Abstract: Vacuum carburizing of ferrous workpieces is performed at low pressure in a vacuum furnace using an unsaturated aromatic such as benzene as the carburizing medium. The unsaturated aromatic is gas phase hydrogenated into naphthenes, such as cyclohexane, which is metered into the furnace chamber proper and functions as the carburizing gas. The furnace is constructed to be generally transparent to the naphthenes so that cracking tends to occur at the workpiece which functions as a catalyst to minimize carbon deposits. The unsaturated aromatic is supplied in liquid form to fuel injectors which inject the liquid aromatic as a vapor at duty cycles and firing orders to produce a uniform dispersion of the hydrocarbon gas about the work resulting in uniform carburizing of the workpieces. An in-situ methane infrared sensor controls the process.

Abstract: A system and method of providing privacy through anonymity is described. As one aspect of the invention, a person registers at a privacy server and is given a pseudo identity that can be used to browse, register, purchase, pay for, and take delivery of products and services. Transactions are completed with the privacy server on a need-to-know basis. A seller communicates with the privacy server but only sees a demand, not the identity of the buyer. The financial institution communicates with the privacy server and sees the payment, not the merchandise. The freight company communicates with the privacy server and sees the package, not its contents. The privacy server operates in a manner that assures privacy and anonymity for the buyer and, if necessary, both the seller as well.
