Title: Determination of margins in a transaction system
Inventor: WYNNE STEPHEN
IPC: G06Q40/00
Filed: 2001-03-13
Abstract: A transaction system of a supplier includes a margin determination unit comprising margin table memory for storing a plurality of tables (such as financial exchange and money market margin tables), each table having rows for the table name, transaction type, client details or rating, transaction size, transaction currency, instrument type, time period(s), and margin type and amount. A selection module sequentially selects tables from memory and a comparison module compares quantities specified by successive rows of the selected table with corresponding quantities in a transaction request from a client/user. A  calculation unit calculates a margin based on information in the table if all comparisons are good; otherwise the next table is selected. A table editor allows easy updating of the tables (adding new tables, and deleting, amending or re-arranging existing tables).

Title: Apparatus and method for improving quality of elevated concrete floors
Inventor: QUENZI PHILIP J
IPC: G01C15/00
Filed: 2002-09-30
Abstract: A device and method for measuring an initial camber of a beam includes a support member positionable at a beam of a structure. The support member includes a laser receiver for receiving a laser reference plane at a first location when the support member is positioned at an end of the beam and at a second location when the support member is positioned at a central region of the beam. The initial camber of the beam is then derived by determining a difference between the first and second locations on the laser receiver. A  loose shoring system provides an adjustable length support section and a positive stop for limiting deflection of the beam at a desired amount generally equal to the measured initial camber of the beam. The stop is adjustable to set a gap approximately equal to the expected deflection or initial camber of the beam as desired.
