Abstract: The present invention relates to a method for controlling the thickness of an intermetallic layer (Fe-Zn phase) on a steel strip in a continuous hot-dip galvanizing line. The steel strip is rapidly cooled by quenching in a zinc bath and the structure of the coating to be formed on the steel strip is controlled by directing a flow of molten zinc, cooled to a temperature 1 DEG  to 15 DEG  C. below the operating temperature of the zinc bath, towards the steel strip. At least a part of said flow is preferably directed towards the steel strip close to its immersion point into the zinc bath, obliquely against the movement direction of the steel strip.

Abstract: The present invention relates to a machine for the production of vulcanized rubber tubing. The machine comprises a pair of opposite heads (2,3) provided with mandrels (4,5), which rotate at least one tubular core (6,7) supported by first roller-fitted resting elements which are fixed on a supporting frame (11). The line of the rollers, and therefore the tubular core, is flanked by an openable thermally insulated box-like container (19) adapted to contain the core itself, wrapped by the tubing to be vulcanized and unloaded by transfer means coupled to the frame (11). The heads of the box-like container (19) have electric terminals for supplying power to the core (6,7) and heating it by means of the Joule effect. Removal means move the core from the container onto second retractable roller-fitted resting elements which are articulated to the frame for extracting the core from the vulcanized tubing by injecting air.

Abstract: An electrode for engraving electric spark machining which is produced by using a mixture of gypsum hemihydrate powder serving as both a principal material and a binder with a conductive metal powder as a filler, transferring, shaping and hardening the mixture into a desired shape to form electrode material and plating the electrode with the conductive metal. Gypsum hemihydrate powder, gypsum dihydrate powder of less than 1 vol % on the basis of the former and the conductive metal powder are kneaded in a vacuum. Water is added to the kneaded matter, which is again kneaded in a vacuum, poured into a mold to which a predetermined shape is transferred, shaped and hardened by hydration to obtain an electrode material. Then the electrode material is dried and plated with the conductive metal so as to reinforce electrical connection with the metal powder. Since the electrode is made of gypsum as the principal material, even an electrode for electric spark machining to which a precise and complicated shape is transferred can be produced easily, economically, and precisely by the use of a simple mold of, e.g. a silicone rubber, and hence it is particularly suitable for producing dental crowns one by one. Furthermore, gypsum hemihydrate as the principal body of the electrode material and the conductive metal film increase the strength of the electrode by virtue of their synergistic effect. The present invention makes possible machining of a hard material such as titanium for which precise electric spark machining at a desired speed has been difficult by the use of a conventional electrode subjected to impregnation treatment of a conductive solution in which graphite or the like is dispersed in place of plating treatment.

Abstract: The fitting with the hose shower comprises a fitting housing at which there is arranged a laterally actuatable control cartridge. Downstream of the control cartridge, viewed with respect to the direction of water flow, there is provided a safety device arranged above the control cartridge. Under normal operating conditions, water flows from the control cartridge via the safety device to an outlet. Under conditions rendering possible a backflow, a backflow preventer of the safety device cuts off the flow path of water and a pipe aerator connects the outflow line or conduit via an aeration path with the environment. As a result, there is precluded a backflow of water into the supply or feed line.
