Patent CA-2127654-A1 (CA)
Inventor: KIRSCHNER MARK J
IPC: D21C9/10
Filed: 1994-07-08
Abstract: An oxygen delignification method and apparatus in which a charge of heated wood pulp is reacted with oxygen in the presence of a charge of caustic soda in a plurality of reaction stages located between mixing stages in which caustic is mixed with the wood pulp. The use of the plurality of mixing stages reduces peak pH exposure of the wood pulp that would otherwise occur if the charges of caustic and wood pulp were mixed all at once. Moreover, the caustic mixed in such manner replenishes neutralized caustic and ensures that the average pH level is increased above that in conventional oxygen delignification. The increase in average pH level favors an increase in the delignification. Filtrate from a washing stage is introduced into the mixing stages to prevent wood pulp degradation. Oxygen is mixed within the wood pulp by a wood pulp mixer that employs coaxial perforate passageways between which the wood pulp is retained and driven but which allow the oxygen to pass in an inward radial direction of the passageways to mix with the wood pulp.
Patent CA-2131326-A1 (CA)
Inventor: DUGGER CORTLAND O
IPC: C01F7/78
Filed: 1993-03-01
Abstract: This invention relates to a generic process for producing a refractory oxide at a temperature below the melting point of the pure refractory oxide, by the steps of heating a fully hydrated halide or a hydrated halide-oxide dried cationically homogeneous nanostructured mixture to a temperature at which a cationically homogeneous nanostructured solid state hydroxyhalide is produced. The solid state hydroxyhalide is then heated to its decomposition-temperature, at which it decomposes, by heat alone, into a cationically homogeneous nanostructured solid state oxyhalide; and performing one of the following heating steps: (i) heating the solid state oxyhalide to a solid state oxyhalide decomposition-temperature at which it chemically decomposes, by heat alone, into a cationically homogeneous nanostructured solid state refractory oxide; or (ii) heating the solid state oxyhalide to a molten state decomposition-temperature at which it chemically decomposes, by heat alone, into a cationically homogeneous nanostructured solid state refractory oxide; or (iii) heating the solid state oxyhalide to a vapor state decomposition-temperature at which it chemically decomposes, by heat alone, into a cationically homogeneous nanostructured solid state refractory oxide.

Title: Upright liquid containing container system with self seal valve
Inventor: DEFLANDER JOSEPH F
IPC: B65D47/20
Filed: 1993-08-30
Abstract: A container system is provided for a liquid which has a viscosity below 1000 mPas. The container system comprises a dis-charge orifice (13) which is sealed by a retractive self seal valve (3). In particular, the invention relates to a standing plastic bottle (1) for dishwashing liquids having a retractive self sealing valve (3) over its disharge orifice (13). When squeezing the bottle (1) to discharge liquid the retractive self sealing valve (3) pops out first (fig. b) before a slit (25) in the top portion of the self sealing valve (3) opens to squirt out liquid (fig. c). Upon releasing pressure from the bottle (1) the slit (25) closes and the valve (3) retracts (fig. a). This provides improved separation between the liquid and the bottle cap such that a less messy discharging operation is achieved.

Title: Speech-rate modification for linear-prediction based analysis-by-synthesis speech coders
Inventor: KLEIJN WILLEM B
IPC: G10L21/04
Filed: 1995-03-20
Abstract: Synergy between operations performed by a speech-rate modification system and those operations performed in a speech coding system is exploited to provide a speech-rate modification system with reduced hardware requirements. The speech rate of an input signal is modified based on a signal representing a pre-determined change in speech rate. The modified speech-rate signal is then filtered to generate a speech signal having increased short-term correlation. Modification of the input speech signal may be performed by inserting in the input speech signal a previous sequence of samples corresponding substantially to a pitch cycle. Alternatively, the input speech signal may be modified by removing from the input speech signal a sequence of samples corresponding substantially to a pitch cycle.

Filed: 1995-10-11
Abstract: A fishing accessory comprises a base and a bracket pivotally mounted on the base,  for  retaining  a fishing rod in position.   The bracket is movable to enable the rod to be displaced from an armed position to a rest position, thereby performing a striking action.   An elastic member is connected between the bracket and the base and is held in an extended  position  by  means  of  an  over-centre mechanism when the rod is in the armed position.          The  over-centre  mechanism  is  activated  when  a pulling  force  is  exerted on  a  fishing  line attached to the rod, thereby releasing the elastic member to displace the rod to perform the striking action.

Abstract: L' invention concerne une méthode et un équipement pour effectuer la restitution de pointage en élévation d'une antenne radar, en particulier pour l'imagerie radar à synthèse d'ouverture. L'erreur entre le pointage théorique et le pointage réel en élévation est calculée à partir d'une comparaison entre des signaux somme .SIGMA. et différence .DELTA. qui sont effectivement fournis par l'antenne radar en réception, et ces mêmes signaux calculés à partir des données théoriques. Le signal différence .DELTA. est obtenu en appliquant un déphasage de 180.degree. sur une moitié de l'antenne réception avant d'effectuer la somme des signaux reçus. Un microprocesseur fait la comparaison entre la courbe théorique (.DELTA./.SIGMA.)T et la courbe bruitée du signal effectivement reçu et mésuré par l'antenne (.DELTA./.SIGMA.)M, et effectue, par le calcul, un glissement de la courbe reçue en fonction de l'angle d'élévation, afin de minimiser la différence entre les deux courbes. L'angle de glissement calculé constitue l'erreur de pointage en élévation.
