Title: Variable word length code decoding method, and a decoder for performing the same
Inventor: WATANABE MITSUHIRO
IPC: H04N1/419
Filed: 1994-09-29
Abstract: ABSTRACT OF THE DISCLOSURE          At least two code tables are used to decode a variable word length code sequence. A first code table stores code information of variable word length codes having code lengths shorter than or equal to 8 bits. In addresses of the first code table corresponding to longer variable word length code than 8 bits, data is stored indicative of longer codes than 8 bits. At first, the first code table is accessed. If the data being read from the first code table indicates a code length not more than 8 bits, an input variable word length code is identified and decoded. If the data being read from the first code table indicates a code length longer than 8 bits, the second code table is accessed and the input variable word length code is identified and decoded.
Patent CA-2134070-A1 (CA)
Inventor: BECKET GILES J P
IPC: G01N31/16
Filed: 1993-06-01
Abstract: The total alkalinity of an aqueous metalworking fluid is monitored and controlled by a continuous titration method that continuously supplies a stream of the metalworking fluid, at a known, controllable flow rate, to a flow through chamber having therein a static mixing element.  Simultaneously and separately a stream of acid titrant, of known acid concentration is injected into the flow through chamber at a known controllable flow rate.  The acid titrant and metalworking fluid mix and react in the chamber and the reacted metalworking fluid exiting the chamber passed  over the tip of a pH electrode.  The pH of the reacted metalworking fluid is continuously monitored and the output of the pH electrode used to adjust the flow of acid titrant to the chamber until an endpoint pH value (typically a pH of 4) is reached.  The total alkalinity is then determined from a) the known flow rates of the aqueous metalworking fluid and acid titrant and the known acid concentration of the titrant or may be determined from calibration curves for XY coordinate plots of volume of titrant vs known metalworking fluid concentration.

Patent CA-2146870-A1 (CA)
Title: Ultrasonic nebulising device
Inventor: CHEIMAN VLADIMIR
IPC: B05B17/06
Filed: 1993-10-15
Abstract: The device is designed for nebulizing liquids and for transporting the formed aerosols. It includes components to form a fountain of liquid that is being nebulized, a container holder (4), a container (2) with contact medium (3), an additional container (5) with liquid being nebulized (6), a nebulization chamber (7), a system for transporting the aerosol to the user, an outlet duct (11), and a mechanism for regulation of rate of delivery of aerosol. The nebulization chamber (7) is designed as a double-element structure, composed of an intake tube (8) and an expansion chamber (9). In the bottom of the expansion chamber (9) outlets (10) have been made for the drainage of the non-nebulized liquid back to the section of the container remote from the base of the fountain. This reduces the negative action of the non-nebulized liquid on the effectiveness of nebulization. The expansion chamber (9) which is incorporated into the nebulization chamber (7) ensures a significant reduction in coagulation of the aerosol particles, thus increasing the efficiency of the nebulizer and particle uniformity. The latter effect is likewise heightened by this specifically designed outlet duct (10) which accomplishes a process of gravitational filtration. As a consequence of the movement of the stream in the narrow intake tube (8) there is formation of a differential pressure, enabling transport of the aerosol from the nebulization chamber to the user. The above principles are proposed for application to multi-use and single-used devices.

Patent CA-2161860-A1 (CA)
Title: Improved regenerative thermal oxidizer
Inventor: WILHELM FRIEDRICH
IPC: F23G7/06
Filed: 1995-10-31
Abstract: A regenerative thermal oxidizer (RTO) is constructed to receive polluted waste gases from an industrial process, cleanse the gas and permit cleansed gas to exit the RTO to the environment. The RTO includes a lower section (18) having an inlet to receive polluted or incoming gas, and a centrally positioned rotary distributor (20) in the lower section for cooperation in controlling gas flow via a segmented center section. The rotary distributor is substantially smaller than the lower section and is of a substantially smaller cross section. Incoming gas is directed to a middle section segment(s), fills the segment(s) and then flows through a peripheral opening to a segmented upper section (30) where it passes through a heat exchanger (38) to a combustion chamber where it is oxidized or cleansed. From there cleansed gas passes through another upper section segment (40) through a heat exchanger (42) and back to center section segment(s). In the center section the cleansed gas flows to the rotary distributor where it is divided into outgoing and purge gases. The outgoing gas flows through the rotor to a manifold and then to an outlet. The purge gas flows through a purge segment in the rotor to a center discharge pipe. From the pipe the purge gas is directed to a conduit for exiting the RTO and the purge gas is then recycled to the incoming gas to the RTO.

Title: Air baffle for a refrigerator
Inventor: WILLIAMS STEPHEN G
IPC: F25D17/04
Filed: 1995-11-07
Abstract: A refrigerator having a cabinet defining a first compartment and a second compartment separated from each other by a divider wall wherein the divider wall has an air passage for communicating between the first and second compartments. The refrigerator further includes an evaporator disposed in the first compartment, a compressor fluidly connected with the evaporator for moving refrigerant therethrough, and an evaporator fan for moving air over the evaporator. A baffle is positioned within the air passage and is positionable in an open or closed position for selectively opening and closing the air passage. A motor drives a cam which is coupled to the baffle such that rotation of the cam operates to selectively move the baffle to the open or closed position. A thermostat senses temperature within the fresh food compartment. A first switch is operatively associated with the cam for selectively energizing the motor such that the baffle may be moved from the closed position to the open position when the thermostat indicates the fresh food compartment requires cooling. A  second switch is operatively associated with the cam for selectively energizing the motor such that the baffle may be moved from the open position to the closed position when the thermostat indicates the fresh food compartment does not require cooling. The baffle of the present invention further includes a first plate having an aperture therethrough defining an opening through which refrigerated air may pass, and a second plate movable relative to the first plate and including an aperture therethrough defining an opening through which refrigerated air may pass. Both the second plate and first plate aperture includes chamfered edges for forming a sharp edge periphery on the facing plate surfaces such that frost build up on the baffle may be removed by the chamfered edges provided on the periphery of the apertures.

Patent CA-2174328-A1 (CA)
Inventor: NESHEIM MICHAEL E
IPC: G01N33/573
Filed: 1993-11-05
Abstract: A method for assaying body fluid samples containing heparin and a diagnostic kit are described.  Since the reactions go to completion, timing of the assay is not required. The sample is mixed with a heparin-dependent protease inhibitor and either a heparin-independent irreversible inhibitor or a protease substrate.  The coagulation enzyme (protease) is then added in a limiting quantity and it either distributes between the heparin-dependent inhibitor and the heparin-independent irreversible inhibitor, or the heparin-dependent inhibitor and the protease substrate.  The distribution pattern of complex formation of the protease with the two inhibitors or the level of product of the protease-catalyzed hydrolysis of the substrate are used as measures of the heparin activity.  The irreversible inhibitor is a peptidyl chloromethyl ketone and the substrate is a synthetic chromogenic or fluorogenic compound that produces a readily measured signal.
