Title: Protective system for high temperature metal alloys
Inventor: GORODETSKY ALEXANDER S
IPC: C23C26/00
Filed: 2001-05-22
Granted: 2005-04-12
Abstract: A method for protecting low-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 stainless steel with a coating of MCrAlXSi in which M is nickel, cobalt, iron or a mixture thereof and X is yttrium, hafnium, zirconium, lanthanum, scandium or combination thereof. A blended powder composition to produce a desired MCrAlSiX surface alloy may be applied to the substrate. The overlay coating and stainless steel substrate preferably are heat-treated at about 1000 to 1200°C for about 10 minutes or longer to metallurgically bond the overlay coating to the substrate and to form a multiphased microstructure. The obtained surface alloyed structure is preferably aluminized by depositing a layer of aluminum thereon and subjecting the resulting coating to oxidation at a temperature above about 1000°C for a time effective to form an alumina surface layer.

Abstract: A self-lubricating swage expands tubulars and includes a primary swaging tool supported on a mandrel that has a lubricious capacity or a primary swaging tool supported on a mandrel and a nose swage member supported on an end of the mandrel. In the latter the nose swage member is fabricated of, is coated with or otherwise includes and applies a lubricious material that smears onto a surface coming into contact with the nose swage member. The smearing of the lubricious material facilitates the sliding of the swaging member as it contacts the inner walls of the tubular.

Title: Method for detecting a loose blade in a hand piece connected to an ultrasonic surgical system
Inventor: FRIEDMAN ALLAN L
IPC: G01R23/02
Filed: 2001-10-17
Granted: 2010-02-16
Abstract: A method for detecting loose blades in a hand piece connected to an ultrasonic surgical system by performing frequency sweeps of a drive signal through a range which includes the resonance of a hand piece/blade system and the resonance of the hand piece without a blade attached. The frequencies of resonance in each sweep are compared. If a substantial difference between the frequency sweeps occurs, then a "Tighten Blade" message is displayed on a liquid crystal display on an ultrasonic generator console. The method permits rapid and easy diagnosis of loose blade connections. The method also assists a surgeon or nurse in knowing when to tighten the blade, as opposed to performing more lengthy and detailed diagnostic or cleaning procedures. In addition, the time and costs associated with the diagnostic procedures to isolate faults are eliminated because, upon determining that the blade is not loose, the surgeon and/or nurse can request a new blade based on the assumption that the blade is broken.

Abstract: The public Internet is the world's largest system of inter-net-worked computers. Adequate security means for protecting sensitive data com-municated over the Internet is not, however, provided. The present invention, therefore, provides a system and method for performing secure transactions over an insecure packet-switched communication network. This is achieved by inter-connecting a number of master nodes over the insecure communication network.  The master nodes are capable of transmitting encrypted data packets over the in-secure network via pseudo-random communication paths. The master nodes are further capable of returning to any state in a secure transaction in the event of a network failure. The master nodes are also capable of using new keys to encrypt each data packet.

Abstract: A hydraulic actuator is provided for controlling relative movement between first and second structures between which the actuator is mounted, for example between a boom and the base frame of an agricultural sprayer, while providing some resilience in the form of suspension. The actuator comprises a piston cylinder having a floating cushion piston supported within the cylinder end to support the piston within the cylinder in a retracted position at a prescribed spacing from the cylinder end. The piston can thus be deflected from the retracted position in either direction using a pressure relief mechanism so as to provide some flexibility to the actuator to accommodate the varying forces between the pair of relatively movable structures between which the actuator is mounted. The cushion piston requires no additional electrical switches or controllers and can be part of the hydraulic circuitry of the actuator so as to provide a simple, low cost actuator with integral suspension.

Abstract: A method for reactivating a solid alkylation catalyst is provided which can be performed within a reactor that contains the alkylation catalyst or outside the reactor. Effective catalyst reactivation is achieved whether the catalyst is completely deactivated or partially deactivated. A fluid reactivating agent is employed to dissolve catalyst fouling agents and also to react with such agents and carry away the reaction products. The deactivated catalyst is contacted with the fluid reactivating agent under pressure and temperature conditions such that the fluid reactivating agent is dense enough to effectively dissolve the fouling agents and any reaction products of the fouling agents and the reactivating agent. Useful pressures and temperatures for reactivation include near-critical, critical, and supercritical pressures and temperatures for the reactivating agent. The fluid reactivating agent can include, for example, a branched paraffin containing at least one tertiary carbon atom, or a compound that can be isomerized to a molecule containing at least one tertiary carbon atom.
