Abstract
Abstract An improved waterless toilet for aerobic biological transformation of organic waste material is disclosed. The toilet is located at a position remote from a compartment wherein waste material is aerobically transformed. The toilet is connected to the compartment by a conduit. Organic waste is deposited into the toilet and a subsequently applied vacuum aids in the transporting of the waste material through the conduit to the compartment. Prior to depositing organic waste material into the toilet, a cup-shaped paper wrapping means is inserted into the toilet. Thereafter the vacuum is applied to the paper wrapping means and waste material to cause the paper wrapping to close around the waste material as it enters the conduit. Utilizing paper wrapping means, the toilet is protected from soiling by the organic waste material when it is deposited in the toilet. Furthermore, the paper wrapping means protects the conduit from soiling, it acts to clean the interior of the conduit by a wiping action during transport of the wrapper and its included organic waste material through the conduit to the compost compartment.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
266 words
An apparatus for aerobic biological transformation of human waste material comprising: (a) an aerobic composting compartment for holding said waste during aerobic biological transformation, said compartment having upper inlet and upper outlet means; (b) a waterless toilet adapted to receive deposited human waste; (c) a cup-shaped paper receptacle, associated with said waterless toilet, having a cup portion and a cone portion, said cup portion being fabricated from a limited water absorbing material and said cone portion being fabricated from a water absorbing material, means for inserting said cup-shaped receptacle into said waterless toilet prior to depositing said human waste, said cup portion containing said human waste; (d) a first conduit, coupling said waterless toilet to said composting compartment inlet means, for transporting said cup-shaped paper receptacle containing said human waste from said toilet to said composting compartment, said cone portion wiping said first conduit interior clean as it traverses through said conduit; (e) vacuum generating means, associated with said first conduit means, for creating a vacuum within said first conduit means thereby transporting said cup-shaped paper receptacle from said toilet to said composting compartment; (f) funnel means communicating with said first conduit for injecting decomposable garbage, cut grass, weeds, leaves and the like into said composting compartment thereby facilitating the decomposition of said human waste; and (g) an exhaust conduit, connected to said composting compartment outlet means, for exhausting air and water vapor from said composting compartment; and (h) a water vapor separator, associated with said exhaust conduit, for preventing condensed water vapor running back down the interior of said exhaust conduit into said composting compartment.

Claim 3
Dependent Claim
14 words
The apparatus of claim 1 wherein said cup portion includes a flat head portion.
Claim 4
Dependent Claim
15 words
The apparatus of claim 1 wherein said cup portion includes a conical shaped head portion.
Claim 5
Dependent Claim
51 words
The apparatus of claim 1 wherein said water vapor separator includes (a) a perforated conical member circumfentially abutting the interior of said exhaust conduit; and (b) a second conduit, disposed adjacent the top surface of said conical member, for draining the condensed water to a point remote from said exhaust conduit.
