Abstract: Methods for creating a customized document using a downloadable product design tolls executing in the user's browser. A template for a partially completed product design is selected by the user and downloaded to the user's computer for editing by the user at the user's computer using the downloadable design tools. While viewing the product design template, the user can enter text or other content into the template elements. The completed product design can be uploaded to the server for production of the corresponding printed product.

Abstract: Systems, methods and computer program products are disclosed for providing an edit location indicator. The indicator is displayed to a user while the user is performing editing actions to create an electronic document design that is intended to undergo subsequent printing and processing to produce a printed product. The indicator has a number of individually modifiable sections, each indicator section corresponding to a physical section of the type of product being designed. When the user performs an electronic edit action, the section of the product corresponding to the location of the edit action is identified and the corresponding section of the indicator is modified to present to the user a visual indication of the section of the product affected by the edit action.

Abstract: Fuel for a diesel engine is fed to the engine through a small float tank provided with a fuel heater. A cooling unit is employed to cool overheated fuel recycled from the engine. A temperature controlled valve is utilized to divert recycled fuel from the cooling unit through the float tank and back to the engine if the recycled fuel is sufficiently cool. The fuel heater, cooling unit and valve are adapted to optimize fuel temperature based on engine performance design.Water, propane, LPG, etc. also may be injected into the engine along with the diesel fuel to improve the combustion process and fuel economies.
