Abstract: FIELD: industrial organic synthesis. 
     SUBSTANCE: invention relates to improved method for reduction and recovery of unreacted ammonia from flowing out stream containing acrylonitrile or methacrylonitrile and coming out from reaction zone, where oxygen, ammonia, and hydrocarbon selected from propane and isobutene are brought into contact in reactor in presence of fluidized ammoxidation catalyst bed at elevated temperature to produce corresponding unsaturated nitrile by cooling flowing out stream containing corresponding nitrile and unreacted ammonia with first aqueous ammonium phosphate solution, wherein ratio of ammonium ions to phosphate ions (PO       3-   4       ) varies between 0.7 and about 1.3, to absorb essentially all unreacted ammonia present in flowing out stream to form second aqueous ammonium phosphate solution more rich in ammonium ions than the first solution. Second solution is then heated to temperature high enough to reduce amount of ammonium ions in the second solution to essentially the same level as in the first solution and to form ammonia-containing vaporous stream, which is returned into reactor.

Title: Method and system for optimization of program transmission to many users and receiver for program reception and planning device used in the system
Inventor: De Bei Henry Kurtis
IPC: H04N21/658
Filed: 1990-08-23
Abstract: A method for optimization of program transmission to many users consists in that programs are transmitted through a distribution system. In a head part of the distribution system the program is formed divided into majority of program segments for realization of planning algorithm which place the program segments in the set sequence. The program segments are transmitted according to the planning algorithm with possibility of simultaneous transmission of any unit segment to more than one receiver. During the time required for normal reproduction of the program at least part of the program segments is transmitted more than one time simultaneously to few receivers without fixing in any time head unit and distribution system for the any separate receiver. In the receiving part of the distribution system transmitted program segments are stored in a receiver buffer storage for next reproduction. Therefore mentioned planning algorithm being used can assure reception by any receiver of all the program segments with possibility of sequential reproduction of the program with normal rate with simultaneous providing for transformability of the buffer storage structure which capacity will be less than capacity containing total program.

Title: Method and apparatus for automatic detection and prevention of fire hazard
Inventor: OESTLYNGEN TOM WILHELM
IPC: A62C3/07
Filed: 1995-12-01
Abstract: A fire hazard is automatically detected and a fire is prevented or extinguished in an automotive vehicle upon such vehicle being involved in a collision. The vehicle has an air conditioning system including a container and employing CO2 as a refrigerant. The occurrence of a collision is detected by an impact sensor. In response to detection of the collision by such a sensor, a processing/control unit opens a valve in a line connected to an outlet at or near a bottom of the container. Thereby, the CO2 refrigerant is released substantially in liquid phase from the container and passed through the line and is discharged as a fire extinguishing agent into various parts of the vehicle, for example the engine compartment.
