Patent CA-2219296-A1 (CA)
Title: Timer manager
Inventor: FIACCO PETER
IPC: G06F11/00
Filed: 1996-04-26
Abstract: A method and apparatus for establishing a large number of EDTOV timers (TIMER  0-TIMER 2047), each determining when an event has failed to occur on an exchange of a communications protocol. Values for each timer are maintained as a timer array. The entire timer array is read at regular scan intervals by a state machine (102) and decremented by four associated hardware decrementers (113a-113d), four timers at one time. Active time values are read, checked for zero, decremented, and written back to the timer array. If a timer is detected as having timed out, then a value is logged into a time-out FIFO and "FF"h is written back into the timer. The invention uses dedicated hardware (101) to decrement or otherwise alter the values of each timer, and a dedicated state machine (102) to read values for each timer, provide the value to the hardware (101), and then load the new value of each timer back into memory.

Patent CA-2241360-A1 (CA)
Inventor: JANI WILLIAM
IPC: E21B23/01
Filed: 1998-07-24
Abstract: The present invention is a surge anchor mechanism which comprises a main body, lower unit slidable in relation to the main body, and slip members. The slip members have at least one inclined end surface.  The lower unit has an inclined surface forming a frustoconical shape wherein the slope of the surface complements the inclined end surface of the slip member. The lower unit is aligned along the axis of the main body and movable in relation to the main body along this axis. The slip members are biased towards the lower unit and movable transversely in relation to the axis of the lower unit. As a surge occurs in the well, the lower unit and the main body are forced towards each other.  This causes the inclined surface of the lower unit to cooperate with and move along the corresponding inclined surface of the slip member forcing the slip member outward from the lower unit and into engagement with the well casing.  As the surge passes, the lower unit returns to its lowered starting position allowing the slip member to disengage the well casing and return to a resting position.

Title: Coin diameter measurement
Inventor: FURNEAUX DAVID MICHAEL
IPC: G07D5/02
Filed: 1997-01-24
Abstract: A coin diameter measuring circuit uses a pair of coils coupled in the feedback path of an oscillator so that the oscillator frequency is dependent upon the inductances of the coils and the mutual inductance therebetween. The coils are switched between aiding and opposing configuration during the time that a coin passes therebetween, the oscillator frequency in each configuration is measured, and the difference therebetween determined to provide an indication of the mutual inductance of the coils, and thence the diameter of the coin.  Preferably, the diameter is determined by the difference between the measured mutual inductance with the coin present and with the coin absent.

Abstract: L'invention porte sur un procédé de production de solution aqueuse de dioxyde de chlore consistant à faire réagir dans une cuve à réaction une solution de réaction acide contenant un acide hydroxy-carboxylique et un acide d'accompagnement avec un sel de métal alcalin d'un ion chlorite. Au titre de ce procédé, l'acide hydroxy-carboxylique, qui sert à transférer provisoirement du chlore d'un sel de métal alcalin d'un ion chlorite, ne forme pas de sel avec le sel de métal alcalin d'un ion chlorite. La solution aqueuse de dioxyde de chlore produite est, dans une large mesure, exempte d'acide chloreux et, de préférence, également exempte d'autre sous-produits comme le chlorure de sodium et le chlore libre. Ce procédé consiste, en outre, à maintenir la cuve de réaction à un pH inférieur à 5 et/ou à retirer une partie au moins du dioxyde de chlore de la solution aqueuse de dioxyde de chlore. Ce procédé permet une production rapide, rentable et sécurisée, de dioxyde de chlore sous un petit volume. L'invention concerne également un procédé de désinfection de l'eau ainsi qu'un appareil de production de dioxyde de chlore et de désinfection de l'eau.

Abstract: Disclosed are hair care compositions and methods for preparing such compositions which provide the benefits of cleaning, conditioning, curl retention, styling and setting properties simultaneously to hair in the application of a single product. The hair care compositions contain fatty alkyl amine salts, long chain quaternary ammonium salts and mixtures thereof of anionic styling polymers in a non-anionic surfactant system, wherein the surfactant system contains nonionic surfactants, semi-polar nonionic surfactants, amphoteric surfactants and mixtures thereof. The styling, setting and conditioning agents are present in the form of fatty alkyl amine salts or fatty quaternary ammonium salts which form anionic styling polymer particulate networks upon dilution in water. These networks are dispersed in the aqueous non-anionic surfactant system and are stabilized and thickened by optional swellable polymer thickening agents. Hair care compositions of the present invention can be made in the form of structured liquids, pearlescent/opaque isotropic liquids and/or translucent/clear isotropic liquids. The hair care compositions of the present invention, which allow for re-styling of the hair by wetting the hair with water, contain non-anionic surfactants, silicones, solvents or cationic polymeric conditioning agents. Furthermore, multiple application of these hair care compositions does not produce a noticeable build-up on the hair.

Filed: 1998-12-23
Abstract: An improvement in a conventional Kraft pulping process in which dust is collected from exhaust gases produced in the black liquor recovery cycle and is dissolved in water to produce a solution containing sodium chloride and sodium sulfate. The solution is filtered to yield a solid product and a filtrate solution. The filtrate solution is fed to an ion exchange unit which removes chloride and produces a purified sodium sulfate product.      The sodium chloride is removed from the ion exchange resin by water elusion, and useful recovered chemicals are recycled to the recovery cycle of the Kraft process. In one embodiment, only a portion of the dust is dissolved so that the solid product produced by filtering is primarily sodium sulfate, and that sodium sulfate is recycled to the recovery cycle of the Kraft process.
