Appl. No.:

13/562308

Inventors:

James T. Han - Rockville MD, US

International Classification:

E03D 5/00

US Classification:

4405, 4324, 4415, 4412

Abstract:

A dual flush device is disclosed to provide a full flush for removing solid waste and a water-saving partial flush for removing liquid or light solid waste in a toilet. It includes a first flush handle attached to a shaft to raise a lever to open a flapper valve, and a second flush handle that overlaps the first handle and opens the flapper valve through the first handle. A float assembly is disclosed to be used either with the dual flush device or with the original single flush lever assembly to prematurely close an opened flapper valve and reduce water consumption. Using the original flapper valve in a conventional toilet tank, a dual flush function is achieved by any of the three implementation choices: (1) the dual flush device alone; (2) the dual flush device and a float assembly; and (3) a float assembly alone.

Abstract:

A dual flush device comprises a mounting structure and a float to retrofit single flush toilets to dual flush toilets. The mounting structure is attached to an overflow tube and connected to the float with a vertical bar along which the float can move vertically downward or upward with the water level in the toilet tank. The float includes a water-tight container and a bottom part screwed into the bottom of the container. The vertical length of the float is adjustable by rotating the bottom part either away or toward the container. Several embodiments of the mounting structure and float are invented to accommodate various toilet models. The dual flush device operates with a flapper valve and a single flush handle assembly and maintains the modular design of conventional toilets. The float will prematurely close the flapper valve in a partial flush using less water than in a full flush.

Abstract:

Disclosed are various embodiments for maintaining an interconnected network of platforms via a securities offering application. The interconnected network of platforms may comprise a master platform and at least one sub-platform. Each platform may be used to access or facilitate an offering for a plurality of securities over a network, thereby allowing issuing entities to raise capital. A first investment organization may syndicate a deal to a second investment organization. The securities offering application may further maintain a plurality of collaboration components accessible by the users to communicate across the interconnected network of platforms.
