Waste disposal system

Claim 2

The waste disposal system set forth in claim 2, wherein said inner container is vertically positioned in said storage tank, and wherein said first conduit conveys waste products into the bottom of said inner container while said drain conduit receives liquid effluent from the top of said inner container.

Claim 3

The waste disposal system set forth in claim 2, wherein said inner container is self-supporting within said storage tank and has compressible sidewalls.

Claim 4

The waste disposal system set forth in claim 2, wherein said inner container is flexible and nonself-supporting and wherein said storage tank includes a retainer for supporting said inner container.

Claim 5

A self-contained, noncontaminating waste disposal system comprising: a toilet for receiving human waste matter and flushing fluids; a storage tank having an inner, impervious, removable, compressible container for receiving waste products, and an outer container enveloping said inner container and forming a chamber therebetween, and wherein said outer container includes a flexible portion; a conduit connected to said toilet and storage tank for conveying waste products into said inner container; vacuum drawing means connected into said chamber between said containers for withdrawing air therefrom to cause said flexible portion of said outer container to collapse upon and compress the inner container and thereby effect removal of liquid effluent from said inner container; a drain conduit connected to said storage tank for removal of liquid effluent from said compressed inner container; pasteurizing means operatively connected to said drain conduit for heating liquid effluent therein to a temperature of at least 160* F.; and control means connected to said vacuum drawing means and said pasteurizing means for allowing air to be drawn from said chamber only when said pasteurizer is at a temperature sufficient to pasteurize liquid effluent so that only harmless pasteurized liquid is discharged from the system; and wherein said inner container is removable from said storage tank to dispose of the retained solid waste products.

Claim 6

A self-contained, noncontaminating waste disposal system for passenger-carrying vehicles driven by an engine with an air intake system comprising: a toilet for receiving human waste matter and flushing fluid; a storage tank having an inner impervious, compressible, removal inner container for receiving the waste products from said toilet, and an outer container enveloping said inner conTainer and forming therewith a chamber therebetween, and wherein said outer container has a flexible portion; a conduit connected to said toilet and said storage tank for conveying waste products from said toilet into said container; a drain conduit connected to said inner container with a filter positioned therein through which only liquid effluent flows to the engine for pasteurizing liquid effluent in said drain conduit; a vacuum line connected to said chamber between said containers and to the air intake of the engine for drawing air from said chamber to effect a pressure differential across said flexible portion of said outer container to cause it to collapse upon and compress said inner container whereupon liquid effluent flows through the filter and through the drain conduit where it is pasteurized by the engine; and control means connected to said vacuum line for allowing air to be drawn from said chamber whenever said engine is at a temperature sufficient to pasteurize liquid effluent so that only harmless, pasteurized liquid effluent is continuously discharged therefrom.

Claim 7

The self-contained, noncontaminating waste disposal system set forth in claim 7, wherein a signal means connected to said storage tank is provided which indicates when said inner container is filled.

Claim 8

The self-contained, noncontaminating waste disposal system set forth in claim 8, wherein the control means includes a thermooperated valve connected in said vacuum line.

Claim 9

The self-contained, noncontaminating waste disposal system set forth in claim 9, wherein the control means also includes a backfire trap connected in the vacuum line to the engine backfire from flowing into the storage tank, and a normally open one-way valve which permits vacuum to be drawn but which prevents raw fumes from the engine from flowing back into said storage tank.

Claim 10

The self-contained, noncontaminating waste disposal system set forth in claim 8, wherein said drain conduit enters and leaves the rear portion of said engine manifold and is U-shaped in passing therethrough.

Claim 11

The self-contained, noncontaminating waste disposal system set forth in claim 7, wherein said engine is water cooled and includes a thermostat to maintain the cooling water at a temperature of at least 160* F., and wherein said drain conduit is connected to the intake of said engine-cooling system.

Claim 12

The self-contained, noncontaminating waste disposal system set forth in claim 8, wherein said inner container is vertically positioned in said storage tank, and wherein said first conduit is connected into the bottom of said inner container while said drain conduit is connected into the top thereof.

Claim 13

The self-contained, noncontaminating waste disposal system set forth in claim 10 for marine craft, wherein the system includes another conduit having a normally closed valve connected to said inner container and a deck pump fitting aboard the craft, and a still further conduit also connected to said inner container having a normally closed valve and extending through the hull of the craft.
