Abstract:
The invention consists of a system for opening and emptying capsules in a powder inhaler for administering medications The inhaler according to the invention has a chamber with a system for opening the medication capsule in which the process of opening and emptying the medication capsule takes place as well as an aerodynamic chamber in which the medication particles are separated from the carrier capsules. The aerodynamic chamber may also be used as a mouthpiece.
Abstract:
A probe for measuring the viscosity of small quantities of liquids is described. The probe for measuring the viscosity of liquids, including a housing having a surface, a first end point, and a second end point, the housing having a first, a second, and a third segment, an electric cable clamp being fixed at the first end, a transducer with electrodes on the surface of the housing, a rod containing a surface to which is glued the electrodes, the rod having a length with a free end, nodal points are attached to the first, second, and third segments of the housing, and, a clamp attaches the rod to the nodal points.
Abstract:
The present invention relates to a method for manufacturing a pleated filter (1) obtained by pleating a filtering material and folding the pleated filtering material to form a cylindrical configuration, which method further comprises applying at least one layer of fibrous covering on the outer surface of ridges of the pleats, which fibrous covering comprising melt-blown fibres (3) of thermoplastic polymer, wherein the pleated filter (1) is arranged in parallel to the blowing head which blows the molten polymer forming fibres, whereas at the same time the filter (1) performs rotational movements and/or reciprocating motions, while the distance of the blowing head from the said outer surface of the filter (1) is selected so that the fibres blown from the head from the said outer surface of the filter (1) is selected so that the fibres blown from the blowing head at the time of contacting the pleat ridges are still in a plastic state.The application provides further a pleated filter containing a pleated filtering material folded to form preferably a cylindrical configuration, on the outer surface of which filter the covering layer manufactured according to die method of the invention is arranged.
Abstract:
The invention consists of a powder inhalator for administrating medications. The inhalator, according to the invention, has a chamber with a mechanism for opening the medication capsule and an aerodynamic chamber in which the medication particles are separated from the currier capsules. In the aerodynamic chamber. On the opposite side to the mouthpiece opening, there are air inlet ducts which form a multidirectional system of air ducts. The air ducts are shaped in a way which makes the air that flows through them create at least three streams. Due to the intersecting of the air streams the air flow is strongly turbulent even if low speeds are involved. Consequently the separation of the active substance particles form the carrier surface is very effective.
Abstract:
Method and apparatus are provided for making a filter element by spinning fibers from one or more dies onto a collector, including designated combinations providing designated filter characteristics.
Abstract:
A coalescer has variable characteristics including variable diameter of individual fibers along their length such that an individual fiber has differing diameters at different points along its length, and including variable porosity.
