Title: Roller sealing apparatus for forming a weather seal between a vehicle and a loading dock or the like
Inventor: HOFFMAN DAVID J
IPC: E04D13/18
Filed: 1999-02-19
Abstract: A sealing apparatus (14) for forming a weather seal between a vehicle (V) and a loading dock (4) is provided. In some embodiments, the apparatus includes a roller seal (14) rotatably mounted to a support (22) for rotation about an axis (30). The roller seal (14) is movable in at least a vertical direction from a first position in the path of a vehicle (V) entering the parking area, to a second position wherein the roller seal (14) is disposed adjacent the top of the vehicle (V). Preferably, a curtain (60) is suspended distally of the roller seal (14) such that, when the roller seal is in the second position, the curtain (60) forms a first seal with the top of the vehicle (V) and the roller seal (14) forms a second seal with the top of the vehicle (V). The curtain (60) is semi-rigid and, in some instances, defines a ramping surface (175) to facilitate movement of the roller seal (14) over the leading edge of a vehicle (V) approaching the loading dock (4).

Inventor: JIA NANCY Y
IPC: G03G15/16
Filed: 2000-11-08
Abstract: An intermediate transfer belt with a mechanically and electrically invisible seam formed by joining two ends of the belt at a seam. Two regions of the belt are thus formed, a seam region at and around the seam and a far region away from the seam. An overcoat is then placed over the seamed substrate such that an outer surface of the overcoat forms a toner-bearing surface. The seam region has good electrical property correspondence (as explained in the patent) with the far region and a lateral resistivity greater than 108 ohms/square. The joining of the belt can occur along a kerf.

Title: Channeled glass article and method therefor
Inventor: ALLEN STEPHEN R
IPC: C03B9/00
Filed: 1999-02-08
Abstract: The method herein shapes a thin glass article (10), as well as a thin glass interface (20, 22) between two laminated sheets (16, 18) as they seal together to form the glass article (10). This process changes the shape of the article (10) and modifies the internal interface (20, 22) at the juncture where the glass sheets (16, 18) meet to make the channels (12). As a result, the juncture is very thin and very little or no slope. The process uses the mechanical motion of a plunger combined with plunger vacuum and internal gas pressure to make these changes. The technique reduces the contact area between glass layers (16, 18). A reduced contact area can reduce the optical interference caused by the joining of two layers of glass (16, 18). The technique also makes the front surface of each channel (12) thinner. The glass thinness also allows for thinner products with substantially reduced light distortion at the juncture.

Patent CA-2327843-A1 (CA)
Inventor: HACK JEFF
IPC: G06T3/00
Filed: 2000-12-07
Abstract: Systems and methods for registering hemispheric images obtained using a fisheye lens for panoramic viewing, relating to spatial alignment and colour balancing of complement half-side images derived from the hemispheric images. The systems and methods for spatial alignment determine the displacement of the digitized recorded images using a single translation and rotation model of distortion, which further evaluates the centre of projection, and the extent of translation and rotation. The system and method for colour balancing iteratively increase (or decrease) the values of pixels near the edge (discontinuity) between the two half-sides of an image, each time taking into consideration the average difference of pixel colour across a smaller strip of the edge near the pixel. This invention removes the colour differential but does not remove any detail underlying the features of the image.

Inventor: HANSEN W PETER
IPC: G01N15/00
Filed: 2000-02-18
Abstract: The high numerical aperture flow cytometer of the present invention includes a flow cell and a laser input. The laser input emits a beam of light that is oriented substantially orthoganilly to the flow of blood cells through the flow cell such that laser light impinges upon the blood cells as they pass through the flow cell. A portion of the beam from the laser input that impinges upon the blood cells in the flow cell is scattered at a substantially right angle to the beam of laser input ("right angle scatter"). A second portion of the beam from the laser input that impinges upon the cells in the flow cell is scattered at a much lower angle than 90~. This scatter is termed "low angle forward scatter light" and has an angle of from about 2~ to about 5~ from the orientation of the original beam from laser input. A right angle scatter light detector is oriented to receive the previously mentioned right angle scatter light. A low angle forward scatter light detector is oriented to capture the previously mentioned low angled forward scatter light oriented at about 2~ to about 5~ beam from laser input.

Title: Street sweeper
Inventor: KRAWETZ JEFFREY J
IPC: E01H1/05
Filed: 2001-04-17
Abstract: A street sweeper comprises a vehicle mounted on ground wheels for running along a roadway with a two part pivotal boom arrangement carried on the vehicle and pivotal upwardly, downwardly, forwardly and rearwardly together with outwardly to respective sides. At the end of the boom is mounted a brush member which is suspended on the boom from the top of the housing with ground wheels at the front and rear of the housing so that the housing can rollover the ground.  The housing carries a transverse cylindrical brush member rotating about an axis transverse to the housing and thus at right angles to the length of the boom.  The housing floats by slots on a pin at the end of the boom so that its height is controlled by the ground wheels but its position and the orientation of the rotary axis of the brush is controlled by the position of the pin at the end of the boom. The brush member can thus be moved readily to required locations for a brushing action to sweep materials forwardly or rearwardly onto a roadway for collection by a conventional street sweeper.
