Abstract: A server transmits a message from a sender to a destination address. During transmission, the server and the destination address have a dialog constituting an attachment, via a particular one of SMTP and ESMTP protocols, concerning the message, the server and the destination address. The message passes through servers between the server and the destination address. This passage is included in the attachment. Verifiers are provided for the message and for the attachments. The verifiers may constitute encrypted hashes of the message and of the attachment. The sender receives the message, the attachments and the verifications from the server before authentication and transmits the message, the attachments and the verifiers to the server to obtain authentication by the server. The server operates on the message and the message verifier to authenticate the message and operates on the attachments and the attachments' verifier to verify the attachments.
Abstract: A system and a method are provided for removing greenhouse gases, particulates and pollutants from the atmosphere utilizing a greenhouse gas collection apparatus. An atmospheric mixture is collected and progressively treated in first, second and third tube furnaces and a scrubber to produce an effluent for treatment in a chemical processing plant. The first tube furnace oxidizes hydrocarbons, the second tube furnace oxidizes any remaining nitrous and nitric oxides, and the third tube furnace oxidizes sulfur dioxide. The scrubber precipitates carbon dioxide as calcium carbonate. A vacuum pump draws the atmospheric mixture through tube furnaces and the scrubber.
Abstract: A system and method are disclosed for automatically limiting the drainage of a bodily fluid such as cerebrospinal fluid (CSF) from a patient into a collection chamber. The collection chamber includes a vent having an hydrophobic filter for the passage of air to facilitate the movement of CSF yet to maintain a closed system. The system includes a buoyant float hingedly connected with the top of the collection chamber in one embodiment. When fluid rises in the collection chamber to a predetermined volume, buoyant force raises the float and causes a seal plug mounted on top of the float to seal one of an inflow port or a vent port. The float is limited to pivoting movement in one plane and to a certain angle within that plane. The system and method avoid overdrainage of CSF from the patient and overfilling of the collection chamber.

Abstract: A system prevents oxidation of a laser cut workpiece by utilizing a laser source that utilizes laser source with an inert gas, such as argon or helium, rather than air or oxygen, to create the slots or kerfs which form the pattern cut into the workpiece. The system introduces oxygen gas through the workpiece as it is being laser cut to oxidize any slag or dross created during the laser cutting process. Oxygen or a mixture of oxygen with other gases cools the slag and the workpiece while at the same time oxidizing the slag to either completely burn or partial burn the slag before it strikes an exposed surface of the tubular member.

Abstract: In order to provide third party verification of the content and delivery of an electronic message such as an e-snail, a server receives the e-mail intended to be sent or forwarded to a specified addressee, and “tags” the message to indicate that it is “registered” with the provider of the service. The server then establishes a direct telnet connection with the addressee's Mail User Agent (MUA), and transmits the tagged email to the addressee's MUA, as well as to the MUA's of any other addressees. After receiving responses from the receiving MUA's that the message was successfully received, the server then creates and forwards to the message originator an electronic receipt.
