Patent CA-2021706-C (CA)
Inventor: GRASSO GIORGIO
IPC: H04B17/40
Filed: 1990-07-20
Granted: 1995-11-21
Abstract: An optical fiber telecommunication line composed of a number of series connected optical cables arranged end-to-end includes an active core optical fiber amplifier for the transmitted signals between each adjacent pair of optical cables.  Two pumping optical radiation sources are connected to each active core optical fiber within each of the amplifiers, one source for each end of a single active core optical fiber.  One of these two sources is placed into service and the second one is kept in reserve to be placed into service if the first one fails.  A microprocessing circuit causes the sources to send distinctive recognizable alarm signals indicative of the state of an associated amplifier to terminal stations at the ends of the line and to receive therefrom control signals to control and exchange the functions between the two sources as necessary.

Title: Ultrasonic micro spectrometer
Inventor: TSUKAHARA YUSUKE
IPC: G01N29/22
Filed: 1991-10-08
Granted: 1998-01-06
Abstract: An ultrasonic sensor for use in an ultrasonic micro spectrometer includes a concave surface transducer having a concave ultrasonic wave transmitting/receiving surface and a plane transducer having a plane transmitting/receiving surface.  The concave surface transducer is capable of transmitting converging ultrasonic waves toward a specimen, wherein the waves are reflected from the surface of the specimen and are received by the plane transducer which outputs electric signals corresponding to the intensity of the reflected ultrasonic waves. Based on a signal output from the ultrasonic sensor, a spectroanalyzer forms a distribution of spectral intensity indicating the intensity of the reflected wave as a function of frequency.  A tracking generator further forms a distribution of spectral phase indicating the spectral phase of the reflected waves as a function of frequency.  Either the distribution of spectral intensity or of spectral phase can effectively be analyzed for evaluating elastic characteristics and structure of a specimen.

Granted: 2000-02-22
Abstract: A novel process for regenerating an alkylation catalyst which contains sulfone components, hydrogen fluoride and acid soluble oil.     During the alkylation process an undesirable polymeric reaction by product called acid soluble oil is formed. The buildup of this acid soluble oil in the catalyst can have a detrimental impact on its performance. The novel process utilizes adsorbent materials in a novel way so as to remove acid soluble oil from the catalyst mixture thereby providing regenerated catalyst for reuse in the alkylation process.
