Patent CA-2203150-A1 (CA)
Inventor: HELLER NORBERT
IPC: B60J10/08
Filed: 1995-10-20
Abstract: A reinforcing channel-shaped carrier (22) for a sealing, trimming or guiding strip is made of metal and provided with slots of several different types. Slots (30) of a first type extend across the base (25) of the carrier and for short distances into the side walls (26, 28) and facilitate bending about an axis parallel to the base (25) and perpendicular to the length of the channel. Slots (32, 34) of a second type are positioned in the side walls (26, 28) and facilitate bending about an axis perpendicular to the plane of the base (25). The latter slots (32, 34) are of two different forms. Slots (32) of one form are shorter than those (34) of the other form. This increases the stiffness of the carrier. The carrier is produced by slitting a flat metal blank and then rolling it along stretch paths (42, 44) to cause it to be thinned-down and expanded lengthwise to convert the slits into slots. The carrier is advantageously used in a sealing, trimming or guiding strip in closed loop form ready for fitting to a vehicle door opening.

Patent CA-2222096-A1 (CA)
Title: A multi-metallic foil technology for minting medals and coins with two or three colors
Inventor: TEIXEIRA ANTONIO JOSE DO ROSAR
IPC: A44C21/00
Filed: 1997-02-10
Abstract: The invention deals with a technology for minting coins and medals. The technology is based on the utilization of metal blanks with similar diameters, one being very thin (hereafter named as the foil), joined together by mechanical means during the impartion of the surface details by the minting dies. The technology requires the design and manufacture of a special geometry in the edge of the thicker disk in order to make possible assembly of the metal blanks.        The proposed technology is based on a multi-stage manufacturing process consisting of three cold metal forming operations (preforming, rimming and coining) and one intermediate annealing treatment. The first metal forming operation ensures the preforming of the thicker disk blank, hereafter named as the disk.  The second metal forming stage is the rimming operation in which the preformed disk is bent along its diameter in order to generate a suitable profile for subsequent assembly with the foil. The third metal forming stage is a coining operation in which the metal blanks (disk and foil) are assembled together, by locking the foil into the rimmed edge of the disk, during the imprint of the surface details. The annealing treatment is to be performed before the coining operation. The goal is to restore the initial ductility of the disk prior to the final coining stage.

Filed: 1998-02-26
Abstract: A tool handle extension is permanently or semi-permanently attachable to a tool having a straight, elongate handle, such as a snow pusher, push broom, or similar tool. The extension enables the user to extend the reach of the tool for clearing large area having only limited access thereto, as in clearing snow from a roof area from an overlooking dormer window or the like. The extension is formed of standard, off the shelf components, with a cylindrical tube handle extension and crossmember forming a T configuration. Diagonal brace straps are provided between the ends of the crossmember and a lower point on the handle extension, for better lateral strength.      Additional features, such as hand grips, end caps for the tubular members, sleeves to accommodate differences in internal tube diameter and tool handle diameter, and anti-crush plugs inserted into the tubes at various attach points, may be incorporated.      Attachment of one tubular member to another is provided by forming an eye or passage through one of the members and inserting the other member therethrough. A larger diameter tube may be inserted through a smaller diameter tube, by expanding the eye of the smaller diameter as required. The present tool handle extension is particularly well adapted for compressive loads, as in pushing the tool, with the diagonal bracing providing strength for some lateral manipulation of the tool.
