Inventor: SPEIRS CHRISTOPHER J
IPC: A61K31/573
Filed: 2003-07-04
Abstract: An improved composition for controlling the release profile of an active compound through the intestinal tract comprises particles, especially pellets, containing the active compound, which are coated with a pH dissolution dependent coating material or a polymethacrylate material, which is preferably pH dissolution dependent, to a certain thickness depending upon the location and rate of release of the active compound that is desired. In preferred compositions, two or more pluralities of particles, in which particles of each plurality are coated with pH dissolution dependent coating material or polymethacrylate material to a different thickness to those of each other plurality, are contained within an enterically coated capsule and provide release of the active compound at various desired locations in the intestinal tract.

IPC: C11C3/10
Filed: 2003-12-23
Abstract: "PRODUçãO E PURIFICAçãO DE éSTERES DE áCIDOS LINOLéICOS CONJUGADOS". Um processo é previsto para refinar ésteres de ácidos linoléicos conjugados via destilação em uma operação de destilação com passagem única ou múltipla. A redistribuição térmica dos componentes de ácido linoléico conjugado durante a destilação é impedida ou reduzida, pelo uso de um aparelho de destilação com baixo tempo de permanência e/ou pressão reduzida. Um processo para produzir ésteres de ácido linoléico conjugado também é fornecido. o processo transesterifica um óleo contendo ácido linoléico, para gerar uma composição de éster alquílico, que depois é submetida à isomerização em temperaturas tipicamente entre cerca de 90-140 <198>C, para formar uma corrente de ésteres contendo ésteres de ácido linoléico conjugado, que é então destilada, para se obter os ésteres refinados de ácidos linoléicos conjugados. As etapas de transesterificação e isomerização podem ser executadas em um vaso de reator sem uma etapa de destilação interveniente. As etapas de transesterificação e isomerização podem ocorrer ao mesmo tempo em um sistema de reação contínuo, usando-se um aparelho com dupla zona de reação. Composições de ésteres refinados, produzidas pelos processos e enriquecidas em isómeros desejáveis de ácido linoléico conjugado, são também contempladas.

Abstract: A process for the preparation of urea in which a carbamate- and free ammonia-containing urea synthesis solution is formed from carbon dioxide and excess ammonia in a synthesis zone at a pressure of 125-350 bar, at least a portion of the carbamate present in the urea synthesis solution is decomposed in a stripping zone at the pressure of the synthesis zone or at lower pressure by heat supply and countercurrent contact with a stripping gas, the carbamate decomposition products, together with a portion of the excess ammonia and the stripping gas, are removed from the stripping zone as a gas mixture, at least a portion of the gas mixture obtained is condensed in a condensation zone and the stripped urea synthesis solution is processed into a urea solution or solid urea. The process is characterized in that in the condensation zone also at least 30% of the equilibrium amount of urea achievable under the reaction conditions is allowed to form and the carbamate- and urea-containing mixture is supplied to the synthesis zone. By preference, urea formation is continued until 50-80 %, of the way to the equilibrium has been covered.

Abstract: A device for loading containers that are open or can be vented, containers for fine particulate materials, said device being part of a pneumatic conveyance system, in particular such a system using dense layer transportation, where the said device comprises essentially a tube-shaped casing, a lifting element, a closing element and a lifting rod which connects the lifting and closing elements and enables the distance between these elements to be varied. The combined weight of the part of the lifting element, that can be moved in the axial direction (A), the closing element and the lifting rod is greater than the elastic force of the lifting element but is smaller than the product of the difference between areas (FH) and (FM) and the positive pressure in the supply line acting on the lifting element. The distance (h) of the closing element from the lower edge of the casing is smaller than the stroke of the lifting element. The device can be employed on an alumina silo for charging fused salt electrolytic cells used in the production of aluminum, on a plastic powder silo, a cement silo or a quartz silo for foundries.

Abstract: The invention proposes a liquid filter for purifying lubrication oil of an internal combustion engine, having a vertically arranged filter housing 10 which is closed at the top by a removable cap 12. In this filter housing there is a filter insert 18, which can be removed for servicing and, in the filter housing, separates a space 41 for dirty liquid from a filtrate space 42. 
<??>When the cap 12 is opened and the filter insert 18 removed, the liquid drains off via a drain passage 17. This drain passage 17 is provided with a shut-off device 25 which blocks the drain passage 17 when the filter insert 18 is inserted and frees this drain passage 17 when the filter insert 18 is released. The shut-off device 25 is designed as a compact unit which can be assembled and checked outside the filter housing 10 and can be used for filter housings of differing sizes.

Abstract: In a component system, especially for the construction of devices for holding, clamping and/or positioning workpieces, there is a basic unit (1) extending in the X-Y plane and at least one clamping component (2) which can be secured thereto in various selectable positions. The basic unit (1) has projections (3) regularly arranged in a grid in the X-Y Plane with areas designed as supporting surfaces (4). These projections (3) have reference surfaces (11) pointing in the Z direction and undercuts to accept connecting components. The connecting components extend between the projection (3) and the clamp (2). On each projection there are two spaced superimposed reference surfaces (5; 6). The reference surfaces are separated by the undercut. The component system provides great flexibility in positioning or location while conferring great stability and reproducibility. This makes it possible to interconnect matching joining components between the basic unit (1) and the clamping component (2).

Abstract: A method of preparing a catalyst particularly useful in the reaction of ethylene, oxygen and acetic acid in the vapor phase to form vinyl acetate comprises impregnating a porous support with water soluble salts of palladium and gold, fixing the palladium and gold on the support as water insoluble compounds by immersing the impregnated support in a reactive solution and tumbling the impregnated support in the reactive solution for at least 1/2 hour to begin precipitation of the insoluble compounds and completing precipitation of the insoluble compounds on the support and reducing the insoluble compounds to free palladium and gold. The catalysts prepared in this manner have been shown to provide improvement with respect to reduced selectivity to CO2 during the vinyl acetate forming reaction.

Abstract: A papermaker's fabric (10) having a smooth surface and a prolonged life includes flat machine-direction (MD) yarns (26, 28) which define the upper and lower surfaces (12, 14) thereof. The fabric has two layers (16, 20) of cross-machine direction (CD) yarns (18, 18', 22, 22'), each of which is interwoven with the flat MD yarns (26, 28). Other MD yarns (24), of round cross section, weave with the CD yarns (18, 18', 22, 22') in the two layers (16, 20) to bind the two layers together. The knuckles of these round MD yarns (24) are within the fabric (10) with respect to the planes defined by the flat MD yarns (26, 28), and, as a consequence, are less susceptible to degradation by heat and abrasion. The round MD yarns (24) may form loops (30) to seam the fabric. A longer fabric life follows from the protection of the round MD yarns (24) by the flat yarns (26, 28). The papermaker's fabric (10) is particularly useful as a dryer fabric on the dryer section of a papermachine.
