Patent CA-2583853-A1 (CA)
Inventor: LAHAIE DENIS
IPC: B23K31/12
Filed: 2007-04-04
Abstract: The described embodiments relate generally to methods and apparatus for use in determining solderability of an electrical component. One particular aspect relates to apparatus comprising a vacuum chamber, a load sensor, a platform and a control module. The load sensor has a contact portion disposed within the vacuum chamber and the platform is disposed in relation to the contact portion and has a component mounting surface and a mounting member for mounting an electrical component to the component mounting surface. The control module causes relative movement between the platform and the load sensor so that a contact surface of the electrical component is brought into close proximity with the contact portion. When the contact portion has solder thereon and the solder is brought into contact with the contact surface, the load sensor measures force arising from wetting of the solder to the contact surface. The force generated under contact changes over time, depending on the degree of solderability of the electrical component. Thus, measurement of the wetting forces over time provides an indication of the solderability of the electrical component.

Title: System and methods for wall and ceiling fastening
Inventor: BROWN GREGORY A M
IPC: F16B21/00
Filed: 2006-06-23
Abstract: A system (100, 600, 700) for fastening objects to a wall or ceiling (120) comprises a rear, wall-anchor section (105, 607, 705) with a bore, and a front, pivotable section (110, 602, 604, 720), rigidly abutted together with no gap, aligned by a projection (135), and connected by a "living" hinge, strap, flap, lanyard or other type of connector (115). The pivotable section has a sharpened tip (112, 630, 635, 725) for penetrating the wall while the fastener is forced into the wall by a hammer or other driving tool or device, or manually by hand. The two sections of the fastener have a tapered, elliptical cross-section (111) which both prevents rotation of the fastener and locally reduces load-responsive pressure in the wallboard. To install, the axes of the wall-anchor and pivotable sections of the fastener are first aligned. The fastener is forced into the wall one of the above means. Then a pin (140) is manually inserted into the bore of the wall-anchor section. When the pin meets the projection the pivotable section is forced to rotate about the hinge. A locking tooth (139) secures the pin by interfering with either threads or notches in the pin. Alternatively, the pin forces past the projection and wedges between the projection and the bore of the wall-anchor section.
