Abstract: A process is disclosed for the synthesis of formaldehyde from methane starting with the oxychlorination of methane to produce methylene chloride. Hydrolysis of methylene chloride yields the product formaldehyde. Byproduct chloroform and carbon tetrachloride are recovered and hydrogenated to provide additional methylene chloride.

Abstract: Carbon disulfide is used as a solvent to extract bitumen from oil sands in an anhydrous countercurrent flow process that is compatible with existing procedures for upgrading bitumen. The solution is then fractionated to separate the carbon disulfide from the bitumen product. The bitumen is then treated with hydrogen to decompose the remaining carbon disulfide. The process should provide high yields and meet environmental concerns.

Abstract: A process is disclosed for the synthesis of methanol from methane comprising three reaction steps operated in tandem. In the first step methylene chloride is produced by the reaction of methane with oxygen and hydrogen chloride. In the second step, methylene chloride is hydrolyzed to formaldehyde, which is hydrogenated in the third step to provide the product methanol.

Abstract: A reactor with swing feeds is provided for oxychlorination. This reactor comprises multiple inlets with controls capable of introducing feed streams sequentially to the reactor.

Abstract: A storage battery is provided comprising appositive electrode of lead, a negative electrode of mercury, and an electrolyte consisting of an aqueous solution of a salt of an alkali metal. Upon charging the battery, lead is converted to lead dioxide and the alkali metal forms the amalgam with the mercury. During discharge, the lead dioxide is reduced to the plumbous state and the alkali metal is oxidized to the positive ion and goes into solution. The mercury is immobilized in one of several alternative ways.

Abstract: The present system and method for prioritizing email and controlling spam provides capability to determine the priority of emails received by an addressee. Such emails are designed to alert an addressee of its priority by the number of times the characters of the email address of the addressee are repeated. The present system and method include a coder/decoder that repeats the characters of an addressee's email address to reflect the priority of the email address assigned by the sender prior to sending the email over a network. The coder/decoder is embodied in software or instructions that are run on an email client or email server that count the number of times these characters are repeated. The greater number of repetitions, the greater the priority of the email.

Abstract: A rechargeable battery is provided such that the positive electrode comprises lead dioxide, the negative electrode comprises at least one alloy, and the electrolyte is alkaline. Upon discharge, the lead dioxide is reduced to lead oxide, and the electrolyte remains unchanged. The alloy of the negative electrode can be a metal hydride. The reactions are reversed when the battery is charged.
