Patent CA-2082473-A1 (CA)
Title: Sulphate removal process
Inventor: OLMSTEAD DOUGLAS E
IPC: C01B11/14
Filed: 1992-11-09
Abstract: ABSTRACT OF THE INVENTION          This invention relates to an apparatus and process for selectively precipitating crystalline sodium sulphate from a mother liquor, the mother liquor being an aqueous solution of sodium chlorate and sodium chloride, and containing dissolved sodium sulphate.  The process includes diluting the mother liquor with demineralized water thus forming a diluted liquor.  The diluted liquor is then chilled to a temperature Tx thereby forming a sodium sulphate crystalline precipitant, where Tx is in the range between the saturation temperature of sodium chlorate in the diluted liquor Tc and the saturation temperature of sodium sulphate in the diluted liquor Ts.  The sodium sulphate crystalline precipitant is separated, through settling for example, from a resultant clarified liquor.
Patent CA-2088084-A1 (CA)
Inventor: D AMBROGIO WILLIAM J
IPC: H04Q11/04
Filed: 1993-01-26
Abstract: A method for effecting bandwidth-on-demand, multiple digital channel connections between network subscribers, wherein each of a series of call requests from a given network subscriber to a given recipient establishes a connection via a restricted tandem switching arrangement. The switches within the network facilitating this method are each programmed to utilize inter- switch paths having essentially equivalent electrical delays when effecting connections for calls dialed by network subscribers designated as bandwidth-on-demand users, resulting the virtual elimination of inter-channel differential path delays.

Le mélangeur (37) peut être alimenté à partir du duplicateur de signaux de radiofréquences (32, 33, 34) ayant une entrée (25) couplée à une source du spectre, une première sortie pour un spectre dupliqué par le duplicateur connectée à une entrée (35) du mélangeur, et une seconde sortie destinée à l'autre spectre dupliqué par le duplicateur et connectée à l'autre entrée (36) du mélangeur. Dans une variante, le mélangeur de radiofréquences (37) peut recevoir la sortie d'un générateur de bruits à large bande (68) à son autre entrée (36, fig. 5). Une combinaison d'une multiplicité de radiofréquences distinctes et instantanées indicatrices du spectre ou de l'arc (12) est détectée, par exemple avec un détecteur de combinaison de fréquences (42) dont une entrée (40) est couplée à la sortie (38) du mélangeur de radiofréquences.

Title: Four-cycle engine
Inventor: TAMBA SHINICHI
IPC: F02B75/02
Filed: 1993-04-19
Abstract: There is disclosed a four-cycle engine in which a crankshaft and a cam shaft are disposed generally parallel to each other, and an intake port and an exhaust port are formed in a cylinder head.  The intake port and the exhaust port are arranged in such a manner that a line passing through the centers of the intake port and the exhaust port is non-parallel to the axis of the crankshaft.  With this arrangement, an intake passage and an exhaust passage can be greatly shortened, and therefore an intake efficiency as well as an exhaust efficiency can be enhanced, thereby enhancing the performance of the engine.  In an air-cooled engine, the overheating of the engine is greatly restrained.

Patent CA-2098716-A1 (CA)
Inventor: MEHRA RAHUL
IPC: A61N1/365
Filed: 1991-11-13
Abstract: A method and apparatus for sensing in vivo blood pressure proportional to the left ventricular pressure for detecting ventricular tachyarrhythmias or the cardiovascular status in congestive heart failure, and/or for adjusting the rate of a pacemaker. A lead (76) with a pressure sensor (118) near its distal end is placed transvenously through the coronary sinus and located in the coronary vein. When in place, a bulge or an inflatable balloon proximal to the pressure sensor may be used to acutely occlude the coronary vein (80) until the sensor fibroses in. The balloon may be reinflated prior to pressure measurements. The pressure that is sensed in that location is proportional to the left ventricular pressure. Values representing the left ventricular pulse, systolic and diastolic pressures, as well as the differentiated rate of change (i.e., dP/dt), gross rate of change (.delta.P/.delta.t) and mean or average of such pressure values are all or selectively developed by sofware algorithms and implemented in microprocessor based control circuitry.

Title: Refrigerant filter-drier for use in a refrigerant recycling device
Inventor: ROSEN SHELVIN
IPC: F25B43/00
Filed: 1993-07-23
Abstract: REFRIGERANT FILTER DRIER FOR USE IN    A REFRIGERANT RECYCLING DEVICE                 Abstract of the Disclosure A light-weight, readily replaceable filter-drier for use in a refrigerant recycling device comprising a long, narrow body containing a closely packed desiccant material that substantially occupies the entire volume of the body.  the desiccant may be comprised of 100 percent molecular sieve or any combination of desiccants and/or other absorbent materials that are required to achieve the desired degree of refrigerant purity.  Filters are located at either end of the body which are biased by a spring member support and contain the desiccant material within the body.  Standard fluid fittings close the ends of the filter-drier and enable the device to be easily and quickly installed and removed in the refrigerant recycling device. The present invention achieves the advantage of dramatically improving the efficiency and capacity of a filter-drier for use in a recycling device by substantially increasing the amount and duration of contact between the desiccant and the refrigerant.  In a preferred configuration, multiple filter-driers are connected in series and have a moisture indicator located therebetween. Not only does a multiple filter-drier set-up increase total dehydration capacity and efficiency, but also it allows each individual filter-drier to be used to a greater capacity while still maintaining a factor of safety.
