Abstract: A securities processor includes a prematching process for validating an attributable security interest message placed by a market participant on a securities trading system This attributable security interest message relates to an individual security chosen from a plurality of securities traded on the securities trading system. A matching queue receives the validated attributable security interest message from the prematching process, and queues it for subsequent matching. A matching process obtains the validated attributable security interest message from the matching queue and compares it with previously-validated attributable security interest messages to determine if a match occurs between the validated attributable security interest message and one of the previously-validated attributable security interest messages.

Abstract: A lift ring device arranged to normally remain in a flush condition, and involving a generally U-shaped lift loop pivotally mounted upon a base plate, such as a base plate mounted on the hatch lid of a boat. The lift loop is equipped with a pair of arm portions of substantially equal length, with each arm portion terminating in a pintle bent out of the plane of the lift loop. The base plate has a central recess defined over a substantial portion of its circumference by angled sidewalls, and in such recess the lift loop normally resides. A pair of symmetrically placed pintle-receiving holes are located in the sidewalls, which holes are elongate in a direction essentially perpendicular to the plane of the central recess. The interaction of the pintles of the lift loop with their respective holes is such as to prohibit the lift loop from residing in a perpendicular direction with respect to the base plate, thus assuring that the lift ring device will not represent a trip hazard.
