Title: Transmission device, in particular, for vehicles and related method for controlling transmission
Inventor: ANTONOV ROUMEN
IPC: F16H61/02
Filed: 1995-08-17
Abstract: The planet gear (9) connected to the input shaft (2a) and a planet carrier (13) connected to the output shaft (18) can be coupled by a clutch (18) operated in clamping by fly-weights (29) and a spring (34) to bring about direct engagement. If clamping is insufficient for torque to be transmitted, the crown wheel (8) slows down and is then immobilized by the free wheel (16).  The device then acts as a reduction gear while the axial thrust (Pap) produced by the helical teeth occurs and releases the clutch (18). The device can also act as a reduction gear, with a piston (44) acting on the housing (20) in the direction which will release the clutch (18) and applying a brake (43) preventing the crown wheel (8) from rotating even in the direction normally permitted by the free wheel (16). The narrow bleed ducts (151, 172) of the chamber (46) associated with the piston (44) and a damping chamber (171) prevent sudden variations in the state of the clutch (18). The transmission device enables operation as a reduction gear, especially when the vehicle engine is used as a brake, is operating at low speed or at high load, while avoiding the shocks produced when the piston is activated or deactivated.

Title: Method and kit for evaluating risk of ovarian cancer in carriers of brc a1 mutation
Inventor: NAROD STEVEN A
IPC: C12Q1/6886
Filed: 1997-02-28
Abstract: The association between the presence of one or more rare (infrequent) alleles of the HRAS variable tandem repeat (VTR) polymorphism and the incidence of ovarian cancer in women who harbor a BRCAl mutation can be used for evaluating risk of ovarian cancer in a human patient.  The patient is tested for the presence of a mutation in the BRCAl gene; and to determine the polymorphic form of the HRASl variable tandem repeat region.  The presence of both a mutation in the BRCAl gene and a rare polymorphic form of the HRASl variable tandem repeat region is indicative of an elevated risk of developing ovarian cancer.  A kit for performing this evaluation includes reagents necessary for performing a test for the BRCAl mutation and to evaluate the polymorphic form of the HRASl variable tandem repeat region.

Title: Downhole lubricator and method
Inventor: MACLEOD ALLAN
IPC: E21B33/068
Filed: 1997-05-28
Abstract: The invention is an assembly which is run into the wellbore to straddle pre-existing control line connections used normally for actuation of a sleeve for a single subsurface safety valve. The lower flapper is closed through the use of one of the control lines. It is then tested against formation pressure to make sure that it holds. Upon determination that the lower flapper is holding, the upper flapper is shut off using the other control line. By adding additional pressure to the control line for the lower sleeve, further movement of the lower sleeve is obtained to urge another sleeve into contact with the upper flapper to provide support for it so that it can be tested from above. Once the two flappers have been tested, uphole assembly in the wellbore can begin through the wellhead in the zone above the tested valves once assembled. Coiled tubing or wireline can be advanced sealingly through the wellhead as the assembly is lowered past the flappers which are now allowed to open. The flapper assembly is eventually removed.

Title: Cap for split press wheel of agricultural vehicle
Inventor: FRIGGSTAD TERRENCE ALAN
IPC: A01B73/00
Filed: 1997-06-02
Abstract: Press wheels are used for rolling over and packing the soil of seed furrows. Split press wheels have an axial gap, and are used when the crop is of the kind that fares best when the soil actually over the seeds is loose. The cap is in two components, which together encircle the split press wheel. When in place, the cap closes thegap, and the split press wheel then functions like a one-piece press wheel. The two components are releasable, being fastened together by bolts. The bolts lie in deformed recesses in the cap, encroaching into the gap, internally of the cap. The act of tightening the bolts stretches the cap over the wheel, whereby the cap grips the wheel, and no mechanical connection to the wheel is required.

IPC: C25C3/20
Filed: 1997-09-22
Abstract: Le procédé selon l'invention apporte une solution au problème de la régulation thermique individuelle des cuves d'électrolyse. Il consiste à agir sur la température de la cuve par l'intermédiaire de la résistance de consigne Ro, qui est modulée de manière à corriger la température à la fois par anticipation et par contre-réaction. D'une part, la correction par anticipation, dite "a priori", tient compte des perturbations connues et quantifiées et permet d'en compenser par avance les effets sur la température de la cuve. D'autre part, la correction par contre-réaction, dite "a posteriori", consiste, à partir de la mesure directe et à intervalles de temps réguliers de la température du bain d'électrolyse, à déterminer une température moyenne corrigée en fonction des opérations périodiques d'exploitation, et à en compenser les variations et les écarts par rapport à la température de consigne. Les corrections sont eftectuées par l'ajustement régulier d'une valeur dite de résistance additionnelle, posifive ou négative, ajoutée à la résistance Ro de consigne de la cuve.
Patent CA-2218772-A1 (CA)
Inventor: WALTER BRUNO
IPC: B06B1/18
Filed: 1997-12-22
Abstract: The invention provide apparatus for shaking structures such as fins in a fluid agitator, shaking screens, walls of bins or hoppers, conveyors, shaking tables, containers and tanks. The apparatus is driven by a hydraulic driving system in which high pressure pulses are generated by repeatedly creating water hammer within a working conduit. This conduit is formed into a loop or a coil and is attached to the member to be vibrated. The working conduit is attached to the driving hydraulic system by flexible connections. This arrangement allows the water hammer to shake vibrated structures directly. Waterhammer generated forces act along the axis of the conduit. By each change of direction of the working conduit water hammer generated force is also changed to correspond with the axis of the working conduit. When working conduit is formed into a coil we can increase number of times that the water hammer generated will act on the workingconduit per one closure of the repeatedly interupting valve.

Title: Spout for particulate material
Inventor: NOTZL ANDREW
IPC: B67B7/86
Filed: 1998-05-28
Abstract: Many major cereal manufacturers currently package their product in cardboard boxes with plastic liners. To get to the product, the cardboard, glued, top flap and the sealed, plastic liner must be opened manually. Existing cardboard and plastic liners typically tear during the opening process resulting in constricted or cumbersome pouring characteristics, and virtually no ability to properly re-seal the packaging to prolong product freshness. The spout of this invention is designed to use the original manufacturers' packaging and gain access to the product by piercing directly through the packaging and into the product. A  sealing surface on the entry stop flange surface and a removable cap provide the ability to properly reseal the container to preserve freshness at virtually the same level as the original product. This spout can be altered slightly in size and rigidity and used to gain access to any small diameter product packaged in a rigid container. i.e.: Powdered laundry/dishwasher detergent in boxes or any small diameter food products packed in boxes.
