Abstract: This invention relates to reticulated elastomeric matrices, their manufacture, their post-processing, such as their reinforcement, compressive molding or annealing, and uses including uses for implantable devices into or for topical treatment of patients, such as humans and other animals, for surgical devices, tissue augmentation, tissue repair, therapeutic, nutritional, or other useful purposes.

Abstract: A two-speed motor drives a shaft carrying the horse-leading radial arms of a rotary mechanical hot-walker for cooling out horses at a slow walk or exercising horses at a trot. Speed-reducing mechanism for the motor includes two open V-belt drives connecting a constant speed ratio gearbox between the motor drive shaft and the shaft carrying the hot-walker arms. One of the open V-belt drives includes a variable pitch pulley the operation of which, in combination with the two motor speeds, enables the rotative speed of the radial horse-leading arms to be at least almost infinitely adjustable throughout the entire wide range from a slow walking speed, when the motor is operating at its low speed, through a fast trotting speed, when the motor operating at its high speed. Belt tension adjusting mechanism is provided for the other open V-belt drive for adjusting the value of the maximum torque transferable by such other open V-belt drive at any rotative speed of the hot-walker rotor.
