Title: Method for the preparation of 3- (2- benzothiazolyl)- 8- hydroxycumarinimine
Inventor: DRJANSKA VENETA D
IPC: C07D311/04
Filed: 1990-03-23
Abstract: The compound, prepared by this method can be applied in the chemical industry as lumiphor within the spectrums visible part and as a starting product for obtaining other cumarines. It has higher yield and purity. The method ensures savings, since the number of working operations is reduced and no catalyser is used thus purification of waste rinsing waters containing sodium hydroxide is no more necessary. It consists of the interaction of 2-benzothiazolyleacetonitrile with 2.3-dihydroxibenzaldehide by boiling for 10 min in ethanol medium.

Abstract: La présente invention concerne des compositions à base de mélanges de composants liquides et solides permettant la formation d'un biomatériau durcissant spontanément et présentant une large gamme de propriétés et de fonctions. L'invention porte plus particulièrement sur a) un composant liquide thermosensible se gélifiant spontanément, ce composant étant à base hydrique et comprenant au moins un polycationique et une source de phosphate, auquel cas le composant liquide est une solution thermo-gélifiante à un pH se situant entre 6,5 et 7,4, et sur b) un composant pulvérulent constitué d'au moins deux sources de phosphate de calcium. Les sources de phosphate de calcium préférées sont essentiellement les apatites, les phosphates tricalciques, les phosphates tétracalciques et les phosphates bicalciques. Les deux composants, le solide et le liquide, sont amenés à se mélanger de façon à former un coulis fluide qui en se solidifiant in situ donne un biomatériau durci à base de phosphate de calcium.

Patent CA-2001544-A1 (CA)
Inventor: APEL HOWARD L
IPC: C10L10/18
Filed: 1989-10-26
Abstract: Low heating value liquid hydrocarbonaceous and/or solid carbonaceous hazardous waste materials from the production, refining and marketing of petroleum products are destroyed without contaminating the environment while simultaneously gaseous mixtures comprising H2 + CO i.e.  synthesis gas, reducing gas, or fuel gas are produced.  From about 0.3 to 2.0 wt. % of an anionic surface active dispersant and water (if needed) are mixed with the hazardous waste material to produce  a  first  aqueous  mixture.   A  comminuted  solid carbonaceous fuel i.e. coal, petroleum coke is mixed with water and from about 0.02 to 1.00 wt. % of the dispersant to produce a second stable pumpable aqueous slurry.  The first and second aqueous slurries are mixed together to produce a stable pumpable final blend aqueous slurry which is reacted in a partial oxidation gas generator as the feedstock.  It was  unexpectedly  found  that  to  achieve  slurries  with satisfactory  rheological  properties  from  mixtures  of hazardous waste material and coal or coke slurries, it was necessary to add the dispersant to the coal/coke slurry as well as to the slurry of hazardous waste material before combining the two aqueous mixtures together.

Title: Process for the production of nitriles and oxides
Inventor: RAMACHANDRAN RAMAKRISHNAN
IPC: C07C253/34
Filed: 1990-01-16
Abstract: An improved process is provided for the production of nitriles  and oxides  from hydrocarbons by  reaction with oxygen, air or a gas enriched in oxygen relative to air, preferably the  latter,  and  ammonia  where  a  nitrile  is desired,  in  the  presence  of  a  suitable  catalyst.   An alkane,  e.g.  propane,  is  converted  to  an  alkene  in  a catalytic dehydrogenator.   The product  stream is  intro-duced into an ammoxidation/oxidation reactor.  The product formed  therein  is  recovered  in  a  conventional  quench tower.   The pressure of  the  gaseous  effluent  from  the quench  tower  is  raised  and  it  is  introduced  into  an absorber/stripper unit to form a recycle stream containing unreacted alkane and alkene as well as a minor amount of oxygen,  typically  1-2  percent  by  volume,  and  a  waste stream  comprising  the  remainder  of  the  quench  tower gaseous phase.   The recycle stream is introduced into a selective oxidation unit  to remove the oxygen therefrom and then recycled to the dehydrogenator.  Flammability of the quench tower  gaseous effluent  and  the waste stream from the absorber/stripper is minimized by assuring that the nonflammability index (NFI) thereof is within certain limits.  The desired NFI is related to the total hydro-carbon  content  of  the  stream  and  may be  achieved, if required,  by the addition thereto of a gaseous flame sup-pressor.  The gaseous flame suppressor is removed with the absorber/stripper  unit  waste  stream  which  may  advan-tageously be combusted to provide energy for the process. A PSA unit may be utilized to remove excess hydrogen from the dehydrogenator effluent.  The dehydrogenator may be a multistage dehydrogenator.

Abstract: TITLE OF THE INVENTION     BROADBAND NONLINEAR DRIVE CONTROL NETWORK FOR LINEAR AMPLIFIERS ARRANGED IN SEVERAL AMPLIFIER CHANNELS          ABSTRACT OF THE DISCLOSURE     A broadband nonlinear drive control network for linear ampli-fiers with several amplifier channels has a first branch with an adjustable amplitude limiter connected to a signal source through an impedance inverter, whereby an increasing impe-dance is produced at the signal source when the limiter kicks-in. A variable resistor is connected to the signal source in a second branch.  The resistor begins to conduct only above an adjustable high frequency signal voltage.  The amplitudes at the limiter and at the resistor are tuned to each other so that the load impedance at the signal source remains constant.  Linear branch signal combinations provide the drive control voltages for the individual channels.  A portion of the power output of the branch directly drives the amplifier channel.     2435/ar          - 1 -

Abstract: Abstract of the Disclosure An illuminated sign is comprised of single piece molded plastic  front,  intermediate and rear frame members which are substantially coextensive with the width of the sign.   All of the characters are formed on the intermediate frame member and they fit into a front frame which serves not only as a support but as a means for masking those parts of the interme-diate frame which connect between characters, for ex-ample, and which should not be illuminated.  The sign is hingedly mounted to a fixed support member which, in turn, supports fluorescent tubes which run along the length of the sign for illuminating the characters to make them visible at night as well as during the daytime.  The sign swings down on its hinges to its normal readable position wherein it is secured to the support member by means of quarter-turn fasteners which effectuate a seal by compressing a gasket which is interposed between the sign and the supporting structure.
