Patent CA-2367914-A1 (CA)
Title: Utilizing a leveraged passive commodity index portfolio to diversify a base portfolio
Inventor: SPERANDEO VICTOR A
IPC: G06Q40/00
Filed: 2000-03-10
Abstract: A unitary investment instrument that may be either a swap or a note instrument, both of which provide multiple utilization of capital. The unita ry instrument has two performance components. An investor must either deposit collateral (22) with the issuer (in the case of the swap instrument) or inve st in the issuer the principal amount of the investment (in the case of the not e instrument). The first component is a base portfolio (24), and second component is keyed to a passive commodity index, having long and short positions. The instruments' commodity index exposure (26) is established as the product of a leverage factor and the amount of the base portfolio exposure; thereafter this exposure may be the product of (1) a leverage fact or and/or (2) the change in value of the investment or either component thereof . The return to the investor comprises the change in value (32b, 34b) of both the base portfolio exposure and the passive commodity index exposure over a predetermined period of time (30). When configured as a note, the investment  instrument includes a guarantee of the return of the investment principal, b ut includes a payout factor, less than one, reducing the amount of the change i n the base portfolio and commodity index portfolio exposure reflected in the value of the note and reflecting the opportunity costs of the guaranteed payback.

Title: Method for operating extruder temperature controller with stable temperature reset
Inventor: EIVA SAULIUS TOMAS
IPC: B29C48/92
Filed: 2001-02-08
Abstract: The invention is a method for operating an extruder temperature controller.  The method can include sensing an actual screw speed for an extruder screw in an extruder barrel. The extruder barrel has at least one heat exchange means. The method can then involve indexing and storing a plurality of screw speeds. Each of the stored screw speeds corresponds to a temperature reset value. Comparing the actual screw speed with each of the stored screw speeds can then be performed. Selecting one of the stored screw speeds can then occur. The selected screw speed is a member of the plurality of stored screw speeds having a value most arithmetically equivalent to the actual screw speed. The step of selecting retrieves the temperature reset value corresponding to the selected, stored screw speed. Generating a control output driver signal to the heat exchange means can occur. The control output driver signal is responsive to the retrieved temperature reset value.  The invention includes delaying a control alarm for a predetermined time when generating a control output driver signal to the heat exchange means is at or near maximum capacity.
