Date Aug. 16, 1984.This sterilizing apparatus comports an enclosure (1) in which two electrodes (4,5) of an electrochemical cell are supplied by a transformer-rectifier (16) for producing an aqueous NaOCl solution from a NaCl solution. During its production, the solution is distributed over the surfaces to be sterilized of the objects to be sterilized (9) by a circulation pump (7) and a distribution manifold (6) feeding canes (10) and sprinkling heads (11) by vertical distribution pipes (8).
Abstract:
Procédé permettant de délignifier des matériaux lignocellulosiques et de séparer efficacement leur constituant les uns des autres. Ces matériaux qui, éventuellement, peuvent être préhydrolysés, sont chauffés dans un milieu acide aqueux en présence de composés de phénol, le rapport en poids liquide/solide étant au moins de 0,5. Dans le cas de faibles rapports liquides/solides, c-à-d inférieurs à environ 4:1, on ajoute davantage de liquide aqueux à la masse de réaction après pulpage pour aider la filtration et le drainage. Après isolation de la pâte de cellulose solide purifiée, la phase liquide se sépare en deux couches: une couche aqueuse riche en pentose et une couche organique riche en phénols et en lignine, cette dernière fournissant, par distillation et pyrolyse du résidus, une quantité de phénols au moins égale à la quantité de phénols utilisée dans la phase de délignification ou élimination de la lignine.
Abstract:
On fait réagir un analyte en solution avec un agent spécifique de réaction qui enrobe le guide d'onde de manière à en modifier les propriétés optiques. L'indice de réfraction du matériau de guide d'onde est supérieur à celui du milieu de réaction de sorte qu'un signal lumineux injecté dans ce guide est véhiculé par des réflexions multiples totales, la distance de pénétration de l'onde évanescente associée au signal totalement réfléchi étant du même ordre de grandeur ou supérieure à l'épaisseur de la couche du produit analyte-réactif.
Abstract:
The invention is a method of making a controlled release device that is free of defects. According to one aspect of the present invention, a method has the steps of first combining an active chemical with a dried carrier into a bound friable mixture followed by combining the bound friable mixture with a polymer preform prior to forming a device. According to another aspect of the present invention, a method has the steps of heating and mixing a casting urethane with an active chemical into a first solution, heating and mixing a trialkanolamine with a soft segment cross-linker into a second solution, and mixing the two solutions. A further aspect of the present invention is a composition of a casting urethane.
Abstract:
Disclosed is a method of sizing and desizing yarn, or more specifically to a method of coating yarn with size and removing size from yarn with liquid carbon dioxide solvent.
Abstract:
The present invention is a method of near net forming of ceramic parts wherein green structures are made by combining a ceramic powder with a solventless resin. The combination preferably exhibits shear thinning so that entry into a mold and interstices of the mold is facilitated by vibration.
Abstract:
The invention is a thermal storage sheet element (1) and a method for producing it. The element comprises a porous carrier (2) defined by pore walls (3) throughout the structure and a heat absorbing material within the open pores (4). A protective carrier (5) may be used to encase the porous carrier (2). The method for making the thermal storage sheet element involves infiltrating a porous carrier (2) with a liquid activator which is contained in the wall surface of the carrier pores. Excess activator is removed leaving the open pores (4) to be filled with the heat absorbing material.
Abstract:
A thermal storage composition (44) activated by exposure to microwave energy is provided. The thermal storage composition preferably comprises a mixture (44) of at least two impregnated powders where a first powder is calcium silicate impregnated with a microwave-sensitive material, and a second powder is calcium silicate impregnated with a phase-change material to provide a free-flowing powder; the thermal storage mixture (44) may be used in a container, to provide a thermal construction comprising a seat cushion (3) having a thermal storage unit (20) therein, further, a process of storing thermal energy for release over an extended period of time is described.
Abstract:
A powder thermal storage composition activated by exposure to microwave energy including a combination of a powder, a phase-change material, and a microwave-sensitive material combined to provide an impregnated powder (43) that has at least more than 50 n % to substantially all of the individual powder particles impregnated with both the phase-change material and the microwave-sensitive material; the impregnated powder (43) may be produced by the process of: (I) mixing an emulsion with a powder; (II) mixing a powder first with either microwave-sensitive material or phase-change material and then mixing the resultant powder with the phase-change material or the microwave-sensitive material, respectively; or (III) vigorously mixing the powder while spraying microwave-sensitive material and phase-change material (either separately or as a mixture) into the vigorously mixing powder; the thermal storage mixture (43) may be used in a container, to provide a thermal construction comprising a seat cushion (3) having a thermal storage unit (20) therein.
