Abstract:
A self sealing vessel assembly for high pressure microwave assisted chemistry is disclosed. The vessel assembly (10) includes a polymeric cylinder (12) and a circular polymeric cap (13) for the cylinder, the cylinder being closed at one end and open at the other end to receive the cap. The open end of the cylinder has a lip (20) that is beveled inwardly from the open end, and the circular polymeric cap (13) has a beveled lower edge (21) that engages the beveled lip (20) when the cap (13) is placed upon the polymeric cylinder (12). For high pressure applications, a choke cylinder (22) depends from the beveled lower edge (21) of the cap, and has an outer diameter substantially the same as the inner diameter of the polymeric cylinder (12) so that the choke (22) provides a self sealing mechanism for the cylinder as pressure from a chemical reaction increases within the cylinder. A composite sleeve (11) surrounds the polymeric cylinder (12), and includes at least one wound fabric layer (24) in which the winding is selected from the group consisting of filaments and yarns. A supporting frame (14) extends along the cylinder (12) and across the lid (13) and across the closed end of the cylinder, and prevents the lid from being displaced from the cylinder when pressure is generated inside of the vessel.
Abstract:
A novel hydrogenation reactor, hydrogenation methods implemented therein, and in general the use of said reactor, are disclosed. The reactor comprises a double wall consisting of an outer wall (10) capable of withstanding mechanical loads, and an inner wall (20) defining the reaction space (30) in which a reaction medium is reacted. Said inner wall (20) is resistant to said reaction medium and protects the outer wall (10) from any contact therewith. A space (50) is provided between said outer (10) and inner (20) walls to enable controlled recombination of the atomic hydrogen to be diffused through said inner wall (20). Said space (50) contains no means that might cause diffusion of said atomic hydrogen from the inner wall to the outer wall, and the reactor structure includes means that, in use, balance out the pressure on either side of said inner wall (20) and thus enable the hydrogen that has entered said space (50) to be circulated and removed from the reactor.

PURPOSE: To make it possible to receive a large load of axial force generated by a high pressure in a vessel under smooth and reliable resistance, by utilizing compression provided by a cotter or pin transversely inserted through the vessel and a flexible member entirely wound around the vessel. CONSTITUTION: There is provided at an axially lower end of a vessel 13 a cotter 17 inserted radially transversely through the vessel 13 by an inserting means such as a hydraulic cylinder 22 as a structure of receiving a load of axial force generated by a super high pressure, etc. in the vessel. The vessel 13 and upper and lower yokes 14 and 15 are integrally assembled, and they are formed with outer peripheral grooves 13b, 14b and 15b circularly extending in parallel relation with an axial direction of the vessel. Flexible members 18 and 18' such as a piano wire and wire steel band are fitted in the outer peripheral grooves 13b, 14b and 15b, and are wound around the assembled vessel and yokes along an entire axial length. With this arrangement, the vessel 13 and the yokes 14 and 15 are integrally tightly connected with each other and are generally provided for precompression. COPYRIGHT: (C)1984,JPO&Japio
Abstract:
PURPOSE:To facilitate lining application by a method wherein a groove is formed to a backing metal arranged in the vicinity of a butt welded part of a corrosion resistant lining of a container to be communicated with a detecting hole and an embedded plate is provided to a back surface of the lining to rapidly and certainly detect leakage of a content. CONSTITUTION:To a backing metal 8 arranged to a butt welded line 9 of a corrosion resistant lining 7 of a pressure container, grooves 12 are provided and holes 13 communicated with detecting holes 10 are formed to said grooves 12. Further, an embedded plate 14 such as a carbon steel plate or the like having a thickness same to that of the backing metal 8 is provided to a total surface except the baking metal of a back surface of the lining 7 and attached to a cylinder 5 by welding or the like. By this mechanism, when leakage is generated from the welded part 9, a leaked content is reached to the detecting hole 10 through the communication hole 14 and the groove 12. Therefore, before corrosion of the cylinder 15 is not advanced, leakage of the content is certainly detected. Further, by attaching the embedded plate 14, manipulation bending the lining at the butt welded part is not necessitated and application property and close adhesiveness of the lining a are enhanced.
