Abstract: The invention relates to an applicator device (2) and a method of application which allows one or more adhesive tapes to be applied to a surface, with the tape or tapes being applied at a known offset distance (x) from at least one datum. This ensures that the tape can be applied at the required location to allow further work, such as the application of a sealant to be achieved accurately and neatly in a gap formed between the lengths of tapes. In one embodiment the device (2) has at least one, but typically both side wall portions (14,16) which can be adjusted with regard to the body (4) of the device to allow the offset distance (x) of the tape from a datum to be selectable.

Abstract: A process for manufacturing a sliding plate for a valve closure on metallurgical melt containers may include forming the sliding plate by: integrating in a pressing procedure with a press, a pre-pressed annular insert made of a refractory ceramic material in a base body made of a refractory ceramic material; and removing the sliding plate from the press, resulting in an annular gap between a circumferential surface of the insert and a corresponding surface of the base body. The process may also include impregnating a transition area including the annular gap between the insert and the base body with an impregnation agent, and tempering the plate at temperatures between 200° C. and 700° C. to cause the impregnation agent to create a non-positive direct connection between the base body and the insert.
