Title: John rod
Inventor: RODRIGUEZ JOHN
IPC: E04G21/00
Filed: 1991-04-08
Abstract: ABSTRACT To increase speed in the installation of drywall board (gypsum board) being fastened to ceilings. THE JOHN ROD must be used to hold the drywall board in position allowing the installers to have their hands free to fasten the drywall board. This tool is able to replace the make-shift 2"x4" "T" holders by being able to be used on ceiling installation irregardless of the ceiling heights. It is also light weight and is easily manoeuvred about a construction site. The tool is comprised of three basic components, the "T" holder, the holding mechanism and the final component to THE JOHN ROD is the mount.  The holding mechanism allows the "T" holder to raise to varying heights as may be required. Once the height is found the brake lever automatically holds the "T" holder from slipping downward. The installer can lower the "T" holder by lifting upward on the brake lever. The mount can be in two forms. The base form allows THE JOHN ROD to stand freely on the floor. The second form, the scaffold mount, allows THE JOHN ROD  to be mounted on a scaffold, for high ceiling installation applications. THE JOHN ROD could also be used on other installation applications such as duct work installations by heating/air conditioning installers. Or by converting the "T" holder the tool could be used as an extention of a stock persons arms for lifting stock to greater heights and by photographers for tri-pods and light stands.

Title: Diagnostic Device for Gas Turbine Ignition System
Inventor: FRUS JOHN R
IPC: H01T13/58
Filed: 1991-07-25
Abstract: A device for diagnosing the state of health of an ignition system is provided, where the system includes at least one spark producing channel comprising an exciter, output circuit and igniter plug.  The device provides a diagnosis of the state of health for both the exciter and igniter plug by monitoring the high energy pulses at the output of the exciter.  By monitoring the ignition system at an intermediate point in the system such as the output of the exciter, the sensor and electronics of the device may be completely contained within the electronic environment of the exciter, thereby avoiding any need for attaching sensors at the output of the system adjacent to the igniter plug in order to diagnose the plug's state of health.  As an alternative to the device being built into the ignition system, it can be incorporated into automatic test equipment that produces high energy pulses for delivery to an igniter plug to be tested.  The device is capable of diagnosing failure of either the exciter or the igniter plug and may also be configured to detect the impending failure of the plug.

Filed: 1992-06-29
Abstract: ABSTRACT            DUAL DATA BUFFERING IN SEPARATELY POWERED MEMORY MODULES            Combination of split memory modules, each module partitioned into a first section and a second section.  Each module has its own power source so that the failure of a single power source will not affect the  other modules.   A particular block of data is not stored in both sections of a single module.  Each block of data is stored in the first section of one module and the second section of a different module. Failure of a power supply will not cause a loss in data since the same data is stored in a section of a module not powered by the same power supply.  The failure of all power supplies will not result in the loss of any data if either the  first  or  second  section  of  the  memory  modules  is nonvolatile, i.e., backed up, usually by battery sources.
Patent CA-2072893-A1 (CA)
Title: Combustion process
Inventor: DYKEMA OWEN W
IPC: F23C99/00
Filed: 1991-01-08
Abstract: A combustion process for nitrogen- or for sulphur- and nitrogen bearing fuels wherein fuel combustion is divided, by staged oxygen (preferably in the form of air) injection, into at least two combustion zones. The first combustion zone involves providing fuel-rich stoichiometric conditions under which nitrogen chemically bound in the fuel (i.e. fuel-bound nitrogen) is substantially converted to molecular nitrogen. The second (final) combustion zone comprises at least two stages. In the first stage of the final combustion zone, combustion products from the first combustion zone are further combusted under a condition of fuel-rich stoichiometry, preferably at an oxygen/fuel stoichiometric ratio of from about 0.80 to about 1.0 and at a temperature of less than about 2200 K  (1927 C, 3500 F). In the second stage of the final combustion zone, combustion products from the first stage are combusted at an oxygen/fuel stoichiometric ratio of greater than about 1.0 and at a temperature of less than about 1500 K (1227 C, 2240 F). In this final zone, fuel combustion is completed while formation of new thermal NOx is substantially prevented. Thus, the process may be used to reduce emissions of undesirable nitrogenous compounds (e.g. NOx) which would ordinarily be formed during completion of fuel combustion. The process is particularly appropriate for use with the fuel-rich gases from a burner designed to control air pollutants arising from sulphur and nitrogen in the fuel.

Title: Method of and apparatus for detecting internal faults in information processing systems by pipeline processing
Inventor: OHNO TOSHIAKI
IPC: G06F9/38
Filed: 1992-07-03
Abstract: ABSTRACT OF THE DISCLOSURE        An internal fault of an information processing system, particularly a primary processor for effecting information processing, is detected by pipeline process-ing using a redundant processor which is functionally identical to and effects the same information processing as the primary processor with a one-cycle delay with respect thereto.  The information processing system includes a comparator having three pipeline stages. In the first pipeline stage, an input signal supplied to the primary processor and an output signal produced by the primary processor are introduced.  In the second pipeline stage, the input signal is supplied to the redundant processor, which processes the supplied input signal.          The second stage simultaneously introduces the processed signal from the redundant processor as an output signal thereof and the output signal from the primary processor.          Finally, an output signal comparator in the third pipe-line stage compares the output signal from the primary processor and the output signal from the redundant proc-essor, and indicates an internal fault of the primary processor if the compared output signals disagree.  The primary and redundant processors may comprise general-purpose processors.  Internal faults of the information processing system can be detected without impairing the processing capability of the processors.
