Patent CA-2175945-A1 (CA)
Inventor: EBNER ROBERT E
IPC: G01C21/20
Filed: 1996-05-07
Abstract: The integrated GPS/inertial navigation apparatus utilizes satellite signals received with two spatially-separated antennas to achieve improved heading estimates for a mobile platform. Each satellite signal comprises one or more component signals with each component signal having a different carrier frequency. The integrated GPS/inertial navigation apparatus consists of a receiver and an inertial navigation system. The receiver measures the carrier phase of each of one or more component signals of one or more satellite signals received by each of the two antennas during successive time periods of duration Tp. Phase measured during a Tp time period is called Tp-phase. Only one component signal of one satellite signal received by one antenna is measured during any Tp time period. The receiver utilizes the Tp-phases of each component signal obtained during a Tk time period to estimate the phase of the component signal at the end of the Tk time period, the estimated phase at the end of the Tk time period being called the Tk-phase. The inertial navigation system, comprising inertial sensors and a digital processor, utilizes the Tk-phases in determining the heading of the vehicle and the displacement of each of the two antennas from the inertial sensors of the inertial navigation system. The measured phase of a component signal is subject to error as a result of the satellite signal traversing the ionosphere. The inertial navigation system achieves more accurate estimates of heading and antenna displacements by utilizing the Tk-phases in determining ionospheric corrections to phase.

Title: Dual Mode Modulated Backscatter System
Inventor: SHOBER R ANTHONY
IPC: H04B7/26
Filed: 1996-05-27
Abstract: A radio communication system includes an Interrogator for generating and transmitting a first modulated signal by modulating a first information signal onto a radio carrier signal, the first information signal indicating in which of multiple response modes a receiving Tag should respond. One or more Tags of the system receive the first modulated signal and decode it to obtain the first information signal. A Backscatter Modulator modulates the reflection of the first modulated signal using a second information signal whose content, data rate, or modulation is determined by said first information signal, thereby forming a second modulated signal. The Interrogator receives and demodulates the second modulated signal to obtain the indicated second information signal.

Title: Method for treating oil production systems
Inventor: KISSEL CHARLES L
IPC: C09K8/524
Filed: 1996-08-28
Abstract: Solutions of dithiocarbamate salts, such as the sodium salts of N-methyl dithiocarbamate and N,N-dimethyl dithiocarbamate, can be utilized as admixtures with acids, to provide admixtures that are non-corrosive to mild steels in the treatment of oil production systems. Some admixtures are even corrosion inhibiting. Both general corrosion and pitting corrosion forms are affected by the dithiocarbamate admixtures.

Patent CA-2186970-A1 (CA)
Inventor: MOCHIDA NORIHIRO
IPC: H01C1/14
Filed: 1996-10-02
Abstract: A positive thermistor device includes a positive thermistor element having a pair of opposed electrodes, each of which receives compressive force elasticallyapplied from a corresponding one of spring contact members to hold the thermistor element at a predefined position in the device.  When the thermistor device is destroyed, the element breaks into fragments, some of which remain in contact with the spring contact members.  The remaining fragments deviate in position to ensure that they do not conduct electricity, resulting in an open state, wherein any current flow is inhibited through such fragments.  More specifically, a positive thermistor disk is held within the device so that it is interposed between conductive spring contact pieces and insulative position-alignment projections, which are cross-diagonally situated with respect to each other.  The spring contact pieces are located further toward the periphery of the disk than the position-alignment projections, causing a spring force to extend in a direction generally outward relative to a direction perpendicular to the planes of the electrodes.  In one embodiment, theposition-alignment projections have cut-away portions at outer tip ends thereof respectively to further promote the formation of an open circuit state upon the occurrence of malfunction.

Patent CA-2192719-A1 (CA)
Inventor: LOEPFE MARKUS
IPC: G01N33/00
Filed: 1996-12-12
Abstract: In a process for the detection of organic vapours and aerosols by surface ionisation, more particularly amines, hydrazines and nitrogen-containing compounds that are produced from fires, the molecules concerned condense on a conductive device (4).  Said device is heated by current pulses through a resistance heating (5) as a result of which the condensed molecules are thermally ionised.  The ions produced are collected by a collector electrode (9) and the resulting ion current pulse is amplified by a transimpedance circuit (15).  The current pulse for heating the conductive device (4) lasts until the ion current pulse has subsided and the conductive device (4) is freed from residual substances.  As a result, the conductive device remains free from fouling and has a longer service life.  The time-averaged power consumption of the process is less than 2 mW.          The conductive device (4) has a resistance, zigzag-shaped heating (5) which is arranged as a thin layer on an Si3N4 membrane (3) which lies over an opening (2) of an undercut silicon chip (1). In another embodiment of the conductive device (4), a conductive layer (8) separated by an insulating layer (7) is arranged on the resistance heating (5).

Title: Well completion lubricator valve
Inventor: EDWARDS JEFFREY CHARLES
IPC: E21B47/10
Filed: 1995-05-22
Abstract: Apparatus and a method of isolating a well to allow intervention equipment to be installed in the upper section of tubing and surface equipment to be tested prior to running in the well is described which enables a surface test tree to be leak-off tested on a regular basis and enables the SSTT valves to be pressure tested before opening and after relatch. This is achieved by providing a completion lubricator valve comprising a fail open valve (18) located above a conventional downhole safety valve (20), the fail open valve (18) being closable by the application of hydraulic closure pressure (42) to allow a pressure differential to be supported from above. The valves (18, 20) are flapper valves and are spring-biased to open or closed positions as necessary. This allows the intervention equipment to be installed in the upper section of the tubing and the surface equipment to be tested prior to running in the well and enables the injection head to be installed immediately upon the production tree.

Title: Apparatus for the resharpening of two-dimensionally acting knife sets for flaking machines, especially for wood flaking machines
Inventor: PALLMANN WILHELM
IPC: B27L11/00
Filed: 1997-02-06
Abstract: The  invention  relates  to  the  resharpening  of two-dimensionally acting knife sets in knife rims as they are used for the industrial production of wood flakes  from long logs and wood cut to length. Each knife set consists of a knife plate provided with a cutting edge and of several scoring organs whose scoring blades are tightly linked to the knife plate  according to the  invention.          After having advanced all knife sets their resharpening is done in a first phase by means of a grinding drum provided with ring grooves while the knife rim is rotating slowly.          In a second grinding phase the cutting edges are touched by  the  grinding  drum  which  moves  slightly  in  axial direction and for that purpose the knife rim is arrested intermittently. During this phase the residues remaining on the cutting edges and at the scoring organs in the area of the ring grooves are ground off.          Due to the present invention it is possible to resharpen the knife rims  inside of  the flaker via an automatic programmed control without loss of production and without the  assistance  of  maintenance  personnel  so  that  the flaking operation is not interrupted and the knife sets are always perfectly sharp.
