Abstract: In the device, it can be detected as quickly as possible and without difficulties whether a battery fault has occurred. A testing generator which cyclically blanks out the trickle charge of the batteries so that the supply of the appliance or the installation has to be taken over by the battery is combined with a flip-flop circuit which keeps the control logic in an "off state" if the voltage drops below a predetermined limit value. In an advantageous embodiment, the control logic of the appliance, but not the load, is supplied from the battery during the blanking out process. <IMAGE>

Abstract: This invention relates to apparatus for dispensing wrapping material such as cling film from a roll (37) of such material. The material to be dispensed is guided along a path defined by two rollers (35 and 47) between which is arranged a toothed perforating blade (49). The blade is pivotally mounted and biased into a position in which the teeth just protrude into said path and engage the material (48) to be dispensed. When the material is moved along the path, it rotates the perforating blade into a position in which the teeth protrude further into the path, thus perforating the material. Continued movement of the material causes continued rotation of the blade until the teeth are withdrawn from the path (49b). The apparatus also includes a severing device (44) to enable sheets of material to be removed at the perforations.

Abstract: The invention contemplates horizontal continuous casting of steel strands (10) using a relatively short water-cooled horizontal mold passage (13) from which there is continuously and horizontally withdrawn an embryo casting having a solidified outer shell (25) surrounding a molten metal core (26). To assure continuous flow of molten steel to the cooled mold, a supply passage (18) is provided of refractory material impervious to liquid steel. This supply passage (18) is so formed that there is such a drop (H) in elevation between entrance and exit as will enable a head of ferrostatic pressure to exist, to maintain a condition of peripherally continuous pressure contact with the cooled mold (13). i.e. intensified cooling of the casting shell formed in the mold. Immediate water-cooling of the existing embryo casting assures against such reheating of the shell (after it leaves the mold) as might otherwise give rise to bulging or other deformation of the casting.

Abstract: A boiling/cooling system for cooling a semiconductor element in use thereof has at least one cooling member (5) including an evaporating section (5a) containing a liquid refrigerant of high vaporizability sealed in it and a condensing section (5d) for cooling the liquid refrigerant from the evaporating section when it is heated and vaporized. The semiconductor element is clamped to the evaporating section. To avoid problems arising from the application of a high voltage to the cooling member, a highly thermally conductive insulating material (4) is interposed between the semiconductor element (1) and the evaporating section (5a) and clamped into position by a metal clamp (10). The evaporating and condensing sections can thus be in a unitary structure.
