Abstract: This invention pertains to an apparatus for producing glass fibers which includes a bushing having openings, a winder, and an elongated member positioned to engage a strand located between the bushing and winder. This member is extended and flexible and bends upon engagement with a moving strand setting up a stress in the member which raises the resistance of the member. The resistance is measured by a bridge and a signal is sent to the winder which may stop the winder or regulate the speed of the winder in response to the strain of the member.
Abstract translation: 本发明涉及一种用于生产玻璃纤维的装置，其包括具有开口的衬套，卷绕器和细长构件，定位成与位于衬套和络纱机之间的绞合线接合。 该构件被延伸和柔性，并且在与移动的线接合时弯曲，在构件中设置应力，从而提高构件的阻力。 电阻由桥测量，并且信号被发送到卷绕机，该卷绕机可以响应于构件的应变而停止络纱机或调节卷绕机的速度。

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE LEVEL OF A BODY OF MATERIAL IN A CONTAINER WHEN REPLENISHING MATERIAL REMOVE FROM THE BODY, BY SENSING LEVELS OUTSIDE OF A PREDETERMINED RANGE OF LEVELS OF THE MATERIAL, INCREASING THE RATE OF FEED OF THE REPLENISHING MATERIAL BY AN AMOUNT PROPORTIONAL TO THE TIME THE LEVEL IS BELOW THE RANGE, AND DECREASING THE RATE OF FEED OF THE REPLENISHING MATERIAL BY AN AMOUNT PROPORTIONAL TO THE TIME THE LEVEL IS ABOVE THE RANGE. THE PREVENT OSCILLATION OF THE SYSTEM AND ATTAIN STABILITY THE RATE OF FEED IS FURTHER INCREASED BY
A PREDETERMINED CONSTANT AMOUNT WHEN THE LEVEL IS BELOW THE RANGE, THIS FURTHER INCREASE IN FEED RATE BEING REMOVED WHEN THE LEVEL RETURNS TO THE RANGE. THE RATE OF FEED IS FURTHER DECREASED BY A PREDETERMINED CONSTANT AMOUNT WHEN THE LEVEL IS ABOVE THE RANGE, THE FURTHER DECREASE IN FEED RATE BEING REMOVED WHEN THE LEVEL RETURNS TO THE RANGE.-
