Abstract: A solar energy heat collector includes two water transport ducts, a plurality of branch water ducts and heat collection plates. The water transport ducts are located on two sides of the heat collector having two opposing sides with a plurality of fastening holes formed thereon to be coupled with two ends of the branch water ducts by soldering. Each of the heat collection plates has an upper side with a downward concaved holding portion formed thereon and fastening portions on two sides. One fastening portion on one side is bent upwards and another on another side is bent downwards. The holding portion is bonded to a lower side of the branch water duct, and the connection juncture of the branch water duct and the heat collection plate is fastened by soldering. The fastening portions are bonded and overlapped in series in an up and down manner and fastened by soldering.

Abstract: A method for workflow processing of objects stored in the memory of a computer system in accordance with the invention includes storing an object, which is to be processed, in the memory of a computer system; reading the object, which is to be processed, from the memory, and adding a graphical symbol to the object; processing the graphical symbol with middleware; and in response to the processing of the graphical symbol with the middleware initiating actions to process the object in accordance with business rules; and wherein the graphical symbol is an object which, when interpreted by the middleware into a computer readable format, initiates an action resulting in the use of at least one tool to process the object with each tool performing a different operation on the object or at least one additional object event or changing at least one attribute of the object, based on business rules, with the rules being comprised of at least one of the set of controls or procedures under which a computer implemented bus
