Title: Procede de crepage de bandes de papier mousseline contenant un adoucissant, grace a l'emploi d'une poche de crepage fermee
Inventor: MCCULLOUGH STEPHEN JOHN
IPC: D21H27/40
Filed: 1996-07-16
Granted: 2008-01-22
Abstract: La présente invention concerne des produits en papier mousseline doux et bouffants qui sont le résultat de la présence d'un agent défaisant les liaisons et adoucissant dans les couches extérieures du papier mousseline, et du crêpage dans les conditions d'une poche "fermée". Les agents défaisant les liaisons et adoucissants appartiennent à un groupe de substances chimiques qui comprend plusieurs composés quaternaires d'imidazoline. Ces substances chimiques n'ont pas d'effet néfaste sur l'adhésion à la surface de séchage de la machine à papier mousseline, contrairement à la plupart des agents défaisant les liaisons. Elles peuvent donc être placées dans les couches extérieures du papier mousseline qui sont en contact avec la surface du séchoir et améliorer le crêpage. Le papier mousseline peut ensuite être détaché par crêpage de la surface de séchage au moyen d'une poche fermée, c'est-à-dire une poche ayant un angle inférieur à 80 DEG . Le crêpage par poche fermée produit normalement un papier mousseline plus épais, moins dense, mais avec un crêpage grossier. On s'attendrait à ce que le crêpage par poche fermée et la présence de la plupart des agents défaisant les liaisons dans les couches latérales du séchoir produisent aussi des structures grossières de papier crêpé. Toutefois, l'interaction entre les propriétés adhésives de l'agent défaisant les liaisons et les conditions de crêpage en poche fermée donne un tissu mousseline bouffant ayant une structure crêpée suffisamment fine qui a pour résultat une douceur d'ensemble élevée.

Title: Air impingement oven
Inventor: CARIDIS ANDREW A
IPC: A23L27/27
Filed: 1997-12-10
Granted: 2010-05-11
Abstract: An oven for continuous cooking of products carried upon a open mesh wire conveyor provides the impingement of a cooking vapor from air discharge structure having ports arrayed above and below the conveyor. The discharge ports extend laterally of the conveyor and communicate with upper and lower plenums each charged by blower fans which draw cooking vapor from low pressure corridors alongside the product conveyor. Gas, electric or thermo fluid heaters are disposed in the corridors. The discharge ports are in slot form disposed about the apex of a Vee shaped riser spaced from the adjacent riser to provide a low pressure flow channel communicating with the corridors giving a rapid velocity change of the cooking vapor from turbulent to a less turbulent flow. The distance for vapor travel between the upper discharge ports and the product carrying conveyor is variable.  Temperature and moisture content of the process vapor can be changed to suit cooking conditions.

Abstract: A method for estimating porosity of an earth formation from measurements of acoustic energy traversing the earth formation and from measurements of seismoelectric voltages generated in the formation in response to the acoustic energy. The method includes the steps of measuring the acoustic energy traversing the earth formation and measuring said seismoelectric voltages generated in response to the acoustic energy traversing the formation. A seismoelectric signal is synthesized from the measurements of the acoustic energy using an initial value of the porosity. A difference is determined between the synthesized seismoelectric voltages and the measured seismoelectric voltages. The initial value of porosity is adjusted, and the steps of synthesizing the seismoelectric voltages from the acoustic signal, determining the difference, and adjusting the value of porosity are repeated until the difference drops below a predetermined threshold or the difference reaches a minimum value. The adjusted value of porosity which results in the difference being at the minimum is taken as the formation porosity. A particular embodiment includes estimating conductivity of fluid in the pore spaces of the formation by calculating the synthetic seismoelectric voltages using an initial value of conductivity; determining a difference between the synthetic seismoelectric voltages and the measured seismoelectric voltages; and adjusting the initial value of conductivity, and repeating the steps of calculating the synthetic seismoelectric voltages, determining the difference and adjusting the value of conductivity until the difference reaches a minimum.

Abstract: This improved screening apparatus for sorting various size aggregates utilizes a screen made of polyurethane having two sets of perpendicular evenly spaced parallel webs each of which enclose a wire provided for reinforcement. If desired, the reinforcing wires can be single or multiple through either one or through both sets of webs. Web segments extend between web intersections. Areas enclosed by opposed adjacent web segments provide for the screen openings. This area can contain either a single hole or a plurality of holes to provide a number of different screen sizes. The holes increase in cross-section from the screen aggregate input side to the output side to eliminate or greatly minimize particles wedging within the holes. Backing bucker bars of various widths attached to the lower side of the screen provide a predetermined screen cross-section when their lower edges are supported horizontally. Hooks attached to opposite sides of the screen by bolts, arranged to engage mating mounting brackets, permit applying varying tension to the screen by tightening nuts which secure the bolts.

Abstract: Improvement of an existing DAB transmission system, so that a higher net data rate can be achieved while maintaining the same system quality, or the same system quality can be achieved with a much lower signal-to-noise ratio on the receiver side at the same net data rate. A symbol mapper is connected directly downstream from a convolution encoder instead of to the block generator, as in the case of the DAB system. A multi-stage channel encoder, to which the data substreams of a source date stream are distributed, is used. The source data stream is processed on the complex symbol level and not on the bit level, as in the case of known DAB systems.

Abstract: Cet appareil respiratoire autonome (10, 130) comporte une enceinte sous pression (12) renfermant un volume d'alimentation d'air respirable. Cette enceinte est en communication fluidique par le biais d'un premier étage de détendeur (22) avec un second étage de détendeur (40). Lequel second étage de détendeur est en connexion opérationnelle avec un masque facial (42) porté par l'utilisateur. Lorsque la pression disponible dans l'enceinte est convenable, le premier étage du détendeur alimente le second étage (40) à une première pression. Si la pression dans l'enceinte chute à une valeur indicative d'une baisse imminente de l'alimentation d'air, le piston de transfert (94) d'une soupape d'élévation de pression (24) se déplace. Une modification de l'état de cette soupape amène un piston d'élévation de la pression (127) à augmenter la pression de sortie du premier étage du détendeur (22). Cette augmentation de pression fait se déplacer un piston palpeur (60) et active les dispositifs indicateurs (68, 78) d'un circuit d'alarme (64). Dans d'autres réalisations, on utilise un module électronique d'alarme (132) pour signaler l'imminence d'une baisse de pression de l'alimentation d'air.
