Abstract
Abstract Pharmaceutically useful trace elements contained in human urine are collected by disposing a filter body containing an adsorbent for the trace elements in the gravity flow line connecting the unflushed urinal of a portable toilet to its holding tank. The portable toilet also includes a seat connected to the holding tank by a separate gravity feed line. The holding tank contains an odor reducing chemical solution for the urine and fesces. A filter body supported in the conduit between the urinal and the holding tank consists of an adsorbent for the trace constituents of the urine that it is desired to extract. Urine voided into the urinal passes through the adsorbent filter body before going to the holding tank. When the holding tank of the portable toilet is pumped clean and the deoderizing solution replaced, the filter body is removed and processed to extract the trace constituents replaced with an unsaturated filter body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
In a flushless toilet of the type having a urinal, a holding tank containing an odor preventing chemical solution, and a gravity flow conduit connecting the urinal to the holding tank, a filter body containing an adsorbent for at least certain trace constituents of urine removably supported in the conduit intermediate the urinal and the holding tank so that urine flowing from the urinal to the holding tank contacts the adsorbent allowing urine voided into the urinal to pass through the conduit and the filter body to the holding tank under the force of gravity, the urine thereby contacting the adsorbent so that at least a portion of the trace constituents adhere to the adsorbent from which they may be extracted upon removal of the filter body from the toilet.
Claim 2
Dependent Claim
130 words
In a flushless toilet of the type having a urinal, a holding tank containing an odor preventing chemical solution, and a gravity flow conduit connecting the urinal to the holding tank, a filter body containing an adsorbent for at least certain trace constituents of urine removably supported in the conduit intermediate the urinal and the holding tank so that urine flowing from the urinal to the holding tank contacts the adsorbent allowing urine voided into the urinal to pass through the conduit and the filter body to the holding tank under the force of gravity, the urine thereby contacting the adsorbent so that at least a portion of the trace constituents adhere to the adsorbent from which they may be extracted upon removal of the filter body from the toilet.
Claim 3
Dependent Claim
19 words
The toilet of claim 1 further including a separate toilet seat having its output connected to the holding tank.
Claim 4
Dependent Claim
24 words
The toilet of claim 1 including a unitary supporting and enclosing structure for the urinal and the holding tank, said structure including a door.
Claim 5
Dependent Claim
13 words
The toilet of claim 1 wherein the adsorbent constitutes an ion exchange resin.
Claim 6
Dependent Claim
29 words
The toilet of claim 1 further including means supported in the conduit between the urinal and the adsorbent filter for controlling the pH of urine passing through the filter.
Claim 7
Dependent Claim
172 words
A flushless portable toilet incorporating means for extracting commercially useful constituents from the urine voided into the toilet comprising: a unitary enclosed shelter having a door; a urinal supported within said shelter; a holding tank supported in said shelter at a level below the urinal, said holding tank being adapted to retain a deoderizing chemical solution for the urine; a conduit connecting the urinal to the holding tank; container means formed as part of the conduit intermediate the urinal and the holding tank for retaining a filter body; and a filter body removably disposed in the container means, the filter body constituting an adsorbent for at least certain trace constituents of urine allowing urine voided into the urinal to pass through the conduit and the filter body to the holding tank under the force of gravity, the urine thereby contacting the adsorbent so that at least a portion of the trace constituents adhere to the adsorbent from which they may be extracted upon removal of the filter body from said container means.
Claim 8
Dependent Claim
172 words
A flushless portable toilet incorporating means for extracting commercially useful constituents from the urine voided into the toilet comprising: a unitary enclosed shelter having a door; a urinal supported within said shelter; a holding tank supported in said shelter at a level below the urinal, said holding tank being adapted to retain a deoderizing chemical solution for the urine; a conduit connecting the urinal to the holding tank; container means formed as part of the conduit intermediate the urinal and the holding tank for retaining a filter body; and a filter body removably disposed in the container means, the filter body constituting an adsorbent for at least certain trace constituents of urine allowing urine voided into the urinal to pass through the conduit and the filter body to the holding tank under the force of gravity, the urine thereby contacting the adsorbent so that at least a portion of the trace constituents adhere to the adsorbent from which they may be extracted upon removal of the filter body from said container means.
Claim 9
Dependent Claim
26 words
The portable toilet of claim 6 further including a toilet seat disposed within the shelter and connected to the holding tank by a gravity feed pipe.
Claim 10
Dependent Claim
36 words
The portable toilet of claim 6 further including means disposed in the conduit between the urinal and the container means for the filter body for adjusting the pH of the urine flowing through the filter body.
