Patent CA-2288323-A1 (CA)
Inventor: KLARNER RICHARD GENE
IPC: F28F9/013
Filed: 1999-11-02
Abstract: A support plate for retaining tube array spacing within a heat exchanger tube and shell structure. The support plate having a plurality of individual tube receiving apertures formed therein. Each apertures has at least three inwardly protruding members and bights are formed therebetween when the tube associated therewith is lodged in place to establish secondary fluid flow through the support plate. The inwardly protruding members terminate in flat lands that restrain but do not all contact the outer surface of the respective tube. These flat lands minimize fretting wear and eliminate potential gouging of the outer wall of the tube. The plate wall forming each aperture has an hourglass configuration which, inter alia, reduces pressure drop, turbulence and local deposition of magnetite and other particulates on the support plates.

Abstract: A pickup reel for a harvesting platform including a reel support structure with a reel shaft rotatably supported thereon. A plurality of radially extending arms are mounted to the reel shaft and a plurality of transverse rockshafts are mounted to the radially extending arms and are axially offset and parallel to the reel shaft and span the width of the platform. Radial fingers are mounted on each rockshaft. A cam is mounted to the support structure adjacent one or both ends of the rockshafts and defines an endless cam path about the reel shaft. A crank arm attached to each rockshaft carries a cam follower that engages the cam path for following along the path. The cam path is configured to cause the crank arms, and thus the rockshafts, to rotate about the respective rockshaft axis to vary the attitude of the fingers relative to the ground as the cam followers move along the cam path. The cam is segmented, having two or more cam segments joined together to form the endless cam path. The cam segments are joined together by removable fasteners to enable one segment to be removed and replaced to either vary the cam path or to replace a worn cam segment.

Title: Method and apparatus for charging boreholes with explosives
Inventor: PERLID HANS
IPC: F42D1/10
Filed: 1998-05-12
Abstract: A method and a device for charging boreholes (11) with explosives. One end of a charging hose (3) is introduced to a substantially predetermined distance from the bottom of the borehole. Subsequently, a pumpable explosive is pumped through the charging hose at a controlled rate and substantially simultaneously with the pumping of the explosive the charging hose is withdrawn from the borehole at a controlled rate.  The explosive is caused to flow out from a nozzle (13), arranged on said end of the charging hose (3), in the form of a hollow cone (18) and at high pressure, so that the outflowing explosive is given increased viscosity and by virtue of the high outflow rate cohesively adheres to the entire cylinder-shaped wall portion (19) of the borehole (11), upon which the explosive impinges in connection with said outflowing. With the aid of a centring device (14), the nozzle (13) is centred in the borehole (11).

Title: Method for production of hydroxylamine sulfate in the conventional process for the synthesis of caprolactam
Inventor: VELLOSO ANTONIO AUGUSTO M
IPC: C07D201/06
Filed: 1999-12-22
Abstract: An improvement in the conventional process for the production of caprolactam. The process involves: (a) reacting air with ammonia gas in an ammonia conversion zone to produce nitric oxide; (b) oxidizing a portion of the nitric oxide to nitrogen dioxide to produce an NO x-rich process gas stream; (c) reacting the NO x-rich stream with ammonium carbonate in a nitrating zone to produce ammonium nitrite; (d) reducing the ammonium nitrite to hydroxylamine diammonium sulfate; (e) hydrolyzing the hydroxylamine diammonium sulfate to hydroxylamine sulfate; (f) oximating the hydroxylamine sulfate with cyclohexanone to produce cyclohexanone oxime; and (g) converting the cyclohexanone oxime to caprolactam.   The process is improved by adding supplemental oxygen downstream of the ammonia conversion zone to increase the quantity and rate of formation of nitrogen dioxide in the NO x-rich process gas stream.

IPC: G06T13/40
Filed: 1998-06-24
Abstract: A system and method for defining and employing behaviours for articulated chains in computer animations. At least one control, such as a shape control or a resolution plane control, is defined for the articulated chain and is employed as a constraint by the animation engine when animating the chain with inverse kinematics. Each control comprises two or more keys, each key comprising a couple of an effector direction vector and an associated constraint. In the case of shape control keys, the associated constraints comprise a list of preferred limb orientations and in the case of resolution plane control keys, the associated constraints comprise a preferred orientation for the resolution plane. For any given goal, selected control keys are interpolated with appropriate weightings to obtain a resulting constraint to be employed by the animation engine.

Title: Digital film grain reduction
Inventor: SHEKTER JONATHAN MARTIN
IPC: G06V10/30
Filed: 2000-05-23
Abstract: Reduction of film grain in digitized photographs and motion picture footage is an important problem with applications in such areas as special effects compositing, archival restoration, and fixed-bandwidth lossy compression. Current techniques widely used in practice (such as median filtering) are shown, both theoretically and practically, to be significantly suboptimal for this problem, especially for colour images. Previous work on the subject of film grain removal in particular and image noise reduction in general is extensively examined.  Bayesian estimation is then proposed as a unifying model for noise reduction, and several classical techniques are rederived in a Bayesian framework. The dimensionality reduction techniques needed to make Bayesian estimation practical are discussed, the failure of certain classical colour noise reduc-tion algorithms is explained, and the form of an ideal grain reduction technique is postulated. Finally, an algorithm based on these ideas is proposed and tested. This algorithm out-performs earlier techniques by exploiting correlations between the colour channels of an image.
