Patent CA-2204588-C (CA)
Inventor: ONDRACEK JIRI
IPC: A62C37/14
Filed: 1997-05-06
Granted: 2003-01-14
Abstract: In the particular embodiments described in the specification, a dry sprinkler has a tube-like section with a sprinkler head at one end and a threaded portion to be received in a water supply line at the opposite end and it includes an internal support structure extending between a sealing plug in the end to be received in the water supply line and a cap in the sprinkler head which is supported by a thermally responsive structure. In one embodiment, the support structure includes a rod on which the sealing plug is mounted at one end and having a cap-engaging tip at the opposite end which is shaped to facilitate the flow of water from the sprinkler head toward a deflector, the rod being spaced from the tube-like section by two guide members, one of which acts as a stop for motion of the structure toward the sprinkler head and the other which engages a spring urging the structure toward the sprinkler head. In other embodiments, a spacer is inserted between the end of the rod and the cap in the sprinkler head and a separate rod tip may be inserted between the rod and the spacer. In a further embodiment, an inner tube extends between the cap and the sealing plug and is shaped with spaced triangular tips to support the sealing plug in the unactuated condition and a water supply line connection which is coupled to the water supply line has a lateral cavity recess to receive the sealing plug out of the path of water flowing through the inner tube when the sprinkler is actuated.
Patent CA-2205678-C (CA)

IPC: C10L3/06

Granted: 1999-10-05
Abstract: For storage of natural gas at pressures over 1,000 psia, it is advantageous to add to natural gas an additive which is a C2 or C3 hydrocarbon compound, or a mixture of such hydrocarbon compounds. Above a lower limit (which varies with the additive being added and the pressure), a decrease in the amount of power needed to compress the mixture. For storage or pipeline transportation of natural gas at pressures over 800 psia, it is advantageous to add ammonia to the natural gas, in an amount such that the ammonia does not create a liquid phase at the temperature and pressure used. The ammonia-natural gas mixture can be compressed or pumped with a lower energy expenditure than would be needed for an equivalent volume of natural gas alone. When more than 4% by volume of ammonia is present, the pumping through pipelines is also aided by the refrigerant effect of the ammonia, which reduces the temperature of the gas being transported.   Instead of ammonia, hydrogen fluoride or carbon monoxide can be added to the natural gas, but these are less preferred than ammonia.

Title: Method and apparatus for adaptive line enhancement in coriolis mass flow meter measurement
Inventor: RAJAN SREERAMAN
IPC: G01F1/84
Filed: 1996-07-03
Granted: 2001-11-06
Abstract: An apparatus and method for determining frequency and phase relationships of vibrating flow tubes in a Coriolis mass flow meter. Adaptive line enhancement (ALE) techniques and apparatus are used in a digital signal processing (DSP) device to accurately determine frequency and phase relationships of the vibrating flow tube and to thereby more accurately determine mass flow rate of a material flowing through the mass flow meter. In a first embodiment, an adaptive notch filter is used to enhance the signal from each corresponding sensor signal on the vibrating flow tubes. In a second embodiment, a plurality of adaptive notch filters are cascaded to enhance the signal from each corresponding sensor signal. In both embodiments, an antialiasing decimation filter associated with each sensor signal reduces the computational complexity by reducing the number of samples from a fixed frequency A/D sampling device associated with each sensor signal. Computational adjustments are performed to compensate for spectral leakage between the fixed sampling frequency and the variable fundamental frequency of the vibrating flow tubes. Despite this added computational complexity, the present invention is simpler than prior designs and provides better noise immunity due to the adaptive notch filtration.  Heuristics are applied to the weight adaptation algorithms of the notch filters to improve convergence of the digital filters and to reduce the possibility of instability of the filters interfering with mass flow measurements.

Inventor: SAZHIN SERGEY N
IPC: H01M10/05
Filed: 1997-12-22
Granted: 2010-11-02
Abstract: A process for purification of lithium battery electrolyte solutions is provided whereby the concentrations of trace amounts of impurities such as water in the electrolyte solutions can be reduced. Such electrolyte solutions generally include at least one lithium salt solute contained in at least one organic solvent. Lithium and a second metal with which lithium is capable of intercalating are first placed in electrical contact with one another and then placed in the electrolyte solution. Preferably, aluminum is used as the second metal and the two metals are provided as separate layers that are pressed together in a rolling mill to form a bimetallic sheet. The solution containing the bimetallic sheet is agitated to encourage the reactions which reduce the levels of impurities such as water in the electrolyte solution. The resulting purified solution is then filtered to remove any remaining metal or reaction products. The resulting purified electrolyte solution can be used to make lithium batteries having improved cycling characteristics over batteries using unpurified electrolyte solution.

Title: Automatic speech recognition
Inventor: HOVELL SIMON ALEXANDER
IPC: G10L15/08
Filed: 1997-04-24
Granted: 2002-10-01
Abstract: Speech recognition is carried out by matching parameterised speech with a dynamically extended network of paths comprising model linguistic elements (12b, 12c). The units are context related, e.g. triphone s. Some elements cannot be converted to models at the time when it is necessary to incorporate the element into the paths because the context is not defined at the relevant time. In order to allow transfer the element is transferred as a place marker (21, 22, 23, 24) which  is converted when a later extension completes the definition of the triphone. The place markers (12a) can be used to identify the locations for subsequent extensions.
