Title: Wrapping device for large round baler including holder for spare roll of web wrapping material
Inventor: PHILLIPS KENNETH CRAIG
IPC: A01F15/07
Filed: 1998-07-28
Abstract: A large round baler is equipped with a device for wrapping bales with a web of net wrapping material. The device includes structure for supporting a spare supply roll of wrapping material a short distance vertically above a zone for containing an active supply roll of wrapping material. The structure for supporting the spare roll is selectively movable to a non-use position for permitting a pressure-applying roller, that normally engages the active supply roll of wrapping material, to be swung vertically out of the way so as to permit the spare supply roll to be moved into place as the active supply roll once the latter is depleted. A pair of retractable loading supports are provided for supporting the spare supply roll at a location reawardly of the zone prior to moving the spare roll into the zone to take the place of the depleted active supply roll. A net guide roll has one end mounted for being selectively lifted to permit easier threading of a length of net that has been pulled from the spare supply roll when the latter is located on the loading supports.

Patent CA-2246835-A1 (CA)
Title: Remote brake application valve
Inventor: SICH GARY M
IPC: B60T15/42
Filed: 1998-09-08
Abstract: The present invention is a valve system for exhausting air from a brakepipe in a remote portion of a train. It has a pressure containment structure having a cylindrical bore and a piston mounted in the bore. A first valve chamber is on one side of the piston and a second valve chamber on a second side.     A diaphragm seals between piston and bore, the diaphragm having an annular fold for permitting movement of the piston within the bore. The system has a first brakekpipe pressure passageway for conveying air from the brakepipe to the first valve chamber and a control pressure connection for conveying air from a control chamber to the second valve chamber. A biasing means is provided for urging the piston toward the first valve chamber. A brakepipe exhaust valve connected to the piston is closed when the piston is moved toward the first valve chamber and opened when the piston is moved toward the second valve chamber so that when the pressure in the control chamber is reduced the brakepipe exhaust valve is opened and air is vented from the brakepipe. An annular sleeve is attached to the pressure containment structure and protrudes into the fold of the diaphragm to prevent the diaphragm from inverting if the pressure in the brakepipe drops below the pressure in the control chamber when the piston is positioned toward the first valve chamber.

Patent CA-2252944-A1 (CA)
Inventor: CUMMINS DAVID P J
IPC: E21B21/06
Filed: 1997-05-05
Abstract: This invention provides a fluid-handling system for use in underbalanced drilling operations. The system includes a first vessel which acts as a four phase separator. The first vessel includes a first stage for separating solids. Oil and gas are separated at a second stage. A pressure sensor provides signals to a pressure controller, which modulates a gas flow valve coupled to the vessel for discharging gas from the first vessel. The pressure controller maintains the pressure in the first vessel at a predetermined value. An oil level sensor placed in the first vessel provides a signal to an oil level controller. The oil level controller modulates an oil flow valve coupled to the vessel to discharge oil from the first vessel into a second vessel. Water is discharged into a third vessel. Water from the third vessel is discharged via a water flow control valve, which is modulated by a level controller as a function of the water level in the third vessel. Any gas in the third vessel is discharged by modulating a gas control valve as a function of the pressure in the third vessel. In an alternative embodiment, a central control unit or circuit is utilized to control the operations of all the flow valves. During operations, a control unit maintains the pressure and the levels of the fluids in such vessels at their respective predetermined values according to programmed instructions. The fluid-handling system also controls the wellbore pressure as a function of downhole-measured parameters and the drilling fluid mix as a function of selected operating parameters.

Title: Expansion joint and seal containing intersections
Inventor: BRAUN FRANK A
IPC: E01C11/12
Filed: 1998-11-09
Abstract: An expansion joint and seal for an expansion joint for use in structures where the joint has an intersection uses a seal with a solid thick keel extending along a lower edge of a central portion in an area of the intersection. The keel commences in a transition area between a conventional seal and the intersection. The seal increases in depth as the intersection is approached until it reaches a maximum depth at a mid point of the intersection. The keel minimizes distortion from racking during expansion or contraction of the joint. The seal is shaped to enable debris to be easily removed.
Patent CA-2255768-A1 (CA)
Inventor: GERTMAR LARS
IPC: H01F27/00
Filed: 1997-05-27
Abstract: In a plant comprising one or more electric machines constructed with insulated conductors and connected for heavy current via insulated conductors, the magnetic circuit in at least one of these electric machines is connected directly to a high supply voltage of 20 - 800 kV, preferably higher than 36 kV. The insulation of the electric machine is built up of a cable (6) placed in its winding and comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by outer and inner semiconducting layers (34, 32) and intermediate insulating layers (33). The conductors (31) may be group-wise connected in parallel and semiconducting layers are therefore not required around every conductor in the group. If the conductors (31) are connected in series with each other within the group a part insulation (35) is required which will withstand a few kV, whereas connection of the conductors (31) to every phase requires a strong part insulation (35) which will withstand the phase voltage of the high-voltage supply network.

Inventor: HORNBUCKLE WILLIAM I
IPC: G01V1/30
Filed: 1997-05-15
Abstract: The invention relates to a method of presentation and interpretation of three-dimensional seismic data (90). In particular, the invention relates to a method and apparatus for identifying volumetric subterranean regions bounded by a surface in which a specific seismic characteristic has a constant value. In one embodiment, three-dimensional seismic data (90) for a subterranean volume (60) is provided as input to a computer program (94) for performing "isosurface" processing of the data (90). This results in a graphical representation (Figure 5) of three-dimensional sub-volumes (60, 70) whose boundaries are defined by surfaces (62, 64) in which a specific seismic characteristic has constant value.

Title: Safe-and-quick-pouring bottle
Inventor: BARDHAN BIBHUTI BHUSAN
IPC: B65D53/08
Filed: 1999-02-17
Abstract: This is a bottle with a peelable sealing foil at the main opening. This peelable foil has a long tail or thread attached to one edge. Thus, the bottle can firstly be safely tilted into the opening where its contents have to be emptied without spilling the contents outside, and then the said tail or thread can be pulled for the bottle to be opened remotely and emptied safely. Instead of the said peelable sealing foil, the bottle may have a snap-on cap with a tongue so that it can be opened remotely by pressure on a depression on this tongue with a stick. This bottle also has at the other end (that is, at the bottom) a second opening that has a cap that can be opened, say by unscrewing, to let the air in once the main opening is ready for pouring; thus the contents flow out safely, easily and quickly.

Title: Central vacuum hose dispenser
Inventor: GOSSELIN TILMON JOSEPH PAUL
IPC: A47L9/00
Filed: 1999-02-22
Abstract: In a first aspect of the invention, there is provided an apparatus for storing and dispensing a vacuum hose of a central vacuum system. The apparatus comprises a base frame, a basket pivotally mounted on a thrust bearing affixed to the base frame, and a conduit rigidly held above the basket relative to the base frame and extending along the pivotal axis of the basket. When a vacuum hose is inserted downward inside the conduit and into the basket, the weight and resiliency of the hose causes the basket to rotate for coiling the hose therein without twisting it. The hose is thereby neatly stowable between uses. In another aspect, the base frame and the basket are installed beneath the floor of a house and the conduit extends upwardly into a wall cabinet above the main floor of the house and near a vacuum inlet socket of the central vacuum system.
