Abstract: A treadmill (10) includes a frame (12) on which are rotatably mounted first and second transverse roller assemblies (14, 16). An endless belt (18) is trained around the roller assemblies. A deck (20) is supported between the upper run of the belt and the frame by a plurality of rectilinear-shaped elastic cushions 100 that are reversibly deformable under the load imposed on a deck by the footplant of the treadmill user. The cushions 100 are not of uniform cross-section; rather, one or both of the ends of the cushions are relieved so as to present a nominally reduced cross-sectional area against the frame and/or deck. As the cushion is compressed from the load imposed on the deck, the cross-sectional area of the cushion providing resistance to further deformation/deflection of the cushion increases thereby increasing the resistance or stiffness of the cushion to further deformation and thus further travel of the treadmill deck (20) towards the frame (12).

Abstract: A composition for forming an antimicrobial artificial nail, a method for preparing the same, and a method for treating a microbial infection of a nail plate are provided. The composition comprises a binder component; a filler component which polymerizes to form an acrylic matrix subsequent to contact with the binder component; and an antimicrobial agent available for diffusion from the acrylic matrix.

Abstract: Method and apparatus for recovery of waste heat from thermomechanical pulping systems and the like in which waste heat in the form of steam exhausted from the mechanical pulper and latency chest portions of the thermomechanical pulping system are respectively passed through first and second evaporators which increase the enthalpy of the working liquid. The working fluid outputted from the first evaporator passes through a first compressor to significantly increase both pressure and temperature and further increase enthalpy. The working fluid at the outlet of the first compressor then undergoes desuperheating within an intercooling tank. The liquid phase of the working fluid is passed from said tank to the inputs of both evaporators, while the vapor phase merges with the working fluid outputted from the second evaporator and enters a second compressor to undergo further increases in pressure and temperature.

Abstract: A method and apparatus for electronically monitoring the condition of an object which normally emits stationary stochastic signals is disclosed wherein electronic signals representative of the emitted signals are generated in a plurality of at least two frequency bands and the kurtosis coefficient for these signals is determined over a period of time. Variations of the kurtosis coefficient are detected to provide an indication of the condition of the object.
