Abstract: A method of treating parts (34) in a treatment chamber (33) by hot-isostatic pressing with an inert gas as pressure medium and in the presence of a purifying agent (25a) for the inert gas comprises the steps of reducing the pressure in the treatment chamber (33), increasing the pressure again by introducing the inert gas, increasing the temperature in the treatment chamber (33) by activating heating elements (9a), and, after a certain holding time, reducing the pressure and the temperature again. Especially if the purifying agent (25a) is of the same material as the parts (34) being treated, the purifying effect of the purifying agent becomes insufficient. The effect of the purifying agent (25a) is improved according to the invention by bringing the inert gas, at least when being introduced, to circulate such that it is heated, passes through the purifying agent and is thereafter cooled before contacting the parts. The invention also relates to a device for carrying out the method.

Abstract: An increased efficiency method and apparatus for lining a section of pipe with a cement mortar. After a wet cement mortar has been applied to a cleaned interior surface of a pipe, carbon dioxide is introduced into the freshly lined section of the pipe in such quantity that a crust of calcium carbonate will be formed on the interior surface of the wet cement mortar lining as the carbon dioxide reacts with calcium compounds of the wet cement mortar in a relatively short period of time. This crust is provided to protect the underlying mortar from scouring, while tolerating a low-velocity flow of water, until the normal hardening of the underlying mortar through hydration can take place so as to substantially reduce the out-of-service time of the section of pipe which is being lined.

The principle of the invention resides in the fact that the same concentrations of volatile components present in the polymerization mixture are also present in the gaseous state within a protective gas maintained above the free surface of the polymerization mixture, the gaseous volatile components being in the equilibrium state with those in the polymerization mixture at polymerization temperature. The apparatus includes a main pipe branch which introduces a pure protective gas into a polymerization apparatus and at least one auxiliary pipe branch for saturating the protective gas with a volatile component.

Abstract: Apparatus and a process for bonding a core member to a housing member, particularly, in instances in which the members do not mate in a contiguous fashion. The invention includes some manual and some semi-automatic functions, but is largely automated and computer controlled. A conveyor carries an assembly of an initially joined but unbonded core member and housing member along a series of discrete stations. After some preparatory steps in the process, an initial continuous bead of sealant is first applied on one side of the assembly to close off the space between the members and thereby form a cavity between them. The bead is cured, then the assembly is inverted and the cavity is filled with an anaerobic bonding material. A second continuous bead of sealant is then applied on the other side of the assembly to close off the remaining space between the members as well to isolate the bonding material within the cavity.

Abstract: An apparatus and method for aseptic, particle-free production of articles. A shroud is placed around at least a portion of the device which produces the articles to substantially isolate that portion from the external environment. The device for producing the articles and the shroud are sterilized and the air inside the shroud is filtered and sterilized. A laminar or other type of flow of filtered, sterilized air is imparted through the shroud over the articles being produced. A secondary shroud encloses the corridor or work area adjacent the shroud and device which produces the articles. The corridor and secondary shroud are sterilized, and sterilized and filtered air is continually introduced therein. The articles therefore are particle-free and sterilized for further use. The apparatus and method can be used for any component production process employing high temperatures and/or pressures, including, but not limited to, blow molding, injection molding, and production of semiconductor electronic components.
