Disclosed is an indicator (15, 35) for determining the level of contents in an opaque, plastic container (10, 30, 40). The container (10, 30, 40) is filled with a solid chemical (11), such as a detergent. A spray of warm or hot water (19) impinges upon the eroding surface (16) of the solid chemical (11) to produce a chemical solution. The container (10, 30, 40) is provided with a thermo-chromatic strip (15, 35) or thermo-chromatic surface (41) for detecting the level of solid chemical (11) within the plastic capsule (10). A method of manufacturing the dispensing container (10, 30, 40) is also disclosed.

An apparatus for continuous curing (vulcanization) of elongated products, such as cables comprising a conductor surrounded by a mantle of a crosslinkable material. The cable is passed longitudinally through a curing tube in which the cable is first subjected to heating in a heating zone for heating the cable to curing temperature and subsequently subjected to cooling. The heating of the cable in the heating zone is carried out by means of heat radiation in a pressurized gas atmosphere and the cooling of the cable in the cooling zone is carried out in the presence of a gas under pressure so that heat is transferred from the heated cable in the cooling zone partially by radiation to the cooled wall of the tube and partly by convection to said cooled gas.

The invention relates to a method in connection with a process for insulating or sheathing conductors or the like, wherein plastic material is extruded into at least one layer on the surface of the conductor (1), and the conductor coated with the plastic material (2, 3, 4) is cooled in a predetermined manner. To avoid problems caused by the shrinking of the plastic material, after the cooling of the conductor (1) and the plastic material in vicinity to it to a predetermined level in the insulating or sheathing process, the surface layer of the plastic material and the plastic material portions in vicinity to it are reheated to a predetermined temperature in a pressurized space filled with a medium.
