Publication number: 20120285583Abstract: Useful permanent magnet materials are formed by processing molten alloys of cerium, iron, and boron to form permanent magnet compositions with appreciable coercivity and remanence. For example, Ce16.7Fe77.8B5.6 has been produced with coercivity, Hci of 6.18 kOe and remanence, Br of 4.92 kG. In one practice, streams of the molten alloy are rapidly quenched (e.g., by melt spinning) to form magnetically-soft melt-spun material which is suitably annealed to obtain permanent magnet properties. In another practice, the streams of molten alloy are quenched at a predetermined quench rate to directly obtain permanent magnet properties in the cerium-iron-boron material.Type: ApplicationFiled: February 7, 2012Publication date: November 15, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Martin S. Meyer, Jan F. Herbst, Frederick E. Pinkerton

Patent number: 7462344Abstract: The invention provides a method of reversibly storing hydrogen at industrially practicable temperature and pressure conditions. A stable hydrogen storage hydride is mixed with a destabilizing hydride. The stable hydride is capable of releasing hydrogen at a first energy level. When the stable hydride is in the presence of the destabilizing hydride, the stable hydride releases hydrogen at a second energy level. The second energy level is significantly reduced from the first energy level.Type: GrantFiled: June 5, 2007Date of Patent: December 9, 2008Assignee: GM Global Technology Operations, Inc.Inventors: John J. Vajo, Florian O. Mertens, Sky Skeith, Michael P. Balogh, Frederick E. Pinkerton, Martin S. Meyer

Publication number: 20080274033Abstract: Methods of generating hydrogen-containing streams having a minimal concentration of gaseous reactive nitrogen-containing compounds, e.g., ammonia, are provided. Hydrogen storage material systems are also provided that generate such hydrogen-containing streams. A first composition comprising a nitride, a second composition comprising a hydride, and a third composition having a cation selected from the group consisting of: alkali metals, alkaline earth metals, and mixtures thereof are combined together. The hydrogen-containing stream thus generated has a minimal concentration of gaseous reactive nitrogen-containing compounds.Type: ApplicationFiled: May 3, 2007Publication date: November 6, 2008Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Gregory P.

Patent number: 7314579Abstract: The dispersion of metal-element containing additives with hydrogen storage particles of the family of hydrogen-rich materials, M?xM?yNzHd as specified herein, markedly lowers the temperature at which hydrogen is removed from the particles. For example, the dispersion of additives containing one or more of iron, nickel, palladium, or platinum with particles of Li50B17N33H133 provides a composition from which hydrogen is readily removed by heating. Use of these metals as their chloride salts makes particularly effective hydrogen release additives.Type: GrantFiled: September 21, 2005Date of Patent: January 1, 2008Assignee: GM Global Technology Operations, Inc.Inventors: Frederick E.

Patent number: 5434784Abstract: This invention relates to an apparatus for sensing a vehicle steering wheel position. A permanent magnet target wheel having a global axial magnetic field normal to a first surface is attached to a steering shaft which is rotated by the steering wheel. Multiple regions equally spaced along a common radius on the first surface are magnetically altered and sensed by magnetically responsive sensors positioned adjacent the first radius. A single region positioned within a finite radius along a second radius on the first surface is magnetically altered and sensed by a magnetically responsive sensor positioned adjacent the second radius. The magnetic sensors are responsive to passage of the multiple regions and single region as the target wheel is rotated. Detection of each of the multiple regions corresponds to rotation of the target wheel by an incremental number of degrees.Type: GrantFiled: August 26, 1994Date of Patent: July 18, 1995Assignees: General Motors Corporation, Hughes Aircraft CompanyInventors: John R.

Patent number: 4916115Abstract: Fine line superconductors of yttrium-barium-copper were formed on <100> strontium titanate substrates by the completely non-vacuum techniques of metallo-organic deposition in selective laser pyrolysis. Lines 125 micrometers wide were written in a film of metal neodecanoates, using an argon laser, prior to complete pyrolysis. An organic dye which absorbs selective laser light wavelengths, is added to the metallo-organic solution comprising the metal neodecanoates prior to laser exposure, so as to enhance absorption of the laser light at the regions of the metallo-organic film which are subsequently exposed to the laser light. The increased light absorbance at the exposed regions, results in at least partial pyrolysis of the exposed metal neodecanoates. Regions of the metallo-organic film not exposed to laser pyrolysis is developed away using a xylene wash.Type: GrantFiled: June 20, 1988Date of Patent: April 10, 1990Assignee: General Motors CorporationInventors: Joseph V.
