    摘要: The filter devices allow easy cleaning of various joint portions such as those located near changeover valves of the filter devices. Heating units which accommodate filter cases may be formed with openings which allow such joint portions between the filter cases and the heating units to be accessed and cleaned. Alternatively, the heating units may include two relatively movable parts which, when opened, allow the joint portions to be accessed once the filter cases are removed. The heating units themselves may be detachable from a support frame so as to expose other joint portions.

    摘要: An improvement in a process for producing an elastic polyester wherein a crystalline aromatic polyester and one or plurality of lactones are reacted, the improvement comprises by carrying out the reaction in a continuous process by continuously feeding the molten crystalline aromatic polyester and the lactones to a reaction vessel to subject them to addition polymerization, while continuously discharging a reaction mixture from the vessel to obtain the elastic polyester. Optionally, the reaction mixture can be further subjected to polycondensation in a molten state or a solid phase.

    摘要: An austenitic stainless steel valve which is used at 100.degree. C. or higher is easy to operate at the beginning of use. The valve of the present invention has a valve body made from an austenitic stainless steel, and a stem adapted to be reciprocated to open and close the valve. The stem is made from a metal having a thermal expansion coefficient that is ten-thirteenths or less of that of an austenitic stainless steel. Such a metal may be a ferritic or martensitic stainless steel. With this arrangement, it is possible to restrict the compressive stress applied to the stem within an allowable stress for the material of the stem and thus to prevent the destruction of the seat or the bending of the stem. The valve can thus be used easily.

    摘要: A filter housing includes a filter body having an opening, and a lid detachably mounted on the body to close the opening of the body. The lid is provided with a jacket in which is sealed a vapor-liquid two-phase heating medium. An electromagnetic induction heating mechanism having an induction coil is provided to heat the heating medium to vaporize it and heat the lid with the vaporized heating medium. The heating mechanism is fixedly mounted on the filter body so that only the lid needs to be detached from the body when exchanging a filter element.
