Inventor: HOLZGRUBER WOLFGANG DR
IPC: C22B9/18
Filed: 1995-02-20
Abstract: Metal blocks, in particular, those of steel and alloys on nickel and cobalt basis, are produced by melting of self-consuming electrodes under an electrically conductive slag in an atmosphere of controlled composition. Melting of the electrode takes place in a gas-tight space bounded by the slag bath surface, the wall of a mould (20), and a mould hood (24). Electrode change takes place by removing the hood (24) from the mould and replacing it with another hood (24a). The electrode rod (26) has a gas-tight fit with the hood opening (28).

Patent DE-19604131-A1 (DE)
Inventor: HURTZ WINFRIED
IPC: A44B17/00
Filed: 1996-02-06
Abstract: The invention relates to a lockable snap fastener in which the male component is secured, after engaging in a housing of the female component, by the locking profile of a slide. The slide can be slid in the housing of the female component transversely to the direction of insertion of the male component and is held in a withdrawn position by a spring portion provided at its inner end. The locking profile of the slide is then placed onto the male component in its active position. However, the slide has also a release profile which enters in the area of the engaged male component and allows disengagement while the slide is being operated. To obtain an easily operable snap fastener, it is proposed to position two slides adjacent each other in the housing of the female component and to spring-load said slides to oppose each other in the direction of withdrawal. The locking profile and the release profile are realized in the joint area between the two slides partially in one slide and partially in the other slide. Consequently, snap-on engagement of the two snap fastener components is possible without operating the two slides.
