Patent CA-2189085-A1 (CA)
Inventor: CORONADO MARTIN P
IPC: E21B33/1295
Filed: 1996-10-29
Abstract: A completion apparatus and method are illustrated to allow the use of an inflatable bridge plug system to be set in lower casing after the open-hole section has been drilled underbalanced. This is coupled  with an assembly to deflate theplug which is run on the bottom of the completion liner. The completion liner is run downhole without having to kill the well to reduce possible formation damage from kill fluids. After the open-hole section is drilled, the plug is run in the hole on coiled tubing and set. Heavy fluids are then circulated above the plug without its being applied to the open-hole formation. The liner the open-hole section is run in the well with a deflation tool, which ultimately engulfs the deflated plug using themechanical support associated  with the plug to facilitate the enveloping procedure. After envelopment, setdown weight releases the anchor for the plug and the assembly is run in the hole with circulation through the plug to facilitate advancement.

Patent CA-2191002-A1 (CA)
Inventor: MILLER JAMES JOSEPH
IPC: C04B18/24
Filed: 1996-11-07
Abstract: In the preparation of building construction products containing cementing agents including portland cement, aluminium or magnesium cements, lime, limestone, silica, gypsum, or clay, cellulose fibers are sometimes added in order to obtain products with reduced density and higher heat insulation value.  The use of cellulose fibers for this purpose often leads to many processing disadvantages and sometimes inferior products.            In the present invention are given methods and formulae for attaching water soluble polycarbohydrate hydrocolloids or gums to cellulose, allowing the preparation of gum-fiber composites or gumfers.  Hydrocolloids are precipitated onto cellulose fibers by means of employing a mineral salt together with an acidulant, under specific conditions of pH and temperature. The gum-fiber composites or gumfers formed have more desirable properties than untreated forms of cellulose and are chemically reactive with cementing agents.  Gumfers may be added to building product formulations at high levels of concentration, resulting in products which have improved properties compared to those made using prior art methods.

Title: Process and imaging a ferroelectric printing form and printing head
Inventor: HIRT ALFRED
IPC: G03G15/05
Filed: 1997-01-17
Abstract: A printing head suitable for imaging a ferroelectric printing form is sealed relative to the printing form by a spring-elastic seal.  In the discharge  chamber  of  the printing head, at a low pressure, preferably less than 10 hPa,  and especially in the presence of a gas with high ionization probability, a  discharge  plasma  is  created, from which charge carriers emerge onto the printing form as  the  result  of  activation  between  electrodes,  with simultaneous  focusing  by  the  application  of  electric and/or magnetic fields between plates.

Title: Swing arm for a motorcycle
Inventor: DESROSIERS DENIS
IPC: B62K25/28
Filed: 1997-02-13
Abstract: A swing arm for customizing the rear wheel of a motorcycle. The swing arm of the present invention is made of a right triangular structure defining a right mounting plane, a left triangular structure defining a left mounting plane, an upper and lower spanner bars joining the forward corners of the right and left triangular structures, and a right arcuated plate joining the right upper and lower corners of the right triangular structure. The right arcuated plate comprises a right pivotal connection along a pivotal axis of the swing arm, and this right pivotal connection is connectable to the frame of the motorcycle. There is further provided a left arcuated plate connected to the upper and lower spanner bars at a distance from the left mounting plane. The left arcuated plate comprises a left pivotal connection along the pivotal axis, and this left pivotal connection is connectable to the frame of the motorcycle. The distance between the left arcuated plate and the left mounting plane is greater than a width of the drive belt driving the rear wheel of the motorcycle, such that when the swing arm of the present invention is adapted to be mounted to the frame of the motorcycle, the drive belt is mountable between the left arcuated plate and the left mounting plane. The displacement of the drive belt toward the left mounting plane provides more space inside the swing arm for installing an oversize tire on the rear wheel.

Patent CA-2201928-A1 (CA)
Title: Negative birefringent rigid rod polymer films
Inventor: CHENG STEPHEN Z D
IPC: C08G69/44
Filed: 1995-10-12
Abstract: A class of soluble polymers having a rigid rod backbone, which when used to cast films, undergo a self-orientation process whereby the polymer backbone becomes more or less aligned parallel to the film surface. This in-plane orientation results in a film that displays negative birefringence. The degree of in-plane orientation and thus, the magnitude of the negative birefringence is controlled by varying the backbone linearity and rigidity of the class of polymers which includes polyesters, polyamides, poly(amide-imides) and poly(ester-imides) through selection of substituents in the polymer backbone chain. By increasing the polymer backbone linearity and rigidity, the degree of in-plane orientation and associated negative birefringence can be increased, and that conversely, by decreasing the polymer backbone linearity and rigidity, the negative birefringence can be decreased.

Title: Bottom discharge arrangement
Inventor: MANSTR M HILDING
IPC: B61D7/24
Filed: 1995-10-31
Abstract: The invention relates to a bottom discharge arrangement (4) intended for mounting on a goods container (2) of a railway truck (1). The arrangement (4) includes at least one pair of flaps (5, 5') which are pivotally mounted on the goods container (2) at their mutually remote edges (6, 6'), so as to be able to swing between an open and a closed position in a plane perpendicular to the edges (6, 6'). The arrangement includes a two-arm lever (17) which is common to the link systems (8, 8') and which functions to maneuver the flaps (5, 5') simultaneously. The lever arm is pivotally mounted centrally at a point located centrally between the pivot axes of the flaps (5, 5') and is pivotally connected at one end to a first link (18) pivotally mounted on one flap (5) and at the other end is pivotally connected to a second link (19) pivotally mounted on the other flap (5'). When the flaps are closed, the pivot points between the parts (17, 18, 19) of the link system (8, 8') lie in an essentially forceless state of equilibrium in a common plane (20) which is locked in this state of equilibrium by means of an operating device (9) coacting with the link system (8, 8'). The operating device (9) functions to apply to the two-arm lever (17) a turning moment around its attachment point so as to bring the link system (8, 8') out of its state of equilibrium and therewith allow the flaps (5, 5') to open.
