Patent CA-2124961-A1 (CA)
Title: Fishing lure
Inventor: HIRVONEN HEIKKI S
IPC: A01K85/16
Filed: 1992-12-03
Abstract: A lure comprising a body element (1), a moving element (2; 15) and a fly (5) or hook. The moving element, e.g. a paddle wheel (2), is arranged to the body element (1) so that it is rotating when the lure is drawn through water. The fly is attached to a moving element at a distance from the lure body, said element being more suitably guided and supported by the line (6) of the lure. The moving element (2) of the lure makes, via the wire (3), the fly (5) move back and forth, thus creating an additional luring effect for the fish. The guiding effect in the line (6) is created, e.g., so that a loop (4) through which the line (6) is running is formed in the wire (3) near the fly (5).

Patent CA-2145015-A1 (CA)
Title: Hybrid condensation-absorption olefin recovery
Inventor: PHILLIPS CHRISTOPHER L
IPC: C10G70/06
Filed: 1995-03-20
Abstract: A hybrid condensation-absorption process and unit is disclosed for the recovery of olefins. A mixed-component stream containing hydrogen, methane and olefins is compressed and refrigerated against propylene refrigerant to partially condense the stream. The condensate is stripped of volatile components and fed to a fractionation unit such as a deethanizer. The volatile components stripped from the condensate and the non-condensed vapor from the mixed-component stream are fed to a solvent absorption unit to remove olefins which are absorbed in the solvent. The olefins-rich solvent is regenerated to recover olefins and lean solvent. The lean solvent is recirculated to the absorption unit. The olefins recovered from regeneration of the solvent are fed to the fractionation unit along with the pre-stripped condensate.      Vapor from the absorption unit is cryogenically processed to recover a crude hydrogen product, a fuel gas product and residual olefins which can be recycled to the absorption unit. The hybrid process eliminates the need for low temperature (ethylene) refrigeration equipment, generally required by conventional condensation-based olefins recovery technology, and substantially reduces the solvent recirculation rate to the absorption unit and eliminates hydrogen expansion as compared to conventional absorption-based technology.

Title: System for reading encrypted information and unit for use in such a system
Inventor: JERNBACKER LARS
IPC: G06F21/84
Filed: 1994-11-10
Abstract: A computer system for reading encrypted information is disclosed. A unit (24) for decrypting the information is open only as long as a display tool (A4) occupies a system-modal operative mode (SM). In this system-modal operative mode, the display tool (A4) emits, to the decrypting unit (24), a predetermined enabling signal (BS) without which the decrypting function does not work. When the display tool occupies the system-modal operative mode, the user does not have access to the user functions not defined by the display tool, thereby preventing unauthorised copying, storage and the like of the decrypted information.
Patent CA-2152668-A1 (CA)
Title: Memory management of compressed memory pages
Inventor: SLAYDEN GLENN C
IPC: G06F12/08
Filed: 1994-11-18
Abstract: A method of implementing data compression in a working memory of a computer, the working memory being implemented using random access memory (RAM). The compression method operates by dividing the working memory into a plurality of memory blocks that includes an uncompressed memory block and a compressed memory block. The compression method stores uncompressed data, including instruction code, in the uncompressed memory block during processing of the uncompressed data. Data that is not currently being processed is stored in compressed form in the compressed memory block. When a portion of data, such as a 4 kilobyte data page, is desired for processing, the compression method first determines whether the page is located in the uncompressed or the compressed memory block. If the data page is located in the compressed memory block, then the compression method creates space for the data page in the uncompressed memory block by compressing one of the pages in the uncompressed memory block and storing it in the compressed memory block. The requested compressed page is then transferred to the uncompressed memory block and is decompressed. Processing continues with the decompressed page without the user or application knowing that the page was previously in compressed form.

Inventor: NATANZON ALEX
IPC: A61B6/00
Filed: 1995-07-31
Abstract: A system for recording fewer of the events that are caused by unwanted photons with greater stability.  The system locally determines the energy spectrum and fits for each pixel of the image the determined energy spectrum with a modified trial function composed of: a photopeak component of known energy shape, Compton scatter components having theoretically derived energy shapes and, when applicable, also measured or calculated energy spectra of other unwanted photons. The modified trial function also takes into consideration unknown local deviations in the outputs of electronic components.  The amplitude of the photopeak distribution resulting from the fit is used to obtain the local content of wanted interactions in the image.  This enables removal of Compton contamination and also the contamination caused by interaction of the gamma photons with lead components.

Title: A method of making a tooth mold
Inventor: DEHOFF BARRY D
IPC: A61C13/00
Filed: 1995-08-03
Abstract: A method is described for the making of a high definition tooth mold which includes the steps of scanning the surface of a model of a tooth, processing the data in a CAD/CAM computer, and using the processed data to fabricate a tooth mold. The scanning step involves subjecting a rotating tooth model to radiant energy, receiving and translating reflections of the radiant energy into electronic signals, and digitizing the signals into data of the three-dimensional surface locations of the tooth model.      The processing step involves translating the data, editing the data, creating a three-dimensional surface pattern of the tooth model, evaluating the surface pattern and creating a new three-dimensional surface pattern until an acceptable high definition surface pattern is achieved by adding supplemental data or repeating the scanning step. Finally, creating a tooth path program used in the fabricating step to mill a tooth mold.
