Title: Method and system for providing mandatorily convertible securities with an associated call spread against a trust
Inventor: ORTNER WILLIAM
IPC: G06Q40/04
Filed: 2004-07-13
Abstract: The present invention relates to a method and system for offering a novel mandatorily convertible securities (e.g., DECS) by using a third party entity (either a corporate entity or a newly-formed independent trust) to: 1) issue and sell novel DECS to market investors; 2) obtain from a first entity shares of common stock in a second entity, or rights to receive such shares in the future, to satisfy the mandatory conversion requirement of the DECS; 3) sell or retain the rights to any residual value obtained after satisfying the obligation to DECS investors; and 4) use the proceeds from such sale or retained value to fund a portion of the DECS coupon. As compared to a traditional DECS, the use of the third party intermediary allows the first entity to: 1) recognize an accounting gain/loss on its underlying position in the second entity up front on the day of sale of the novel DECS; 2) avoid the creation of debt on the balance sheet of the first entity; 3) avoid any mark-to-market through the income statement each fiscal quarter, which would produce income statement volatility.

Patent CA-2482119-A1 (CA)
Title: Sawing direction positioning system for a bench saw
Inventor: ZHANG ROSS
IPC: B23Q3/18
Filed: 2004-09-20
Abstract: The present invention relates to a sawing direction positioning system for a bench saw comprising a fight-emitting unit for emitting a planar light beam installed at a protection plate of said bench saw, said light-emitting unit being connected with a power supply via a lead and positioned to emit forward and downward said planar light beam so that said planar light beam coincides exactly with the central plane of a circular saw blade mounted on said bench saw. The projection line of the planar light beam on a wood to be sawed is a very fine straight line which marks the sawing direction for the circular saw blade. During sawing, the projection line of the planar light beam always projects on the wood to be sawed and is not obstructed by the sawdust. The operator may have a good visual field and push the wood to be sawed forwardly along the right straight line to ensure that the sawing direction is correct or keeps in line with the drawn straight line, thereby preventing the kerf from offsetting and reducing the rejected products.

Inventor: BUTLER JAMES R
IPC: C07C6/12
Filed: 2003-09-25
Abstract: A process for the production of ethylbenzene by the ethylation of benzene in the critical phase over a molecular sieve aromatic alkylation catalyst. An aromatic feedstock (32) having a benzene content of at least 90 wt.% is supplied into a reaction zone (38 and 38A) into contact with a zeolite beta alkylation catalyst having a silica/alumina ratio within the range of 20-500, specifically 50~-150. The alkylation catalyst is a zeolite beta specifically a lanthanum-modified zeolite beta. Ethylene (31) is supplied to the reaction zone to provide a benzene/ethylene mole ratio of 1-15. The reaction zone is operated under conditions in which benzene is in the supercritical phase to produce an alkylation product (45) containing ethylbenzene as a primary product with heavier alkylated by-products of no more than 64 wt.% of the ethylbenzene. The alkylation product is recovered from the reaction zone and supplied to a separation and recovery zone (47, 52, 58, and 62) to separate ethylbenzene (60) from a polyalkylated component including diethylbenzene. At least a portion of the polyalkylated component (69) is supplied to a transalkylation reaction zone (65 and 66) containing a molecular sieve transalkylation catalyst. The transalkylation reaction zone contains a zeolite Y catalyst and is operated under liquid phase conditions.

Title: Peptide oligomers for use as hiv vaccines
Inventor: BALL JONATHAN KELVIN
IPC: C07K16/10
Filed: 2003-12-12
Abstract: Partially occluded and/ or multimeric presentations of peptides mimic the epitopes recognised by antibodies capable of neutralising diverse clinical isolates of the human immunodeficiency virus type 1 (HIV-1). By ~partially occluded~ is meant a presentation that has a three-dimensional structure (probably a barrel/cylindrical/ helical shape) generated by inter-chain disulphide bridging or other means that has internally, at or near its base, the epitope that is recognised by the neutralising antibody; i.e. a partially occluded presentation is a three-dimensional presentation of one or more neutralising epitopes such that the epitope is located in a pocket or cleft.  Such presentations are better at eliciting antibodies that have the neutralising phenotype, and may be used as vaccines or to produce antibodies for the prevention or treatment of HIV-1 infection.

Title: System and method for improving the thermal efficiency of a heating system
Inventor: SPECHT WERNER
IPC: F23L5/02
Filed: 2005-10-28
Abstract: A system and method for providing a heating system with good thermal efficiency by adjusting combustion air flow in response to fuel-input rate changes over a wide range. An AC motor operates in a slip mode whereby as the fuel-input rate changes, the combustion air density is affected. In response, changes in the load and thus the speed of the motor occur. Consequently, the quantity of combustion air flow increases in response to a fuel-input rate increase. The motor switches to a synchronous speed in response to the fuel-input rate reaching a set value, e.g., 70 percent of maximum rate.
