Title: Apparatus for charging batteries of electric vehicles
Inventor: WICK THOMAS
IPC: B60L11/18
Filed: 1996-10-11
Abstract: An apparatus for charging batteries of electric vehicles, which have an electronic control device with a regeneration option. The apparatus has a d.c current source in a charging station and contacts for connecting the d.c. source in the changing station with the electric vehicle. The regeneration option of the electronic control device is used as the charge-control circuit. This permits the creation of an actual charging lane that has contact rails, with which electric vehicles come automatically into electrical contact by wiper contacts when entering the charging lane. Since each electric vehicle has an individual control circuit for driving and regeneration, and therefore its own charge-control circuit, it is possible to charge the batteries of differently equipped electric vehicles via their wiper contacts by the same d.c. current source.

Abstract: A fluid damped bushing (10, 100) comprising a metallic sleeve (12, 112) and an annular elastomeric body (14, 114) mold bonded to the exterior of the metallic sleeve. The elastomeric body has a spaced apart pair of fluid containing recesses (18, 118 and 20, 120) in its exterior surface with a serpentine shaped inertia track (26, 126) in the outermost surface of the elastomeric body to provide communication between the recesses. A window metal sleeve (16, 116) is encapsulated within the elastomeric body by mold bonding, and the window metal sleeve has a longitudinally spaced apart pair of rings (30, 130 and 32, 132) above and below the level of the recesses, respectively, and a diametrically opposed pair of webs (38, 138 and 40, 140) extending between the rings. In a first embodiment, a plurality of outwardly projecting pads (28) is located in one of the webs in the region of the inertia track to prevent deformation of the inertia track under load. The annular elastomeric body is inserted into an outer metallic sleeve (36, 136), while the sleeve and the elastomeric body are immersed in a damping fluid, and the diameter of the outer sleeve is then reduced by a swaging process to tightly seal the sleeve against the annular elastomeric body and to seal the damping fluid in the recesses and the inertia track. In another embodiment of the invention the metallic sleeve (112) has a generally elliptical, axially short rigid polymeric collar (140) affixed to the central portion thereof. The radially longer lobes (140a) of the collar are aligned with the recesses (118, 120) and serve to limit the amount of radial deflection of the bushing (100).

Filed: 1997-03-17
Abstract: An electromagnetic dam is employed to confine a vertically disposed pool of molten metal at the open end of the space between two counter-rotating, casting rolls in a continuous strip caster.  The dam comprises three magnetic flux conductors each having a pair of spaced-part surfaces adjacent to and facing in the direction of the pool of molten metal. Two such surfaces of a first flux conductor define a relatively wide air gap adjacent the top part of the molten metal pool; two such surfaces of a second flux conductor define a relatively narrow air gap adjacent the bottom part of the pool, at the nip between the casting rolls; and two pool-facing surfaces of a third magnetic flux conductor are disposed between the spaced-apart surfaces of the first flux conductor in the wide air gap.  Coils, for conducting a time-varying electric current, are associated with the three magnetic flux conductors to develop, at the air gaps, horizontal magnetic fields which confine the molten metal pool at the open end of the space between the casting rolls.

Title: Methods for aiding in the diagnosis of alzheimer's disease by measuring amyloid-beta peptide (x->=41) and tau
Inventor: SEUBERT PETER A
IPC: C12N15/09
Filed: 1995-11-13
Abstract: This invention provides methods useful in aiding in the diagnosis of Alzheimer's disease. The methods involve measuring the amount of amyloid-.beta. peptide (x- >=41) in the cerebrospinal fluid of a patient. High levels of the peptide generally are inconsistent with a diagnosis of Alzheimer's. Low levels of the peptide are consistent with the disease and, with other tests, can provide a positive diagnosis. Other methods involve measuring the amounts of both A.beta.(x -. gtoreq.41) and tau.  Low levels of A.beta.(x- >=41) and high levels of tau are a positive indicator of Alzheimer's disease, while high levels of A.beta.(x->=41) and low levels of tau are a negative indication of Alzheimer's disease.

IPC: A61F9/007
Filed: 1995-12-04
Abstract: Methods and systems are disclosed for corneal reprofiling employing an annular beam of ablative radiation to correct refractive errors in vision, and/or create "blend zones" in order to reduce any surface discontinuities on the cornea following hyperopia-correcting or astigmatism-correcting procedures. Preferably, the methods and systems of the present invention also operate to change the intensity distribution of the light beam, such that the annulus of radiation has a varying intensity as a function of radius and, thereby, achieves a blending or other desired effect with the least number of pulses. Methods of photorefractive keratectomy (PRK) are disclosed, including the steps of (a) selectively reprofiling a cornea of an eye by removing a volume of corneal tissue with ablative radiation to form a reprofiled region in the optical zone which steepens, at least in part, the central curvature of the cornea; and (b) applying to a peripheral region of the cornea an annular beam of ablative radiation having an intensity which varies radially from a inner to a outer segment of the annular beam to create a blend zone, thereby providing a smooth transition between the repro filed region and an unablated region of the cornea. Optical lens elements also are disclosed having a generally conic front face and a rear face which is generally perpendicular to the path of the incident beam.  Light passing through this optical element will be refracted into an annular beam.  Variations in the intensity profile of the annular beam can be introduced by employing an initial beam which has a non-uniform profile, or by modifying the shape of either the front face or the rear face of the optical element.
