Title: Rule based vector space model for creating implied trade templates
Inventor: ACUNA-ROHTER JOSE ANTONIO
IPC: G06F17/00
Filed: 2010-09-01
Abstract: A match engine is utilized by either a market participant or an electronic trading system. The match engine receives orders, stores them internally, calculates tradable combinations and displays or otherwise publishes the tradable combinations or the order(s) needed to complete tradable combinations. The match engine operates under a set of rules that may be customized to provide only the tradable combinations that are likely to be executed and contribute to total trading volume. At least some tradeable combinations that are not likely to be traded are not calculated, which frees up the computing capacity of the electronic trading system.

Title: Fluidic impulse generator
Inventor: STANDEN ROBERT
IPC: F15B21/12
Filed: 2010-09-28
Abstract: A device for vibrating tubing as it is inserted into a wellbore is disclosed.  The device has a fluidic switch that has no moving parts. The fluidic switch is connected to a piston that oscillates back and forth in a cylinder. The piston is the only moving part.  As the piston oscillates, it blocks and unblocks openings in the cylinder or other components. The movement of the piston controls the timing of the oscillation, and also generates an impulse or vibration.  The vibration may reduce the friction between the tubing and the wellbore.
