International Classification:

C22C 3300

US Classification:

420129

Abstract:

The present invention relates to a novel process for producing silicon and/or aluminum containing iron alloy product as well as the material produced from same in either sheet or bulk structure form for electromagnetic circuit application. The process entails modifying an iron feedstock containing less than about 2. 5 wt % silicon, aluminum or a combination thereof. The process further consists of diffusion of silicon or silicon and aluminum or aluminum into an iron feedstock by a pack diffusion or a chemical vapor deposition method in which the iron feedstock is heated to a temperature at which diffusion occurs in the presence of a pack containing silicon and/or aluminum sources, a reducing agent, a catalyst, and a filler, or in the presence of a flowing gas stream containing a volatile silicon compound. The resulting iron alloy product, which has a silicon content in the range of 0. 25%--7% silicon, and an aluminum content in the range of about 0%--4% aluminum, has favorable properties for motor and transformer applications.

Abstract:

A portable door lock comprises a planar lock plate for extending from a door frame and a door edge with a transverse tongue at one end that passes through a frame striker plate into a recess. Apertures in a central portion of the lock plate align with apertures in a block that slides on the lock plate. A locking pin extends through registered apertures in the block and lock plate to lock the block relative to the lock plate when the block is slid against the door.

Abstract:

An occupant-restraint deployment system and method for an automotive vehicle measures an initial vehicle velocity and a vehicle acceleration over a discrete time interval and calculates a vehicle velocity. An energy-momentum (e-m) waveform is determined for the time interval based upon the vehicle velocity and a vehicle mass. A semimetric distance is calculated between the e-m waveform and each of a set of signature waveforms characterizing collision classes. Identification of a collision class is then made based upon the semimetric distances, and deployment of an occupant restraint is activated if the identified collision class indicates a collision for which deployment is appropriate.
