Abstract: An improved bottle assembly consisting of a container 1100, a vent unit 1200, a nipple 1300, and collar 1400, wherein the vent unit 1200 geometry allows air to enter the assembly to prevent development of a partial vacuum, yet will not allow liquid to escape through said vent unit when assembly is rotated into a horizontal or inverted position during use.

Abstract: An improved toilet assembly incorporating a supply water passage 400 and supply water mechanical assembly 500 into the design to provide means to deliver a pressurized jet of water to remove clogs. This jet is actuated via an independent flush valve 506, fed directly from the pressurized water supply, and located within a drain passage 300.

Abstract: An improved toggle bolt assembly consisting of a toggle nut 100, collar 200, and screw 300, wherein the toggle nut 100 consists of an internally threaded cylindrical sleeve 110, a first winged member 120, and a second winged member 130. The cylindrical sleeve 110 of the toggle nut 100 engages with a collar 200, acting to center the assembly, hold the toggle nut 100 and collar 200 in place without engagement of the screw 300, and eliminate the need to apply tension to the screw 300 during installation.

Abstract: A masking material which incorporates a liquid-repellent component 407 for use as masking tape and masking sheet is herein disclosed. A masking material according to the present invention comprises a base material 401 having a top surface 402, a bottom surface 403, and at least one masking edge 404. The bottom surface 403 of the base material 401 has an adhesive layer 406 applied thereto. A liquid-repellent component 407 comprises at least the top surface of the one masking edge 404 of the base material 401 so as to at least substantially prevent liquids applied to the liquid-repellent component 407 from forming a continuous liquid layer between the top surface 402 of the base material 401 and the adjacent surface to which the liquid was applied 508.
