Abstract: A website structure for populating the registration database of a website, and for providing access to information contained within various community areas that comprise the website. A plurality of community areas are provided via website pages which contain information pertaining to a community interest. Each registered user will have a home page with personal information. Other overlying community areas might provide group information to which a user belongs, or organizational information to which a group belongs, and so forth. The information within the community areas can be viewed and shared by various users of the website, with access to the information controlled by the status of the user. The membership database for the website is built via invitations from member users to non-member users. An identification can be assigned to each relationship.

Abstract: A dryer for particulate material combines the drying effect of a stream of heated gas circulated by a blower in a closed duct system with that of a radiator structure which is in the drying chamber and is in a heat pump circuit. The condenser of the heat pump circuit is in the duct system where it condenses moisture from the gas which has passed through the particulate material. The heat pump compressor is driven by an internal combustion engine which is in a compartment in heat exchange relationship with the duct system. The engine cooling system radiator is immediately downstream from the condenser and the engine exhaust system includes a heat exchanger which is in the duct downstream from the engine cooling radiator.
