Patent WO-0116030-A1 (WO)
Title: Systeme permettant de faire fonctionner plusieurs ensembles de filtration a membranes
Inventor: COTE PIERRE LUCIEN
IPC: B01D65/10
Filed: 2000-08-03
Abstract: Pour éviter de limiter le nombre des cassettes dans une installation utilisée couramment pour produire du perméat, on groupe plusieurs cassettes sous forme d'ensembles dont un, au moins, peut être isolé alors que la production de perméat par les autres ensembles n'est pas interrompue. Des fonctions auxiliaires telles que le lavage à contre-courant, le nettoyage chimique et la vérification par tests pour rechercher des défauts dans les membranes ('essai d'intégrité') dans un ou plusieurs ensembles peuvent être effectuées alors que la production de perméat continue. Le nombre d'ensembles présents dans un banc est déterminé par la période du cycle de filtration global, qui est généralement de 15 minutes, dans laquelle la période auxiliaire représente une partie mineure, qui est typiquement de l'ordre de 30 secondes. Les ensembles permettent d'utiliser des vannes tout ou rien automatiques qui s'ouvrent et se ferment plus rapidement que des vannes plus importantes. Les économies ainsi réalisées en termes de temps, d'énergie et de coût d'équipement, sont étonnamment importantes lorsqu'on effectue le rinçage à contre-courant avec du perméat, elles sont cependant encore supérieures lorsqu'on utilise une solution de nettoyage chimique. En outre, l'économie en termes de coûts d'équipement et l'économie liée au fait qu'on évite l'usure et la détérioration des pompes qui sont arrêtées et mises en route de manière intermittente, produit des bénéfices économiques inattendus. Pour réaliser des économies encore plus importantes en termes de coûts de fonctionnement, on peut utiliser un banc de cassettes ou un banc d'ensembles avec un système à 'écoulement par gravité'.

Patent CA-2005293-A1 (CA)
Inventor: WOOD JAMES A
IPC: B61C15/08
Filed: 1989-12-12
Abstract: An  energy  storage wheel spin propulsion control system for  detecting  and correcting a spinning wheel situation so that  the  maximum  available  adhesion  is  utilized to the fullest  extent  in  accelerating a railway vehicle while at the   same   time   maximizing  the  use  of  the  available processing  time to permit an appropriate amount of time for diagnostic  purposes. The  primary  data used to form the logic  inputs  is  derived  from the axle rate signals which are   fed   to  spin  energy  storage  value  threshold  and difference  comparison  sensors.    The  spin energy storage value  and  difference  comparison  sensors  supply  logical inputs  in  spin energy threshold, dissipation threshold and optimization  threshold sensors and spin rate difference sum sensor,  respectively,  which,  in turn, supply logic inputs to  spin  enable  timer  and  spin enable sensors and a spin control   logic   output   sensor.     A  slip-spin  output determination   sensor   receives   logic   signals  from  a power-brake  signal circuit and command signal from the spin control  logic  outer sensor and a slip interface circuit to cause  the  production  of  a  full requested, reduce and/or hold tractive effort command.

Abstract: ABSTRACT             CIRCULATION AND GAS EXCHANGE IN LIQUIDS            A gas  injection  or  aeration  device,  adapted  to  be  immersed in a  liquid and supplied with gas under  pressure  so that the gas emerges through  diffusion nozzles of the device as a  large quantity  of  small bubbles  to form a  liquid-gas  mixture.   The device  includes  a  substantially  vertically  disposed  riser  tube which can be an open-ended conduit or can be defined,  in use of the device,  by a curtain of the rising bubbles.   A sleeve, in which  the  nozzles  are  formed  as  apertures,  expands  under pressure of the gas  supplied to admit  the gas into the  liquid and  then  contracts  to  partially  or  wholly  close  the  nozzles when  the  gas  supply  is  subsequently  turned  off.   The  nozzle aperture may comprise an elongate  slit of generally corrugative form.   An undertube  may extend,  in use of the  device,  below the nozzles to entrain liquid to rise towards the nozzles.

Title: Very fine-sized aqueous polymeric microemulsions
Inventor: SHAH PRAVIN K
IPC: D06M101/16
Filed: 1990-03-29
Abstract: ABSTRACT           Aqueous polymeric microemulsions such as acryl-ic ester copolymers contain very fine particles having a number average particle size of generally 600 Angstroms or less. The glass transition temperature of the parti-cles is low and with respect to acrylic polymers is generally 20°C or lower.  The aqueous polymeric micro-emulsion can can be based on polymers such as an acrylic polymer or copolymers thereof, vinylidene chloride poly-mers or copolymers, acrylonitrile-butadiene (nitrile) polymers or copolymers thereof, polyvinyl chloride poly-mers or copolymers, vinyl acetate polymers or copolymers, ethylene copolymers, and the like, as well as blends of the above.  The polymeric microemulsions are made by uti-lizing at least one water soluble initiator or a redox initiator system and a low but effective amount of one or more emulsifying agents and adding the monomers thereto on an incremental basis.  Acrylic polymeric microemul-sions are desired due to their high heat stability.  The fine-size polymeric microemulsions have good film forma-tion, high pigment loading ability, unexpectedly high shear holding time, and the like.  They are thus suitable for imparting improved strength to paper and when used with various fillers improve the opacity of the paper.

Title: Anti-jackknife apparatus for trailer trucks
Inventor: HOSMER JIMMY D
IPC: B62D53/10
Filed: 1990-05-29
Abstract: ABSTRACT Apparatus for preventing jackknifing between a tractor of a trailer truck and a trailer coupled thereto is disclosed.  The apparatus includes a latch block that is movable to a deployed position forward of the front edge of the tractor's fifth wheel and a pair of stop blocks, one disposed on each side of the trailer wear plate so that a laterally extending arm of the latch block will come into contact with one of them upon relative pivotal movement of the fifth wheel and trailer wear plate beyond a predetermined angle.   Upon making contact,  the blocks prevent further angular movement.  Arms of the latch block have projecting end portions on their upper side that slide under end portions of the stop blocks which are spaced apart from the wear plate.  This secures the latch block from being sprung downward past the stop block upon occurrence of jackknifing.  The latch block is supported by a forward extension of the fifth wheel and by gussets that extend underneath the fifth wheel and are welded thereto.  All of the blocks have a substantial thickness, providing high strength locking action,  and the blocks and supporting structure may be secured to the fifth wheel and wear plate by welding and without cutting of holes or slots in those members.  The disclosed structure also includes sensors and switching devices for automatically deploying and retracting the latch block at predetermined speeds, as well as an electronic control and monitoring module that records the history of deployment and retraction events.

Title: Full swing golf trainer
Inventor: NOVOSEL JOHN M
IPC: A63B69/36
Filed: 1991-01-04
Abstract: A golf club shaft is provided with a training head that, when the club is swung, strikes a movable, upright target composed of a yieldable, light-weight material. The target presents a relatively broad, laterally facing target surface and, when struck, becomes attached to the head and is carried thereby through the remainder of the swing. The addition of the target to the head provides increased resistance to train the player to increase club head speed at impact and beyond. The training head provides visual feedback at the finish so that the player will know whether a proper swing was executed.

Title: Method of making paste detergent and product produced
Inventor: BRUEGGE ANTHONY J
IPC: C11D7/60
Filed: 1991-01-23
Abstract: Abstract METHOD OF MAKING PASTE DETERGENT AND PRODUCT PRODUCED         A method of forming a paste detergent composition includes forming two separate aqueous solutions.  The first aqueous solution includes an effective concentration, generally 1 to 70% of potassium tripolyphosphate. The second solution is an aqueous solution of a water soluble sodium based detergent builder preferably sodium hydroxide.  These are combined and due to the effective concentrations of the potassium tripolyphosphate and the water soluble detergent builder, the viscosity of the formed detergent substantially increases relative to either of the viscosities of the first or second aqueous solutions.  This provides a unique method of forming paste detergent compositions particularly for use in warewashing machines.
