Abstract: Abstract of the Disclosure Friction Couple Cooling system Responsive to Actuation Thereof Cooling systems for friction couples such as clutches are useful, for example, in industrial vehicles that utilize large capacity clutches which generate large amounts of heat when the clutches are being engaged.  Other cooling systems either reduce or totally eliminate cooling flow during disengagement while adding additional flow for cooling during partial engagement but in these systems they normally maintain the additional cooling flow after full engagement.  In such cooling systems, the additional fluid flow being provided after full engagement results in unnecessary use of horsepower.  Furthermore, the additional flow is provided at a pressure level that also uses extra horsepower.  The present cooling system provides a limited flow rate to the clutches during disengagement and provides additional cooling flow to the clutches during partial engagement and controls the pressure level of the fluid from the source of cooling fluid by operation of a valve mechanism which is responsive to a control mechanism.  Upon full engagement, the valve mechanism automatically reduces the volume of cooling fluid to the clutches and simultaneously reduces the pressure level of the cooling flow from the source of cooling fluid.  This cooling system provides the needed volume of cooling fluid during partial engagement of the clutches and also reduces the volume of cooling fluid during disengagement to reduce drag forces while further reducing the volume of cooling fluid during full engagement to conserve horsepower.

Abstract: ABSTRACT OF DISCLOSURE   An insertion machine has a stationary table for holding inserts, and a linearly movable table for receiving and holding envelopes.  The moving table jogs left or right to align the insert and envelope 80 that the insert may be pushed into the envelopes a parallelogram drive mechanism has a first pair of belt drives which form vertical parallel arms.  As the table moves back and forth, the length of the parallel vertical drive mechanism does not change appreciably so that the ends of the vertical arms float up and down.  There is no need for sliding gears, shafts, or the like to transfer power to the table.  A second pair of belts drive the vertical belts from a stationary point at a center of the side of the parallelogram which is opposite the table.  The second pair of drive belts enables the lower ends of the first pair of drive belts to float up or down slightly without causing any dislocation as a result of table movement.

Abstract: ELECTRONICALLY-CONTROLLED GAS BLENDING SYSTEM                  Abstract of the Disclosure A gas blending system includes a proportional mixing valve having a valve element movable between first and second limits of travel corresponding to a minimum and maximum percentage, respectively, of one of the gases in the blended mixture.  The position of the valve element is detected by a detection mechanism, producing a position signal inputted to a microcomputer.  The microcomputer also receives a control signal representing a desired percentage of one of the gases to be blended.   The microcomputer calculates a desired valving element position as a function of the value of the control signal, and generates a drive signal as a function of a comparison made by the microcomputer between the detected valve element position and the desired position.  A motor drives the valve element to the desired position in response to the drive signal.  The system also includes an accumulator for accumulating a selected volume of gas mixture flowing from the outlet of the valve prior to delivery of the mixture to a downstream demand.   The accumulator increases the effective peak flow rate capacity of the system, while "smoothing out" instantaneous changes in downstream flow rate demand before the effects of such changes are experienced at the valve.
