  • Central risk pricing system and method
    Patent number: 11830072
    Abstract: A pricing administration and calculation tool comprises user interface logic, pricing administration logic and pricing calculation logic that cooperates with the user interface logic to generate display screens configured to receive user inputs specifying credit guarantee pricing and user inputs specifying terms and conditions for mortgage backed security (MBS) loan commitments. The inputs are specific to individual external user (seller). The credit guarantee price is a fee for guaranteeing to an investor the timely payment of principal and interest from the mortgages underlying a mortgage backed security. The credit guarantee pricing may be specified via the display screens on a seller-by-seller basis, a mortgage product-by-product basis, an issue month-by-issue month, and a coupon-by-coupon basis.

  • Repeater pipette with a hydraulic operating device
    Patent number: 6440370
    Abstract: A pipetting system including a syringe (2), a working piston (5) connectable with the syringe piston (24) and extending into a working chamber (3), an actuating piston (7) extending into the working chamber, and a storage chamber (4) connected with the working chamber (3) by a valve (12) that provides for flow of the hydraulic liquid, which fills both chambers, from the working chamber (3) into the storage chamber when the working piston (5) is displaced into the working chamber (3), for flow of the hydraulic fluid from the storage chamber (4) into the working chamber (3) when the actuating piston is displaced out of the working chamber, and that separates the storage and working chambers (3, 4) when the actuating piston (7) is advanced into the working chamber.
