Abstract: An improved toilet seat closure is described employing weight-driven cords or cables for pivoting forward and lowering a toilet seat and its lid without a loud noise upon flushing of the toilet. The seat and mechanism for achieving the automatic closing can be easily retrofitted to existing toilets without any unsightly or major modification of the toilet or tank. The mechanism employs a flexible cable or cord which runs through a tubular sleeve and extends under and behind the tank and over the rear lip of the tank so as to be substantially out of sight to the users. The cord or cable is connected to a weight in the tank (which weight has a specific gravity slightly higher than 1) so that on flushing the weight draws down the cord or cable a short distance. The cord also runs over a fixed pulley and runs free to the end of a pivoting arm extension from the seat member.

Abstract: A trailer especially useful for transporting and unloading bulk powdered material that tends to clump or clod under slight compacting is disclosed, which trailer includes a generally enclosed compartment for holding the bulk material, an air vent at an upward part of the compartment, and has a bottom floor to the compartment equipped with means for injecting air under pressure, which air travels through the material and exits at the vent and serves to mobilize and fluidize the powdered material in the compartment and allows it to flow by gravity down the floor toward an exit wherein it is removed. The particular trailer disclosed is converted from a conventional rectilinear combination or box trailer by the addition of a double set of pipes in the floor, which pipes are supplied during unloading with air from outside the trailer while the trailer is tilted upward on its rear wheels to slant its floor toward the rear wherein an exit manifold is provided for pumping out the fluidized bulk material.
