Title: Satellite camera image navigation
Inventor: KAMEL AHMED A
IPC: B64G1/36
Filed: 1986-12-11
Granted: 1992-03-17
Abstract: ABSTRACT SATELLITE CAMARA IMAGE NAVIGATION     Pixels within a satellite camera  (1,  2)  image are precisely located in terms of latitude and longitude on a celestial body,  such as the earth, being imaged. A computer (60) on the earth generates models (40, 50) of the satellite's orbit and attitude,  respectively.   The orbit  model  (40)  is  generated  from  measurements  of stars and landmarks taken by the camera (1, 2), and by range data.   The orbit model  (40)  is an expression of the   satellite's   latitude   and   longitude   at   the subsatellite  point,  and  of  the  altitude  of  the satellite, as a function of time, using as coefficients (K) the six Keplerian elements at epoch.  The attitude model  (50)  is  based  upon  star  measurements  taken by each camera  (1,  2).  The attitude model  (50)  is a set of expressions for the deviations in a set of mutually orthogonal  reference  optical  axes  (x,  y,  z)  as  a function  of  time,  for  each  camera  (1,  2).   Measured data is fit into the models  (40,  50)  using a walking least squares fit algorithm.  A transformation computer (66) transforms pixel coordinates as telemetered by the camera  (1,   2)   into  earth  latitude  and  longitude coordinates,  using the orbit and attitude models  (40, 50).

Title: Electroconductive polymer - latex composites
Inventor: HAM GEORGE E
IPC: H01B1/00
Filed: 1987-06-18
Granted: 1993-03-30
Abstract: ABSTRACT          This invention relates to an electrically conductive polymer-latex composite comprising an organic polymeric material dispersed in a latex which is doped to provide an electroconductive polymer-latex composite.  The latex effectively serves as a carrier for the polymeric material.  A process for preparing the polymer-latex composite comprises mixing ah initially undoped organic material in powder form with a water-based latex, and then spreading and solidifying the mixture.        Conductive polymers are generally prepared from backbone polymers, such as polyacetylene, which are made electroconductive by molecular doping of the polymer.  Films made from these conductive polymers suffer from several disadvantages.  For example, polyacetylene films are very thin and often brittle.   31,764-F

Abstract: A single step method for preparation of multi-layer polymeric delivery systems.   Any two or three different degradable or non-degradable polymers which are not soluble in each other at a particular concentration, as dictated by their  phase  diagram,  can  be  used.    The  multi-layer microcapsules produced by the method are distinguished by extremely uniform dimensioned layers of polymer and actual incorporation of the substance to be delivered into the polymer layers.  In the preferred embodiment of the method, two polymers are dissolved in a volatile organic solvent, the substance to be encapsulated is dispersed or dissolved in the polymer solution, the mixture is suspended in an aqueous solution and stirred, and the solvent is slowly evaporated, creating microspheres with an inner core formed by one polymer and an outer layer formed by the second polymer.  In another embodiment one polymer may be formed within a layer of the other polymer by increasing the rate of evaporation of the volatile solvent.

Title: Optical fiber connector
Inventor: CARLISLE ARTHUR W
IPC: G02B6/38
Filed: 1988-06-27
Granted: 1992-12-15
Abstract: Abstract An optical fiber connector includes two plug assemblies each including a cylindrically shaped plug extending from within a cap. An end of each cap is adapted to be secured to a coupling housing to cause the plug which extends from the cap to be received in a sleeve disposed in the housing. An optical fiber cable extends through a cable entrance end of the cap and has an end portion of its optical fiber terminated by the plug. An extender of the cap is secured thereto and extends along the cable a distance to a location where portions thereof are closely adjacent to the cable. Bending forces applied to the cable are transferred at the location to the extender and thence to the cap. This avoids the transfer of those forces to the plug which otherwise could cause the plug to turn pivotally about an interior lip of the cap and result in an optical disconnection of the plug from the other plug in the sleeve.

Inventor: JULLIAN MICHEL
IPC: F42B3/12
Filed: 1988-07-18
Granted: 1994-04-26
Abstract: ABSTRACT OF THE DISCLOSURE An explosive device receives signals specifying a unique communications address for use in a blasting circuit and a required blasting delay. The device has an electric igniter, but no independent power source which might cause accidental detonation. In an address and delay setting mode, when the device is being handled by a blaster, a unipolar signal is transmitted to the device to charge only a control power supply for general communications. In a blasting mode, a bipolar signal is transmitted to charge both control and igniter power supplies. A security code must, however, be transmitted to enable charging of the igniter power supply. Prior to detonation, each explosive device in a blasting circuit responds to a calibration signal by generating a timing circuit test count. A blasting machine processes nominal delays and test counts, and transmits adjusted delays to synchronize operation. A firing signal is recognized only if it contains a predetermined number of coded components thereby providing immunity to electromagnetic noise. The device is safely removed from a blasting circuit by transmitting a disarming signal which causes its igniter power supply to be discharged.

Abstract: BIOLOGICAL TREATMENT OF SULFUR-CONTAINING WASTE GAS                  ABSTRACT OF THE DISCLOSURE        A biological conversion process is provided for degradation of sulfur-containing pollutants such as H2S, CS2, COS, and also organic sulfur compounds such as thio-alcohols, thio-ethers, and thiophenes in waste gas.  A packed reactor is provided which has packing material covered with immobilized microorganisms of the family of Thiobacillaceae and which are continuously kept moist, so that metabolic products of the microorganisms are dissolved in the moisture and discharged continuously.  A continuous concentration gradient for sulfate ions thereby results in the reactor or in the region of the microorganisms, these sulfate ions being neutralized in a second reactor by supplying lye (soda or potash lye) forming readily-soluble salts.  These readily-soluble salts are transformed in a third reactor by addition of milk of lime into crystals (gypsum crystals) which are poorly-soluble in water and with formation of lye for the second reactor capable of being recirculated so that loss of chemicals (lye) is principally minimized.  The poorly-soluble crystals from the third reactor can be discarded or utilized.  The low sulfate supernatant is then conveyed to the main canal, through a biological clarification plant.
