Abstract: A device for the disposal of human waste matter, specifically a toilet, is presented. This toilet incorporates elements designed to prevent both a loss of flushing efficiency and an extensive consumption of water, all while improving upon the basic functionalities of the toilet as such. These elements include specialized parts designed to both improve the efficacy of the “siphon jet” type toilet by precluding the possibility of aeration within certain critical components of the toilet system proper, as well as a specialized rim fed channel whose intersection of the filled jet channel always travels below the operating water level of the bowl, and a vacuum assisted flushing system, whose primary purpose is to enhance the power of the toilet's flushing action.

Abstract: Described is a fluid control valve for use in a urinal having a drip edge to direct fluid flow. The fluid control valve includes an outer sealing body wall surrounding a sealing area and a flexible membrane positioned within the sealing area. The flexible membrane creates a seal with the outer sealing body wall within the sealing area. The drip edge of the fluid control valve may be formed in the flexible membrane or the outer sealing body wall to direct fluid away from the fluid control valve to prevent formation of solids build-up. Additionally, the drip edge can direct fluid towards a flushing sensor to initiate a urinal flushing operation.

Abstract: A visual indicator for denoting a fluid level in a throat portion of a waterless urinal cartridge is presented. The visual indicator comprises a fluid level indicator disposed in the throat portion of the cartridge. As material buildup occurs inside the cartridge, a corresponding rise in the fluid level in the throat of the cartridge may be seen relative to the indicator, indicating when the cartridge will need replacement. The visual indicator may comprise markings that indicate the level of fluid within the throat portion, reactive materials, or an electronic reader. The fluid level indicator may also be made visible by ultraviolet radiation.

Abstract: A fluid inlet portion for a waterless urinal cartridge is presented. The fluid inlet portion comprises to fluid director comprising a non-linear surface proximate a throat portion of the cartridge formed to impart a horizontal velocity component to fluid flowing through the throat portion of the cartridge to reduce vertical turbulence within the fluid. The fluid director can be formed so that it is in fluid communication with at least part of a fluid layer within the cartridge. The non-linear surface imparts a horizontal velocity component, thereby reducing disruption of the fluid layer by fluid flowing through the throat portion of the cartridge. The fluid director may be positioned within the cartridge to impart a substantially horizontal swirling motion to fluid within the cartridge. A fluid deflector proximate the fluid director can receive fluid from the fluid deflector and for re-directing the fluid from the fluid director.

Abstract: A fluid exit portion for a splash-reducing urinal cartridge is presented. The exit portion comprises a splash reducer for causing fluid to exit the cartridge in a splash-reduced manner. The splash reducer is generally in the form of a spout with a tapered exit area for accelerating and directing the fluid. The spout may comprise converting fins to urge fluid to collect in a progressively narrower channel. When the cartridge is installed into a housing, the splash reducer ensures that fluid exiting the cartridge transitions into the housing with minimal disturbance, substantially parallel to the housing. The splash reducer is formed of a flexible material or is hinged with respect to the cartridge body to allow for easy insertion into a housing.

Abstract: Described is a fluid control valve suitable to permit only gravitationally induced flow. The valve includes an inlet section in the form of a self-supporting trough-shaped section and an outlet section. The outlet section is formed from a flexible resilient material connected to the inlet section. The outlet section includes a sealing area with side gussets that hold a set of sealing surfaces of the sealing area apart from each other, where the sealing area is connected with the inlet section at its upper edge.

Abstract: Described is a duckbill valve assembly for connecting with a waterless urinal. The assembly includes a sleeve for containing a duckbill valve therein. The duckbill valve includes a trough with two substantially parallel sheets forming a sealing area. At least one of the substantially parallel sheets includes a side pleat. When the parallel sheets separate as the valve opens, the side pleat expands, increasing the opening cross-sectional area over that afforded by the parallel sheets alone.

Abstract: Described, is a paper clip with improved performance and appearance. The paper clip comprises a lower envelope section formed from a face and a lower back part connected by a set of edges. An upper envelope section is formed from the face and an upper back part connected by a set of edges. A fold line is formed along the face. The upper envelope section is folded along the fold line such that by folding the upper envelope section along the fold line, the lower envelope section is able to receive corners of several pieces of paper. The lower envelope section is formed such that it serves as a fulcrum for the corners of the pieces of paper to be bent around to secure the pieces of paper. In a desired aspect, the paper clip is formed of paper or other sheet stock material.
