  • Patent number: 6039368
    Abstract: A readily cleanable litter cleaning system for removing fecal matter from a litter box includes a container having substantially identical front and rear panels joined by substantially identical side panels and a bottom panel. The container has a rectangular cross-section defining an open top and a liquid storage region. The container has a predetermined width along the front and rear panels and a predetermined depth along the side panels. The container includes at least one projection extending from at least one of the panels into the liquid storage region. The projection terminates in an end in spaced relation from the bottom panel. A top cover is tightly fitted to the container and seals the container open top. The cover defines an opening therein. A scoop for removing the fecal matter from the litter has a blade portion and an elongated handle. The blade portion has a width configured for placement in the container generally parallel to the front and rear panels and for fitting between the side panels.

  • Patent number: 6013885
    Abstract: An electric switch housing comprises a generally downwardly open rectangular dielectric casing which has laterally spaced side walls and opposed end walls integrally connected at their adjacent vertical edges to form four corners. The casing has a top wall, which includes a raised center rib portion having laterally spaced sockets, and is integrally joined with the top edges of the side and end walls. The casing defines an integrally formed upwardly open cavity for receiving an actuator. The actuator has upper shoulder portions received in the laterally spaced sockets, and is pivotally received in the casing. A generally upwardly open rectangular dielectric base is received in the downwardly open casing, defining a switch cavity containing at least two terminals and at least one movable switch contact in the base. A lamp module is provided in the casing and is supported between the base and the casing.
