    Abstract: Apparatus and process for sterilizing and drying products comprising a first step of autoclaving and a second step of cyclic pressurizing with a substantially dry contaminant-free gas. The second step obviates the problem of recontamination after sterilization and permits drying at lower than conventional temperatures.

    Abstract: The present invention concerns a device for measuring the pressure and temperature in at least one pressure-tight analysis vessel, that has been sealed by means of a lid, whereby heat is supplied to the analysis vessel by means of a microwave oven. The device comprises a measurement device that is connected to a unit for controlling the microwave oven. In this regard, the measurement device is arranged in a microwave-tight housing inside the microwave field that is produced by the microwave oven. The housing is constructed in such a way that it forms a shield that is impermeable for the microwave field. A microwave-free zone is produced inside the housing. Electronic, current-carrying components can be arranged in the microwave-tight housing without, as a result, generating interference in the microwave field.

    Abstract: A process for hydrothermal oxidation of combustible materials in which, during at least a part of the oxidation, corrosive material is present and makes contact with at least a portion of the apparatus over a contact area on the apparatus. At least a portion of the contact surface area comprises iridium, iridium oxide, an iridium alloy, or a base metal overlaid with an iridium coating. Iridium has been found to be highly resistant to environments encountered in the process of hydrothermal oxidation. Such environments typically contain greater than 50 mole percent water, together with oxygen, carbon dioxide, and a wide range of acids, bases and salts. Pressures are typically about 27.5 to about 1000 bar while temperatures range as high as 800.degree. C.

    Abstract: A high temperature high pressure furnace has a hybrid partially externally heated construction. A metallic vessel fabricated from an alloy having a composition of at least 45% nickel, 15% chrome, and 10% tungsten is utilized (the preferred alloy including 55% nickel, 22% chrome, 14% tungsten, 2% molybdenum, 3% iron (maximum) and 5% cobalt (maximum). The disclosed alloy is fabricated into 11/4 or 2 inch, 32 mm or 50 mm bar stock and has a length of about 22 inches, 56 cm. This bar stock has an aperture formed therein to define a closed high temperature, high pressure oxygen chamber. The opposite and closed end of the vessel is provided with a small blind aperture into which a thermocouple can be inserted. The closed end of the vessel is inserted into an oven, preferably heated by standard nickel chrome electrical elements and having a heavily insulated exterior.

    Abstract: A process for dewaxing a mold for use in lost wax casting is proposed, wherein the mold is loaded on a pallet which is placed and then securely held on a carrier which is rotatably assembled in a dewaxing tank. The mold is inverted to be ready for dewaxing within the tank and then returned to the initial condition within the tank by rotating the carrier by about 180 degrees at a time.An autoclave for use in the process comprises a carrier framework rotatably disposed within a dewaxing tank for carrying a pallet loaded with shell mold trees. The carrier framework is held in a first position for assembling the pallet and then is rotated by about 180 degrees to a second inverted position to hold the pallet securely in the inverted condition during the dewaxing operation.A preferred embodiment of the autoclave further comprises means for securely fastening the pallet and the mold trees automatically and simultaneously with the operation of sealingly closing the entrance opening of the dewaxing tank.
