Patent CA-2077293-A1 (CA)
Inventor: LOCE ROBERT P
IPC: G03G15/01
Filed: 1992-09-01
Abstract: A pulsed imaging, facet tracked, Raster Output Scanner utilizes pulse width modulation in conjunction with spatial filtering to form three exposure levels at the surface of a charged photoreceptor medium, one of the levels associated with a specific color.  This type of scanner with a nominal video rendering experiences a color line growth in the process direction.  The line growth problem is caused by a coherent optical effect. The resultant output print has bolded color lines in the process direction. Several techniques are set forth to compensate for this line growth.  In a preferred technique, the video data stream is modified by locating or positioning video pulses representing white information at the start of an associated pixel time period.  When the color pixel is imaged, it will therefore, always abut an adjoining white pulse and will be inhibited from spreading into the adjacent pixel period.  Other techniques rely upon inversion of white pulses, or separation of white pulses into two signals, each segment moved to the beginning and the end of the associated pixel period.  According to another technique, the input data stream is buffered and pixel groups examined to identify neighboring white and color signals. These signals are then either narrowed or in the case of a sequence of color signals, the lead and trail edge of the color signals are trimmed.

Title: Sewing machine assemblies
Inventor: ASKIN MICHAEL
IPC: D05B23/00
Filed: 1991-03-06
Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides that a sewing machine is used for sewing the adjacent edges of a flat felt web which is folded to bring the edges together.  The web moves past the sewing machine, and the sewing machine is mounted so as to reciprocate in a forward stroke in the direction of the web during the stitching, and to move rearwards back to an initial position to effect the next stitch.  The drive mechanism of the sewing machine is such that from the commencement of the forward stroke the machine is accelerated up to the speed of the web the needle penetrates the web and effects the stitch, the needle is removed from the web, and then is decelerated to zero before completing the backstroke.  The invention also relates to an optical sensing mechanism for examining the presence of stitches.

Patent CA-2080963-A1 (CA)
Title: Faceted container
Inventor: AYLWARD THOMAS J
IPC: B65D1/26
Filed: 1992-10-20
Abstract: ABSTRACT An injection molded container having a generally circular bottom panel, a side wall extending from the bottom panel, and lid receiving lip structure extending about the projecting wall end defining a container end opening opposite the bottom panel.  The side wall extends about a central axis through the bottom panel and end opening.  The side wall comprises a continuous outer wall face intersecting a plane extending normal to the axis along a substantially circularly curved line and an inner wall surface defined by a series of facets.  The inner wall face intersects the plane along a line having a substantially polygonal shape composed of straight line segments corresponding to respective facets with each straight line segment extending tangent to a second subs-tantially circular line within the first circular line. The side wall defines a series of spaced load supporting ribs each defined between a facet and the outer face. Each rib has a maximal thickness equal to the radial distance between the first and second circularly curved lines proceeding from the center of the panel.  The side wall has a series of thin walled segments each having a minimal thickness along a radial line extending medially between adjacent ends of adjacent straight line segments. The maximal thickness rib has sufficient cross sectional area to assure injection molding material flow from the bottom panel area to the lip structure and sufficient column strength to enable mechanical capping of the con-tainer.  The thin walled segments are narrow and just thick enough to effectively resist radially inward defor-mation when the container wall is supported internally during printing.

Abstract: GARMENT HANGER AND TOY COMBINATION            ABSTRACT OF THE DISCLOSURE           A garment hanger and toy combination comprises a head and body disposed along a longitudinal axis and limbs extending  outwardly  from  the  body  transversely  of  the axis.   Support   means   is   provided   for hanging   the combination  and  is  extendible  outwardly  from  a  recess within a top portion of the head when the combination is to be used as a garment hanger,  and is retractable into the recess when the combination is to be used as a toy. Movement of the support means is along the axis and is limited to axial movement only, with negligible rotational movement. Preferably, the support means is subjected to an outwardly directed resilient force,  and the support means can  be  latched  with  a  latch  structure  against  the outwardly  directed  force  to  hold  the  support  means retracted. The latch structure can be released by direct application of a force to a lower portion of the body, or alternatively  can  be  released  by  bending  the  limb sufficiently to release the latch.

Patent CA-2089655-A1 (CA)
Title: A method and a system for producing block bodies from loose material such as sphagnum
Inventor: ELLEGAARD OYVIND
IPC: A01G9/10
Filed: 1991-09-03
Abstract: In the production of growth blocks of sphagnum there are considerable operational problems with the required compacting of the loose sphagnum, as both compaction worms and pistons may easily get stuck. Instead, the invention provides for the use of a suction technique, whereby the loose sphagnum is sucked into a perforated pipe in a suction chamber, whereby a marked compaction of the material is achievable without any use of mechanical devices. The compacted block material may be surrounded by a decomposable paper casing, which is laid in successively as a lining hose of air permeable paper. The compacted material can be delivered as a compact string by successive projection movements of the suction chamber for being cut into blocks, and the suction chamber can be temporarily opened for free return movements into its initial position.

Title: Message Routing for Sonet Telecommunications Maintenance Network
Inventor: MAZZOLA ANTHONY J
IPC: H04Q3/66
Filed: 1993-03-29
Abstract: A routing method, performed by intelligent network elements of a data communications network having SONET applications, for selecting a path from a source network element to a next network element.  Each network element has access to a database containing the addresses of its neighboring network elements and their types.  To select a next network element, a routing network element first attempts to find a neighboring network element that is the same as the destination network element.  If it has no such neighbor, the routing network element then attempts to find a neighbor that is in the same area as the destination, or failing such a neighbor, in the same routing domain.  Optionally, the routing network element looks for a neighbor that has been selectively provisioned as a next network element.  At each step, candidate network elements are eliminated by using data about their type and application to determine if they call for duplicate paths.
