US Patent:

7829170, Nov 9, 2010

Filed:

Feb 16, 2005

Appl. No.:

11/059849

Inventors:

Christopher Bowen - Lincoln University PA, US
Kevin Edward Dove - Wilmington DE, US
Carl Jones - Baltimore MD, US
Raymond B. Minor - Elkton MD, US

Assignee:

Gore Enterprise Holdings, Inc. - Newark DE

International Classification:

B32B 3/22

US Classification:

428 664, 4283155, 524545, 526242, 526250

Abstract:

Improved expanded PTFE materials and improved gasket materials made therefrom, the gaskets being capable of forming a seal with greater bolt load retention than is possible with existing PTFE gaskets. The expanded PTFE membranes of the invention can be tailored to exhibit a matrix tensile strength in at least one direction of at least 25,000 psi, a matrix tensile strength ratio in two orthogonal directions of between 0. 25 and 4, an orientation index of 50 or less, and a density of 2. 0 g/cc or less. The improved gaskets exhibit improved mechanical properties such as high bolt load retention, low creep, high tensile strength, low stress to seal and high crystallinity index.

International Classification:

G06F017/60

US Classification:

705037000

Abstract:

In a method and system for securitizing contracts valued on an index, a special purpose entity (SPE) is provided and holds as substantially all of its assets a derivative contract with a contract dealer. The contract has an initial notional value and is tied to an index related to items traded by a multilateral transactional execution facility, such as futures contracts traded on an exchange. The held contract is also scalable so that the notional value can be increased on demand in exchange for a corresponding payment to the contract dealer and decreased on demand in exchange for a corresponding payment from the contract dealer. The SPE issues exchange tradable securities that derive value based on the value of the contract held by the SPE. To issue additional shares, assets are contributed to the contract dealer who increases the notional value of the contract held by the SPE. The increase in value of the contract supports the issuance of additional shares. Shares are redeemed by terminating some or all of the contract whereby the contract dealer reduces the notional value and provides a termination payment based on the amount of the termination and the value of the index. In one embodiment, investors purchase shares by providing to the contract dealer both a cash payment and a futures contract, the combination having a value corresponding to the value of the shares to be issued, and where the futures contract can then be used by the contract dealer to hedge the forward contract between the contract dealer and the SPE.
