    Abstract: Various technologies described herein pertain to an adjustable compliance apparatus. The adjustable compliance apparatus includes a shaft, a sleeve element, and a torsion spring. The sleeve element includes a bore there through, where the shaft is positioned through the bore of the sleeve element. Further, the torsion spring includes a plurality of coils, where the shaft is positioned through the plurality of coils. Moreover, the sleeve element is slidable in an axial direction along the shaft between the torsion spring and the shaft.

  • Patent number: 8056656
    Abstract: This invention relates to a traction assembly for a vehicle which uses an endless traction band and a plurality of wheels for propulsion. More particularly, the traction assembly comprises a sprocket wheel which has a different size and number of sprocket teeth depending on whether the traction kit replaces the front wheels or the rear wheels of the vehicle. The sprocket wheel of the traction kit can also be configured such that its sprocket teeth are laterally offset. The traction kit can also comprise an anti-torque system that prevent physical contact between the traction kit and the vehicle and that can bias the position of the traction kit in order to improve the steering performance. Finally, the traction assembly can comprise a pivotable extension which lengthens the traction assembly and improves its traction capabilities.

  • Patent number: 7441980
    Abstract: A device for joining a first component A and a second component B while leaving a joining gap SP includes a bolt 4 and a compensating coil 2 for compensating tolerances of the joining gap. The compensating coil is adapted to be fixed to the bolt 4 by frictional engagement means and/or releasable positive engagement means. The dimensions of the compensating coil are adapted to a helical rim hole portion 6 of the first component A such that actuation of the bolt 4 causes the compensating coil to rotate through the helical rim hole portion until it fills the joining gap for the purpose of tolerance compensation, and the frictional engagement means and/or releasable positive engagement means is overcome by further actuation of the bolt 4 so that the bolt can be screwed into a threaded hole of the second component B to join the two components.

    Abstract: A rolling device for supporting a roll of toilet tissue and for containing an air-treating substance. The device includes a pair of axially aligned body members forming an elongated cage for the air-treating substance, such body members being spread apart and adjusted in their relative axial positions by a spring which is compressible therebetween and made of a material which undergoes stress relaxation at ambient temperatures such that it readily takes a new set upon mounting. The body members each have an axial protuberance extending from an end surface, such end surfaces preferably being somewhat convex to help minimize the bearing surface of the device with the socket structures in which it is mounted. The air-treating material is preferably in beads free to tumble as the cage is rotated. The spring is preferably a polyolefinic material and preferably includes helical strands extending around the cage. The strands preferably have reduced cross-sections near their ends.
