Patent YU-19501-A (YU)
Title: Orally administrated controlled drug delivery system providing temporal and spatial control
Inventor: TALWAR NERESH
IPC: A61K9/46
Filed: 1999-01-19
Abstract: A pharmaceutical composition in the form of tablets or capsules provides a combination of temporal and spatial control of drug delivery to a patient for effective therapeutic results. The pharmaceutical composition comprises a drug, a gas generating component, a swelling agent, a viscolyzing agent, and optionally a gel forming polymer. The swelling agent belongs to a class of compounds known as superdisintegrants (e.g., cross-linked polyvinylpyrrolidone or sodium carboxymethylcellulose). The viscolyzing agent initially and the gel forming polymer thereafter form a hydrated gel matrix which entraps the gas, causing the tablet or capsule to float so that it is retained in the stomach or upper part of the small intestine (spatial control). At the same time, the hydrated gel matrix creates a tortuous diffusion path for the drug, resulting in sustained release of the drug (temporal control). A preferred once daily ciprofloxacin formulation comprises 69.9 % ciprofloxacin base, 0.34 % sodium alginate, 1.03 % xanthan gum, 13.7 % sodium bicarbonate, 12.1 % cross-linked polyvinylpyrrolidone, and optionally other pharmaceutical excipients, the formulation being in the form of a coated or uncoated tablet or capsule.

Abstract: Postupak za dobijanje supstance za proizvodnju papira i kartona iz otpadne sulfitne lužine celuloze sastoji se u tome što se otpadna lužina iz proizvodnje celuloze, koja predstavlja nevlaknasti materijal koji ima vrednost pH 1,5-2,0, podešava na pH 4,0-4,5 pomoću zasićenog rastvora natrijum karbonata ili 5% rastvora natrijum hidroksida. Tako dobijeni rastvor se prevodi u katjon aktivno stanje pomoću katjon aktivnih sredstava kao što su na primer poliamidamin polietilenamin i sl. Zatim se u tako dobijenu masu dodaju u odredjenim količinama karboksimetilceluloza, rastvor skroba i po potrebi neorganski pigmenti radi postizanja željene beline pri proizvodnji papira i kartona.Supstanca dobijena postupkom prema pronalasku supstituiše čak do 70 mas.% mase za proizvodnju papira i kartona, pri čemu papir i karton, dobijeni iz mase sa odredjenim sadržajem pomenute supstance, imaju izuzetna mehanička svojstva u odnosu na do sada poznata.Postupak prema pronalasku je od velikog ekološkog i ekonomskog značaja s obzirom da se lužina iz proizvodnje celuloze ne ispušta sa otpadnim vodama i da se celokupna masa sirovine za dobijanje celuloze 100% iskorišćava.

Title: Anchorage assembly for use in the prestressing of concrete structures
Inventor: KERR ROBERT M
IPC: E04C5/12
Filed: 1974-08-23
Granted: 1979-02-20
Abstract: ABSTRACT OF THE DISCLOSURE     An anchorage assembly for prestressed concrete structures comprises a bearing plate having a plurality of open-ings lying parallel to the central longitudinal axis of the assembly, each opening having a frusto-conical portion and a cylindrical portion in continuation thereof to receive a stranded stressing element.  A multi-part wedge device is positioned between the wall of each opening and its co-acting stressing element and, at least some of the openings are spaced from the longitudinal axis of the assembly so that the stressing elements co-acting therewith are caused to deviate towards the longitudinal axis of the assembly and relative to the axis of the openings.          The leading or narrow end of each wedge device extends into the cylindrical portion of its co-acting opening so that, due to the deviation of the co-acting stressing element, a portion of the wall of the leading end is deformed in a direction towards the longitudinal axis of the assembly and provides a gradual change in direction of the stressing element, which avoids undue stress of the latter.

Abstract: ABSTRACT OF THE DISCLOSURE A high voltage generating circuit for a television receiver which includes a horizontal oscillator and a switching circuit operating at the horizontal sweep frequency of the television receiver and being coupled to a flyback transformer which has an output resonant frequency in the vicinity of but higher than the horizontal oscillator frequency. The output of the flyback transformer is coupled to a rectifier circuit which in turn is coupled to the high voltage anode of the television receiver. The flyback transformer also has an input resonant circuit which includes a capacitor,which is serially connected to the primary winding of the flyback transformer. This series resonant circuit is resonant at a fre-quency in the vicinity but less than the frequency of the horizontal oscil-lator with the result that improved voltage regulation is obtained while avoiding excess high voltage which otherwise would be caused by a shift in the output frequency of the horizontal oscillator.

Abstract: Abstract of the Disclosure A TDM PCM communication system includes a plurality of user terminals, a switching network and a CPU for controlling the establishment of transmission paths between the user terminals and the switching network for the transfer of information between predetermined ones of the user terminals.  An incoming path carries information bits from the user terminals to the switching network and an outgoing path carries information bits from the switching network to the user terminals.  The switching network includes means for transferring single information bits each residing in a time slot period from the incoming path to the outgoing path.  The transferring means includes an exchange means for effecting a bilateral exchange of information bits in fixed pairs of time slot periods, whereby paths for information bit transmission are periodically provided between ones of the user terminals, as determined by the CPU.  PCM words are thereby exchanged bit by bit between user terminals enabled in fixed pairs of time slot periods.                                       -i-

Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates in general to connector filter assemblies.  Filters for connectors utilize the connector shell for a ground return and include respective capacitors connected between the connector contacts and the connector shell.  To provide sufficient filtering with the relatively small areas available in the coaxial arrange-ment of the pin contacts and capacitor plates, considerable elongation of the pin contact is required as compared with the standard length of a pin contact and precision fabrication together with individual handling may be required.  The present invention provides a mass produc-tion connector assembly by employing a capacitor assembly having axially spaced radially extending capacitor plates carried by a ceramic or dielectric member.  One plurality of plates are connected in common to the connector shell and other radially extending axially spaced plates are connected to respective contacts of the connector to form a filter capacitor for each contact.  A conductive elas-tomer or metal spring engaging one of the common plates under axial pressure ensures a secure electrical ground connection between the plates common to the connector contacts and the shell while a metal spring preassembled to each contact at an axial position coincident with the capacitor assembly exerts a radial outward pressure to ensure an electrical connection to the capacitor plates associated with the respective contact.
