Abstract: Torque is distributed by calculating first and second torque commands using a requested torque and a ratio of speeds of first and second wheels and limiting them in accordance with respective torque command approved ranges and approved change rates; converting the limited torque commands to horsepower commands and limiting them in accordance with respective horsepower command approved ranges and approved change rates; and converting the limited horsepower commands to present torque commands. Maximum horsepower available is determined by using an engine speed to determine a nominal amount of available horsepower; applying a desired load status signal and an actual engine load status signal to a proportional-integral A regulator; and using the nominal amount of available horsepower and an output signal of the regulator to determine the maximum amount of available horsepower.

Abstract: A particulate removal assembly for a fluid distribution system comprising a particulate collection chamber having an inlet through which particulate and fluid enter said collection chamber; a detector for sensing when said chamber has fried to a preselected degree with particulate; said chamber having an intermittent discharge responsive to said detector whereby the particulate is flushed from said chamber. The particulate removal assembly for a fluid distribution system further comprising a closure member for said intermittent discharge; said closure member actuated by fluid pressure delivered from said collection chamber.

Abstract: An eye spud designed for use in removing foreign objects embedded in or adhering to the surface of the eye globe with minimal risk of infection or physical damage of the eye globe.

Abstract: An improved universal eye patch which may be successfully applied to either the right or the left eye. The eye patch comprises a central portion, preferably non-yielding, which serves to provide support to an underlying pad, and wing portions that extend angularly from the central portion and serve as means for securing the patch in position over the eye orbit. In the preferred patch, the wing portions are elastically stretchable in a direction away from the central portion and bear adhesive on their respective surfaces disposed in contact with the face so as to anchor the patch and maintain it tautly in position over the eye orbit.

Abstract: A protective device for integrated circuits and the like which protects the circuit from static charges and induced voltages resulting from static charges and otherwise. Electrical connections are made to the leads of the circuit terminating in non-contacting relationship within a chamber filled with an ionizable gas. A conductive material is spaced equally on the terminations and connected to the lowest potential of the circuit, typically ground. Over voltages from static charges and the like cause the gas to ionize and discharge the over voltage. A second shield of conductive material is disposed between the gas filled chamber and the circuit and, in turn, connected to an independent point within the chamber. Fields produced as a result of a static discharge, or otherwise, which otherwise would induce over voltages into the circuit cause an induction voltage into the shield material which voltage is then discharged through the ionizable gas.
