Title: Method for the recover of elemental sulfur from a gas mixture containing h2s
Inventor: HEISEL MICHAEL
IPC: C01B17/04
Filed: 1995-03-17
Abstract: This invention is a method for the recovery of elemental sulfur from a gas mixture containing H2S.  The gas mixture is first subjected to desulfurization in a Claus installation which has a thermal part and a catalytic part resulting in the recovery of elemental sulfur.  Sulfur compounds still contained in the Claus tail gas are then transformed into H2S by means of hydrogenation and,  if necessary,  by means of hydrolysis and the hydrogenated Claus tail gas is subjected to catalytic direct oxidation of the H2S to elemental sulfur.   The Claus installation comprises exactly one catalytic stage and the catalytic direct oxidation also takes place in exactly one reactor.    Sulfur recovery rates of 99.3% to 99.6% are achieved by the method of the invention.

Title: Separation process
Inventor: PARKER DAVID
IPC: B01D9/00
Filed: 1994-02-09
Abstract: A slurry containing crystals in an impurity-containing mother liquor under elevated pressure and temperature conditions is processed to separate the crystals from the mother liquor. The processing comprises highly efficient separation and washing of the crystals under the elevated temperature and pressure conditions in a unit (32) to produce a mass of crystals having a low level of contamination. The washed crystals are reslurried in aqueous medium (vessel 40) and transferred to a secondary separation unit (34) operating under lower pressure and temperature conditions, the transfer being effected by flashing down (in vessel 44) to the lower pressure. The filtrate (41) from unit (34), and optionally wash liquor used in unit (34), is used to establish a recirculating flow whereby the aqueous medium used for reslurrying the crystals prior to pressure let-down is repeatedly re-used.

Title: A process and apparatus for treating waste water
Inventor: DESJARDINS GAETAN
IPC: C02F3/28
Filed: 1995-09-15
Abstract: The process for treating waste water uses the combination of a septic tank operating in series with a biological reactor such as a sequencing batch reactor. In this process, waste water is supplied and accumulated in a septic tank. In the septic tank, the waste water and the settling sludge are biologically treated under anaerobic conditions. A given amount of treated waste water is then transferred from the septic tank into a biological reactor such as a sequencing batch reactor, where it is mixed and aerated. Such a mixing and aerating causes activation of the sludge and clarification of the waste water. The activated sludge in suspension in the liquor is then allowed to settle and an upper layer of clarified water formed above the mixed liquor after the settling period is decanted. The excess activated sludge in the biological reactor may then be removed therefrom and supplied into the septic tank so that the excess sludge be treated by digestion therein. The apparatus used to carry out the above-mentioned process comprises a septic tank provided with a baffle wall defining a first chamber where the sludge may settle and accumulate and where anaerobic fermentation is occurring, and a second treatment chamber where the solids are anaerobically digested. In operation, the waste water may flow from the first chamber to the second chamber by passing through the baffle wall. The apparatus also comprises a biological reactor for further treating the waste water under aerobic condition. A pump is provided for transferring the treated waste water in the septic tank to the biological reactor. This process allows a total treatment of waste water and all sludge for an extended period of time, from 5 to 15 years, without having to remove any byproducts for immediate treatment.

Title: Method of recalibrating electronic scales
Inventor: BASS EDWARD R
IPC: G01G23/01
Filed: 1996-03-01
Abstract: A method of recalibrating an electronic scale is disclosed which causes the scale to indicate accurate weight measurements regardless of variations in the relative magnitude of the force of gravity under which the scale is operating between a site of origin where it is calibrated, and a site of installation which tend to adversely effect accurate weight. The method utilizes the known principles of gravity that it varies from place to place as afunction of elevation above sea level and proximity to the equator. Certain data relating to the effect on the accuracy of the scale due to variations in the gravitational force between a site of origin and a site of installation is placed in memory in the scale at a site of origin, where the scale is initially calibrated. When corresponding data indicative of the variation in the magnitude of gravitational force at the site of installation is then entered into the scale, the microprocessor of the scale adjusts the factory calibration to compensate for the difference in the magnitude of the force of gravity so that the digital readout of the scale indicates accurate weight for mail pieces placed thereon at the site of installation.
