Abstract: A connector assembly for detachably securing a toilet seat to a toilet bowl includes a base plate which is fixedly securable to the seat and has at least one bore. A clamping unit passes through the bore for detachably securing the base plate to the bowl and includes one end which projects beyond the base plate and another end which is insertable in an aligned mounting hole of the bowl. A lever connects the one end of the clamping unit for volumetrically increasing the clamping means in radial direction within said mounting hole to attain a secure attachment of said base plate to the bowl.

Abstract: A connector rotatably joining the toilet seat/cover permits rapid attachment to a toilet bowl without the use of tools and without leaving securing members on the toilet bowl, whereby the closing of clamping components in the existing, seat mounting holes in the toilet bowl and atmospheric pressure by means of suction cups holds the toilet seat/cover to the edge of the toilet bowl.

Abstract: An apparatus for liquefying meltable material comprises a container adapted to be filled with the material to be liquefied. The container has a heavy bottom wall formed with closely adjacent perforations which taper in downward direction. The sum of the open cross-section of the perforations at the upper face of the bottom wall is only slightly smaller than the total area of the latter, whereas the sum of the smallest cross-sections of the perforations is only a small fraction of the total area of the bottom face of the bottom wall. The bottom wall is heated by electrical heating elements located in ribs separating the perforations from each other to a temperature to liquefy the material passing from the container into the perforations and the liquefied material flows in a collecting trough arranged below the container and separated by a heat insulating layer therefrom.
