Abstract
Abstract A process for conveying and incinerating waste material which comprises subjecting the waste to pneumatic pressure so as to convey it through a connecting pipe to an incinerator and an apparatus directed thereto which comprises means for receiving the waste; a pneumatic ejector situated beneath the receiving means, which is a generally cylindrical vessel terminating in a conical bottom section, having an inlet valve suitable for closing off the inlet to make the vessel airtight, and an air inlet for admitting compressed air to the ejector, the air inlet being connected by a pressure air line to a control panel which, in turn, is connected to a source of compressed air; and a discharge pipe leading from the bottom of the ejector to an incinerator and connected thereto by means of a flared adapter.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A process of conveying and incinerating waste which comprises the steps of: (1) collecting the waste in a pneumatic ejector in the form of a compacted slug; (2) subjecting the compacted waste to sufficient air pressure so as to overcome the force represented by the mass of the waste and forcibly eject it into and convey it through a discharge pipe leading to an incinerator, said waste being substantially retained in its compacted state during said ejection and conveyance; (3) spreading the waste charge as it enters the incineration zone; and (4) reducing the waste to ash and/or carbon.
Claim 2
Dependent Claim
99 words
A process of conveying and incinerating waste which comprises the steps of: (1) collecting the waste in a pneumatic ejector in the form of a compacted slug; (2) subjecting the compacted waste to sufficient air pressure so as to overcome the force represented by the mass of the waste and forcibly eject it into and convey it through a discharge pipe leading to an incinerator, said waste being substantially retained in its compacted state during said ejection and conveyance; (3) spreading the waste charge as it enters the incineration zone; and (4) reducing the waste to ash and/or carbon.
Claim 3
Dependent Claim
23 words
The process of claim 1, wherein said air pressure applied to said waste ranges from about 5 to 100 pounds per square inch.
Claim 4
Dependent Claim
167 words
A primary sewage treatment system for the conveyance and incineration of sewage waste which comprises (1) a supported receiving means with an opening therein situated directly above (2) the inlet chute of a vessel terminating in a conical section, said vessel having a closure valve for closing the top thereof, and an air inlet adjacent to said inlet chute for introducing air under pressure into said vessel, said air inlet being connected to a source of said pressured air through means for controlling the introduction of said air, (3) a discharge pipe connected to the bottom of the conical section of said vessel, said discharge pipe extending horizontally from the vessel bottom, then rising to and connecting with (4) an incinerator, said discharge pipe being connected to said incinerator by means of a flared adapter; the introduction of the pressurized air into said vessel being such that the contents of the vessel are forcibly ejected under pneumatic pressure into the discharge pipe and conveyed to said incinerator.
Claim 5
Dependent Claim
167 words
A primary sewage treatment system for the conveyance and incineration of sewage waste which comprises (1) a supported receiving means with an opening therein situated directly above (2) the inlet chute of a vessel terminating in a conical section, said vessel having a closure valve for closing the top thereof, and an air inlet adjacent to said inlet chute for introducing air under pressure into said vessel, said air inlet being connected to a source of said pressured air through means for controlling the introduction of said air, (3) a discharge pipe connected to the bottom of the conical section of said vessel, said discharge pipe extending horizontally from the vessel bottom, then rising to and connecting with (4) an incinerator, said discharge pipe being connected to said incinerator by means of a flared adapter; the introduction of the pressurized air into said vessel being such that the contents of the vessel are forcibly ejected under pneumatic pressure into the discharge pipe and conveyed to said incinerator.
Claim 6
Dependent Claim
15 words
The apparatus of claim 3, wherein said flared adapted is situated wholly outside the incinerator.
