Patent CA-2160095-A1 (CA)
Title: Internal mix air atomizing spray nozzle
Inventor: HUFFMAN DAVID C
IPC: B05B7/04
Filed: 1995-10-06
Abstract: The nozzle effects three stages of liquid atomization. The first stage is carried out by means of a single liquid orifice and an expansion chamber containing an impingement pin. A high velocity stream of liquid is discharged through the liquid orifice and is broken-up upon striking the flat end of the im-pingement pin. The second stage is produced by an air guide which reduces in area to form jets of air into a high velocity annular air curtain, the curtain passing through the liquid orifice in surrounding relation with the liquid stream and striking the broken-up flow of the first stage to atomize the particles. The mixture is then allowed to expand in the expansion chamber to reduce the tendency of the liquid particles in the atomized mixture from commingling together and reforming into larger particles. The third stage is effected by the expansion chamber and by multiple dis-charge orifices. The mixture is sprayed from the expansion chamber through the multiple orifices and, upon being discharged into the atmosphere, the parti-cles are atomized further due to the release of pres-sure formed inside the expansion chamber.

Title: Model for gonococcal infection
Inventor: NOWICKI STELLA
IPC: A61K38/00
Filed: 1994-04-07
Abstract: An animal having a disseminated infection with an organism requiring human factor Clq binding for pathogenicity. The animal, preferably a rat, is produced by administration of the organism coated with human factor Clq. The organism is, in particular, Neisseria gonorrhoeae. The rat infected with Clq-coated Neisseria gonorrhoeae provides a model for the disease state. This rat model allows the development and testing of possible prophylactic and therapeutic agents for the disease and is particularly useful as a model for the advanced stages of gonococcal infection in females.  Prophylactic or therapeutic compositions including antibodies or Neisseria gonorrhoeae peptides with binding specificity for human factor Clq are described. A Clq synthetic analog having binding specificity for N. gonorrhoeae and without binding specificity for eukaryotic cells is described as being useful to treat gonoccocal infection.

Patent CA-2164098-A1 (CA)
Title: Splicing aged optical fibers
Inventor: LJUNGQVIST GOERAN
IPC: G02B6/25
Filed: 1995-03-30
Abstract: For improving mechanical characteristics of a segment of an aged optical glass fiber, the segment is retained between clamps, e.g. in a conventional splicing machine.  Then the segment is heated to a high temperature in the vicinity of the softening temperature or melt temperature of the glass material of the fiber by means of an infrared light beam from a carbon dioxide laser or by an electric arc generated between the welding electrodes.  In particular, the tensile strength is increased considerably by this procedure, what allows that the heated segment can be handled and exposed to the operative steps required for splicing the fiber to another optical fiber.  Then also old fibers arranged in the ground can be repaired and spliced, and it is not necessary to replace whole lengths of old fibers.

Title: Downhole gas separator
Inventor: MCCOY JAMES N
IPC: E21B43/38
Filed: 1995-11-30
Abstract: A downhole gas separator is connected to the lower end of a tubing string. The separator includes a tubular body which has a decentralizer mounted to one side for driving the opposite side of the separator against an interior wall of the casing. This creates a narrow flow zone between the separator body and the adjacent casing wall and a wider flow zone on the decentralizer side of the body. A fluid inlet is provided on the side of the gas separator tubular body facing the narrow flow zone. The fluid in the narrow flow zone has a substantially higher concentration of liquid than the fluid in the wider flow zone. Fluid, primarily liquid, flows through the fluid inlet into a chamber within the separator. A diptube transfers the fluid from the separator chamber to the pump.

Patent CA-2186174-A1 (CA)
Title: Internal combustion engine
Inventor: HAZEN DAVID J
IPC: F01L1/24
Filed: 1996-09-23
Abstract: A rocker arm for an internal combustion engine is provided with a hydraulic lash adjuster located therein. The rocker arm comprises two portions rotatably mounted relative to each other with the hydraulic lash adjuster located therebetween. The hydraulic lash adjuster compensates for any slack in the valve train and rotates with the rocker arm about the rocker arm's axis of rotation rather than move linearly along the pushrod axis as in prior art systems. As a result, hydraulic lash adjuster wear, valve spring force, engine friction, and fuel consumption may be reduced while not decreasing the valve train toss speed.
