Patent CA-2095646-C (CA)
Title: Method for co-processing organic wastes and spent nitric acid wash water
Inventor: PETERSCHECK HERMANN W
IPC: C02F11/08
Filed: 1993-05-06
Granted: 1998-11-10
Abstract: A process is disclosed for co-processing spent nitric acid wash water with organic or biological wastes under wet oxidation conditions  whereby  the  nitrogen  content  of  the  waste  and  the chemical oxygen demand and the nitrogen content of the nitric acid wash water and of the organic or biological wastes are significantly reduced.  The nitric acid wash water is the waste stream generated by  descaling wet  oxidation  reactors  used  for  the  treatment  of organic  or  biological  wastes,  especially  municipal  wastes.  The process of this invention can be carried out in conventional above ground equipment or in a subterranean, down-hole reactor having a vertical  configuration  which  utilizes  gravitational  forces  to provide a high pressure reaction environment.  The nitric acid wash water  and  organic  wastes  are  reacted  with  an  oxidant  at  a temperature greater than 150~C and a pressure suffient to keep water in the liquid state.  The nitric acid wash water is mixed with the organic  waste  or  is  introduced  through  the  oxidant  (preferably gaseous oxygen) inlet in such a manner that gas with water vapor and the remaining acid provides a liquid film so there are essentially no "dry spots" in the oxidant inlet lines.

Granted: 2004-06-22
Abstract: A method for aiding in the diagnosis of, and monitoring the progression or course of, colon cancer in a patient by measuring the amount of NCA 50/90 in a blood sample, e.g., serum sample, obtained from the patient. Measurement in a single sample of an amount of NCA 50/90 significantly higher than the mean amount of NCA 50/90 in the normal population is an indication of colon cancer in a symptomatic patient. The course of colon cancer can also be monitored by performing a series of specific immunoassays over time to determine changes in the level of NCA 50/90 in blood samples.      Increases in blood NCA 50/90 levels over time are indicative of a deteriorating condition whereas decreasing levels of blood NCA 50/90 over time indicate an improving condition.

Title: Compact single component development system with modified toner agitator and toner dispense auger disposed therein
Inventor: TROTT ROBERT E
IPC: G03G15/08
Filed: 1994-03-28
Granted: 1999-03-16
Abstract: An electrophotographic apparatus in which toner particles are moved from the toner hopper or dispenser cartridge to the developer housing and onto the donor roller in a single component development system for use in color reprographic systems. A rotating holey tube toner agitator is modified to incorporate structure or grooves on the outer peripheral surface. Further, by placing a shrouded toner dispense auger inside the holey tube, the development system architecture stays compact and improved toner powder pushing through the pre-load of toner on the donor roller results, thereby insuring delivery of fresh toner evenly across the length of the developer housing. With more efficient pre- load, agitator rotational speed and bias can be reduced, leading to less toner effluents emanating from the developer housing without adversely affecting the cycle to cycle donor roller toner reload.

Abstract: A system and method for controlling transmission signal power in a cellular mobile telephone system in which system users communicate information signals between one another via at least one cell site using code division multiple access spread spectrum communication signals. A transceiver using the power control system is also disclosed. The power control system controls transmission signal power for each cellular mobile telephone in the cellular mobile telephone system wherein each cellular mobile telephone has an antenna, transmitter and receiver and each cell-site also has an antenna, transmitter and receiver. Cell-site transmitted signal power is measured as received at the mobile unit. Transmitter power is adjusted at the mobile unit in an opposite manner with respect to increases and decreases in received signal power. A power control feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit transmitted power is measured as received at the cell-site. A command signal is generated at the cell-site and transmitted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell-site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level.

Abstract: Aqueous bleach solutions can be made by directing a spray of water onto a bulk or shaped solid (brick, tablet, block, etc.) comprising a continuous solid phase of an encapsulated source of an active halogen bleach or a solid comprising a source of an oxidizing active halogen bleach, and an encapsulated oxidizing halogen bleach source. Such shaped solids can be used to dispense uniform quantities of an aqueous bleach concentrate to bleaching locus such as a washing machine. The tablets can be made from the encapsulated bleach or from a powder mixture of a particulate, granulated or powdered unencapsulated source of active oxidizing bleach and an encapsulated source of active oxidizing bleach by forming the powder mixture into a desired shape. Such a shaped solid bleach can be packaged in a container and can then be contacted with an aqueous spray in a dispenser to create a solution of active bleach for cleaning bleaching processes. The presence of the encapsulate in the solid with the powder reduces the tendency of the solid to absorb water which can be wicked through the solid to pass water through the solid into adjacent solids.  Substantial proportions of absorbed water can cause the tablets to crack, crumble and to periodically dispense uneven, substantially large and undesirable concentrations of active bleach into a wash or bleach cycle. Such large amounts of halogen can cause corrosion of metal machine or dispenser parts, clothing damage, can cause pinholing or other fabric damage, can result in color loss or change, or can result in other undesirable effects in either the dispenser, washing machine or the cleaned item.

Title: Beamformer using coefficient restrained adaptive filters for detecting interference signals
Inventor: HOSHUYAMA OSAMU
IPC: H04R3/00
Filed: 1995-09-01
Granted: 1999-07-13
Abstract: In an adaptive array beamformer, a spatial beamforming filter is connected to a sensor array for respectively filtering and summing array signals to produce a first filter output containing a target signal that arrives in a specified direction. First adaptive filters provide transversal-filtering the first filter output to produce a second filter output not containing the target signal, using a first error signal by restraining their tap weight coefficients. The array signals are further coupled to subtractors. Each subtractor detects a difference between the second filter output of the corresponding first adaptive filter and the corresponding sensor signal to derive the first error signal. Second adaptive filters provide transversal-filtering the first error signals of the subtractors to produce third filter outputs, using a second error signal, by restraining their tap weight coefficients. The third filter outputs are summed and subtracted from the first filter output to produce an output of the beamformer, which is supplied as the second error signal to the second adaptive filters.

Abstract: An arrangement for measuring desired parameters of a contact lens by optical sectioning which comprises a support fixture on which a contact lens is positioned. The support fixture includes a container in which a pedestal is positioned, and the container is filled with a saline solution. The contact lens is placed on the pedestal completely immersed in the saline solution. A line of light is generated and directed by imaging and shaping optical elements over the edge of the container and through a selected diameter of the contact lens. An imaging camera detects and image of the light scattered at the surfaces of the contact lens at the selected diameter, which is captured by a frame grabber and is digitally stored for subsequent image processing and determination of the desired parameters of the contact lens. The analysis provides at least four basic parameters of the contact lens including the diameter (D), front radius of curvature (FC), back radius of curvature (BC), and center thickness (CT), and can also provide the lenticular curve radius, the peripheral curve radius, the sagittal height, aspherical forms and deviations of the several measured curvatures, and the power of the lens.
