Patent CA-2243886-A1 (CA)
Inventor: FORREST LINDSAY WARREN
IPC: C10L1/00
Filed: 1998-07-27
Abstract: In a first aspect petrol is treated by subjecting it to a plurality of magnetic fields of field strength up to 4000 gauss in rapid succession. This treatment is believed to improve vehicle performance due to improved atomisation of the fuel.   In the second aspect a fuel is treated by removing water from the fuel and then subjecting the fuel to one or more magnetic field. Removal of water from the fuel prior to magnetic treatment results in improved engine performance.   In a third aspect fuel stored within a container is periodically circulated through a magnetic treatment apparatus by a pump under the operation of a timer.

Title: Use of the green fluorescent protein as a screenable marker for plant transformation
Inventor: GORDON-KAMM WILLIAM
IPC: C12N15/82
Filed: 1997-05-01
Abstract: A method for the production of transgenic plants is provided in which a vector carrying a gene encoding the green fluorescent protein is introduced into cells, the cells are screened for the protein and transformed cells are selected and regenerated. The cellular toxicity of the green fluorescent protein is circumvented by regulating expression of the gene encoding the protein or directing the protein to a subcellular compartment where it is not toxic to the cell. DNA constructs are provided for cell transformation in which the expression of a gene encoding the green fluorescent protein is placed under the control of an inducible promoter. In addition, DNA constructs are provided in which a nucleotide sequence encoding the green fluorescent protein is operably linked to a signal sequence which directs the expressed protein to a subcellular compartment where the protein is not toxic to the cell. Oxidative stress to plant cells transformed with GFP also can be ameliorated by transforming cells with an expression vector comprising genes encoding GFP and an oxygen scavenger enzyme such as superoxide dismutase. The toxicity of GFP in transformed plants can be eliminated by excising the screenable marker gene following detection of transformed cells or sectors. The FLP/FRT system is used in conjunction with GFP as a visible marker for transformation and FRT excision. A nucleotide sequence optimized for expression of the green fluorescent protein in plants is also provided.

Patent CA-2253757-A1 (CA)
Title: Self-adjusting down-article indicator for a packaging machine
Inventor: FETTERS SHAWN M
IPC: B65B59/02
Filed: 1997-05-29
Abstract: A down-article indicator (10) which automatically adjusts for the height difference of articles, such as bottles (90), when article size is changed for a new run on a machine (96) conveying articles. A pivotably mounted height sensing arm (20), located on one lane of the machine, downstream from an array of freely pivoting detecting arms (40), is connected by an adjustable mechanical linkage (70) to a pivoting bracket (62) holding a retro-reflective photo eye (61) in proper location with respect to the detecting arms so that the detecting arms do not break a light beam from the photo eye during normal operation. A non-upright article (92) will cause a detecting arm to pivot and break the light beam to stop the machine. As a new group of articles having a different height moves into the down-article indicating station, the height sensing arm automatically moves the photo eye to its proper location for the new height articles. The machine has a "prime" mode which overrides a stop signal which may be sent by the photo eye while the transition between groups of articles passes through the machine.

Title: Marine propulsion system
Inventor: RINZAKI SHOICHI
IPC: B63H20/14
Filed: 1998-11-12
Abstract: In a marine propulsion system comprising: a drive shaft operably connected to an engine and carrying a drive bevel gear; a propeller shaft carrying a propeller; and a pair of driven bevel gears meshing with the drive bevel gear and selectively engageable with the propeller shaft via a clutch member, the propeller shaft is provided with an axially facing annular shoulder surface which faces a corresponding axially facing surface of one of the pair of driven bevel gears to determine an axial position of the propeller shaft, and a rolling thrust bearing is disposed between the mutually facing surfaces of the propeller shaft and the one of the pair of driven bevel gears. The rolling thrust bearing reduces the friction between the mutually facing surfaces of the propeller shaft and the one of the driven bevel gears when they rotate in the opposite directions to each other, to thereby improve the durability of these component parts.

Title: Side frame-bolster interface for railcar truck assembly
Inventor: HAWTHORNE V TERREY
IPC: B61F5/12
Filed: 1999-06-25
Abstract: An interface between the end of a bolster and a side frame column for a three-piece railcar truck assembly is disclosed. The bolster and side frame have several pairs of facing stop surfaces at the interface. Each pair of facing stop surfaces are at two different spacings: one spacing is close, with a small gap between the stop surfaces; another spacing is greater than the first. The second spacing allows the side frame to pitch with respect to the bolster transverse axis. The bolster stop surfaces may be the lands inboard and outboard of the friction shoe pockets. The lands may be shaped so that there is a raised warp control portion or surface and one or more relief portions or surfaces, the warp control portion extending farther laterally than the relief portions. The warp control portion is used to maintain the truck in a square relationship, and the more loosely spaced relief portions allow for side frame articulation as the truck traverses track at different elevations. The raised warp control portions and reliefs may alternatively or also be formed on the side frame lands or wear plates.
