Granted: 1999-05-04
Abstract: A switched reluctance motor (M) comprises a stator assembly (SA) including a stator (S) having a central bore (B) and a plurality of inwardly extending salient teeth (ST). A plurality of stator windings (W) are installed on the stator teeth. A rotor assembly (RA) includes a (R) rotor mounted on a rotor shaft (RS) and installed in the central bore for rotation with respect to the stator assembly. The rotor assembly has a pluralitry of outwardly extending salient teeth (RT) with gaps (G) extending lengthwise of the rotor assembly between adjacent rotor teeth. A noise reducer assembly (10) installed on the rotor assembly reduces the noise produced by the rotor when the motor is operating at normal speeds. The assembly includes a lug (14) made of an electrically non-conducting material inserted in each rotor gap and extending the lengthwise of the rotor assembly. Each lug is hollow with sidewalls (16A, 16B) and an inner endwall (16C) all of whose contours generally form mating contours with the respective sidewalls of the rotor poles and the contour of the rotor at the inner end of a gap. An outer endwall (16D) of a lug has a curved contour the curvature of which generally corresponds to the curvature of the outer face of the rotor poles. The lugs produce a surface between the outer faces of the adjacent rotor poles which generally conforms to the outer surface (F) of the rotor poles for the outer surface of the rotor assembly to begenerally uniform thereabout. This helps reduce motor noise. The assembly also includes a cap (20) fitting over each end of the rotor assembly. The lugs are attached to the cap so to install the lugs on the rotor assembly.

Title: Antibody to aminoterminal propeptide of type 1 procollagen, and assay method using it
Inventor: RISTELI JUHA
IPC: C07K1/13
Filed: 1996-04-19
Granted: 2010-10-19
Abstract: Aminoterminal propeptide of type I procollagen exists in serum in two forms: classical type I procollagen which is a heterotrimer containing two pro .alpha.1-chains and one pro .alpha.2-chain of type I procollagen, and an .alpha.1-homotrimer type I procollagen containing three identical pro .alpha.1-chains. These intact, trimeric aminoterminal propeptides may be isolated without the use of proteolytic enzymes and the resultant propeptides may be used to prepare antibodies specific for the intact trimeric propeptide, having no affinity for the monomeric form of the propeptide. Such antibodies are useful in methods of assaying intact trimeric aminoterminal propeptide of type I procollagen in serum, without false information resulting from inadvertent assay of the monomeric form of the propeptide.

Abstract: In order to limit overload currents in electric lines, caused by a short circuit for instance, the invention calls for a current limiter to be inserted in the electric line to limit the overload current to a given multiple of the nominal current.  The simple, compactly designed current limiter has, disposed on each side of a disc-shaped insulator (1), a composite conductor made up of a high-temperature superconductor (3, 3') and a normal conductor  (4, 4') connected flat against each other to give good electrical contact.  Between the composite conductors and the insulator (1) is a chemically insulating buffer layer (2) made of 2-µm-thick silver.  Either the superconductor  side or the normal-conductor side of the superconductor makes flat contact with the insulator (1). The electrical resistance of the shunt (4, 4) should not be greater than that of the superconductor (3, 3') connected to it.  Each composite conductor is meander-shaped in design and electrically connected so that the current in adjacent strips of the composite conductor flows in opposite directions.

Title: Method of manufacture of a plastic component which is insensitive to the elements, and a plastic component so manufactured
Inventor: JAMBOIS JOHN C
IPC: B29C48/07
Filed: 1997-05-14
Granted: 2005-01-18
Abstract: A method of forming a plastic component. The method includes a first step of forming a substrate by pulling fibrous material, having been wetted out by a resin, through a first die and partially curing the composite formed so that it maintains its ultimate shape. The surfaces to be coated are treated to create free radicals (bonding sites) which are then available for bonding the acrylic compound. Thereafter, an acrylic compound is applied to the substrate to form a coating directly thereon. Application is effected by passing the partially cured and treated substrate through a crosshead extrusion die. There the substrate curing is promoted, and the acrylic compound coating is bonded directly to the substrate. The invention also includes a fiber reinforced plastic component manufactured in accordance with the method.

Title: Date value reduction system
Inventor: COLIZZA TINA
IPC: G06F9/44
Filed: 1997-08-26
Granted: 2000-03-21
Abstract: A date value reduction system resolves the "Year 2000" problem in data processing. The input and output problems are resolved with the use of a "date translation object" (DTO) which translates an input date into a processing date (a reduced date value for processing purposes). This DTO similarly translates the processing date into an output date which is the actual date. The DTO may be embodied as a short sub-routine that can handle all possible date translation requests, whether adding the date value or subtracting it. A call to the DTO  is made at any time the processing software receives an input or outputs date related data. This call is inserted at the input and output command statements of the processing software. The command statements are readily located using a conventional hunting program. The insertion of the DTO is a simple process of locating the date references and scanning the processing instructions for input and output command statements used by the processing software language. This significantly minimizes the reprogramming of system programs and automatically ensures that the output data supplied to other systems or to users of the system needs no subsequent translation.

Abstract: In a self-healing network, virtual paths between user terminals are classified according to different fault recovery priority levels and communication links are mapped to virtual paths accommodated by the links and to bandwidths remaining in the respective links. Each priority level guarantees a fault recovery with a different amount of network resource. In response to a fault-indicating message identifying a failed virtual path, a search is made through the link-path table for an alternate virtual path and a remaining bandwidth of each link that comprises the alternate virtual path in descending order of the priority classes. In accordance with the priority class of the failed virtual path relative to the priority class of an existing virtual path that shares the same link with the alternate virtual path, a decision is made on whether or not the bandwidth guaranteed by the priority class of the failed virtual path can be allocated to the alternate virtual path from the remaining bandwidth. If the decision is affirmative, the alternate virtual path is established.
