Title: Fibre grating stabilized diode laser
Inventor: VENTRUDO BRIAN F
IPC: H01S5/14
Filed: 1995-06-28
Granted: 2001-01-23
Abstract: A fibre Bragg grating (34) is used to stabilize the intensity and frequency fluctuations of a diode laser (26). The diode laser is connected with an opto-mechanical apparatus to the fibre which contains the grating.  The grating is formed in the guided-mode region of the optical fibre (32).  The wavelength of maximum grating reflectivity is selected to lie near the maximum of the diode laser gain bandwidth.  The output facet of the diode laser has a reflectivity approximately equal to or greater than that of the fibre Bragg grating.  The magnitude and bandwidth of the grating reflectivity stabilizes the diode laser output without appreciably reducing the optical output power from the end of the fibre.  The bandwidth of the optical spectrum of the diode laser is selected depending on the distance of the grating from the diode laser.

Patent CA-2208711-C (CA)
Inventor: ZELITT SHELDON S
IPC: G02B27/22
Filed: 1995-12-28
Granted: 2002-05-21
Abstract: A 3-dimensional image is obtained from a 2-dimensional display by varying the apparent distance of the image from the viewer on a pixel by pixel basis. This is done by positioning an array of pixel-level optical elements in alignment with the pixels in the image. In a preferred format, each of the optical elements is generally elongate and has a focal length which varies along its length with the result that the point along its length at which light enters the optical element determines the apparent visual distance of the associated pixel from the viewer. In the case of a cathode-ray tube application, controlling the position of entry of the light is done by controlling the electron beam to move a minute distance vertically as it scans horizontally. In a television application, the vertical distance may be determined by a depth component incorporated in the broadcast signal received by a television set. Applications and embodiments relating to computer monitors, film and still printed imagery are also described.

Title: Process for the manufacture of a strip material
Inventor: GASS MICHAEL
IPC: D21F7/08
Filed: 1997-01-17
Granted: 2000-11-21
Abstract: 19 In a process for the manufacture of a strip material (1) a plastics layer (5, 6) is formed at least on one side of a support (2) from a mixture of plastics materials and particulate soluble corpuscles wherein the soluble corpuscles are leachable by a solvent of a type against which the plastics material is stable. Thereafter the soluble corpuscles are leached out from the plastics layer (5, 6) with the formation of throughflow passages. According to the invention, a plastics powder is prepared as the plastics material, which is mixed with the soluble corpuscles and applied onto the support (2). By heat and pressure treatment a plastics layer (5, 6) including therein the soluble particles, is produced from the mixture of plastics powder and soluble corpuscles, prior to the soluble corpuscles being leached at least in part out of the plastics layer (5,6).

Granted: 2001-01-16
Abstract: A call defeat device to prevent calling unauthorized numbers, such as long distance, 1-900 etc., which is adapted to prevent a caller from successfully dialing one or more predetermined digit strings on a touch tone telephone connected to a given telephone line by apparatus including a touch tone decoder coupled to the telephone line and a microprocessor/memory for storing and issuing predetermined unauthorized digit strings, if dialed on the telephone, designates that the call is to be defeated. A comparator compares each digit string dialed on the telephone to the predetermined digit strings, and, if a match is sensed, a dialer sends onto the telephone line at least one DTMF digit, such as a "#", which will defeat the call in progress. In a variant of the unauthorized call defeat apparatus, if an unauthorized digit string is dialed, a mode of operation can be selected in which an audio tone, falling outside the standard passbands of all tones representing dialed digits, is applied to the telephone line so as to "jam" and thus prevent any meaningful communication on the line. The invention can be implemented as a stand alone device or incorporated into a telephone.

Abstract: An improved livestock feeder for use with an automatic feed delivery system having a feed drop tube operatively connected thereto for dispensing feed into a feed bin is disclosed. The improved feeder is provided with an adjustable feed dispensing mechanism including control levers which are operatively connected to the feed metering gates to control the flow of feed to livestock. The dispensing mechanism features a plurality of adjustable control levers which engage an array of indexing holes formed in the feeder to set the vertical height adjustment of the feed gates. The dispensing mechanism includes a graduated scale corresponding to each of the index holes to provide a standard setting for the feeder which can be utilized by an animal producer to supply of feed flow at a given stage in the. animal's life cycle to obtain a desired growth rate. In a production facility where several of the feeders are in use a standard setting for the release of feed may be obtained to reduce variations in animal growth rate. The feeder is also provided with a removable dust cover which is installed within the feed bin to reduce airborne particles generated by the automatic feed delivery system.

Title: Propylene oxide process using alkaline earth metal compound-supported silver catalysts
Inventor: PITCHAI RANGASAMY
IPC: B01J23/02
Filed: 1997-03-14
Granted: 2005-10-25
Abstract: Propylene is oxidized to propylene oxide in the vapor phase using an oxygen-containing gas and a supported silver catalyst comprising silver and a support comprised in whole or in substantial part of an alkaline earth metal-containing compound selected from alkaline earth metal titanates, tribasic calcium phosphate, calcium molybdate and calcium fluoride. Such supports provide significantly higher selectivity to the desired epoxide than would be expected from the performance of related materials. Propylene oxide selectivity may be further enhanced through the introduction of nitrogen oxide species such as NO, aliphatic halides such as ethyl chloride, and carbon dioxide into the oxygen-containing gas.

Abstract: An apparatus and a method for detecting and locating leaks in a nuclear plant, in particular a pipeline in a nuclear plant, include a collection line which is permeable to a substance to be detected and which communicates with a pump and with a sensor for the substance. The sensor has a detector for detecting the radioactivity of the substance or a branch line which communicates with a detector for detecting radioactivity branches off upstream of the sensor. If a radioactive substance reaches the collection line and penetrates it, then the location of the leak can be determined from the period of time between a pressure surge in the collection line and a response of the detector, given a known flow speed in the collection line.

Title: Reactor distribution apparatus and quench zone mixing apparatus
Inventor: KUSKIE ROBERT W
IPC: B01D3/20
Filed: 1998-12-09
Granted: 2006-08-22
Abstract: A quench zone mixing apparatus that occupies a low vertical height and has an improved mixing efficiency and fluid distribution across the catalyst surface includes a swirl chamber, a rough distribution network, and a distribution apparatus. In the swirl chamber, reactant fluid from a catalyst bed above is thoroughly mixed with a quench fluid by a swirling action. The mixed fluids exit the swirl chamber through an aperture to the rough distribution system where the fluids are radially distributed outward across the vessel to the distribution apparatus. The distribution apparatus includes a plate with a number of bubble caps and associated drip trays that multiply the liquid drip stream from the bubble caps to further symmetrically distribute the fluids across the catalyst surface.  Alternatively, deflector baffles may be associated with the bubble caps to provide a wider and more uniform liquid distribution below the plate. The distribution apparatus can be used in the reaction vessel without the swirl chamber and rough distribution system, e.g., at the top of a vessel.
