Abstract: A thick-walled, seamless, rigid non-porous conduit (Y) having a substantially uniform wall thikkness which is not less than about 0.5 percent of the outside diameter consisting essentially of an oriented crystalline thermoplastic polymer characterized by a structure comprised of radially compressed discrete, platelet-like spherulitic crystalline aggregates (A!) and having a combination of good ultimate tensile strength and low temperature tensile impact strength. The conduit is fabricated by solid state hydrostatic extrusion of a substantially non-oriented semi-crystalline thermoplastic polymer preform (X) which may contain up to about60 weight percent filler. The polymer is substantially simultaneously elongated in both circumferential and axial directions by compressive forces with the circumferential elongation being at least 100 percent. The apparatus used to produce the product is a hydrostatic extrusion press which includes an annular orifice in which the thermoplastic polymer is elongated substantially simultaneously circumferentially and axially with the circumferential elongation being at least 100 percent. Means for maintaining the rigidity of tooling and the hydrostatic extrusion fluid pressure while providing a film of the fluid on the preform for lubricity are provided in the apparatus. A sheet (F) substantially uniform in thickness and having substantially the microstructure and properties of the conduit and excellent drawability may be made from the conduit by slitting and heat deformation. Articles of manufacture may be made by solid state deformation processing of the conduit or the sheet, such as vacuum drawing.

Abstract: FIELD: chemical engineering. SUBSTANCE: nitric acid is recovered from raffinates containing acetic acid by means of rectification and/or scrubbing in column accompanied with withdrawing acetic acid into slightly acidic distillate produced by distilling acetic acid in a zone wherein vapor flow exceeds that of phlegm running down the plates. Acetic acid in this case is contained either in process solution fed onto one of the upper column plates or in secondary vapor produced from evaporation of this solution fed into the middle portion of column. Excess of vapor is created either by evaporating acetic acid-free process solution together with solution wherefrom acetic acid has been already distilled off, or by combining, in the rectification process, vapor flows originated from evaporation of the two solutions, or by additionally feeding water into the bottom of rectification column. Recovered concentrated nitric acid is obtained via its scrubbing by a separate water stream with subsequent removal from column plate, admixture-containing phlegm being transferred into column bottom by-passing scrubbing zone. EFFECT: enhanced efficiency of process.

Abstract: FIELD: maintenance of public order. SUBSTANCE: invention can be used in performance of operations for liquidation of mass disorders, detention of terrorists, in setting hostages free and so on including conditions of densely built town areas and special army operation. Method is based on maintenance of individual two-way radio communication between main radio station and peripheral radio stations of operators having electric communication with individual weapons of operators, on tuning of receivers of peripheral radio stations to frequency of transmitter of main radio station and on giving commands by voice with the aid of microtelephones to hit target or to act on it with the use of individual weapons. Transmitters of peripheral radio stations are tuned to individual frequencies. In response to received voice command to hit target operators ready to execute it press microswitches of radio stations located in close vicinity of trigger of weapon, disconnect their microtelephones from low-frequency outputs of radio stations, connect trigger mechanism of individual weapons to them and send corresponding signal to main radio station. Readiness signals of operators are summed up at main radio station and when their number reaches value specified in advance then tone signal which value is sufficient for simultaneous operation of trigger mechanisms of individual weapons of operators is sent to peripheral radio stations. In specific cases additional technical means are used to act on target. Action is started at moment of sensing of tone signal from main radio station or with some difference in time. Package of all stated indications makes it possible to enhance reliability and efficiency of method, to increase speed of execution of operations with the use of it, to ensure security of hostages during their release, to reduce expenses for realization of method. EFFECT: enhanced reliability and efficiency of method, ensured security of hostage during their release and reduced cost of realization of method.
