Patent CA-2197768-A1 (CA)
Inventor: SILVERMAN DAVID L
IPC: G06Q40/04
Filed: 1995-08-17
Abstract: A negotiated matching system includes a plurality of remote terminals associated with respective potential counterparties, a communications network for permitting communication between remote terminals and a matching station. Each user enters trading information into his or her remote terminal. The matching station then uses the trading and ranking information from each user to identify transactions between counterparties that are mutually acceptable based on the ranking information, thereby matching potential counterparties to a transaction. Once a match occurs, the potential counterparties transmit negotiating messages to negotiate some or all terms of the transaction.  Thus, the negotiated matching system first matches potential counterparties who are acceptable to each other based on trading and ranking information, and then enables the two counterparties to negotiate and finalize the terms of a transaction.
Patent CA-2198213-A1 (CA)
Title: Wax hydroisomerization process
Inventor: DOUGHERTY RICHARD CHARLES
IPC: C10G45/64
Filed: 1995-08-30
Abstract: Petroleum waxes are converted to high Viscosity Index lubricants by a synergistic process which employs two catalysts. Viscosity Index and yield are greater for product of the integrated catalyst process than they are for the product of either of the catalysts alone. The wax feed which may be pretreated by mild hydrocracking, is first subjected to isomerization in the presence of hydrogen over a low acidity zeolite isomerization catalyst which effects a preferential isomerization of the paraffin components in the feed to less waxy, high V.I. isoparaffins. The isomerization is operated at a pressure of at least 5617 kPaabs hydrogen partial pressure (reactor inlet). The catalyst is preferably a noble metal containing zeolite beta catalyst which contains boron as a framework component of the zeolite in order to give a low alpha value, typically below 20. The isomerization is carried out a a temperature of 345 ~C with conversion in the range of 10 to 40 wt.% of the feed. The product of the isomerization process is then contacted with a shape-selective catalyst in order to further reduce the pour point. Preferably ZSM-22, ZSM-23 or ZSM-35 is used. The shape-selective catalyst preferably contains noble metals such as Pd or Pt.

IPC: B41J2/175
Filed: 1997-07-04
Abstract: Reinforcing ridges are formed so as to project from corner portions of peripheral walls, and an opening end edge is made thick-walled, so that an ink cartridge having a sufficient rigidity can be molded using polypropylene that is not air-permeable but that is soft. In addition, shape keeping ribs are formed so as to project from the outer sides of longitudinal ribs that are formed on an inner surface of a cover body, so that deformation of the cartridge can be suppressed during vibration welding. Further, a support rod is engaged with a engaging recess-arranged in a lower surface of an ink cartridge, and a carriage cover body is closed while guiding a lifter with a guide groove that in parallel to the axial center of an ink supply needle. As a result, the ink cartridge is allowed to descend correctly toward a recording head, so that the ink cartridge can be loaded correctly without breaking the ink supply needle.
