Abstract: A tube gripper device includes a one-piece gripper assembly of plastic material having a base portion and a plurality of gripper fingers extending therefrom in spaced apart parallel relation to each other for individual flexing movement relative to the base. A cam member is slidably engageable with each of said fingers and is connected to a solenoid actuator whereby upon energization of the solenoid actuator, the cam member is moveable to spread the fingers apart. A spring is provided for moving the fingers into gripping engagement with a tube upon de-energization of the solenoid actuator.

Abstract: An arrangement for improving the transfer of heat from a heat source to a heat sink. The improvement is provided by the use of a malleable dimpled wafer which is deformed between the heat source and heat sink so as to improve the direct contacting of the juxtaposed adjacent surfaces of the heat source and heat sink, thereby resulting in improved thermal conductivity therebetween.

Abstract: A control system for moving a large machine along a single axis. The control system includes first and second position loop servo systems to drive at least respective first and second motors to move respective first and second sides of the machine in the direction of the single axis. The control system is comprised of means responsive to position error signals generated by each position loop servo system for generating a difference error signal that is indicative of the difference between the actual position of each respective side of the machine along the single axis, and means for coupling the difference error signal to means for driving at least one of the motors for causing a change in movement of that motor in a direction to move each side of the machine toward the same actual position while at the same time causing the difference error signal to be reduced toward zero.
