  • Pair of ceramic disks for a mixer faucet and mixer faucet comprising same
    Patent number: 5232022
    Abstract: A pair of ceramic disks for mixer faucets includes a fixed disk and a smaller mobile disk adapted to slide on the fixed disk within given limits. The fixed disk has on one side a bearing surface adapted to lie against the mobile disk and has two feed openings and one outlet opening through it. The bearing surface of the fixed disk has a closed main rim around the three openings and at least one depression in the surface through only part of the thickness of the fixed disk. In any position of the mobile disk relative to the fixed disk, the bearing surface of the mobile disk bears on the rim all around the depression. The bearing surface further includes an inner rim which in the closed position of the mobile disk isolates the outlet opening from the feed openings.

  • Lapping machine and non-constant pitch grooved bed therefor
    Patent number: 5131190
    Abstract: A lapping machine having a lapping bed adapted to rotate about a main axis and having an annular lapping surface delimited by an inner circle and an outer circle and into which is cut a spiral groove. Virtually all of at least one confinement ring faces the annular surface and rotates about a fixed axis parallel to the main axis, contains parts to be lapped, and confines movement thereof against the lapping surface. An application disk coaxial with the ring presses the parts in the axial direction agains the lapping surface. The pitch of the groove is not constant whereby between the inner and outer circles, and excluding the inner and outer circles, there is a constant ratio between the pitch ratio .lambda.
