Abstract: A swing arm for managing a power cord to an electric vehicle has a proximate arm member with a pivotable connection about a vertical axis for connection to the vehicle in proximity to a longitudinal center line of the vehicle. A distal arm member is pivotably connected about a pivot vertical axis to the proximate arm member and resiliently biased to extend straight out with respect to the proximate arm member. The swing arm is dimensioned to extend the distal arm member beyond a side of the vehicle when the swing arm extends laterally with respect to the vehicle. A spring member is connected to the distal arm member for resiliently biasing the distal arm member to extend straight out with respect to the proximate arm member against a side force below a predetermined amount and yieldable to bending of the distal arm member upon exertion of a side force above the predetermined amount.

Abstract: The invention is a riding floor polishing and grinding machine that uses one or more gangs of polishing heads (242) to treat concrete and similar surface flooring (208). A compact vehicle (210) equipped with a front loader arm (235) is fitted with a module (240) containing the gang(s) of polishing head. The vehicle (210) is capable of raising and rotating the module to easily change the pads attached to the polishing heads. Each polishing head is individually powered by a motor and floats over the floor surface. The pads attached to the polishing heads can be of many different types, preferably diamond-impregnated polishing pads. The invention enables operator to more quickly and efficiently remove material from a floor surface. The design also enables gangs of pads to be mounted with different grit ratings to perform different treatment operations using a single machine in a single pass over a floor surface.

Abstract: A wheel cleaning device for cleaning and/or polishing a rim or any other exposed part of the wheel during traveling of the vehicle. The device includes a mounting support for securing the device to the wheel axle so as to be in a stationary relationship relative to the wheel and a cleaner having a shaft and a brush. The shaft has a first end rotatably connected to the support for continuous rotation relative thereto about the rotation axis of the wheel and a second end extending radially from the first end. The brush mounting on the second end of the shaft is positioned, configured and sized to contact the wheel. The brush depends downwardly from the support under gravity to continuously rub against the wheel to clean the wheel under rotation during traveling of the vehicle.

Abstract: A wheel cleaning device for cleaning and/or polishing a rim or any other exposed part of the wheel during traveling of the vehicle. The device includes a mounting support for securing the device to the wheel and a cleaner having a shaft and a brush. The shaft has a first end freely pivotally connected to the support to pivot about an axis of the wheel and a second end radially extending therefrom. The brush is mounted on the second end of the shaft such that it freely hangs down from the support under gravity to rub against the wheel and clean the same during the traveling of the vehicle.

Abstract: The grinding machine comprises A grinding head with a rotary abrasive tool, carried by a chassis equipped, at its ends, with rollers for running and. guiding on the rail that is to be ground. A balancing assembly, resting on the other rail of the track, is mounted to pivot on the chassis, also provided with an orientable maneuvering arm. To rotate the grinding tool, an internal combustion engine is fixed to a support articulated to the balancing assembly, the horizontal output shaft of the engine being connected by a transmission assembly to the grinding head. The machine makes it possible to grind the profile of the head of the rail through an angle of 180° while at the same time avoiding excessive inclination of the engine.

Abstract: A grinding arrangement for grinding knives of a chopper drum of a forage harvester includes a movement arrangement for effecting movement of a grinding stone over the length of each of the knives, where individual locations of the knives can be associated with differing grinding times in order that the knives be ground to produce a desired cylindrical profile. A control for the movement arrangement may include either a sensor for determining the need for grinding a given knife at a precise location along the knife and the grinding time required for achieving a desired profile, or predetermined information stored in memory which operates to automatically cause a certain amount of grinding time to elapse in accordance with a specific axial position of the grinding stone.

Abstract: A chopper drum includes a plurality of knives distributed along its width and about its circumference. A grinding device is provided for automatically sharpening the knives, with a grinding stone of the grinding device having its movement automatically controlled by a microprocessor, which receives signals from an actual shape sensor and compares it with a stored desired shape and generates control signals, such that it shapes the profile of the chopper drum to at least approximate the desired shape.

Abstract: A brake pad operates to both resurface the braking surface of a rotor, and then automatically continue functioning as a normal brake pad. The rotor resurfacing is accomplished on the vehicle, employing all the components of a vehicle brake assembly, creating a perfect fit of the rotor and brake pad surfaces. In one embodiment, the brake pad includes a backing plate, a first plane of frictional material on the backing plate, and a second plane of frictional material mounted over the first plane of frictional material. The second plane of frictional material includes abrasive strips, each of the strips being separated from an adjacent one of the strips by a region of the first plane of frictional material. Preferably, the second plane of frictional material removes material from a rotor, when the brake pad is in frictional engagement with the rotor.

Abstract: An abrasive block 1 used for scraping wet leaves, snow or ice from a rail R of a railway track in order to enhance traction, is urged onto the rail R by a piston 2 under oil-pressure within a cylinder 3. The pressure is created via a diaphragm 11 which separates the oil in the cylinder 3 from an air-chamber 12. Chamber 12 is supplied with air via a regulator 14, from the air-brake supply system 16 of the train, and has a dump valve 19 for dissipating air-pressure surges. A return spring 20 under the piston 2 is active in retracting the block 1 when air-pressure in the chamber 12 is reduced.
