Patent CA-2321316-A1 (CA)
Inventor: MOHAUPT HENRY H
IPC: E21B43/11
Filed: 2000-09-27
Abstract: A hydrocarbon producing well is treated by first igniting a gas generating charge in the well to clean out perforations communicating between the casing and the formation without creating high permeability channels adjacent the perforations or fracturing the formation in a macroscopic sense. Then, a treatment liquid is injected into the wells by a gas generating propellant charge placed in the production string and then ignited. The propellant charge is designed to produce a minimum horsepower sufficient to push the liquid more-or-less equally through all of the open perforations. The propellant charge is designed to produce a maximum horsepower which is less than what is necessary to fracture the formation. Basically, the combustion rate of the propellant charge is reduced by one of a multiplicity of techniques to produce a long, relatively slow combustion rate.

Patent CA-2330731-A1 (CA)
Inventor: LEARY JEFFREY J
IPC: C12Q1/6874
Filed: 1999-06-18
Abstract: A genetic analysis method termed "fine array transcript mapping" or "FAT Mapping" is disclosed, which method is useful for detecting and measuring RNA molecules which have been transcribed from a genome. The method can be applied to explore differential expression of a template genome, and for accurately mapping the 5' ends of transcripts which have been expressed. Further, the presence or absence in any particular biological circumstances of a given transcript and its relative concentration can define gene functions or coding capacities. Thus the method relates to mapping and identifying novel and known gene products and investigating gene functions and regulation.

Title: Intelligent electrical devices
Inventor: BRUWER FREDERICK JOHANNES
IPC: H05B37/02
Filed: 1999-10-08
Abstract: The present invention provides for a unique microchip or circuit which can, inter alia, handle both current conducting functions and man-machine-interface functions in an electrical device, for example, such as a flashlight. The man-machine-interface functions, according to the present invention, may be controlled by very low current signals, touch pads, carbon coated membrane type switches, or other low current type switches. These low current switches are smaller, more reliable, less costly, easier to seal, and less vulnerable to corrosion and oxidation than prior art switches. Moreover, since according to the present invention, the current conducting switch is controlled in an intelligent manner by the same microchip which provides the man-machine-interface functioning, significant costs savings and reliability are achieved by the invention. The present invention, according to one embodiment, also provides a microchip or circuit which may be embedded into a power source, for example, a battery, that supplies intelligence to the same. As a result, and according to the invention, functions such as delayed switching, dimming, delayed automatic shut off and an intermittent activation may be realized in less intellligent prior art electrical devices. According to certain embodiments of the present invention, the inventive microchips or circuits of the present invention can, inter alia, adjust the average electrical current through a current switch , provide an "on" and "off" sequence which, in the case of a flashlight, can be determined by an operator and may represent either a flash code sequence or a simple on-off oscillation, delayed shut off function, dimming function, provide indication of power strength, and provide gradual oscillating current flow to lengthen the life of the operating switch and the battery, etc. The function can be selected by varying the time period which elapses between successive activations of a controlling switch.

Patent CA-2358018-A1 (CA)
Inventor: KERNER THOMAS M
IPC: H03L7/113
Filed: 2001-10-02
Abstract: The present invention provides a wide tracking range phase locked loop (PLL) circuit that achieves minimal fitter in a recovered clock signal, regardless of the source of the fitter (i.e. whether it is in the source or the transmission media). The present invention PLL has automatic harmonic lockout detection circuitry via a novel lock and seek control logic in electrical communication with a programmable frequency discriminator and a code balance detector. (The frequency discriminator enables preset of a frequency window of upper and lower frequency limits to derive a programmable range within which signal acquisition is effected. The discriminator works in combination with the code balance detector circuit to minimize the sensitivity of the PLL  circuit to random data in the data stream). In addition, the combination of a differential loop integrator with the lock and seek control logic obviates a code preamble and guarantees signal acquisition without harmonic lockup. An adaptive cable equalizer is desirably used in combination with the present invention PLL to recover encoded transmissions containing a clock and/or data. The equalizer automatically adapts to equalize short haul cable lengths of coaxial and twisted pair cables or wires and provides superior fitter performance itself. The combination of the equalizer with the present invention PLL is desirable in that such combination permits the use of short haul wires without significant jitter.
