Patent FI-87424-C (FI)
Inventor: CALANCHI MASSIMO
IPC: A61K9/14

Abstract: The object of the present invention is a process which permits the increase of the bioavailability in the solid formulations of nifedipine and its derivatives. In consists in dissolving the active substance together with a polyethylene glycol, in a common solvent, then absorbing this solution on a micronized, inert excipient, soluble in the gastrointe­stinal juices, and finally, co-precipitating the active substance and the polyethylene glycol by evaporating the solvent.The very large surface of the excipient on which the solution is absorbed, and the presence of polyethylene glycol, wich facilitate the homogeneous distribution of the solution on this surface, permit the active substance to precipitate and become very fine particles.The same results may be also obtained by blending homogeneously the micronized inert excipient with micronized nifedipine, and causing the mixture to be absorbed on a solution of polyethylene glycol, which by subsequent solvent evaporation, precipitates in fine particles that are homogeneously dispersed and in intimate contact with the active substance.Forms of solid dosage prepared with the mixture thus obtained, have shown a bioavailability higher than similar formulations already on the market.

Abstract: A process and a device for gluing materials with curable aminoplastic adhesives with separate application to the joint of a resin component of the adhesive and a hardener component containing an acid or an acid-forming substance. The application is simplified and the separate application on one and the same joint surface of both components is made possible by first applying the hardener component in the form of an aqueous solution to the joint surface by means of a roll which is porous and capable of absorbing hardener composition and that the resin component is subsequently applied to the same joint surface. Preferably this is also applied by means of a roll. A suitable device for carrying out the process comprises a roll having a porous and absorbing material on its surface and a dosage roll which is in contact with this and between which rolls the hardener component is supplied.

This material reacts endogenetically and emits a fire-inhibiting gas when heated substantially. The bulk of the fire-retarding material is provided in the adapter block. The chamber is formed by an axially inwardly open pocket and a plug axially inwardly closing the pocket. More particularly the block is then formed with a relatively narrow slot extending between its inner surface and the chamber. The chamber opens via the slot radially at the inner surface. The block can be formed with a plurality of such chambers and slots spaced angularly around the axis. The inner surface of the block is formed with a radially inwardly open circumferential groove crossing and interconnecting the slots.

Abstract: A pumping system (10) is capable of handling a paper pulp suspension of medium consistency (e.g. about 8-15% solids consistency) utilizing a conventional centrifugal pump (12). A conventional pump system capable of handling 3-8% consistency pulp may be retrofit to handle 8-15% consistency pulp. A tube (30) with vanes (33), and having an open end (37), extends through the inlet (15) to the pump so that there is a small clearance (35) between the vanes and the inlet, and so that the open end is adjacent but spaced from the hub (18) of the pump impeller (17). A gas passage (48) extends from the hollow interior of the tube to an area remote from the pump. The tube is rotated in a direction of rotation opposite to the direction of rotation of the pump impeller, and at a speed sufficient to fluidize pulp of about 8-15% consistency, and to force the pulp toward the pump. Gas which collects at the pump impeller is withdrawn through the tube and the gas passage in a shaft (39) connected to the tube, and for that purpose a vacuum pump (52) may be utilized.

Granted: 1999-07-06
Abstract: The present device, a vital power controller with forgiveness, is a subsystem of a larger vital processing system,  the function of the subsystem being to verify the proper operation of the larger system and to provide power to the system outputs only when the larger system functions  correctly;  the  larger  system periodically delivers checkword sets to the vital power controller (VPC); the checkwords verify the correct operation of the larger system, a valid checkword set enabling the VPC to generate vital power for a limited time; the forgiveness feature allows the VPC to tolerate an occasional bad checkword set and yet continue to provide vital power if the rate at which bad checkword sets is encountered is below -a specified rate, thereby providing improved performance in the presence of noise which tends to produce occasional bad checkwords and which would otherwise cause loss of vital power.

Granted: 1994-10-11
Abstract: ABSTRACT      A compact,  low shipping volume paper product comprising a compression loaded, core-wound roll  of paper and a compression constraining element;  and concomitant method of making such  a paper product.  The roll  comprises a length of paper which is wound on a tubular core, and which roll may have an obround or parallelopipedal shape due to being unidiretionally compressively loaded after winding; and then constrained against expanding by a suitable   constraining   element.    Preferably,   the   roll   is sufficiently compressively loaded to completely flatten the core. In  another  aspect of the  invention,  the roll  may be  further compressed by applying a compressive loading that is substantially greater than that needed to cause the core to become flat; and, some of that high compressive loading may be relieved before the constraining element is applied or secured.  The paper product is susceptible to being reshaped by a consumer upon removal of the constraining element so that both the product and the core become somewhat round in cross section.  Such a product may, for example, be a contemporary roll of toilet tissue or disposable paper towels on a contemporary paperboard core.  The paper product may comprise a plurality of such rolls, and may be constrained by enclosures such as polyethylene film,  and/or bands about individual rolls, and/or a band about an array of rolls.

Abstract: This invention describes a process and apparatus for the combustion of wastes, wherein the wastes are combusted in a combustion chamber and the temperature of the combustion chamber is controlled by changing the amount of combustion air as a function of the slag flow rate. The combustion can be carried out substoichiometrically in a reducing atmosphere because of additives which are introduced into the slag in the form of fine dusts. On account of the substoichiometric operation, the requirement for fluid wastes and/or supplemental fuel is drastically reduced, the capacity of the rotary tubular kiln is increased and nitrogen oxides formation is reduced.

Abstract: A method and apparatus for forming and selectively interrupting one or more fluid stream which is confined within an open channel. A transverse fluid stream is introduced into the channel at a point under the stream flowing within the channel. Introduction of the transverse stream at relatively low pressures is sufficient to cause the stream within the channel to leave the confines of the channel. If the channel is directed at a target, the method and apparatus will allow intermittent and selective interruption of a fluid stream flowing within the channel and directed at the target. The source of the transverse fluid stream has an arcuate or curved outlet portion to prevent fluid from the open channel from accumulating therein.
