Title: Verified payment system
Inventor: SLATER CANDIDA CORALIE ANNE
IPC: G06Q20/00
Filed: 1999-06-18
Granted: 2007-11-06
Abstract: A distributed verified trusted third-party system (VPS) (10) and method enable electronic/digital transactions through real-time verification and authentication, with improved privacy and security, encompassing the whole payment range from very large to very small. The VPS (10) includes hubs (16-20) storing client data and connecting clients (22) to vendors (24) to mediate secure electronic transactions. Date may be pre-registered by banks (30) and other owners, controllers, and issuers of payment systems (32). Owners of payment systems, such as corporate/purchase cards, may authorize usage by third parties within specified limits, thus enabling them to monitor and control delegated authority. A central account authority (12) provides registration services indicating which hub services which client. The VPS (10) implements a dual key transaction system, in which verified instructions must come separately and completely independently from both client (22) and vendor (24) before transaction completion via methods accepted by both parties.  The VPS (10) allows the client (22), the vendor (24), and associated payment methods and systems (30-32) to be known, with fixed quantities and pre-registered within an authorization manager. The client (22) and vendor (24) may choose the payment method and currency used at each end of any transaction, and payment is always made within a closed system without either party having access to or knowing the details of the other's payment system. Real-time audit trails for all parties concerned are implemented, in which client (22), vendors (24), and banks (30) may trace transactions, generate reports, and initiate refunds for such secure transactions. The VPS (10) is also software and/or hardware independent, implemented by any known networking configuration for any known electronic or digital transaction, using mobile phones (28), palm-tops and digital television for purchases and credit/debit payment arrangements for any form of commerce using electronic transactions.

Granted: 2005-01-04
Abstract: A plurality of ultrasound whistles (24) formed into a ceramic core (22) of a conventional spark plug (10) used in a cylinder of a gasoline combustion engine for greatly improved air fuel mixture prior to ignition. The spark plug (10) with ultrasound whistles (24) provides for increased engine performance and acceleration, improved fuel mileage, and an improved air fuel mixture thereby reducing fuel emissions into the environment. The ultrasound whistles (24) are constructed in the form of whistle holes (26). The whistle holes (26) are disposed around a circumference of the ceramic core (22) in a spaced relationship from the spark plug's electrode (20).

Granted: 2005-06-14
Abstract: An inner vertically upright perforated conduit (12) is concentric within an outer vertically upright conduit (10). The chamber (26) between the conduits is separated by fluid impervious rings forming sub-chambers (26', 26", 26"'). Hot curd cooking water is injected into the various sub-chambers in controlled amounts through corresponding valves to provide cheese at 135°F at the bottom exit port of the cheese passageway formed by the inner conduit. The water and curd/cheese together form a pressure head of at least about 2 psi at the bottom of the conduits. Raw curd is fed in a continuous process to the top of the inner conduit producing finished cheese at the bottom without moving parts. A shredder at the bottom automatically shreds the cheese. The shredder includes a rotating blade with blow out apertures for ejecting shredded cheese from a fixed shredding plate.      The shredded cheese is automatically cooled and salted in a single continuous process.
