Patent YU-62193-A (YU)
Title: Postupak dobijanja diazodinitrofenola
Inventor: BOSNJAKOVIC M
Filed: 1993-09-27
Abstract: Postupak dobijanja diazodinitrofenola pripada oblasti organske tehnologije, odnosno oblasti tehnologije dobijanja inicijalnih eksploziva. Tehnički problem može se definisati kao zahtev da se dobije sipki diazodinitrofenol, nasipne gustine iznad 0,5 g/cm3. Ovaj problem je rešavan na razlifite načine, a najčešće dodavanjem nekih površinski aktivnih materija ili sredstava koja treba da služe kao centri kristalizacije u toku procesa diazotovanja pikraminske kiseline ili natrijumpikramata. Ideja pronalaska je da se izborom optimalnih parametara procesa dobije sipki proizvod, bez ikakvih dodataka. Pronalazak se u odnosu na poznata rešenja dobijanja diazodinitrofenola razlikuje u nižoj koncentraciji (5%) suspenzije natrijumpikramata, višoj temperaturi (26-30В°C) reakcije i u korišcenju matičnog rastvora iz prethodne šarže za pripremu suspenzije natrijumpikramata.

Abstract: Application for Patent of Lloyd R. Walsh and James M. Early for CHARGE-COUPLED AREA ARRAY     Abstract of the Disclosure A charge-coupled area array comprises a two-phase, buried channel semiconductor charge-coupled device (CCD) array which combines vertical CCD shift registers interdigitated and distinct from columns of light-sensing CCD elements.  Two electrically isolated levels of doped polycrystalline silicon are utilized for the gate electrode structures of the CCD shift register elements and the light-sensing CCD elements of the array,  Both of the doped polycrystalline gate electrode layers (vertical transport gates and frame gates) cooperate with barrier semiconductor regions of the array to permit bits of information (charge packets) generated in the light-sensing CCD elements to be laterally transported into the vertical CCD shift registers associated with the light-sensing CCD elements.  One of the doped polycrystalline silicon gate electrode layers (vertical transport gates) is used to provide clock pulses to vertically move the charge packets within the shift register CCD elements of the array.  These semiconductor barrier regions are of the same conductivity type as the buried region used to transport charge packets in the array.  Insulating layers including silicon nitride are used to electrically insulate the semiconductor surface and the doped polycrystalline silicon gate electrode layers from each other.

Abstract: Abstract of the Disclosure Hydroformylation of 1-propenyl acetate under hydro-formylating conditions with a cobalt hydroformylation catalyst produces 4-acetoxybutyraldehyde as the predominant component of a mixture with its two isomers, 2-acetoxybutyr-aldehyde and 3-acetoxy-2-methylproplonaldehyde.  Some reduction of these aldehydes to their corresponding alcohols also occurs.  The yield of these alcohols can be increased to the point where they  are the predominant products, either by increasing the reaction temperature, at least for the terminal portion of the reaction period, or by use of phosphine -modified cobalt hydroformylation catalyst.

Abstract: ABSTRACT OF THE INVENTION       A lightweight, active thermal control mechanism for space-craft use comprised of woven or unwoven cross-layered yarns where one set of yarns are composed of flexible electrically conductive metal fibers which are capable of being resistance-heated by the application of voltage and another set of yarns which are electrically non-conductive and flexible.  The non-conductive yarns provide mechanical strength and preclude the passage of electrical current between metal yarns by virtuc of the spacing between them.  A lightweight, electrically non-conductive film is bonded to the cross-layered yarns to protect the metal yarns from the elements (minimize electrical shorts from moisture, e.g., rain), provide additional strength to the fabric and to prevent the conductive loss of heat in non-vacuum applications.  The non-conductive film is metalized on its obverse side to provide a more uniform heat load distribution.

Abstract: S P E C I F I C A T O N        SHRINKAGE INHIBITION OF CEMENTITIOUS SYSTEMS    THROUGH THE ADDITION OF SPECIALLY  PROCESSED CARBONACEOUS MATERIALS     Inventor:  ROBERT W. GAINES                 ABSTRACT OF THE DISCLOSURE          Naturally occurring particulate carbonaceous mater-ials are rendered capable of inhibiting shrinkage when added to cementitious systems by special processing including heat treatment at temperatures substantially higher than drying temperature.  Further advantageous properties are obtained by contacting the material with a water spray at the heating temperature.  The treatment enhances the properties of car-bonaceous materials which are already capable of inhibiting shrinkage in the cementitious systems.  Shrinkage inhibition is also obtained by adding anthracite coal to a cementitious system.  Bleeding is eliminated by the addition of a particu-late carbonaceous material which will inhibit shrinkage.

Abstract: ABSTRACT OF THE DISCLOSURE           A fluid pressure operated impact mechanism of the type having a reciprocating working member guided for movement along an axis toward and away from a stop  member, a pressure chamber between the working and stop members to receive a fluid pressure medium to exert forces separating the two members, and pressure sealing means for maintaining the pressure  chamber sealed as the working member and stop member separate.   The  mechanism is char-acterized by a sealing arrangement   which requires few precision parts yet is applicable to a variety of different devices.   In the sealing arrangement, the pressure chamber is formed in the surface of at least on  of the members, so that the two members meet along a separating line at the periphery of the pressure chamber.  One of the members forms a support  wall or flange extending in an axial direction along the  separating line, and a flexible sealing means extends from the support wall of the one member to the other mem-ber, thereby effecting a seal therebetween.   The sealing means is supported radially against  the outward force of the pressure medium by the support wall,  and is arranged to be elastically deformed in the axial direction by the pressure  medium, thereby to maintain the pressure chamber sealed as the working member separates from the stop member.  When the limit of deformation is reached and the seal is broken, the sealing means elastically returns to its re-laxed condition to vent the pressure medium from the chamber and to permit  the working member to reciprocate back toward the stop member to again form a seal therebetween.   The sealing means, which can be an O-ring or bellows, preferably has an axial dimen-sion when relaxed of just less than twice the axial height of the support wall.
