摘要： A soft protective construction for body protection, such as a bullet-proof vest or shirt is disclosed wherein a double layered bullet-stopping arrangement of mutually moveable rectangular or square protective plates is provided which plates can preferably be inserted into pockets of a carrier material. The outer layer of plates lying on the bullet impact side consists of steel and at least in portions thereof said outer plates are overlapped in scale-like fashion. The inner plate layer, which lies closer to the body than does the outer layer, is designed to absorb or largely destroy the impact energy of a striking bullet. The protective plates of the inner layer next to the body comprise a thick shock absorbing material, in particular a plastics material, such as polyamide, and said inner plates are arranged in a common plane and are joined together in a form-locked manner along the horizontally oriented, meeting plate edges by slide joints (5) and along the vertically oriented and likewise meeting plate edges by rotating joints (6, 11, 16, 17, 22, 23, 24). Preferably, the inner layer plates comprise a casting polyamide obtained by an activated anionic polymerization of monomeric laurolactam which has a Vicat B softening point of not less than about 183.degree. C., preferably about 160.degree. C. to 168.degree. C.

摘要： An improved method for the production of castings by the anionic polymerization of lactams, particularly lauric lactam, in which two melts prepared separately, one with a catalyst and one with an activator, are polymerized together in a mold heated to substantially the same temperature as the melts, is described, the improvement comprising the application of a vacuum in the range from about 80 to 450 Torr, said vacuum being selected in accordance with the formula S.times. T= K where S is the surface area of the casting exposed to the vacuum, V is the volume thereof, T is the vacuum application time and is less than the polymerization time and K is a constant. Said vacuum is replaced by ambient pressure either progressively or instantaneously when the polymerization mixture reaches a highly viscous non-stirrable state. Thereafter, the polymer may be heat treated at a temperature about 10.degree. to 20.degree. C. below its crystallization melting range if desired during completion of the polymerization to inhibit the formation of shrinkage blow holes. The mold is preferably gas-tight.
摘要翻译：通过内酰胺，特别是月桂酸内酰胺的阴离子聚合制备铸件的改进方法，其中分别制备两种熔体，一种具有催化剂和一种具有活化剂的熔体，在加热至基本相同温度的模具中聚合在一起熔体，描述了改进，其包括施加在约80至450乇范围内的真空，所述真空根据公式Sx T = K选择，其中S是暴露于真空的铸件的表面积， V是其体积，T是真空施加时间，并且小于聚合时间，K是常数。当聚合混合物达到高粘度不可搅拌状态时，所述真空被环境压力逐渐地或瞬时地替代。此后，聚合物可以在聚合完成期间，如果需要，在低于其结晶熔融范围的温度约10℃至20℃下进行热处理，以抑制形成收缩气孔。模具优选是气密的。

摘要： A split ring seal of a centrifugal pump comprises two rings that consist of a sintered material and that are respectively connected in a frictional or positive manner to a front cover disk of the impeller and to the pump housing which are made of a cast polyamide as produced by the activated anionic polymerization of monomeric laurinlactam.
