Abstract: The subject of the invention is a method of manufacturing centrifuged, glass fiber-reinforced synthetic material pipes wherein liquid, curable resin, which contains a filler, together with glass fibers, additives for the curing process, possibly also with sand, is introduced into a rotating mould and the temperature of the mould is between 40° C. and 75° C. as the raw materials are introduced. The resin used in the layers in the outer region of the pipe has a gel time which is equal to or greater than the gel time of the resin used for the inner region of the pipe and the resin comprising a filler content of at least 40% is used. Furthermore, once the exothermal reaction has commenced, warm water is sprayed onto the mould in order to maintain the temperature of the mould at least at 60° C. until the pipe is removed.

Abstract: Hollow polymeric structures with unique morphologies are manufactured with a rotational spinning technique wherein phase separation of soluble solutions is induced within a filled mold as it is rotated. As phase-separation occurs, an increase in density of one phase results in sediment at a periphery under centrifugal forces and after or during sedimentation, gelation of phase-separated particles fixes a tube morphology. By controlling the rotational speed and the formulation chemistry, the tube dimensions and wall morphology can be manipulated. The method requires small quantities of starting material, permits multi-layering of tubes, is applicable to diverse polymers and results in highly diffusive hollow structures while maintaining good mechanical strength.

Abstract: In a process of making a rotationally symmetrical article, such as rope pulleys, running wheels or the like, from plastic material such as cast polyamides, raw material melts of plastic material and predetermined amounts of catalysts, activators and stabilizers are prepared at different formulation and composition to impart the melts with different mechanical strengths after polymerization. The raw material melts are poured into a heated, rotating mold in succession in dependence on a polymerization pattern of the raw material melts. After complete polymerization of the melts, the mold is opened, and the finished article can be removed from the mold for optional refinishing procedure.

Abstract: A process and apparatus for forming a seal between a filter cartridge wall and a pleated filter disposed within the cartridge having a support for rotating the cartridge. A nozzle is connected to a source of sealant for injecting sealant into an area between the wall of the cartridge and the filter media. A valve connected to the nozzle valves sealant to the nozzle and has a draw back feature after a desired amount of sealant is injected. The method for sealing the filter media to the wall of the cartridge includes rotating the filter cartridge while disposing a nozzle into the interior of the cartridge and injecting a sealant through the nozzle controlled by a valve. The valve draws flow backwardly from the nozzle at the termination of the injection of sealant.
