Title: Ultrasonic nebulising device
Inventor: CHEIMAN VLADIMIR
IPC: B05B17/06
Filed: 1993-10-15
Granted: 2005-04-12
Abstract: The device is designed for nebulizing liquids and for transporting the formed aerosols. It includes components to form a fountain of liquid that is being nebulized, a container holder (4), a container (2) with contact medium (3), an additional container (5) with liquid being nebulized (6), a nebulization chamber (7), a system for transporting the aerosol to the user, an outlet duct (11), and a mechanism for regulation of rate of delivery of aerosol. The nebulization chamber (7) is designed as a double-element structure, composed of an intake tube (8) and an expansion chamber (9). In the bottom of the expansion chamber (9) outlets (10) have been made for the drainage of the non-nebulized liquid back to the section of the container remote from the base of the fountain. This reduces the negative action of the non-nebulized liquid on the effectiveness of nebulization. The expansion chamber (9) which is incorporated into the nebulization chamber (7) ensures a significant reduction in coagulation of the aerosol particles, thus increasing the efficiency of the nebulizer and particle uniformity. The latter effect is likewise heightened by this specifically designed outlet duct (10) which accomplishes a process of gravitational filtration. As a consequence of the movement of the stream in the narrow intake tube (8) there is formation of a differential pressure, enabling transport of the aerosol from the nebulization chamber to the user. The above principles are proposed for application to multi-use and single-used devices.

Granted: 1999-01-12
Abstract: Voici la description d'une méthode et d'un appareil de gerbage et de transport d'articles. Les articles sont transportés par un convoyeur d'une station de chargement à une station de déchargement. Le convoyeur comporte plusieurs palettes s'étendant à partir de celui-ci, les palettes voisines les unes des autres définissant des récipients pour contenir des articles.  L'invention permet aux articles d'être réorientés pendant leur transport de la station de chargement à la station de déchargement afin que ceux-ci soient orientés correctement en arrivant à la station de déchargement. Cette fonction de réorientation élimine des étapes et des appareils séparés de transport et de réorientation. La présente invention effectue cette action en chargeant premièrement au moins un article dans un récipient et en le transportant le long de l'axe longitudinal du convoyeur. Les palettes sont ensuite réorientées le long d'une ligne généralement hélicoïdale pendant que les articles sont transportés de la station de chargement à la station de déchargement. Les palettes sont réorientées à un angle voulu en fonction de l'axe longitudinal du convoyeur.   la station de déchargement, les articles sont déchargés des multiples récipients et déposés pour former une pile. Les palettes sont ensuite réorientées pour reprendre leur position initiale du moment du chargement.

Abstract: When drying a paper web (4) in a dryer section (1) of a paper machine provided with drying cylinders (2, 3) and drying wires (5, 6), shrinkage of the paper web in cross direction is counteracted by applying forces at its edge portions (11). According to the invention partial vacuum is maintained along the edge portions of the web within substantially the entire free draw (10) and is applied from the side of the drying wire (5, 6) facing away from the web (4) so that the web is sucked firmly against the drying wire by forces greater than the contracting forces acting in cross direction, thereby counteracting shrinking, said partial vacuum being set within toe interval 0.1-0.8 bar, preferably 0.2-0.5 bar.

IPC: A61J1/00

Granted: 1999-12-28
Abstract: A bottle having a sterility seal and a method for producing same are disclosed. The bottle, which can be configured to retain a medicament in powder or tablet form, features a protective cap configured to engage a transfer assembly associated with the bottle. The cap includes one or more raised ridges on an interior surface engageable with a portion of the transfer assembly. A band or layer configuration of a sealing material such as silicone is applied to the transfer assembly prior to insertion of the cap thereover. As the cap comes into surface contact with the sealing material, the ridges cause the material to "roll up" into a toroidal O-ring configuration, thereby forming a seal between the cap and the bottle adapted to the dimensional variations of those components. The seal, which is resilient, is able to withstand harsh handling treatment and pressure or temperature variations without separation from the cap or bottle, thereby providing a hermetic seal isolating the transfer assembly and, hence, the medicament from the outside environment.

Granted: 2001-11-20
Abstract: The present invention discloses an improved process for producing plastic containers with excellent resistance to permeation by solvents such as hydrocarbons, hydrocarbon fuels, and hydrocarbon fuels with organic additives including lower alkanols and ethers consistently and reliably. The process is related to a treatment of plastic containers in a controlled manner with fluorine containing gases while blow molding them. In the process of the present invention, an article of manufacture, a container, is formed and subjected to fluorination by exposure to a fluorination gas. After the fluorination, the container is quenched by exposing the container to a fluorine reactive gas to react with the fluorine, thereby converting the fluorine to a less reactive gas.

Title: Paging technique for personal communications systems and apparatus for implementing the same
Inventor: ELWIN RANDOLPH G
IPC: H04W68/00
Filed: 1998-01-05
Granted: 2002-06-11
Abstract: In  a  distributed  communication  system  such  as  a personal handyphone system, when a new call must be connected through a cell station, the PNC unit associated with the cell station checks to see if the cell station is fully loaded.  If so,  portable  telephones  currently  having  calls  connected through that  cell  station  are checked  to  see  if  they  can reconnect  to  a  different  cell  station.    If  so,  they  are directed to reconnect, thereby freeing a space on the target cell station so that the new call can be connected.   This technique is useful for incoming calls from a wireline network, outgoing calls from a portable telephone,  and handoffs of a roaming portable telephone.

Title: Extrapolation of pixel value of a video object within a block boundary
Inventor: LEE MING-CHIEH
IPC: H04N7/36
Filed: 1996-10-04
Granted: 2003-09-16
Abstract: Video encoding and decoding processes provide compression and decompression of digitized video signals representing display motion in video sequences of multiple image frames. The encoder process utilizes object- or feature- based video compression to improve the accuracy and versatility of encoding interframe motion and interframe image features. Video information is compressed relative to objects or features of arbitrary configurations, rather than fixed, regular arrays of pixels as in conventional video compression methods. This reduces the error components and thereby improves the compression efficiency and accuracy. The decoder process decompresses the encoded video information to reconstruct the objects or features of arbitrar y configurations.
