Patent CA-2118555-A1 (CA)
Inventor: KOBAYASHI MASAKI
IPC: B60R1/06
Filed: 1994-03-08
Abstract: The mirror system has devices for adjusting the reflectivities of the interior and exterior rearview mirrors to different values to correct the driver's unbalanced rearview visibility. These devices include, for instance, a liquid-phase ECD (Electrochromic Device) used in the interior rearview mirror and a solid-state ECD used in the exterior rearview mirror so that appropriate reflectivities of the two mirrors can be obtained, even if they experience the same operation conditions. When the same-type ECD is used for both interior and exterior rearview mirrors, the drive voltage for the exterior rearview mirror is made lower than that for interior rearview mirror to make the latter's reflectivity smaller than the former's. For this purpose, transforming circuits are provided as well as terminal voltage sensing and controlling circuits.

Title: Virus resistant plants
Inventor: EDINGTON BRENT V
IPC: A01H5/00
Filed: 1993-05-06
Abstract: The invention features a responsive RNA molecule which encodes, in one or more protein-coding regions, a polypeptide, and which includes a regulatory domain, a substrate region, and a ribosome recognition sequence. This responsive RNA molecule has an inhibitor region in the regulatory domain, which regulatory domain is complementary to both a substrate region of the responsive RNA  molecule and to an anti-inhibitor region of a signal nucleic acid such that, in the absence of the signal nucleic acid, the inhibitor and substrate regions form a base-paired domain the formation of which reduces the level of translation of one of the protein-coding regions in the responsive RNA molecule compared to the level of translation of that one protein-coding region observed in the presence of the signal nucleic acid. The anti-inhibitor region of the signal nucleic acid is complementary in sequence to the inhibitor region of the responsive RNA molecule such that when the anti-inhibitor region is base-paired with the inhibitor region, translation of one protein-coding region of the responsive RNA is increased compared to the level of translation of that protein-coding region observed in the absence of the signal nucleic acid. The signal nucleic acid comprises part of the nucleic acid of a plant cell infecting organism.

Title: Semiconductor memory apparatus
Inventor: MARUMOTO KYOJI
IPC: G06F12/16
Filed: 1994-12-02
Abstract: A semiconductor memory incorporates a protecting circuit which causes data stored in a memory portion to be outputted by executing a key canceling sequence from an external apparatus.          The data stored in the memory are not outputted only when a key canceling  signal  is  inputted to the protecting circuit  to execute the key canceling sequence, so that the data are not outputted only by inputting an address signal and a reading signal to the memory apparatus.  As a result, it is impossible to find out the contents of the program stored in the memory portion.

Patent CA-2137573-A1 (CA)
Title: Pharmaceutical compositions containing nsaid and bile acids
Inventor: BARNWELL STEPHEN GEORGE
IPC: A61K9/48
Filed: 1993-06-11
Abstract: Non-steroidal anti-inflammatory drugs, such as indomethacin, and other pharmaceutically active compounds, are formulated with bile acids or their salts and conjugates. Bile acids previously proposed for use in such formulations have placed an un-acceptable toxic load on the liver and/or cells of the gastrointestinal tract, causing abnormal liver function or cell erosion. In this invention, the bile acid is a low detergent bile acid, such as ursodeoxycholate. Stabilization of the bile acid pool results in enhanced and predictable enterohepatic recycling of NSAIDs (and other drugs) and a reduced risk of toxicity.

Title: Manufacture of ferric sulfate and hydrochloric acid from ferrous chloride
Inventor: CONNOLLY DAVID W
IPC: C01B7/03
Filed: 1995-02-28
Abstract: A two step method of converting ferrous chloride from a pickling liquor to produce hydrochloric acid and ferric sulfate is disclosed. The ferrous chloride is first mixed with sulfuric acid to produce ferrous sulfate and HCl. The HCl is carried to an absorbtion tower where most of the HCl is collected and the remainder is returned to the reactor. The ferrous sulfate is separated from the sulfuric acid. The unreacted sulfuric acid is returned to the reactor and the ferrous sulfate is transported to a second reactor where it is reacted with sulfuric acid and air (O2) to produce ferric sulfate. The ferric sulfate is removed from the second reactor. Both reactions are carried out at relatively low temperatures under atmospheric pressures.
Patent CA-2144825-A1 (CA)
Title: Method of bleaching cellulose pulp
Inventor: HENRICSON KAJ
IPC: D21C9/10
Filed: 1995-03-16
Abstract: A method of producing TCF-pulp using an ozone stage (Z) as part of the bleaching sequence does not require cooling of the pulp prior to the Z stage, and then subsequent heating of the pulp after the Z stage, since the Z stage is practiced at medium consistency and at about the same temperature as the other bleaching stages (i.e. between about 80-120°C). Chemical (or other)cellulose pulp is treated by the steps of: (a) effecting acidification, washing or pressing, oxygen delignification, peroxide bleaching, or chelation of chemical cellulose pulp at a temperature between about 80-120°C; (b) immediately after step (a), ozone bleaching the pulp at a consistency of about 8-20% at a stabilized pH of about 2-7 and at a temperature between just over 80°C and about 120°C (preferably about 90-100°C), for less than about one minute (typically less than 30 seconds); and (c) immediately after step (b) effecting acidification, washing or pressing, oxygen delignification, peroxide bleaching, or chelation of the pulp at a temperature between about 80-120°C. The pulp pH is preferably stabilized by holding the pulp in liquid at a pH between about 2-5 for at least five to ten seconds (preferably 20 seconds-100 minutes) prior to the addition of ozone to the pulp in the Z stage.
