Abstract: Modern steam generators typically include a radiant section and a convection section. Due to differing performance requirements of the radiant and convection sections, the radiant section often has a round cross-section, while the convection section often has a rectangular cross-section. Previous designs utilized a target wall to affect the transition. An angled transition section is disclosed herein that substantially eliminates the target wall and/or the reverse target and provides a corresponding improvement in steam generator efficiency.

Abstract: Caching is a widely used technology on the Web, particularly by search engines which follow hyperlinks and generate indexes and directories of Web pages and their contents. Indeed, some search engines allow users to view pages as they were last retrieved by the search engine. Whether a given page exits in the cache or not, however, is completely arbitrary, and so is the time of its retrieval. The ‘Web page cache-on-demand’ process allows Web users to decide exactly when a given Web page should be retrieved and cached, thereby significantly improving Web users' ability to document Web contents.

Abstract: A manually propelled automotive painting cart including a main unit, at least one auxiliary units, and a connection device. The main unit possesses a top tray unit and at least one lower tray unit attached to a portable support frame, the top tray being partitioned for tool and material storage. A shelf unit is located below the top tray providing horizontal and vertical storage space for flat materials such as paint chip books and sandpaper. Other storage elements, including a wastepaper basket and water tank, are attached to the main unit. The auxiliary unit possesses at least one tray unit attached to a portable support frame. Dispensers for rolled paper and tape, along with other storage elements, are attached to the auxiliary unit. A removable connection device detachably attaches the main unit and the auxiliary unit providing storage and transportation for all of the tools and materials required for automotive painting.
