摘要： A robust polyurethane liner is disclosed for solid propellant rocket motors which is insensitive to large variations in stoichiometry, exhibits increased cohesive strength and, when used in combination with a unique two coat (wet coat) liner process described below, modifies the ballistic properties of the adjacent interfacial propellant layer. The liner compositions include a polymeric binder having a plurality of reactive hydroxyl functional groups and a curing agent having a plurality of reactive isocyanate functional groups. The quantity of binder and curing agent is selected such that the NCO/OH ratio is in the range from 1.5 to 4.5. Diisocyanate curing agents are particularly useful. A bonding agent, such as a polyfunctional aziridine compound, is typically present in the liner composition in an amount ranging from about 3% to about 5%, by weight. An oligomer catalyst is included in the liner composition in an amount ranging from about 15% to about 50%, by weight. Diammonium phosphate ((NH.sub.4).sub.2 HPO.sub.4) functions as an oligomer catalyst and as a ballistic modifier to inhibit propellant burn rate when the liner is cured concurrently with the propellant. A colorant, such as rhodamine B, may optionally be included to assist in determining coverage or thickness of the liner coating.

摘要： The present invention concerns an erosion resistant, low signature liner for solid propellant rocket motors and rocket motors having such a low signature liner. The liner combustion products in the exhaust plume have low visibility in the IR and visible light spectra which is essential for use in low signature solid propellant rocket motors. The liner also forms an in-situ protective layer at elevated temperatures for enhanced erosion resistance. These erosion resistant properties eliminate the need for supplemental case insulation which would contribute additional smoke and combustion products to the exhaust plume as well as add additional costs and inert weight to the motor.
摘要翻译：本发明涉及用于固体推进剂火箭发动机和具有这种低签名衬垫的火箭发动机的抗侵蚀，低签名衬垫。排气羽流中的衬里燃烧产物在IR和可见光光谱中的可见度低，这对于使用低签名固体推进剂火箭发动机是必不可少的。衬垫还在高温下形成原位保护层，以提高耐侵蚀性。这些抗侵蚀性能消除了对补充壳体绝缘的需要，这将对排气羽流产生额外的烟雾和燃烧产物，并且对电动机增加额外的成本和惰性重量。

摘要翻译：公开了用于固体推进剂火箭发动机的坚固的聚氨酯衬垫，其对化学计量的大变化不敏感，表现出增加的内聚强度，并且当与下述独特的两层（湿涂层）衬垫工艺组合使用时，改变了相邻的界面推进剂层。衬垫组合物包括具有多个反应性羟基官能团的聚合物粘合剂和具有多个反应性异氰酸酯官能团的固化剂。选择粘合剂和固化剂的量使得NCO / OH比在1.5至4.5的范围内。二异氰酸酯固化剂是特别有用的。粘合剂，例如多官能氮丙啶化合物，通常以约3重量％至约5重量％的量存在于衬里组合物中。衬垫组合物中包含的量为约15％至约50％的低聚物催化剂。磷酸二氢铵（（NH4）2HPO4）作为低聚物催化剂，作为弹道改性剂，当衬垫与推进剂同时固化时，可以抑制推进剂燃烧速率。可以任选地包括着色剂，例如罗丹明B，以帮助确定衬里涂层的覆盖度或厚度。

摘要： A mounting bracket for an axial separator rotor tooth. The bracket is provided with extended portions that are welded to the rotor tube. Extending radially outward from the extended portions are bracket legs. A middle portion extends between the bracket legs and is provided with a bolt locating slot. A central enlarged opening is formed in the bolt locating a slot. The head of a mounting bolt, for bolting the tooth to the bracket, can be inserted through the enlarged opening. As the mounting bolt is moved outwardly from the enlarged opening the bolt head is captured between the middle portion of the bracket and the rotor tube.

摘要： Classifying apparatus and methods for the separation of solids of differing sizes includes a screening deck having an inclined frame and a screen in the frame on which the solids are deposited and moved downwardly. A plurality of beams extend beneath the screen transversely of the frame and the ends of the beam are mounted to the frame by a resilient mounting to isolate vibrations of the beam from the frame. A tappet assembly is fixed to each of the beams and contacts the underside of the screen and a vibrator motor is mounted to each of the beams to directly vibrate the beam, the tappet assembly of each beam, and the screen. Controls may be provided for independently operating each of the vibrators to vary one or both of the frequency or the amplitude of the vibrations of the screen over its length. The screen preferably includes a plurality of screen portions which are crowned transversely of the frame by the tappet assemblies, and the tappet assemblies include a pair of spaced parallel bars of continuous length extending transversely of the frame and in contact with the screen.
