Patent NO-164625-C (NO)
Inventor: LEFEVRE HERVE C
IPC: G02F1/09
Filed: 1982-11-08
Abstract: A single, continuous strand of fiber optic material 32 is wrapped about a mandrel 70 to form oval-shaped loops having parallel sides 82, 84. 88, 92 and curved ends 78, 83, 86, 90. A magnet 100 is positioned so that its B-field is substantially parallel to the straight portions 82, 84, 88, 92 of the loops. As light propogates through these straight portions 82, 84, 88, 92 of the loops, its direction of polarization is rotated in accordance with the Faraday effect. The curved portions 78, 83, 86, 90 are formed to create sufficient linear birefrigence to provide a phase difference ot 180 degrees between light in the two orthogonal polarization modes of the fiber 32. This causes the Faraday rotations in each of the straight portions 82, 84, 88, 92 to add, rather than cancel.The magneto-optic rotator of the present invention is useful in a variety of applications such as an optical isolator, a modulator, and a magnetometer.

Abstract: This invention relates to flame retardant phenol aldehyde foams which have a k value below 0.020 W/mk. The foams have as flame retardants a blend of a halosubstituted diphenyl oxide and an organic phosphorus compound. The feature of the invention is that unlike conventional flame retardants, the blend now used does not adversely affect the low k value i.e. the low thermal conductivity of the foam.

Patent CA-2014551-C (CA)

Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE        In optical branching equipment which is supplied with an optical signal of a first wavelength band from a trunk line terminal equipment via a trunk line cable and is inserted in the trunk line, the optical signal is normally provided to the trunk line cable after being bypassed from a branching circuit to branch line terminal equipment connected to a branch line cable, and when trouble develops in the branch line, the optical signal is delivered to the trunk line cable via a short circuit. In the short circuit there is inserted an optical limiter amplifier which is capable of amplifying light of the first and second wavelength bands.  Normally the optical limiter amplifier is saturated by control light of the second wavelength supplied from the branch line terminal equipment via the branch line cable, and consequently, the optical signal of the first wavelength band is suppressed.  When the supply of the control light is stopped by some cause, the optical limiter amplifier amplifies the optical signal of the wavelength band provided to the short circuit and provides the amplified optical signal to the trunk line cable.

Granted: 1995-01-17
Abstract: A slip control device for a vehicle provided with an internal combustion engine, wherein an engine output torque is controlled independently of a depression of the accelerator pedal so that slip at the driving wheels of the vehicle is controlled.  A stand-by means is provided and operates, upon a prediction of an occurrence of slip at the vehicle wheels, to close the throttle valve to a stand-by degree of opening thereof before the occurrence of the slip.  The stand-by degree of opening of the throttle valve is controlled in accordance with an engine torque of the engine when the occurrence of slip is predicted.  Thus the occurrence of slip is effectively prevented and a good acceleration performance obtained.

Title: Spectrophotometric instrument with rapid scanning distortion correction
Inventor: NORRIS KARL H
IPC: G01J3/28
Filed: 1990-09-27
Granted: 2000-08-22
Abstract: In a spectrophotometric instrument, a system is provided to correct for distortion caused by rapid scanning of the spectrum. In the instrument, photodetectors detect light energy which is scanned through a spectrum at a rapid rate. An amplifier amplifies the output signal generated by the photodetectors. The output signal of the amplifier is sampled at increments and the samples are converted to digital values. A first derivative is determined from the digital values by subtracting from each value the value from the preceding increment. The first derivative values are multiplied times a constant selected to correct for the distortion and the resulting product values are added to the amplitude digital values to provide a set of corrected values representing the intensity detected by the photo-detectors.

Title: Compression device
Inventor: DYE JOHN F
IPC: A61H1/02
Filed: 1992-06-23
Granted: 2002-06-18
Abstract: This invention relates to venous blood flow in a patient's limb which is promoted by repeating a cycle of sequentially applying compressive pressures against a patient's limb through means of a flexible, pressurizable sleeve having pressure chambers progressively arranged along the limb in relation to the patient's heart. Specifically, the pressure chambers from the distal to proximal are pressurized until they are at their appropriate pressures so as to collapse the veins in the limb.      At the end of the mast proximal compression, a foot chamber is compressed at a substantially higher pressure than the other chambers to force a bolus of blood from the foot into the limb causing the collapsed veins to open, the support of the chambers minimizing distention of the veins and enhancing the transmitting of blood up the limb.

Abstract: A fully internally manifolded fuel cell stack is provided by each separator plate and electrolyte in the fuel cell stack having a plurality of aligned perforations forming gas manifolds extending for the length of the cell stack. Each perforation through the separator plate is surrounded by a flattened manifold wet seal structure extending to contact the electrolytes on each face of the separator plate to form separator plate/electrolyte wet seals under sell operating conditions. Conduits through the extended manifold wet seal structure provides gas communication between one set of manifolds and the anode chambers on one face of the separator plates, conduits through the extended manifold wet seal structure on the opposite face of the separator plates provides gas communication between a second set of the manifolds and the cathode chambers on the other face of the separator plates, and conduits through the extended manifold structure of a reactant gas manifold provides communication to interspersed reforming chambers. Extended wet seal structures formed of thin plate metal provide limited flexibility and resiliency to assure good sealing. This structure provides fully internal manifolding of and separation of fuel and oxidant gases to each of the unit fuel sells in the fuel cell stack while providing reactant gas to reforming chambers interspersed along the cell axis to reform hydrocarbonaceous gas and supply enhanced hydrogen content to the fuel supply manifold.

Abstract: A series of hard disk drives are secured atop molded plastic support trays slidably and removably received in opposing guide channel member pairs snap-fitted into opposite side walls of a sheet metal cage structure externally used in conjunction with a file server or other computer device. Snap-fitted into rear end portions of the trays are small printed circuit boards that are insertable into hot plug sockets at the rear of the cage. Forwardly projecting guard plates on the rear end of the cage block manual access to the board/socket interface, and the surface mounted grounding leads on the board extend rearwardly beyond its signal leads to enhance grounding safety during disk drive installation and removal. At the front end of each tray is a vertical support plate upon which LED indicating lights are conveniently mounted for the associated disk drive. Each guide channel member has a metal grounding clip portion that is pressed against the adjacent cage wall and is contacted by a grounding screw on the disk drive as the drive is slid into the housing, the grounding screw also functioning to prevent inadvertent upside-down installation of the drive. To assist in installing and removing each disk drive, its associated support tray is provided at its front corners with pivotable ejection latch members removably secured thereto using a molded connection structure that eliminates the requirement for attachment screws or rivets.
