Abstract: A method for shaking vehicles comprises driving them over a series of appropriately spaced-apart, mutually parallel bars to vigorously shake the wheels, undercarriage, and body to free them of dirt, gravel and debris. An apparatus may have bars with the appropriate spacing. A track may include a frame and the spaced-apart bars may form part of the frame. The track may be large enough to accommodate all the wheels of a vehicle at once. Alternatively, smaller tracks may be flexibly connected end-to-end to form a shaker that will receive right and left hand wheels of the vehicle on respective rows. The shaker may be deployed onto a bed of aggregate that is sufficiently coarse to allow the fallen dirt to sift or be washed through the bed of aggregate. The aggregate may also assist in holding the shaker in place and may provide ramps at the ends of the shaker.

Abstract: Deicing of an external mirror (10) on a vehicle is effected by applying a sudden deformation force to the mirror. Sandwiched between the mirror (10) and a mounting surface (12) is a structure that includes a ribbon conductor (14), portions of which overlap each other in such a way that current through the conductor passes through these portions in opposite directions. A capacitor (32) is discharged through the conductor (14), generating a magnetic field that results in mutual repulsion between the overlapping portions. The mounting surface resists this repulsion force, which is instead transferred to the mirror (10), causing momentary distortion, and dislodgment of ice on the mirror surface. The same technique is also applicable to deicing of windows.

Abstract: Methods and apparatus for removing swarf from machined components are described, in which a component is mounted on support means and the latter is vibrated in a manner to cause the component to be accelerated alternately in one direction and then the other, for a period of time. The acceleration is such as to cause the component to momentarily lift off the support means during at least part of each of the vibrations so as to bounce repetitively on the support means. The latter includes fingers adapted to engage non-critical regions of the components to reduce damage to machined surfaces or distortion of the machined component during vibration. A fluid flushing may precede and/or follow the vibration step.

Abstract: An anode rough cleaning system has three rough cleaning stations and an overhead conveyor to move spent anode assemblies sequentially through the three stations. The overhead conveyor supports each spent anode assembly in a hanging vertical position with the carbon butt suspended therebeneath. A first station is a vibrating station which vibrates the carbon butt to separate the bath material from the carbon butt. The vibrating station has an inclined surface and a vibrating surface. The overhead conveyor is arranged over the inclined and vibrating surfaces to drag the carbon butt up the inclined surface, causing the spent anode assembly to rotate from the vertical position to an angled position, and then across the vibrating surface with the spent anode assembly in the angled position. A second station is a scraping station positioned downstream of the vibrating station. The scraping station has at least one scraper to scrape the bath material from the carbon butt and stub.

Abstract: Metal castings, having a number of internal passageways which open at different surface portions of the castings, are mounted upon a horizontal axis wheel-like frame. The frame is intermittently rotated and momentarily stopped so that castings are rotated at times and stationary at times. During the times that the castings are stationary, they are simultaneously subjected to either an externally applied vibration or to a momentary, several millisecond long, high pressure burst of air through their respective passageways. The alternating vibrations and momentary bursts of air loosen and remove the sand and other casting debris contained within the passageways. Additionally, the changing angularity of the castings, due to the rotation, coupled with the vibrations and bursts of air, dislodge such sand and debris from the walls and, also, downwardly out of the passageways.

Abstract: In this method for removing spatter deposits accumulated upon the inner surface of the end portion of a tubular arc welding torch nozzle, an end portion of a welding rod being fed for arc welding through an end portion of this nozzle with a space being left between this welding rod and the inner surface of the end portion of the nozzle, an electrical current is supplied through an electromagnetic coil positioned longitudinally proximate to the end portion of the nozzle. This electrical current typically generates an electromagnetic force upon the spatter deposits in the general direction parallel to the central axis of the nozzle, thus removing such spatter deposits from the inner surface of the end portion of the nozzle.
