Filed: 1992-12-21
Abstract: The invention relates to a method of determining a short-circuit inductance in an asynchronous machine. To enable the de-termination of the snort-circuit inductance even during the operation of the machine, the method comprises the steps of causing a step change in the stator voltage (u s); measuring both the stator voltage (u s) and the stator current derivative (~~) both before and after said step change in the stator voltage; determining the difference between the measured stator voltages (u s(t ~), (u s(t ~)) and the difference between the measured stator current derivatives (i s,(t~), (~ s(t ~)); and determining the quotient of the difference between the stator voltages and the difference between the stator current derivatives for obtaining a short-circuit inductance (~~~).

Title: Dual element magnetoresistive sensor with antiparallel magnetization directions for magnetic state stability
Inventor: GILL HARDAYAL S
IPC: G11B5/39
Filed: 1995-02-13
Abstract: A dual element magnetoresistive (MR) sensor is disclosed comprising two MR elements separated by a high resistivity conductive spacer material. A layer of hard bias material, which abuts one of the MR elements at each of its track edges, has a magnetization times thickness value substantially matched to that of the one MR element to bias it in one longitudinal direction. An exchange bias layer biases the other MR element by exchange coupling in an opposite longitudinal direction to achieve magnetic stabilization between the MR elements.

Title: Vaccum deposition and curing of liquid monomers
Inventor: AFFINITO JOHN D
IPC: H01M10/058
Filed: 1993-07-30
Abstract: The present invention is the formation of solid polymer layers under vacuum.  More specifically, the present invention is the use of "standard" polymer layer-making equipment that is generally used is an atmospheric environment in a vacuum, and degassing the monomer material prior to injection into the vacuum. Additional layers of polymer or metal or oxide may be vacu-um deposited onto solid polymer layers. Formation of polymer layers under a vacuum improves material and surface characteris-tics, and subsequent quality of bonding to additional layers. Further advantages include use of less to no photoinitiator for cur-ing, faster curing, fewer impurities in the polymer electrolyte, as well as improvement in material properties including no trapped gas resulting in greater density, and reduced monomer wetting angle that facilitates spreading of the monomer and provides a smoother finished surface.

Title: Stamped metal toroidal hybrid gas generator with sliding piston
Inventor: CLARK RANDALL J
IPC: B60R21/26
Filed: 1995-09-22
Abstract: A hybrid inflator comprises a housing formed of welded-together metal stampings defining a toroidal gas chamber surrounding a center tie and storing pressurized gas therein.  The center tie has a generally cylindrical sidewall and an outlet wall at an upper end thereof defines a rupturably sealed outlet orifice.  An inverted stamped metal cup is matingly received in the center tie. The lip of the cup is welded to the lower end of the center tie, and the cup sidewall is circumferentially grooved for separating a sliding piston portion under pressure.  A squib support wall and squib closes the lower end of the center tie and inverted cup to define a combustion chamber containing a pyrotechnic gas generant which, upon ignition, causes the inverted cup to separate at the groove and drive the sliding piston upwardly to an open position uncovering inlet openings from the combustion chamber to the gas storage chamber.  Hot gasses from the combustion chamber flow into the gas storage chamber and the outlet orifice rupturably opens permitting stored gas and combustion products to exit the inflator.  The sliding piston and center tie are tapered to control movement of the piston by friction and deformation, together with lanced limit stop tabs.  The cup has a convex bottom, deformation portions and may carry a lance to open the orifice.  A baffle provides a surface on which incomplete products of combustion are collected and captures debris.  A deformable outlet diffuser provides compact packaging.
