Abstract: In a sewage treatment plant, dissolved ammonium is extracted from the waste- water stream, and is transferred to a body of secondary water. The secondary water is pass ed through an electrolysis station, where the ammonium is transformed to nitrogen gas. The capture and transfer can be done by ion-exchange, the electrolysis then being done an th e regenerant water. Or the capture and transfer can be done by first transforming the dissolved ammonium to ammonia gas by raising the pH of the waste-water, then passing the ammonia g as through acidic secondary-water, in which the ammonia dissolves, the electrolysis the n being done on the acid-water. The electrolysed, ammonium-diminished, secondary-water can be re - used in further capture/transfer episodes. The secondary-water does not mix with the waste- water stream.

Abstract: The invention relates to means for protecting information systems against a nonauthorised intrusion. Said invention makes it possible to form a pass- through circuit for protecting a data distributed processing. The access to a computer system being obtained on a user device and on a server for the data distributed processing, a system of internal and external keys based on secr et keys received from a centre for certifying, forming and distributing keys is formed. Secret internal single-use keys for a symmetrical encryption mode us ed for data transmission, storage and processing are generated, and a connectio n request to a pre-selected server is sent from the user device to the certification centre. Open keys on which the external single-use keys for symmetrical encryption mode are generated are received. For transmission to the server, sent information is encrypted by using a stochastic coding involving the use of the external single-use keys. Said information is also encrypted using secret internal single-use symmetrical keys, processed, stochastically coded and sent to the user device.

Title: Retractable truck tarpaulin system
Inventor: POYNTZ PHILIP
IPC: B60J7/08
Filed: 2004-03-10
Abstract: A retractable trailer enclosure system for use in covering at least part of the bed of a truck trailer having removable U-shaped bows vertically mounted thereon. The trailer enclosure system includes a flexible cover which may be retracted to permit access to the trailer bed surface, or extended to cover the trailer bed and any goods positioned thereon. An elongated spindle is provided which is mounted to the trailer by means of a spindle mount assembly. The spindle is used to wind the cover, coiling or uncoiling it thereabout in its retraction or extension. The spindle is movably supported in an orientation with its spindle axis generally parallel to the upper surface of the trailer bed by a spindle mount, with the spindle mount used to secure the spindle so that it may be moved along a generally arcuate extending path or corridor. The spindle mount consists of a pair of spaced pivot rods elongated so as to extend from a first end portion to a second distalmost end portion. The first end portion of each of the pivot rods is secured to an associated pivot aligned with a pivot axis oriented parallel to the spindle axis. The pivot rods are mounted such that the second end of each rod may be movable from a generally lateral orientation along the arcuate path or corridor about the pivot axis. Each pivot rod is provided as a telescoping rod with the distalmost end being movable radially outwardly from the pivot axis. A tensioner is provided to resiliently bias the distalmost end to the retracted position. A manual electric or other power drive is used to selectively rotate the spindle to thereby extend or retract the tarp over the bows. When the tarp is in an initial extended position covering the trailer bed and bows, the initial rotation of the spindle about its spindle axis results in the winding of the cover about the spindle. As the cover is coiled about the spindle, the spindle is drawn by advancing along the tarp in movement over the arcuate path. In a similar manner by reversing the direction of rotation of the spindle, the tarp is unwound to recover the trailer bed and bows.

Title: Method for making silica supported, crush-resistant catalysts
Inventor: HU YATAO
IPC: B01J37/06
Filed: 2002-09-25
Abstract: A method for making a silica supported catalyst involves impregnating a silica component with a catalytic metal using an aqueous, alkaline bath before drying. More specifically, the method involves forming and washing a silica component, such as a silica gel or a co-gel, for example a silica-zirconia co-gel. Then, the washed silica component is contacted with the alkaline bath to effect the impregnation with the catalytic metal, such as cesium, to form an activated silica component. Subsequently, the activated silica component is dried to form the catalyst. The resulting catalysts demonstrate good mechanical strength.

Title: Improved dept collection practices
Inventor: FOURER ROBERT
IPC: G06Q30/00
Filed: 2002-11-05
Abstract: A method of optimizing debt collection attitudinally classifies debtors into one of several attitudinal segments. The approach uses an assement of current attitudes rather than past behaviors as to predict future behavior. Each segment can be addressed with an offer, which is a combination of attributes which together, have an expected, measurable, and predictable response from the debtor. Debt collection requires the expenditure of resources, at least one of which the availability of a relatively small number of debt collectors.  The offers that can be extended to debtors are identified on a debtor-by-debtor, offer-by-offer basis to identify the best offer to propose to each debtor by the limited number of debt collectors in order to maximize the economic return from all debtors. Figure 6 (600) depicts the steps (608, 610, 612) of a method of assigning a debt collection task to a particular debt collection resource or group resources.
