Abstract: There is provided a countermeasure defense system against hostile missiles by employing non-explosive intercepting (“NEI”) elements 14 deployed by the spin stabilized rocket 10. The NEI are carried in a payload section 17 and contained by a sleeve assembly 16 which is removed by a drive mechanism 20 or a pyrotechnic device 152 after a countdown time delay programmed into the trigger release assembly 46 as controlled by the control unit 150. The drive assembly includes a drive rod 26 that is releasably held by a release assembly 46 a compressed coiled spring unit 30 drives the sleeve assembly 16 forward exposing the payload section 17 to the centrifugal force of the spin stabilized rocket propelling the NEI elements out from the rocket at constant angular velocity creating an interceptor cloud of elements. In another embodiment the pyrotechnic device 152 detaches the shearable screws 170 that secure the payload section 117 from the rocket engine housing 102 thereby setting the sleeve 121 free from the rocket housing 102.

Abstract: A belt-driven tape cartridge with reduced tape pack deformation and more spatially homogeneous tape tension. The belt driven tape cartridge has a supply side tape hub and a winding side tape hub both rotatably mounted on the base. The tape is wound around the hubs to form a tape pack about each hub. A drive roller is rotatably mounted on the base. First and second rollers are rotatably mounted on the base. The drive belt is engaged on the drive roller, the tape pack on the supply side tape hub, the first and second corner rollers, and the tape pack on the winding side tape hub. The pack belt is engaged between the first and second corner rollers and disposed on the inner side of the drive belt. The drive belt has a width less than a width of the pack belt such that tape pack deformation is reduced and the tape tension is more spatially homogeneous.

Abstract: A pack belt or similar mechanism is provided in a two hub, belt-driven data cartridge to press against the tape pack on the take-up hub side of the cartridge when approximately half of the tape has wound onto that hub. The added load from this pressure reduces the speed of the tape-up hub, which in turn reduces the speed differential between the two hubs. Since the speed differential between the hubs causes a gradient in tape tension (bow-tie) as the tape is moved from BOT to EOT, this reduces or eliminates the bow-tie. Adjustment of the relative tensions between the drive belt and the pack belt allows adjustment of the bow-tie, ranging from the normal bow-tie, to near zero bow-tie, to a negative bow-tie. Coating one side each of the drive belt and the pack belt, then having the coated side of the drive belt contact the uncoated side of the pack belt further reduces bow-tie. Combining the pack belt with self-acting hydrodynamically lubricated guides significantly improves the efficiency of the cartridge/drive system at low tape travel speeds.

Abstract translation: 在两个轮毂皮带驱动的数据盒中设置包装带或类似的机构，当胶带的大约一半已经卷绕到该轮毂上时，压紧盒的卷取轮毂侧的带包。 来自该压力的附加负载降低了带式集线器的速度，这又降低了两个集线器之间的速度差。 由于当磁带从BOT移动到EOT时，轮毂之间的速度差会导致磁带张力（弓形）的梯度，所以这减少或消除了领结。 调整传动带和包装带之间的相对张力允许调整领带，从正常的领结到接近零的领结，到负的领结。 将驱动带和包装带的每一面涂覆，然后使驱动带的涂覆侧与包装带的未涂覆侧接触进一步减少蝴蝶结。 将包装带与自动加氢动力润滑导向器相结合，可以显着提高墨盒/驱动系统在低磁带行驶速度下的效率。

Abstract: Hydraulic piston pumps and motors are used in various applications to power implements, steering, propel, and auxiliary systems. However, it is important to keep the piston weight and compressible fluid volume low in order to have a smaller more efficient pump. The subject piston is manufactured in a simple manner to achieve a reliable, light weight design. The piston has a cylindrical body having an outer surface. The piston is manufactured by forming a first bore having a large diameter in the body extending from the outer surface and terminating at an annular shoulder. A second bore is formed which extends from the annular shoulder to a predetermined depth. A tube is inserted through the bore and extends a predetermined distance into the second bore. A cap has a bore and is positioned on the body in abutment with at least a portion of the outer surface. The cap slidably receives the tube through the bore. The cap is brazed to the body and the tube is brazed to the cap and to the body to form an isolated annular cavity in the piston.
