Patent CA-2106672-A1 (CA)
Title: Battery charge monitor and fuel gauge
Inventor: HESS RANDALL L
IPC: G01R31/382
Filed: 1993-01-20
Abstract: ABSTRACT                 BATTERY CHARGE MONITOR AND FUEL GAUGE      A  battery  charge  controller  and  fuel  gauge  which accurately monitors the voltage, temperature, and charge and discharge current of a rechargeable battery, and calculates the battery's charge capacity and charge level.   Each time the battery  is  fully discharged,  any calculated  charge  level remaining is divided by two and subtracted from the previously calculated charge capacity. When the battery is fully charged, the charge level is set equal to the charge capacity.  During subsequent charge and discharge, the current is converted to a coulomb count and added or subtracted from the charge level to maintain an accurate charge level.  Fast charge inefficiency due to temperature is considered by subtracting a temperature proportional factor before the charge level of the battery is updated.  The charge level, voltage and temperature are used to determine the optimal fast charge termination point to achieve full charge and prevent temperature abuse and overcharge.  A fast charge is applied only if the battery is within proper voltage and temperature ranges.  The charge controller includes a microcontroller circuit within the same battery pack as the battery, which is powered by the battery when AC power is unavailable.  The microcontroller circuit consumes very little power, measures circuit errors to assure data accuracy, times periods  of  self-discharge  and  updates  the  charge  level accordingly.  The microcontroller circuit also includes memory to store the battery charge information and a communication port to provide the charge information to a computer system connected to the battery pack.

Title: Closure lid and container
Inventor: GOULETTE STEPHEN L
IPC: B65D17/34
Filed: 1994-02-24
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention relates to a combination closure lid and container which includes a container having a bottom, at least one side wall and a mouth around the top of the wall. Extending outwardly about the mouth is a flat flange.  Extending just beyond the outer edge of the flange and about the container is a trough.  The top outer wall of the trough joins with an outwardly protruding lip so as to produce a peripheral undercut region at the point of joinder.   The innermost reach of the undercut is located at least approximately in the plane of said flat flange.   A lid forms the closure for the mouth of the container and it conforms to (1) the undercut region, (2) the trough and (3) the flat flange.  The lid has a circumferential pre-weakened line located in the region of the lid just above the flat flange when the lid is in place on the container.  The lid also has an integral lift flap located above the flat flange in communication with the pre-weakened line.  The container and lid is dimensioned so that the lid will close the container by conformingly engaging the undercut region and the container can be uncovered by accessing the lift flap, pulling it up to at least partially sever the lid at said pre-weakened line.

Patent CA-2129306-A1 (CA)
Inventor: HAUKENESS MILES E
IPC: F17D1/00
Filed: 1994-07-29
Abstract: Know drips for gas transmission pipelines do not work effectively for two phase liquid-gas flows.  Disclosed is a drip having two parts;a flow separator and a receptacle.  The flow separator comprises a pipe having circumferential apertures in the wall.  Surrounding the pipe and the apertures is a shell that defines an annular passage between the pipe wall and the shell.  Annular gas liquid flow  entering the separator will be divided.  Most of the gas will pass the apertures and continue through the pipe.  Most if not all of the liquid and some gas will pass through the aperture.  It is then passed to a receptacle where the fluid is removed.  The secondary gas flow is then either recombined with the main flow or can be diverted to a secondary system. Periodically the liquid collected in the receptacle can be emptied.

Title: Low nox burner
Inventor: LANG JERRY M
IPC: F23C99/00
Filed: 1994-03-22
Abstract: A low NOx burner combustion system (10) which may be adjusted for optimum burn rates, temperature and oxygen levels. The burner incorporates a plurality of gas nozzles (34, 36, 38) which individually inspirate a portion of the combustion air and a spin vane diffuser (20) to rotate and mix the gases within the primary combustion zone. The diffuser (20) is axially adjustable in order to vary the distance between the vane (20) and the first combustion zone while the blades of the diffuser (20) can be angularly adjusted to optimize the rotation and mixing of the gases. Air for combustion is supplied through a passage (16) to create distinct combustion zones for complete combustion. The flow rate of the combustion air is controlled through a damper (14) in accordance with the burn characterisitics. Further reductions in noxious emissions are accomplished by recirculating flue gases and mixing such gases directly with combustion fuel prior to introduction into the combustion chamber through eductor nozzles (34, 36, 38). Still further reductions are attained by mixing a secondary compound such as water or a chemical into the recirculated flue gases to optimize burn levels thereby reducing emissions.

Title: Wool dyeing utilizing controlled dye addition
Inventor: HOLFELD WINFRIED T
IPC: D06P3/14
Filed: 1993-05-13
Abstract: A process for the dyeing of a fibrous article containing wool with an anionic dye and products produced thereby. The pro-cess includes immersing the article in a dyeing bath of a liquid solvent for the anionic dye. The liquid solvent and the article are heated to a temperature at least equal to the dyeing transition temperature.  At least a portion of the dye is added as a miscible liquid concentrate while the solvent and the article are up to temperature.  Stirring of the bath during the dye addition period and while the solvent and article are up to temperature is done to mix the dye concentrate with the solvent to form a dilute dye solu-tion and to provide a flow of the dilute dye solution relative to the article to cause, on the average, essentially uniform dye trans-port of the anionic dye to the article. The dye addition rate is adjusted so that the dye addition rate is the primary control over the rate of dye uptake by the article.

Title: Heat recovery ventilator
Inventor: GRINBERGS PETER K
IPC: F24F12/00
Filed: 1995-01-13
Abstract: A heat recovery ventilator for use in ventilating a building, the ventilator having a single two-position damper operable such that in one damper position, heat is exchanged between a first flow of fresh air passing through the first path and a second flow of exhaust air passing through the second air path. When placed in the second damper position, fresh air is blocked from entering the ventilator and exhaust air is recirculated, passing through both air paths, and exiting through the fresh air outlet. In this mode of operation, exhaust air is inhibited from exiting through the exhaust outlet due to the relative pressures within the ventilator, thereby inhibiting the formation of a negative pressure within the building.
