Filed: 1993-10-08
Abstract: The present invention relates to a digester for continuous cooking under raised pressure and temperature of fibre material in a vertical digester (1), where input of fibre material and cooking liquid takes place at the top of the digester, withdrawal of spent cooking liquor is carried out from at least one digester strainer girdle (1D) between the top and the bottom of the digester, and fibre material is fed out from the bottom (1C) of the digester, wherein an existing digester (1) is fitted with an additional di-gester strainer girdle (2) above the lowest strainer girdle (1B) of the digester so that the temperature in all the participatory coo-king zones in the digester can he kept at essentially the same temperature level.
Patent CA-2149812-A1 (CA)
Title: Treatment of contaminated water in clays etc.
Inventor: CHERRY JOHN ANTHONY
IPC: E21B49/00
Filed: 1995-05-19
Abstract: The treatment system involves the use of hydrofracturing in drilled boreholes over the treatment area.  The hydrofracturing fluid contains treatment material, of the kind that causes chemical breakdown of the contaminant.  The breakdown leads to a contaminant concentration of zero in the hydrofracks, and therefore the contaminant diffuses towards the hydrofracks, where it is in turn broken down. Calculations and measurements indicate whether natural cracks in the ground are far enough apart to make hydrofracturing worthwhile.  A formula indicates, from an assessment of diffusion coefficients, etc, whether the contaminant will be rendered safe within a given time period.

Title: Pressure Forming of Glass Sheets
Inventor: CLAASSEN GEORGE R
IPC: C03B23/023
Filed: 1995-09-19
Abstract: The present invention discloses a method for shaping glass sheets to deeply sagged configurations using a lower outline mold and an upper shaping mold while minimizing marking of the sheets by shaping molds. The outline mold includes a support rail which generally corresponding to the desired curvature of a peripheral portion of the sheets to be shaped and supports the glass sheets as they are heated and sagged by gravity to a preliminary shape. The outline mold and the upper mold are then moved relative to each other to position the molds either in close proximity to each other or to press the upper mold against the glass sheets. Pressurized gas is then directed from the mold to at least the unsupported central portions of the preliminarily shaped sheets, to urge these unsupported portions downward and shape the sheets to a desired configuration,

Title: Mail processing system with unique mailpiece authorization assigned in advance of mailpieces entering carrier service mail processing stream
Inventor: PINTSOV LEON A
IPC: G06Q20/40
Filed: 1995-10-03
Abstract: A mailing list is created including destination addresses for mailpieces to be submitted to a carrier service for delivery. A unique mailpiece identifier associated with mailpieces on the mailing list is generated by the carrier or other trusted third party. The unique mailpiece identifier is printed on the mailpiece with which it is associated. The mailpieces with the printed unique identifier are submitted to the carrier service. The carrier service obtains the printed unique identifier from the mailpiece. The obtained unique identifier from each said mailpiece is utilized to verify that data associated with the mailpiece has been processed by the carrier or trusted third party. When the unique number has been obtained from the mailpieces, the carrier service, if desired, may note this fact in the carrier records to prevent reuse of the unique identifier. The carrier service as part of issuing the unique identification may: charge the mailer's account of other fund depository for the carrier service charges associated with the mailpiece; and/or, assign a destination delivery code; and/or, provide address hygiene for the mailpiece; and/or change of address processing. When the unique identifier is obtained from the mailpiece, a delivery point destination code may be printed on the mailpiece, based on the corrected address. As an alternative, the destination delivery code may be provided to the mailer with the unique mailpiece identifier to be printed on themailpiece by the mailer. Various cryptographic techniques may be employed to authenticate the mailer and the carrier service and to protect the transmitted information between the parties. The payment for the carrier services can be implemented prior in time to the entry of the mailpieces to the carrier service mailstream. Unauthorized mailpieces may be out sorted early in the carrier service processing procedure.

Patent CA-2167966-A1 (CA)
Title: Tonality for perceptual audio compression based on loudness uncertainty
Inventor: ALLEN JONATHAN BRANDON
IPC: G10L19/035
Filed: 1996-01-24
Abstract: A new technique for the determination of the masking effect of an audio signal is employed to provide transparent compression of an audio signal at greatly reduced bit rates. The new technique employs the results of recent research into the psycho-physics of noise masking in the human auditory system. This research suggests that noise masking is a function of the uncertainty in loudness as perceived by the brain. Measures of loudness uncertainty are employed to form noise masking thresholds for use in the compression of audio signals. These measures are employed in an illustrative subband, analysis-by-synthesis framework. In accordance with the illustrative embodiment, provisional encodings of the audio signal are performed to determine the encoding which achieves a loudness differential, between the original and coded audio signal, which is less than (but not too far below) the loudness uncertainty.

Inventor: LIFSHEY ARTHUR L
IPC: H04L29/06
Filed: 1994-12-19
Abstract: An ophthalmic package (1) is formed by injection molding, having a thick wall with a limited flexible area (22), which limits internal displacement of the walls of the package (1) when squeezed to thereby deliver a certain amount per squeeze.

Patent CA-2177378-A1 (CA)
Inventor: BRANN JOHN E T
IPC: G06F9/40
Filed: 1994-11-21
Abstract: A computer programming method is provided for translating source messages to target messages. The translational steps are described in a database in which all necessary instructions and data are stored. A control program has the limited functions of responding to source messages and accessing the database. The database then directs the control program to access subroutines called translation method programs. The translation method programs then access the source message in a step-by-step process to translate the source message to the target message. The translation method programs sends messages to the control program to advise if each step in the translation process have or have not been successfully accomplished. The control program, responding to the database and the translation method programs, then delivers the completely translated target message to the receiver.

Patent CA-2184524-A1 (CA)
Inventor: MANDEL BARRY P
IPC: B65H31/24
Filed: 1996-08-30
Abstract: In a sheet stacking system for stacking plural sheets from a printed sheets output path into at least one sheet stacking tray, including a stack height sensor for detecting the height of the stack of sheets in the tray and controlling a stacking control system; the stack height sensor has an elongated maximum stack height sensing bar, and a sensing bar movement system for intermittently moving the maximum stack height sensing bar into the tray in an operative measurement position on top of the stack of sheets in the tray at a position transversely of the sheet entrance path, with a normal force pressing downwardly against the top of the stack. The stack height sensing bar in this position extends across the top of the stack at the height of the highest level of any portion of the stack, in particular, overlying the sets stapling area. A sensing system is actuated by the height of the stack height sensing bar in this measurement position to provide signals to the stacking control system, which provides a control signal when the maximum stack height in the sheet entrance path to said sheet stacking tray reaches a height which is preset below the height which would obstruct the sheet entrance path. This sensor system can move, to measure several bins, and can also provide a sheet knockdown function.
