Patent CA-2096457-A1 (CA)
Title: Air/Fuel Ratio Control
Inventor: STUEVEN JEFFREY S
IPC: F02B77/08
Filed: 1993-05-18
Abstract: A system for controlling the air/fuel ratio input to a small engine  measures the oxygen level in the engine's exhaust and compares it with a reference level. A stepper motor controls the air/fuel ratio and it is advanced one step each time a clock pulse is produced in a direction determined by the level of exhaust oxygen.  A fault detector circuit stops the engine if the sensed oxygen level is outside a preset range for more than a preset time interval.
Patent CA-2099026-A1 (CA)
Inventor: BLACKLEDGE JOHN W JR
IPC: G06F21/86
Filed: 1993-06-23
Abstract: This invention relates to personal  computer  systems  and, more particularly, to such a system having security features enabling control over access to data retained in such a system.  This invention contemplates protecting a personal computer system which has  the  capability  of  becoming  a secure system from being placed into that condition by an attack on an unsecured machine. Additionally, in a network environment,  it is important to maintain network security that any given particular system be uniquely identified to the network, in order to guard against the substitution of an insecure  "alternate"  which would open the network to attack  through   an   insecure   system.    This invention contemplates provision for such identification in a secure manner.

Patent CA-2104235-A1 (CA)
Title: Waste valve fittings
Inventor: COLE ALAN C
IPC: E03C1/298
Filed: 1992-02-20
Abstract: A waste outlet fitting (1) has a tubular body (2) in which a cartridge (3) is mounted. An elastomeric diaphragm (6) is carried by a central support member (4) integral with the cartridge and defines a skirt flaring outwardly to normally close the bore of the cartridge (25) and thus the tubular body (2). Part of the cartridge wall may be elastomeric for improved sealing with the diaphragm (6). Pressure of water leaving a basin via the outlet fitting (1) causes the diaphragm to deflect downwardly and inwardly allowing water to pass. When the basin is empty the diaphragm (6) returns to its original position under its own resilience, thus sealing the outlet from any back flow.
Patent CA-2104502-A1 (CA)
Inventor: HORN JOANNE M
IPC: C02F3/12
Filed: 1993-08-20
Abstract: ABSTRACT         Mercury, in its divalent cationic form [Hg (II)], is extremely toxic due to its ability to bind sulfhydryl, thioether and imidazole groups and thereby inactivate enzymes.  Organic species of mercury are capable of accumulating in the tissues of higher organisms causing systemic diseases.  Despite the toxicity of mercury, mercury containing compounds continue to be discharged into the biosphere.  The present invention offers a solution to this problem by providing Pseudomonas Putida strains with heightened mercurial detoxification properties by constitu-tive hyperexpression of the merTPAB genes.  The invention also genetically combines the ability to reduce Hg at increased rates under conditions of high concentration, with a benzene degrada-tive pathway.  Derivative Pseudomonas Putida strains are thus able to dissociate the chemically dissimilar components of an organomercurial compound, phenylmercuric acetate (PMA) into its metal and aromatic elements, and separately detoxify each.          Characterization of these isolates shows that they have potential for treatment of Hg-containing pollutants.

Title: Method for regaining mud circulation in operating well and device for its embodiment
Inventor: EFIMKIN ALEXEI A
IPC: E21B41/00
Filed: 1992-12-01
Abstract: Run into a well, e.g. in a tubing (1), on a pipe string (2) is a hydromechanical cleaner (3). A bridge (4) is washed out by direct descending flow of drilling mud pumped through the pipe string (2). The cleaner (3) is moved downward as the bridge (4) is washed out by moving the pipe string (2). The ascending flow of drilling mud rotates the cleaning heads (5 and 6) in opposite directions. Cutting knives (7) of the cleaning heads (5 and 6) mechanically remove deposits from walls of the tubing (1). The deposits from the walls are removed mechanically during running the cleaner (3) into the well and curing its lifting from the well. Products of the washed out bridge (4) and deposits are removed from the well by ascending flow through a side branch pipe (41) of a wellhead circulating head (18). The device for use in the method includes also a mechanism for moving the pipe string (2) and a pump unit.
