Abstract
Abstract An apparatus is provided for collecting solids out of a waste mixture of liquid and solids flowing in a vacuum drain system. The apparatus includes a self-actuating valve means for regulating the flow of waste mixture from a reservoir which accumulates the mixture into a separator where the mixture is differentiated into its solid and liquid parts. The liquid is drawn off through a drain assembly which is attched to the vacuum drain system. The apparatus further includes an indicator to indicate when a certain quantity of solids has been collected to the separator.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
150 words
An apparatus for extracting solids from a mixture of liquid and solids flowing in a vacuum drain system, the apparatus comprising: (a) separator means for separating said solids in said mixture from said liquid; (b) drain means connected to said vacuum drain system for draining said liquid from said separator means; (c) reservoir means for accumulating said mixture; (d) aperture means for permitting said mixture to flow between said reservoir means and said separator means; and (e) valve means associated with said aperture means and disposed within said reservoir means for sensing the amount of said mixture in said reservoir means and for moving to an open position which permits said mixture to flow through said aperture means into said separator means when a predetermined amount of said mixture has accumulated in said reservoir means and to a closed position which prevents said mixture from flowing through said aperture means.
Claim 2
Independent Claim
150 words
An apparatus for extracting solids from a mixture of liquid and solids flowing in a vacuum drain system, the apparatus comprising: (a) separator means for separating said solids in said mixture from said liquid; (b) drain means connected to said vacuum drain system for draining said liquid from said separator means; (c) reservoir means for accumulating said mixture; (d) aperture means for permitting said mixture to flow between said reservoir means and said separator means; and (e) valve means associated with said aperture means and disposed within said reservoir means for sensing the amount of said mixture in said reservoir means and for moving to an open position which permits said mixture to flow through said aperture means into said separator means when a predetermined amount of said mixture has accumulated in said reservoir means and to a closed position which prevents said mixture from flowing through said aperture means.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 further including indicator means cooperating with said valve means for providing an indication when the amount of said separated solids in said separator means exceeds a predetermined quantity.
Claim 4
Dependent Claim
36 words
The apparatus of claim 2 wherein said indicator means comprises a sensor means attached to said valve means for holding said valve means in said open position when said predetermined quantity of separated solids is exceeded.
Claim 5
Dependent Claim
45 words
The apparatus of claim 1 wherein said drain means is hermetically disposed within said separator means for introducing a vacuum thereinto, said vacuum acting through said aperture means for drawing said mixture into said separator and for moving said valve means to said closed position.
Claim 6
Dependent Claim
61 words
The apparatus of claim 1 wherein said valve means comprises a float means for floating on said accumulated mixture, and a stopper means disposed on said float means adjacent said aperture means for opening said aperture means when said valve means moves to said open position and for closing said aperture means when said valve means moves to said closed position.
Claim 7
Dependent Claim
33 words
The apparatus of claim 5 further including indicator means cooperating with said stopper means for providing an indication when the amount of said separated solids in said separator means exceeds a predetermined quantity.
Claim 8
Dependent Claim
30 words
The apparatus of claim 6 wherein said sensor means comprises a rod in fixed spatial relationship with said stopper means and extending through said aperture means into said separator means.
Claim 9
Dependent Claim
23 words
The apparatus of claim 1 further comprising strainer means adjacent said aperture means for preventing the passage of relatively large solid particles therethrough.
Claim 10
Independent Claim
139 words
An apparatus for separating a mixture of solids and liquids in a vacuum drain system, said drain system having a vacuum introduced thereinto, said apparatus comprising: (a) separator means for separating said solids in said mixture from said liquid; (b) reservoir means for accumulating said mixture, said reservoir means including aperture means for permitting said mixture to flow between said reservoir means and said separator means; and (c) valve means disposed within said reservoir means and responsive to the amount of mixture accumulated therein for moving to an open position when said mixture accumulation exceeds a predetermined amount, said open position permitting said mixture to flow through said aperture means, and for moving to a closed position when said mixture accumulation is less than said predetermined amount, said closed position preventing said mixture from flowing through said aperture means.
Claim 11
Independent Claim
139 words
An apparatus for separating a mixture of solids and liquids in a vacuum drain system, said drain system having a vacuum introduced thereinto, said apparatus comprising: (a) separator means for separating said solids in said mixture from said liquid; (b) reservoir means for accumulating said mixture, said reservoir means including aperture means for permitting said mixture to flow between said reservoir means and said separator means; and (c) valve means disposed within said reservoir means and responsive to the amount of mixture accumulated therein for moving to an open position when said mixture accumulation exceeds a predetermined amount, said open position permitting said mixture to flow through said aperture means, and for moving to a closed position when said mixture accumulation is less than said predetermined amount, said closed position preventing said mixture from flowing through said aperture means.
Claim 12
Dependent Claim
30 words
The apparatus of claim 9 wherein the valve means comprises: (a) a float disposed within said reservoir means; and (b) a stopper disposed on said float adjacent said aperture means.
Claim 13
Dependent Claim
26 words
The apparatus of claim 9 wherein said separator means further includes drain means coupled to said drain system for draining said liquid from said separator means.
Claim 14
Dependent Claim
33 words
The apparatus of claim 11 wherein said vacuum is introduced into said apparatus through said drain means and said valve means is moved to said closed position by a force comprising said vacuum.
Claim 15
Dependent Claim
24 words
The apparatus of claim 9 further including indicator means for providing an indication when the amount of said separated solids exceeds a predetermined quantity.
Claim 16
Dependent Claim
22 words
The apparatus of claim 9 further including means adjacent said aperture means for preventing the passage of relatively large solid particles therethrough.
