Abstract: The present invention is directed to a reforming apparatus provided with a raw material reforming unit including a heat source for generating heat when a fuel gas is burnt and adapted to reaction heat directly from the heat source, steam-reform a material, and produce a reformed gas containing hydrogen as a main component, a shift reaction unit for reducing by a water shift reaction the amount of CO contained in the reformed gas produced in the raw material reforming unit, a CO oxidation unit adapted to further reduce the amount of CO contained in the reformed gas after the process in the shift reaction unit, by oxidizing the same. These units are united as independent units. The raw material reforming unit, shift reaction unit and CO oxidation unit are arranged so that the shift reaction unit and the CO oxidation unit are indirectly heated by the heat transmitted from the heat source of the raw material reforming unit. The indirect heating is conducted by a method of heat transmission in solid by which heat is transmitted from the outer faces of the combustion chamber via an intermediate member; a method utilizing radiant heat, and a method utilizing heat of a combustion exhaust gas discharged from the combustion chamber. Since this reforming apparatus is provided with these three independent reaction sections united together, it can be miniaturized, and the heat from the heat source can be utilized effectively, and temperature control in the reaction sections can be easily done.

Abstract: A hanger device for attachment to a vertical member such as a deck railing baluster is provided. The hanger device is of simple structure and may be formed from a single continuous piece of material. The hanger device consists of an engaging portion for engaging the baluster and a hanger portion. In one embodiment, the engaging portion may be shaped to have four sections, one for each side of a four-sided baluster. In this four section embodiment, the spacing between the beginning of the first section and the end of the fourth section is made to be greater than the width of the vertical deck railing baluster, and the fourth section is angled, so that the hanger device may be rotated and then slid horizontally onto or off of the baluster. Once on the baluster, the hanger device is rotated to the position where the four sections of the engaging portion engage the baluster in a manner that grips the baluster so as to inhibit the vertical sliding of the hanger device. The hanger device may also be formed to have two tong-like end sections that are squeezed to be separated, and are then released to allow the end sections to close around the baluster.  The engaging portion and hanger portion of the hanger device may be formed in different shapes so as to accommodate different shapes (e.g., rectangular or circular) of balusters or items to be hung.

Inventor: RAHRIG JOHN G
IPC: G06Q20/00
Filed: 1998-06-12
Abstract: A virtual postage metering system (10) and method provides value added services corresponding to postage metering transactions. Funds are not stored at the user's site reducing the risk of unauthorized modification of account balances. There is a database record (60) of every mail piece, which means that verification will be improved since all valid mail pieces are known. Furthermore, the present invention enables the postal service to know the volume of mail to be processed prior to receipt of the physical mail pieces. Since more mailer data is available (e.g. when users usually mail, how much mail per day, average postage amount) the virtual postage metering system (10) enables the postal service to predict mail handling patterns. Finally, users have the option to pay as they go (130) which contrasts present systems in which funds must be on deposit prior to being downloaded to a meter although such downloaded funds may remain in the meter for weeks before being used.
