Title: Coating system for high temperature stainless steels
Inventor: MENDEZ ACEVEDO JUAN MANUEL
IPC: C23C28/00
Filed: 2001-06-08
Granted: 2008-01-08
Abstract: A method for protecting carbon steel and stainless steel, and particularly high temperature stainless steel, from coking and corrosion at elevated temperatures in corrosive environments, such as during ethylene production by pyrolysis of hydrocarbons or the reduction of oxide ores, by coating the steel with a coating of MCrA1 X or MCrA1XT in which M is nickel, cobalt, iron or a mixture thereof, X is yttriu m, hafnium, zirconium, lanthanum, scandium or combination thereof, and T is silicon, tantalum, titanium, platinum, palladium, rhenium, molybdenum, tungsten, niobium, or combination thereof. The coating and substrate preferably are heat-treated at about 1000 to 1200.degree.C for at least about 10 minutes, preferably about 20 minutes to 24 hours, effective to metallurgically bond the overlay coating to the substrate and to form a multiphased microstructure. The coating preferably is aluminized by depositing a layer o f aluminum thereon and subjecting the resulting coating to oxidation at a temperature above about 1000.degree.C for a time effective to form an alumina surface layer. An intermediary aluminum-containing interlayer may be deposited directly onto the substrate prior to deposition of the overlay coating and is heat-treated with the coating to fo rm a protective interlayer between the stainless steel substrate and coating to disperse nitride formation at the substrate/coating interface. Also, the coating may be deposited onto and metallurgically bonded to the substrate by plasma transferred arc deposition of atomized powder of MCrA1XT, obviating the need for a separate heat treatment. Alternatively, a blended powder composition to produce a desired MCrA1XT alloy may be applied to the substrate.

Abstract: A heater comprises an enhanced-surface area heat transfer vessel which is situated co-axially in a hot flue gas plenum. The plenum is formed by dual- wall heating jacket. Liquid flowing through the jacket is heated co-currently by the flue gas before the preheated liquid is conducted to the top of the vessel for countercurrent heat exchange therein before discharge from the bottom of the vessel. Hot flue gas flowing through the plenum is directed circumferentially by one or more spaced and perforated ring plates placed across the plenum annulus between the jacket and the vessel. Aluminum construction of the vessel and jacket with protective coatings contribute to a lightweight heater for either floor or even wall mounting. The heater is conveniently implemented in a hydronic heating system, a potable hot water system or a combination of both.

Abstract: A method of authorising a key or lock device comprises the following steps: a first user device (UD1) and a first system device (SD1) used in a first level of a lock system, such as at a manufacturer, are created. A first encryption key (Key1) is stored in the first user device and the first system device. When the user device is to be shipped to a second level of the lock system, such as a locksmith, an authentication process is carried out between the first user device and the first system device using the first encryption key stored therein. In case the authentication process was successful, a software operation is carried out by the first system device, by which the first encryption key stored in the first user device is replaced by a second encryption key (Key2). This second encryption key is stored in second system and user devices (SD2, UD2, UD3) used in the second level of the lock system, thereby making the first user device operable with the second system and user devices. This prevents unauthorised use of keys and locks.

Title: Light-distribution control device
Inventor: OYAMA NOBUO
IPC: G02B5/02
Filed: 2001-09-07
Granted: 2008-01-22
Abstract: Disclosed is a light distribution control device including a substantially plate-like or film-like light diffusion structure which transmits or reflects light and at least one surface of which has a number of ridges arranged parallel to each other. The section of each ridge taken in a direction perpendicular to the longitudinal direction substantially constitutes a part of a circle, the surface of each ridge being smooth enough not to cause significant irregular diffusion of light. In a diffraction grating effect attributable to the parallel arrangement of a number of ridges, the ratio of diffraction light quantity to incidence light quantity is adjusted through selection of the angle of circumference and maximum diameter of the section of each ridge. When light is caused to enter a surface of the light diffusion structure, the projection of diffusion distribution onto a plane perpendicular to both the longitudinal direction of the ridges and the surface of the structure is substantially symmetrical with respect to the normal at the point of incidence independently of the angle of incidence of the light.
