Patent CA-2080323-A1 (CA)
Inventor: MIYO TOKIHIRO
IPC: H04L27/00
Filed: 1992-10-09
Abstract: A phase angle ~ of a received signal is calculated according to a formula ~ = tan-1 (Q/I), where I and Q are magnitudes of baseband signals obtained by quadrature detection of the received signal, and an angular velocity .DELTA.~ of the phase angle ~ is calculated.  A variance parameter .SIGMA.~ is calculated from a deviation ~ = .DELTA.~ - .DELTA.~, where .DELTA.~ is a moving average of the .DELTA.~, andthe variance parameter .SIGMA.~  thus calculated is compared with a reference value to decide existence of a burst signal.  Since the decision is performed essentially not based on an amplitude of the received signal but based on a phase of the received signal, fluctuation of the amplitude of the received signal does not affect the decision.

Title: Integrated procedure for high yield production of chlorine dioxide
Inventor: WESTERLUND G OSCAR
IPC: C25B1/26
Filed: 1992-12-17
Abstract: ABSTRACT OF THE DISCLOSURE      A novel continuous process and system are provided for the production of chlorine dioxide at favourable economics and  high  efficiency.    The  process  involves  effecting electrolysis  of  an  aqueous  solution  of  alkali  metal chloride,  in an electrolysis zone,  to form an aqueous solution of alkali metal chlorate having a chlorate ion concentration of 400 to 1,200 g/L,  and a chloride ion concentration of 90 to 120 g/L, gaseous hydrogen and water vapor.    Hydrogen  is  conducted to  a hydrogen  chloride synthesis  system  where  it  reacts  with  chlorine  gas, (recycled, as well as make-up,) to yield hydrogen chloride gas which is quenched with water to provide hydrochloric acid.   A solution of alkali metal chlorate is conducted from the electrolysis zone to the chlorine dioxide generat-ing zone to provide over 400 g/L chlorate ion concentration and over 90 g/L chloride ion concentration.  The reaction is driven by the high chlorate ion concentration, high reacting  temperature  and  with  the  hydrochloric  acid injected through multi-capillary tubes at high velocity.          The reaction provides chlorine dioxide gas with some by-product chlorine, which is at least in part separated by an auxiliary chlorine dioxide absorbing in-loop system.  The unreacted  chlorate/chloride  solution  from the  chlorine dioxide generator is recycled to the electrolysis zone.          The alkali metal is sodium or lithium at the very high chlorate ion concentrations.  The method includes methods for recovering chlorine as gas or an equivalent chloride for recycle within the process system.

Title: Louver frame and method of installing a louver in the frame
IPC: E04B9/24
Filed: 1993-02-18
Abstract: A frame for a louver holds the louver below the ceiling surface, away from a light fixture. This helps to collimate the light rays and direct the light downward, thus preventing unwanted sideways glare. In addition, the use of a frame tends to hold the louver more securely in the ceiling framework. The frame is formed of Z-shaped members, with one arm of the Z resting on the T-bar cross-bar and the other arm supporting the louver. A stop along one side of the frame prevents movement of the louver in the frame. In one aspect of the invention, rotatable angle supports at the ends  of the frame rotate from a vertical position for use during louver  installation to a horizontal  supporting position  for  supporting the louver in the frame.

Title: Erbium doped optical devices
Inventor: FELDMAN LEONARD C
IPC: H01S3/06
Filed: 1993-05-13
Abstract: This invention embodies an optical device with a Fabry-Perot cavity formed by two reflective mirrors and an active layer which is doped with a rare earth element selected from lanthanide series elements with number 57 through 71. The thickness of the active layer being a whole number multiple of .lambda./2 wherein .lambda. is the operating, or emissive, wavelength of the device, said whole number being one ofthe numbers ranging from 1 to 5, the fundamental mode of the cavity being in resonance with the emission wavelength of said selected rare earth element, Cavity-quality factors exceeding Q = 300 and finesses of 73 are achieved with structures consisting of two Si/SiO2 distributed Bragg reflector (DBR) mirrors and an Er-implanted (.lambda./2) SiO2 active region. The bottom DBR mirror consists of four pairs and the upper DBR mirror consists of two-and-a half pairs of quarterwave (.lambda./4) layers of Si and SiO2. Photoluminescence at room temperature reveals a drastic enhancement of the luminescence intensity of the cavity emitted along the optical axis of the cavity versus the luminescence without the top mirror. The luminescence intensity of the cavity is typically 1-2 orders of magnitudes higher as compared to structures without a cavity. Furthermore, since the emission wavelength and the intensity decrease for off-normal emission angles, the change in emission wavelength can be quantitatively described by assuming that the on-axis component of the optical wave is resonant with the cavity.

Title: Chloride assisted hydrometallurgical copper extraction
Inventor: JONES DAVID L
IPC: C22B15/00
Filed: 1993-07-28
Abstract: A process for the extraction of copper from a sulphide copper ore or concentrate comprises subjecting the ore or concentrate to a first leaching at an elevated temperature and pressure in the presence of oxygen and a lixiviant which comprises an acidic solution of chloride and bisulphate or sulphate ions to produce an insoluble basic copper sulphate. The basic copper sulphate so produced is leached in a second leaching preferably at atmospheric pressure with an acidic sulphate solution to dissolve the basic copper salt to produce a leach liquor containing copper sulphate in solution. The resulting leach liquor is subjected to solvent extraction to produce a copper concentrate solution and a raffinate comprising protons and bisulphate or sulphate ions in solution.      Protons, and bisulphate or sulphate ions are extracted from the raffinate to produce a sulphuric acid solution which sulphuric acid solution is then recycled to the first leaching at elevated pressure and temperature to serve as a source of bisulphate or sulphate ions in the lixiviant. According to a preferred embodiment, the extraction of the protons and bisulphate or sulphate ions from the raffinate is effected by means of an electrodialysis process. In alternative embodiments copper sulphate is also extracted from the raffinate and recycled to the first leaching step or alternatively a source of bisulphate or sulphate ions, such as a hydrolyzable metal sulphate, is introduced from another source.
