Patent CA-2403884-A1 (CA)
Inventor: REANEY MARTIN J T
IPC: C11B13/02
Filed: 2001-03-21
Abstract: Methods for acidification of soapstock and recovery of acidulated fatty acids, conversion of the acidulated fatty acids to esters, and crystallizing the acidulated fatty acids from the extraction solvent using urea are disclosed. The novel method of adding both a monohydric alcohol to the soapstock to lower viscosity and a strong acid to hydrolyse the soaps prevents the formation of emulsions of soaps and oils, see figure 1. This allows the quantitative recovery of fatty acids and glyceride from the soapstock by removal of the alcohol by evaporation. Alternately, the fatty acids and glyceride may be converted to esters of monohydric alcohols. Heating the fatty acid, glyceride and monohydric alcohol solution produces fatty esters of the extractive alcohol. Chilling the fatty acid, glyceride, and monohydrici alcohol solution allows the selective crystallization of fatty acids. Treating the fatty acid, glyceride and monohydric alcohol solution with urea allows the specific crystallization of fatty acids. The acid water released from this novel process is heavily laden with both organic and inorganic solutes. Processes for recovery of valuable inorganic and organic constituents from the acid water are also described.

Filed: 2001-06-29
Abstract: A reservoir-electrode for an iontophoretic delivery device of the present invention includes an electrode; and a hydrophilic reservoir situated in electrically conductive relation to the electrode. The reservoir is formed from a bibulous hydrophilic cross-linked polymeric material having a substantially uniform concentration of an alkali metal chloride salt therein thereby substantially eliminating concentration gradients of the salt with respect to the electrode. The polymeric material has a first surface and a second surface that is adhesively adherent to the electrode. The first surface of the polymeric material is releasably adhesive to an applied area of a patient's skin. The polymeric material has a cohesive strength, wherein a bond strength of an adhesive bond between the second surface of the polymeric material to the electrode is greater than the cohesive strength of the polymeric material and an adhesive bond strength of the first surface of the polymeric material to the applied area of the patient is less than the cohesive strength of the polymeric material so that upon removal of the reservoir-electrode from the applied area of the patient, substantially no polymeric material remains on the applied area and the reservoir remains substantially intact and adhesively adherent to the electrode.

Title: Code identification method and system
Inventor: KEECH WINSTON DONALD
IPC: G06Q20/00
Filed: 2001-09-07
Abstract: A method and system for secure identification of a person in an electronic communications environment, wherein a host computer is adapted to be able to communicate with a specific electronic communications device operated by the person. The person is issued with a mask code, known only to the person and stored in the host computer, but never transmitted electronically therebetween. When th person is required to identify him- or herself to the host computer, the host computer transmits a pseudo-random string to the specific electronic communications device, whereupon the mask code must be applied to the pseudo-random string according to predetermined rules so as to generate a volatile identification code which is then transmitted back to the host computer. Positive identification is achieved when the volatile identification code matches a volatile identification code generated within the host computer by applying the mask code stored therein to the pseudo-random string. In this way, a person's mask code is never transmitted electronically and is therefore relatively safe from interception, and the volatile identification code will be different for each different pseudo-random string, thus making a fraudulently intercepted communication meaningless.

Patent CA-2427498-A1 (CA)
Title: System and method for using location identity to control access to digital information
Inventor: SEILER MARK
IPC: G06F21/00
Filed: 2001-10-30
Abstract: A method and apparatus for controlling access to digital information utilizes a location identity attribute that defines a specific geographic location. The location identity attribute is associated with the digital information such that the digital information can be accessed only at the specific geographic location. The location identity attribute further includes a location value and a proximity value. The location value corresponds to a location of an intended recipient appliance of the digital information, and may be further defined in terms of latitude, longitude and altitude dimensions. The location identity attribute is enforced by allowing access to the digital information only at the specific geographic location. As a first part of this enforcement process, the location of an appliance through which access to the digital information is sought is identified. The appliance location is then compared to the specific geographic location defined by the location identity attribute, and access to the digital information is allowed only if the appliance location falls within the specific geographic location. There are many ways to identity the location of the appliance, including: (1) resolving the appliance location from a street address for the appliance; (2) retrieving the appliance location from a file stored within the appliance; (3) recovering the appliance location from a GPS receiver embedded in the appliance; and (4) recovering the appliance location by triangulating RF signals received by the appliance.

Title: Process for selective hydrogenation of alkynes and catalyst therefor
Inventor: RYU J YONG
IPC: B01J23/72
Filed: 2002-03-13
Abstract: Acetylenic compounds in olefin streams such as mixed 1,3-butadiene were selectively hydrogenated over the supported copper catalysts on highly porou s supports such as alumina, silica, etc. The preferred supports have the avera ge pore diameter larger than about 200.ANG., no micro pores, total pore volume larger than about 0.65 cc/g, and preferably less than about 230 m2/g BET surface area. The copper catalysts were preferably promoted with the group VIII metal such as palladium to improve low activity of copper catalyst. The product stream typically contains less than 20 ppm total alkynes. Also the copper catalysts and the palladium promoted copper catalysts may be modified with zinc oxide to improve the performance of the catalysts. The reactor was loaded with two or more copper catalysts promoted with different levels of palladium. Preferably the copper catalysts were also modified with silver, gold or both silver and gold to reduce polymer formation by the copper component of the catalyst, improve the yield of olefins such as 1,3-butadien e, and prevent the loss of copper and/or palladium due to leaching out into the liquid phase of hydrocarbon.
