Patent DE-3581109-D1 (DE)

Granted: 1991-02-07
Abstract: This invention relates to fiber optic frequency shifters for producing optical signals of a desired frequency range for input to a device such as an optical rotation sensing system. The rotating birefringence is created in a length of fiber optic material, which has the effect of a rotating half-wave plate upon an input optical signal. The length of fiber optic material may have a jacket of either an electrostrictive or a magnetostrictive material formed thereon such that application of an appropriate field to the jacket compresses the enclosed fiber to induce birefringence therein by means of the photoelastic effect. A half-coupler having a block of electro-optically active birefringent material adjacent the interaction region combined with an electrode configuration and circuitry for producing a rotating electric field in the block also produces a rotating half-wave plate frequency shifter. The evanescent field of light propogating in the optical fiber interacts with the rotating birefringence and experiences a frequency shift. The invention also includes feedback circuitry for processing the optical output of fiber optic rotating half- wave plates to maintain the intensity of components in the output signal having the carrier frequency below a threshold value.

Abstract: A circuit and method for a display coptroller especially adapted for display memories organized in arrays. The invention permits high speed modification of the contents of a display by generating the address signals of a selected linear pattern as the data block to be modified is retrieved from the display memory. For vectors, the addresses are generated in the same time as required for data block retrieval. The invention also permits calculation of the addresses of simple curves as the data block to be modified is retrieved, though calculation times typically are longer than for vectors. Modified Breshenham's algorithm is used for the address calculation.

Granted: 1989-04-06
Abstract: Disclosed is a process for removing sulfur oxides and optionally other gaseous pollutants from flue gases by means of a reactant which is contained in a circulating fluidized bed and contains sodium, potassium, calcium and/or magnesium as a cation and oxide, hydroxide and/or carbonate as an anion. The adaptation to all operating conditions of the plants by which the flue gas is supplied is simplified in that pollutants are removed from the flue gases when the temperature of the mixture of flue gas and reactant is not in excess of 50 DEG  C. above the dew point temperature of water vapor. The reactant is selectively charged at different locations in a dry form, on the one hand, and as an aqueous solution or suspension, on the other hand, the form in which the reactant is charged being controlled in dependence of the temperature and the SO2 content of the purified gas. If the reactant is charged in a liquid phase it has suitably a solids content of 5 to 30 wt. %, the temperature of the mixture of flue gas and reactant is maintained between 3 DEG  and 30 DEG  C. above the dew point temperature of water vapor and the means suspension density in the fludized bed reactor is maintained between 0.2 and 2 kg/m3.

Abstract: According to the application, a relatively low molecular weight epoxy resin is reacted with an acidic fusion compound in the presence of a bis(trihydrocarbylphosphine)iminium salt catalyst to produce a high molecular weight fused epoxy resin. The process is particularly useful in reacting an epoxy resin having a molecular weight of less than 500 with 2,2-bis(4-hydroxyphenyl)propane in the presence of a bis(trihydrocarbylphosphine)iminium halide to produce a fused epoxy resin having a molecular weight within the range of 500 to 7000. The catalyst is relatively water-insensitive, and the reaction can therefore be carried out in the presence of water.
