Patent CA-2152016-A1 (CA)
Inventor: KOSKINIEMI JUHA
IPC: D21C11/00
Filed: 1995-06-16
Abstract: Cooking liquors of significantly different sulphidity (e.g. one having a sulphidity about 30-40% and the other a sulphidity of above 40%, e.g. about 60-70%) may be produced in a simple energy-efficient manner. Black liquor is treated to recover chemicals, and the chemicals are dissolved to produce green liquor, which is clarified, as is conventional. The temperature of a firstportion of the green liquor is decreased to effect crystallization of sodium carbonate in the green liquor by expanding the green liquor in at least two (andtypically more than three) stages with vapor being produced during expansion. The sodium carbonate crystals produced are separated from the first portion of green liquor to produce a green liquor with high sulphidity (greater than about 40%) and this high sulphidity liquor may be heated by bringing it into direct heat exchange relationship with at least part of the expansion vapor (in a number of different stages). The separated sodium carbonate crystals are dissolved to produce a low sulphide content alkaline solution, which may be heated by bringing it into indirect heat exchange relationship with a second part of the expansion vapor. Heat recovered from the last expansion stage may be used to assist in dissolving the sodium carbonate crystals, as by using a heat pump system. The second portion of the clarified green liquor is used to produce a second green liquor having a sulphidity at least 10% lower than the high sulphidity green liquor.

Patent CA-2154305-A1 (CA)
Inventor: MENOUD EDOUARD
IPC: G07F7/00
Filed: 1995-07-20
Abstract: A coin checker and card reader for use with a vending machine includes a housing having a coin slot and a separate card slot which merge into a chute that communicates with a first coin channel and a card channel. A coin inserted into the coin slot rolls through the chute into the first coin channel and passes sensors which determine whether the coin is accepted or rejected. A door is actuated to direct an accepted coin into a coin container through a second coin channel. A rejected coin is directed to a return tray through a third coin channel. A subscriber card with a memory inserted into the card slot is guided into the card channel to actuate a switch to activate a microprocessor for exchanging information with the subscriber card memory and processing a transaction. The microprocessor checks the data being exchanged to prevent loss of data should the card be removed before the transaction is completed and to vend an article only after valid data has been exchanged.

Title: Methods and apparatus relating to the formulation and trading of risk management contracts
Inventor: SHEPHERD IAN KENNETH
IPC: G06Q10/00
Filed: 1993-05-28
Abstract: Methods and apparatus which deal with the management of risk relating to specified, yet unknown, future events are disclosed. "Sponsor" stakeholders (12) specify a particular product relating to an event or phenomenon for which there is a range of possible future outcomes. "Ordering" stakeholders (13) then offer contracts relating to the predetermined phenomenon and corresponding range of outcomes. The offered contracts specify an entitlement (or pay-off) at the future time of maturity for each outcome, and a consideration (or premium) payable, in exchange, to a "counter-party" stakeholder (14). Independently of the offered contracts, the "counter-party" stakeholders (14) input data as to their view of the likelihood of occurrence of each outcome in the predetermined range into the future, or specifically at the predetermined date of maturity. Each offered contract is priced by the processing units (20) by calculating counter-party premiums from the registered data, and a match attempted by a comparison of the offered premium with the calculated premiums. Matched contracts can be further traded until maturity, and at-maturity processing handles the exchange of entitlement as between the matched parties to the contract.

Patent CA-2173319-A1 (CA)
Title: Radiation sensitization using texaphyrins
Inventor: SESSLER JONATHAN L
IPC: A61K41/00
Filed: 1994-10-12
Abstract: Texaphyrins are provided for use as radiation sensitizers. Advantageous properties of texaphyrins for use as a radiation sensitizer include: i) a low redox potential which allows radiation-induced hydrated electrons to flow to texaphyrin rather than neutralizing hydroxyl radicals, allowing hydroxyl radicals to cause cellular damage, ii) a relatively stable texaphyrin radical that reacts readily to covalently modify neighboring molecules causing further cellular damage, iii) intrinsic biolocalization, and iv) indifference to the presence or absence of O2. These properties allow texaphyrins to be particularly effective for treating the hypoxic areas of solid neoplasms.  Methods of treatment for an individual having a neoplasm or atheroma include the use of a texaphyrin as a radiation sensitizer and as an agent for photodynamic tumor therapy, or the use of a texaphyrin for internal and for external ionizing radiation. Novel texaphyrins are provided.

Patent CA-2202025-A1 (CA)
Inventor: ADOUL JEAN-PIERRE
IPC: H04W4/18
Filed: 1997-04-07
Abstract: A method and device eradicate the occasional instability inherent in analysis-by-synthesis speech/audio codecs and caused in particular by channel errors during transmission of highly periodic signals such as high-frequency sine waves. Analysis-by-synthesis techniques involve production, in response to the speech/audio signal and at regular time intervals called frames, of (a) a set of spectral parameters for use in driving a synthesis filter in view of synthesizing the speech/audio signal, and (b) a pitch gain for constructing a past-excitation-signal component for supply to the synthesis filter. In accordance with the instability eradication method, a first step consists of detecting a set of conditions including (i) a resonance condition assessed from the spectral parameters, (ii) a duration condition detected when the resonance condition has prevailed for at least the M most recent frames, M being an integer greater than 1, and (iii) a gain condition which evidences consistently-high values of the pitch gain in the N most recent frames, N being an integer greater than 1. To eradicate the occasional instability, the pitch gain is reduced to a value lower than a given threshold whenever these three conditions are detected.
