  • Rotation lock mechanism for aircraft seat
    Patent number: 6938957
    Abstract: A braking mechanism to control rotational movement of a seat is disclosed. The braking mechanism may comprise a circular member (e.g., a disc or ring) that is coupled to a base assembly and a caliper, coupled to a seat assembly, to engage the circular member. In a biased position, a braking element of the caliper applies a braking force to the circular member. A user can reduce the braking force by increasing the tension on a cable coupled to the caliper. Once the braking force is sufficiently reduced, the user may rotate the seat until the desired rotational orientation is attained. Upon release of the cable, the braking mechanism re-engages to prevent further rotational movement.

  • Washbasin drain assembly
    Patent number: 6023795
    Abstract: A washbasin drain assembly comprises a drain body which defines a drain passage connecting the interior space of the washbasin to the waste line and a drain plug in cooperative engagement with the drain body for selectively sealing the drain passage. A sieve is fitted removably in the drain body downstream of the plug relative to the direction of flow from the basin to the waste line.
