Patent CA-2266500-A1 (CA)
Title: Conduit connector and method
Inventor: RIDENOUR RALPH G
IPC: F16L13/14
Filed: 1997-10-03
Abstract: A conduit connection joint is formed to connect a tube (10) and afitting body (12) in fluid tight relation. The joint is made by axially compressing the tube (10) in a bore (14) in the fitting body (12) so as to cause formation of a first bead (52) in a bead formation area.  Further axial compression of the tube (10) causes the sequential formation of an additional bead (54) in the bore (14) so as to provide engagement between the tube (10) and the fitting body (12). The engagement of the fitting body (12) and the tube (10) may be further strengthened by axially compressing and radially expanding the beads (52, 54).

IPC: H04L12/18
Filed: 1997-11-07
Abstract: Multiparty communications are handled in a digital device according to a data structure where a formatted packet from a particular transmitter is translated into a shared format M which is then retranslated to various destinations.  Handling of group address packets can be accomplished with customized circuitry. Flexibility is achieved by allowing parameters of the routing routine to be specified in memory which can be programmably altered. In a specific embodiment, the representation of a group is a circular linked list.  Each party has one entry in the linked list, therefore the entire structure has N substructures for N participants.

Title: Bulldozer/pipelayer combination
Inventor: FORSYTH RAYMOND
IPC: B60P1/54
Filed: 1999-10-18
Abstract: A combination bulldozer and pipelayer includes a front mounted blade, or scoop, and a side mounted pipelayer attachment. When operated as a bulldozer, a pair of endless track roller frames are free to oscillate up and down about a horizontal axis passing through the bulldozer's main frame for improved traction and grading characteristics, reduced stress on the tractor structure, and a more comfortable ride for the operator. When operated in the pipelayer mode, the track roller frames are locked in fixed position to the vehicle's main frame to provide a stable platform for lifting and transporting a heavy load such as sections of pipe. The side mounted pipelayer attachment includes a folding boom which can be stowed in a retracted position or extended to the use position by the operator using only the boom and load controls. The bulldozer's hydraulic system is connected in series to the pipelayer's hydraulic system to permit operation of the pipelayer boom and load winches at the same speed for improved load control without stalling the heavier loaded winch drum. Also provided is a quick load release arrangement for allowing a toad to free-fall to the ground in the event of an unstable condition in lifting the load.
