Abstract: A temperature sensor for radiant heating units with a heating coil disposed in a cup includes a tube with a first end connected to a housing of a switch with a movable contact cooperating with stationery contacts in the housing. A two-section rod, which extends into the housing of the switch and operates the movable contact, is supported inside the tube. The tube and the rod have different thermal expansion coefficients. To prevent a shift in the switching point, the section of the rod that operates the contact terminates outside the hollow space of the cup, and the temperature-induced length changes of this section and of the housing are matched to each other.

Abstract: A process for making a metal-matrix composite (MMC), includes a mixture of particulate ceramic powder with a liquid carrier, without addition of a binder, to prepare a slip having thixotropic properties. The slip is introduced in a substantially dense consistency into a casting mold which is then subjected to vibrations so as to separate the carrier from the ceramic particles and to allow the carrier to float upon the ceramic particles while at the same time compacting the slip to realize a ceramic preform of porous consistency having pores. After terminating the exposure of the casting mold to vibrations, the liquid carrier is removed and the preform is allowed to solidify in the casting mold, without exposure to any further compaction measures, such as sintering, pressing or the like, and the casting mold is maintained in a position of rest. Subsequently, matrix metal is poured into the casting mold to fill the pores of the preform.

Abstract: A temperature limiter includes a switch head with a switching contact and a temperature sensor having elongate expansion elements of different thermal expansion coefficients. The expansion elements are fixed relative to one another in one end zone and movable relative to one another in the other end zone. Slidably supported in the switch head is a ram which abuts against the movable expansion element and has an end portion constructed to allow application of welding or soldering. A switch sleeve is placed over the ram end portion and adapted to actuate the contact. The switch sleeve is movable relative to the ram during a calibration phase, until reaching a position which is determinative for calibrating a desired response temperature of the switching contact. In this position, the switch sleeve is then securely fixed to the end portion by fusion welding or soldering.
