Patent WO-9830856-A1 (WO)
Title: Reacteur
Inventor: CONOCHIE DAVID STEWART
IPC: C10L9/00
Filed: 1998-01-07
Abstract: L'invention concerne un réacteur (20) et un procédé de valorisation de matières solides, dont le charbon, avec une conductivité thermique basse. Le réacteur comprend une enveloppe extérieure (10) définissant un volume interne visant à conserver un lit fixe de matières solides à traiter et une pluralité de plaques (12a à 12 h) d'une matière thermiquement conductive placées au sein du volume interne. Chaque plaque est dotée d'un ou plusieurs couloirs (14a à 14h) à travers lesquels un fluide caloporteur peut s'écouler. Lors de l'utilisation, chaque plaque définit une ou plusieurs conduites thermiquement conductives entre le fluide caloporteur et les matières solides dans la région de la plaque de telle sorte que, lors de l'utilisation, pratiquement tous les solides sont chauffés ou refroidis à une plage de températures souhaitées par échange de chaleur entre le fluide caloporteur et les solides via les plaques.

Title: Bateaux et coques de bateau
Inventor: YOUNG JOHN PATRICK
IPC: B63B39/00
Filed: 1998-02-19
Abstract: L'invention concerne un bateau susceptible d'avoir une, deux ou plusieurs coques pourvues de redents (26) donnant sur l'arrière, sur le côté, de manière qu'un vide soit créé à l'arrière et que la force de traînée soit réduite sur les côtés lors de navigation à grande vitesse. De préférence, un bateau peut comprendre deux coques latérales (16, 17) et une coque intermédiaire (18) placée à l'arrière, sans redent. Toutes les coques sont reliées par un pont transversal (non représenté). Sur l'avant, les coques latérales (16, 17) définissent un passage (43) de flux avant, au-dessus de la ligne de flottaison et au-dessous du pont transversal, et vers l'arrière des passages (44) similaires de flux sont définis entre les coques latérales respectives et la coque intermédiaire. La somme des surfaces transversales des passages de flux vers l'arrière est égale à, ou supérieure à la surface transversale du passage de flux avant, que le bateau soit immobile ou en planing. Les redents (26) permettent d'obtenir un agrandissement vers l'arrière et la mise en place de façon similaire de redents sur la surface inférieure du pont transversal permet d'augmenter cet agrandissement.
Patent BG-51496-A1 (BG)
Title: Method for threaded surfaces machining
Inventor: JANCHEV IVAN G
IPC: B23C3/32
Filed: 1990-08-06
Abstract: The method is used for treatment of consecutively positioned continuous, variable pitch threaded surfaces for compression screw pairs in sealed filling machines. It includes few operations and ensures the precision of shaping and sizing processes of the threaded surfaces. According to the method, a threaded rectangular groove is treated between the turns and at different pitches. The channel's width is equal to the one between the turns of the smallest pitch. Then the rectangular thread groove is widened up to the respective size. It corresponds to the threaded surfaces with the respective pitches. The left side of the rectangular thread groove is profiled with the corresponding milling cutters, starting with the one of the largest pitch. It is mandatory that - during this treatment - the leads of the respective profiled tools at each adjacent section overlay at certain distance of the threaded surfaces with different pitches. Then the right side of the rectangular thread groove is profiled using the same profile tools, which overhauls the need of leads' overlay.

Title: Decta
Inventor: KOWALCHUK DENNIS M
IPC: G08C21/00
Filed: 1989-10-10
Abstract: ABSTRACT A device for aligning electronically or electrically the clutch gears of a hoist and or a drive system, it is known to be mounted on the clutch and sense the teeth of the gears using photo-electric cells and or the use of ultra-sound.  The photo-optic cells or ultra-sonic transducers are aligned to sense the beginning and the end of the teeth on the drum wheel.  In this invention an electronic tone or signal is transmitted from the control box which is also mounted on the clutch arm.  The transmission is received by a separate receiver usually located in an area in which it can be heard by the hoistman or the operator.  On the receiver unit it also has a tone indicator which is a light that will also tell the hoistman when the gears are aligned or not aligned. A separate power source i.e. a battery, may also be mounted on the clutch arm or power may be derived from an external source.
Patent CA-2005610-A1 (CA)
Inventor: RODRIGUEZ-CAVAZOS ENRIQUE
IPC: H04N9/28
Filed: 1989-12-14
Abstract: A dual power source output amplifier comprises at least one pair of first and second input voltage sources of like polarity, operating at low and high voltage magnitude levels respectively relative to one another, and selectively operably coupled to an output stage for driving a load, for example a convergence yoke coil, in low and high voltage modes respectively.  The first voltage input source is coupled to the output stage in the low voltage mode.  A circuit for directly sensing the output voltage couples a biasing voltage level to the output voltage for generating a high voltage demand control signal which varies directly with the output voltage.  A voltage regulator couples regulated high voltage from the second voltage input source to the output stage in the high voltage mode, responsive to the high voltage demand control signal.  The output stage operates substantially linearly in both voltage modes.  The first voltage input source is isolated from the second voltage input source during operation in the high voltage mode. High power demand is directly sensed and anticipated to preclude operational power output lags.

Title: Method for removing toxic metals from agricultural drain water
Inventor: OLSEN ORRIE C
IPC: C02F1/70
Filed: 1990-01-16
Abstract: Abstract of the Disclosure A method and system for removing toxic substances such as selenium and molybdenum from agricultural irrigation water achieves nearly 100% removal of the toxic substance economically, by a chemical reduction process.  The process is particularly efficacious for removing naturally occurring selenium and molybdenum from irrigation water which has seeped through the ground and taken compounds of these metals into solution.  Preferably, the drain tile water solution is first concentrated, to about 30% dissolved solids.  This may be economically accomplished by on site evaporation in an open pond which is impermeable to seepage. Next the concentrated brine solution is heated, preferably to about 150° F., and a reducing agent such as finely powdered iron is added to bring, for example, the selenium down from a +6 valence to +4 and lower valences.  Wettable sulfur is added to the slurry to greatly improve the effectiveness of the iron in reducing the solution.  The slurry is constantly agitated.  After a reaction time which may be about 15 minutes, an oxidizing agent is added, with the temperature of the slurry then raised to at least about 180°, with continued agitation.  This causes the selenium and/or molybdenum to form a separable precipitate, and the precipitate is separated from the remainder of the slurry.          In a preferred embodiment the iron is recycled by processing it through a separator.

Abstract: The invention relates to controlled release pharmaceutical compositions.  These contain as active ingredient valproic acid, a salt of valproic acid, an ester of valproic acid, Valpromide, or any other pharmaceutically acceptable deriv-ative of valproic acid which upon administration to humans provides a serum level of valproic acid, in combination with an additive which is selected from physiologically accept-able polymeric substances and from native proteins.          The active ingredient is usually in the range of from 10 to 80 weight per cent.  The novel pharmaceutical compositions are prepared by applying a high pressure to a mixture of the ingredients.  They result in a prolonged serum level of the active ingredient.
