Title: Non-dairy containing milk substitute products
Inventor: TRIANTAFYLLOU ANGELIKI OSTE
IPC: A23L7/10
Filed: 2002-02-13
Abstract: Efficient, selective, and economical methods for producing non-dairy, ready-to-use milk substitute cereal dispersions having intact .beta.-glucans, proteins, and natural sugars, while retaining the aroma and flavor of natural cereal.  The methods include treating a cereal substrate suspension with an enzyme preparation that comprises at least one hydrolase having the ability to hydrolyse .alpha.-glycosidic bonds and having no glucanase and proteinase effect. The hydrolase may be selected from the group consisting of .beta.-amylase, .alpha.-amylase, amyloglucosidase and pullulanase, with the proviso that when the enzyme preparation comprises .alpha.-amylase or .beta.-amylase, there is always a mixture of at least one other of the .alpha.-glycosidic hydrolases. When .beta.-amylase and .alpha.-amylase are selected, they are used as a mixture, i.e., introduced simultaneously, to provide for accelerated enzymatic hydrolysis and for reduced amounts of the enzymes than otherwise needed if the enzymes were used separately. In addition to the above-identified hydrolases, the enzyme preparations of the present invention may further comprise an isomerase, such as glucose isomerase.

Les terminaux concernés par l'hypothèse choisie sont programmés pour la transmission de données. On peut utiliser un programme de traitement de récepteurs par éliminations successive pour traiter les signaux transmis par les terminaux programmés. Dans ce cas, on peut constituer un ou plusieurs classements des terminaux de chaque ensemble, chaque classement correspondant à une sous-hypothèse à évaluer. On retient une sous-hypothèse après évaluation des caractéristiques ce chacune de ces sous-hypothèses.

Abstract: La présente invention concerne un procédé de réglage du temps de remplissage pour un spectromètre de masse comprenant un ion linéaire. On fait d'abord fonctionner le spectromètre de masse en mode d'émission et on fournit des ions au spectromètre de masse. On effectue la détection des ions lors de leur passage à travers au moins une partie du spectromètre de masse pour une durée prédéterminée, en vue de déterminer le courant ionique. On détermine un temps de remplissage de piégeage d'ions à partir d'une densité de charge maximale pour le piège à ions et le courant ionique. On fait fonctionner le spectromètre de masse en mode piégeage pour piéger les ions dans le piège à ions, et on effectue le remplissage du piège à ions pour le temps de remplissage préalablement déterminé. Cela permet une utilisation maximale du piège à ions, tout en évitant des problèmes dus au remplissage excessif, provoquant des effets de charge d'espace.

Filed: 2002-09-26
Abstract: An apparatus and method for expanding a lower string of casing into frictional contact with an upper string of casing, and thereby hanging the lower string of casing onto the upper string of casing is provided. The apparatus substantially defines a lower string of casing having a scribe placed into the top end thereof. The lower string of casing is run into the wellbore, and positioned so that the top end overlaps with the bottom end of an upper string of casing already cemented into the wellbore. The top end of the lower casing string is expanded below the depth of the scribe into frictional contact with the upper string of casing. At the same time, or shortly thereafter, the top end of the upper string of casing is expanded. As the portion of the lower casing string having the scribe is expanded, the casing severs into upper and lower portions.

Abstract: An apparatus (10) for the fixed-film anaerobic digestion of flushed livestock manure includes an enclosed digester tank (20) (fixed or flexible roof), internal media (34) for biofilm development, a biogas collection and flare system, various pumps, and hydraulic control systems. The preferred media has substantially vertically-oriented, uninterrupted channels to promote enhanced bacterial attachment and biofilm development. The immobilization of microbial biomass within the reactor as a biofilm allows effective treatment of the wastewater at ambient and higher temperatures, as well as reasonable hydraulic retention times. The composition and concentration of bacterial groups in the biofilm developed on the media in the fixed-film digester result in a significantly enhanced anaerobic degradation process. This novel fixed-film digester design expands the potential application of anaerobic digestion to dilute livestock waste with significant levels of suspended solids. This holistic manure treatment system not only stabilizes the wastewater but also produces energy (biogas ), controls odors, reduces pathogens, minimizes environmental impact from waste emissions, and maximizes fertilizer and water recovery for reuse.
