Patent CA-2349825-C (CA)
Inventor: GARCIA GONZALES JUAN MARIA
IPC: H04Q3/00
Filed: 1999-12-03
Granted: 2009-04-07
Abstract: A method of transmitting signalling information in a telecommunications network between peer user/application parts. Signalling information is transferred from a first user/application part to a Message Transfer Part (MTP) level 3, the information including a destination signalling point identifier identifying the signalling point at which the peer user/application part is located. The MTP level 3 determines from the destination signalling point identifier, a destination address suitable for conveying the signalling information to the destination signalling point.  In the event that the destination address is an Internet Protocol (IP) address and port number, the signalling information and the determined IP address and port number are transferred to an IP part for transmission over an IP network to the destination signalling point.

Title: Double flex seal for tubular connection
Inventor: MALLIS DAVID LLEWELLYN
IPC: F16L15/00
Filed: 2001-08-10
Granted: 2005-11-15
Abstract: A threaded tubular connection has a box member including an internal thread, a pin member including an external thread engageable with the internal thread of the box member, and a protruding sealing surface disposed in the box member such that the pin member flexes radially inward upon passing the protruding sealing surface during make-up. The threaded tubular connection also has a recessed seal cavity disposed in the box member and a reverse angle shoulder at the pin nose that forces the pin member to flex radially outward into the recessed seal cavity of the box member upon final make-up. A method of forming a double flex seal for a tubular connection includes engaging an internal thread of a pin member with an external thread of a box member and flexing a pin nose of the pin member radially inward by passing the pin nose over a protruding sealing surface of the box member during make-up. The method also includes flexing the pin nose radially outward when a reverse angle shoulder of the pin nose comes into contact with a reverse angle shoulder of the box member during make-up and completing the double flex seal by finally making up the connection such that the pin nose of the pin member seats in a recessed seal cavity disposed in the box member.

Abstract: The rotary beater has a number of untwisted, flat, feeding plate segments angularly disposed about its periphery . The plates are arranged in a left-hand group and a right-hand group so oriented that they converge the crop material centrally as they feed and accelerate the crop material rearwardly toward and through the inlet of an axial flow threshing rotor assembly. The feeding segments of each group are arranged in diametrically opposed sets containing at least one segment each, and the sets of one group are offset circumferentially 90° from the sets of the other group. Each segment has a hardened crop-engaging face, and the segments are all detachably bolted to the drum of the beater to facilitate removal and replacement when worn or damaged.

Abstract: A coulter assembly has a resilient spring tine that bears against the compression face of the angled coulter during field operations to remove dirt clumps that otherwise inhibit the furrow-forming action of the coulter. A special spring coil mounting of the tine provides a lively vibratory action as the tine encounters various impact loads from different directions during field operations, thus rendering the tine essentially self cleaning insofar as trash accumulations are concerned. The angle of attack of the tine relative to the ground and the coulter can be readily adjusted without diminishing the vibratory action of the tine.
