sublimate. Thus the carbon which is supplied to the plasma zone is prevented from being transformed and reformed into a new product.
Patent CA-2227127-A1 (CA)
Inventor: HEMPHILL ROBERT C
IPC: B44D3/12
Filed: 1998-03-30
Abstract: A support for an artist's tool such as a paintbrush or pen is provided. The apparatus suspends the paintbrush or tool such that the bristles or nib remain partially immersed in liquid medium, thus preventing it from drying out during a work session. The apparatus can be adjusted to fit various size tools and for variable depths of the container or liquid. In use the device prevents the bristles from being deformed from prolonged contact with the bottom or sides of the container.      SUMMARY      Artists using quick drying mediums are faced with the problem of preventing the brush or pen from drying out during pauses in work. The usual practice of leaving a brush soaking in a container, resting on its bristles, inevitably deforms the tip rendering it useless for fine work. With pens the finger-grip often becomes coated in the medium, making the risk of stained fingers smudging the work a probability. The object of this invention is to provide a means of suspending an artist's paintbrush or tool in a container of fluid so that the brush or tool may remain saturated. Additionaly in the case of a paintbrush the bristles are prevented from contacting the sides or bottom of the container avoiding the resulting deformation of the tip.      BRIEF DESCRIPTION OF THE DRAWINGS     Figure 1.) is a perspective view of the preferred embodiment of the device Figure 2.) is a side view of the device in use Figure 3.) is a plan view of multi-size support disc
Patent CA-2227487-A1 (CA)
Inventor: SCHMIDT ROBERT LEWIS
IPC: H04N19/593
Filed: 1998-01-20
Abstract: A  predictive  video  coder  performs  gradient prediction based on previous blocks of image data. For  a  new  block  of  image  data,  the  prediction determines  a  horizontal  gradient  and  a  vertical gradient from a block diagonally above the new block (vertically  above  a  previous  horizontally  adjacent block).    Based  on  these  gradients,  the  encoder predicts image information based on image information of either the horizontally adjacent block or a block vertically adjacent to the new block.   The encoder determines a residual that is transmitted in an output bitstream.     The  decoder  performs  the  identical gradient  prediction  and  predicts  image  information without need for overhead information.   The decoder computes the actual information based on the predicted information and the residual from the bitstream.

Title: Optical microprobes and methods for spectral analysis of materials
Inventor: DEBARYSHE GREGORY
IPC: G01N21/47
Filed: 1996-08-01
Abstract: An optical probe collects light emanating from a specimen that selectively and preferentially represents a localized volume element within the sample, with illumination intensity and collection efficacy both dropping off away from the localized volume element to limit the integrated contribution from outside the element. For example, the optics provide high peak illumination and high collection efficiency which both overlap in volume elements of a limited size corresponding to a structure or process of the specimen. The resulting collected signal comprising one or more spectral segments is highly correlated with optical characteristics, such as absorbance, scattering or fluorescence characteristics of material in the small volume elements. A processor may apply a previously-derived vector or matrix transform to the collected responses to produce an output. The collected spectra or other responses have high signal strength and represent small or otherwise inaccessible or masked optical effects present in the sample, so that they are readily correlated to conditions of interest.

Title: Single pass ink jet printer
Inventor: MOYNIHAN EDWARD R
IPC: H01L41/24
Filed: 1998-02-05
Abstract: In the particular embodiments described in the specification, a single pass ink jet printer includes a plurality of ink jet modules (54) arranged in adjacent rows extending across the width of the surface of an object which is moved with respect to the printer. The modules (54) are mounted on and joined to a manifold (84) which is mounted in a support frame (82). Ink is supplied to the manifold through an opening (98) in the frame and the manifold distributes the ink to corresponding openings (66) in the ink jet modules where it is directed to arrays of ink pressure chambers and to an outlet which communicates with a corresponding return passage (102) in the manifold leading back to the ink supply. As a result, ink can be circulated continuously through all of the ink jet modules, thereby maintaining pigment in suspension in a pigmented ink.  An ink supply is removably connected to the printhead through quick-disconnect couplings and, to prevent contamination of the ink in the printhead, filters are provided in the ink supply and at the inlet to the printhead. A further filter (86), designed to trap only those particles which would block the orifices in the orifice plate, is positioned between the ink jet modules (54) and the orifice plate (90). In one embodiment twelve ink jet modules (54) are arranged to provide approximately 275 dot per inch (108 dot per cm.) resolution across a 5.6 inch (14.2 cm.) image width and in another embodiment forty-eight ink jet modules (54) are arranged to provide 600 dot per inch (236 dot per cm.) resolution across a 10.-1/4 inch (26 cm.) image width.

Abstract: Beam spread transformers are required for chip-fibre couplings and must be polarisation-independent, show low losses and be economically produced. In a beam spread transformer (1) with an integrated structure having several buffer layers (5) mutually separated by conductive layers (6), an uncladded rib waveguide (7, 8) with a tapering area (9) is arranged on the top buffer layer (5). A section (11) over which the rib (8) extends is located between the interface (2) with the fibre and the tapering area (9). The waveguide layer (7) is completely removed from this section and the exposed buffer layer (5) is reduced to a width w2 which exceeds the width w1 of the continuous rib (8) in a symmetrical manner. The thus obtained additional rib (12) makes it possible for the coupling to be polarisation-independent and to be optimised with the increased heights (d1, d2, d3) thanks to the buffer layers (5).
