Patent CA-2326980-A1 (CA)
Title: Low cost amplifier using bulk optics
Inventor: DUCK GARY S
IPC: H01S3/16
Filed: 2000-11-28
Abstract: The present invention relates to an in-line optical amplifier that can be coupled to optical fibre, wherein the amplifying medium has a substantially larger mode field than the optical fibre to which it is coupled. The present invention has realized a design to utilize a very high power pump launching a multimoded signal having approximately 1 W of pump power into a block of erbium doped glass having a mode field diameter orders of magnitude larger than the mode field diameter of erbium doped fibre. This invention provides a relatively inexpensive optical amplifier that is compatible for use in an optical fibre telecommunications system or for other uses. Advantageously, this invention provides a device that does not require unwieldy lengths of erbium doped fibre to form an amplifier. By using a block of glass having a rare earth therein, packaging, temperature stabilizing and temperature tuning of the amplifier also become practicable. Furthermore, a cylindrical block of glass having planar ends, lends itself to applying coatings or filters thereto, thereby forming selective filters at ends of the erbium doped block to allow the pump light in, and the signal light in at opposite ends, while preventing light at the pump wavelength to propagate out with the amplified signal.

Title: Optical disc and optical disc apparatus for identifying synchronization patterns thereof
Inventor: KAWASHIMA TETSUJI
IPC: G11B7/004
Filed: 2000-12-08
Abstract: The objective of the present invention is to facilitate to identify whether or not the optical disc is a optical disc of which recording capacity is enlarged. A synchronization pattern of ATIP information embedded into guide grooves irradiated with a light spot is made to be different between a high density optical disc and a standard density optical disc of which recording capacity is not enlarged. Specifically, while the synchronization pattern of the standard density optical disc is made into "3T+1T+1T+3T" (where "T" represents a minimum channel bit of a signal obtained by reading a positional information), the synchronization pattern of the high density optical disc is made into "3T+3T+1T+1T" for example. By reading the ATIP  information and recognizing the synchronization pattern thereof, it can be easily and quickly identified whether the optical disc has a standard density or a high density.

Abstract: Cannabinoids have been found to have antioxidant properties, unrelated to NM DA receptor antagonism. This new found property makes the cannabinoids useful i n the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune disease s. The cannabinoids are found to have particular application as neuroprotectant s, for example in limiting neurological damage following ischemic insults, such  as stroke and trauma, or in the treatment of neurodegenerative diseases, suc h as Alzheimer's disease, Parkinson's disease and HIV dementia. Nonpsychoactiv e cannabinoids, such as cannabidoil, are particularly advantageous to use because they avoid toxicity that is encountered with psychoactive cannabinoi ds at high doses useful in the method of the present invention. A particular disclosed class of cannabinoids useful as neuroprotective antioxidants is formula (I) wherein the R group is independently selected from the group consisting of H, CH3, and COCH3.

Abstract: Process for the laser and/or plasma cutting of strips, particularly metal coils, and relative continuous cutting lines in which, upstream of the cutting line, there is a strip of metal in the form of a coil supported on a reel, positioned for unwinding, and in which the said strip is initially straightened and then, by means of a transport system, is sent downstream towards a support bed, and is locally processed by the movement of an overhead focusing head which is part of the laser or plasma cutting unit. While cutting, the said focusing head is mobile and moves exclusively along the axis which is transversal to the longitudinal forward travel axis of the said strip. The said strip is carried further downstream by an evacuation table, on which both the waste pieces and the finished pieces or details remain together, after which they are later separated.

Filed: 1999-12-14
Abstract: Disclosure of methods and apparatus providing bases for design of compact small bore medical needle retraction safety devices (10, 60', 60", 400, 600) wherein actuators (170, 630) are displaced away from slender needle sheathing bodies (40, 40', 40", 410) to initiate a needle retraction cycle for safely containing a medical needle (70) after use. Four embodiments of the instant invention are disclosed.      In one embodiment (10, 60, 60'), needle retracting energy is stored as a medical needle (70) is extended for use and is expended to retract the needle (70) into safe containment.      Other embodiments (400, 600) comprise power assist mechanisms (430, 440, 490, 510, 512, 514, 610, 640) which store energy during an initial phase of needle retraction to be used to enhance and assist needle retraction during a needle retraction completing phase. In some embodiments (60, 60"), retraction is facilitated by a pair of rigid, elongated, hingedly interconnected arms (90, 100, 90', 100'), which are further hingedly coupled to a needle hub assembly (30) and to a device body (40, 40') such that one arm (100, 100') is rotated approximately 180° to retract the needle (30) a distance greater than the length of the rotated arm (100, 100') to facilitate retraction actuation. One power assist mechanism comprises a part (192) molded as a distortable member of one of the arms (90).

Abstract: Crushed and de-fatted oilseed is extracted with water at neutral, mildly basic or mildly acidic pH; and is filtered. The filter media allows passage of small fragments of solid cell meat into the filtrate. The filtrate is treated with a base to increase pH to over pH 9, and solids are separated out. Protein is separated from other constituents of the liquid and concentrated, for example by heat-induced or isoelectric precipitation and/or ultrafiltration. The remaining liquid is rich in sugars. The process results in one or more protein products suited for human or animal food ingredients or for production of cosmetics, a sugar rich product suitable for fermentation or use as a feed ingredient, and a fiber-protein animal feed ingredient.
