Abstract: A portable testing device is provided to verify the operational status, as either functional or non-functional, of lights and brake equipment on a vehicle. The mobile testing device 10 for testing a lighting and brake system of a vehicle, comprising means for coupling the mobile testing device 10 to said vehicle; a plurality of light testing devices to test the operation of the vehicle lights; and a brake testing system for initiating the vehicle's braking system and determination on the operational condition of said braking system. The mobile testing device 10 further comprising a battery for supplying power to said vehicle light during testing.

Abstract: An extruder apparatus has an extruder flow channel 10 for an extruder head having a pair of flow passages 40, 50 and a flow dam 12 interposed between the flow passages and a flow splitter 14 that locally increases or locally decreases the flow area of the first flow passage 40 relative to the second flow passage 50. The preferred flow channel 10 adjusts the mass balance of the flows 6, 7 between passages 40, 50 automatically.

Abstract: The present invention relates to a rubber article having a surface construction designed for abrasion resistance wherein the surface comprises a series of rubber layers parallel to each other and in a density of from at least 200 layers per 25.4 millimeters as measured along the surface area of the article and in a direction perpendicular to each layer.

Abstract: A method and apparatus for detecting anomalous cords in reinforced composites uses means to deform and/or vibrate the composite and detect the vibration signature of the composite. Broken or frayed reinforcement cords in a reinforced composite cause changes in the vibration signature of the composite, and the apparatus used in the method of the invention employs a low damping material which is used in proximal contact to all the reinforcement cords in the reinforced composite, and one or more sensors to detect said changes. The apparatus may also include a computer for collating data, analyzing data, and providing a signal when an anomalous cord is recognized.

Abstract: A liquid cooling system for a snowmobile or other relatively small vehicle having a heat exchange element with front and rear surfaces and air passages extending therebetween, a plurality of air guides for providing a flow of air to the front surface of the heat exchanger and a duct for directing air flow from the rear surface of the heat exchanger upwardly through a portion of the vehicle hood. Preferably the heat exchange element is tipped to increase the flow of air therethrough during idling and at slow speeds.

Abstract: An energy absorber comprises an elastomeric member in a substantially trapezoidal configuration, a piston connected to the apex of the trapezoid, and piston retaining and mounting supports. The elastomer absorbs energy by virtue of its inclined buckling columns forming the sides of the trapezoid while the piston is forced to move in a substantially horizontal plane by the piston retaining and mounting supports. The energy absorber, when applied to vehicle applications, provides a bumper mount that accepts frontal and lateral force impact and lends itself to bumper jacking and towing forces.
