Abstract:
Methods and associated structures for rapidly processing messages in a distributed computing application. Rules are stored in structures defined by the present invention and methods associated therewith rapidly process the boolean predicates of the rules to determine what actions need to be taken in the distributed computing environment in response to receipt of a message published by a publishing application in the distributed computing environment. Rules argument tables store rule argument entries which each represent a single boolean predicate test clause which compare a column (field) of a published message with either a fixed value or with another column of a published message. All rule argument predicate clauses which are AND'ed to form a rule are related in the rules argument tables by a common rule_id column value. An operations table stores entries each of which describes groups of attributes of rules stored in the rules argument tables. Rather than evaluating all rules against a received message as is known in the prior art, the tables of the present invention are searched using indexed random search methods to rapidly locate only those rule arguments (predicate clauses) which are applicable to the received message. The present invention thereby rapidly locates and evaluates all rules which are applicable to a particular published message without need to locate or evaluate other unrelated rules.
Abstract:
According to one embodiment of the invention, a hammock support includes a helically shaped support member having a first end and a second end, the support member adapted to rest on a base and a pair of stability members coupled to the support member and adapted to prevent the support member from rotating around the axis of the support member. The support member is adapted to couple a first hammock to the support member at the first and second ends and a second hammock to the support member adjacent the first and second ends.

Abstract:
According to one embodiment of the invention, Hanging Chair Stand (100), a Hanging Chair Stand includes first and second support members (200 and 202) coupled to one another at the intermediate portion. (210) The support members each have a leg portion (206a and 206b) that is adapted to rest on a base and an arm portion (204a and 204b) adapted to suspend a hanging chair over a region defined by the leg portions (220). A pair of attachment members (212) may be coupled to ends of the arm portions to suspend the hanging chair over the region.

122,758. Lee, B., and Lee, S. H. May 6, 1918. Clutches, friction. - In segmental friction clutches, wedge segments E are arranged within the outer driving or driven drum A and are carried on eccentric levers D pivoted on arms B secured to the shaft, springs L between the levers and pins G on the segments normally producing disengagement. Sliding wedges arranged between the arms B and the ends of the levers D or, as shown, rotatable levers K with cam-ends 0 are employed to produce clutch engagement, automatic tightening, due to the wedge shape of the segments, being effected if there is tendency to slip.

14,838. Lee, B., and Lee, H. July 22. Rope grips.-The loose jaw c is guided by its snugs e, f in curved slots j in the other jaw g, and is depressed by the pull of the draw-bar acting through the lever a pivoted at h to the jaw g. The cam end of the lever a has a sliding connection d with the jaw block c. A link o, pivoted to the draw-bar, takes over the curved extension a of the lever a, and tends to reduce oscillation. The Provisional Specification also states that a spring wedge and screw is used for the same purpose.
Abstract:
A system for descaling a heat exchanger utilized in a produced water system of a steam-based thermal hydrocarbon recovery operation is provided. The system comprises a heat exchanger for acting on a produced water; a steam separator in fluid communication with a steam generator for separating steam of a steam quality suitable for injection into a hydrocarbon reservoir and blowdown of a lower steam quality, the blowdown being caustic; and a blowdown loop in fluid communication with the steam separator for collecting the caustic blowdown, the blowdown loop also in fluid communication with the heat exchanger for directing the caustic blowdown through the heat exchanger for descaling the heat exchanger.
