    Abstract: A MORE UNIFORMLY BONDED GLASS FIBER MAT THAN PRODUCED BY THE PRIOR ART IS OBTAINED BY CAUSING DROPLETS OF BINDER HAVING A PREDETERMINED AND GENERALLY UNIFORM SIZE TO PENETRATE A GAS FLOW CONTAINING THE ATTENUATED GLASS FIBERS AT AN ANGLE OF CONVERGENCE OF LESS THAN APPROXIMATELY 40 DEGREES. THE DROPLETS ARE UNACCOMPANIED BY GAS FLOW OTHER THAN THAT INDUCED BY THE DROPLETS. THE SIZE OF THE DROPLETS ARE SUCH THAT THEY ARE LARGE ENOUGH TO SURROUND THE JUNCTURE OF ABUTTING FIBERS BUT ARE SUFFICIENTLY SMALL THAT THEY WILL NOT PENETRATE THE VEIL. THESE DROPLETS ARE PROJECTED AT A VELOCITY GENERALLY EQUAL TO THE VELOCITY OF THE FIBERS OF THE VEIL.

    Abstract: Method and apparatus for distributing strands on a collecting surface aerodynamically. Embodiments of fluid nozzle and air foil members divert the strands after the strands have had a linear velocity imparted thereto to selected deposition points without touching the strands. A sweeping distribution of strands back and forth across a collection surface can be obtained by controlling the flow of fluid through the nozzle, controlling the air pressure between an air foil and a strand, by changing the angle of attack of an air foil, etc.

    Abstract: A FIBROUS BODY OF CONTINUOUS STRANDS UNIFORMLY DISTRIBUTED WITH RESPECT TO EACH OTHER, THE STRANDS HAVING THE FILAMENTS DISPERSED IN THE DEPOSITED POSITION OF THE STRAND. THE BODY IS FORMED OF STRANDS COMPOSED OF ONLY ENOUGH FILAMENTS TO GIVE EACH STRAND SUFFICIENT MASS TO BE PROJECTED TO A PREDETERMINED OR SELECTED AREA OF A COLLECTING SURFACE AT A BODY FORMING STATION. THE FILAMENTS OF EACH STRAND ARE THEN DISPERSED AFTER THE STRAND IS IN PLACE ON THE COLLECTION SURFACE.

    CPC classification number: F16F15/027

    Abstract: A pneumatic cylinder connected between an eccentric on a rock shaft and a structural support, for absorbing energy during one quarter of the cycle of the rock shaft during which it is decelerated, and for putting the absorbed energy back into the rock shaft during the next quarter cycle when it is accelerated. The pneumatic cylinder is preferably a double acting one with a center port to accomplish the energy absorption and redelivery to the rock shaft, at both ends of the shaft rocking movement. The rate of energy absorption and subsequent reapplication may be controlled by supplying superatmospheric pressure to the center port, and/or by starting the compressive cycle prior to the mid point of the oscillating cycle. The later is accomplished by using a piston--side port valving arrangement wherein the piston has a length that is a sizable proportion of its stroke. The cylinder may be cooled by utilizing a center exhaust port opposite the inlet port, and causing a continual flow through the low pressure end of the cylinder after the piston has proceeded past the inlet port. Bleeds may be provided at opposite ends of the cylinder to reduce the reapplication force of the cylinder, and adjustable chamber means may also be provided on one or both ends of the cylinder for adjusting the absorption rate.

    Abstract translation: 连接在岩石轴上的偏心轮和结构支撑之间的气缸，用于在岩石轴的减速的四分之一周期期间吸收能量，并在下一季度将吸收的能量放回到岩石轴中 循环加速。 气动缸优选是具有中心端口的双作用气缸，以在轴摇摆运动的两端实现能量吸收和重新输送到岩心轴。 可以通过向中心口提供超大气压力和/或通过在振荡周期的中点之前开始压缩循环来控制能量吸收速率和随后的再次施加。 后者通过使用活塞侧端口阀装置来实现，其中活塞具有其行程相当大比例的长度。 可以通过利用与入口相对的中心排气口来冷却气缸，并且在活塞经过入口之后引起连续流过气缸的低压端。 可以在气缸的相对端设置出血，以减小气缸的再次施加力，并且也可以在气缸的一端或两端设置可调节的腔室装置，以调节吸收速率。
