Patent CA-2344154-C (CA)
Inventor: VON GYNZ-REKOWSKI GUNTHER
IPC: E21B4/02
Filed: 1999-09-29
Granted: 2006-07-25
Abstract: A lubricant cooling system for a sealed bearing section used in drilling with downhole motors comprises a radial bearing or bearings (38, 40) which preferably contain internal (56, 58) and external (46, 48) spiral grooves such that rotation of the central hollow shaft (10) which supports the drillbit forces lubricant (31) up the external grooves toward the upper seal (22) and then back down in the internal grooves along the cooled hollow shaft which has drilling mud flowing through it. Similarly, the rotation of the hollow shaft forces lubricant through an internal spiral in a lower radial bearing or bearings until it reaches the lower seal (30) at which time it is forced into the external spirals past the thrust bearings in the bearing section. This axial circulation effect allows the removal of heat efficiently from the lubricant by virtue of circulating drilling mud in the hollow shaft and in the outer annulus returning to the surface. The bearing section operating life is thus extended many hours because the lubricant attains a more uniform temperature throughout.

Title: Method of cutting insulation for a pipe elbow
Inventor: KASPERSION EDWARD
IPC: B26D3/10
Filed: 2001-05-11
Granted: 2008-02-05
Abstract: An insulation piece for joining with a similar piece to surround a pipe elbow of a larger diameter such as greater than 9 inches outside diameter is formed by cutting from a block of the insulation material. This is effected by providing an outer and an inner arcuate blade portion each extending around an angle of greater than 180 degrees and mounted on a holder so as to rigidly carry the arcuate blade portions substantially in a common plane and centered about a common center; providing a table surface at right angles to the plane and containing the center; oscillating the holder and the arcuate blade portions thereon about an axis at right angles to the common plane and passing through the center such that the blade portions of the ring members are exposed above the table plane and reciprocate about the axis in a cutting action; and guiding the movement of the block in a part circular path about a guide axis at right angles to the table plane with the guide axis located so that the blade portions cut through the block each along a part circular line at a radius of curvature from the guide axis arranged to match a respective radius of curvature of the pipe elbow. The blades are each cut from a plate integrally with a holder portion to form a complete closed rigid body and have carbide tips mounted in notches in one edge so that the blades retain a circular shape during cutting.

Abstract: The friction brake is provided with a brake lining. The support plate (1) of said brake lining is provided with a friction lining (2). Two resonators (3) which are diagonally displaced against each other are formed in the material of the support plate (1). The natural frequency of the resonators (3) is adjusted to the friction induced excitation frequency of the support plate (1). The surfaces of the resonators (3) are dimensioned in such a way that the sound waves thus generated lie beyond the human hearing range. The resonators (3) use the vibration energy which is supplied to the support plate (1) without causing audible noises. Hence, the brake is acoustically attenuated.

Abstract: A method of interfacing, and an interface for use, between two IPv6 domains separated by an IPv4 domain. The interface comprises a protocol converter, an encapsulator/un-encapsulator and a controller. When an IPv6 source wishes to send to a named destination in the other IPv6 domain, the source sends a normal IPv6 address request to its local DNS server, which relays it to an IPv6 name server in the other IPv6 domain. The response message, containing the true IPv6 address of the destination is received at the remote interface, which appends to the resulting protocol converted DNS response message a first additional record containing the true IPv6 address, and a second additional record containing the IPv4 address of that interface. Upon receipt at the other interface, the additional records are stripped off, their contents stored in an entry of a table, and the true IPv6 address written into the address record of the resulting IPv6 DNS  response message. When the interface receives a packet from an IPv6 host, it checks whether the destination address matches an entry of its table, and if so sends the packet to the encapsulator together with the IPv4 address of the remote interface. The remote interface extracts the source address and the address of the encapsulating interface and stores these in an entry in its corresponding table for use in encapsulating return packets to the source. If, however, the destination address is recognised as being of IPv4-compatible or IPv4-mapped format, the packet is sent to a protocol converter.

Abstract: In one aspect of the invention, tools are actuated or operated within a well by selectively expanding the tool wall. To actuate the tool, the tool wall (225) is urged outward past its elastic limits. The expanding wall physically unlocks a locking ring (280) which then ulocks a piston (260). Thereafter, hydraulic pressure difference are employed to move the piston to operate the down-hole tool. In another aspect of the invention, a first piece of casing is joined to a second, larger diameter casing. By expanding the diameter of the first piece of casing into contact with the second piece of casing, the two are joined together.  The joint is formed with helical formations in a manner that provides flow paths around the intersection of the two members for the passage of cement or other fluid.
