  • Method of producing flat slide valves
    Patent number: 5975103
    Abstract: The invention relates to a method of producing a flat slide valve with incorporation of at least one inlet disk in a housing or in at least one element of a housing, wherein the inlet disk is joined to the housing or to at least one element of the housing by forcelocking, formlocking and/or bonding. The invention further provides a flat slide valve having at least one sealing disk, in which at least one of the sealing disks is incorporated into an element of the flat slide valve.

  • Ceramic articles, and a process for the production thereof
    Patent number: 5070658
    Abstract: A ceramic sealing component for a machine which is in frictional contact and has at least one non-reflective sliding and sealing face of a mean roughness (Ra) greater than 0.1 and a minimum of 0.8 .mu.m is described. A component of this type can be produced by subjecting a green ceramic article to shaping, sintering, processing by face-grinding or round-grounding, optionally washing and then abrasive-polishing in the presence of an aqueous phase until the mean roughness desired for the machine component is reached.
