Abstract: A snowmobile rear suspension assembly has a first and second suspension arms, a pair of slide rails pivotally connected to lower ends of the suspension arms and at least one shock absorber, a pair of extension arms pivotally connected to a rear portion of the pair of slide rails about a lateral axis and being pivotable between raised 5 and lowered positions about the lateral axis, a pair of rear idler wheels rotationally connected to a rear portion of the pair of extension arms, and at least one spring biasing the pair of extension arms toward the lowered position. At least a portion of at least one of the suspension arms is pivotable about a longitudinally extending axis relative to the pair of slide rails. A snowmobile having the rear suspension, a method 10 of replacing the slide rails of the rear suspension and a slide rails replacement kit are also disclosed.

Abstract: A snowmobile has a frame having a tunnel, a motor mounted to the frame, the motor having a motor shaft, at least one ski operatively connected to the frame and a continuously variable transmission. The continuously variable transmission has a driving pulley operatively connected to the motor shaft, a driven pulley, and a drive belt looped around the driving pulley and the driven pulley. The snowmobile also has a drive track operatively connected to the driven pulley, a flexible mechanical element operatively connecting the drive track to the driven pulley, the drive track rotating in a first direction during operation of the snowmobile, and at least one of the motor shaft. The driving pulley and the driven pulley rotate in a second direction opposite the first direction during operation of the snowmobile.

Abstract: A snowmobile has a front suspension and ski assembly having a right side and a left side. The right and left sides each have an upper arm, a lower arm and a spindle. A ski is connected to the lower portion of each spindle. At least one of the upper arms has a least one protrusion extending therefrom.

Abstract: A post-accident network probe and a method of using such a probe are disclosed. The probe is configured to be deployed in a confined environment (e.g. an underground mine), typically after an accident has occurred, in order to establish a connection with the wireless network, or a portion thereof, located therein. The probe generally allows the rescuers to determine the position of potentially trapped miners and can allow the rescuers to have access to environment-related information collected by the network, to get vital signs information, and/or to communicate with the trapped miners. The probe can be deployed using different access methods such as bore holes (existing or new), ventilation shafts, preventive installations of probes, etc. Notably, since the probe establishes a connection with the network, the location of the probe does not have to be exactly where the miners are located as long as the miners are tracked by the network.

Abstract: A rimless spectacle side arm mounting system, comprising a screw (2) installed approximately horizontally and approximately parallel to the “plane” of a lens (1), the thread of which is pointing to the outer edge of the lens (1), is free to cooperate with a nut (18) and is proud of the edge of the lens (1), a pair of spectacles comprising such a mounting system and a cord (20, 21) spectacle side arm, comprising a nut (18) in the form of an internally threaded dowel, one end of which is practically closed whilst still leaving room for the cord (20, 21) to pass through, the end of which on the side of the dowel (18) has a wider part to lock it in the dowel (18) whilst still leaving the dowel free to rotate.

Abstract: A multi-ply courier waybill comprises a plurality of data plies connected along et least one marginal edge to an underlying backing ply having a pressure sensitive adhesive applied to the undersurface thereof for attachment to a package to be shipped. The backing ply includes a plurality of die cut labels formed over a portion thereof spaced inwardly from the marginal edges of the backing ply, and the pressure sensitive adhesive is covered by a release liner. Removal of the release liner from the surface of the adhesive will result in removal of the die cut labels from the backing ply. At least some of the data plies and the die cut labels ere provided with common bar code indicia. The labels are applied to satellite packages so that only one waybill can accommodate a number of packages sent to the same addressee.

Abstract: A method of making an electrical connection includes forming in a pattern a plurality of electrically conductive elements on a first piece, forming another plurality of the electrically conductive elements on a second piece in the pattern, applying a layer of duroplastic resin capable of hardening and becoming conductive upon heating over the pattern of the elements of the first piece, heating the elements of the second piece, and placing the second piece against the resin with the heated electrically conductive elements of the second piece in juxtaposition with the elements of the first piece, thereby bonding the elements of the two pieces with the hardened and electrically conductive portions of the resins therebetween.

Abstract: A method of polymerizing a thermosetting resin such as an epoxy resin charged with silver particles in which shaped bodies of the resin are brought cold into contact with vapor of an organic liquid boiling at a temperature of above 100.degree. C. so that a condensate from this liquid forms on the bodies in temperature equilibrium so that the heat of vaporization is transferred upon such condensation rapidly to the bodies and the latter are polymerized rapidly under the constant temperature and pressure conditions.
